aleksley [76]

Answer:

Standard error for the distribution of means = 0.4474

Step-by-step explanation:

Standard error for the distribution of means is given as

σₓ = σ/√n

where σ = standard deviation = 2.237

n = sample size = 25

σₓ = (2.237/√25)

σₓ = 0.4474

Hope this Helps!!!

Michael is 6 feet tall and is standing on top of
Evgesh-ka [11]

Answer:

79.9 feet.

Step-by-step explanation:

If you draw out the problem, you can easily visualize it.

We are given the opposite side length and the angle, and we need to find the adjacent. So, we will use tangent (soh cah toa - tangent: opposite/adjacent).

tan(53) = (100 + 6) / x

tan(53) = 106 / x

x = 106 / (tan(53))

x = 106 / 1.327044822

x = 79.87672931

Round your answer to the nearest tenth!

So, the park is approximately 79.9 feet away!

Hope this helps!

union dues are deducted from a paycheck at a rate of 4.5% of the total earnings each week if a part time employee works 20 hours
romanna [79]

First, you want to find how much the employee is making per week

In this cause, you would multiply 20 × 6

20 × 6 = 120

The employee makes $120 per week.

Then you will need to find what is 4.5% of $120.

Before you multiply, you want to move the decimal place 2 times to the left. You would end up with .045

You would multiply those two numbers

0.45 × 120 = 5.4

$5.4 is the amount of money being deducted to your sub total

$5.4 would be the dues deducted

Please help me! Determine the area
Ghella [55]

9514 1404 393

Answer:

  31.41 ft²

Step-by-step explanation:

Heron's formula is useful when you have the three side lengths.

  A = √(s(s -a)(s -b)(s -c)) . . . . sides are a, b, c and s = (a+b+c)/2

Using the given side lengths, we have ...

  s = (8 +8.4 +13.5)/2 = 29.9/2 = 14.95

  A = √(14.95(14.95 -8)(14.95 -8.4)(14.95 -13.5)) = √(14.95×6.95×6.55×1.45)

  A = √986.81399375 ≈ 31.41 . . . . square feet
