The probability that all marbles are yellow is
(7/20) (7/20) (7/20) = 343/8000
We are given
x = 2 and 3
u = 2.5
s = 0.5
Getting the z score
z = (2 - 2.5) / 0.5 and (3 - 2.5)/ 0.5
z = -1 and 1
The percentage is
1 - 0.1557 = 81.5%
Answer:
8
Step-by-step explanation:
Answer:
y = 1/3x - 1
Step-by-step explanation:
This is because the slope is rise over run. The slope is 1/3 and the y-intercept is -1

This Question is related to Direct Proportionality
Here : The Number of Miles Driven is Directly Proportional to Number of Gallons of Gas
Number of Miles ∝ Gallons of Gas
Given Keith with 16 Gallons of Gas Drove 436 Miles
⇒ Keith with 1 Gallon of Gas would Drive -
Miles
⇒ Keith with 1 Gallon of Gas would Drive : 27.25 Miles
⇒ Keith with 14 Gallons of Gas would Drive : 14 × 27.25 Miles
⇒ Keith with 14 Gallons of Gas would Drive : 381.5 Miles
