Find the side length of a cube with a volume of 141 f3 If necessary, round your answer to the nearest tenth.
The side length of the cube is 5.6 feet (rounded to the nearest tenth).
We can calculate the side length of a cube with a volume of 141 cubic feet using the formula for cube volume , which is \(V = s^3\), where V is the volume and s is the side length.
We can calculate s by taking the cube root of both sides of the equation:
\(s = (V)^{(1/3)\)
Substituting V = 141, we get:
\(s = (141)^{(1/3)\)
By using a calculator to evaluate this expression, we may determine:
s ≈ 5.6
As a result, the cube's side length is roughly 5.6 feet (rounded to the closest tenth). This indicates that if we increase the side length by three, it will become longer. (\(s^3\)), we will get the volume of the cube, which is 141 cubic feet.

Geometric figure: Straight Line
Slope = 120.000/2.000 = 60.000
x-intercept = 346/-60 = 173/-30 = -5.76667
y-intercept = 346/1 = 346.00000

Equation of a Straight Line
1.1 Solve y-60x-346 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-60x-346 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 346/1 so this line "cuts" the y axis at y=346.00000
y-intercept = 346/1 = 346.00000
Calculate the X-Intercept :
When y = 0 the value of x is 173/-30 Our line therefore "cuts" the x axis at x=-5.76667
x-intercept = 346/-60 = 173/-30 = -5.76667
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 346.000 and for x=2.000, the value of y is 466.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 466.000 - 346.000 = 120.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 120.000/2.000 = 60.000
Geometric figure: Straight Line
Slope = 120.000/2.000 = 60.000
x-intercept = 346/-60 = 173/-30 = -5.76667
y-intercept = 346/1 = 346.00000
allprime numbers are not divisible by two true or false
Answer:
False
Step-by-step explanation:
This is false although most prime numbers are not divisible two, but there is one exception to this... the number 2! The number 2 is prime and is divisible by 2. All other prime numbers cannot be divisible by 2 otherwise they would not be prime as prime numbers are only divisible by 1 and the number it self (this excludes 1).
Scores on the GRE (graduate record examination) are normally distributed with a mean of 553 and a standard deviation of 112. Use the 68-95-99.7 rule to find

The percentages of people taking the test who scores between 421 and 645 is__%
The percentages of people taking the test who scores between 421 and 645 is: 68 %
How to use the empirical rule of statistics?The empirical rule, also referred to as the three-sigma rule or the 68-95-99.7 rule, is defined as a statistical rule which states that almost all observed data for a normal distribution will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).
We are given:
Sample mean: x' = 553
standard deviation; s = 112
Thus:
x' - ns = 421
x' + ns = 645
Where n is the number of standard deviations from the mean. Thus:
553 - 112s = 421
112s = 553 - 421
112s = 132
s = 132/112
s ≈ 1
So 1 standard deviation from the means indicates a percentage of 68%

A dairy needs 258 gallons of milk containing 7% butterfat how many gallons each of milk containing 8% butterfat and milk containing 2% butterfat must be used to obtain the desired 258 gallons
Let's assume x gallons of milk containing 8% butterfat and y gallons of milk containing 2% butterfat are used.
The total amount of milk is x + y gallons, and we want it to be equal to 258 gallons.
To determine the amount of butterfat in the mixture, we can multiply the volume of each type of milk by its respective butterfat percentage and sum them up.
For milk containing 8% butterfat, the amount of butterfat is 0.08x (8% is equivalent to 0.08 as a decimal).
For milk containing 2% butterfat, the amount of butterfat is 0.02y (2% is equivalent to 0.02 as a decimal).
Since we want the final mixture to contain 7% butterfat, we can set up the following equation:
0.08x + 0.02y = 0.07(258)
Simplifying the equation, we have:
0.08x + 0.02y = 18.06
To solve for x and y, we need another equation. Since the total amount of milk is x + y = 258, we can rearrange it to y = 258 - x.
Substituting this value into the equation above, we get:
0.08x + 0.02(258 - x) = 18.06
Solving this equation will give us the values of x and y, which represent the gallons of milk containing 8% butterfat and 2% butterfat, respectively, needed to obtain the desired 258 gallons.

