Answer:
The correct value is t* = 2.797.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a two-tailed confidence level of 
. So we have T = 2.797.
Answer:
∠A = 88°
∠B = 92°
∠C = 88°
∠D = 92°
Step-by-step explanation:
∠A + ∠B = 180°
(2x + 4) + (3x - 34) = 180
reduce:
5x - 30 = 180
5x = 210
x = 42
∠A = 2(42) + 4 = 88°
∠B = 3(42) -34 = 92°
∠C = ∠A = 88°
∠D = ∠B = 92°
Answer:
Step-by-step explanation:
Lets calculate the fence first!
15*12=180
Mario needs to paint 180 ft^2
Turn this into a linear equation
250x=180
Divide by 250 on both sides:
x=0.72
So, Mario needs 0.72 Gal of paint to paint the fence!

The value of x and y is y= 3/4 and x= -1/2
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given equations:
2x+8y=5........(1)
24x-4y=-15...........(2)
Multiply equation (1) by 12, we get
24x + 96y = 60.....(3)
From (2) and (3), we get
-4y-96y= -15-60
-100 y= -75
y= -75/-100
y= 3/4
and 2x+8y=5
2x + 8 (3/4) =5
2x + 6 = 5
2x= -1
x= -1/2
