1/4 cup is equal to 0.125 pt
Answer:
68
Step-by-step explanation:
We let the random variable X denote the height of students of the college. Therefore, X is normally distributed with a mean of 175 cm and a standard deviation of 5 centimeters.
We are required to determine the percent of students who are between 170 centimeters and 180 centimeters in height.
This can be expressed as;
P(170<X<180)
This can be evaluated in Stat-Crunch using the following steps;
In stat crunch, click Stat then Calculators and select Normal
In the pop-up window that appears click Between
Input the value of the mean as 175 and that of the standard deviation as 5
Then input the values 170 and 180
click compute
Stat-Crunch returns a probability of approximately 68%
<span>On a certain survey it says:
12 out 15 people in the United States prefer eating at the restaurant rather
than home.
To know how many percent is this.
=> 12 / 15
=> 0.8 which is also 80%
Now, the 80% of the those people in the
survey is 400.
Find the total number of people who took
the survey.
Since we already have the 80%, we need to find the number of 20%
=> 400 x 20%
=> 400 x .20
=> 80
=> 400 + 80
=> 480 => the total number of people who took the survey

One of the easier ways of simplifying 0.25/0.75 would be to recognice that 0.25 goes into 0.75 3 times. Thus, 0.25/0.75 = 1/3.
Similary, 6.25/12.5 = 6.25/12.50 = 1/2.
Answer:
C.
Step-by-step explanation:
15+14+13=42
Hope this helps :)
