Answer:

B.) This is not a binomial experiment, because the number of trials is not fixed.

Step-by-step explanation:

For a certain experiment to be classed as a binomial, it has to meet some criteria ;

Which include ;

1.) The trials should be independent.

11.) Each trial should be classifiable into one of success of failure.

111). There is a fixed mean probability for success and failure

IV) There is a fixed number of trials, in experiment described above, the number of trials isn't fixed, it is variable, as the trial will continue until a defective item is obtained.

Michelle wishes to build a square pool in her backyard. She has saved enough to build a pool with the area of 150 square feet. W

When it comes to finding the area of spaces, you must determine its shape. In this case, the shape of the pool is a square. From there, we will use the formula to find the area of a square.

Area = (side)^2

Since the square of the square's side is its total area, then if vice versa, we have to find the square root of the area to find the length. Thus,

Length = √150 = 5√6 = 12.25 ft

$12,800 15% is taken out what's the answer

Anuta_ua [19.1K]

Answer:

$10,880

Step-by-step explanation:

15% = 15 ÷ 100 = 0.15

So 15% of 12800 = 0.15 x 12800 = 1920

Therefore, 12800 - 1920 = 10880

12800 x (1 - 0.15) = 10880

Mariulka [41]

9514 1404 393

Answer:

80.5°

Step-by-step explanation:

The applicable trig function is the tangent.

Tan = Opposite/Adjacent

In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...

tan(α) = 324/54

The value of the angle with this tangent is found using the arctangent function:

α = arctan(324/54) ≈ 80.5°

She should set her binoculars to 80.5°.

Which statement correctly compares the spreads of the distributions?

swat32

Answer:

b. the ranges of penguin heights are the same.

Step-by-step explanation:

Hello!

Statements:

Which statement correctly compares the spreads of the distributions?

a. the mode of penguin heights at county side zoo is greater than the mode at city view zoo.

b. the ranges of penguin heights are the same.

c. the range of penguin heights is greater at city view zoo than at county side zoo.

d. the range of penguin heights is greater at county side zoo than at city view zoo.

The mode and mean are measurements of central tendency, these indicate the position of a data set but don't show any information concerning the distribution of said data.

The range on the other had is a measurement of variance, it shows the difference between the maximum and minimum values of the data set and indicates its total dispersion.

City view Zoo R= 44-37= 7 cm

County side Zoo: R= 45-38= 7 cm

Both ranges are the same.

I hope this helps!
