Answer:

Conversion a mixed number 16 3

8

to a improper fraction: 16 3/8 = 16 3

8

= 16 · 8 + 3

8

= 128 + 3

8

= 131

8

To find new numerator:

a) Multiply the whole number 16 by the denominator 8. Whole number 16 equally 16 * 8

8

= 128

8

b) Add the answer from previous step 128 to the numerator 3. New numerator is 128 + 3 = 131

c) Write previous answer (new numerator 131) over the denominator 8.

Sixteen and three eighths is one hundred thirty-one eighths

Conversion a mixed number 9 5

8

to a improper fraction: 9 5/8 = 9 5

8

= 9 · 8 + 5

8

= 72 + 5

8

= 77

8

To find new numerator:

a) Multiply the whole number 9 by the denominator 8. Whole number 9 equally 9 * 8

8

= 72

8

b) Add the answer from previous step 72 to the numerator 5. New numerator is 72 + 5 = 77

c) Write previous answer (new numerator 77) over the denominator 8.

Nine and five eighths is seventy-seven eighths

Subtract: 131

8

- 77

8

= 131 - 77

8

= 54

8

= 2 · 27

2 · 4

= 27

4

The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 8) = 8. Cancelling by a common factor of 2 gives 27

4

.

In words - one hundred thirty-one eighths minus seventy-seven eighths = twenty-seven quarters.

Can someone help me with this?
yulyashka [42]

Answer:

Step-by-step explanation:

We need to find the error first.

We can do this by subtracting, to find the difference

2.4-1.9 = 0.5

the difference, or error, is 0.5

Now we find a percentage that describes how much more 2.4 is than 1.9

We can create an equation to solve this

2.4 = 1.9 Times x

Now we need to find the value of x

x= 1.2632

now we double check

1.9 Times 1.2632 = 2.4

Now we round to a whole number

1.2632 = 1

To convert a number to a percentage, you need to bring the number over a decimal point.

so 1 becomes .1, or 10 percent

[4C-04] An insurance policy reimburses a loss with a deductible of 5. That is, if a loss is less than 5, policy will pay zero. I
user100 [1]

Answer:

-3

Step-by-step explanation:

Given that an  insurance policy reimburses a loss with a deductible of 5. That is, if a loss is less than 5, policy will pay zero. If it is more than 5, then the policy will pay (loss - 5).

We have distribution of y as

f(y) = \frac{2}{y^3} , y>1\\      =0 otherwise

expected value of the benefit paid under the insurance policy

=E(Y-5)\\=E(Y)-5, by linearity property of expectation.

E(y) = \int\limits^\infty_1 {y(\frac{2}{y^3} )} \, dy\\=\frac{-2}{y} \\=-0+2\\=2

Hence expected value of the benefit paid under the insurance policy

=2-5 =-3
