The slope of the line y=\frac{3}{5} x-1 is m=\frac{3}{5}.

The line perpendicular to the above line has slope -\frac{1}{m} =-\frac{5}{3}

Its equation is y=-\frac{5}{3} x+c. Since this line passes through, (-9,4),

4=-\frac{5}{3} )(-9)+c\\ c=-11

Thus the equation of the line in slope intercept form is y=-\frac{5}{3} x-11

An HMO pamphlet contains the following recommended weight for women: "Give yourself 100 pounds for the first 5 feet plus 5 pound
fenix001 [56]

Answer: 5 feet and 7 inches

Step-by-step explanation:

"Give yourself 100 pounds for the first 5 feet plus 5 pounds for every inch over 5 feet tall"

100 pounds for 5 feet + 5 pounds/inch [over 5 feet]

We can separate 135 pounds into two parts: the first 100 pounds and the other 35 pounds: 135 = 100 + 35

100 = 5 feet

35 pounds/5 pounds/inch = 7 inches

So, the height is 5 feet and 7 inches

Question 3. Find the distance between P(4,5) and the line with equation 8x + 5y = 20​
earnstyle [38]

Answer:

Step-by-step explanation:

8x+5y = 20

y = (-8/5)x + 4

slope of the line is -8/5.

slope of any perpendicular to the line is ⅝.

line of slope ⅝ that passes through P(4,5):

y-5 = ⅝(x-4)

y = ⅝x + 2.5

find intersection of lines

⅝x + 2.5 = (-8/5)x + 4

25x + 100 = -64x + 160

89x = 60

x = 60/89, y = 260/89

distance between (60/89, 260/89) and (4,5) = 3.92

The conditional relative frequency table below was generated by column using frequency table data comparing the number of calori
inessss [21]

Answer:

B. There is an association because the value 0.15 is not similar to the value 0.55

Step-by-step explanation:

Based on the above picture, for the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.

The conditions that satisfy whether there exists an association between conditional relative frequencies are:

1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.

2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.

For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45

We can conclude that there is an association because the value 0.15 is not similar to the value 0.55
