Answer:8,000
Step-by-step explanation:
Do you would take 500 times 16. 6 times 0 is 0, do that one more time until you’re at the 5. So, 6 times 5 is 30. Put the 3 over the 5 and the 0 under the line. Drop a 0 and do 1x0 twice. 1x5 is five. Plus 3 is 8. Add all of the numbers together, getting the number of 8,000!
The error is that the student put a decimal point in between the 9 and 3 instead of a multiplication sign.The answer is 9x3
Answer:
Choice A: -36 + (-8)
Step-by-step explanation:
We want to find the equivalent expression to -36 - 8
The correct option is Choice A.
Choice A is -36 + (-8)
The reason is that the product of the signs + and - is -, i.e.
+ * - = -
Hence, + (-8) is the same thing as -8 and Choice A becomes -36 - 8
Answer:
The answer is
<h2>8.6 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(8,9) and (3,2)
The distance between them is

We have the final answer as
<h3>8.6 units to the nearest tenth</h3>

Answer:
a) P(X<50)=0.9827
b) P(X>47)=0.4321
c) P(-1.5<z<1.5)=0.8664
Step-by-step explanation:
We will calculate the probability based on a random sample of one moped out of the population, normally distributed with mean 46.7 and standard deviation 1.75.
a) This means we have to calculate P(x<50).
We will calculate the z-score and then calculate the probability accordign to the standard normal distribution:

b) We have to calculatee P(x>47).
We will calculate the z-score and then calculate the probability accordign to the standard normal distribution:

c) If the value differs 1.5 standard deviations from the mean value, we have a z-score of z=1.5

So the probability that maximum speed differs from the mean value by at most 1.5 standard deviations is P(-1.5<z<1.5):
