Answer:
Step-by-step explanation:
This is a two tailed test for comparison of two variances at 2% significance level
deg of freedom = 7
F statistic =
p value = 0.4496
1. State the decision rule for 0.02 significance level. (Round your answer to 1 decimal place.) Reject H0 if F >10.4555
2.F=2.041
3. _Accept_________H0. There is __no significant____ in the variations of the two populations
Answer:
D
Step-by-step explanation:
If we use the calculator will find out that x= √151/2 ≈ 6.1441
D. 6 < x < 7
x is less then 7 and greater than 6
Without the calculator you can think that 151 is almost 144 that is 12² so
we can approximate √151 to be a bit more then 12
√151/2 = a bit more then 12 /2 = 6 and a bit more
Sarah: School to mall = 21
mall to library = 20
Total distance for Sarah = 20 + 21 = 41 miles.
Use the Pythagorean theorem to find the distance Bret traveled:
Distance = SQRT(21^2 + 20^2)
= sqrt(441 + 400)
= sqrt(841)
= 29 miles
Total distance = 41 + 29 = 70 miles
Answer is D. 70 miles.
Answer:
A is graph 3
B is graph 1
C is graph 2
Step-by-step explanation:
A is graph 3 because it’s says that she begins with at least a total of 80 os the y should not start at 0, instead it should, start at 80 but every time she gets a question wrong the graph keeps going down.
B is graph 2 because it States that Heath has 10 pennies to begin with so the y isnt 0 but 10 and every time she doubles it the graph only goes up.
C is graph 1 because it states that to Exeter a school fair it’s 5 bucks but each ticket cost 50 cents so it starts at 5 then keeps going up.
(I’m 100% sure of A but I’m not really sure about B and C but this is my best guess)
