Volume of the cylinder = πr²h = π(1)² (21) = 21π cm³
Volume of the cone = 1/3 π r² h
21π = 1/3 π (r)² (7)
r³ = 21π ÷ (7/3 π)
r² = 9
r = 3
Answer : Radius = 3
Answer:
C=−Ax−By
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
A) mean = 1.2
B) median
C) The measures of center use data points to approximate a middle value or average of a given data set
Step-by-step explanation:
The “balance” process was developed to provide another way in which the mean characterizes the “center” of a distribution.
The mean is the balance point of the data set when the data are shown as dots on a dot plot (or pennies on a ruler).
A) The balance point for the points 0.4, 1.4, and 1.8. Will be
(0.4 + 1.4 + 1.8)/3 = 3.6/3 = 1.2
B) The median is the measure of center that is indicated by the center of balance
The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.
C) A measure of central (measure of center tendency) is a value that describe a set of data by identifying the central position of the data set. The three measures of central tendency are the mean, median and mode.

Answer: 0.0668073
Step-by-step explanation:
Given : The number of miles each tire lasts before it completely wares out follows a normal distribution with mean μ = 50,000 miles and standard deviation σ = 8,000 miles.
Let x be the random variable that represents the number of miles each tire lasts.
z-score :
For x= 62,000
By using the standard z-value table , the probability for a randomly selected tire to last for at least 62,000 miles will be :_
Hence, the probability for a randomly selected tire to last for at least 62,000 miles = 0.0668073
