Answer
B
Step-by-step explanation:
because it has to be less than according to the word problem and using common sense I know that if there are more than 1 of a number as an answer choice that means that it is most likely the answer
Answer:
The total number of students that ate lunch are 300 .
Step-by-step explanation:
Formula
As given
There are 4 lunch choices in a school cafeteria: Salad, Pizza, Spaghetti, and Sub Sandwiches.
The percentage of students that chose salad is 15%.
If 45 students chose salad.
Here
Percentage = 15%
Part value = 45
Put in the formula
Therefore the total number of students that ate lunch are 300 .
Answer:
Step-by-step explanation:
There are two sides on a coin, heads and tails. So, the probability of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.
Where is the rest of the question
Answer:
<h2>25 months</h2>
Step-by-step explanation:
Using the formula for calculating the standard error of the mean to get the standard deviation. The standard error of the mean is expressed as;
SE = S/√n where;
S is the standard deviation
n is the sample size
Given SE = 25 months and n = 1, on substituting this parameters into the formula, we will have;
25 = S/√1
25 = S/1
cross multiply
S = 25*1
S = 25 months
<em>Hence the standard deviation based on the sample is 25 months</em>
