Answer:

9:4

Step-by-step explanation:

English

Ana uses 3/4 cup of china juice for every 1/3 cup of lemon juice to make a soda. What is the ratio of cups of china juice to cups of lemon juice?

<u>Solution</u>

To find the ratio of cups of china juice to cups of lemon juice, we divide

\frac{3}{4}

by

\frac{1}{3}and simplify.

We set up the division as follows:

\frac{3}{4}  \div  \frac{1}{3}

Multiply the first fraction by the reciprocal of the second fraction.

\frac{3}{4}  \times  \frac{3}{1}

This gives us;

\frac{3 \times 3}{4 \times 1}

We then obtain:

\frac{9}{4}

Therefore the ratio of cups of china juice to cups of lemon juice is 9:4

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corpor
sesenic [268]

Answer:

Null Hypothesis, H_0 : \mu = 136 mm Hg  

Alternate Hypothesis, H_A : \mu\neq 136 mm Hg

In this context type I error is rejecting that the μ is equal to 136 mm Hg when in fact μ is equal to 136 mm Hg.

Step-by-step explanation:

We are given that the mean systolic blood pressure, μ, of CEOs of major corporations is different from 136 mm Hg, which is the value reported in a possibly outdated journal article.

He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 126 mm Hg and the standard deviation of the sample to be 18 mm Hg.

So, Null Hypothesis, H_0 : \mu = 136 mm Hg     {means that the mean systolic blood pressure, μ, of CEOs of major corporations is 136 mm Hg}

Alternate Hypothesis, H_A : \mu\neq 136 mm Hg      {means that the mean systolic blood pressure, μ, of CEOs of major corporations is 136 mm Hg}

Type I error states that the null hypothesis is rejected when in fact the null hypothesis was true. So, in this context type I error is rejecting that the μ is equal to 136 mm Hg when in fact μ is equal to 136 mm Hg.

Suppose the researcher decides not to reject the null hypothesis. It means the researcher is making a type I error.

​​​​​​​If K = F( A + B ) , find “ A ” if F = 2 , B = 3 , K = 10
Oxana [17]

Answer:

The value of A is 2

Step-by-step explanation:

F = 2 , B = 3 , K = 10

K = F( A + B )

10 = 2(A + 3)

10 = 2A + 6

Now, Subtract 6 from each side we get,

10 - 6 = 2A + 6 - 6

4 = 2A

2A = 4

Now, divide both side by 2 we get,

2A/2 = 4/2

A = 2

Thus, The value of A is 2

<h3><u>FOR V</u><u>ERIFICATION</u><u> ONLY</u> :-</h3>

K = F( A + B )

10 = 2(2 + 3)

10 = 2(5)

10 = 10

L.H.S = R.H.S

Hence Proved!
