Zach's parents put $1,500 in her bank account for college tuition. At an interest rate of
8.25% compounded weekly, what will be the balance after 18 years? (Make sure you
answer is in dollars and rounded to 2 decimal places)
Answer:
After 18 years, Zach's account balance will be $ 6,614.66.
Step-by-step explanation:
Given that Zach's parents put $ 1,500 in her bank account for college tuition at an interest rate of 8.25% compounded weekly, to determine what will be the balance after 18 years the following calculation must be performed:
1,500 x (1 + 0.0825 / 52) ^ 18x52 = X
1,500 x 1.00158653 ^ 936 = X
6,614.66 = X
Therefore, after 18 years, Zach's account balance will be $ 6,614.66.
After the tour, Tyler’s mom bought a pretzel and a bottle of water for each family member. The bottles of water cost $1.50 each. If she paid a total of $30, how much did each pretzel cost? There were 5 family members
Answer:
4.50
Step-by-step explanation:
water + pretzels =total
5(1.50)+ 5x =30
7.50+5x=30
5x=22.50
x=4.50

A clear file box shaped like a rectangular prism is modeled below. The shaded part represents one base of the box. A formula for finding the volume of a rectangular prism is V = Bh. Which equation can be used to find B, the area of the shaded base of the box in square inches? (A) B = 1/2(19)(14) (B) B = 19 + 14 (C) B = (19)(14) (D) B = 2(19) + 2(14)
Answer:
C. B = (19)(14)
Step-by-step explanation:
Given:
length (l) = 19 in.
width (w) = 14 in.
height (h) = 11 in.
Formula for volume of the rectangular prism = Bh
Base area (B) = l*w
Base area (B) = (19)(14) in.²
Formula for finding base area: B = (19)(14)

There are 3 apples, 4 oranges and 1 pear in a bag. Find each probability
1) Select an orange and then a pear(without replacement)
2)You select an orange then an apple then a pear without replacement
3)You select an Apple, then an orange, then another apple without replacement
Help please
Answer:
8 fruit total
1) orange probability: 4/8 = 1/2
pear probability after one fruit is taken out: 1/7
probability of getting one then the other without replacement: 1/2 x 1/7 = 1/14
2) orange: 1/2
apple: 3/7
pear: 1/6
probability of getting them in order without replacement: 1/2 x 3/7 x 1/6 = 1/28
3) apple: 3/8
orange: 4/7
apple: 2/6 = 1/3
probability of getting them in order without replacement: 3/8 x 4/7 x 1/3 = 1/14
Answer:2/6 or 33% chance of getting an apple, 3/24 or 13% of getting a pear and 13/24 or 54% chance of getting an orange hope that helps.

Consider a sample with data values of 27, 25, 20, 15, 30, 34, 28, and 25. Compute the range, interquartile range, variance, and standard deviation (to a maximum of 2 decimals, if decimals are necessary).
Range:
Interquartile range:
Variance:
Standard deviation:
Range: 19
Interquartile range: 6.5
Variance: 44.86
Standard deviation: 6.70
Step-by-step explanation:
Given set:
27, 25, 20, 15, 30, 34, 28, 25.
(i) Range is the difference between the largest value and smallest value in a given data.
In the data above, the;
largest value = 34
smallest value = 15
Range = largest - smallest
Range = 34 - 15
Range = 19
(ii) Interquartile range is the difference between the median (Q₁) of the lower half of the given data, and the median (Q₃) of the upper half of the given data. i.e Q₃ - Q₁.
This should be done after ordering the given data in ascending order.
Ordering the above data gives:
15, 20, 25, 25, 27, 28, 30, 34
In the data above;
lower half = 15, 20, 25, 25
upper half = 27, 28, 30, 34
Find median (Q₁) of the lower half
Since there are even number of data, the median is the average of two middle numbers (20 and 25) i.e.
Q₁ = [tex]\frac{20+25}{2}[/tex] = [tex]\frac{45}{2}[/tex] = 22.5
Find median (Q₃) of the upper half
Since there are even number of data, the median is the average of two middle numbers (28 and 30) i.e.
Q₃ = [tex]\frac{28+30}{2}[/tex] = [tex]\frac{58}{2}[/tex] = 29
Interquartile range = Q₃ - Q₁
Interquartile range = 29 - 22.5
Interquartile range = 6.5
(iii) Variance is the measure of variability of a given set of data. It is calculated by following these steps:
=> First find the mean of the data by summing the numbers and dividing by the number of numbers. i.e
mean(x) = [15 + 20 + 25 + 25 + 27 + 28 + 30 + 34] / 8
mean(x) = [204] / 8
mean(x) = 25.5
=> Next, get the mean deviation by subtracting the mean from each individual value in the given set of data. i.e
15 - 22.5 = -7.5
20 - 22.5 = -2.5
25 - 22.5 = 2.5
25 - 22.5 = 2.5
27 - 22.5 = 4.5
28 - 22.5 = 5.5
30 - 22.5 = 7.5
34 - 22.5 = 11.5
=> Next, find the square of each of the results obtained above. i.e
(-7.5)² = 56.25
(-2.5)² = 6.25
(2.5)² = 6.25
(2.5)² = 6.25
(4.5)² = 20.25
(5.5)² = 30.25
(7.5)² = 56.25
(11.5)² = 132.25
=> Next, add all the results above together as follows;
56.25 + 6.25 + 6.25 + 6.25 + 20.25 + 30.25 + 56.25 + 132.25 = 314
=> Now, obtain the variance by dividing the result above one less than the number of numbers.
The number of numbers is 8. One less than this gives 7.
Therefore,
Variance = 314 / 7
Variance = 44.86
(iv) Standard deviation is the measure of how the numbers in the given data are spread out. It is calculated as the square root of variance.
Therefore,
Standard deviation = √variance.
Variance has been calculated above.
Standard deviation = √44.86
Standard deviation = 6.70

