let's evaluate :

$(a - 2b) {}^{3}$

$\{ - 2 - (2 \times - 12) \}$

$\{ - 2 - ( - 24)\}$

$\{ - 2 + 24 \}$

What is the equation of the line? Write in standard form. (4,5).

dezoksy [38]

Answer:

$\large\boxed{5x+4y=20}$

Step-by-step explanation:

The equation of a line in slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

We have the x-intercept = 4 → (4, 0), and y-intercept = 5 → b = 5.

Therefore we have the equation:

$y=mx+5$

Put the coordinates of x-intercept to the equation:

$0=4m+5$ subtract 4m from both sides

$-4m=5$ divide both sides by (-4)

$m=-\dfrac{5}{4}$

Finally we have the equation of a line if slope-intercept form:

$y=-\dfrac{5}{4}x+5$

The standard form:

$Ax+By=C$

Convert:

$y=-\dfrac{5}{4}x+5$ multiply both sides by 4

$4y=-5x+20$ add 5x to both sides

$5x+4y=20$

A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the

kolbaska11 [484]

The probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

The true proportion (p) is given to be 0.03.

Therefore, Mean (μ) = p = 0.03.

The standard error of sampling distribution can be calculated using the formula σ = √[{p(1 - p)}/n], where n, is the sample size, that is, n = 476.

Therefore, σ = √[{0.03(1 - 0. 03)}/476] = 0.00782.

Since, np = 14.28 and n(1 - p) = 461.72 are both greater than 5, we assume the sample is normally distributed.

Since, we are asked to find the probability that the sample proportion is less than 0.04, we using our calculator, enter as following:

Normalcdf(-100000000,0.04,0.03,0.00782), which gives us the value 0.8995 or 89.95%.

Thus, the probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.
