Answer:
$825.28
Step-by-step explanation:
First, we need to calculate the 15% off sale:
870(0.85) = 739.50
Now, we will calculate and add on the sales tax:
739.50(1.116) = 825.28
So, the final price of the dresser will be $825.28
Hence, the total cost of the dresser is $ [tex]15.138[/tex].
What is the percentage?
Percentages are generally defined as a ratio of any value to the whole value multiplied by [tex]100[/tex].
The symbol used to represent the percentage is %. Percentage means a number or a ratio represented in the form of fractions of [tex]100[/tex]. It is represented using the percentage sign ‘%’.
Here given that,
A dresser is normally priced at $[tex]870[/tex]. This weekend however, there is a sale where everything is [tex]15[/tex]% off. If the sales tax on items is [tex]11.6[/tex]%,
Firstly we will calculate the [tex]15[/tex]% off sale is
[tex]15[/tex]%[tex]=\frac{15}{100}\\\\[/tex]
[tex]15[/tex]%[tex]=0.15[/tex]
So,[tex]870(0.15) =130.5[/tex]
Then,
[tex]\frac{11.6}{100}=0.116[/tex] %
The sales tax on items is [tex]11.6[/tex]% is
[tex]130.5(0.116)=15.138[/tex] $
Hence, the total cost of the dresser is $ [tex]15.138[/tex].

If Sam and Sally invested the same total amount at the end of three years, the amount Sam invested the first year is $ and the amount Sally invested the last year is $ .
Answer:
The amount Sam invested the first year = $2000
The amount Sally invested the last year = $1900
Complete question related to this was found at brainly (ID 4527784):
For three consecutive years, Sam invested some money at the start of the year. The first year, he invested x dollars. The second year, he invested $2,000 less than 5/2 times the amount he invested the first year. The third year, he invested $1,000 more than 1/5 of the amount he invested the first year.
During the same three years, Sally also invested some money at the start of every year. The first year, she invested $1,000 less than 3/2 times the amount Sam invested the first year. The second year, she invested $1,500 less than 2 times the amount Sam invested the first year. The third year, she invested $1,400 more than 1/4 of the amount Sam invested the first year.
If Sam and Sally invested the same total amount at the end of three years, the amount Sam invested the first year is $ and the amount Sally invested the last year is $ .
Step-by-step explanation:
First we would represent the information given with mathematical expressions.
Sam investment for 3 consecutive years:
Year 1 = x dollars
Year 2 = $2,000 less than 5/2 times the amount he invested the first year
Year 2 = (5/2)(x) - 2000
Year 3 = $1,000 more than 1/5 of the amount he invested the first year
Year 3 = (1/5)(x) + 1000
Sally investment for 3 consecutive years:
Year 1 = $1,000 less than 3/2 times the amount Sam invested the first year
Year 1 = (3/2)(x) - 1000
Year 2 = $1,500 less than 2 times the amount Sam invested the first year
Year 2 = 2x - 1500
Year 3 = $1,400 more than 1/4 of the amount Sam invested the first year.
Year 3 = (1/4)(x) + 1400
Since Sam and Sally invested the same total amount at the end of three years, we would equate their sum:
Sum of Sam investment for the 3years = x + (5/2)(x) - 2000 + (1/5)(x) + 1000
= x + 5x/2 -2000 + x/5 + 1000
= (10x+25x+2x)/10 - 1000
= 37x/10 - 1000
Sum of Sally investment for the 3years = (3/2)(x) - 1000 + 2x - 1500 + (1/4)(x) + 1400
= 3x/2 - 1000 + 2x -1500 + x/4 + 1400
= (6x+8x+x)/4 - 1100
= 15x/4 - 1100
37x/10 - 1000 = 15x/4 - 1100
37x/10 - 15x/4 = -100
(148x - 150x)/40 = -100
-2x = -4000
x = 2000
Therefore the amount Sam invested the first year = x = $2000
The amount Sally invested the last year (3rd year) = (1/4)(x) + 1400
(1/4)(2000) + 1400 = 500+1400 = 1900
The amount Sally invested the last year = $1900

