Answer:
B. 66
Step-by-step explanation:
idk how to explain it without repeating what it says in the answer
Answer:
The answer is:
B) 66 degrees
Step-by-step explanation:
Since the triangle is an isosceles triangle, angle C is the same as angle B.
57 + 57 = 114
Since you know two of the three angles, and you know that a triangle's angles must equal 180 degrees...
180 - 114 = 66
Angle A must equal 66 degrees for the triangle to equal 180 degrees.

An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in Texas. He believes that the mean income is $24.6, and the standard deviation is known to be $7.9. How large of a sample would be required in order to estimate the mean per capita income at the 80% level of confidence with an error of at most $0.56? Round your answer up to the next integer.
Answer:
327
Step-by-step explanation:
Calculation for How large of a sample would be required in order to estimate the mean per capita income
First step is to find z 80% confidence level
At 80% confidence level the z will be:
α/2 = 1 - 80% = 1 - 0.80 = 0.20
α/2= 0.20 / 2 = 0.01
Zα/2= Z0.01= 1.28 from z table
Now let calculate the Sample size using this formula
Sample size = n= [( Zα/2* σ ) / E]^2
Let plug in the formula
n = (1.28*7.9/0.56)^2
n= 326.06
n=327 (Approximately)
Therefore How large of a sample would be required in order to estimate the mean per capita income will be 327

Determine the intercepts of the line.
y = 80 - 18
Answer:
Step-by-step explanation:
This equation is in slop-intercept form. This means that the y-int is in the equation, it will always be the constant, so y is -18.
To find x, set y to 0.
0 = 8x - 18
18 = 8x
18/8 = x
9/4 = x

If the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that the equations are,
y=3x+14 ----------(1)
y= -4x -------------(2)
In order to solve "by substitution," you must first solve one of the equations for one of the variables (you choose which one), plug that solution back into the other equation, "substituting" for the selected variable and then solve for the other.
Substitute the value of y from equation 2 in equation 1 as
y=3x+14
-4x=3x+14
Rearrange the equation in order to find the value of x as
-4x-3x=14
-7x=14
x= -14/7
x= -2
Put the value of x in equation 2 as
y= -4x
y= -4(-2)
y=8
Thus, if the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.

I need help with this, Its geometry
Answer:
Step-by-step explanation:
x + 17 + 6x + 10 + 4x - 34 = 180
11x + 27 - 34 = 180
11x - 7 = 180
11x = 187
x = 17
x + 17 = 17 + 17 =34
6(17)+10 = 102 + 10 = 112
4(17) - 34 = 68 - 34 = 34
