Answer:
t=1
Step-by-step explanation:
combine the one t and the 4t
16-2t=5t+9
subtract the 16
-2t=5t+9-16
-7t=9-16
-7t=-7
t=1
Um I actually don’t know the answer I just need coins have a good day maam or sir there is the answer
Answer:
Nifal received $ 4 for washing the first car.
Nifal received $ 5 for washing the second car.
4 and 5 have a sum of 9.
Step-by-step explanation:
The problem can be rewritten as follows: Find the sum of two consecutive entire numbers equal to 9. That is:
Then, by eliminating y:
Now, let is clear 
:
Nifal received $ 4 for washing the first car.
The earning for the second car is: ()
Nifal received $ 5 for washing the second car.
4 and 5 have a sum of 9.
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
