Hi
If u haven't given the pic it would be easy.
Thanks.

For uniform, the mean is:
<span>x¯ = (<span>590.0+590.9) 2</span></span>
The variance is:<span>
σ = sqrt [ (<span><span>n2−1) /</span>12 ]
</span></span><span>
Where n=10.
The answer would be 590.45
I hope my answer has come to your help. Have a nice day ahead and may God bless you always!</span>
Answer:
25 + 15n ≥ 150
Step-by-step explanation:
The term at least mean the amount saved is greater than or equal to 150
Let the number of weeks he intends to save be n
Amount saved after n weeks without the plan is:
15n
Add plan amount
= 25 + 15n
Add inequality
25 + 15n ≥ 150
Answer:
57 dollars and 14 or 15 cents
Step-by-step explanation:
400 divided by 7
Average rate of change is just the slope between the 2 points
we can do this the long way or the smart way
long way, find the 2 points and find the slope between them
when x=-5, f(-5)=-2(-5)+1=10+1=11
when x=1, f(1)=-2(1)+1=-2+1=-1
so the points are (-5,11) and (1,-1)
the slope between them is (-1-11)/(1-(-5))=(-12)/(1+5)=-12/6=-2
the answer is B, -2
smart way
recognize that that is a linear equation and the slope between any 2 points will be the m in y=mx+b
f(x)=-2x+1
the slope is -2
the average rate of change is -2
answer is B. -2
