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

Step-by-step explanation:

First, let's convert feet to miles.

[tex]\dfrac{63,756 \text{ feet}}{1}\cdot \dfrac{1 \text{ mile}}{5,280 \text{ feet}}=12.075\text{ miles}[/tex]

Next, let's convert minutes to hours.

[tex]\dfrac{70 \text{ minutes}}{1}\cdot \dfrac{1\text{ hour}}{60\text{ minutes}}=\dfrac{7}{6}\text{ hours}[/tex]

Finally, let's find the unit rate.

[tex]\dfrac{12.075\text{ miles}}{\frac{7}{6}\text{ hours}}=10.35\text{ mph}[/tex]

Hope this helps!

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

"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.

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$

I don't know, man. Math isn't really my strongest suit, but I hope this helps :D

Answer:

$77

Step-by-step explanation:

Each person paid $14

Aiden+5 friends= 6 people

$14×6= $84

total cost of soda was $7

$84-$7= $77

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.

MALE                             33                          5                         38

FEMALE                         46                          6                         52

Answer:c.

Step-by-step explanation:

Answer:

?

Step-by-step explanation:

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

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.

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.

Step-by-step explanation:

Add all the numbers up and divide the total by how many numbers there are.

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!

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.
