First lets get the formula for a triangular prism
First lets plug in our numbers
It really doesnt matter how you multiply everything, but you end up with 119cubic feet.
Answer:
a)False: In a sample of 100 men who are heavy smokers, exactly 24 of them will contract lung cancer.
b)True: In a sample of 100 men who are heavy smokers, the number who will contract lung cancer is likely to be close to 24.
c)True: As more and more heavy-smoking men are sampled, the proportion who contract lung cancer will approach 0.24. Circle one: TRUE FALSE
3/5 of the total responses expected = 87...
3/5x = 87
x = 87 / (3/5)
x = 87 * 5/3
x = 435/3
x = 145 <=== what was expected
8.213, 8.214 just add 1 hundred to the end
Supplementary angles are two angles that add up to 180°.
STEP 1:
find the value of x
x= smaller angle
10x + 48= larger angle
Add the two angles above to equal 180.
x + (10x + 48)= 180
combine like terms
11x + 48= 180
subtract 48 from both sides
11x= 132
divide both sides by 11
x= 12° smaller angle
STEP 2:
find the value of the second angle
=10x + 48
=10(12) + 48
=120 + 48
=168° larger angle
CHECK:
12° + 168°= 180°
180°= 180°
ANSWER: The smaller angle is 12° and the larger angle is 168°.
Hope this helps! :)
