18 percent more means that he's making 100 percent of his prior salary+ an additional 18 percent of his prior salary.

The mathematical representation of this: 1.18*59,950

That's how you get the new and improved annual salary ;)

Answer:

I think the answer might be 700.

Answer:

The average rate of change is 2.

Step-by-step explanation:

We are given the function:

[tex]g(x)=-x^2+x+5[/tex]

And we want to find the average rate of change over the interval:

[tex]-4\leq x\leq 3[/tex]

The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.

Our first endpoint is given by:

[tex]g(-4)=-(-4)^2+(-4)+5=-15[/tex]

And our second endpoint is given by:

[tex]g(3)=-(3)^2+(3)+5=-1[/tex]

This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:

[tex]\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2[/tex]

The average rate of change is 2.

Answer:

The 3rd and 6th

Step-by-step explanation:

Make a system of equations, try to solve, and then see which statements apply.

let x be the cost of a DVD and y be the cost of a video game

Then you would have:

2x + y = 12

4x + 2y = 24

from turning the words into equations.

Now, solve:

first, multiply the first equation by 2

2x + y = 12 --> 4x + 2y = 24

Then, subtract the two equations:

4x + 2y = 24

- (4x + 2y = 24)

0 = 0

Since you have a number = a number, there are infinite solutions.

Go through the options they give you and see which ones are correct

o The system of linear equations that represents this situation has one solution

Not true, there are infinite

o The system of linear equations that represents the situation has no solution.

Not true

o The system of linear equations that represents the situation has infinitely many solutions.

o The DVD rentals cost more than video game rentals

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Mean of 25.5 centimeters and a standard deviation of 1.4 centimeters.

This means that [tex]\mu = 25.5, \sigma = 1.4[/tex]

These shoes will fit men with feet that are 24.6 to 28.8 centimeters long. What percentage of boys aged 16 to 17 will not be able find shoes that fit in this​ store?

Less than 24.6:

The proportion is the pvalue of Z when X = 24.6. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{24.6 - 25.5}{1.4}[/tex]

[tex]Z = -0.64[/tex]

[tex]Z = -0.64[/tex] has a pvalue of 0.2611

More than 28.8:

The proportion is 1 subtracted by the pvalue of Z when X = 28.8. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{28.8 - 25.5}{1.4}[/tex]

[tex]Z = 2.36[/tex]

[tex]Z = 2.36[/tex] has a pvalue of 0.9909

1 - 0.9909 = 0.0091

0.2611 + 0.0091 = 0.2702

0.2702*100% = 27.02%

27.02% of boys aged 16 to 17 will not be able find shoes that fit in this​ store

Answer:

The correct answer here is A. x = 17.

How I found this out:

3x + 3 and 5x - 7 are going to be different solutions in the end.  

I did the process of elimination.

First, I subsituted, 17 for x. 3 X 17 + 3 = 54. 5 X 17 - 7 = 78.

I then took 180 - 54 - 48 = 78 and 180 - 78 - 48 = 54, just to make sure they are positive numbers and not negative.

Since they work out, I chose this as my correct answer to your question.

Answer: 5.22

Step-by-step explanation:

Given

[tex]\angle A=103^{\circ}[/tex]

Sine law is    [tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}\\[/tex]

Here, a=8, c=5

Putting values

[tex]\Rightarrow \dfrac{8}{\sin 103}=\dfrac{5}{\sin C}\\\\\Rightarrow \sin C=\dfrac{5}{8}\sin 103^{\circ}=0.6089\\\Rightarrow C=37.51^{\circ}[/tex]

[tex]\Rightarrow \angle B=180^{\circ} -103^{\circ}-37.51^{\circ}\\\Rightarrow \angle B=39.49^{\circ}[/tex]

If b=m, then

[tex]\Rightarrow \dfrac{8}{\sin 103^{\circ}}=\dfrac{m}{\sin 39.49^{\circ}}\\\\\Rightarrow m=\dfrac{\sin 39.49^{\circ}}{\sin 103^{\circ}}\times 8=5.22[/tex]

The number of vanilla cupcakes at the party will be 8.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that at a party, the ratio of chocolate cupcakes to vanilla cupcakes is 4 to 3. If there are 24 chocolate cupcakes.

The number of cupcakes will be calculated as:-

4 / 3 = 24 / V

V = ( 24 x 3 ) / 4

V = 18

Hence, the quantity of vanilla cups is 18.

Answer:

0.367 = 36.7% probability that the student gets fewer than 2 questions correct

Step-by-step explanation:

For each question, there are only two possible outcomes. Either he guesses the correct answer, or he does not. The probability of guessing the correct answer on a question is independent of any other question. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

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

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

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

And p is the probability of X happening.

8 questions on it

This means that [tex]n = 8[/tex]

4 choices.

One of them is correct, which means that [tex]\pi = \frac{1}{4} = 0.25[/tex]

What is the probability that the student gets fewer than 2 questions correct?

This is

[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]

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

[tex]P(X = 0) = C_{8,0}.(0.25)^{0}.(0.75)^{8} = 0.1[/tex]

[tex]P(X = 1) = C_{8,1}.(0.25)^{1}.(0.75)^{7} = 0.267[/tex]

[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.267 = 0.367[/tex]

0.367 = 36.7% probability that the student gets fewer than 2 questions correct

Answer:

Any number 5 and below

Step-by-step explanation:

We are given the expression that the difference between a number and 3 is no more than 2. Break down the expression and spot the key word of "difference," therefore meaning that the unknown number "x" and 3 is equal or less than 2. We can create the algebraic expression of x - 3, now since the answer must equal 2 or below 2, we can create the inequality :

x - 3 ≤ 2

Now the only numbers that are allowed to be inputted here is 5 and below.

The solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.

Let us denote the number as "x," we can express the given statement as an inequality:

|x - 3| ≤ 2

This inequality states that the absolute value of the difference between x and 3 is less than or equal to 2.

If x - 3 ≥ 0 (x ≥ 3)

In this case, the absolute value can be removed:

x - 3 ≤ 2

x ≤ 2 + 3

x ≤ 5

and if x - 3 < 0 (x < 3)

The absolute value becomes negative:

-(x - 3) ≤ 2

x + 3 ≤ 2

x ≤ 2 - 3

x ≤ -1

x ≥ 1

Combining the results from both cases, we have:

x ≤ 5 or x ≥ 1

Therefore, the solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.
