Step-by-step explanation:
trinomial has 3 sides cubic has 4 sides
Answer:
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Step-by-step explanation:
We are told she would like to have at least 40 cupcakes and cookies combined.
If a is number of cupcakes and b is number of cookies, then this inequality is;
a + b ≥ 40
Secondly, we are told she would like to have at most 5 more cupcakes than cookies.
Thus, the inequality is;
a + 5 ≤ b
Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50
Thus, the inequality is;
2.50a + 1.50b ≤ 105
Finally, the 3 inequalities are;
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Answer: 0.9608
Step-by-step explanation:
Given : A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that
Mean :
Standard deviation :
Sample size :
Let be the sample mean.
The formula for z-score in a normal distribution :
For
The P-value =
Hence, the probability that their mean rebuild time is less than 8.9 hours is 0.9608 .
Answer:
A. 11
Step-by-step explanation:
The average rate of change of the given function over the interval [2,6] is simply the slope of the secant line connecting the point (2,f(2)) and (6,f(6)).
This implies that, the average rate of change over [2,6]
From the table f(6)=71
Since we want the average rate of change to be 15, we have;
This implies that;
The correct choice is A.
