Probability helps us to know the chances of an event occurring. The probability of choosing a black marble from the bowl is 0.2917.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
Probability=(Desired Outcomes)/(Total Number of possible outcomes)
The total number of marbles in the bowl is 24, while it contains 6 white, 8 blue, 7 black and 3 red. Therefore, the probability of choosing a black marble from the bowl is,
P(Black marble) = Number of black marble/Number of total Marble
P(Black Marble) = 7/24 = 0.2917
Hence, the probability of choosing a black marble from the bowl is 0.2917.

Answer:
142 miles
Step-by-step explanation:
We are given the situation that Jill measured the distance from the western border to the eastern border in inches. And we are being asked how many miles is the actual distance.
So first , lets look at what we have.
The inches : 3.375
and our reference point
1 inch = 42 miles
We first look at the reference point, if 1 inch is 42 miles, how much would be 3.375 inches?
Multiply 3.375 by 42
==> 141.75 miles
Now the last sentence asks us to round the nearest whole number.
So look at the number next to one in the ones place and we see that the number is greater than 7, so we round up. Leaving us with the answer :
142 miles
Answer:
Division is not commutative because 25÷5 does not equal 5÷25
Step-by-step explanation:
Answer:
x = 
Step-by-step explanation:
Given
+ 
- 
= 
Multiply through by wxyz to clear the fractions
2xyz + 3wyz - 4wxz = wxy ( subtract wxy from both sides )
2xyz + 3wyz - 4wxz - wxy = 0 ( subtract 3wyz from both sides )
2xyz - 4wxz - wxy = - 3wyz ( factor out x from each term on the left side )
x(2yz - 4wz - wy) = - 3wyz ( divide both sides by (2yz - 4wz - wy )
x = 
( multiply numerator/ denominator by - 1 )
x =
