Answer:
The measure of the third angle is 92°
Step-by-step explanation:
We first have to make an equation that represents this equality. To do it we simply have to add the values that give us with x and this will result in 180 °
15° + 73° + x = 180°
once we have the equation what we have to do is solve x, so we will pass all the terms that are adding to x by subtracting 180
x = 180° - 73° - 15°
now that we have cleared the x we only have to perform the indicated operation and we will obtain the value of x
x = 92°
The measure of the third angle is 92°
Answer:
y=2x*6
Step-by-step explanation:
Answer:
the range is {7,5,1}
Step-by-step explanation:
To find the range, just plug in the domain into the function.
f(-1) = -2(-1) + 5 = 7
f (0) = -2(0) + 5 = 5
f(2) = -2(2) + 5 = 1
Answer:
Step-by-step explanation:
The firm tests 75 parts, and finds that 0.25 of them are notusable
n = 75
x = 0.25 \times 75 = 18.75≈19
Confidence level = 95%
So, Z_\alpha at 95% = 1.96
Formula of confidence interval of one sample proportion:
