<span>The probability that carbon emissions from the company’s factory exceed the permissible level is 35%.
That means the probability that the carbon emissions at within permissible level are 65%
</span><span>The test, which has an accuracy rate of 85%, which means 85% of positive reading has a positive result. The positive reading indicates that the factory's carbon emissions are within the permissible level.
Then, the probability of carbon emissions within permissible level and the reading is positive would be: 65% * 85%= </span><span>0.5525

Answer:
d). 14 and 240
Step-by-step explanation:
According to the Question,
- Given that, The regression model involving 14 independent variables and 255 observations
We need to find out the numerator and denominator freedom degrees
,
k = 14 regression variable
= n - k - 1
= 255 - 14 - 1
= 240 residuals
df=14,240
-
Now The degree of freedom for F-critical is
F_{k,n-k-1}=F_{14,240}
So, The df of the numerator is 14 and df of the denominator is 240

Answer:
3/4 and -3/4
or
0.75 and -0.75
but there is no solution for
10 times the smaller number added to 6 times the larger number to get 3 as result.
the absolute values of x and y must be equal and with opposite signs (due to their sum being 0).
therefore, 10 times the negative value can never be compensated by 6 times the same but positive value. the sum will always be negative and not positive (and therefore not +3).
it only works with 10 times the larger (positive) number plus 6 times the smaller (negative) value.
Step-by-step explanation:
x + y = 0
10×x + 6×y = 3
=>
x = -y
10×(-y) + 6×y = 3
-10y + 6y = 3
-4y = 3
y = -3/4
=>
x = -y = -(-3/4) = 3/4
control :
10×(3/4) + 6×(-3/4) = 30/4 - 18/4 = 3
12/4 = 3
3 = 3
correct
