Explanation:
The main cluster of values is somewhere between 650 and 799, as this is where the highest bars are located. The median is somewhere in this region. The mean however is smaller than the median because the outliers to the left that pull on the mean. The outliers pull the mean toward them. Having small outliers will make the mean smaller than it should be. The median is not affected by outliers. Therefore, the median is the best measure of center in this case.
Side note: we consider this distribution to be "skewed to the left" or "negatively skewed" since the left tail is longer than the right tail.
Question 1: The sum of two consecutive multiples of 5 is 55. Find these multiples. Question 2: The present age of Sahil's mother is three times the present age of Sahil. After5 years their ages will add to 66 years. Find the present ages. Question 3: The perimeter of a rectangle is 13 cm and its width is 2- cm. Find its length.
Answer:
1] Two consecutive multiples = 50,55. 2] Sahil , Mother current age = 13,42 3] Length of rectangle = 4.5
Step-by-step explanation:
1] Let one multiple of 5 be = n. As there are two consecutive multiples, other multiple = n + 1. Given : sum of two consecutive multiples of 5 is 55
So, 5n + 5(n+1) = 55
5n + 5n + 5 = 55 ; 10n + 5 = 55 ; 10n = 50 - 5 = 50 ; n = 50 / 10 ; n = 5
n {One multiple} = 5 ; Other multiple {n+1} = 5 + 1 = 6
2] Let present age of Sahil be = x. So, present age of Sahil mother = 3x
5 years hence : (x+5) + (3x+5) = 66 {Equation 1}
Solving Eq 1} : x + 5 + 3x + 5 = 66 ; 4x + 10 = 66 ; 4x = 66 - 10 ; 4x = 56
x = 56/4 ; x = 14 {Sahil Current Age}. Mother current age = 3x = 3 x 14 = 42
3] Perimeter of rectangle = 2 (Length + Width). Perimeter = 13 , Width = 2.
So, 13 = 2 (L +2) ; 13 = 2L + 4 ; 2L = 13 - 4 = 9 ; L = 9/2 ; Length = 4.5

Solve x + 7.8 = 11.9 for x.
Answer:
4.1
Step-by-step explanation:
X+ 7.8 = 11.9
X= 11.9 - 7.8
X= 4.1
Answer:
x = 4.1
Step-by-step explanation:
To solve for x, subtract 7.8 from both sides of x + 7.8 = 11.9:
x + 7.8 - 7.8 = 11.9 - 7.8, or
x = 4.1

In this figure shown, EF is the mid segment of trapezoid ABCD. Find EF.
Answer:
x = 2
Step-by-step explanation:
EF = ½(BC + AD) => Trapezoid Midsegment theorem
Substitute
5x + 4 = ½((4x + 1) + (7x + 5))
5x + 4 = ½(4x + 1 + 7x + 5)
Multiply both side by 2
2(5x + 4) = 4x + 1 + 7x + 5
10x + 8 = 4x + 1 + 7x + 5
10x + 8 = 11x + 6
Collect like terms
10x - 11x = -8 + 6
-x = -2
Divide both sides by -1
x = 2

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

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

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.

John’s Rectangle is _____ units long.
John’s Rectangle is _____ units wide.
The area of John’s rectangle is ____ units^2.
Answer:
John's rectangle is 4 units long
John's rectangle is [tex]3\frac{1}{2}[/tex] units long
The area of John's rectangle is 14 units^2
Step-by-step explanation:
A rectangle has four sides that comprise of two pairs of equal length sides
The side which is the longest side of a rectangle is known as the length, L, of the rectangle
The side which is the shortest side of a rectangle is known as the width, W of the rectangle
Based on the given measurement, the length of the given rectangle which is the length of longest side of the rectangle, which is the 4 units length side
Therefore;
∴ John's Rectangle is L = 4 units long
the width of the given rectangle which is the length of shortest side of the rectangle, which is the side with lengths 3 units and 1/2 units length side
∴ The length of the shortest side of the rectangle, W = 3 units + 1/2 units = 3 1/2 units
∴ John's rectangle is W = [tex]3\frac{1}{2}[/tex] units wide
The area of John's rectangle, A = L × W
∴ The area of John's rectangle, A = 4 units × [tex]3\frac{1}{2}[/tex] units = 14 units².

Answer:
A) X = 8
B) X = 4.3 or 13/3
Step-by-step explanation:
A) 5x - 10 = 30
(add ten to both sides)
5x = 40
(divide by 5 on both sides)
x = 8
B) 3x + 8 = 21
(subtract 8 to both sides)
3x = 13
