Here's my previous one if you wanna see it though:
Answer:
A = 1280 in²
Step-by-step explanation:
We know that the volume of a cube is A = a³, where a is the length of one of the edges.
So, to find a:
a³ = 4096
a = ∛4096
a = 16 in
Now, we need to find the surface area of the square on the cube, where:
A = 6a², because we are making a box (that is empty inside).
However, we need to change the formula to:
A = 5a², because the problem says that there is no top (so there are only 5 squares)
A = 5(16)²
A = 1280 in²

The students measured length during a science experiment,they got 12 cm.But the actual measurement was 14.25cm.what was the percent error?
Answer:
Percent error = 15.79%
Step-by-step explanation:
Given the following data;
Experimental value = 12cm
Actual value = 14.25cm
To find the percentage error;
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - actual \; value}{ actual \;value} *100[/tex]
Substituting into the equation, we have;
[tex] Percent \; error = \frac {12 - 14.25}{14.25} *100[/tex]
[tex] Percent \; error = \frac {2.25}{14.25} *100[/tex]
[tex] Percent \; error = 0.1579 *100[/tex]
Percent error = 15.79%

Centerpieces are normally distributed with mean of 30 ounces and standard deviation of 2 ounces. The weights of the shipping boxes are normally distributed with mean of 12 ounces and standard deviation of 1 ounce. Suppose that centerpieces are chosen at random and packed into randomly chosen shipping boxes.If a package exceeds 45 ounces, an additional charge is incurred. What is the proportion of packages will incur such a charge
Answer:
0.0901 = 9.01% of packages will incur such a charge
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Sum of normal variables:
When we add normal variables, the mean will be the sum of the means, while the standard deviation is the square root of the sum of the variances.
Centerpieces are normally distributed with mean of 30 ounces and standard deviation of 2 ounces.
This means that [tex]\mu_C = 30, \sigma_C = 2[/tex]
The weights of the shipping boxes are normally distributed with mean of 12 ounces and standard deviation of 1 ounce.
This means that [tex]\mu_S = 12, \sigma_S = 1[/tex]
Suppose that centerpieces are chosen at random and packed into randomly chosen shipping boxes.
The shipment is given by the centerpice plus the shipping box. So the mean and the standard deviation of the weight are given by:
[tex]\mu = \mu_C + \mu_S = 30 + 12 = 42[/tex]
[tex]\sigma = \sqrt{\sigma_C^2 + \sigma_S^2} = \sqrt{2^2 + 1^2} = \sqrt{5} = 2.236[/tex]
If a package exceeds 45 ounces, an additional charge is incurred. What is the proportion of packages will incur such a charge
This proportion is 1 subtracted by the pvalue of Z when X = 45. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{45 - 42}{2.236}[/tex]
[tex]Z = 1.34[/tex]
[tex]Z = 1.34[/tex] has a pvalue of 0.9099
1 - 0.9099 = 0.0901
0.0901 = 9.01% of packages will incur such a charge
Find the difference.

Robert gets a job with a starting salary of $35,000. He is promised a $2500 raise each
subsequent year. Which of the following numbers represents his salary during his 7th
year of employment?
A. $45,000
B. $47,500
C. $50,000
D. $52,500
Step-by-step explanation:
starting salary = $35,000
raise in 1 year = $2500
raise in 7 year = $17,500
salary on 7th year = $35,000 + $17,500
= $52,500

Answer:
[tex]-\frac{3}{2}[/tex] < x or x > 4
Step-by-step explanation:
Convert the inequality to an equation.
2x² - 5x = 12
2x² - 5x - 12 = 0
Factor by grouping.
(2x + 3)(x - 4) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
2x + 3 = 0
x - 4 = 0
Solve for x.
x = -3/2
x = 4
Use each root to create test intervals.
The solution consists of all of the true intervals.
[tex]-\frac{3}{2}[/tex] < x or x > 4
good luck, i hope this helps :)

Lisa is making ethernet cables for Mrs. Houston in the computer lab. The spool of wire that she is creating the cables from is 40ft long. She creates 5 equal cables and has 12ft remaining. What was the length of each cable? (HOW DID YOU GET YOUR ANSWER PLEASE SHOW ME YOUR WORK!!)
A. 16.6%
B. 50%
C. 20%
D. 5.6FT
E. $29.40
F. $30.40
G. 6.3FT
H. 25%
Answer:
D. 5.6 ft
Step-by-step explanation:
40 ft - 12 ft = 28 ft (You subtract the leftover wire(12 ft) from the total amount(40 ft) so you can see how much wire was used to make the 5 cables. There was 28 ft of wire in total used to create the 5 cables.) 28 ÷ 5 = 5.6 ft (You divide 28 by 5 so that you can see how much wire was used for each cable.)Final Answer: The length of each cable was 5.6 ft or just 5.6 ft.Solve

Lillian wants to give 1/3 of a pizza to each of six girls at her party
Answer:
[tex]Fraction = \frac{1}{18}[/tex]
Step-by-step explanation:
Given
[tex]Pizza = \frac{1}{3}[/tex]
[tex]Girls = 6[/tex]
Required [Missing Information]
Determine the fraction each girl gets
To do this, we simply divide the pizza by the number of girls i.e.
[tex]Fraction = \frac{Pizza}{Girls}[/tex]
[tex]Fraction = \frac{1}{3} / 6[/tex]
Change / to *
[tex]Fraction = \frac{1}{3} *\frac{1}{6}[/tex]
[tex]Fraction = \frac{1}{18}[/tex]
Hence, each girl gets 1/18
A construction worker drops a hammer while building the Grand Canyon skywalk 4,000ft above the Colorado River. Use the formula t=h‾√4 to find how many seconds it takes for the hammer to reach the river. Round your answer to the nearest tenth of a second.
Answer:
The hammer reaches the river after 15.8 seconds.
Step-by-step explanation:
The formula to find for how long it takes for the hammer to reach the ground is given by:
[tex]t = \frac{\sqrt{h}}{4}[/tex]
In which h is the initial height.
A construction worker drops a hammer while building the Grand Canyon skywalk 4,000ft above the Colorado River.
This means that [tex]h = 4000[/tex].
So
[tex]t = \frac{\sqrt{4000}}{4}[/tex]
[tex]t^2 = \frac{4000}{16}[/tex]
[tex]t^2 = 250[/tex]
[tex]t = \sqrt{250}[/tex]
[tex]t = 15.8[/tex]
The hammer reaches the river after 15.8 seconds.
A coin will be tossed three times, and each toss will be recorded as heads (H) or tails (7). Give the sample space describing all possible outcomes. Then give all of the outcomes for the event that the second toss is heads. Use the format HTH to mean that the first toss is heads, the second is tails, and the third is heads. If there is more than one element in the set, separate them with commas. Sample space: Event that the second toss is heads: 0 Х ?

Which values are solutions to the inequality square root of x is less than 8? A. 55 B. 8 C. -8 D. 4 E. 65 F. -64
9514 1404 393
Answer:
A. 55
B. 8
Step-by-step explanation:
We want ...
√x < 8
x < 8² . . . . . square both sides
x < 64
In order for the inequality to make any sense, we must also have ...
0 ≤ x
So, the solution space is ...
0 ≤ x < 64
Only answer choices A (55) and B (8) are in that range.
