Old Faithful is a famous geyser at Yellowstone National Park. From a sample with n = 32, the mean duration of Old Faithful's eruptions is 3.32 minutes and the standard deviation is 1.09 minutes. Using Chebychev's Theorem, determine at least how many of the eruptions lasted between 1.14 minutes and 5.5 minutes.
A whole number that is a factor or two or more numbers is called a Composite number
C bc it’s greater that the original
Answer:
41
Step-by-step explanation:
BDA = DBC+CBA
84=5x+3 + 6x-7
Combine like terms
84 = 11x-4
Add 4 to each side
84+4= 11x -4+4
88 =11x
Divide each side by 11
88/11 = 11x/11
8 = x
We want angle ABC
ABC = 6x-7
=6*8 -7
=48-7
=41
Answer:
B. x > 3
Step-by-step explanation:
Well we first simplify the following inequality,
3(8 - 4x) < 6(x - 5)
Distribute
24 - 12x < 6x - 30
Communicative property
-6x
24 - 18x < -30
-24
-18x < -54
Divide -18x by both sides
Which flips the < to a >.
x > 3
<em>Thus,</em>
<em>the answer is B. x > 3.</em>
