Answer:

79+94+91+92+test5)/5=90

The lowest score have to be 94

Step-by-step explanation:

Our goal is gona be to have an average of 90, it can be higher but we are going to use this.

For average the equation is

(test1+test2+test3+test4+test5)/5=average

We know the result for the first 4 tests

Test 1=79

Test 2=94

Test 3=91

Test 4=92

But we dont know test 5

(79+94+91+92+test5)/5=average

Our goal for the average is 90

(79+94+91+92+test5)/5=90

79+94+91+92+test5=90*5

test5=450-79-94-91-92

Test5=94

The product of 5 and a number less 6 is 4. write the phrase as an algebraic equation.

kvasek [131]

5 + x - 6 = 4
x= 5

5 plus 5 equals 10 and 10 minus 6 is equal to 4.

Question 4

Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

Given

See attachment for chart

Required

Number of off days

To do this, we simply calculate the expected value of the chart.

This is calculated as:

$E(x) = \sum x * f$

Where

x = days

f = chances

So, we have:

$E(x) = 0* 0.3 + 1 *0.2 + 2 * 0.25 + 3 * 0.2 + 4 * 0.02 + 5 * 0.01 + 6 * 0.01 + 7 * 0.01$

$E(x) = 1.56$

$E(x) \approx 2$
