denis23 [38]

Answer:

The radius of the sphere, to the nearest cm:

r\approx 20 cm

Step-by-step explanation:

The surface area of a sphere is given by the formula

A = 4πr²

where r is the radius of the sphere.

Given

  • The surface area of sphere A = 5024 cm²

The radius of the sphere can be determined such as

A\:=\:4\pi r^2

r\:=\:\frac{1}{2}\sqrt{\frac{A}{\pi }}

Plug in Surface Area of sphere =  5024, π = 3.14 in the formula

\:r\:=\:\frac{1}{2}\sqrt{\frac{5024}{3.14}}\:\:

r\approx 20 cm

Therefore, the radius of the sphere, to the nearest cm:

r\approx 20 cm

The dot plot shows how many cats are owned by each person in a neighborhood:
REY [17]

If we plot the data on the graph, we can see that the data is skewed to the right (positive skew) and there is an outlier. In skewed data and presence of outlier, the median is most commonly used measure of central tendency. This is because a positive skew would result in a positive bias to the mean. Meaning that it would be a lot larger than the median and not really representing the actual central tendency. The median however is less affected by the skew and outliers.

Answer: Median, because the data are skewed and there is an outlier

Which of these intervals has an average rate of change that is less than 1/4
RideAnS [48]

Answer:

Interval [b,c] and interval [c,d]

Step-by-step explanation:

a(-5,0)

b(-1,2)

c(4,3)

d(11,4)

The average rate of change is the the total rise over the total run.

The Rise means the vertical increase and the Run means horizontal incease.

For interval [a,b]

rate of change is \dfrac{2-0}{-1-(-5)}=\dfrac{2}{4}=\dfrac{1}{2}

For [b,c]

\frac{3-2}{4-(-1)}=\frac{1}{5}

For [c,d]

\dfrac{4-3}{11-4}=\dfrac{1}{7}
