Answer:
x = 2 and y = 7
Step-by-step explanation:
The given equations are :
Squaring both sides of equation (2)
Put the value of y from equation (2)
Put the value of x in equation (2)
y-x = 5
y = 5+x
= 5+2
= 7
Hence, the solution of the given equations are (2,7).
First, let's simplify the inequality as much as we can:
-4x + 7 > 15
-4x > 8
Divide by -4:
x < -2
Answer:
The lengths from 32.1cm to 46.5cm covers 99.7% of this distribution.
Step-by-step explanation:
The 68-95-99.7 rule states that, for normally distributed measures:
68% of the values are within 1 standard deviation of the mean.
95% of the values are within 2 standard deviations of the mean.
99.7% of the values are within 3 standard deviations of the mean.
(a) What range of lengths covers almost all, 99.7%, of this distribution?
Those are those values within 3 standard deviations of the mean. So
From A to B, in which
The lengths from 32.1cm to 46.5cm covers 99.7% of this distribution.
