Hey!

------------------------------------------------

~Cross Multiply

z/42 * 25/70 → 70z = 1050

~Divide 70 to both sides

70z/70 = 1050/70

~Simplify

z = 15

------------------------------------------------

Hence, the answer is \Large\boxed{\mathsf{z~=~15}}

------------------------------------------------

Write eighteen hundredths as a decimal.<br> P.S. dont put nothing stupid , just answer .
pishuonlain [190]

Eighteen hundredths as a decimal is 0.18

<h3><u>Solution:</u></h3>

We have to find eighteen hundredths as a decimal

Eighteen hundredths means 18 over one hundred

We have to write 18 over one hundred as decimal

A decimal is a fraction written in a special form

Let us first write 18 over one hundred in fraction form

Eighteen hundredths = 18 over one hundred

\rightarrow \frac{18}{100}

Now divide 18 by 100 to get the decimal form

\rightarrow \frac{18}{100} = 0.18

Thus the eighteen hundredths as a decimal is 0.18

Suppose the variable x is represented by a standard normal distribution. What is the probability of x &gt; 0.3 ? Please specify
uysha [10]

Answer: 0.38

Step-by-step explanation:

Since the variable x is represented by a standard normal distribution, the probability of x > 0.3 will be calculated thus:

P(x > 0.3)

Then, we will use a standard normal table

P(z > 0.3)

= 1 - p(z < 0.3)

= 1 - 0.62

= 0.38

Therefore, p(x > 0.3) = 0.38

The probability of x > 0.3 is 0.38.

Please help solve for PQ.
DerKrebs [107]
This problem cannot be solved unless we are given figure NPQR is a rhombus.
In that case, then all sides are equal, meaning 
5x+16=9x-32
Solve for x
9x-5x=16+32
4x=48
x=12

Each side (including PQ) then equals 5x+16=5*12+16=76
