<h2>45</h2>

Face value of 5 = 5

Face value of 9 = 9

5 × 9 = 45.

Answer:

45

Step-by-step explanation:

Because it's face values

If it was place values then it would be 5000 x 90 but since its face values it is 5 x 9 as face values is the number itself

Find the four arithmetic means between 100 and 135. Show work.
Masteriza [31]

Answer:

Please read the answers below.

Step-by-step explanation:

Let's calculate the four means between 100 and 135, this way:

1. Arithmetic mean:

(100 + 135)/2 = 117.5

2. Weighted mean:

We will assign equal weight to both numbers : 5

(100 * 5 + 135 * 5)/10 = (500 + 675)/10 = 1,175/10 = 117.5

3. Geometric mean:

√100 * 135 = √13,500 = 116.2 (Rounding to the next tenth)

4. Harmonic mean:

2/(1/100 + 1/135) = 2/(0.01 + 0.0074) = 114.9 (Rounding to the next tenth)

g Use the information below for questions 1 through 5. A San Francisco-based tech firm is able to keep 80% of its new employees
meriva

Answer:

0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year

Step-by-step explanation:

For each employee, there are only two possible outcomes. Either they survive the first year, or they do not. The probability of an employee surviving the first year is independent of other employees. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

A San Francisco-based tech firm is able to keep 80% of its new employees after one year.

This means that p = 0.8

Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year

This is P(X = 2) when n = 2. So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{2,2}.(0.8)^{2}.(0.2)^{0} = 0.64

0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year

It’s asking for the area<br> Please help me! Thank you!

<h3>Answer:   x^2+9x+8</h3>

==============================================================

Explanation:

With many math problems, a good strategy is to break things down into smaller pieces. In this case, we need to find the area of each individual smaller rectangle

A = blue rectangle area = length*width = x*x = x^2

B = purple rectangle area = length*width = x*1 = x

C = green rectangle area = length*width = 8*x = 8x

D = orange rectangle area = length*width = 1*8 = 8

Add up A through D to get the overall area of the entire or largest rectangle possible

total area = A+B+C+D = x^2+x+8x+8 = x^2+9x+8

notice how x+8x turns into 9x. You can think of it as 1x+8x = (1+8)x = 9x

This is because x and 8x are like terms which can be combined. Everything else is left as is.

Because we don't know what number goes in place for x, we cannot simplify or evaluate x^2+9x+8 any further.
