A carpenter worked 10 weeks on a particular job, 51/2 days per week and 7 3/4 hours per day. How many hours did the carpenter work on the job?
Answers
Answer:
= 426 1/4 hr.
Step-by-step explanation:
5 1/2 = 5.5 Days in a week
7 3/4 = 7.75 hr. Per Day
Total hours in a week = 5.5 × 7.75 = 42.625 hr in a week
In 10 weeks = 42.625 × 10 = 426.25 hr.

There are 23 animals in the barn. Some are chickens some are goats. There are 80 legs in all. How many of each animal is there?
Answers
There are 17 goats and 6 chickens
Explaining: (1) C + G = 23
As for legs:
(2) 2C + 4G = 80 (each C has 2 legs and each G has 4 legs)
Solving equation (1): C = 23 - G
Substituting in equation (2)
2(23 - G) + 4G = 80
2G = 34
G = 17
C = 6
Sara has 2 pounds of chicken. She uses 5 ounces of chicken while cooking. How can you determine the mass of chicken that she has left?
Answers
Answer: 27 ounces of chicken.
Step-by-step explanation:
Sara has 2 pounds of chicken.
She uses 5 ounces of chicken.
So now, she has:
(2 pounds - 5 ounces ) of chicken.
To perform this subtraction, we first need to write bot quantities in the same units.
First, we know that:
1 pound = 16 ounces.
Then we can rewrite 2 pounds, this is equal to 2 times 16 ounces.
2 pounds = 2*16 ounces = 32 ounces.
Then initially she has 32 ounces, and she uses 5 ounces.
Now she has:
(32 ounces - 5 ounces) = 27 ounces of chicken
You have a loan for $200,000 at 8.5% annual simple interest.what is your monthly interest payment
Answers
Answer:
~1467
Step-by-step explanation:
$200,000 x 8.5% or .085 = $17,000 Annualy
$17,000 / 12 Months out of the year = $1466 2/3 Monthly Payments
Answer is $1467 Rounded
The monthly interest payment is $1,467.
Given that,
The loan amount is $200,000.The rate of interest is 8.5%.We need to find out the monthly interest payment.Based on the above information, the calculation is as follows:
[tex]= (\$200,000 \times 8.5\%) \div 12[/tex]
= $1,467

You choose at random 3 of those over 21 and separately choose at random 2 of those under 21 to interview about attitudes toward alcohol. You have given every student at the party the same chance to be interviewed: what is that chance
Answers
Answer:
10%
Step-by-step explanation:
According to the scenario, given data are as follows:
Students over age 21 = 30
Students under age 21 = 20
Choose student over age 21 = 3
Choose student under age 21 = 2
So, we can calculate chances by using following method,
Chances of student over age 21 = Number of choose student ÷ Total students
= 3 ÷ 30 = 0.10 = 10%
Similarly, Chances of student under age 21 = Number of choose student ÷ Total students
= 2 ÷ 20 = 0.10 = 10%
Hence, in both condition, chances are 10%.
What is the solution to this system of equations?

Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}\frac{2}{3}x+y=6\\ -\frac{2}{3}x-y=2\end{bmatrix}[/tex]
Adding both equations
[tex]-\frac{2}{3}x-y=2[/tex]

0 = 8 is FALSE!
Therefore, the system of equations has no solution.
Thus,

Step-by-step explanation:

The length of a rectangular table is 3 times its width. If the total perimeter of the table is 36 meters. What is the length and the width of the table?
Answers
Answer:
Length = 13.5 m
Width = 4.5 m.
Step-by-step explanation:
Use an equation in x, where x = width of the table.
Length = 3x, so:
2*3x + 2x = 36
6x + 2x = 36
8x = 36
x = 36/8 = 4.5 metres.
So the length = 3*4.5 = 13.5 and width = 4.5 m.
Length = 13.5 m
Width = 4.5 m.
What is the perimeter?A closed route that covers, encircles, or outlines a one-dimensional length or a two-dimensional form is called a perimeter.
Given, The length of a rectangular table is 3 times its width. If the total perimeter of the table is 36 meters.
Use an equation in B, where B = width of the table.
Length = 3B,
2*3B + 2B = 36
6B + 2B = 36
8B = 36
B = 36/8 = 4.5 meters.
So the length = 3*4.5 = 13.5 and width = 4.5 m.
Therefore, the length and the width of the given rectangle are 4.5 and 13.5 respectively.

The cost to produce a batch of granola bars is approximately Normally distributed with a mean of $7.19 and a standard deviation of $0.86. If a random sample of 12 batches of granola bars is selected, what is the probability that the mean cost will be more than $7.00?
0.2220
0.2339
0.7653
0.7780
Answers
Answer:
0.7780
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use 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.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
We have that [tex]\mu = 7.19, \sigma = 0.86[/tex]
Sample of 12:
[tex]n = 12, s = \frac{0.86}{\sqrt{12}} = 0.2483[/tex]
What is the probability that the mean cost will be more than $7.00?
This is 1 subtracted by the pvalue of Z when X = 7. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{7 - 7.19}{0.2483}[/tex]
[tex]Z = -0.765[/tex]
[tex]Z = -0.765[/tex] has a pvalue of 0.222
1 - 0.222 = 0.778
So the answer is 0.7780
