im not 100% but i think its
T= 2t-4+(t-4)+7
Answer: 169.2 per acre are produced if a field is in the top 25%.
Step-by-step explanation:
Given: The mean rain-fed corn yield of harvested fields are normally distributed, produce 147.2 bushels per acre with a standard deviation of 33 bushels per acre.
Let X denote the mean rain-fed corn yield of harvested fields.
Let x denotes the number of bushels per acre are produced if a field is in the top 25%.
Top 25% on a density curve means , (100-25%)i.e. 75% area lies below x.
I.e.
.
Z-score for p-value of 0.75 (one tailed)=0.67 [By z-table]
Then, 
Here approx value is 169.2 (from options).
So, 169.2 per acre are produced if a field is in the top 25%.
Answer:
A 20 and 45
Step-by-step explanation:
son20 & father45
Answer:
b= 55 degrees
c= 125 degrees
Step-by-step explanation:
So angle B and 55 degree angle are vertical angles to they are congruent and opposite
Angle C and angle b =180 so subtract 55 from 180 to get missing angle C as 125 degrees
We conclude that the solution to the given linear equation is x = 15/13.

How to solve that equation for x?</h3>
Here we have the linear equation:
13x - 4 = 11
And we want to solve this for x. To do so, we need to isolate x in one side of the equation.
We can start by adding 4 in both sides, so we get:
13x - 4 + 4 = 11 + 4
13x = 15
Now we can divide both sides by 13, so we get:
13x/3 = 15/13
x = 15/13
We conclude that the solution to the given linear equation is x = 15/13.
