Which of the sums below can be expressed as 6(3 + 9)? 18 + 54, 18 + 9, 9 + 15, 6 + 54?

alisha [4.7K]

The answer would be 18+54 because when you distribute the 6 to the numbers that are inside the parenthesis (6*3=18 6*9=54) When you add 18 and 54 together I would get 72. 18+54 is 72. 18+9 is 27. 9+15 is 24. 6+54 is 60. Pick the one that gives you an answer of 72 which was 18+54. I hope this helped you!

Nour drove from the Dead Sea up to Amman, and her altitude changed at a constant rate. When she began driving, her altitude was

attashe74 [19]

Answer:

y = 700x - 400

Step-by-step explanation:

A negative number represents an altitude below sea level.

Beginning: -400

y = mx + b

y = mx - 400

In 2 hours the altitude was now 1000 m.

1000 m - (400 m) = 1400 m

The altitude went up 1400 m in 2 hours. The rate of change is

1400/2 m/h = 700 m/h

The rate of change is the slope.

y = 700x - 400

Three times a certain number is added to 5 and the result is 20? <br> What's the number?

FinnZ [79.3K]

Answer:

The number is 5

Step-by-step explanation:

First of all we have to convert the given scenario in mathematical or algebraic expression.

Let x be the number

Then according to given statement, the equation will be:

"Three times a certain number"

$3x$

"is added to 5"

$3x+5$

"the result is 20"

$3x+5 = 20$

Using Subtraction property of Equality

$3x+5-5 = 20-5\\3x = 15$

Using division property of equality

$\frac{3x}{3} = \frac{15}{3}\\x = 5$

Hence,

The number is 5

The interarrival time of nuclear particles in a Monte Carlo simulation of a reaction is designed to have a uniform distribution

jekas [21]

Answer:

Incomplete question, but you can use the formulas given to solve it.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

Uniform distribution over an interval from 0 to 0.5 milliseconds

This means that $a = 0, b = 0.5$

Determine the probability that the interarrival time between two particles will be:

Considering $a = 0, b = 0.5$ , and the question asked, you choose one of the three formulas above.
