Yep :) You're right!

The total probability of anything is always 100%, obviously.

If there are 4 choices, and you're equally likely to select either one, you can do 100% / 4 choices = 25%.

One of them have to be correct, so 1 of the 4 are bound to be right. 1/4 is also the same as 25%, hence you're correct! :)

Which is the best estimate for the average rate of change for the quadratic function graph on the interval 0
snow_lady [41]

Answer:

Step-by-step explanation:

0 is not an interval, it is just the origin

hard to make an estimate without knowing the limits.

average rate of change will be Δy / Δx or (y - y₀) / (x - x₀)

as (0, 0) is the origin and appears to be on the plot line, the average rate of change will be y/x for any other point on the curve relative to the origin.

EDIT

for interval 0 ≤ x ≤ 8

at x = 8 y appears to be -24

average change is -24 / 8 = -3

Construct an interval estimate for the given parameter using the given sample statistic and margin of error. For μ1-μ2, using x¯
maks197457 [2]

Answer: CI = (0, 8)

Step-by-step explanation: Confidence interval for difference between mean is given below as

Lower limit

= (x1 - x2) + margin of error

Upper limit

= (x1 - x2) - margin of error

where x1 - x2 = 8 and margin of error = 8

For lower limit,

= 8 - 8 = 0

For upper limit

= 8 + 8 = 16

Hence CI = (0, 8)

Choose the point slope form of the equation below that represents the line that passes through the point (6,-3) and has a slope
yulyashka [42]
The equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(6,-3)
(x1,y1)
and slope is 1/2
y-(-3)=1/2(x-6)
y+3=1/2(x-6)
that is point slope
