Answer:

B. Brand A $0.21

Step-by-step explanation:

                                    (round to nearest cent)

Brand A: 21.99/105 = .2094 = .21 ( .2094 rounds to .21)

Brand B: 17.99/80 = .2248 = .22    ( .2248 rounds to .22)

Therefore Brand A is a better buy for $0.21 per load

(-4, -7) and (-6, 9) in slope-intercept form. Show work
BigorU [14]

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

y = mx+b

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

m = \frac{y_2-y_1}{x_2-x_1}

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8

Putting slope in general equation

y = -8x+b

Putting (-6,9) in the equation

9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39

Putting the value of b we get

y = -8x-39

Hence,

Equation of line in slope-intercept form is: y = -8x-39

A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than ex
vredina [299]

Answer:

C. One can be​ 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66

Step-by-step explanation:

Given that the confidence interval is a term that defines a range of values with the probability to contain a population value that has an actual degree of confidence.

This is represented in a situation where population means falls in between upper and lower intervals.

Hence, in this case, the correct interpretation is option C: One can be​ 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66
