18+24+19+n=82. solve for n. after you solve for n your answer would be 21. the jar would contain 21 chocolate candies.
For this case what you can do is an average to calculate the number of hours it will take them to work together:
Let
t: average time.
hi: hours worked for each one.
n: number of teams.
The average will be given by:
t = (h1 + h2) / (n)
Substituting both values:
t = ((15) + (10)) / (2) = 12.5
answer
it would take 12.5 h to pave that same section of highway if both crews worked together
Answer:
The critical value is ![T_{c} = 1.415](https://tex.z-dn.net/?f=T_%7Bc%7D%20%3D%201.415)
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 8 - 1 = 7
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 7 degrees of freedom(y-axis) and a confidence level of
. So we have T = 1.415.
The critical value is ![T_{c} = 1.415](https://tex.z-dn.net/?f=T_%7Bc%7D%20%3D%201.415)

When finding the area of a figure, you need to multiply. The area has sides of 4 4/9 and 2 1/5. We can multiply these fractions to find the area.
[] Step 1: Convert the mixed fraction to an improper fraction (An improper fraction is when the numerator is bigger than the denominator). []
4 4/9 = 40/9
2 1/5 = 11/5
[] Step 2: Multiply across []
40 * 11 = 440
9 * 5 = 45
= 440 / 45
[] Step 3: Turn the improper fraction into a mixed number (In other words, simplify). []
440 / 45 = 9 7/9

Have you learned PEMDAS? (Parenthesis, exponents, multiplication, division, addition, subtraction). That is what I am going to do here.
The first parenthesis, let's solve. 7*10=70-5=65
The second parentheisis: I am assuming the negative sign is a typo, and this answer will be off if it is not. Sorry. 5*10=50
65*50=3250
I hope this helps, and let me know if you need further assistance.
