I need to find the simplest form of 88 ---- 90

hram777 [196]

Given

$\frac{88}{90}$

So,

$\frac{88}{90}=\frac{2\cdot44}{2\cdot45}=\frac{44}{45}$

So, the simplest form of 88/90 is 44/45

Given EG = 16 and FH = 12, what is the length of one side of the rhombus? 6 units 8 units 10 units 14 units PLEASE HELP ONLY COM

ZanzabumX [31]

EG and FH are diagonals of the rhombus and the bisect each other at the centre to for a righ angle triangle with the side of the rhombus as the hypothenus.
By pythagoras theorem, $length = \sqrt{ 8^{2} + 6^{2} } = \sqrt{64+36} = \sqrt{100} =10 \ units$

A multiple-choice test has 30 questions and each one has five possible answers, of which only one is correct. If all answers wer

kumpel [21]

Answer: the probability is 0.13

Step-by-step explanation:

First, each question has 5 options and only one is correct.

Then, selecting at random, the probability of getting a correct answer is equal to:

p = 1/5 = 0.20 (and the probability of getting it incorrect is p = 4/5 = 0.80)

Now, if out of 30 questions, we got 4 correct and 26 incorrect, the probability for a given combination is;

p = (0.20^4)*(0.80^26)

But we also need to multiply this by the total number of combinations.

This is we have 30 questions in total, and we can select 4 of them that will be the correct ones.

Now, if we have N objects in total, the number of different combinations of K elements out of those N elements is

$C = \frac{N!}{(N-K)!*K!}$

In this case, N = 30 and K = 4.

$C = \frac{30!}{(30 -4)!*4!} = \frac{30*29*28*27}{4*3*2} = 27,405$

Then the probability of getting exactly 4 correct answers is:

P = (0.20^4)*(0.80^26)*27,405 = 0.13

Greg wants to move out of his dormitory and into an apartment near his college. His parents agreed, on the condition that the re

Harman [31]

Answer:

C. Sample: listings in a local newspaper and on an Internet sitePopulation: all available apartments near the college

Step-by-step explanation:

The sample is the set of information Greg collects to do his estimation. The sample is necessarily a subset of the population. That is, in this case, the apartments listed in the local newspaper and the internet. He will estimate a mean rent for the sample and, with this result, estimate the population mean rent.

The population is the bigger set available for Greg to do the estimation, and the set he wants to estimate a parameter from (in this case, the mean rent).

In this case, the population is all the apartments near the college.
