P(M or P)

What's the probability?

Answers

Answer 1

Answer:

P(M) + P(P)

Step-by-step explanation:

In general, for two mutually exclusive events A and B, P(A occurs or B occurs) = P(A or B) = P(A) + P(B)

Thus, P(M or P) = P(M) + P(P)

A fair coin is flipped 20 times. If the coin lands on
heads 13 times, which statement is true?
A. The coin lands on heads 3 less times than
expected.
B. The coin lands on heads 3 more times than
expected.
C. The coin lands on heads 5 less times than
expected.
D. The coin lands on heads 5 more times than
expected.

Answers

B because it’s a 50% chance of getting heads/tails and it landed 13 times out of 20 on heads so 3 more then 50% of 20
b because the coin has a 50% chance to land on heads or tails. Which means if its flipped 20 times it has a 50% chance to land on heads which is 10 times. The coin landed on heads 13 tikes which is 3 more than 10

Rosa throws a ball. The equation d = −t^2 + 4t + 5 represents the path taken by Rosa's ball where d is the height of the ball (in feet) after t seconds. How long was the ball in the air?

A. 1 second
B. 4 seconds
C. 5 seconds
D. 9 seconds

Answers

Answer:

B

Step-by-step explanation:

-t²+4t+5=0

t²-4t-5=0

t²-5t+t-5=0

t(t-5)+1(t-5)=0

(t-5)(t+1)=0

t=5,-1

when t=0,d=5

actual time it it is in air=5-1=4 seconds.

Nadia's grades on four quizzes were 95, 75, 85, and 95. Find the mean, median, and mode for Nadia's grades. ​

Answers

Answer:

mean: 87.5

median: 80

mode: 95

What is mean? : the sum of a collection of numbers divided by the number of numbers in the collection so for this is:

95+75+85+95= 350 divided by 4 because there's 4 numbers = 87.5 which is the mean

What is median?: The median is the value separating the higher half of a data sample so for this think of crossing each number at the opposite sides: 95 and 95 cancel now your left with 75 an 85 add them up and divide by 2 because there's 2 numbers **for median you are either left with 1 number or 2 if the case is 2 you ADD first then divide by 2 ALWAYS**: 75+85= 160/2= 80 for median

What is mode?: The mode is the value that appears most often in a set of data. So as we know 95 repeats the most

First u want to order the numbers from greatest to least 95,95,85,75
Mean: all numbers added up then divided by the number of numbers u have. So 95+95+85+75= 350 divided by 4 = 87.5
Mean=87.5
Median: the middle number. So after the numbers r ordered from greatest to least take one number off each side until u get to the middle. In this case there are two middle number 95 and 85 so u add them then divide by 2 95+85= 180 divided by 2= 90
Median= 90
Mode: the number that repeats most in the set of numbers. In this case the mode is 95 because there r 2 95s
Mode: 95

Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.

Answers

Answer:

Inequality: .80x +21 ≤ 82

Answer: 76.25 miles in total

Step-by-step explanation:

Hi,

An inequality to represent this is .80x +21 ≤ 82

(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).

Now we solve...

.80x + 21 ≤ 82

Subtract 21 on both sides...

.80x ≤ 61

Now, divide by .80 on both sides...

x ≤ 76.25

He can drive up to 76.25 miles in total

Hope this helps :)

Step-by-step explanation:

Number of diagonals of a polygon

(where 'n' is the number of sides)

[tex] = \frac{n \times (n - 3)}{2} [/tex]

so the 3 points you have are (-1,-9) (3,11) (5,21)

so i'm going to choose (3,11) and (5,21) 3 is x1 11 is y1
