Answer:
y=-.5x+4
Step-by-step explanation:
Answer:
Null hypothesis:
B) H0: μ1 = μ2 = μ3 = μ4
Alternate hypothesis:
A) H1: At least one mean is different.
Reject H0 if F>2.74
H0 is rejected
Step-by-step explanation:
Null hypothesis always contain equality so, null hypothesis would be
B) H0: μ1 = μ2 = μ3 = μ4.
Alternate hypothesis doesn't contain equality so, alternate hypothesis would be
A) H1: At least one mean is different.
Decision rule will be "reject null hypothesis if calculated F is greater than critical value of F".
Critical value of F is F0.05(3,68)=2.74.
So, decision rule will be Reject H0 if F>2.74.
As, calculated F 2.77 is greater than 2.74 so, we reject our null hypothesis and conclude that there is sufficient evidence to suggests a difference in the means for the different types of mail at 5% level of significance.
Answer:
The light blue one -- second from the left.
x = 14 ; y = 7√2
Step-by-step explanation:
This is a right triangle. One of the angles is 45. So is the other base angle.
So one of the legs is 7√2. The other leg is also 7√2 because they are opposite equal angles.
The hypotenuse is
a^2 + b^2 = c^2
a = b
2a^2 = c^2
2 (7√2)² = c^2
2 49 * 2 = c^2
4 * 49 = c^2
c^2 = 196
c = 14
Answer:
4 yards
Step-by-step explanation:
they gained 12 yards and then lost 8
that can be expressed as 12-8=4
