your correct answer should be: z = (x - mean) / SD = (79 - 70) / 3 = 3
P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135 i hope this is helpful! :D
Answer:
hey i got that same qustiom=n but i ddint know how to do it
I think the correct given number is 212 base 3 and we are
asked to convert this number into base 2.
We should recall that a number let us say X with a base of
Y can also be written as:
X base Y = log X / log Y
Therefore in this case, the new number base should be
equal to the initial number base. That is:
log 212 / log 3 = log X / log 2
So let us find for X:
log X = (log 212 / log 3) * log 2
X = 10 ^ [(log 212 / log 3) * log 2]
X = 10 ^ (1.467754511
X = 29.36
Therefore the new form would be:

Answer:
8,900
Step-by-step explanation:
Given Number: 8,937.2546
Determine the two consecutive multiples of 100 that bracket 8,937.2546
8,937.2546 is between 8,900 and 9,000
8,950 is the midpoint between 8,900 and 9,000
As illustrated on the number line, 8,937.2546 is less than the midpoint (8,950)
Therefore, 8,937.2546 rounded to the nearest hundred = 8,900
To find 4 out of 10 shaded, we can turn this into a decimal by simply dividing 4 by 10. A rule that many people use is that for every 0 in a 1 with a number of 0’s after it (note that it cannot contain any other numbers), you move the decimal place one to the left. For this, we have 4=4.0 as the decimal is always to the right of the integer. Next, we move the decimal one spot to the left, making our new decimal (and the final answer) 0.40. Unfortunately, however, this is not one of the answers that are possible - I would suggest making sure that 4 out of 10 are indeed shaded (are there 10 out of 10 shaded on the side?) and asking your teacher why 0.4 is not one of the answers.
