Drag the orange points on the cylinder and the cone to change their radii and heights. (Make sure the Freeze height checkboxes are not checked.) Set equal radii and heights for the cylinder and the cone, and note their respective volumes. Record the volumes for a few sets of heights and radii, and calculate the ratio of the volumes in each case. Remember, make sure the height and radius of the cone and the cylinder are the same in each pair. (You might see some discrepancies in the tool due to rounding of decimals.) Round your calculations for ratio to the hundredths place. The first one has been done for you.

answer: the value of x is 7cm

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

care to share were the trapezoid shown is ?

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
