Answer:

The upper left answer.

Step-by-step explanation:

Using the box diagrams and the given data, the ranges for both the radios can be calculated by subtracting the minimum from the maximum of each data set:

<u>Secure hike Emergency Radio 4.0</u>

Range = 33-21=12

<u>Xtreme Crank Radio</u>

Range = 42 -25

The range of the Xtreme Crank Radio is bigger than the other radio, which means that the data is more spread out, making it less consistent..

The data also shows a lot more entries for the Xtreme Crank Radio that are 30 and above, whereas the secure radio has only a few.

Therefore, the top left answer describes the data best.

To get the statement that closely describes the sample results we proceed as follows:
X-trimeline
lowest value=21
lower quartile=25
median=26
upper quartile=30
highest value=33
range=33-21=12
Radio 4
lowest value=25
lower quartile=27
median=30
upper quartile=36
highest value=42
Range=42-25=17

From the above we conclude that the Answer is: Option A

6 inch pizza has 570 calories how many calories in a 14 inch pizza

ki77a [65]

First, let's find the amount of calories in a 1 inch pizza:

570/6=95

Knowing this, we just multiply the calorie count of a one inch pizza by 14 to find the calorie count of a 14 inch pizza:

14*95=1330

There are 1330 calories in a 14 inch pizza.

A bike rental is $20 for a day and $3 for an hour. Caroline rented a bike for 2 days and 2 hours. Write and equation you could u

wolverine [178]

Answer:

M = 20(2) + 3(2) = $46

Step-by-step explanation:

Here, we want to write an equation that could be used to find the amount of money spent

The rental charges $20 for a day and $3 for an hour

For 2 days, amount is 2 * 20 = $40

for 2 hours , amount is 3 * 2 = $6 hours

The amount Spent M will be;

M = 20(2) + 3(2) = $46

The sum of two consecutive numbers is at least 46. What is the least possible pair of integers?

Lady bird [3.3K]

x + (x+1) >=46

2x+1 >=46

subtract 1 from each side

2x >= 45

divide by 2

x>= 22.5

x =23

x+1 =24

The two integers are 23 and 24

Eight times a number plus five another number is -13. The sum of the two numbers is 1. What are the numbers?

Pani-rosa [81]

Eight *(a number) plus 5*(another number) is -13.

translates to:

8(x) + 5(y) = -13

The sum of (the number) and (the other number) is 1.

translates to:

(x) + (y) = 1

We have a system of two equations involving two unknowns: x and y.

$\rm 8x+5y=-13\\
~~x+~~y=~~~~1$

We can easily solve the system using Substitution or Elimination. Let's use Elimination this time.

We'll multiply the second equation by -8 so that the x's match up.

$\rm ~~~8x+5y=-13\\ -8x-8y=-8$

When we add the equations together, the x's will fall out of the equation, summing to zero. The 5y and -8y will sum to -3y and the right hand side will sum to -21.

$\rm -3y=-21$

Divide by -3,

$\rm y=7$

Plug back into one of your original equations to find the value of x,

$\rm x+y=1\\
x+7=1$

Subtract 7,

$\rm x=-6$
