(3x2 – 5x + 3) and (-x2 – 3x)
Answer:
2x² - 8x + 3
Step-by-step explanation:
( 3x² - 5x +3) + (-x² - 3x)
= 3x² - 5x +3 - x² - 3x
= 3x² - x² - 5x - 3x + 3
= 2x² - 8x + 3
Write 65/22 as a decimal. If necessary, use a bar to indicate which digit or group of digits repeats.
Answer:
2.954545454
Step-by-step explanation:
65/22 = 65 divided by 22. That is how many times 22 can go into 65
A decimal number has a decimal point in it. That is a whole number and some fraction that could be in tenths or otherwise.
65 is the numerator,
22 is the denominator
Using a calculator
65/22 = 2.9545454

Joe is 72 inches tall and has a 108 inch shadow at the same time martha has a 96 inch shadow how tall is martha
Answer:
64 inches
Step-by-step explanation:
Given :
(Joe's height / Joe's shadow) = (Martha's height / Martha's shadow)
Let Martha's height = h
72 in / 108 in = h / 96 in
Cross multiply :
108 * h = 72 * 96
h = (72 * 96) / 108
h = 6912 / 108
h = 64 inches
Martha is 64 inches tall.
A submarine submerges at the rate of 5min. if it descends from 20 m above the sea level :What will be the total depth it submerged if it is to reach 250m below sea?
Answer:
Submarine submerges at the rate of =5m/min
descend starts from = 20m
submarine have to reach = -250m
Distance between above sea level to below sea level = 250 + 20 = 270m
time taken to reach 270 m = 270/5= 54 minutes

Identify the outlier in the data set, and determine how the outlier affects the mean, median, and mode of the data. Then tell which measure of central tendency best describes the data with and without the outlier. Justify your answer. 85, 91, 83, 78, 79, 64, 81, 97
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
85, 91, 83, 78, 79, 64, 81, 97
Ordered data : 78, 79, 81, 83, 85, 91, 97
Mean:
Σx / n =
n = sample size = 8
(64+78+79+81+83+85+91+97) / 8
= 658 / 8
= 82.25
Median = 1/2(n+1)th term
1/2(8+1)th term = 1/2 * 9 = 4.5th term
(4th term + 5th term) /2 = (81 + 83) / 2 = 82
Mode = 85, 91, 83, 78, 79, 64, 81, 97
Outlier:
Lower = Q1 - 1.5(IQR)
Upper = Q3 + 1.5(IQR)
Using a calculator :
Q1 = 78.5 ; Q3 = 88 ;
IQR = (Q3 - Q1)
(88 - 78.5) = 9.5
Outlier :
78.5 - 1.5(9.5) = values < 64.25
88 + 1.5(9.5) = values > 102.5
Hence. Outlier is 64
Removing the Outlier :
Data = 78, 79, 81, 83, 85, 91, 97
Mean = 84.85
Median = 83
Based on the result, the median is the best measure of central tendency for the data:
2⁄7 · n = 4 what is the answer
Answer: the answer is 14 if the 2 and 7 are a fraction and if it’s just 27xn=4 the answer is 4/27 and in decimal form it’s 0.148
Step-by-step explanation:
Answer: n=14
First, multiply 2/7xn which is 2n/7=4
Next, multiply both sides by 7 to get the 2n on one side by its self (2n=28)
Then divide 28 by 2 which gives you n=14

A surveyor measures a road as being 69.3km long, however there is a 1℅ error in this measurement .What is the true length of the road
Answer:
69.993
Step-by-step explanation:
Using the percentage error formula:
Percentage error = (true - measured value / true measurement ) * 100%
1% error in measurement
1% of 69.3
0.01 * 69.3 = 0.693
True measurement = error in measurement + measured value
True measurement = 0.693 + 69.3
Actual measurement = 69.993
Hence, actual measurement = 69.993.

