Angelica wants a cell phone, but her parents have told her that she has to pay for the bill and the phone. The phone that she wants is
$
100
, and her part of the service plan would be
$
35
each month.

Which function represents the cost of Angelica’s cell phone based on the number of months she uses the phone (
x
)?

Answer:

  z ≈ -0.92

Step-by-step explanation:

Put the numbers in place of the corresponding variables and do the arithmetic.

  [tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{pq}{n}}}=\dfrac{\dfrac{495}{1708}-0.30}{\sqrt{\dfrac{0.30(1-0.30)}{1708}}}=\dfrac{495-0.30(1708)}{\sqrt{1708(0.30)(0.70)}}=\dfrac{-17.4}{\sqrt{358.68}}\\\\\boxed{z\approx -0.92}[/tex]

Answer:

y = -4x + 12

Step-by-step explanation:

-8x - 2y = -24

Add '2x' to both sides

  -2y = 8x - 24

Divide the entire equation by (-2)

[tex]\dfrac{-2y}{-2}=\dfrac{8x}{-2}-\dfrac{24}{-2}\\\\[/tex]

y = -4x + 12

Answer:

3

Step-by-step explanation:

if you put 3 into the numerator you can evaluate the equation.

by placing 3 in the numerator, you can then create a common denominator (20) which also changes the value of 3 to 12.

12 + 18 =30

Answer:

$300 is the total cost for both kinds of paint

Step-by-step explanation:

1) Start by breaking down the problem so it was more simple

- Red paint is $35 per gallon; blue is $39 per gallon

2) Since it is by gallon, you will multiply the number of gallons by the cost for each to get the total cost of each

- 35 * 3 = $105 for 3 gallons of red paint

- 39 * 5 = $195 for 5 gallons of blue paint

3) Total cost together; you will add the total cost of red and blue paint together

- 105 + 195 = $300

Answer:

927.3 feet per hour

Step-by-step explanation:

first determine how many seconds are in one hour

there are 60 seconds in one minute and 60 minutes in one hour

so there are 60x60, or 3600 seconds in one hour

now you can create a proportion of inches/seconds = inches/seconds

let 'x' = inches per hour

34/11 = x/3600

cross-multiply to get:

11x = 3600x34

11x = 122,400

x = 122,400/11

x = 11,127.3 inches per hour

to determine how many feet per hour you must divide 11,127.3 inches by 12

this equals 927.3 feet per hour

2x2+3x=52358592020394883

Answer: reject the null hypothesis

Explanation:

If the p-value is smaller than the significance level alpha, then we reject the null. You can think of the p-value being the probability that the null is correct. If the p-value is below a certain threshold (the significance level), then we can be fairly confident that rejecting the null is a good decision.

Your teacher or textbook might have brought up the phrase "If the p-value is low, then the null must go" as a way to help remember this rule. If the alpha level isn't stated, then usually it defaults to 0.05

Answer:

y = 2/3x + 2

Step-by-step explanation:

3x + 2y = 8

2y = -3x + 8

y = -3/2x + 4

Slope : -3/2

Slope of the perpendicular line: 2/3 (slope of the perpendicular line is opposite reciprocal)

Point (3,4)

y-intercept = 4 - (2/3)(3) = 4 - 2 = 2

Answer:

Answer:

m - a - b  =   c

Step-by-step explanation:

m    =   a + b + c                      

  -a  =  -a                Add -a from both sides

m - a     =    b + c

       -b  =   -b         Add -b from both sides

m - a - b =   c
