Answer:45cm

Explanation: If the whole paper is 12 by 15 you have to divide them both by 2!
12 divide by 2=6
15 divide by 2=7.5
Then you have to multiply them together to find the area.
6x7.5=45
So therefore the answer is 45cm.

Suppose the weekly amount of money spent on maintenance and repairs by a company is NOT approximately normally distributed. Howe
UNO [17]

Answer:

Probability = 0.00621

Step-by-step explanation:

We are given;

Population mean; μ = 400

Population standard deviation; σ = 20

Raw score; x¯ = 450

the probability that the actual costs will exceed the budgeted amount will be the p-value.

Thus, let's first find the z-score after which we will find the p-value.

z = (x¯ - μ)/σ

z = (450 - 400)/20

z = 50/20

z = 2.5

From online p-value from z-score calculator attached, using z = 2.5; one tailed hypothesis; significance level of 0.05, we have;

P-value = 0.00621

The triplets, nick, Brian, and dan, exit their preschool classroom every day in a random order. Create an organized list to show
AfilCa [17]

The set of all possibilities is called sample space and is denoted by S.

So, S = {NBD, NDB, BDN, BND, DBN, DNB} and n(S) = 8

and we need to find the probability of NBD

E = {NBD} and n(E) = 1

The probability of an even is defined by p(E) = \frac{n(E)}{n(S)}

Hence,  p(E) = \frac{1}{8}

A British company is sending you measurements for a table to build in your factory. The table top must be 50 cm × 75 cm. Your ma
IRINA_888 [86]

<u>Answer:</u>

19.5 x 29.25 inches

<u>Step-by-step explanation:</u>

We are given that the top of the table, which we are to build in our factory must of the the dimension 50 cm x 75 cm.

Also, out machine is calibrated in inches. So to find the size of the table in the inches, we need to multiply the given dimensions of the table top with the scale (1 cm = 0.39 inches)

50 cm ---> 50 x 0.39 = 19.5 inches

75 cm ---> 78 x 0.39 = 29.25 inches

Therefore, the dimensions of the table in inches are 19.5 x 29.25 inches.
