Step-by-step explanation:
The given points have coordinates; P=(5,4), Q=(7,3), R=(8,6), and S=(4,1).
The correct answer is C
The magnitude is given by:
The correct answer is B
By Using the Empirical formula we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
<h3>What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches?</h3>
According to the empirical rule :
(1) 68% of the measures should come within 1 standard deviation of the mean.
(2 95% of the measures should come within 2 standard deviations of the mean.
(3) 99.7% of the measures should come within 3 standard deviations of the mean.
So we can see in this problem
The mean is 7 inches.
The standard deviation is 1.2 inches.
4.6 = 7 - 2(1.2)
9.4 = 7 + 2(1.2)
The measures are within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
Thus by using the Empirical Rule we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

Answer:
212.6 units²
Step-by-step explanation:
Area of the figure = area of rectangle + area of semicircle
✔️Area of rectangle = length * width
Length = 13
Width = 6*2 = 12
Area of rectangle = 156 units²
✔️Area of semicircle = ½(πr²)
r = 6
Area of semicircle = ½(π*6²) = ½(π*36) = 56.55 units²
✔️Area of the figure = 156 + 56.55 = 212.55 ≈ 212.6 units² (to nearest tenth)
