Which pair of numbers is relatively prime?

1 answer:

Kazeer [188]3 years ago

3 0

Answer: C. 625 and 81

Step-by-step explanation: A relatively prime pair is a pair in which in both numbers given, the only number that can go into each number is one. In 112 and 36, we know 2 can evenly go into each number because they both end in a positive number (112/2 is 56 and 36/2 is 18.) This means A is incorrect. As for B, 11 can evenly go into each number, leaving you with 25 and 7. B is incorrect. And then there's D. 5 can go into each number giving you 160 and 19. D is incorrect.

C is correct because the only numbers that can go evenly into 81 is 1, 3, 9, 27, and 81. None of these numbers, except one can go into 625 also.

Construct a 99% confidence interval for the population standard deviation of white blood cell count (in cells per microliter). A

kogti [31]

Answer:

The correct option is 1.148 < σ < 6.015

Explanation:

The 99% confidence interval for the standard deviation is given below:

$\sqrt{\frac{(n-1)s^{2}}{\chi^{2}_{\frac{0.01}{2} }} }$

Where:

$\chi^{2}_{\frac{0.01}{2} }=18.548$

$\chi^{2}_{1-\frac{0.01}{2}}=0.676$

Therefore, the 99% confidence interval is:

$\sqrt{\frac{(7-1)2.019^{2}}{18.548} }$

$1.148$

Therefore, the option 1.148 < σ < 6.015 is correct

A rectangular prism has a length of 114 yards, a width of 212 yards, and a height of 4 yards.

drek231 [11]

Answer: 96,672 yards cubed

Step-by-step explanation: The formula for the Volume of a rectangar prism is Length×Width×Height

114yds × 212yds × 4yds = 96,672yds^3

Its already in simplest form since its all yards

But, you can also convert it into miles

In which 1 mile = 1760 yards

So you'd divide 96670 by 1760, and what ever answer youget would be the answer in miles
