Answer:

The z- score for a value of 3.99 will be 3.38.

Step-by-step explanation:

It is given that the mean of a set of data is -3.82 and its standard deviation is 2.31.

Thus, the value of the z-score= $\frac{value-mean}{standarddeviation}$

= $\frac{3.99-(-3.82)}{2.31}$

= $\frac{3.99+3.82}{2.31}$

= $\frac{7.81}{2.31}$

= $3.38$

Thus, the z- score for a value of 3.99 will be 3.38.

Answer:

75.062c $m^{2}$

Step-by-step explanation:

To find the missing side use pythagorean theorem

So $6^{2} +b^2=8.5^2$

Solve for b, b= 6.021

To find the area use $\frac{1}{2}$ bh

So $\frac{1}{2}$ (6.021+19)(6)= area

And you get 75.062

Answer:

Answer is D

Step-by-step explanation:

First use sine to figure out x

so "sin(31) = 12 ÷ x"

mulitply both sides by x and you get "x * sin(31) = 12"

divide both side by sin(31) so you get "x = 12 ÷ sin(31)"

after plugging it in a calculator, you get 23.2992 and just rounf to the nearest tenth and you get 23.3
