Answer:
1/10
one out of ten chance
Step-by-step explanation:
3 apples + 3 peaches + 4 pears = 10 fruit
if u pick A (emphasize the "A" meaning singular) fruit at random and it comes out as an apple or peach there is 10 fruit to possibly get and u got 1 peach or apple so if u end up - nevermind u get it i'm gunnu over complicate things tell me if u understand!
i was here first so brainliest?
if u get it but up to u!
Out of the 6 answers you have, the correct answers are 1, 3, 4, and 6.

Answer:
37
Step-by-step explanation:
The first thing is to calculate critical z factor
the alpha and the critical z score for a confidence level of 90% is calculated as follows:
two sided alpha = (100% - 90%) / 200 = 0.05
critical z factor for two sided alpha of .05 is calculated as follows:
critical z factor = z factor for (1 - .05) = z factor for (.95) which through the attached graph becomes:
critical z factor = 2.58
Now we have the following formula:
ME = z * (sd / sqrt (N) ^ (1/2))
where ME is the margin of error and is equal to 6, sd is the standard deviation which is 14 and the value of z is 2.58
N the sample size and we want to know it, replacing:
6 = 2.58 * (14 / (N) ^ (1/2))
solving for N we have:
N = (2.58 * 14/6) ^ 2
N = 36.24
Which means that the sample size was 37.
