Answer:

About 121.25

Step-by-step explanation:

<em>Step 1: Interpret x and y</em>

y is the number of accidents that occur = ?

x is the speed = 60 km/h

<em>Step 2: Substitute value of x in the equation</em>

y=0.0875x² - 10.5x + 436.25

y=0.0875(60)² - `10.5(60) + 436.25

<em>Step 3: Find the value of y</em>

y=0.0875(60)² - `10.5(60) + 436.25

y = 121.25

Therefore, the right answer is the last option which is 'about 121.25.'

After you subtract both sides by 4. How can you solve for 3x in this equation?
Nataly [62]

Answer:

B

Step-by-step explanation:

Once you subtract both sides, the 4 is gone then the 10 is subtracted into a 6. You go to the 3x, and just like what you did to the 4 you do the opposite and divide the 3 by itself and the 6 by 3 as well.

In a game, the player wins if he rolls a 2 on a
natima [27]
Since the die is 6 sided, there’s a 1/6 chance he’ll roll a 2. If we divided 100 by 6, it is a 17% success rate.
24 x 17% is 4.08.

He will probably roll successfully 4 times out of 24

Double check: 4/24 can be simplified to 1/6, which is the original probability.
