3 gallons in 15 seconds would be 3/15

so for 1 gallon 15/3 = 5

it would be 1 gallon every 5 seconds so 1/5

Let X denote the number of bars of service on your cell phone whenever you are at an intersection with the following probabiliti

ZanzabumX [31]

Answer:

a. $P(2 \leq X \leq 3) = 0.5$

b. $P(X \geq 1) = 0.9$

c. $P(X < 2) = 0.25$

d. $P(X > 3) = 0.25$

Step-by-step explanation:

We are given the following distribution:

$P(X = 0) = 0.1$

$P(X = 1) = 0.15$

$P(X = 2) = 0.25$

$P(X = 3) = 0.25$

$P(X = 4) = 0.15$

$P(X = 5) = 0.1$

a. Two or three bars

$P(2 \leq X \leq 3) = P(X = 2) + P(X = 3) = 0.25 + 0.25 = 0.5$

Thus:

$P(2 \leq X \leq 3) = 0.5$

b. At least one bar

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1 = 0.9$

Thus:

$P(X \geq 1) = 0.9$

c. Fewer than two bars

$P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.15 = 0.25$

Thus:

$P(X < 2) = 0.25$

d. More than three bars

$P(X > 3) = P(X = 4) + P(X = 5) = 0.15 + 0.1 = 0.25$

Thus:

$P(X > 3) = 0.25$

What is the are of this?

aliya0001 [1]

Answer:

Ok first of all you start out splitting the shape into seperate rectangles, in this case 2. take those 2 rectangles and find the area of them. Say we start from the smaller rectangle. 2 x 4 = 8 so the area of the smaller rectangle is 8. Keep that in mind. Next we have to multiply 10 x 5 because that is the labeled number of meters and that equals 50. So add 50 + 8 = 58

Step-by-step explanation:

Your answer is 58 meters

Really hope i helped and have a wonderful day! :)

When 5 is added to a set of 3 numbers the mean increases to 4.6. What was the mean of the original 3 numbers?

SVEN [57.7K]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Multiply 4.6 by 4 to get the sum of the numbers after 5 was added:

4.6 x 4 = 18.4

^ This is the new total

Subtract 5 from this:

18.4 - 5 = 13.4

Divide this value by 3 to get the original mean:

13.4/3 = 67/15
