Answer:

The time required is 4.5 hours.

Step-by-step explanation:

A furniture manufacturing company typically takes 18 hours to assemble 12 pieces of furniture. To determine the number of pieces of furniture that will be assembled in 3 hours, the following calculations were proposed; the one that allows to verify this relationship correctly is

The 12 pieces of furniture assembled in 18 hours

So, 1 piece assembled in 18 / 12 hours = 1.5 hours  

And 3 pieces assembled in 3 x 1.5 = 4.5 hours

Help please guys I need help
omeli [17]

Answer:

= 3 + 6/15 + 10/15

Step-by-step explanation:

To make 2/5 into a fifteenth, you have to multiply the 5 by 3 to get 15. Whatever you do to the top you have to do to the bottom, meaning that you have to multiply 2 by 3 to get 6 on top.

To make 2/3 into a fifteenth, you have to multiply the 3 by 5 to get 15. Whatever you do to the top you have to do to the bottom, meaning that you have to multiply 2 by 5 to get 10 on top.

This is the same rule for all equations involving fractions.

Given that z is a standard normal random variable, find z for each situation. The area to the right of z is .1314. (Round to two
Mumz [18]

Answer:

P(Z>0.1314) = 1-P(Z

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)"  or the standard normal table

P(Z

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)"  or the standard normal table.

P(Z>0.01) = 1-P(Z

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)"  or the standard normal table

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

P(Z>0.1314) = 1-P(Z

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)"  or the standard normal table

P(Z

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)"  or the standard normal table.

P(Z>0.01) = 1-P(Z

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)"  or the standard normal table

How do you do this with decimals
ICE Princess25 [194]
Answer: x=102


Steps:

This is an isosceles triangle which mean 2 angles and 2 sides are congruent. In this case, the 3.3 sides corresponds to the 39 degree angle. This means that the other angle next to x angle is also 39 degrees.

39+39= 78

All the angles in the triangle needs to equal 180.

So subtract 78 from 180 to find the degree of x angle.

180-78= 102
