What is the median of the following set of data?
0.6, 0.5, 0.9, 0.4, 0.3, 0.7, 0.2
Answer:
Median: 0.5
Step-by-step explanation:
Arrange the following set of data from least to greatest:
0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.9
then find the middle number (the median).
since there are seven numbers in the data set we divide it, by doing this:
{0.2, 0.3, 0.4} 0.5 {0.6, 0.7 0.9}
Therefore, the median for the data set is 0.5!

A rectangle with a width of 2.5 cm and a length of 3 cm is dilated by a scale factor of 4. Which statements about the new
rectangle are true? Check all that apply.
The dimensions of the new rectangle will be 10 cm by 12 cm.
The dimensions of the new rectangle will be 40 cm by 48 cm.
The new perimeter will be 4 times the original perimeter.
The new perimeter will be 16 times the original perimeter.
The new area will be 4 times the original area.
The new area will be 16 times the original area.
The new perimeter will be 44 cm.
The new area will be 30 square cm
Answer:
The new perimeter will be 4 times the original perimeter.
The new area will be 4 times the original area.
Step-by-step explanation:
The area and perimeter of new rectangle will be 120 square cm and 44 cm. Then the correct options are A, C, F, and G.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
A rectangle with a width of 2.5 cm and a length of 3 cm is dilated by a scale factor of 4.
L = 3 cm
W = 2.5 cm
Then the new dimension of the rectangle will be
W' = 4 x 2.5 = 10 cm
L' = 4 x 3 = 12 cm
Then the perimeter of the rectangle will be
P = 2(L + W)
Then the perimeter of the new rectangle will be
P = 2(4L + 4W)
P = 4 x 2(L + W)
The new perimeter is the 4 times of original perimeter.
P = 8(2.5 + 3)
P = 44 cm
The area of the rectangle will be
A = L x W
Then the area of the new rectangle will be
A = 4L x 4W
A = 16 x L x W
The new area is the 16 times of original area.
A = 16 x 2.5 x 3
A = 120 square cm
Then the correct options are A, C, F, and G.

A shopkeeper has corn flour and wheat flour. The ratio of the weight of the corn flour to the weight of the wheat flour is 3 : 5. The weight of the corn flour is 21 pounds. What is the weight of the wheat flour?
Answer:
35 pounds
Step-by-step explanation:
To solve this, we can set up a proportion.
Let's name the weight of the wheat flour "x."
3/5=21/x
Cross multiply to solve.
3*x=5*21
3x=105
x=35
The weight of the wheat flour is 35 pounds.

When Colton commutes to work the amount of time it takes him to arrive is normally distributed with a mean of 41 minutes and a standard deviation of three minutes what percentage of his commute will be between 33 and 35 minutes to the nearest tenth?
Answer:
The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%
Step-by-step explanation:
Step(i):-
Given mean of the Population(μ) = 41 minutes
Given standard deviation of the Population (σ) = 3 minutes
let 'X' be the random variable of Normal distribution
Let X = 33
[tex]Z = \frac{x -mean}{S.D} =\frac{33-41}{3} = -2.66[/tex]
let X = 35
[tex]Z = \frac{x -mean}{S.D} =\frac{35-41}{3} = -2[/tex]
Step(ii):-
The Probability that commute will be between 33 and 35 minutes to the nearest tenth
P(33≤ X≤35) = P(-2.66 ≤X≤-2)
= P( X≤-2) - P(X≤-2.66)
= 0.5 - A(-2) - (0.5 - A(-2.66)
= 0.5 -0.4772 - (0.5 -0.4961) (From normal table)
= 0.5 -0.4772 - 0.5 +0.4961
= 0.4961 - 0.4772
= 0.0189
The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%

Answer:
12a. (-6, -6)
12b. 17
13a. y = [tex]\frac{-1}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
13b. 2
Step-by-step explanation:
12a. Using the midpoint formula:
[tex](\frac{-9-3}{2} ,\frac{2-14}{2} )[/tex] = [tex](\frac{-12}{2} , \frac{-12}{2})[/tex] = (-6, -6)
12b. Using the Distance formula:
d = [tex]\sqrt{(3 - (-9))^{2} +( 14 - 2)^{2} }[/tex] = [tex]\sqrt{(12)^{2}+(12)^{2} }[/tex] = [tex]\sqrt{144 + 144}[/tex] = [tex]\sqrt{288}[/tex]
= 12[tex]\sqrt{2}[/tex] or 17
13a. x + 2y = 3
2y = 3 - x
y = [tex]\frac{-1}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
13b. The perpendicular slope is 2
A card is drawn from a standard 52-card deck. What is the probability that the card is a red card, or that it is a ten of clubs or a jack of clubs? A. 1/52 B.3 /26 C. 7/13 D.15 /26
Answer:
Step-by-step explanation:
I'm not sure whether you're asking for the probability of each condition individually or the probability of the last two together, but I'll do both.
Probability that the card is red: 26/52, aka 1/2 or 50%
Probability that the card is a ten of clubs: 1/52
Probability that the card is a jack of clubs: 1/52
Probability that the card will be either a ten of clubs or a jack of clubs: 2/52

D.)A graph with both axes unnumbered. Points are scattered loosely all Over graph.
"A Negative correlation can be defined as the inverse relationship between two variables. When one variable increases, the other decreases, and vice versa. These variables move in opposite directions from each other and the correlation between them can vary drastically over a set period of time".
For the given question,
A Negative correlation appears as a recognizable line with a negative slope. The slope of the graph shows a downtrend.
Hence we can conclude that option (C) a graph with both axes unnumbered and points showing a downward trend is the correct answer.
