Let's look at the first one, then you can practice the rest on your own. So, h(0) = - 2 because the number in h() is which number you search for on the bottom row. Then you look at the number above that bottom number, which, in this case is - 2, and that number is your answer.

Lake superior is the largest of the great lakes, with a volume of 2900 mi3. how many gallons of water are contained in lake supe

amid [387]

we are given

Volume of water in lake in mi^3

$V=2900mi^3$

now, we know that

$1 mi^3= 1.10111715*10^{12} gallons$

we can multiply both sides by 2900

$2900*1 mi^3= 2900*1.10111715*10^{12} gallons$

$2900*1 mi^3= 3193.239735*10^{12} gallons$

we can write in scientific form

$2900 mi^3= 3.193239735*10^{15} gallons$ ...........Answer

Consider randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let B

Tems11 [23]

Answer:

0.75

Step-by-step explanation:

Given,

P(A) = 0.6, P(B) = 0.4, P(C) = 0.2,

P(A ∩ B) = 0.3, P(A ∩ C) = 0.12, P(B ∩ C) = 0.1 and P(A ∩ B ∩ C) = 0.07,

Where,

A = event that the selected student has a Visa card,

B = event that the selected student has a MasterCard,

C = event that the selected student has an American Express card,

We know that,

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B) - P(A ∩ C) - P(B ∩ C) + P(A ∩ B ∩ C)

= 0.6 + 0.4 + 0.2 - 0.3 - 0.12 - 0.1 + 0.07

= 0.75

Hence, the probability that the selected student has at least one of the three types of cards is 0.75.