14
56
644
698
The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.
What is the expected value?In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.
The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces.
Then the probability of the oranges that weigh 5 ounces is given as,
p = 2/25
Then the number of oranges in the shipment can the manager predicts weigh 5 ounces will be given as,
E(x) = 700 x 2 / 25
E(x) = 28 x 2
E(x) = 56
The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

What is the degree measure of ∠FEG ?
. A triangle has side lengths of 8, 7, and 14. To the nearest tenth of a degree find the measure of the angle opposite the side of length 8.
Given:
The measure of three sides of a triangle are 8, 7 and 14.
To find:
The measure of the angle opposite the side of length 8.
Solution:
According to the Law of Cosine:
[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]
Let a=8, b=7 and c=14, then by using Law of Cosine, we get
[tex]\cos A=\dfrac{7^2+14^2-8^2}{2(7)(14)}[/tex]
[tex]\cos A=\dfrac{49+196-64}{196}[/tex]
[tex]\cos A=\dfrac{181}{196}[/tex]
Taking cos inverse on both sides.
[tex]A=\cos^{-1}\dfrac{181}{196}[/tex]
[tex]A=22.561328[/tex]
[tex]A\approx 22.6[/tex]
Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.

(cscB/cotB)=
Answer:
This would equal sec (B)
Step-by-step explanation:
find the area of the triangle
The area of the triangle is:
[tex]\Large\displaystyle\text{$\begin{aligned}A\triangle &= \dfrac{21+7\sqrt{15}}{2}\\ \\A\triangle &\approx 24.055\\ \\\end{aligned}$}[/tex]
You can easily find the area of a triangle using the formula:
[tex]\Large\displaystyle\text{$\begin{aligned}A\triangle = \dfrac{bh}{2}\end{aligned}$}[/tex]
Where h is the height of the triangle, and b the base.
Looking at the figure we can see that h = 7, but we need to discover the base, we know that the base is:
[tex]\Large\displaystyle\text{$\begin{aligned}b = 3 + x\end{aligned}$}[/tex]
Where:
[tex]\Large\displaystyle\text{$\begin{aligned}8^2 &= x^2 + 7^2\\ \\x^2 &= 8^2 - 7^2 \\ \\x^2 &= 64 - 49\\ \\x^2 &= 15\\ \\x &= \sqrt{15}\end{aligned}$}[/tex]
Therefore, our base length is:
[tex]\Large\displaystyle\text{$\begin{aligned}b &= 3 + x\\ \\b &= 3 + \sqrt{15}\\ \\\end{aligned}$}[/tex]
Then we can just apply the formula for the area:
[tex]\Large\displaystyle\text{$\begin{aligned}A\triangle &= \dfrac{(3+\sqrt{15})\cdot 7}{2}\\ \\A\triangle &= \dfrac{21+7\sqrt{15}}{2}\\ \\A\triangle &\approx 24.055\\ \\\end{aligned}$}[/tex]

Bill mixes candy costing 45cents per pound with candy costing 65cents a pound. A 7-pound box of the mix costs $3.65. How much of each kind of candy should Bill use?
Answer:
Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.
Step-by-step explanation:
With the information provided, you can say that the sum of the pounds of each type of candy is equal to 7, which can be expressed as:
x+y=7
Also, the statement indicates the 7 pound box costs $3.65 and you can say that the sum of the results of multiplying the price of each candy for the number of pounds is equal to $3.65, which is:
0.45x+0.65y=3.65
You have the following equations:
x+y=7 (1)
0.45x+0.65y=3.65 (2)
Now, you have to solve for x in (1):
x=7-y (3)
Then, you have to replace (3) in (2):
0.45(7-y)+0.65y=3.65
3.15-0.45y+0.65y=3.65
0.20y=0.50
y=0.50/0.20
y=2.5
Finally, you can replace the value of y in (3) to find x:
x=7-y
x=7-2.5
x=4.5
According to this, the answer is that Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.
