Possibly b but i don’t know
Answer:
False
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% confidence interval for the mean number of oranges eaten per week per person is 0.8 to 2.6.
This means that we are 95% sure that the true population means for the number of oranges eaten per week per person is 0.8 to 2.6, not that 95% of all people eat between 0.8 and 2.6 oranges per week. So the answer is False.
Answer:
c. Use a compass to swing an arc on either side of the segment for each endpoint.
Step-by-step explanation:
The steps to constructing a perpendicular bisector are illustrated in the attachment.
Steps 2 and 3 are described by answer choice C.
__
<em>Other choices</em>
(a) In order to get the arcs to intersect each other, their radius must be <em>more than</em> one half of the segment length.
(b) At no point in the construction are concentric circles involved.
(c) A ruler is not used in any <em>construction</em>. Only a straightedge with no markings will be used for construction.
Answer:
y = 11x -2
Step-by-step explanation:
The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.
In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).
The formula is now 2π4h + 2π4^2.
Next, plug in the height, 8 for h.
Now we have 2π4(8) + 2π4^2, which is approximately 301.59.
The surface area is 301.59. (Unit of measure was not specified)
