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)
Answers
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.

Triangle KLM is isosceles with sides ML=240mm and MK=74mm calculate the size of angle MKL
Answers
Answer:
∠MKL = 81.13°
Step-by-step explanation:
240 mm has to be the equal legs because two 74 mm legs wouldn't work with a 240 mm base leg.
Drop a line from m to be perpendicular to LK.
This divides LK into two 37 mm segments.
cos ∠MKL = 37/240
cos ∠MKL = 0.1542
∠MKL = 81.13°

what line would be parallel to 8x-2y=7 with a point of 12,1
Answers
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]

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.
Answers
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
