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).

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.
A television news program asks its viewers to call in to give their opinions on an upcoming ballot question. What type of sampling method does this represent?
Answer:
This is an example of self selecting sampling
Step-by-step explanation:
This is an example of self selecting sampling because the news program is asking viewed to give their opinions. The viewers themselves have a choice of participating in the sample therefore is self selecting.

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
Triangle KLM is isosceles with sides ML=240mm and MK=74mm calculate the size of angle MKL
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°

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
