Answer:
Step-by-step explanation:
Given m ∠ Q P S = 4 7 ∘ m∠QPS=47 ∘ m, angle, Q, P, S, equals, 47, degrees m ∠ R P S = 3 x − 3 8 ∘ m∠RPS=3x−38 ∘ m, angle, R, P, S, equals, 3, x, minus, 38, degrees m ∠ Q P R = 7 x − 9 5 ∘ m∠QPR=7x−95 ∘
Sum of angles in a triangle = 180°
47° + 3 x − 3 8 ∘ + 7x - 95° = 180°
10x + 180° = 180°

The third one because it says 4 of 7 and the rest which is 3 eat a school meal
So the ratio is 4:3
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98
<h3>What is a sample size?</h3>
The sample size is a term used in market research for defining the number of subjects included in a sample size. By sample size, we understand a group of subjects that are selected from the general population and is considered a representative of the real population for that specific study.
Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.
For a population mean of 20.15 and a standard deviation of 3.7
68% are within μ ± σ/√n,
hence,
68% = 20.15 ± 3.7/√20 = (19.32, 20.98)
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98.

Length of the rectangle is 24.5 ft and width is 27.5 ft
Step-by-step explanation:
- Step 1: Let the length of the rectangle be x, then width = x - 3. Find dimensions when perimeter = 104 ft
Perimeter = 2(length + width)
⇒ 104 = 2(x + x-3)
⇒ 104 = 2(2x - 3)
⇒ 104 = 4x - 6
⇒ 4x = 110
∴ x = 110/4 = 27.5
⇒ x - 3 = 24.5