Large samples of women and men are obtained, and the hemoglobin level is measured in each subject. Here is the 95% confidence interval for the difference between the two population means, where the measures from women correspond to population 1 and the measures from men correspond to population 2: negative 1.76 g divided by dL less than mu 1 minus mu 2 less than minus 1.62 g divided by dL. Complete parts (a) through (c) below.
a. What does the confidence interval suggest about equality of the mean hemoglobin level in women and the mean hemoglobin level in men? Because the confidence interval does not include includes nothing, it appears that there is is not a significant difference between the mean level of hemoglobin in women and the mean level of hemoglobin in men. (Type an integer or a decimal. Do not round.)
b. Write a brief statement that interprets that confidence interval.
A. There is 95% confidence that the interval from minus 1.76 g divided by dL to minus 1.62 g divided by dL actually contains the value of the difference between the two population means left parenthesis mu 1 minus mu 2 right parenthesis .
B. There is 95% confidence that the difference between the two population means left parenthesis mu 1 minus mu 2 right parenthesis is either minus 1.76 g divided by dL or minus 1.62 g divided by dL .
C. There is 95% confidence that the difference between the two population means is not 0.
D. There is 95% confidence that the interval from minus 1.76 g divided by dL to minus 1.62 g divided by dL does not contain the value of the difference between the two population means left parenthesis mu 1 minus mu 2 right parenthesis .
c. Express the confidence interval with measures from men being population
1. and measures from women being population
2. Choose the correct answer below.
A. negative 1.62 g divided by dL less than mu 1 minus mu 2 less than 1.76 g divided by dL
B. negative 1.76 g divided by dL less than mu 1 minus mu 2 less than minus 1.62 g divided by dL
C. 1.62 g divided by dL less than mu 1 minus mu 2 less than 1.76 g divided by dL
D. negative 1.76 g divided by dL less than mu 1 minus mu 2 less than 1.62 g divided by dL.
Answer:
(a) Because the confidence interval does not include includes 0, it appears that there is not a significant difference between the mean level of hemoglobin in women and the mean level of hemoglobin in men.
(b) The correct option is (A).
(c) The correct option is (C).
Step-by-step explanation:
The 95% confidence interval for the difference between the two population mean hemoglobin level is:
CI = (-1.76 < μ₁ - μ₂ < -1.62)
(a)
The hypothesis to test the equality of the mean hemoglobin level in women and the mean hemoglobin level in men is:
H₀: The two population means are equal, i.e. μ₁ = μ₂.
Hₐ: The two population means are not equal, i.e. μ₁ ≠ μ₂.
The (1 - α)% confidence interval can be used to draw conclusion about the hypothesis test.
Decision rule:
If the (1 - α)% confidence interval does not consist of the null value then the null hypothesis will be rejected and vice-versa.
The 95% confidence interval for the difference between the two population means is:
CI = (-1.76, -1.62)
The 95% confidence interval does not consist of the null value, i.e. 0.
Thus, the null hypothesis will be rejected.
"Because the confidence interval does not include includes 0, it appears that there is not a significant difference between the mean level of hemoglobin in women and the mean level of hemoglobin in men."
(b)
The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.
Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.
So, the 95% confidence interval (-1.76, -1.62) implies that there is a 95% confidence that the above interval actually contains the value of the difference between the two population means, (μ₁ - μ₂).
The correct option is (A).
(c)
Now it is provided that the measures from men is denoted as population 1 and measures from women is denoted as population 2.
The confidence interval for the difference between two mean is:
[tex]CI=(\bar x_{1}-\bar x_{2})\pm MOE[/tex]
According to the information:
[tex]\bar x_{1}=\bar x_{2}\\\\\bar x_{2}=\bar x_{1}[/tex]
So, the new confidence interval will be:
[tex]CI=-(\bar x_{2}-\bar x_{1})\pm MOE[/tex]
Then the confidence interval with measures from men being population
1 and measures from women being population 2 is:
[tex]CI=(1.62<\mu_{1}-\mu_{2}<1.76)[/tex]
The correct option is (C).