Step-by-step explanation:
800x.6x.5x8.95=2,148
800x.2x.3x8.95=429.6
800x.2x8.95=1,432
2148+429.6+1432=4009.6

A bag of marbles has 10 red marbles, 4 green marbles, and 6 blue marbles. A marble is randomly drawn from the bag before another marble is drawn, without replacement. What is the probability that a green marble and then a red marble are selected? Enter your answer as a fraction in simplest form in the box
Answer:
Step-by-step explanation:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.
Can someone answer this please
Answer:
<COB = 50°
Step-by-step explanation:
We can say that m<AOC + m<COD + m<DOB = 180° because the three mentioned angles form a straight line. We can substitute to get:
3x + 94 + x + 18 + 2x - 4 = 180
Then, we can combine like terms:
6x + 108 = 180
6x = 72
x = 12
We can see that m<COB is the sum of m<COD and m<DOB. We can wrote an equation to model the situation:
m<COB = m<COD + m<DOB
m<COB = x + 18 + 2x - 4
m<COB = 3x + 14
We have the value of x, so we can substitute that in:
<COB = 3(12) + 14
<COB = 36 + 14
<COB = 50°

Juliet coaches softball and soccer. she coaches both sports for 15 hours each day. soccer practice is 1.5 more hours more than 3 times as long as the softball practice. write a system of equations to model the situation.
Answer: See explanation
Step-by-step explanation:
Let the number of hours used for softball practice be x.
Since soccer practice is 1.5 more hours more than 3 times as long as the softball practice. This will be:
= (3 × x) + 1.5 = 3x + 1.5
Therefore, we add both and equate to 15.
x + 3x + 1.5 = 15
4x + 1.5 = 15
4x = 15 - 1.5
4x = 13.5
x = 13.5/4
x = 3.375
Softball is practiced for 3.375 hours
at the end of a party there was one half pizza left over seven friends decided to divide the pizza equally. what fraction of the whole pizza did each friend have?
Answer:
Each friend only got 1/14 of the pizza.
Step-by-step explanation:
Each friend gets one slice of pizza, and there are 7, so you'd think just do 1/7 and that is the answer. However, it is talking about after the party where only have of the pizza is left. So you have to do 1/7*1/2 which equals 1/14.
Emilie can complete a job in 10 minutes, while Erica can complete the same job in 15 minutes. How long would it take them to complete the job working together? (In minutes.) Rate of work problem.
9514 1404 393
Answer:
6 minutes
Step-by-step explanation:
The rates add when expressed in terms of jobs per minute.
1/10 + 1/15 = 3/30 + 2/30 = 5/30 = 1/6
The two together can complete 1/6 jobs per minute, so it will take them 6 minutes to complete 1 job.

answer 40qfijjjjjmwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwStep-by-step explanation:
the sum of 2 numbers is 18 while the product is -63. find the numbers.
Answer:
Step-by-step explanation:
let the numbers be x and y,then
x+y=18
x=18-y
also xy=-63
(18-y)y=-63
18y-y²=-63
y²-18y-63=0
y²-21y+3y-63=0
y(y-21)+3(y-21)=0
(y-21)(y+3)=0
y=21,-3
when y=21
x=18-21=-3
when y=-3
x=18-(-3)=18+3=21
so numbers are -3 and 21.
