Answer:
2(x-√a)² + x - √a +1
Step-by-step explanation:
use x-√a as value for x
f(x-√a) = 2(x-√a)² + x - √a +1
Number of lawn mowing = x.
His cost per lawn for fertilizer = $6.
His cost per lawn for labor = $14.
Total cost per lawn for fertilizer and per lawn for labor for him = 6+14 = $20.
He charges = $25 per lawn.
So, profit per lawn = 25 - 20 = $5.
Therefore, for mowing x number lawn could be represented by polynomial that represents his weekly profit.
<h3>a) P(x) = 5x.</h3>
b) For mowing 40 lawns per week total profit would be
P(40) = 5(40) = $200.
c) Number of weeks an year = 52.
Therefore,
<h3>Annual profit is 52 * 200 = $10400.</h3>
Answer:
The mean for the sampling distribution of the sample proportion is 0.29
The standard deviation for the sampling distribution of the sample proportion is 0.01435
Step-by-step explanation:
The mean for the sampling distribution of the sample proportion is always equal to the true population proportion, in this case; p = 0.29
The standard deviation for the sampling distribution of the sample proportion is calculated as;
Using the given values;
p = 0.29
1 - p = 0.71
n = 1000
The standard deviation becomes;
The s.d becomes 0.01435
Set P = {x, 4, 6, 10, -2, x, 6, 1, x} In set P, if the value of x is 4 greater than the largest numerical value present, what is
Tomtit [17]
Answer:
The range of the data set is 16
Step-by-step explanation:
The range of a data set is given by R = Maximum - minimum, within the values of the data set. In the given set P, the highest numerical value is 10, therefore, a greater value in 4 units than the greatest numerical value present is 14, which is represented by x. With this, the maximum value of the data set is 14 and the minimum value of the data set is -2.
Range = Maximum - minimum = 14 - (-2) = 16
Conclusion: The range of the data set is 16
