Answer:
There are 342 different combinations.
Step-by-step explanation:
Ok, Aileen is choosing toppings for a pizza.
She can choose two.
There are 19 options that can be chosen once.
The first thing we need to do, is find all the "selections".
Here we have two selections:
Topping number 1
Topping number 2.
Now we need to find the number of options for each one of these selections:
Topping number 1: Here we have 19 options.
Topping number 2: Here we have 18 options (because one was already taken in the previous selection)
The total number of combinations is equal to the product between the numbers of options.
C = 19*18 = 342
There are 342 different combinations.
Answer:
If i was to read this out loud, i would say: 5 plus the quantity of 17 minus 8.
Step-by-step explanation:
5 + (17-8)
Parenthesis need to be done first! That is why you need to say 'the quantity of...' You also have to add 5 to it all, and you might as well do it before 'the quantity of...' becuz it comes before it in the numerical expression.
YAY! ! ! YOU GOT IT!!! =)
<u>Answer-</u>
A 95% confidence interval for the true percent of movie goers is 36.41% to 44.25%
<u>Solution-</u>
Given,
n = 600 (sample size)
x = 252 (number of people who bought)
Confidence interval = 95%, so z = 1.96
We know that,
where,
M = sample mean
Z = Z statistic determined by confidence level
SE = standard error of mean
Calculating the values,
from the tables
Putting all the values in the formula,
W=width of the pasture, and
<span>320000/w=length (parallel to river) </span>
<span>F=twice width + length </span>
<span>=2w + 320000/w </span>
<span>Find derivative of F with respect to w and equate to zero to find w. </span>
<span>i.e. </span>
<span>Solve for w in </span>
<span>dF/dw=0
hope it helps</span>
