Simplify the fraction if it is not in it's lowest terms.
Multiply both the numerators to get a new numerator.
Multiply both of the denominators to get a new denominator.

What is the equation in slope intercept form (y=Mx+b) of the line that passes through the point (7, -3) and has a slope of -5?
Mashutka [201]
<h3>Answer:  y = -5x+32</h3>

=========================================

Work Shown:

You can use point slope form by plugging in m = -5 and (x_1, y_1) = (7,-3)

So,

y - y_1 = m(x - x_1)\\\\y - (-3) = -5(x - 7)\\\\y + 3 = -5(x - 7)\\\\y + 3 = -5x + 35\\\\y + 3-3 = -5x + 35-3 \text{ subtract 3 from both sides} \\\\y = -5x + 32\\

---------------

Or you could use y = mx+b to solve for the value of b

Plug in m = -5, and (x,y) = (7,-3)

y = mx+b\\\\-3 = (-5)(7)+b\\\\-3 = -35+b\\\\-3+35 = -35+b+35\\\\32 = b\\\\b = 32\\\\

Since m = -5 and b = 32, we know that y = -5x+32 is the equation of the line.

You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 47%. With Ha : p
rodikova [14]

Answer:

The p-value is 0.0229

Step-by-step explanation:

With H_{a}: p > 0.47 we have an upper-tail alternative. Because the p-value is defined as the probability of getting a value at least as extreme as the value observed. The observed value is given by the test statistic z = 1.997 which comes from a standard normal distribution. Therefore, we compute the p-value in the following way P(Z > 1.997) = 0.0229, i.e., the p-value is 0.0229
