Answer:
C.) 2 1/2
Step-by-step explanation:
X + 2 1/4 = 4 3/4
Change the fractions to improper fractions .
We have
X + 9/4 = 19/4
Subtract 9/4 from both sides
X + 9/4 - 9/4 = 19/4 - 9/4
X = 19/4 - 9/4
Look for the LCM of the denominators.
The LCM is 4
Divide the LCM by the denominators and multiply the results by the numerators, the lcm becomes the denominator of the results.
That’s
X = 19 - 9 /4
= 10/4
Divide both numerator and denominator by 2
= 5/2
= 2 1/2
Answer:
We can approximate to normal.
The parameters of the approximate normal distribution are:


It is not unusual to have 23 or more successes. The probabiltity of this event happening is 13.4%.
Step-by-step explanation:
To approximate the binomial distribution to a normal distribution, we can calculate n*p and n*q and if both are bigger than 5 we can do the approximation.

We can approximate to normal.
The parameters of the approximate normal distribution are:

The continuity correction factor is used because the binomial is a discrete function and the normal a continous function.
The probability of 23 successes must be expressed in the normal distribution as:

It is not unusual to have 23 or more successes. The probabiltity of this event happening is 13.4%.
Answer:
your answer would be 60.
Step-by-step explanation:
when finding surface area, you have to multiply all your values to get the answer.
Given number = 0.44
Find how many times the value of the hundredths place digit to the value
of the tenths place digit.
=> Since this is a decimal number, I believe, the value you mean is
tenths and hundredths, not tens and hundreds.
Now, how many times is the value of each digit differs from each other:
The answer is 10 times
=> 4 hundredths x 10 = 4 tenths
=> 0.04 x 10 = 0.4, which is correct
