Carly paid $17.50 for 7 gallons of gas and Jade paid $45 for 15 gallons of gas. Which of the following statements is true?

1 answer:

6 0

First we have to find how much they spent on each gallon.
To find out how much Carly paid for each gallon we have to divide her total price by haw many gallons she got.
$17.50/7=$2.50 per gallon
Likewise we do the same for Jade
$45/15=$3

So the answer will be Jade paid more per gallon than Carly

Divide. Then check your answer using multiplication. Use paper to show you work. 745/82 Quotient=. Remainder=

Irina-Kira [14]

Answer:

Quotient = 9

Remainder = 7

Step-by-step explanation:

Divide :

745 / 82

= 9 ; (82 * 9 = 738)

Remainder = 745 - 738) = 7

Hence to verify :

(82 * 9) + 7

738 + 7

= 745

Using direct division :

745 / 82 = 9.0853658

Suppose we want to test the color distribution claim on the M&M’s website that a bag of plain M&M’s is made up of 10% bl

Ugo [173]

Answer:

Calculated χ² = 13.425

χ² (5,0.025) >14.45 and χ²(5,0.975) <1.24

The given data does not fall in the critical region so we accept H0 and conclude there is no evidence to doubt the color distribution claimed by the website.

Step-by-step explanation:

Color Blue Orange Green Red Yellow Brown

Frequency 30 48 55 66 70 131

Expected 40 40 40 80 80 120

H0: The bag of plain M&Ms is made up of 10% blue, 10% orange, 10% green, 20% red, 20% yellow, and 30% brown

Ha: The color distribution is not equal to the distribution stated in the null hypothesis.

Calculate chi square

χ² = (30-40)² /40 + (48-40)²/40 + (55-40)²/40 + (66-80)²/80 + (70-80)²/80 + (131-120)²/120

χ² = 2.5 + 1.6 + 5.625 + 2.45 + 1.25= 13.425

The critical region for χ² for 5 degrees of freedom with ∝= 0.05 is

χ² (5,0.025) >14.45 and χ²(5,0.975) <1.24

The given data does not fall in the critical region so we accept H0 and conclude there is no evidence to doubt the color distribution claimed by the website.

The Surface are of a cylinder is 325 inches. The Lateral area is 200 in. What is radius of each base?

AleksAgata [21]

Answer:

The radius of each base is 4.46 inches.

Step-by-step explanation:

The surface area (SA) of a cylinder is given by:

$SA = 2\pi rh + 2\pi r^{2} = 325$ (1)

Where:

r: is the radius of each base

h: is the height of the cylinder

Now, the lateral area (LA) is:

$LA = 2\pi rh = 200$ (2)

Hence, by entering equation (2) into equation (1) we have:

$SA = LA + 2\pi r^{2}$

$325 = 200 + 2\pi r^{2}$

$r = \sqrt{\frac{325 - 200}{2\pi}} = 4.46 in$

Therefore, the radius of each base is 4.46 inches.

I hope it helps you!

the parameters of a linear function are the slope and the y-intercept a cab company's far can be modeled with the linear functio

Len [333]

Answer:

see the explanation

Step-by-step explanation:

we know that

A linear function in slope intercept form is equal to

$f(x)=mx+b$

where

m is the slope or unit rate

b is the y-intercept

x is the independent variable or input value

f(x) is the dependent variable or output value

In this problem we have

$f(m)=5+3m$

where

m is the number of miles

f(m) is the cab company's fare in dollars

we have that

In this context

<em>Slope</em>

The slope or unit rate is equal to the cost per mile for the riders trip

The slope is $3 per mile

<em>Y-intercept</em>

The y-intercept is the cost of the riders trip when the number of miles is equal to zero, also is called the initial value.

The y-intercept is $5
