Slope intercept form: y = 2/3x + 7

Standard form: 2x - 3y = -21

Slope intercept form: y = mx + b ; m = slope and b = y - intercept

Given : A slope of 2/3 and y-intercept of 7

So

The equation in slope intercept form: y = 2/3 x + 7


Standard form: Ax + By = C

y = 2/3 x + 7

Multiply both sides by 3

3y = 2x + 21

Standard form: 2x - 3y = -21

If 12 are boys, then 30(students in class) - 12 (boys) = 18 girls

36 out of 100 randomly selected taxpayers knew about tax incentives for installing energy-saving furnaces. Find a 90% confidence
tresset_1 [31]

Answer:

The 90% confidence interval for the population proportion who knew about the incentives is (0.28, 0.44).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

n = 100, \pi = \frac{36}{60} = 0.6

90% confidence level

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.36 - 1.645\sqrt{\frac{0.36*0.64}{100}} = 0.28

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.36 + 1.645\sqrt{\frac{0.36*0.64}{100}} = 0.44

The 90% confidence interval for the population proportion who knew about the incentives is (0.28, 0.44).

A company’s total cost from manufacturing and selling x units of their product is given by: y = 2x^2 – 600x + 49,000. How many u
AysviL [449]

Answer:

number of units for cost to be minimum=150

Step-by-step explanation:

y=2x^2-600 x+49000

dy/dx=4x-600

dy/dx=0 gives 4x-600=0

4x=600

x=150

d^2y/dx^2=4x

at x=150,d^2y/dx^2=4*150=600>0

so y is minimum at x=150
