I had the same question
Answer:
Yes, Sample information does indicate that a 2-liter bottle of Pepsi contains more than 250 calories
Step-by-step explanation:
Null Hypothesis [H0] : u < 250
Alternate Hypothesis [H1] : u > 250 {One Tail}
t = (x' - u) / [ sd / √n ]
= (255 - 250) / (5.6 / √20)
5 / (5.6 /√20)
= 3.99
As t ie 3.99 > t value 1.65 ie for one tail 95% confidence level. So, we reject the null hypothesis & conclude that it contains more than 250 calories.
Answer:
(-1,6)
Explanation:
use (y1-y2), (x1-x2)
Y + 2 = -2(x - 5)
Simplify.
y + 2 = -2x + 10
Subtract 2 from both sides.
y = -2x + 10 - 2
Simplify.
y = -2x + 8 → Slope-intercept form
Our answer is the second option : y=-2x+8

Answer:
Option d. the initial amount of money placed in the savings account
Step-by-step explanation:
we have
This is a exponential function of the form
where
a is the initial value
r is the growth rate
(1+r) is the base
x is the number of years
f(x) is the amount of money in a savings account
In this problem we have
a=$3,005
r=0.03=3%
(1+r)=1.03
therefore
3,005 represent the initial value ( the amount of money for the value of x equal to zero)
