A spherical tank has a capacity of 400 gallons. using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (to the nearest hundredth of a foot).
Final answer:
To find the radius of a spherical tank with a capacity of 400 gallons, calculate the volume and use the formula for the volume of a sphere.
Explanation:
A spherical tank has a capacity of 400 gallons, which is approximately 533.47 ft³ (400 gallons x 0.1337 ft³/gallon).
To find the radius, use the formula for the volume of a sphere: V = (4/3)πr³. Set this equal to the volume and solve for the radius.
Substitute the volume (533.47 ft³) into the formula, solve for r, and you will find that the radius is approximately 4.88 feet.
Find an equation of the vertical line that passes through (x, y) = (14, 15).
Final answer:
The equation of the vertical line passing through the point (14, 15) is x = 14.
Explanation:
To find an equation of a vertical line that passes through the point (14, 15), we need to understand that a vertical line has an undefined slope and therefore cannot be represented by the slope-intercept form of a line, y = mx + b. Instead, vertical lines are represented by equations where x is equal to a constant value since every point on the vertical line will share the same x-coordinate. Thus, the equation of the vertical line passing through (x, y) = (14, 15) is simply x = 14.

Y=x3, vertically stretch by a factor of 4. How would the final equation look like?
Vertically stretching the equation[tex]Y=x^3[/tex] by a factor of 4 results in the equation [tex]Y=4x^3[/tex]. This means that the value of the function increases four times for every x. Visually, the stretched function appears steeper along the y-axis.
Explanation:The equation represents[tex]Y=x^3[/tex] a cubic function. When you vertically stretch a function by a factor of 4, this means you multiply the output (Y-values) of the function by 4. Therefore, to vertically stretch Y=x3 by a factor of 4, you will multiply the entire function by 4. The final equation would look like [tex]Y=4x^3[/tex]
To clarify, the 'stretch' implies that for each x, the value of the function increases four times. This change can is noticeable graphically as the function will look 'steeper' or 'more stretched out' along the y-axis.

What is 7% of $20.00?
$1.40
Right on edge
Step-by-step explanation:
7 percent of the number 20.00 is 1.4.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Given that, 7% of 20.00
A percentage is a number or ratio that can be expressed as a fraction of 100.
Let x be the 7% of 20.00.
Here, 7% of 20.00 =x
7/100 ×20.00 =x (word "of" means multiplication)
0.07×20.00 =x
x=1.4
Therefore, 7 percent of the number 20.00 is 1.4.

Describe all solutions to ax = 0 in parametric vector form, where a is row equivalent to the given matrix.
Final answer:
The solutions to ax = 0 are all vectors in the null space of the matrix a. These solutions can be expressed as a parametric vector form, which may involve free variables if the matrix a has any. The general solution is a linear combination of the basis vectors for this null space.
Explanation:
The question is asking to describe all solutions to the equation ax = 0 in parametric vector form, given that a is row equivalent to a certain matrix. This matrix is understood to allow a decomposition of a vector into its perpendicular components. Such a matrix transformation typically reduces to finding the null space of the matrix.
To find the solution to ax = 0, we understand that any vector x that satisfies this equation is in the null space of a. The null vector is the most trivial solution, where all components of the vector are zero. But if there are free variables involved, the solutions may form a subspace spanned by these free variables. The general solution can then be expressed as a linear combination of these basis vectors that span the null space of a.
For instance, if our matrix a has one free variable, the parametric vector form of the solution might be t[1,0,0] if the first column of a is the pivot column and the rest are free columns. Here, t would be any scalar, representing a line through the origin in the direction of the vector [1,0,0] in three-dimensional space.

Find the equation of the circle in standard form for the given center (h,k) and radius r: (h,k)=(0,0), r=9
Answer: [tex]x^2+y^2=81[/tex]
Step-by-step explanation:
The equation of circle ( in general form ) is given by :_
[tex](x-h)^2+(y-k)^2=r^2[/tex]
, where r= radius of the circle .
(h,k) = center of the circle .
Given : Center = (h,k)= (0,0)
Radius = r = 9 units

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F.
F = 9 over 5C + 32
Which of the following formulas correctly solves for C?
C = 5F - 32 over 9
C = 5 F over 9 - 32
C = 9 over 5(F – 32)
C = 5 over 9(F – 32)
Answer:
C = 5 over 9(F – 32)
Step-by-step explanation:
The formula is [tex]F=(\frac{9}{5}C)+32[/tex]
We can do some algebra to solve for C (note the steps below):
[tex]F=(\frac{9}{5}C)+32\\F=(\frac{9C}{5})+32\\F-32=\frac{9}{5}C\\C=\frac{F-32}{\frac{9}{5}}\\C=\frac{5}{9}(F-32)[/tex]
Last answer choice is right.

The quotient of -18 and the sum of -2 and d
The quotient of -18 and the sum of -2 and d can be represented mathematically as -18 ÷ (d - 2), where we subtract 2 from d and then divide -18 by that result.
Explanation:The quotient of -18 and the sum of -2 and d refers to dividing -18 by the result of adding -2 to d (which we can represent as d - 2 because adding a negative number is equivalent to subtracting). Mathematically, we can express this as -18 ÷ (d - 2).
To perform this operation, we first need to know the value of d. Once we have that, we subtract 2 from it, and then divide -18 by that result.
For example, if d was 4, we would perform the operation as follows: 4 - 2 gives us 2, then -18 ÷ 2 gives us -9. So, the quotient of -18 and the sum of -2 and 4 (d being 4) is -9.

What is the difference between independent and conditional probability? Which one requires the use of the Addition Rule?Explain.
Answer:
In probability, independent events are those that if one event occurs, it does not change the probability of the other event.
Whereas conditional probability is defined as the probability of one event occurring with some relationship to one or more other events.
The addition rule is used for both the independent and conditional probabilities.
For independent event the probability is shown as :

Which of the following is true of an outlier?
An outlier is a false data point.
An outlier does not affect measures of central tendency.
An outlier is not near the main cluster of data.
An outlier is always the highest or lowest value in a data set.
An outlier is a data point that is significantly different from the other data points in a set. It may or may not affect measures of central tendency. Outliers are not always the highest or lowest values in a data set.
Explanation:An outlier is a data point that is significantly different from the other data points in a set. It can be either higher or lower than the other values.
Outliers may be errors or abnormal data, or they may provide valuable insights into the population under study.
An outlier does not necessarily mean that it is a false data point. It needs to be examined closely to determine if it should be included in the analysis or not.
An outlier may or may not affect measures of central tendency, such as the mean, median, and mode.
It depends on the specific data set and the impact of the outlier on these measures. It is not always the highest or lowest value in a data set, as it can be any data point that deviates significantly from the rest.
