Area is equal to length times width, so we can use this over here:
Area = lw
Area = (x+7)(x+1)
Area = x^2+x+7x+7
Area = x^2+8x+7
Hope this helps!! :)
Hi lovely,
The answer you're looking for would be 76.7
.59x130 = 76.7
We will see that the probability of x taking on a value between 75 to 90 is P = 0.5
<h3>
How to get the probability?</h3>
We know that x is a continuous random variable uniformly distributed between 65 and 85.
This means that the probability that x value y in the range is such that:
1 = P(y)*(85 - 65) = P(y)*20
1/20 = P(y).
Now, the probability of x taking a value between 75 and 85 is:
P(75 to 85) = (1/20)*(85 - 75) = 10/20 = 0.5
And the probability between 85 and 90 is zero (because the maximum value that x can take is 85, so this part does not affect).
Then we conclude that the probability of x taking a value between 75 to 90 is:
P(75 to 90) = P(75 to 85) + P(85 to 90) = 0.5 + 0 = 0.5

The related number sentence that shows the commutative property addition for the equation 3+ 9 + 12 is 9 + 3 = 12
Please take note, the commutative property of addition is
a + b = c
b + a = c
a + b = b + a
Commutative originates from the word move around or commute, therefore, commutative property refers to the act of moving stuff around. In addition, the rule is a + b = b + a; wherein from the example above, means 9 + 3 = 3 + 9. They want to say that the computation uses the Commutative Property, if at any time, a computation depends on moving stuff around
