123,456 is not divisible by which of the following numbers? 3,4,5,6

1 answer:

8 0

The answer is 5 because for it to be divisible by 5 the number needs to end in 0 or 5.
Also 3 goes into that number 41152
4=30864
6= 20576
5= 24691.2
because of the .2 at the end it is not divisible.

so the answer is 5

jasenka [17]

Answer:

-27/7

Step-by-step explanation:

Replace x with 19,

f(19)=3/(19+2) - root(19-3)

=3/21 - root(16)

=1/7 - 4

=1/7 - 28/7

= -27/7

Use the given data to find the 95% confidence interval estimate of the population mean μ. Assume that the population has a norma

loris [4]

Answer: For 95% Confidence Interval:

Upper Limit = 110.2

Lower Limit = 97.8

95% Confidence Interval = [97.8, 110.2]

Step-by-step explanation:

Given that,

Mean(M) = 104

Standard Deviation(SD) = 10

Sample Size(n) = 10

Formula for calculating 95% Confidence Interval are as follows:

Standard error(SE) = $\frac{SD}{\sqrt{n} }$

= $\frac{10}{\sqrt{10} }$

= 3.164

⇒ M ± $Z_{0.95}$ × SE

= 104 ± (1.96)(3.164)

= 104 ± 6.20

∴ Upper Limit = 104 + 6.20 = 110.2

Lower Limit = 104 - 6.20 = 97.8

So,

95% Confidence Interval = [97.8, 110.2]
