Answer:
5 - 7
Step-by-step explanation:
a - b
5 - 7 = -2
Answer:
The amplitude = 2b, and the verticle shift = 2, which means it has been shifted down 2 units.
Step-by-step explanation:
The highest point is when y = 0 and the lowest point is when y = -4. The vertical distance between the peak and valley is 4 units, which cuts in half to 2. This is the amplitude. It's the vertical distance from the center to either the peak or valley.
I hope I helped! :)
Would appreciate Brainliest! ;)
The slope is undefined because it is a vertical line on the x axis at 0. Its a straight line going up
Answer:
He multiplied 3/4 by 1/5 instead of dividing 3/4 by 1/5.
Step-by-step explanation:
Correct is 3/4 / 1/5
= 3/4 * 5
= 15/4 gallons per minute.
Answer:
No, the confidence interval does not provide evidence that this belief is plausible as the confidence interval range contains the null value (0)
Step-by-step explanation:
Given that the confidence interval for the mean difference of AWD and FWD vehicles is :
(−0.01,0.12)
When defining the hypothesis for mean difference :
H0 : μ1 - μ2 = 0
H1 : μ1 - μ2 ≠ 0
Using the confidence interval result, reject the Null if the confidence interval value at the given α - level does not contain 0 ; otherwise fail to reject the Null ;
Since the (−0.01,0.12) contains 0 ; then we fail to reject the Null and conclude that there is no statistically significant difference between the two groups
