Answer:
a) I donot agree with him because as we see the sequence nicely we will find an interval of 8 between any two terms and 32 and 33 don't match them
Step-by-step explanation:
b) and c) Solution:
Given,
First term (a) = 4
Common difference (d) = 12-4 = 8
Now,
Since, they are in A.P.
nth term = a + (n-1)d
= 4 + 8(n-1)
= 4 + 8n-8
= 8n-4
Again,
1st method for c)
100th term = a + 99d = 4 + 99*8 = 4 + 792 = 796
200th term = a + 199d = 4 + 199*8 = 4 + 1592 = 1596
2nd method for c)
100th term = 8*100 - 4 = 800 - 4 = 796
200th term = 8*200 - 4 = 1600 - 4 = 1596
Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 8 dogs and made a total of $49. How
many small dogs did Ryan walk?
Answer:
5
Step-by-step explanation:
There are no multiples of 5 or 8 that would end with 9. But if he walks 3 large dogs he gets 24 dollars. if he walks 5 small dogs thats an additional 25 dollars. so he would make 49 dollars.

Which expression is equivalent to the expression for the perimeter of the larger garden. Select all the apply.
Answer:
Option A, 4X + 40 expression is equivalent to the expression for the perimeter of the larger garden
Step-by-step explanation:
The complete question is
A garden is 15 feet long by 5 feet wide. The length and width of the garden will each be increased by the same number of feet. This expression represents the perimeter of the larger garden: (x+15)+(x+5)+(x+15)+(x+5). Which expression is equivalent to the expression for the perimeter of the larger garden? Select all that apply.
4x+40 2(2x+20) 2(x+15)(x+5) 4(x+15)(x+5) 2(x+15)+2(x+5)Solution
The expression for the perimeter of the larger garden: [tex](x+15)+(x+5)+(x+15)+(x+5)[/tex]
If the given expression is expanded and solved, we get the following
[tex](x+15)+(x+5)+(x+15)+(x+5)\\X+X+X+X + 15+15+5+5\\2X+2X+30+10\\4X +40[/tex]
Hence, option A is correct

Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G(1,3), H(2,1), J(-1,-5), and K(-2,-3).
Answer:
the answer is (0,-1)
Step-by-step explanation:
The Midpoint of G(1,3) and H(2,1)= (3/2, 2)
The midpoint of J(-1,-5) and K(-2,-3)= (-3/2, -4)
The midpoint of both (3/2 ,2) and (-3/2, -4)= (0,-1)

y = 45x + 15
Step-by-step explanation:
Given :
Days Total Cost
(d) (C)
2. $105
4 $195
6 $285
10 $465
The daily rate is the slope :
Slope = Rise / Run
Slope = (y2 - y1) / (x2 - x1)
Slope = (465 - 105) / (10 - 2)
Slope = 360 / 8
Slope = 45
Daily rate = $45
Using the slope intercept relation :
y = mx + c
m = slope, c = intercept
105 = 45x + c
105 = 45(2) + c
105 = 90 + c
105 - 90 = c
15 = c
Pricing plan :
y = 45x + 15
Answer is 45 because if you divide 90/2 it equal 45

Answer:
A = 5 units²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂
d₁ = x + 4 = 1 + 4 = 5
d₂ = 2y - 4 = 2(3) - 4 = 6 - 4 = 2 , then
A = [tex]\frac{1}{2}[/tex] × 5 × 2 = 5 units²
Answer:
A= 5m
Step-by-step explanation:
The equation to find the area of a rhombus, when knowing the diagonals, is:
1/2×d1×d2To solve this, we have to find first d1 and d2, which are marked in a parenthesis:
d1= (x+4)m, where x=1d1= 5md1= 5m. Now, let's find d2:
d2= (2y-4)m, and y=3d2= (6-4)md2= 2mKnowing the values of both diameters, we can solve the equation for the area:
A= 1/2×d1×d2A= 1/2×5m×2mA= 1/2×10mA= 5mThe area of the rhombus is 5 meters.
Hope it helps!!

Answer:
124°
Step-by-step explanation:
measure of arc DC = 44 because the measure of central angle equals the measure of its arc.
measure of arc CB = 80 because the measure of central angle equals the measure of its arc.
measure of arc DC = measure of arc DC + measure of arc CB
= 44 + 80 = 124°

So you see that it says Find the probability that the sum on the two dice is 4 given that the sum is even. So that means that it would be 2 dices that have rolled a 4 and the equation would be 2×4= 8, So that means that you want to write the answer which is 8 in a fraction, and 8 in a fraction is 8/1
A scale of 1 cm to 8 km is used for a map.
(i) If a forest has an area of 5 cm² on the map, find its actual area.
(ii)
If the actual area of a park is 128 km², calculate its area on the map.
Answer:
40 km^2
16 cm^2
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Actual area = scale factor x scaled area
8 x 5 = 40 km^2
Scaled area on the map = 128.8 = 16 cm^2

Mr.russo exchanged 200 euros for 270 dollars how many dollar he get foe 300 euros
Answer:
$405
Step-by-step explanation:
This is a proportion problem!
Build fractions that have euros on top and dollars on the bottom (or the other way around, you decide, but make it the same in both fractions).
Let's do euros over dollars.
Setup:
[tex]\frac{200}{270}=\frac{300}{d}[/tex]
"Cross multiply."
[tex]200d=300\times 270\\\\200d=81000\\\\d=\frac{81000}{200}=405[/tex]

D. A = x² + 44x = 808Step-by-step explanation:
Check if the relationship is linear. Verify the difference between areas.
We can see the difference is not common.
It means we can exclude options B and C.
The remaining options are quadratic (A and D).
Try the last column with option A:
4813 = 45² + 19084813 = 3933FalseVerify the last option:
4813 = 45² + 44*45 + 8084813 = 4813CorrectWe can check and confirm the other columns are correct as well.

State study on labor reported that one-third of full-time teachers in the state also worked part-time at another job. For those teachers, the average number of hours worked per week at the part-time job was 13. After an increase in state teacher salaries, a random sample of 400 teachers who worked part-time at another job was selected. The average number of hours worked per week at the part-time job for the teachers in the sample was 12.5 with a standard deviation of 6.5 hours. Is there convincing statistical evidence, at the level of α=0.05, that the average number of hours worked per week at part-time jobs decreased after the salary increase?
(A) No. The p-value of the appropriate test is greater than 0.05.
(B) No. The p-value of the appropriate test is less than 0.05.
(C) Yes. The p-value of the appropriate test is greater than 0.05.
(D) Yes. The p-value of the appropriate test is less than 0.05.
(E) Not enough information is given to determine whether there is convincing statistical evidence

Answer:
B - No. The p-value of the appropriate test is less than 0.05
Step-by-step explanation:
I found it online in some answer key pdf
From the solution to the question that we have here, the answer is A. There is no convincing evidence that the hours worked decreased after the increase in salary.
The hypothesis formulationH0: u = 13
H1: u < 13
sample size n = 400
bar x = 12.5
mean = 13
How to solve for the t test statistics[tex]t = \frac{x-u}{s/\sqrt{n} } \\\\t = \frac{12.5-13}{6.5/\sqrt{400} } \\[/tex]
= -1.5388
degree of freedom: 400 -1 = 399
∝ = 0.05
Find the p value
p(t < -1.5385)
= 0.062
The p value is greater than the level of significance. We therefore fail to reject the null hypothesis.
