Answer:
Mean = ∑x + standard deviation = 429.21
Step-by-step explanation:
Mean lifespan = 71.45 years
Standard deviation = 12.35 years
Standard deviation= ∂ = x-µ / N
∂ = standard deviation
µ= mean
x = size of year
By using formula of standard deviation:
= 70 – 71.45 / 12.53
Approximately equal to 64.21
Mean = ∑x + standard deviation
= 365 + 64.21
= 429.21
<em>(4, -2)</em>
Step-by-step explanation:
For a reflection across the y-axis, you need to change the sign of the x to the opposite of what it was.
(x, y) to (-x, y)
If C has the coordinates of (-4, -2), to figure out the coordinates of C' after a reflection of the y-axis, we will change the sign of the x.
C' would be located at the coordinates (4, -2).
1350x + 450
Step-by-step explanation:
(5(3+8−2)(1))(10x(3)+(5)(2))
(5(3+8−2)(1))(10x(3))+(5(3+8−2)(1))((5)(2))
Answer:
mean =503.75
median=400
mode=400
range=691
Step-by-step explanation:
mean= 211+351+359+400+400+659+748+902=4030/8= 503.75
range= highest number -lowest number = 902-211=691
median= 400+400 =800/2= 400
