Answer:

12 and 16

Step-by-step explanation:

The ratio between the groups is 3:4, so the fractions are 3/7 and 4/7.

3/7 (28) = 12

4/7 (28) = 16

Check your answer: 12 + 16 = 28, and 12/16 = 3/4.

n200080 [17]

Given:

Consider the expression is \sqrt{-12}.

To find:

The value of given expression.

Solution:

We have,

\sqrt{-12}

It can be written as

\sqrt{-12}=\sqrt{-1\times 12}

\sqrt{-12}=\sqrt{-1}\times \sqrt{12}      [\because \sqrt{ab}=\sqrt{a}\sqrt{b}]

\sqrt{-12}=i\times \sqrt{12}      [\because \sqrt{-1}=i]

\sqrt{-12}=\sqrt{12}i

Therefore, the value of given expression is \sqrt{12}i.

Note: all options are incorrect.

julia-pushkina [17]

Answer:

89.04% of the data points will fall in the given range of z = − 1.6 and z = 1.6      

Step-by-step explanation:

We are given a normally distributed data.

We have to find the percentage of data that lies within the range  z = − 1.6 and z= 1.6

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(-1.6 \leq z \leq 1.6)\\= P(z \leq 1.6) - P(z \leq -1.6)\\\text{Calculating the value from standard normal table}\\= 0.9452 - 0.0548 = 0.8904= 89.04\%

89.04% of the data points will fall in the given range of z = − 1.6 and z= 1.6
