A(The initial value is 22, and the rate of change is 1.
B(The initial value is 22, and the rate of change is 15.
C(The initial value is 32, and the rate of change is 1.
D(The initial value is 32, and the rate of change is 15.
Answers
Answer:
B) The initial value is 22, and the rate of change is 15.
Step-by-step explanation:
The first point is located at (22, 54). This means the initial value is 22.
The rate of change is found using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Using the first two points, we have
[tex]m=\frac{69-54}{37-22}\\\\=\frac{15}{15}=1[/tex]

how to solve -6<-2x<14
Answers
-6 < -2x < 14
We're trying to solve for x. To solve for x, we must isolate x.
So, let's divide everything by -2!
-6 ÷ -2 < -2x ÷ -2 < 14 ÷ -2
**Remember : when dividing by a negative number, you MUST switch the sign! So, if the sign is ">" then we switch it to "<" and the other way around **
3 > x > -7
So, our answer is : → 3 > x > -7

7x + 3 = 9x
Simplify, isolate the x, subtract 7x from both sides
7x (-7x) + 3 = 9x (-7x)
3 = 2x
Set the equation = 0, subtract 3 from both sides
3 (-3) = 2x (-3)
0 = 2x - 3

Darnell rented a moving truck.The weight of the empty truck was 7,860 pounds.When Darnell filled the truck with his items,it weighed 6 tons.what was the weight in pounds of the items was Darnell placed in the truck? show the work
Answers
Multiply by 6.
6 ton = 12,000 lb
The problem statement tells you
(truck weight) + (Darnell's items) = 12,000 lb
7,860 lb + (Darnell's items) = 12,000 lb
Subtracting the weight of the truck gives
(Darnell's items) = (12,000 -7,860) lb = 4,140 lb
The weight of items Darnell placed in the truck was 4,140 lb.
the annual health insurance premium for Ms. Everett is $12,304 her employer says 70% of the premium and deducts the remainder from her paycheck Ms. Everett is paid monthly what amount is deducted from Ms. Everett paycheck for her health insurance premium.

$717.73
Answers
Her portion will be $3,691.20
If you spread that out over 12 months (3,691.20/12) it comes out to $307.60
To find the amount deducted from Ms. Everett's paycheck for her health insurance premium, calculate 70% of the annual premium, subtract the employer's contribution, and divide by 12 for the monthly deduction, resulting in $307.60. The correct answer is B.
To calculate the amount deducted from Ms. Everett's paycheck for her health insurance premium, first, find 70% of the annual premium:
70% of $12,304 = 0.70 x $12,304 = $8,612.80
The remainder that Ms. Everett must pay is the annual premium minus the employer's contribution: $12,304 - $8,612.80 = $3,691.20
Since Ms. Everett is paid monthly, divide the annual amount by 12 to find the monthly deduction: $3,691.20 ÷ 12 = $307.60
Therefore, the amount deducted from Ms. Everett's paycheck for her health insurance premium is $307.60.

a number is chosen at random from 1 to 50. find the probability of selecting divisors of 12
Answers
First of all, we need to know how many divisors 12 has.
12: 1, 2, 3, 4, 6, 12
Since there are 6 divisors of 12, this means the probability is 6/50.
You could just stick with 6/50 as your answer, but most probability is measured in percents so we'll convert 6/50 into a percent.
Percents are measured out of 100, so to make 6/50 into a percent we need to do some cross-multiplying.
[tex] \frac{6}{50} = \frac{x}{100} [/tex]
First, multiply 6 by 100
6 × 100 = 600
Next, divide the product by 50.
600 ÷ 50 = 12
So, your final answer is:
As a ratio:
[tex] \frac{6}{50} = \frac{12}{100} [/tex]
As a fraction:
12/100 or 6/50
As a percent:
12%

