The best estimate for the cost of the sewing project is between $30 and $40. Hence option 'a' is correct.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction.
It can be written as the form of [tex]p : q[/tex], which is equivalent to p / q.
Given that,
The sewing project also requires 3 1/4 yards of material selling for $3 per yard.
To calculate the cost of the sewing project:
Compute the cost of each type of material separately and then add them together.
For the first type of material:
We need [tex]6\dfrac{1}{8}[/tex] yards, which is equivalent to 6.125 yards.
The cost of this material would be,
6.125 x 4 = $24.50
For the second type of material:
We need [tex]3\dfrac{1}{4}[/tex] yards, which is equivalent to 3.25 yards.
The cost of this material would be,
3.25 x 3 = $9.75.
Now, add the costs of the two types of materials together:
$24.50 + $9.75 = $34.25.
Hence,
The cost of the project would be between $30 and $40,
Which is option a.

The art club at a community college is selling burgers at lunchtime as a fundraiser. The club spends $8 for condiments and supplies. The cost of the meat and bun for each burger is $0.65. Express the total cost, C, as a function of the number of burgersmade, x.
Answer:
C(x)=0.65x+8
Step-by-step explanation:
According to the information given, you can say that the total cost would be equal to the result of multiplying the cost of the meat and bun per burger for the number of burgers made plus the amount spent on condiments and supplies, which can be expressed as:
C(x)=0.65x+8, where:
C(x) is the total cost
x is the number of burgers made

Answer:
45
Step-by-step explanation:
If you write it out it will look like this, 2x+45+x=180
3x+45=180
3x+45=180
-45 -45
3x=135
/3 /3
x=45
Answer:
x=45
Step-by-step explanation:
Straight angles/lines are equal to 180 degrees. If you add the equations together to get 180 and simplify you'll find the answer. So, start out with the equation 2x+45+x=180.
1. Add like terms. 3x+45=180
2. Subtract 45 from both sides. 3x=135
3. Divide by 3 on both sides to get x by itself. x=45
4. Just to make sure, plug in 45 for x. 2(45)+45+45=180. Sure enough, it works!

You are in charge of monitoring the pressure of a compressed air tank in a processing plant. After repeating the pressure measurement a large number of times, you found that the pressure values have Gaussian distribution with a mean value of 69 psi and a standard deviation of 10 psi. If it is important that the pressure stays below 86 psi, what is the probability (in percent) that the pressure will exceed this value? (Provide your answer as a percentage using two decimal places. Do not include the % symbol in your answer)
Answer:
4.46% probability that the pressure will exceed this value.
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.
Gaussian distribution with a mean value of 69 psi and a standard deviation of 10 psi.
Gaussian distribution = normal.
This means that [tex]\mu = 69, \sigma = 10[/tex]
If it is important that the pressure stays below 86 psi, what is the probability (in percent) that the pressure will exceed this value?
As a proportion, this probability is 1 subtracted by the pvalue of Z when X = 86. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{86 - 69}{10}[/tex]
[tex]Z = 1.7[/tex]
[tex]Z = 1.7[/tex] has a pvalue of 0.9554
1 - 0.9554 = 0.0446
0.0446*100 = 4.46%
4.46% probability that the pressure will exceed this value.

2. (3 marks) A marketing company conducted a box office study and they found the following. The probability that a husband watches the movie Toy Story is 0.4 while the probability that a wife watches the movie is 0.5. The probability that a husband watches the movie, given that his wife does, is 0.7. (a) What is the probability that a married couple watches the movie
Answer:
0.35 = 35% probability that a married couple watches the movie
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
The probability that a husband watches the movie, given that his wife does, is 0.7.
This means that [tex]P(B|A) = 0.7[/tex]
The probability that a wife watches the movie is 0.5.
This means that [tex]P(A) = 0.5[/tex]
What is the probability that a married couple watches the movie?
Both, so:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
[tex]P(A \cap B) = P(B|A)*P(A) = 0.7*0.5 = 0.35[/tex]
0.35 = 35% probability that a married couple watches the movie
what line would be parallel to 8x-2y=7 with a point of 12,1
Answer:
[tex]y = 4x - 47[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
Parallel lines:
When two lines are parallel, they have the same slope.
8x-2y=7
Placing into the format, we have thtt:
[tex]2y = 8x - 7[/tex]
[tex]y = 4x - \frac{7}{2}[/tex]
Slope of 4.
This means that the desired line has the following equation:
[tex]y = 4x + b[/tex]
Point of (12,1)
This means that when [tex]x = 12, y = 1[/tex]
We use this to find b.
[tex]y = 4x + b[/tex]
[tex]1 = 48 + b[/tex]
[tex]b = -47[/tex]
So, the line has the equation:
[tex]y = 4x - 47[/tex]

-8, -14, -20,–26,
Answer:
-8, -14, -20, -26, -32, -38
Step-by-step explanation:
if we do this equation:
14 - 8 = 6
20 - 14 = 6
26 - 20 = 6 and you will do this until you get the answer you want.
so the arithmatic squence is -8, -14, -20, -26, -32, -38
