Consider that the slope-intercept form of the straight line with slope (m) and y-intercept (c) is given by,
a.
Modify the given equation as,
Thus, the equation in slope-intercept form can be written as,
b.
Modify the given equation as,
Thus, the equation in slope-intercept form can be written as,
c.
Modify the given equation as,
Thus, the equation in slope-intercept form can be written as,
Answer: 2 is the y intercept
Step-by-step explanation:
Slope is rise over run and in this problem our y intercept is 2 because it is defined as the y. Negate your 9 and put it over the y intercept to make into a fraction to represent slope. This makes it y = mx + b form now.
y = - 9/2x + 2

Answer:
0.4967<p<0.6033
Not effective
Step-by-step explanation:
given that a clinical trial tests a method designed to increase the probability of conceiving a girl.
In the study 580 babies were born, and 319 of them were girls
Sample proportion p=
Standard error of proportion p =
Margin of error for 99%= Z critical * std error=
(Since sample size is large Z value is used)
Confidence interval 99%
=
0.4967<p<0.6033
This method appears to be not effective as the confidence interval 99% contains 0.50 indicating probability for girls is still 0.50
Answer:
Cost of procedure is $45
Step-by-step explanation:
In this question, we are concerned with finding the cost of the procedure, given the tip amount and the percentage of which it is of the procedure cost.
From the question, we are told that the cost of the procedure is b
Mathematically, 12% of b = tip
Thus,
12/100 * b = 5.4
12b = 5.4 * 100
12b = 540
b = 540/12
b = $45
