Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length of the rectangle:

W is the width of the rectangle.

Given

Perimeter = 214feet

If the length is 41 ft longer than the width, then L = 41+W

Substitute L = 41+W into the formula:

P = 2(L+W)

214 = 2(41+W+W)

214 = 2(41+2W)

214 = 82+4W

4W = 214-82

4W = 132

W = 132/4

W = 33 feet

Since L = 41+W

L = 41+33

L = 74 feet

Hence the dimension of the field is 74ft by 33ft

<em>The width of the playing field is 33feet</em>

See image for question.<br><br>Please show workings and diagrams.​
Komok [63]

Answer:

  • a) 258 km
  • b) 267°
  • c) 87°

Step-by-step explanation:

  • <em>Refer to attached diagram (not to scale).</em>
  • <em>Given details are reflected.</em>

<u>First find the measure of angle Q</u>

  • m∠Q = 36° + (180° - 125°) = 91°

a) <u>Use law of cosines to find x:</u>

  • x = √(160² + 200² - 2160*200*cos 91°) = 258 km (rounded)

<u>Use the law of sines to find the missing angles:</u>

  • 258 / sin 91 = 160 / sin R = 200 / sin P
  • m∠R = arcsin (160 sin 91° / 258) = 38°
  • m∠P = 180° - (91° + 38°) = 51°

b) <u>Bearing P from R:</u>

  • 360° - (55° + 38°) = 267°

c)  <u>Bearing R from P:</u>

  • 36° + 51° = 87°

Use the formula to find the standard error of the distribution of differences in sample means, x¯1-x¯2. Samples of size 100 from
garri49 [273]

Answer:

standard error = 2.11

Step-by-step explanation:

First we stablish the data that we have for each sample:

<u>Population 1</u>                                          <u>Population </u>2

n₁ = 100                                                     n₂ = 90

x¯1= 95                                                    x¯2 = 75

σ₁ = 14                                                        σ₂ = 15                  

To calculate the standard error of each sample we would use the formulas:

σ = σ₁/√n₁

σx¯2 =  σ₂/√n₂

Now, in order to obtain the standard error of the differences between the two sample means we combine those two formulas to obtain this:

σx¯1 - σ x¯2  = √(σ₁²/n₁ + σ₂²/n₂ )

So as you can see, we used the square root to simplify and now we require the variance of each sample (σ²):

σ₁² = (14)² = 196

σ₂² = (15)² = 225

Now we can proceed to calculate the standard error of the distribution of differences in sample means:

σx¯1 - σx¯2  = √(196/100 + 225/90) =  2.11

This gives an estimate about how far is the difference between the sample means from the actual difference between the populations means.
