Answer:
11
Step-by-step explanation:
X+8=19
X=19-8
X=11
If the storybook cost $20, and it was also 2/5 of his money, then 2/5 of his money is $20. In other words:
2x/5 =20.
Multiplying both sides by 5, we get:
2x = 100.
If we divide both sides by 2, then we're left with:
x = 50.
David had $50 at first.
Answer:
10.8 feet
Step-by-step explanation:
Multiply 4/5 by 2 on the top and bottom. Then you'll get 8/10 which is 0.8 as a decimal
Answer: Value of CE = 6.
Explanation:
Since we have given that
AE=4
BE=3
DE=2
Let CE be x.
As we know that
When two chords intersect each other inside a circle, the products of their segments are equal.
Here, we can see that each chord is cut into two segments at the point of where they intersect.
So,
Hence, value of CE = 6.
The probability that a region prone to hurricanes will be hit by a hurricane in any single year is one tenth or 0.1
P(at least one) = 1 - P(none in five years)
-----
= 1 - 0.90^5
= 1 - 0.59049
=0.40951 or 0.41.
41% probability that there will be a hurricane at least once in the next 5 years.
