Answer:

percentage = 528/ 3,300*100= 16%

Step-by-step explanation:From the pie chart we can see that saving are 528 dollars, so

now we need to calculate total from the given pie chart, which is

3,300 dollars. So percentage is savings( 528 dollars) divided by total( 3,300 dollars) and then finally multiply by 100

The length of the unknown side of the triangle using similar triangle ratio concept is; x = 24

We want to find the length of the unknown side of the similar triangles.

Similar triangles are defined as triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. Thus, we can say that if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

From the given triangle ADE which is divide into a similar triangle ABC with an unknown side x, we can use the concept of similar triangle ratios to get the unknown value of x as;

6/x = 8/(x + 8)

Cross multiply to get;

6(x + 8) = 8x

6x + 48 = 8x

8x - 6x = 48

2x = 48

x = 48/2

x = 24

The most appropriate choice for probability will be given by-

Probability of not getting two cans of coke is  [tex]\frac{49}{52}[/tex]

What is probability?

Probability of an event is the chance of occurance of that event.

Probability is calculated by Number of favourable outcomes divided by total number of outcomes

Here,

Number of lemonades in a cooler = 16

Number of sprite in a cooler = 5

Number of cans coke in a cooler = 10

Number of cans of root beers in a cooler = 9

Total number of refreshments = 16 + 5 + 10 + 9

                                                  = 40

Probability of getting a can of coke in the first draw = [tex]\frac{10}{40}[/tex]

                                                                                       = [tex]\frac{1}{4}[/tex]

Probability of getting a can of coke in the second draw = [tex]\frac{9}{39}[/tex]

                                                                                              = [tex]\frac{3}{13}[/tex]

Probability of getting two cans of coke in the two draws = [tex]\frac{1}{4} \times \frac{3}{13}[/tex]

                                                                                              = [tex]\frac{3}{52}[/tex]

Probabilty of not getting two cans of coke in the two draws = [tex]1-\frac{3}{52}[/tex]

                                                                                                   = [tex]\frac{52-3}{52}[/tex]

                                                                                                   = [tex]\frac{49}{52}[/tex]

Answer:

Approximately $18 each month.

Step-by-step explanation:

This is quite simple. So, we know that there are 12 months in a year. And we know that in a year, the store has given out discounts totaling up to $216. All we have to do is divide the total number by how many months there are in a year.

[tex]216\div12=18[/tex]

This means that the store gives out $18 of discounts per month.

Using the binomial distribution, the probabilities are given as follows:

1) Three girls in a family of five children: 0.3125 = 31.25%.

2) At least two boys in a family of seven children: 0.9375 = 93.75%.

3) Total of 15 when four dice are thrown:  0.1080 = 10.80%.

4) At least two left-handed people in a group of 7: 0.1497 = 14.97%.

5) At least five of them have the same birth date: 0%.

The formula for the probability of x successes is:

[tex]P(X = x) = C(n,x).p^{x}.(1-p)^{n-x}[/tex]

[tex]C(n,x) = \frac{n!}{x!(n-x)!}[/tex]

The parameters are given by:

A children is equally as likely to be a boy or a girl, hence the parameters are given as follows:

n = 5, p = 0.5.

The probability is P(X = 3), hence:

P(X = 3) = C(5, 3) x (0.5)³ x (0.5)² = 0.3125 = 31.25%.

The parameters are:

n = 7, p = 0.5.

The probability of at least two boys is:

P(X >= 2) = 1 - P(X < 2).

In which:

P(X < 2) = P(X = 0) + P(X = 1).

Then:

This one is simple probability, number of desired outcomes divided by the number of total outcomes.

When 4 dice are thrown, we have that:

Hence the probability is:

p = 140/(6^4) = 0.1080 = 10.80%.

The parameters are:

n = 7, p = 0.1.

Hence, similarly to item 2:

The parameters are:

n = 75, p = 1/365 = 0.0027.

Then the probability is:

P(X >=5) = 1 - P(X < 5).

In which:

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4).

Using a calculator, it is found that P(X < 5) = 1, hence the probability is of 0%, as P(X >=5) = 1 - 1 = 0.

The average number of customers contacted each day is 13. We used the basic average method which is explained below.

The formula for calculating the average is:

Sum of all the observations ÷ Total number of observations

So, according to the formula

Sum of all the observations = People contacted on (Monday+ tuesday+wednesday+thursday+friday)

= 15+12+14+11+13

= 65

Number of observations = 5

So putting values in the formula, we get

If the bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months, then the interest rate is 30%

The initial amount = $1100

The  final amount = $1265

So simple interest = 1265-1100

= $165

Time period = 6 months = 6/12 years

We know

Simple interest I = P×r×t

Where P is the initial amount

r is the interest rate

t is the time period

Substitute the values in the equation

165 = 1100×r×(6/12)

165 = 550×r

r = 165/550

r = 0.3

r = 30%

Hence, If the bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months, then the interest rate is 30%

From the graph of the function, it's behavior on the intervals is given as follows:

Looking at the graph, we get that a function f(x) is increasing when it is "moving northeast" along the xy-plane, that is, to the right and up on the graph, meaning that when x increases, y increases.

Hence, from the graph of the function, it is increasing for the values to the right of x = 0, that is, on the interval x > 0.

Looking at the graph, we get that a function f(x) is decreasing when it is "moving southeast" along the xy-plane, that is, to the right and down on the graph, meaning that when x increases, y decreases.

Hence, from the graph of the function, it is decreasing for the values to the left of x = 0, that is, on the interval x < 0.

Explanation:

First we simplify the given equation

Final answer:

Using equation;

The monthly payment is 67.5 dollars

The hours of labour that is required to replace the water pump is 4 hours

The purchase of the large TV including finance charges is 1615 dollars . A down payment of 400 dollars was paid. The remainder was paid in 18 monthly instalment payment.

Therefore, using equation,

let

x = amount paid each month

The monthly payment can be found as follows:

1615 = 400 + 18x

1615 - 400 = 18x

1215  = 18x

divide both sides by 18

x = 1215 / 18

x = 67.5 dollars

Therefore,

monthly payment = 67.5 dollars

The cost of replacing a water pump was 465 dollars. This include 145 dollars for water pump plus 80 dollars per hour for labour .

The number of hours for labour that was used to replace the water pump can be calculated as follows:

Using equation,

465 = 145 + 80h

where

h = number of hours for labour

465 - 145 = 80h

320 = 80h

Percentages are basically fractions with a denominator of 100. We use the percent symbol (%) beside a number to indicate that it is a percentage. A percentage is a relative value that represents the hundredth part of any quantity. One percent (symbolized 1%) is one hundredth part; thus, 100 percent represents the entire amount.

To manually calculate percentages, follow these steps:

1. Determine the number's initial format to be converted to a percentage.

The decimal or fraction format of the number to be converted to a percentage can be used. The next mathematical process to be performed on the number will be determined by the initial format.

2. Perform a mathematical calculation on the number to be converted to a percentage.

If the number to be converted to a percentage is a decimal number, such as 0.57, you may not need to proceed to the next step.

x + .12x = 3.36  Combine like terms

1.12x = 3.36  Divide both sides of the equation by 1.12

x = 3

=======================================

Work Shown:

12% = 12/100 = 0.12

x + 12% of x = x + 0.12x = 1.12x = 3.36

1.12x = 3.36

x = 3.36/1.12

x = 3
