Answer:
Yes, but can be simplified to
Step-by-step explanation:
Since slope is the formula to determine the equation of a line, we use,
In this sense, we can see that the rise is -2
The run, or how far along the x-axis the line goes until it reaches its desired point is 8.
Although you are correct in the , don't forget to use your GCF to determine how low the fraction can go. (GCF or greatest common factor of 2 in this case) to get
I hope this answer finds you well, and I would be happy to help you again in the future! :D
Answer:
13/15
Step-by-step explanation:
I assume you mean the ratio 4/5 : 12/13
Ratio means division, so it's 4/5 / 12/13
Multiply by reciprocal: 4/5 * 13/12 = 13/15
They get 550 miles closer per hour. 900/550=1.636363.... They will meet after 1.64 hrs
The mistake is in step 4. It's correct up to step 3. Step 3 shows: $293.25 * 1/6 (this is correct) Now you must multiply $293.25 by the fraction 1/6, which is the same as dividing $293.25 by 6. Instead, in step 4, $293.25 was multiplied by 6. Step 4 is the mistake.
Theorem: If a random variable is normally distributed with a mean of µ and a standard deviation of σ, then the sample mean with a sample size of n would be normally distributed too with the same mean and a standard deviation of
.
In this case, µ = 1200, σ = 60, sample size n = 36.
So the sample mean has a mean of 1200 and a standard deviation of
.
Then the z-score that corresponds to 1224 is
