An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,
V ∝ h(r²)
Also, k is the constant of proportionality, therefore, the equation now can be written as,
V = k×h×r²
Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

A study was conducted to investigate whether the mean price of a dozen eggs was different for two different grocery stores, Store A and Store B, in a large city. A carton of one dozen eggs from each store was randomly selected for each of 35 weeks, for a total sample size of 35 cartons from each store. The mean price of the 35 cartons was recorded for each store. The difference in the mean carton price for the stores will be calculated.
Which of the following is the appropriate test for the study?
A one-sample z -test for a population proportion
A one-sample t -test for a sample mean
A matched-pairs t -test for a mean difference
A two-sample t-test for a difference between population means
A two-sample z-test for a difference between population proportions
Answer:
A two-sample t-test for a difference between population means
Step-by-step explanation:
Answer:
D) A two-sample t -test for a difference between population means

Step-by-step explanation:
in the parallelogram below z=?
Answer:
z = 20
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary so
124 + 2z + 16 = 180
2z = 40
z = 20
The value of z in the given diagram is 20°.
What is a parallelogram?A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.
As per the given data:
Two adjacent angles of a parallelogram are given in the diagram.
To find the value of z:
The sum of any two adjacent sides of a parallelogram is equal to 180°.
∴ 2z + 16° + 124° = 180°
= 2z = 180° - 140°
= 2z = 40°
z = 20°
Hence, the value of z in the given diagram is 20°.

[tex]\frac{x}{20}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{4}[/tex] - [tex]\frac{x}{5}[/tex]
The LCM of 4 and 5 is 20
= [tex]\frac{5x-4x}{20}[/tex]
= [tex]\frac{x}{20}[/tex]
A long-distance delivery truck averages 8 miles per gallon when the truck is full. The
miles per gallon improves by 20% when the truck is empty. If the truck travels 160 miles
full to deliver its goods, and then travels back 160 miles empty, approximately how many
gallons will the truck use in all?
The gas used by truck is 36.66 mpg.
What is linear equation?When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.
One-variable linear equations and two-variable linear equations exist.
Given
A long-distance delivery truck averages 8 miles per gallon when the truck is full.
The miles per gallon improve by 20% when the truck is empty.
The distance delivery truck averages 8 miles per gallon when full, and the amount of gasoline used (g) is expressed in terms of the number of miles driven ([tex]m_{f}[/tex]).
When the truck is full, the amount of gasoline is shown as,
[tex]m_{f}[/tex] = d/8
given distance is 160 miles
[tex]m_{f}[/tex] = 160/8 = 20 mpg
Then,
The miles per gallon improve by 20% when the truck is empty.
The number of miles driven when empty is represented as,
[tex]m_{e}[/tex] = d/(8 + 1.6)
[tex]m_{e}[/tex] = d/9.6
[tex]m_{e}[/tex] = 160/9.6
[tex]m_{e}[/tex] = 16.66 mpg
total gasoline required = [tex]m_{e}[/tex] + [tex]m_{f}[/tex] = 20 + 16.66 = 36.66 mpg
Hence the total gas used is 36.66 mpg.
