Answer:

(10+10)÷(5-3)

Step-by-step explanation:

Always do the parentheses first.

20÷2

Then divide

10

(10+10÷5) -3 is wrong because you do 10÷5 first. That 2 and then +10 is 12. 12-3=9.

Hope this helps!!!

An on-the-job injury occurs once every 10 days on
ExtremeBDS [4]

The probability that the next on-the-job injury will occur within 10, 5, and 1 day are 0.632, 0.393, and 0.095

<h3>What is probability?</h3>

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We know the exponential distribution is given by;

\rm P(X < t)=1-e^{-\dfrac{1}{\mu}t}

The probability that the next on-the-job injury will occur within 10 days:

\rm P(X < 10)=1-e^{-\dfrac{1}{10}10}

P(X< 10) = 0.632

The probability that the next on-the-job injury will occur within 20 days:

\rm P(X < 5)=1-e^{-\dfrac{1}{10}5}

P(X< 5) = 0.393

The probability that the next on-the-job injury will occur within 1 days:

\rm P(X < 1)=1-e^{-\dfrac{1}{10}1}

P(X< 1) = 0.095

Thus, the probability that the next on-the-job injury will occur within 10, 5, and 1 day are 0.632, 0.393, and 0.095

A hot air balloon descends at a rate of 320 feet per minute for 3 minutes. Use integers to calculate and
Amanda [17]
Given:
descends at a rate of 320 feet per minute for 3 minutes.

320 feet per minute * 3 minutes = 960 feet

Total change in altitude is 960 feet. Since it is descending, I believe it would be a negative 960 feet.

What is the slope and y-intercept -4x+2y=-2
natka813 [3]

Answer:

Slope: 2

Y-intercept:  (0, -1) or - 1

Step-by-step explanation:

Given the linear equation, -4x + 2y = -2:

Transform the given equation into its slope-intercept form, y = mx + b:

-4x + 2y = -2

Add 4x to both sides:

-4x + 4x + 2y = 4x - 2

2y = 4x - 2

Divide both sides by 2 to isolate y:

\frac{2y}{2} = \frac{4x - 2}{2}

y = 2x - 1 ⇒ This is the slope-intercept form where the slope, m = 2, and the y-intercept is (0, -1).
