Find the smallest integer k such that 60k is aperfect square​

Mathematics

Travka [436]3 years ago
5 0

Answer:  k = 15

<u>Step-by-step explanation:</u>

60 times some number k must be a perfect square.

Factor 60 to see which values do not have a pair:

60 = 2 · 2 · 3 · 5   --> 60 =<u> 2 · 2</u> · 3 · 5

                                                        ↓

                                                     3 · 5   are not pairs

So,  you need to multiply 60 by 15 to make a perfect square

60 × 15 = 900      →          \sqrt{900}=30

10^2+24^2=c^2

100+576=c^2

676=c^2

c=√676

c=√169×4

c=13×2

In order to help identify baby growth patterns that are unusual, we need to construct a confidence interval of the mean head cir
sukhopar [10]

Answer:

The 99% confidence interval estimate of the mean head circumference of all 2-month-old babies is (40.18cm, 41.02cm).

Step-by-step explanation:

Our sample size is 100.

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

df = 100-1 = 99.

Then, we need to subtract one by the confidence level \alpha and divide by 2. So:

\frac{1-\alpha}{2} = \frac{0.01}{2} = 0.005

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 99 and 0.005 in the t-distribution table, we have T = 2.626

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

s = \frac{1.6}{\sqrt{100}} = 0.16

Now, we multiply T and s

M = Ts = 2.626*0.16 = 0.42

For the lower end of the interval, we subtract the sample mean by M. So the lower end of the interval here is

L = 40.6 - 0.42 = 40.18cm

For the upper end of the interval, we add the sample mean and M. So the upper end of the interval here is

L = 40.6 + 0.42 = 41.02cm

So

The 99% confidence interval estimate of the mean head circumference of all 2-month-old babies is (40.18cm, 41.02cm).
