Answer:

-7.5

Step-by-step explanation:

The median is all the numbers put in order, then the middle number

Here is what that looks like:

2, -1, 11, -18, -4, 13, -11, -17, -17, -17

                        \/

-18, -17, -17, -17, -11, -4, -1, 2, 11, 13

                        \/

-18, -17, -17, -17, -11, -4, -1, 2, 11, 13

                        \/

-18, -17, -17, -17, -11, -4, -1, 2, 11, 13

                        \/

-18, -17, -17, -17, -11, -4, -1, 2, 11, 13

                        \/

Since we have two numbers in the middle

we add them together and divide by 2

                        \/

-11 + -4 = -15 / 2 = -7.5

A supervisor records the repair cost for 14 randomly selected refrigerators. A sample mean of $79.20 and standard deviation of $
Nitella [24]

Answer:

( $74.623, $83.777)

The 90% confidence interval is = ( $74.623, $83.777)

Critical value at 90% confidence = 1.645

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = $79.20

Standard deviation r = $10.41

Number of samples n = 14

Confidence interval = 90%

Using the z table;

The critical value that should be used in constructing the confidence interval.

z(α=0.05) = 1.645

Critical value at 90% confidence z = 1.645

Substituting the values we have;

$79.20+/-1.645($10.42/√14)

$79.20+/-1.645($2.782189528308)

$79.20+/-$4.576701774067

$79.20+/-$4.577

( $74.623, $83.777)

The 90% confidence interval is = ( $74.623, $83.777)

I need help with 33 and 34
kenny6666 [7]
EDIT: Picture

33) When adding matrices, just add the numbers that are in the same spot. In this problem we are given A and C, and we are asked to find B if A + B = C

So B = C - A

\left[\begin{array}{ccc}2&-1&-3\\1&4&-2\\\end{array}\right] - \left[\begin{array}{ccc}4&9&-2\\-3&5&7\\\end{array}\right] = \left[\begin{array}{ccc}-2&-10&-1\\4&-1&-9\\\end{array}\right]

34) When multiplying matrices, the number of columns in the first matrix needs to be the same as the number of rows in the second matrix. Then the outcome will have the same number of rows as the first matrix and same number of columns as the second matrix. In this case, the result will be a 2x2.

Two trays contained 12 ice cubes. How many ice cubes are there in 20 trays?
Masja [62]

If 2 trays have 12, and you need to get 20 trays, find out 2 * x = 20.

2 * 10 = 20.

So you need to multiply the problem by 10

10(2 trays = 12 ice cubes)

20 trays = 120 ice cubes.
