Answer:
∠F ≈ 74°
Step-by-step explanation:
The law of cosines is used to find the measures of angles in a triangle when the side lengths are known.
__
f² = g² +h² -2gh·cos(F) . . . . . law of cosines relating to angle F
cos(F) = ((g² +h² -f²)/(2gh)) . . . . . solve for cos(F)
F = arccos((g² +h² -f²)/(2gh)) . . . . . . solve for angle F
F = arccos((10² +62² -60²)/(2·10·62)) = arccos(344/1240)

3 30 page printers, 10 70 page printers
Step-by-step explanation:
x + y = 13
40x+70y = 820
Solving for y in first equation gives: y = 13 - x
Plug into second equation: 40x + 70(13 - x) = 820
40x + 910 - 70x = 820
-30 x = -90
x = 3
Plug into original equation: 3 + y = 13
y must = 10.

5(3 + 4) − 2 = 7 − 3(−2 + 11)
Answers
Answer:
33 = - 20
Step-by-step explanation:
In this equation you have to use BEMA or PEMDAS (however you learned it) ot solve. (Brackets, Exponents, Multiplcation/Divison, Addition/Subtraction) or (Parentheses, Exponents, Multiplication, Division, Addition, SUbtraction)
5(3 +4) - 2 would be simplified down first to
5(7) -2 because parentheses are the first thing you do in any equation like this.
35 -2 because multiplication and divison are next due to the fact there are no exponents
33 because subtraction is last. You then do the same to the other side.
7 -3 (-2 +11)
7 + -3(9) (you can change the minus three to a plus negative three to make the next step more clear)
7 + -27
-20
33 = -20

Answer:
To the nearest degree x is equal to 61.1 degrees.
Step-by-step explanation:
use the trig function cosine.
Cos(theta) = adjacent/hypotenuse.
Let x be the unknown angle in the diagram.
Adjacent = 3
Hypotenuse = 6.2
Cos(x) = 3/6.2
x = [tex]Cos^-1(\frac{3}{6.2})[/tex] (you have to do cos inverse to find x)
X = 61.1
A company surveyed all of the employees in their Columbus, Ohio office,
one of their six national offices. Based on the survey they determined that
72% of all employees were satisfied with their job. Which of the following
explains why this is NOT a random sample?
A. They only surveyed people who had been at their job for five years or
more.
B. They did not survey employees in other offices around the country.
C. The survey was conducted electronically.
D. The survey had a time limit.
Answers
Answer:
B. They did not survey employees in other offices around the country
Step-by-step explanation:
1. A random sample is when you randomly choose options from the whole list. In this case, they make it clear that there are other offices. They didn't give a chance to the rest of the offices to take a survey.
2. Surveying "all" the employees is not what a random sample is. A random sample is supposed to help make it more distributed among the people you survey. Making all of them take it in a cluster is not random.
3. The other choices don't make sense because they don't mention anything about them: nothing about the employees working 5 years, nothing about it being conducted electronically, and nothing about a time limit.
As part of a math lesson on probability, Mr. Keen rolled a standard die 30 times. He predicted the die would land on three 5 times. He actually rolled a three 8 times. What is the percent error for his prediction?
Answers
Using it's concept, it is found that the percent error for this prediciton is of 60%.
What is the percent error?The percent error of an amount is the absolute value of the difference between the actual amount and the expected amount, multiplied by 100% and divided by the expected amount.
In this problem:
The expected amount was of 5 times.The actual amount was of 8 times.Hence, the percent error is given by:
P = |8 - 5|/5 x 100% = 3/5 x 100% = 0.6 x 100% = 60%.