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
A restaurant catered an event for 25 people.
A child’s dinner cost $5 and an adult’s dinner cost $22.
The party cost $431.
let the number of children attendee be x and adult attendee be y.
So, x+ y = 25..............(1)
and, 5x + 22y = 431.......(2)
Solving the Equation (1) and (2) we get
5(25 - y) + 22y= 431
125 - 5y + 22y= 431
17y = 431-125
17y = 306
y = 18
and, x= 25-18 = 7
Hence, there was 7 children attendee and 17 adult attendee.

Use the given information to draw a box-and-whisker plot of the data set
Minimum – 28
Maximum – 54
Lower Quartile – 32
Upper Quartile – 40
Answer:
The box-and-whisker plot of this distribution is presented in the attached image to this solution.
Step-by-step explanation:
A box plot gives a visual representation of the distribution of the data, showing where most values lie and those values that greatly differ from the rest, called outliers.
A box and whiskers plot shows 5 major information about the distribution of data. It shows:
- The maximum variable.
- The minimum variable.
- The Median.
- The first quartile.
- The third quartile.
Further info such as the range and Inter quartile range can then be obtained from this 5-number summary.
The elements of the box plot are described thus;
The bottom side of the box represents the first quartile, and the top side, the third quartile. Therefore, the width of the central box represents the inter-quartile range.
The horizontal line inside the box is the median.
The lines extending from the box reach out to the minimum and the maximum values in the data set, as long as these values are not outliers. The ends of the whiskers are marked by two shorter horizontal lines.
Variables in the dataset, higher than Q3+(1.5×IQR) or lower than Q1-(1.5×IQR) are considered outliers and are usually shown using dots above the top whisker or below the bottom whisker.
The required boxplot for this question is given in the attached image to this solution.
The median for the boxplot isn't provided, but it was assumed to be midway between the first and third quartile.

For Race A, the whiskers range from 120 to 170, and the box ranges from 143 to 165. A line divides the box at 153. For Race B, the whiskers range from 125 to 165, and the box ranges from 140 to 150. A line divides the box at 145. Average Speeds of Cars in Race B
Answer:
The median speed in race A is about 153 miles per hour, and the median speed in race B is about 145 miles per hour.
Step-by-step explanation:
For comparison, we need to analyze and compare both races data which are as follows
For Race A
Maximum range = 170 miles per hour
Minimum range = 120 miles per hour
First quartile ≈ 142 miles per hour
Median quartile ≈ 153 miles per hour
It comes from
[tex]= \frac{142\ miles + 165\ miles}{2}[/tex]
= 153 miles
The Third quartile = 165 miles per hour
For Race B
Maximum range = 165 miles per hour
Minimum range = 125 miles per hour
First quartile ≈ 139 miles per hour
Median quartile = 145 miles per hour
It comes from
[tex]= \frac{139\ miles + 150\ miles}{2}[/tex]
= 145 miles
The third quartile = 150 miles per hour
Hence, the last option is correct

A complete question related to this found on brainly (ID:15577387) is stated below.
Towns K and L are shown on a map.
a) Work out the actual distance
between towns K and L.
b) A third town, M, is 150 km due
South of town K.
Mark M on the map with X.
c) Measure the bearing of town L
from town K.
Scale: 1cm represent 50km
Step-by-step explanation:
Scale: 1cm represent 50km
a) To find the actual distance between towns K and L use a ruler to measure the distance between K and L.
Your answer would be in centimetres (cm).
The answer obtained would be multiplied by 50km because from the scale given 1cm represent 50km.
Therefore you'll get the actual distance in km.
b) Here we are told M is 150 km due
South of town K.
Since the length of the initial diagram is in centimeters, we have to find how many centimeters equals 150km.
50km = 1cm
150km = (150km × 1cm)/50km = 150cm/50
150km = 3cm
Now we can represent the distance between K and M on the diagram.
Measure 3cm from K using a ruler in the direction of south (straight line downwards). The distance of M from K would be 3cm on the south of k.
c) Draw a cross on the position of K. Also draw a cross on the position of L. Connect the distance and measure the angle from K to L. The unit would be in degrees.
From the diagram, the angle is greater than 090° but less than 180°

