10. As 8x = 2x + 60. So x =10
Answer:
24 for estimate, the accurate is 25.2
Step-by-step explanation:
surveyed total = 30
9 = run 5> days a week
84 = total members
9/30 = percent of members who run 5> days a week
9/30 => 3/10
percent of members who run 5> days a week * total members = number of members who run 5> days a week
3/10 x 84 = 25.2 members
84 = 80
3/10 x 80 = 24
24, a reasonable estimate for the number of Freemont Run Club members who run more than 5 days a week.
Answer:
The probability is 0.000000207176
Step-by-step explanation:
In this question, we are asked to calculate the probability that if 6 cards are selected from a deck of cards, we will be having 4 kings and 2 queens.
Before we answer, we should understand that in a deck of cards, there are 4 queens and 4 kings. The probability of selecting a king is the same as the probability of selecting a queen which is 4/52 = 1/13
Okay now we want to find the probability of the six cards being 4 kings and 2 queens. Since the probabilities are equal, we proceed to calculate at the same time.
That would be (1/13)^6 = 0.000000207176
The probability of selecting 4 kings and 2 queens is 0.000000207176

Step-by-step explanation:
Answer:
the length of the arc EG = 15.7 feet
Step-by-step explanation:
∵m∠EOG = 60°
∵ measure circle 360°
∴ 
∴ The length of the intercepted arc EG is 1/6 the length of the circle
∵Length circle = 2 π r
∴ Length arc EG = 
× 2 × 3.14 × 15 = 15.7 feet
