The answer would be 0 because each time “x” goes up by 2, “y” also goes up by 5 each time.

x,y
1,-10
3,-5
5,0
7,5

1+2= 3
-10+5= -5

The missing number is 0.

If you study the x values and the y values, you'll see that each time x increases by 2, y increases by 5.

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile

timama [110]

2.86 gallons

Step-by-step explanation:

If 1/35 gallon of gas = 1 mile

To travel 100 miles,

1/35 * 100

= 0.0286 * 100

= 2.86 gallons

Therefore, the car needs 2.86 gallons of gas to travel 100 miles

A statistics professor receives an average of five e-mail messages per day from students. Assume the number of messages approxim

kaheart [24]

Answer:

The probability that on a randomly selected day the statistics professor will have five messages is 0.1755.

Step-by-step explanation:

Let the random variable X represent the number of e-mail messages per day a statistics professor receives from students.

The random variable is approximated by the Poisson Distribution with parameter λ = 5.

The probability mass function of X is as follows:

$P(X=x)=\frac{e^{-5}\cdot 5^{x}}{x!};\ x=0,1,2,3...$

Compute the probability that on a randomly selected day she will have five messages as follows:

$P(X=5)=\frac{e^{-5}\cdot 5^{5}}{5!}$

$=\frac{0.006738\times 3125}{120}\\\\=0.17546875\\\\\approx 0.1755$

Thus, the probability that on a randomly selected day the statistics professor will have five messages is 0.1755.

Math expressions that equal 13

qaws [65]

Step-by-step explanation:

There can be a lot of math expressions that may equal 13. Here are some of the expressions that equal 13.

9 + 4 = 13

15 - 2 = 13

1 × 13 = 13

Now, let us consider some interesting expression

$x^3-x^2+x+7$

If the value of x = 2, then the expression will be equal to 13.

i.e.

$2^3-2^2+2+7=13$ ∵ when x = 2

Considering a word problem

'Tom has 10 oranges while Tony has 3 more oranges than Tom. How many oranges Tony has?

Let 'x' be the number of oranges Tom has.

The number of oranges Tony has = x + 3

as Tom has 10 oranges, so x = 10

Therefore, the number of oranges Tony has = x + 3

= 10 + 3 = 13

Therefore, the number of oranges Tony has = 13
