1/3 + 2/9 equals 3/9
3/9 is then simplified to 1/3 :)
Answer:
(1, -12)
Step-by-step explanation:
x is the horizontal axis and y is the vertical axis.
The current coordinates of D are (-5, -2).
Translated...
D = (-5 + 6, -2 - 10)
D = (1, -12)
Answer:
The answer is =15s+6
Step-by-step explanation:
3(5s + 2)
=15s+6
Answer:
Does this sample provide convincing evidence that the machine is working properly?
Yes.
Step-by-step explanation:
<u>Normal distribution test:</u>

Where,







Once the significance level was not given, It is usually taken an assumption of a 5% significance level.
Taking the significance level of 5%, which means a confidence level of 95%, we have a z-value of 
Therefore, we <u>fail to reject the null</u>. It means that the hypothesis test is not statistically significant: the average length is not different from 1.5!
Answer:
They have the same y-intercept.
Step-by-step explanation:
The y-intercept occurs when x = 0 so for f(x):
y-intercept = f(0) = -6(0) - 3 = -3.
For h(x):
y-intercept = h(0) = 2 cos(0 + pi) - 1
= 2 cos pi - 1
= 2 *-1 - 1 = -3.