Answer:
(a) t_n = 3n - 9
(b) t_16 = 39
Step-by-step explanation:
(a)
-3 - (-6) = -3 + 6 = 3
The common difference is 3.
t_1 = -6
t_2 = -6 + 3
t_3 = -6 + 3 + 3
t_4 = -6 + 3 + 3 + 3
t_n = -6 + 3(n - 1)
t_n = -6 + 3n - 3
t_n = -9 + 3n
t_n = 3n - 9
The formula is: t_n = 3n - 9
(b) t_16 = 3(16) - 9 = 48 - 9 = 39
Answer:
an = -6 + 3(n - 1)
a(16) = 39
Step-by-step explanation:
Explicit Formula: an = a1 + d(n - 1)
Our d (common difference) is +3
Our a1 (First term) is -6
To find a(16) (the 16th term), plug in 16 for n.
. Mr. Wayne has a 3-year contract for his cell phone service. He pays $124.65 each month to cover everyone in his family. How much will the cell phone service cost over the 3-year period? Explain your answer
Answer:
$4,523.40
Step-by-step explanation:
The cell phone cost is $124.65 per month. With 12 months in a year, we multiply $124.65 x 12 to get the answer $1,507.80. Since one year equals $1,507.80, we multiply this answer by 3 for 3 years to get $4,523.40. Thus three years of service with $124.65 a month would equal $4,523.40.
Al saves pennies. He agreed to give six thirteenths of his pennies to Bev if she would give six thirteenths of what she got from Al to Carl and if Carl in turn would give six thirteenths of what he got from Bev to Dani. Bev, Carl, and Dani agreed and Dani received 2376 pennies. How many pennies did Al have initially?
Answer:
Step-by-step explanation:
Let x represent the number of pennies that Al had initially.
He agreed to give six thirteenths of his pennies to Bev. It means that the number of pennies that he gave to Bev is 6/13 × x = 6x/13
if she would give six thirteenths of what she got from Al to Carl, it means that the number of pennies that Carl received is 6/13 × 6x/13 = 36x/169
if Carl in turn would give six thirteenths of what he got from Bev to Dani and Dani received 2376 pennies, it means that
6/13 × 36x/169 = 2376
216x/2179 = 2376
216x = 2376 × 2179
216x = 5220072
x = 5220072/216
x = 24167
AI had 24167 pennies initially
Solve for a 7a - 2b = 5a + b
Answer:
a=1.5b
Step-by-step explanation:
Add 2b on both sides to get 7a=5a+3b
Subtract 5a
2a=3b
divide by 2
a=1.5b
ASAP! I do not accept nonsense answers, but BRAINLIEST will be given to the person who gets it correct with full solutions.
Answer:
A
Step-by-step explanation:
The range refers to the possible y-values. You can assume that values on the right column are the y-values if it is not specifically expressed. The right column is the output, or y, column.
Since you have a table, you have to state each number. Put the numbers in numerical order. This gives you an answer of
{46, 49, 52, 53, 58, 63, 64, 67}

find the midpoint of the line segment that has endpoints at (10,8) (-3,-10)
Hey there! :)
Answer:
(3.5, -1).
Step-by-step explanation:
Use the midpoint formula to solve this problem:
[tex](x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
Plug in the coordinates given:
[tex](\frac{10-3}{2}, \frac{8-10}{2})[/tex]
Simplify:
[tex](\frac{7}{2}, \frac{-2}{2})[/tex]
Therefore, the coordinates of the mid-point are:
(3.5, -1).
