A=bh, for b (an area formula)

1 answer:

5 0

If you are trying to make B the subject, you have to divide both sides by 'h' because we need to get rid if 'h' to get 'b' on it's own, and you do the opposite of times - which is to divide. Once you divide both sides by h, you should end up with this:

A/h=b

Use elimination to solve!!!!!!

REY [17]

For easier notation lets use: Nn=x and Nd=y

x+y=22
5x+10y=135

Multiply the first equation by 5 to get
5x+5y=110

Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17

Suppose a normal distribution has a mean of 50 and a standard deviation of 3. What is P(x≤53)?

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.

$z=\frac{53-50}{3}=1$

The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.
