The two intervals (114.3, 115.1) and (114.0, 115.4) are confidence intervals (computed using the same sample data) for μ = true average resonance frequency (in hertz) for all tennis rackets of a certain type.
(a) what is the value of the sample mean resonance frequency? (hint: where is the confidence interval centered? )
b) the confidence level for one of these intervals is 90% and for the other it is 99%. which one has a confidence level of 99%?
(114.0, 115.4)(114.3, 115.1)

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

the answer is 45 i just did it on oddesy ware

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

the answer is b
