A normal distribution has a mean 20 and standard deviation 5. What is the z score that corresponds to the value x=222

sashaice [31]

Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. $\mu=20$

$\sigma=5$

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 22, we have

$z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4$

Hence, the z score that corresponds to the value x=22 is 0.4

PLS HELP ASAP find the measure of side b. round to the nearest whole number

ludmilkaskok [199]

Answer:

b=204

Step-by-step explanation:

The law of sine states that: $\frac{SinA}{a} =\frac{SinB}{b} =\frac{SinC}{c}$

We know that a triangle has 180° total, so we can subtract the two angle measures we know to find the third angle: $180-90-41=49$ °.

Using these two things, we can come up with the equality $\frac{Sin90^{o} }{270} =\frac{Sin49^o}{b}$ , which we can use to solve for side b.

$\frac{Sin90^o}{270} =\frac{1}{270}$ , so we know that $\frac{1}{270} =\frac{Sin49^o}{b}$ .

Next, we would multiply both sides by b to get $\frac{1}{270}b=Sin49^o$ .

Sin49°≈0.75471, so to find b we would multiply 0.75471×270=203.77

Since the problem asks us to round to the nearest whole number, b=204

Hope this helps! :)
