Select the correct answer.
Energized and Powercell are companies that manufacture alkaline batteries. Both companies claim that their batteries last longer than the average alkaline battery.

Anju decided to conduct a test to see whether their claims were true. He purchased 30 Energized batteries, 30 Powercell batteries, and batteries of other brands to conduct the test. The purchase selection was random, and the test was unbiased. The batteries that lasted longer than the average of all the batteries were stated to have passed the test. The batteries that did not last as long as the average of all the batteries were stated to have failed the test. The results for Energized and Powercell are displayed in this table.

Answer:

45 cm²

Step-by-step explanation:

Area of polygon = Area of square + (area of triangle)

= (side * side) + (1 / 2 * bh)

= 5*5 + (1 / 2 * 5 * 8)

= 25 + (20)

= 25 + 20

= 45 cm²

Answer:

70

Step-by-step explanation:

Let the claire pointa be x then

Mean = Sameson X / N

40= 20+30+x/3

40×3=50+x

120-50=x

Therefore x=70

Answer:

A) 3 cm

Step-by-step explanation:

since length x width = area, divide the area by the length. 30/10 = 3 (the width.)

Answer:

$ 63,250

Step-by-step explanation:

55,000 x 0.15 = 8,250

55,000 + 8,250 = 63,250

Answer:

$63,250

Step-by-step explanation:

To find the percentage of 55,000, multiply 55,000 x 0.15, giving you 8,250. Add this to 55,000 to get 63,250 dollars :)

The graph of F(x) = 3 • (0.5)^x is represented by the third graph in the image. The correct option is C.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The graph of the function is cutting an intercept at point 3 at the y-axis and is lying about the x-axis. The graph of the function is attached with the answer below.

Therefore, the graph of F(x) = 3 • (0.5)^x is represented by the third graph in the image. The correct option is C.

Answer:

x ≈ 24.4

Step-by-step explanation:

Given

tan18° = [tex]\frac{x}{75}[/tex] ( multiply both sides by 75 )

75 × tan18° = x , then

x ≈ 24.4 ( to 1 dec. place )

Answer:

C. 189

Step-by-step explanation:

Each triangle is 27 which makes it 108, and 108+81=189

Surface area = sum of all area, which is the total of 4 triangles and 1 square.

1 square = 9 x9 = 81

each triangle = (6 x 9)/2 = 27

so 4 triangles = 27 x 4 = 108

=> total = 108+ 81 = 189

I Think It's A

Answer:

0.17

Step-by-step explanation:

First, we can easily calculate that the area of the rectangle is 7 * 5 = 35

Next, to find the probability of choosing a point in the triangle, we need to find the area of the triangle compared to the area of the rectangle. Notice that the square has nothing to do with the solution because we are only interested in finding the probability for the triangle!

Since the area of the triangle is base * height / 2 or  4 * 3/2 = 6, the probability is 6/35. Plugging this value in the calculator gives us 0.17

Answer:

  5.3

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh . . . . where b is the base length and h is the height.

The figure gives an area and shows b=h, so we have ...

  14 ft² = 1/2(h)(h)

  28 ft² = h² . . . . . . . . . multiply by 2

  h = √28 ft ≈ 5.3 ft . . . . . take the square root

Answer:

your answer is C i hope this helps sorry if i am wrong

Step-by-step explanation:

Answer:

There are ten possible digits (0 to 9).

If they can be repeated, you're looking at 10 * 10 *10 * 10 * 10, or 105

This means 100000 possible zip codes if repeatable.

If not, you're looking at one less each time:

10 * 9 * 8 * 7 * 6

90 * 56 * 6

540 * 56 = 30240 zip codes without any repetitions.

Answer:

a. 28 centimeters

Answer:

b. The fitted regression line is approximately Y = 82.42(runtime)

Step-by-step explanation:

The regression line is Y=  aX + b

here b= 82.42   a = -3.31

Hence the regression equation is

Y= 82.42- 3.31 X

where x is the runtime and the slope  is given by b.

Option  a is correct because from the above equation we see that for every additional minute it takes to run the 1500 m the estimated oxygen consumption rate decreases by 3.31.

Option b is incorrect because the runtime is not given by Y it is given by X.

Option C is correct  as  

Y= 82.42-3.31*10

Y= 82.42-33.1

Y= 49.32  almost 50

Option d is also correct that the equation line shows a relationship between oxygen consumption and the run time.

Option e is also correct because the slope is given by b and b= 82.42

Answer: A property occurring in the example 11.5 + (-11.5) = 0, is additive inverse.

Step-by-step explanation:

A property where sum of any number and its inverse is equal to zero is called additive inverse property.

For example, 11.5 + (-11.5) = 0

Here, 11.5 is the number and its inverse is (-11.5). The sum of both these is equal to zero. Hence, it shows a property of additive inverse.

Thus, we can conclude that property occurring in the example 11.5 + (-11.5) = 0, is additive inverse.
