Simplify square root of ten times square root of eight.
Romashka-Z-Leto [24]
<h2>Explanation:</h2><h2></h2>

Here we need to simplify the square root of ten times square root of eight, so let's write this step by step:

Step 1. The square root of ten

\sqrt{10}

Step 2. The  square root of eight

\sqrt{8}

Step 3. The square root of ten times square root of eight

\sqrt{10}\times \sqrt{8} \\ \\ \\ \text{From radical property:} \\ \\ \sqrt{a}\times \sqrt{b}=\sqrt{ab} \\ \\ \\ So: \\ \\ \sqrt{10}\times \sqrt{8}=\sqrt{80} \\ \\ \\ But: \\ \\ \sqrt{80}=\sqrt{16\time5}=\sqrt{16}\sqrt{5}=4\sqrt{5}

Finally, the correct option is:

<em>Four square root of five</em>

An online instructor sends updates to students via text. The probability model describes the number of text messages the instruc
alexandr402 [8]

Answer:

The expectation the instructor to send each day

E(X) = 3.65

Step-by-step explanation:

Given data   x   :    0      1           2        3         4        5

P(X=x)               :   0.05 0.05    0.1    0.1         0.4     0.3

The given data satisfy the two conditions

I) Given all probabilities are p₁(x) ≥0

ii) sum of all probabilities is equal to one

0.05 + 0.05 + 0.1  +  0.1 + 0.4 +0.3 =1

Therefore given data is discrete probability distribution

<u>Expectation</u> :-

suppose a random variable X assumes the values x_{1}, x_{2},..x_{n} with respective probabilities p_{1}, p_{2},..p_{n} , then the Expectation or Expected value of X  , denoted by E(X) = ∑pi xi

E(X) = 0X0.05+1X 0.05 +2X 0.1  +3X 0.1 +4X0.4 +5X 0.3

on simplification, we get

E(X) = 3.65

Aleonysh [2.5K]

Answer:

Step-by-step explanation:

to set a spreadsheet on excel, you start with the category labels on the top row, then you go down in columns. Then you enter the scores that you want for each category . after you are done with entering the scores, you found the average percent of each category by dividing the total amount of scores by the number of score in one cell . For Example, the total score was 1530 and there was 20 , you got 76.5%. you continue this for each category. Then multiplied it by the category weights. Finishing it off, I added each categories’ answers up and got my final grade of 76.5%. The letter grade this student got was a C.(google spread sheet)
