IF JOHN RAN A 5-KILOMETER MARATHON HOW LONG WAS THAT IN METERS?

Mathematics

lesya [120]3 years ago
7 0
A kilometer is composed of 1000 meters. The term "kilo" means "a thousand."

So 5 kilometers means 5 1000 meters, thus it is equal to 5,000 meters.

1 km = 1000 meters

5 km * 1000 m / km = 5 * 1000 m = 5,000 meters

1 m = 0.001 km

5 km * 1m/0.001km = 5 m / 0.001 = 5,000 meters

Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 100 disks are sum
IrinaK [193]

Answer:

0.84

Step-by-step explanation:

Given that Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 100 disks are summarized as follows:

P(A) = 0.86, P(B) = 0.79, P(A') = 0.14, P(AUB) = 0.95

We are to find out P(A'UB)

We have

P(AUB) =P(A)+P(B)-P(A\bigcap B)\\0.95=0.86+0.79-P(A\bigcap B)\\P(A\bigcap B)=0.70

P(A'UB) = P(A')+P(B)-P(A' \bigcap B)\\= 1-P(A) +P(B)-[P(B)-P(A \bigcap B)]\\= 1-0.86+0.79-P(B)+[tex]P(A'UB)=0.14+0.79-0.79+0.70\\=0.84P(A \bigcap B)[/tex]

What is the expression x - 4 represents a negative integer. What integers could X represent?
zlopas [31]
The expression x-4 will come out to be a negative integer. That means X <em>has to be </em>something that when 4 is taken away from it, the answer is still negative.

Let's try 5.
5-4 is 1. Is 1 negative? No, so that doesn't work.
4-4 is 0. 0 isn't negative either, so that doesn't work.
3-4 is -1. Is -1 negative? YES! Let's try it for 2 as well, just to be safe.
2-4 is -2. Still negative.

X can be anything less than 4.
