Answer: (92, 128)
Step-by-step explanation:
According to the Empirical rule,
If the population is normallly distributed, then 95% of the population lies within 2 standard deviations from the mean.
Given: Mean = 110
Standard deviation = 9
The interval of systolic blood pressures represent the middle 95% of males:
(110-2(9), 110+2(9))
= (110-18, 110+18)
= (92, 128)
Hence, the interval of systolic blood pressures that represent the middle 95 % of males = (92, 128)
Answer:
12 Weeks.
Step-by-step explanation:
2418 minus 1804 is 614.
614 divided by 55 is 11.1, and you can't have 11.1, so you round to 12.
So 12 is therefore your answer.
Answer:
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the gradient and c is the y-intercept.
Gradient
Substitute the value of the gradient into the equation:
To find the value of the y-intercept, substitute a pair of coordinates.
When x= -1, y= -8,
Thus the equation of the line is 
.
3t - 12 = 40
I'm pretty sure this is right
Answer:
a = -1, h = 2, k = 3
Step-by-step explanation:
(h,k) : (2,3)
f(x)=a|x-h|+k pass (0,1)
1 = a|0-2|+3 = 2a + 3
2a = -2
a = -1
