Answer 2

Answer:

5. B, 21

6. C, 16

Step-by-step explanation:

5. 11 - 11 = 0, |0| = 0

33 - 12 = 21, |21| = 21

0 + 21 = 21

6. -3 [tex]\frac{1}{2}[/tex] - 2 = -5 [tex]\frac{1}{2}[/tex], |-5 [tex]\frac{1}{2}[/tex]| = 5 [tex]\frac{1}{2}[/tex]

13 [tex]\frac{1}{2}[/tex] + -3 = 10 [tex]\frac{1}{2}[/tex], |10 [tex]\frac{1}{2}[/tex]| = 10 [tex]\frac{1}{2}[/tex]

5 [tex]\frac{1}{2}[/tex] + 10 [tex]\frac{1}{2}[/tex] = 16

Phil and his family want to do something fun and memorable on Leap Day. They each come up with an activity: attend a trapeze class, go fishing, go on a hike, or visit a theme park. They settle on picking the letters L, E, A, and P from a bowl, replacing them after each pick, to make the decision. They repeat this experiment 40 times to verify their model and record the results in this table.
Below is the chart
Activity Letter Times Picked
trapeze class L
10
fishing E
11
hiking A
9
theme park P
10

Based on the results in the table, is this model a fair representation for choosing an activity?
A.
No, it is an unfair model because the outcomes have different frequencies.
B.
No, it is an unfair model because the relative frequency of the letter E is the highest.
C.
Yes, it is a fair model because the relative frequencies of the letters L and P are equal.
D.
Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

Answers

Answer:

D. Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

Answer:

Step-by-step explanation: I don’t know the answer but if you don’t know what the median and mean is I’ll tell you.

Mean: is the average of the numbers.

Median: The middle number found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1 , 4, 7) , the number 4 is in the middle.

Tina is packing for a five-day trip. She has one blue, one red, one white, one green, and one grey t-shirt. Tina will not wear each t-shirt more than once. What is the probability that Tina will wear blue on the first day of her trip and then wear grey on the second day of her trip?

2/5

1/5

1/20

1/25

Answers

the answer is 1/5 because there’s 5 shirts but a 20% change which is also 1/5 she’ll pick the blue one.

The probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

The probability of Tina wearing blue on the first day of her trip is 1/5, since she has 5 t-shirts to choose from and only one of them is blue.

After wearing the blue t-shirt on the first day, Tina will have 4 t-shirts left to choose from for the second day. Only one of those t-shirts is grey, so the probability of Tina wearing grey on the second day given that she wore blue on the first day is 1/4.

The probability of both events happening (Tina wearing blue on the first day and then grey on the second day) is the product of the individual probabilities:

P(blue on first day and grey on second day) = P(blue on first day) x P(grey on second day | blue on first day)

P(blue on first day and grey on second day) = (1/5) x (1/4)

P(blue on first day and grey on second day) = 1/20

Therefore, the probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20. So, the correct option is 1/20.
