Can someone solve 2x-3y=9 and give me the slope and y intercept SHOW WORK please

Dominik [7]

Answer:

The slope is 2/3 and the y-intercept is -3

Step-by-step explanation:

First you subtract 2/3 from both sides and get -3y=-2x+9. Then you divide -3 by -2 and -3 by 9 to get y=2/3-3.

Hope this helped I am not good at explaining but I did this unit like two months ago.

IQ is normally distributed with a mean of 100 and a standard deviation of 15. a) Suppose one individual is randomly chosen. Fin

nasty-shy [4]

Answer:

Step-by-step explanation:

Let X be the IQ

IQ is normally distributed with a mean of 100 and a standard deviation of 15.

a) the probability that this person has an IQ greater than 95

= $P(X\geq 95)\\=P(Z\geq \frac{95-100}{15} \\=P(Z\geq -0.33)\\=0.1293+0.5\\=0.6293$

=62.93%

b) the probability that this person has an IQ less than 125

$=P(X\leq 125) =P(X\leq 1.67)\\=0.5-0.4525\\=0.0475$

=4.75%

c) Sample size =500

$P(X$

No of people = 0.2486(500) =124.3

d) $P(x>140)\\= P(Z>2.6)\\=0.5-0.4953\\=0.0047$

No of persons = 0.0047(500) = 2.35
