Use the frequency table to find the probability of five or more responses received to this week's newspaper editorials.

option-B

Step-by-step explanation:

we have to find probability for 5 or more

Calculation of p(5):

number of editorials having 5 responses is 16

total number of editorials =200

so, we can find probability

Calculation of p(=>6):

number of editorials having 6 or more  responses is 6

total number of editorials =200

so, we can find probability

Calculation of p(=>5):

we can use formula

p(>=5)=p(5)+p(=>6)

we can plug values

so, answer is option-B

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
