Answers
Answer:
x = -4
Step 1: Take all the constants on one side and the variables on the other.
(2 × x) + 12 = 4
=> (2 × x) = 4 - 12
(2 × x) = -8
Step 2: Divide 2 both sides to isolate 'x'.
=> [tex]\frac{2x}{2}[/tex] = [tex]\frac{-8}{2}[/tex]
=> x = -4

1: 0.625, 2: 1.05, 3: 2 13/20
Step-by-step explanation:
Use a calculator to determine the exact value of the fractions, or do it by hand.
Answer:
0.625 , 1.05, 2 13/20
Step-by-step explanation:
Well, this isn't that hard if you really think about it.
For Number 1: 5/8 as a decimal, first you want to divide
100 by 8, which equals to 12.5. Then multiply 12.5 by 5 which gets you 62.5
Move the decimal place 2 to the left, and you get 0.0625.
For Number 2: 1 and 1/20
100/20=5
So you have 1 and 5/100, convert 5 to percent so 5%
5%+100%=105%
105= 1.05
Number 3: 2.65
100/20=5
13x5=65
0.65+2= 2.65, 2 13/20.

Step-by-step explanation: 1.Likewise, a number is a reversible multiple if the number formed by 2058 is not reversible because 8502/2058 = 4.131, which is not a whole number
2. When rabbits eat carrots you cannot form the carrot back to its original form so that's why its irreversible (not/non revisable)
3.If two perpendicular lines intersect, they form four 90* angles. ... whose sum measures to 90 degrees - The statement is not reversible

Tony and Ricky spend a certain amount of money from their accounts each week at a pet shelter.
The table shows the relationship between the amount of money (y) remaining in Tony's account and the number of weeks (x):
Function 1:
Number of Weeks
(x) Amount Remaining (dollars)
(y)
1 30
2 24
3 18
4 12
The equation shows the relationship between the amount of money, y, remaining in Ricky's account and the number of weeks, x:
Function 2:
y = –7x + 30
Which statement states and explains which function shows a greater rate of change?
Function 1, because Tony spends $6 each week and Ricky spends –$7 each week
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Function 1, because Tony spends $18 each week and Ricky spends $23 each week
Function 2, because Ricky spends $30 each week and Tony spends $18 each week
Answers
Answer:
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Step-by-step explanation:
You find the rate of weekly rate of change by calculating the difference of the amount changing each week:
24 - 30 = - 6
18 - 24 = - 6
12 - 18 = - 6
As you see the rate of change is constant: - 6 dollars per week. This means that Tony is spending 6 dollars every week
Function 2: y = –7x + 30
The rate of change is the slope (m) of the linear function, and this is the coefficient of the independent variable, x.
This equation is written in slope intercept form (y= mx+b)
Then the rate of change is - 7 dollar per week. This means Ricky spends 7 dollars every week.
Now you know that the two rates are constant and that the second function shows a steeper decreasing.

Clothing sizes are not standardized across brands. Suppose that a large study of women's size 14 jeans revealed that the mean hip measurment was 42.3 in with a standard deviation of 1.2 in. As part of a project for a fashion merchandizing class, Mallorie selects a simple random sample of 15 pairs of women's size 16 jeans and records the following hip measurements. in inches. 44.5,43.0, 46.6, 42.9.43.7.43.9.42.4, 43.2, 43.1.44.4.46.1, 44.7,44.4, 43.9,44.7 Mallorie plans to use this data to construct a 99% confidence interval for fe, the mean hip measurement of women's size 16 jeans. She assumes that the hip measurements are normally distributed and that the population standard deviation is 1.2 in. The sample mean, x, is the point estimate for a confidence interval to estimate a population mean. What is the mean hip measurement for the random sample of 15 pairs of women's size 16 jeans? What is the margin of error for Mallorie's confidence interval? Choose the correct interpretation of Mallorie's confidence interval. a. Mallorie is 99% sure that the mean hip measurement of size 8 jeans is between 37.71 in and 38.67 in. b. In 99% of all samples, the sample mean will fall between 37.66 in and 38.73 in. c. There is a 99% chance that the mean hip measurement of size 8 jeans falls between 37.71 in and 38.67 in. d. There is a 99% chance that the mean hip measurement of size 8 jeans falls between 37.66 in and 38.73 in. e. Mallorie is 99% sure that the mean hip measurement of size 8 jeans is between 37.66 in and 38.73 in.
Answers
Using the z-distribution, we have that:
The mean hip measurement for the random sample of 15 pairs of women's size 16 jeans is of 44.1 inches.The margin of error is of 0.8 in.The interpretation is: Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.The first step to solve this question, before building the confidence interval, is finding the sample mean, which is the sum of all observations divided by the number of observations. Hence:
[tex]\overline{x} = \frac{44.5+43.0+46.6+42.9+43.7+43.9+42.4+43.2+43.1+44.4+46.1+44.7+44.4+43.9+44.7}{15} = 44.1[/tex]
The margin of error of a z-confidence interval is given by:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
z is the critical value. [tex]\sigma[/tex] is the population standard deviation. n is the sample size.We have to find the critical value, which is z with a p-value of [tex]\frac{1 + \alpha}{2}[/tex], in which [tex]\alpha[/tex] is the confidence level.
In this problem, [tex]\alpha = 0.99[/tex], thus, z with a p-value of [tex]\frac{1 + 0.99}{2} = 0.995[/tex], which means that it is z = 2.575.
Then, the margin of error is:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 2.575\frac{1.2}{\sqrt{15}}[/tex]
[tex]M = 0.8[/tex]
The margin of error is of 0.8 in.
The interval is:
[tex]\overline{x} \pm M[/tex]
[tex]\overline{x} - M = 44.1 - 0.8 = 43.3[/tex]
[tex]\overline{x} + M = 44.1 + 0.8 = 44.9[/tex]
The interpretation is:
Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

Manassas Park is selling tickets for their fall musical. On the first day of sales, we sold 3

8 adult tickets and 5 student tickets and made $67. How much does an adult and a
student ticket cost?
Answers
Answer:
Adult: $ 4
Student: $ 7
Step-by-step explanation:
Adult: x
Students: y
a) 3x + 9y = 75
b) 8x + 5y = 67
Substitution:
a) 3x = -9y + 75
x = (-9y + 75)/3
x = -3y + 25
Substitute:
b) 8(-3y+25) + 5y = 67
-24y + 209 + 5y = 67
-19y = -209 +67
y = -133/-19
y = 7
Substitute:
x = = 3(7) + 25
x = -21+25
x = 4
