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!

There are 90 penguins in a zoo. There are two types - Humboldt and Emperor.
52 are female, of these 6 are Emperor penguins.
There are 5 male Emperor penguins.
Use this information to complete the frequency tree.
Humboldt penguins
Emperor penguins
Male
Female
Humboldt penguins
Emperor penguins
Answer:
See below.
Step-by-step explanation:
Humboldt penguins; 90 - (5 + 6) = 79.
Emperor penguins: 5 + 6 = 11.
Total Male: 90 - 52 = 38.
Male Humboldt penguins: 38 - 5 = 33.
Total Female: 52.
Female Humboldt penguins: 52 - 6 = 46.
We can solve this by creating an attribute table.
HUMBOLDT EMPEROR TOTAL
MALE 33 5 38
FEMALE 46 6 52
TOTAL 79 11 90

The figure above the x-axis is the preimage. The figure below the x-axis is the image. Which transformation produced the image?
A.
reflection across the x-axis
В.
reflection about the origin
C.
rotation 90° clockwise about the origin
D.
rotation 90° counterclockwise about the origin
Answer:
Option B.
Step-by-step explanation:
From the picture attached, figure above the x-axis is the pre-image and below the axis is the image.
Let's choose a point B of the image having coordinates (0, 2).
When the point B is transformed, coordinates of the point B' is (0, -2)
And the rule for this transformation will be,
(x, y) → (-x, -y)
This rule shows the reflection of pre-image over the origin.
Option (B). will be the answer.
Answer:
B

Answer:
63$...I think
Step-by-step explanation:
if there was 5 friends and each paid 14$ the total must have been 70$. However, since the soda was 7$, then if you take away 7$ from the total, then the chicken must have been 63$

A cube with a side length of 6 feet is sliced diagonally such that it passes through the three vertices shown in the figure. Which describes the cross section?
A cube. A cross section is a triangle that touches 3 corners of the cube.
a triangle with 3 equal sides measuring 6 feet
a triangle with 3 equal sides measuring greater than 6 feet
a triangle with only 2 equal sides measuring 6 feet
a triangle with only 2 equal sides measuring greater than 6 feet
Answer:
C) a ttiangle with only 2 sides measuring 6 feet
Step-by-step explanation:
The cross section is a triangle with three equal sides measuring more than 6 feet.
What is a cube?A cube is a solid three dimensional shape with 6 faces or squares of equal length.
Analysis:
The diagonal of one face of the cube forms right angle triangle with the adjacent sides of that face of the cube.
So using Pythagoras to find length,
[tex]diagonal^{2}[/tex] = [tex]6^{2}[/tex] + [tex]6^{2}[/tex]
[tex]diagonal^{2}[/tex] = 36 + 36
[tex]diagonal^{2}[/tex] = 72
diagonal = [tex]\sqrt{72}[/tex] = 8.48 feet. Which is same form the remaining two diagonals forming the triangle.
Therefore the cross section is a triangle with three equal sides with length greater than 6 feet.
In conclusion, the cross section is a triangle with three equal sides with length greater than 6 feet.

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
please answer with the:
axis of symmetry
vertex
(explain how if you can)
Answer:
x=1
Step-by-step explanation:
X= means that it is the vertical line on that number, so x=1 would be the vertical lines going through 1, which would be in the middle of the parabola, thus having symmetry
Answer:
axis of symmetry: x = 1
vertex: (1,-4)
Step-by-step explanation:
You can find the axis of symmetry for this parabola by looking at the x coordinate for the vertex or buy looking at the graph for which x value that you can draw a line through and have symmetry on both sides.
For the vertex, you just look for the maximum of minimum (for this graph its minimum) point on the parabola.

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]

"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.

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."

Cross multiply to solve.
3*x=5*21
3x=105
x=35
The weight of the wheat flour is 35 pounds.
