Answer:
i think 6 x 72 = calculator
Step-by-step explanation:
As the normal distribution is symmetric the mean is (36 +
42) / 2 = 39
p(X < 42) = 1 - 0.063 = 0.937
From tables Φ (1.53) = 0.9370
From this time:
42 is 1.53 standard deviations above the mean
42 = 39 + 1.53s
1.53s = 3
Standard deviation is = 1.96
Answer: <em>-5 5/8 i think :)</em>
Answer:
D, x = -2
Step-by-step explanation:
The slope of y = -2 is 0, because it is horizontal. The perpendicular slope of a horizontal slope is a vertical, which has x equaled to a number. The answer is D, x = -2, because its slope is undefined, or vertical. This makes it perpendicular to 0, or horizontal.
Answer:
Amount of grass needed (In square meter) = 34 meter²
Step-by-step explanation:
Divide given shape into rectangle and trapezium
Given:
Width of rectangle = 2 m
Length of rectangle = 5 m
Height of parallelogram = 9 - 5 = 4 m
Base of parallelogram = 10 m
Opposite site of parallelogram = 2 m
Find:
Amount of grass needed (In square meter)
Computation:
Amount of grass needed (In square meter) = Area of rectangle + Area of parallelogram
Amount of grass needed (In square meter) = (l x b) + (1/2)(sum of parallelogram)(height)
Amount of grass needed (In square meter) = (5 x 2) + (1/2)(2 + 10)(4)
Amount of grass needed (In square meter) = 10 + (1/2)(12)(4)
Amount of grass needed (In square meter) = 10 + 24
Amount of grass needed (In square meter) = 34 meter²
