Area of a parallelogram:
BH x 1/2
In this case 7 and 6 are your base and the height is your half.
Answer:
I believe the answer is A: A = 6 * 7
Step-by-step explanation:
Ok, I may be wrong, but this is how I see the answer:
The formula for how to find the area of a parallelogram is A = b * h.
Base = 6 m
Height = 7 m
A = 6 * 7

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.

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!

The polynomial 10x3 + 35x2 − 4x − 14 is factored by grouping.
10x3 + 35x2 − 4x − 14
5x2(____) − 2(____)
What is the common factor that is missing from both sets of parentheses?
Answer:
The answer is "[tex]2x+7[/tex]".
Step-by-step explanation:
In this question, it can measure this using the following step if you'd like to find the missing element in both types of parentheses:
[tex]\to 10x^3 + 35x^2 - 4x - 14 \\\\\to (5x^2-2) (2x+7)\\\\\to 5x^2 (2x + 7) - 2 (2x + 7)\\[/tex]
So, the correct answer would be (2x + 7).

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

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]

What is the next term of the arithmetic sequence?
-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
