Mean is the average of the data set

Work:

Total: 3 + 3 + 3 + 4 + 6 + 6 + 7 + 8 = 40

Mean = 40/8 = 5

Explanation:

To find the mean of a data set, add all the values together and divide by the number of values in the set.

First, count the number values in your data set.

Next, sum up all values in your data set, it means you need to add all together

Last, to find mean(average) = sum of all values / total number

Professor Elderman has given the same multiple-choice final exam in his Principles of Microeconomics class for many years. After

Len [333]

Answer: 0.9738

Step-by-step explanation:

We assume that the scores follows a normal distribution.

Let $\overline{x}$ denotes the class average .

As per given we have,

$\mu=76\ \ \&\ \ \sigma=12$

Sample size : n= 12

The probability that a class of 15 students will have a class average greater than 70 on Professor Elderman’s final exam will be :

$P(\overline{x}>70)=1-P(\overline{x}$

Hence, the correct answer = 0.9738

Q ##10 please I need help with this

algol [13]

Here we are given the inequality:

$y\geq4x-5$

Let us check for each ordered pair that satisfies the given inequality.

1. (3,0)

LHS: y

here y is 0.

So LHS is 0.

RHS: 4x-5

plugging x as 3,

4(3)-5 = 7

0≥7

False

So (3,0) does not satisfy the inequality.

2. (1,1)

LHS: y

here y is 1.

So LHS is 1.

RHS: 4x-5

plugging x as 1,

4(1)-5 = -1

1≥-1

True

So (1,1) satisfy the inequality.

1. (3,4)

LHS: y

here y is 4.

So LHS is 4.

RHS: 4x-5

plugging x as 3,

4(3)-5 = 7

4≥7

False

So (3,4) does not satisfy the inequality.

1. (2,1)

LHS: y

here y is 1.

So LHS is 1.

RHS: 4x-5

plugging x as 2,

4(2)-5 = 3

2≥3

False

So (2,1) does not satisfy the inequality.

Answer: (1,1) is the solution of the given inequality.

In-s [12.5K]

Answer:

x = 11

Step-by-step explanation:

sides are proportional so you can set up a proportional and cross-multiply:

JL is to PQ as LK is to QR

x/22 = 8/16

x/22 = 1/2

2x = 22

x = 11
