The restrictions would be possible x values that could make the function equal 0.
Answer:
There is sufficient evidence to support the claim that the new balls have bounce heights with a mean different from 92.8292.82 inches, and it appears that the new baseballs are different
Step-by-step explanation:
Given that in previous tests, baseballs were dropped 24 feet onto a concrete surface, and they bounced an average of 92.82 inches
But new balls showed mean of 92.6 inches with s = 1.72 inches
Sample size = 23
Since sample size is less than 30 and population std deviation is not know we use t test

(Two tailed test at 5% significance level)
Mean difference = 
Std error of sample mean = s/sqrt n = 
Test statistic t = mean diff/std error = -3.402
df = 23-1 =22
p value = 0.002559
since p value <5% we reject H0
There is sufficient evidence to support the claim that the new balls have bounce heights with a mean different from 92.8292.82 inches, and it appears that the new baseballs are different
Answer:
B. 40 ≤ e ≤ 100
Step-by-step explanation:
In a function, the domain values are the independent variables, and are always plotted on the x-axis, while the range values the dependent variables, which are always plotted on the y-axis on a graph.
From the graph given, it shows that f is a function of e. Which is,
.
Therefore, the range of the function would be: B. 40 ≤ e ≤ 100
<h3>
Answer: 0.23</h3>
Reasoning:
There are 12 face cards since there are 3 face cards in any suit, and 4 suits. So 3*4 = 12.
There are 52 cards total.
Dividing the values leads to 12/52 = 0.230769 which rounds to 0.23
Answer:
(2,4)
Step-by-step explanation:
The formula for a circle is ( x - h )^2 + ( y - k )^2 = r^2
From this formula the center of the circle is always (h,k)
For this question h=2 and k=4 so the center of the circle would be (2,4)