Answer:
0.8 and 1.1 are outliers of the given data set.
Step-by-step explanation:
The given data set is
5.8, 6.1, 4.9, 10.9, 0.8, 6.1, 7.4, 10.2, 1.1, 5.2, 5.9
Arrange the data set in ascending order
0.8, 1.1, 4.9, 5.2, 5.8, 5.9, 6.1, 6.1, 7.4, 10.2, 10.9
Divide the data in four equal parts.
(0.8, 1.1), 4.9,( 5.2, 5.8), 5.9,( 6.1, 6.1), 7.4, (10.2, 10.9)
From the above division we get,
[tex]Q_1=4.9[/tex]
[tex]Median=5.9[/tex]
[tex]Q_3=7.4[/tex]
The interquartile range of the data is
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=7.4-4.9=2.5[/tex]
If all the data elements lies in the interval [Q₁-1.5(IQR),Q_3+1.5(IQR)], then the data set has no outliers.
[tex][Q_1-1.5(IQR),Q_3-1.5(IQR)]=[4.9-1.5(2.5),7.4-1.5(2.5)]=[1.15,11.15][/tex]
Since all the elements lie in the interval [1.15,11.15] except 0.8 and 1.1, therefore 0.8 and 1.1 are outliers.
What is the output value for the following function if the input value is 3.2?
y = 2x - 1

5.4
Answers
The given function is y = 2x -1 which is of the form of a straight line with the form y = mx + c
now, we have been given that the value of x is 3.2 as it says input value is 3.2
we plug in x =3.2 in the equation
y = 2x -1
y = 2*3.2 -1
y = 6.4 -1
y = 5.4
So the value of y we get is 5.4
Answer = 5.4 (option D)

For graph 1, take a point (0,0).
substituting it we get,
y>4x-2 ⇒ 0>-2. This is true yet the region where (0,0) is, is shaded. So, wrong graph.
For graph 2, take point (0,0).
y>4x-2 ⇒ 0>-2. This is true but againt the region is shaded. so, wrong graph.
For graph 3, take point (0,0)
y>4x-2 ⇒ 0>-2. This is true. Since the point (0,0) is in this region, which is not shaded, it means that this is the required region. The correct graph is graph 3.

PQ bisects ∠SPY. m∠SPQ =[tex] \frac{11}{2}
[/tex] x-5 and m∠YPQ= 4x- [tex] \frac{5}{2} [/tex]
Solve for x and find m∠SPY
Answers
Since PQ bisects the angle, the two angles formed by the bisector are equal:
11/2x - 5 = 4x - 5/2
We will first multiply everything by 2 to eliminate the fractions:
(11/2x)*2 - 5*2 = 4x*2 - (5/2)*2
11x - 10 = 8x - 5
Subtract 8x from each side:
11x - 10 - 8x = 8x - 5 - 8x
3x - 10 = -5
Add 10 to both sides:
3x - 10 + 10 = -5 + 10
3x = 5
Divide both sides by 3:
3x/3 = 5/3
x = 5/3
Now we will plug this in for x in both smaller angles and add them together to find the measure of ∠SPY:
11/2(5/3) - 5 + 4(5/3) - 5/2
55/6 - 5 + 20/3 - 5/2
We will rewrite everything using a denominator of 6:
55/6 - 30/6 + 40/6 - 15/6 = (55-30+40-15)/6 = 50/6 = 8 2/6 = 8 1/3°

Which characteristics best describe an obtuse isosceles triangle? I. One angle is greater than 90°. II. All side lengths are equal. III. Two sides meet at a 90° angle. IV. Two sides are equal in length. A. I and IV B. II and III C. I and II D. III and IV
Answers
An obtuse isosceles triangle is defined as a three-sides triangle shape that has one angle (out of three angles) more than 90 degrees and whose two sides are always congruent that includes obtuse angle in between. So it will follow :-
⇒ Obtuse means "one angle is greater than 90 degrees".
⇒ Isosceles means "Two sides are equal in length".
So, option A is correct, i.e. statements I and IV.
A bargain bin contains classical and rock and CDs. There are 60 CDs in the bin. Choosing a rock CD have the same number of favorable outcomes. How many rocks CDs are in the bin
Answers
The bin should contain 30 rock CDs, which constitutes half of the total CDs (60). This conclusion is reached by dividing the total number of CDs by 2, as the question implies an equal probability of picking a rock or classical CD.
Explanation:The question pertains to the concept of probability in mathematics. Here, the total number of CDs is specified as 60. If choosing a rock CD has the same number of favorable outcomes, it means that half of the CDs are rock CDs (as the other half would then be classical CDs). So, to find the number of rock CDs in the bin, you simply divide the total number of CDs by 2. Here, 60 CDs divided by 2 equals 30. Thus, there are 30 rock CDs in the bin.
