Teresa has scored 77, 80, 63, 61 and 92 on previous test what score does she need on her next test on her average will be 77

Rainbow [258]

Average = 77=(77+80+63+61+92+Next test)/6

Therefore, 77*6=77+80+63+61+92+Next test

Next test score = (77*6)- (77+80+63+61+92)= 89

Answer:

$P(32) = \frac{1}{90}$

$P(Odd) = \frac{1}{2}$

$P(Multiples\ 5) = \frac{1}{5}$

Step-by-step explanation:

Given

Sample Space = 10 to 99

First, we calculate the sample size (n)

$n = 99 - 10 + 1$

$n = 90$

Solving (a): P(32)

In 10 to 99, there is only 1 32.

So,

$P(32) = \frac{n(32)}{n}$

$P(32) = \frac{1}{90}$

Solving (b): P(Odd)

There are 45 odd numbers between 10 and 99

i.e.

$n(Odd) = 45$

So:

$P(Odd) = \frac{n(Odd)}{n}$

$P(Odd) = \frac{45}{90}$

$P(Odd) = \frac{1}{2}$

Solving (c): P(Multiple of 5)

There are 18 multiples of 5 between 10 and 99

i.e

$P(Multiples\ 5) = \frac{18}{90}$

$P(Multiples\ 5) = \frac{1}{5}$

What is the value of y so that the ordered pair (5, y) is a solution to the equation –5x + y = –40?

DedPeter [7]

$-5x + y = -40\\\\x=5\\\\-5(5)+y=-40\\-25+y=-40\\y-25 = -40\\y -25+ 25 = -40+25\\y = -40+25\\\\\boxed{\bf{y=-15}}$

Answer is C.
