Terms/CoefficientsStep-by-step explanation:
Step 1: Define
5(2x - 8) + 15 = -15
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 15 on both sides: 5(2x - 8) = -30[Division Property of Equality] Divide 5 on both sides: 2x - 8 = -6[Addition Property of Equality] Add 8 on both sides: 2x = 2[Division Property of Equality] Divide 2 on both sides: x = 1Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(2(1) - 8) + 15 = -15(Parenthesis) Multiply: 5(2 - 8) + 15 = -15(Parenthesis) Subtract: 5(-6) + 15 = -15Multiply: -30 + 15 = -15Add: -15 = -15Here we see that -15 does indeed equal -15.
∴ x = 1 is the solution to the equation.
Answer: x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
5(2x−8)+15=−15
Step 1: Simplify both sides of the equation.
5(2x−8)+15=−15
(5)(2x)+(5)(−8)+15=−15(Distribute)
10x+−40+15=−15
(10x)+(−40+15)=−15(Combine Like Terms)
10x+−25=−15
10x−25=−15
Step 2: Add 25 to both sides.
10x−25+25=−15+25
10x=10
Step 3: Divide both sides by 10.
10x/10=10/10

The volume inside a rectangular storage room is 2061 feet The room is 9 feet high find the area of the floor
Answers
Answer:
The area of the floor equals 229 square feet.
Step-by-step explanation:
The volume of a rectangular storage is given by the area of the floor multiplied by the height of the room. (It follows directly from the formula of a bar.) So the area of the floor is given by the volume of the rectangular storage divided by the height of the room. In symbols: [tex]V=Ah[/tex] gives [tex]h=\frac{V}{A}[/tex]. Substituting the given gives that [tex]h=\frac{2061}{9}=229[/tex] square feet, precisely what we were asked.
Answer:
The area of the floor is 229 ft.
A new version of the Medical College Admissions Test (MCAT) was introduced in spring 2015 and is intended to shift the focus from what applicants know to how well they can use what they know. One result of the change is that the scale on which the exam is graded was modified, with the total score of the four sections on the test ranging from 472 to 528. In spring 2015, the mean score was 500.0 with a standard deviation of 10.6.
Required:
What are the median and the first and third quartiles of the MCAT scores?
Answers
Answer:
The median of the MCAT scores was of 500.
The first quartile of MCAT scores was of 492.845.
The third quartile of MCAT scores was of 507.155.
Step-by-step explanation:
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.
The mean score was 500.0 with a standard deviation of 10.6.
This means that [tex]\mu = 500, \sigma = 10.6[/tex]
Median:
In a normal distribution, the median is the same as the mean, so the median of the MCAT scores was of 500.
First quartile:
This is the 100*(1/4) = 25th percentile, which is X when Z has a pvalue of 0.25. So X when Z = -0.675.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.675 = \frac{X - 500}{10.6}[/tex]
[tex]X - 500 = -0.675*10.6[/tex]
[tex]X = 492.845[/tex]
The first quartile of MCAT scores was of 492.845.
Third quartile:
This is the 100*(3/4) = 75th percentile, which is X when Z has a pvalue of 0.75. So X when Z = 0.675.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.675 = \frac{X - 500}{10.6}[/tex]
[tex]X - 500 = 0.675*10.6[/tex]
[tex]X = 507.155[/tex]
The third quartile of MCAT scores was of 507.155.

gives Keri's monthly loan payment, where r is the annual interest rate and t is the length of the loan, in years.
Explain why the formula is a rational function for a given value of r. What if you are given t?
Answers
Answer:
Keri's monthly loan payment if she gets a 5% loan for 4 years is $300
Step-by-step explanation:
Answer:
It is of the form p(x)/q(x) where p(x) and q(x) are polynomials, and g(x) does not equal 0
If r is given, it does not change the fact that there is still a variable in the denominator.
If t is given, there is no longer a variable in the denominator. The function is still rational, but the case of t being a constant, it is also linear.

A fair coin is flipped 10 times and lands on heads 8 times. Why is there a difference between the experimental and theoretical probabilities of observing 8 heads in 10 coin flips?
A.
Since the number of heads in the 10 coin flips is 8, the theoretical probability of observing a head in a coin flip increases from 0.5 to 0.8.
B.
Since 10 is a large enough number of trials, there is probably some error in the recording of the coin flip outcomes.
C.
The theoretical probability has no basis in reality, so the new probability of flipping heads is now 0.8.
D.
There should be a larger number of trials. With 500 flips of the coin, the experimental probability will likely approach the theoretical probability of 0.5.
Answers
Answer:
Step-by-step explanation:
If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is 1 2. This is also the probability of flipping heads on a coin. And so we have: 1 2 × 1 2 × 1 2 = 1 8. If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. sorry if this isn't right have a nice day.
Answer:
There should be a larger number of trials. With 500 flips of the coin, the experimental probability will likely approach the theoretical probability of 0.5.

The sum of three consecutive numbers is 405. What is the
3rd numbers
Answers
Answer:
136
Step-by-step explanation:
Let the three consecutive numbers be a, a + 1, a + 2
Therefore,
a + a + 1 + a + 2 = 405
3a + 3 = 405
3a = 405 - 3
3a = 402
a = 402/3
a = 134
Third number = a + 2 = 134 + 2 = 136
