Answer:

C

Step-by-step explanation:

i think

The required work done is 38.82 joules.

Work done to be determine for force of 10 newton on angle of 75° for 15 meters.

What is work done?

Work done is define as the force required to move an object by some displacement.

Here, work done = force x displacement x cosФ
                          =  10 x 15 x cos75°
                          =   150 x 0.25

                           = 38.82 joules

Thus, the required work done is 38.82 joules.

there are two ways you can do this. Go through each of the nth terms separately and find the one that matches or you can find the nth term with the sequence itself.

so you find the size difference inbetween each term which is -5 so you know there will be -5n in your formula so then you need to make n= 1 (for the first term) so that equals -5 but you want -3 so you need to find what + -5 equals -3 which is 2.

So now you know your answer is 2-5n

Step-by-step explanation:

Step 1: Define equation

5x - (x + 4) + 1 = 3 - 2(x + 6)

Step 2: Solve for x

Distribute:                          5x - x - 4 + 1 = 3 - 2x - 12Combine like terms:          4x - 3 = -2x - 9Add 2x on both sides:      6x - 3 = -9Add 3 to both sides:         6x = -6Divide both sides by 6:     x = -1

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                    5(-1) - (-1 + 4) + 1 = 3 - 2(-1 + 6)Parenthesis (Add):        5(-1) - 3 + 1 = 3 - 2(5)Multiply:                        -5 - 3 + 1 = 3 - 10Subtract:                       -8 + 1 = -7Add:                              -7 = -7

The manager of a garden store decides to hold a Buy 3, Get 1 Free sale on vegetable plants. The sale is held for one week and a total of 636
vegetable plants were sold (not including the ones given away for free). If each plant cost the store $2.90, how much money did the store lose
by giving away the free plants?

Answers

Answer:

the shop lost $922.20 by giving away free vegetable plants.

Step-by-step explanation:

you would start by dividing 636 by two to see how many free vegetable plants were given away.

636 / 2 = 318

this shows us how many free vegetable plants were given for free, so then to find how much money the store lost giving them away for free, you would multiply 318 by 2.9

318 x 2.9 = 922.2

Therefore the shop lost $922.20 by giving away free vegetable plants.

the amount of sleep that elementary school children get per night follows a normal distribution with a mean of 9.5 hours and a standard deviation of 0.55 hours. is it unusual for an elementary student to get at least 12 hours of sleep?

Answers

Answer:

Yes, that is unusual as the problem is given.

Step-by-step explanation:

If the mean is 9.5 and the standard deviation is 0.55, then anything within the normal curve of 10.05 on the high end and 8.45 on the low end is normal. 12 is more than several standard deviations or an outlier if this makes sense.

So, it is unusual as the problem is stated, but if it's a weekend, 12 hours is normal. LOL

Good luck!  

Based on the normal distribution parameters given, the probability of a student getting atleast 12 hours of sleep ls 0. Hence, it is abnormal.

Given the Parameters :

Mean = 9.5 Standard deviation = 0.55

Using the Zscore formula, the probability of getting a atleast 12 hours of sleep can be expressed thus :

Zscore = (Score - Mean) / standard deviation

For X ≥ 12 :

Z = (12 - 9.5) / 0.55 = 4.545

The probability using a normal distribution table :

P(Z ≥ 4.54) = 1 - P(Z ≤ 4.54)

P(Z ≤ 4.54) = 1 ( normal distribution table)

P(Z ≥ 4.54) = 1 - 1 = 0

Since, the probability is 0 ; hence, it is unlikely and therefore, abnormal.
