Answer:

P(Sports|Senior)= 0.71

Step-by-step explanation:

Hello!

You have a two-way table with the information describing students after school activities regarding the grade the student is in.

You have to calculate the probability that a randomly selected student is ins sports given that he is a senior.

This is a conditional probability and you can symbolize it as:

P(Sports|Senior)

Using the definition of the conditional probability we know that:

P(Sports|Senior)= \frac{P(Sports n Senior)}{P(senior)}

The probability of the intersection of both events "Sports" and "Seniors" can be calculated as the number of students that are in senior years and take sports by the total of students in the sample

P(Sports ∩ Senior)= \frac{25}{100}= 0.25

The probability of the student being a senior is a marginal probability, you can calculate is as the number of observed students that are in senior year by the total number of students:

P(senior)= \frac{35}{100} = 0.35

Now you can calculate the asked probability

P(Sports|Senior)= \frac{P(Sports n Senior)}{P(senior)}= \frac{0.25}{0.35} = 0.71

I hope this helps!

A scientist has collected the following data on the population of a bacteria colony over a thirty-minute period:

5 minutes: 78,000

10 minutes: 234,000

15 minutes: 657,000

20 minutes: 1,784,000

25 minutes: 5,040,000

30 minutes: 14,980,000

Which type of graph would be best to use to display the growth of the colony?

A.) a bar graph

B.) a circle graph

C.) a histogram

D.) a line graph

\huge \bold \red{Answer}

An bar graph suits the best in this type of study because we can easily understand the growth and decrease of that particular thing which is being studied.

Can you use the Associative Properties with subtraction and division? Use (14 - 8) - 2 and 24/(4/2 to explain.
larisa86 [58]
No, you cannot use the Associative properties with either subtraction and division, because it will not end to the same result. 14-8 is not the same as 8-14, and 24/4 is not the same as 4/24, but for example 3+2 is the same as 2+3.

PLS PLS HELP!!! I NEED THIS DONE PLS!!!

The domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.

<h3>The domain and the range</h3>

The domain is the set of input values i.e. the ∅ values.

On the table, we can see that the ∅ value is from 0 to 2π.

This means that the domain is 0 ≤ ∅ ≤ 2π

On the other hand, the range is the set of output values i.e. the cos(∅) values.

On the table, we can see that the cos(∅) value is from -1 to 1.

This means that the range is -1 ≤ cos(∅) ≤ 1

Hence, the domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.

<h3>The graph of the function</h3>

use the properties of equality to show that the equation 6x + 3 = 27 is equivalent to the equation 2x = 8.
MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

The equation 6x + 3 = 27 is equivalent to 2x = 8 because you can divide 8 by 2x to get X=4. To solve 6x + 3 = 27, you can subtract 3 to both sides of the equal sign to end up with 6x = 24, and from there you can divide 24 by 6x and also end up with X = 4. Both equations have the same answer.
