Step-by-step explanation:

change the ÷ into × flip the number too.

$\frac{85}{10} \div \frac{11}{6} = \frac{85}{10} \times \frac{6}{11}$

Reduce the fraction with 5

$\frac{85}{10} \times \frac{6}{11} = \frac{17}{2} \times \frac{6}{11}$

Reduce the numbers with the greatest common factor 2

$\frac{17}{2} \times \frac{6}{11} = \frac{17}{1} \times \frac{3}{11}$

Just multiply now, To multiply the fractions , multiply the numerators and denominators separately

$\frac{17 \times 3}{1 \times 11} = \frac{51}{11}$

Solution :

$\frac{51}{11}$

Alternative form:

$4 \frac{7}{11}$

$4.63$

Kent multiplies both sides of the equation below by an expression. k startfraction 12 over k endfraction = 8 then he moves all t

Pepsi [2]

The resulting value of k is 12/7.

<h3>What is a fraction?</h3>

Fractions are the numerical values that are a part of the whole. A whole can be an object or a group of objects.

The steps below are presented in order to arrive at the value of k of the given equation.

First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator.

The solution of the equation will be;

$\rm \dfrac{k+12}{k}(k) = 8(k)\\\\\dfrac{k+12}{k}=8\\\\k+12=8k\\\\8k-k=12\\\\ 7k=12\\\\k =\dfrac{12}{7}$

Hence, the resulting value of k is 12/7.

The life span of a domestic cat is normally distributed with a mean of 15.7 years and a standard deviation of 1.6 years. a. Find

Anvisha [2.4K]

Answer

a. 0.856

b. 0.78071

c. It is not unusual

d. 13.65 years old

Step-by-step explanation:

The life span of a domestic cat is normally distributed with a mean of 15.7 years and a standard deviation of 1.6 years.

We solve this question using z score formula:

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

a. Find the probability that a cat will live to be older than 14 years.

For x > 14 years

z = 14 - 15.7/1.6

z = -1.0625

Probability value from Z-Table:

P(x<14) = 0.144

P(x>14) = 1 - P(x<14) = 0.856

b. Find the probability that a cat will live between 14 and 18 years.

For x = 14 years

z = 14 - 15.7/1.6

z = -1.0625

Probability value from Z-Table:

P(x = 14) = 0.144

For x = 18 years

z = 18 - 15.7/1.6

z= 1.4375

Probability value from Z-Table:

P(x = 18) = 0.92471

The probability that a cat will live between 14 and 18 years is calculated as:

P(x = 18) - P(x = 14)

0.92471 - 0.144

= 0.78071

c. If a cat lives to be over 18 years, would that be unusual? Why or why not?

For x > 18 years

z = 18 - 15.7/1.6

z= 1.4375

Probability value from Z-Table:

P(x<18) = 0.92471

P(x>18) = 1 - P(x<18) = 0.075288

Converting this to percentage:

0.075288 × 100 = 7.5288%

Hence, 7.5288% of the cats live to be over 18 years. Hence, it is not unusual.

d. How old would a cat have to be to be older than 90% of other cats?

From the question above, 10% of the cats would be older than 90% of other cats.

Hence, we find the z score of the 10th percentile

= -1.282

Hence,

-1.282 = x - 15.7/1.6

Cross Multiply

-1.282 × 1.6 = x - 15.7

- 2.0512 = x - 15.7

x = 15.7 -2.0512

x = 13.6488 years old

Approximately = 13.65 years old

Miguel has a credit card bill of $7250 with an interest rate of 16%. To pay his bill off in one year, he must make monthly payme

Tems11 [23]

Answer:

The extra amount to be paid = $ 309.15

Step-by-step explanation:

Credit card bill = $ 7250 .

Interest rate = 16 % .

<h3>AMOUNT TO BE PAID IN 1 YEAR</h3>

Monthly payment = $ 657.80

Total amount to be paid in a year = $ 657.80 × 12 = $ 7893.6

Interest amount in 1 year = $ 7893.6 - $ 7250 = $ 643.6.

<h3>AMOUNT TO BE PAID IN 18 MONTHS </h3>

Monthly payment = $ 455.71.

Total amount to be paid in a 18 months = $ 455.71 × 18 = $ 8202.78

Interest amount to be paid in 18 months = $ 952.78 .

The extra amount to be paid = $ 8202.78 - $ 7893.6 = $ 309.15