Step-by-step explanation:
We have the following functions
\(q(x) = x^2+4\\\\and\\\\r(x) = \sqrt{x+5}\\\\\)
1. To find
\((r \;\circ \;q)(4) = r(\;q(4)\;)\)
First find
\(q(4) = 4^2 + 4 = 16 + 4 = 20\)
Substitute this value for x in r(x)
\(r(20) = \sqrt{20 + 5} = \sqrt{25} = 5\)
So
\(\bold{(r \;\circ \;q)(4) = 5}\)
2. To find
\((q \;\circ\;r)(4) = q(\;r(4)\;)\)
First find
\(r(4) = \sqrt{4 + 5} = \sqrt{9} = 3\\\\\)
Substitute this value for x in q(x)
\(q(3) = 3^2 + 4 = 9 + 4 = 13\\\\\bold{(q \;\circ\;r)(4) = 13}\)

Question 1 0.1 pts The initial cost of a pickup truck is $12,659 and will have a salvage value of $3,580 after five years. Maintenance is estimated to be a uniform gradient amount of $135 per year, with zero dollar for first year maintenance. The operation cost is estimated to be $0.2 per mile for 344 miles per month. If the interest rate is 12%, what is the annual equivalent cost (AEC) for the truck? Enter your answer as follow: 123456
The annual equivalent cost (AEC) for the pickup truck is $4,308. We found the equivalent uniform annual cost (EUAC) first.
To calculate the AEC, we need to first find the equivalent uniform annual cost (EUAC) which includes both the initial cost and the present value of the maintenance and operation costs.
Find the present value of maintenance costs over five years using the gradient formula:
PV maintenance = A * [(1+i)^n - (1+i- g)^n] / [i - g]where A = $135, i = 12%, g = 0, n = 5
PV maintenance = $501.21
Find the present value of operating costs over five years using the present value formula:
PV operation = C * [1 - (1 + i)^-n] / iwhere C = $0.2/mile * 344 miles/month * 12 months/year = $827.52/year, i = 12%, n = 5
PV operation = $3,322.08
Find the EUAC using the formula:
EUAC = (initial cost + PV maintenance + PV operation) * A/Pwhere A/P = [(1+i)^n * i] / [(1+i)^n - 1]
EUAC = ($12,659 + $501.21 + $3,322.08) * 0.1464EUAC = $2,219.77Finally, convert the EUAC to AEC by adding the present value of the salvage value and multiplying by the interest rate:
AEC = (EUAC + PV salvage) * iwhere PV salvage = $3,580 / \((1+i)^5\)
AEC = ($2,219.77 + $2,267.03) * 0.12AEC = $4,308.Learn more about Cost and Estimate:

How Much would you have to invest today to receive $6,000 each year for 10 years at 9 percent?
You have to invest $31,579 today to get $6,000 each year for 10 years at 9 percent.
What is Simple Interest?Simple interest is defined as the interest obtained over the principal amount on a certain rate.
Given that,
Number of years, n = 10 years
Rate of interest, r = 9% = 0.09
Amount received each year = $6,000
Amount received in 10 years = $6,000 × 10 = $60,000
Final amount, A = $60,000
To find the principal amount that you invest today,
A = P (1 + rt)
60,000 = P(1 + (0.09 × 10))
60,000 = P (1.9)
P = 60,000 / 1.9
P = 31578.947 ≈ 31,579

The confidence interval (0.297, 0.503) represents the range of values within which the true difference in proportions between the two customer groups is likely to fall with 99% confidence. Since the interval does not include zero (0), we can conclude that there is a statistically significant difference between the proportions.
To further explain, the confidence interval was constructed using the sample proportions and the standard error. The sample proportion for the "big" customers who bank with other banks is 160/200 = 0.8, and for the "small" customers, it is 120/300 = 0.4. The standard error takes into account the sample sizes and proportions, and it measures the uncertainty in the estimation.
Since the confidence interval does not include zero, it indicates that the true difference in proportions is unlikely to be zero. In other words, there is strong evidence that the proportion of "big" bank customers who bank with more than one bank is higher than the proportion of "small" customers who do the same.
Therefore, based on the provided data and the confidence interval, we can conclude that there is convincing evidence of a difference in the proportion of "big" bank customers who bank with more than one bank compared to the "small" customers who bank with more than one bank.
