Answer:
B
Step-by-step explanation:
This is a power to a power problem. -3 times 2 equals-6. Usually when a number is raised to a negative power, the number is the denominator over 1...with the exponent in the denominator ad well. 5 to the -6 power is 15,605 which is the same as 1/5 to the 6th power....1/15,605
Answer: y= -2x + 12
or f (y ) = 6 -
Step-by-step explanation:
just subtract the 2x to get the y alone
Answer: 2^5
Step-by-step explanation: Diego should have added the exponents instead of multiplying them. I know it sounds weird but because both of the numbers are 2's you are able to combine them. When multiplying them together you should keep the base the same and add the exponents. In this case, 2^2 x 2^3 would be 2^5. Hope this helps.
Hey so if every time the minute hand clicks it turns 13.5 degrees and the question is asking us to find the fraction of a circle it covers in a third of a minute we must divide 13.5 by 3.
1) 13.5 / 3 = 4.5 degrees
Now we must find out what fraction of a circle 4.5 degrees is. If a circle is 360 degrees and the minute hand turns 4.5 degrees every third of a minute then we must divide 4.5 by 360 to get our answer.
2) 4.5/60
Finally let's simplify our answer
3) (4.5 / 60) / 1.5 = 3/40
ANSWER: The fraction of the circle the minute hand covers every third of a minute is 3/40
Using the <u>normal distribution and the central limit theorem</u>, it is found that there is a 0% probability of a sample of 50 cars recording an average speed of 66 mph or higher.
In a normal distribution with mean
and standard deviation
, the z-score of a measure X is given by:
- It 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, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
In this problem:
- Mean of 62 mph, hence
. - Standard deviation of 5 mph, hence
. - Sample of 50 cards, hence

The probability of a sample of 50 cars recording an average speed of 66 mph or higher is <u>1 subtracted by the p-value of Z when X = 66</u>, hence:

By the Central Limit Theorem



has a p-value of 1.
1 - 1 = 0.
There is a 0% probability of a sample of 50 cars recording an average speed of 66 mph or higher.
