1) Mr. Rios bought a house in 1960 for $20,000. The value of the house increased by
approximately 5% each year. Which of the following equations will give the value, A, the
approximate value of the house after x years?
A- A = 20000(0.5)*
B- A = 20000(1.5)
C- A = 20000(0.05)
D- A = 20000(1.05)*
Answer:
A = 20,000(1.05)^x
Step-by-step explanation:
To get the approximate value of the house after x years, we will use the compound interest formula
A = P(1+r)^n
P is the principal = $20,000 (cost of house)
r is the rate = 5% = 0.05
x is the time
Substitute into the expressio
A = 20,000(1+0.05)^x
A = 20,000(1.05)^x
Hence the required expression is A = 20,000(1.05)^x
The sum of 42 and x is equal to 97.45. What's the equation for the sentence?!! Help!
Answer:
X = 97.45 - 42
Step-by-step explanation:
If 42 + X = 97.45, X needs to be 97.45 - 42
you can do the same thing with smaller numbers, for example:
5 + X = 7
7 - 5= 2 and you can check for sure that this is the answer by adding them together 5 + 2= 7 so it's definitely the right answer
so for this question, 97.45- 42 = 55.45 so that's X
you can check that by 55.45 + 42 and if the answer is 97.45 that's the right answer!
I hope that makes sense
Find how many quarts of 5% butterfat milk and 2% butterfat milk should be mixed to yield 45 quarts of 3% butterfat milk.
The mixture should contain quarts of the 5% butterfat milk.
Answer:
It would take 4 quarts of 5% buttermilk and 41 quarts of 2% buttermilk to make 45 quarts of 3% buttermilk.
Step-by-step explanation:
Let the number of 5% quarts = x
Let the number of 2% quarts = y
x+y=45
y=45-x
(.05)x+(.02)y=(0.03)45
5x+2y=102
5x+2(45-x)=102
5x+90-2x=102
3x=12
x=4
y=45-x=45-4=41
So it would take 4 quarts of 5% buttermilk and 41 quarts of 2% buttermilk to make 45 quarts of 3% buttermilk.

Assume that you have obtained a sample mean of 56 Pa, a test statistic of -2.02 and a p-value of 0.095. Which of the statements below are correct interpretations of the p-value?
a. There is a 9.5% chance of making a mistake by rejecting the null hypothesis of the mean elasticity being as per design specification.
b. Assuming the mean elasticity is as per design specification, the probability of observing a sample mean as small or smaller than 56 Pa is 0.095.
c. Assuming the mean elasticity is as per design specification, the probability of observing a sample mean as large or larger than 56 Pa is 0.095.
d. Assuming the mean elasticity is as per design specification, the probability of obtaining a test statistic as small or smaller than -2.02 is 0.095.
e. Assuming the mean elasticity is as per design specification, the probability of obtaining a test statistic as large or larger than -2.02 is 0.095.
f. There is a 0.095 probability that the results are due to chance.
g. None of the above.
Answer:
options : B and D
Step-by-step explanation:
Given that the sample mean = 56 pa , test statistic = -2.02 and the p-value = 0.095 . the correct statements about the interpretations of the p- value are :
Assuming the mean elasticity is as per design specification, the probability of observing a sample mean as small or smaller than 56 Pa is 0.095. Assuming the mean elasticity is as per design specification, the probability of obtaining a test statistic as small or smaller than -2.02 is 0.095.PLEASE HELP ME ASAP WITH WORK!!

How many times larger than
(8 + 22) is 8 x (8 + 22)?
Answer:
8
Step-by-step explanation:
8+22 = 30
In order to solve 8 • (8+22), we'll need to use the order of operations. First, complete what is in parenthesis.
8 • (8+22)
30
Then, multiply 30 by 8.
30 • 8 = 240.
So, you can then divide to find your answer. If you divide 240 by 30, you will find that 8 • (8+22) is 8 times larger than 8+22.
Answer:
8 times larger

Mark went to the bookstore. He bought 3
books for $6.00 each and two magazines
for $3.50 each. He received a 25% discount
on his purchase. If he handed the cashier
$20, how much change did Mark get back?
Answer: $1.25
Step-by-step explanation: (6*3) = 18 + (2*3.50)= 7
18+7=25
25*.25= 6.25
25-6.25= 18.75
20-18.75 = 1.25

Jean's bedroom is 10 feet by 12 feet. She has chosen a carpet which costs $31.35 per square yard. This includes
installation
Determine her cost to carpet her room.
PLEASE NO LINKS, thanks
Answer:
416.67$
Step-by-step explanation:
First, the units of the price are using square yards. To simplify early, we can convert the sides to yards.
Bedroom dimensions: 10/3 yards by 4 yards.
Since the cost is by area unit, we can find the area by multiplying the dimensions(assuming the bedroom is a square), yielding us 40/3 square yards.
Now multiplying the square yards by the price gets us:
[tex]\frac{40}{3}yards^{2} * 31.35 * 1/yards^2 =[/tex]416.67$
