Find the average rate of change of his annual salary between 2017 and 2020
We were told that the salary, t years after 2015 is given by the function,
S(t) = 3100t + 56000
When considering 2017, the number of years, t from 2015 is 2017 - 2015 = 2
We would substitute t = 2 into the function and find S(2)
Thus,
S(2) = 3100 x 2 + 56000 = 6200 + 56000 = 62200
When considering 2020, the number of years, t from 2015 is 2020 - 2015 = 5
We would substitute t = 2 into the function and find S(2)
Thus,
S(5) = 3100 x 5 + 56000 = 15500 + 56000 = 71500
Thus, we can say that
when
x1 = 2, y1 = 62200
when x2 = 5, y2 = 71500
Recall,
slope or average rate of change = (y2 - y1)/(x2 - x1)
average rate of change = (71500 - 62200)/(5 - 2) = 9300/3
average rate of change = 3100

Amira is younger than Marques. Their ages are consecutive integers. Find Amira's age if the sum of Amira's age and 2 times Marques's age is 38.
Amira's age is 12 years when Amira is younger than Marques and their ages are consecutive integers and the sum of Amira's age and 2 times Marques's age is 38.
According to the question,
We have the following information:
Amira is younger than Marques.
Their ages are consecutive integers.
The sum of Amira's age and 2 times Marques's age is 38.
Now, let's take Amira's age to be x years.
Then, Marques's age will be (x+1) years.
So, we have:
x + 2(x+1) = 38
x + 2x + 2 = 38
3x+2 = 38
3x = 38-2 (Moving 2 from the left hand side to the right hand side will result in the change of the sign from plus to minus.)
3x = 36
x = 36/3
x = 12 years
Hence, Amira's age is 12 years.

What is the measure of C?
Please show your work if you want to be brainiest!
The measure of ∠C in the given triangle is 58°.
According to the question,
We have the following information:
ACD is a triangle where we have BD as an altitude on the side AC.
Now, we know that the altitude on any side makes an angle of 90° or in other words, it can be said that it makes a right angle.
Now, we have two right-angled triangle: ABD and CBD.
We have ∠ADB = 32°.
Now, ∠CDB will also be equal to 32° because the altitude bisects the angle (in two equal parts).
We know that the sum of the three angles in a triangle is 180°.
In ΔCBD, we have:
∠B + ∠C + ∠CDB = 180°
90° + ∠C + 32° = 180°
∠C + 122° = 180°
∠C = (180-122)°
(Moving 122 from the left hand side to right hand side will result in the change of sign.)
∠C = 58°
Hence, the measurement of ∠C in the given triangle is 58°.

Find the value of x .
Answer:
x = 113
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 8 , then
sum = 180° × 6 = 1080°
sum the interior angles and equate to 1080
x + 137 + 144 + 139 + 123 + 150 + 142 + 132 = 1080
x + 967 = 1080 ( subtract 967 from both sides )

2. a. (-1,4)
3. c. (-2,2)
Answer: 1. b
2. a
3. c
Step-by-step explanation:
We will change the second equation to y form, then we get:
2x - y = - 6
- y = -2x - 6
y = 2x + 6
Then we plug in each point to see whether it fixes the equations.
a) 1. y = 3x + 8
4 ?= 3(-1) + 8
4 ?= -3 + 8
4 x 5
a) 2. y = 2x + 6
4 ?= 2(-1) + 6
4 ?= -2 + 6
4 = 4
Point a is a solution of the second equation, but not a solution for the first equation.
b) 1. y = 3x + 8
14 ?= 3(2) + 8
14 ?= 6 + 8
14 = 14
b) 2. y = 2x + 6
14 ?= 2(2) + 6
14 ?= 4 + 6
14 x 10
Point b only fits the first equation, but does not fix (not a solution) of the second equation.
c) 1. y = 3x + 8
2 ?= 3(-2) + 8
2 ?= -6 + 8
2 = 2
c) 2. y = 2x + 6
2 ?= 2(-2) + 6
2 ?= - 4 + 6
2 = 2
Point c fits both the first equations and the second equations.

0.895 with 95 repeating on and on as a simplified fraction can be re-written as 887/990.
How to determine the fractional equivalent of this repeating decimal?By critically observing the given number, we can reasonably and logically deduce that it has three (3) repeating digits. Since this number has three (3) repeating digits, we would have to multiply n by 1000 as follows:
1000n = 0.895
1000n = 895.95 .......equation 1.
10n = 8.95 .......equation 2.
Subtracting equation 2 from equation 1, we have:
1000n - 10n = 895.95 - 8.95
990n = 887
Dividing both sides by 990, we have:
n = 887/990

suppose a large shipment of televisions contained 9% defectives. if a sample of size 393 is selected, what is the probability that the sample proportion will differ from the population proportion by less than 3%? round your answer to four decimal places.
The probability that the sample percentage will deviate from the population proportion by less than 3% is 0.9624, or 96.24%.
We must comprehend the central limit theorem and the normal probability distribution in order to answer this query.
Distribution of Normal Probabilities
The z-score formula can be used to address problems with normal distributions.
The z-score of a measure X in a set with mean and standard deviation can be calculated as follows:
The Z-score calculates how far a measure deviates from the mean by standard deviation. We look at the p-value linked with this Z-score after determining the Z-score by consulting the z-score table. This p-value represents the probability that the measure's value is less than X, or the percentile of X. 1 is subtracted from the p-value, giving us the likelihood that the value of the metric exceeds X.
Imagine that 9% of a huge shipment of televisions were defective.
As a result, the sample size has a p value of 0.09
As a result, n=393
Standard deviation and the mean
u=p= 0.09
s= sqrt(p(1-p)/n)
s=sqrt(0.09*0.91/393)= 0.0144
What is the likelihood that the sample percentage and population proportion will deviate by less than 3%?
The ratio of 0.09 - 0.03 = 0.06 to 0.09 + 0.03 = 0.12 is the result of subtracting the p-value of Z when X = 0.12 from the p-value of Z when X = 0.06.
X = 0.12
By the Central Limit Theorem
Z= x-u/s
Z=2.08 has a p-value of 0.9812
X = 0.06
Z= x-u/s
Z=-2.08 has a p-value of 0.0188
0.9812 - 0.0188 = 0.9624

Answer:
x = 58°
∠P = 58°
∠PQR = 64°
Step-by-step explanation:
If you add the two nonadjacent angles together they will equal the exterior angle. Setup up an equation using that info.
[tex]58 +x=2x[/tex]
Solve for x.
[tex]58 +x-x=2x-x\\58=x[/tex]
Since ∠P is the same as x, ∠P = 58°
To find ∠PQR, add ∠P and ∠R together and then subtract from 180°. You subtract from 180° because the sum of the three angles of a triangle equal 180°.
58 + 58 = 116
180 - 116 = 64°
∠PQR = 64°

The points that we are going to choose are the intercepts. The x-intercept is the value of x when y = 0, hence:
5x = 20
x = 20/5
x = 4.
Meaning that point (4,0) is on the graph of the function.
The y-intercept is the value of y when x = 0, hence:
3y = 20
y = 20/3
y = 6.67.
Meaning that point (0, 6.67) is on the graph of the function.
The graph is plotted with a line passing through the points (4,0) and (0, 6.67).

Probability is the study of possible outcomes of events, together with the probabilities and distributions of those occurrences.
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
To calculate probability, divide the total number of outcomes by the total number of possible possibilities. There are differences between probability and odds.
Odds are computed by dividing the likelihood that an event will occur by the likelihood that it won't.
From the stated circumstance,
Total ways = [tex]4^{5}[/tex]= 1024
