Answer: -18 and -12 degrees Celsius. If one measurement is -18, then 2/3’s of that is -12, 18+12 is -30
Answer:
10 degrees
Step-by-step explanation:
Angles WXZ and ZXY are complementary angles, which always equals 90 degrees. 90 minus 80 equals 10, therefore the measure of angle ZXY is 10 degrees.
Answer:
9
Step-by-step explanation:
x - 3y
Let x =3 and y =-2
3 -3(-2)
3 +6
9
y=mx+b is the standard function for any straight line
y and x are constants, so they never change in the final form
m is the slope, which is given
b is the y intercept, which is not given
we have to plug in the values to find the solution, so plug in the (x,y) coordinates for their respective places in the equation
-8 = (-3/5)(-3) + b
-8 = 1.8 + b
-9.8 = b
now that we have b, we can just put the slope back in for m and get the answer
y= -3/5x -9.8
Answer:
1.16 to 2.75
Step-by-step explanation:
The mean salary (millions of dollars) for shortstops was 1.95.
The population mean for all baseball players was 1.85
The population standard deviation was 1.61.
Formula of confidence interval :
to 
z at 95% confidence level = 1.96
Substitute the values in the formula
Confidence interval :
to 
Confidence interval : 1.16 to 2.75
Hence the 95 percent confidence interval for these data is 1.16 to 2.75
