The person is traveling 30 mph.

The car is traveling 45 mph.

Just mulitply 15 x 3 and 10 x 3.

Let’s break the numbers down.

10 + 5 = 15. So we can break 15 down like how you add 15.

10 x 3 = 30.

5 x 3 = 15.

Let’s add 30 and 15 together.

30 + 15 = 45.

Let’s now multiply 10 and 3.

10 x 3 = 30.

I hope this helped!

Absorption rates into the body are important considerations when manufacturing a generic version of a brand-name drug. A pharmac
Darya [45]

Answer:

Correct option: (D).

Step-by-step explanation:

A null hypothesis is a hypothesis of no difference. It is symbolized by <em>H₀</em>.

A Type I error is the probability of rejection of the null hypothesis of a test when indeed the the null hypothesis is true.

The type I error is also known as the significance level of the test.

It is symbolized by P (type I error) = <em>α</em>.

In this case the researcher wants to determine whether the absorption rate into the body of a new generic drug (G) is the same as its brand-name counterpart (B) or not.

The hypothesis for this test can be defined as:

<em>H₀</em>: The absorption rate into the body of a new generic drug and its brand-name counterpart is same.

<em>Hₐ</em>: The absorption rate into the body of a new generic drug and its brand-name counterpart is not same.

The type I error will be committed when the null hypothesis is rejected when in fact it is true.

That is, a type I error will be made when the the results conclude that the absorption rate into the body for both the drugs is not same, when in fact the absorption rate is same for both.

Thus, the correct option is (<em>D</em>).

Help how do i solve for this ?
Tanya [424]

Answer:

Solution:

Given,

Radius(r) = 11 ft

C = ?

Now,

c = 2\pi \: r

C = 2 × 3.14 × 11

= 70 cm

again,

C = 360°

angle = 315°

So,

C = 70 cm

or, 360° = 70 cm

or 1° = 70/360°

or 1° = 7/36

again ,

area = 7/36 × 315°

= 61.25 cm
