Hunter-Best [27]3 years ago
8 0

Answer:

5y=24x

Step-by-step explanation:

<em>The question in English is</em>

If 4x= 5/6y then 5y=

we have

4x=\frac{5}{6}y

Solve for 5y

Multiply both sides by 6

6*4x=(6)*\frac{5}{6}y

Simplify

24x=5y

Rewrite

5y=24x

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>).

I need these three solved. I have a lot of math to do. the directions say solve each system of equations using substitution. sho
alekssr [168]

Answer:

5.

x + 2(x + 1) = 8 --> x = 2

y = 2 + 1 = 3

7.

3(9 + 2y) + 5y = 20 --> y = -7/11

x = 9 + 2(-7/11) = 85/11

9.

3(-1 - 2y) + 5y = -1 --> y = -2

x = -1 - 2(-2) = 3

The sum of the ages of Mr Lin and his son Ethan is 38 years. In three years' time, Mr Lin will be three times as old as his son.
Sati [7]

Answer:

Mr.Lin's present age is 30 years now. His son is 8 years old now.

Step-by-step explanation:

Let L = Mr.Lin's present age,

   S = his son's present age.

First equation  is

L + S = 38.       (1)

The second equation is  

L + 3 = 3*(S+3)   (2)   ("In three years' time, Mr.Lin will be three times as old as his son.")

From (1), express S = 38-L and substitute it into (2). You  will get

L + 3 = 3*((38-L)+3),   or

L + 3 = 114 - 3L + 9,

4L = 114 + 9 - 3,  

4L = 120,

L = 30.

A teacher claims that the proportion of students expected to pass an exam is greater than 80%. To test this claim, the teacher a
erica [24]

Answer:

z=-1.591

Step-by-step explanation:

Null Hypotheses,

H_0 : p=0.8\\H_a: p>0.80

So we use z-test for one population proportion (right-tailed test)

According to this informaton, we defined that

\alpha=0.05

z_c=1.64 (critical value)

So our Rejection region is R={z:z>1.64}

z=\frac{\bar{p}-p_0}{\sqrt{p_0(1-p_0)/n}} = \frac{0.755-0.8}{\sqrt{0.8(1-0.8)/200}}=-1.591

Not rejection.
