Answer:
z = 61.25, or 61 1/4
Step-by-step explanation:
This equation is a little easier to work with in the form
7 z
---- = -----
12 105
Cross-multiplying, we get 7(105) = 12z, or
12z = 735, or z = 61.25, or 61 1/4
Answer: a. N(0.92, 0.0215)
Step-by-step explanation:
For population proportion (p) and sample size n, the mean and standard deviation is given by :-
The sampling distribution model for p is given by :_
, where
We assume that the seeds are randomly selected.
Given : Information on a packet of seeds claims that the germination rate is 92%.
i.e. p= 0.92
The packet contains 160 seeds.
i.e. n= 160
Then ,
Hence, the sampling distribution model for p is:
Solution:
we have been asked to find all the possible values of the x for the given equation
This can be re-written as
Hence the required values of x are x=0, x=2/3
This isn’t an answer but we gotta see the question to answer it ☠️☠️
