Answer: The probability that this student went to Paris = 31%

Step-by-step explanation:

Given: Total students = 100

Students went to Paris = 31

The probability that this student went to Paris = \dfrac{\text{Number of students went to Paris}}{\text{Total students}}

The probability that this student went to Paris = \dfrac{31}{100}

In percent, The probability that this student went to Paris = \dfrac{31}{100}7\times100\%=31\%

Hence, the probability that this student went to Paris = 31%

Slope is -4/5 and passes through the point (2, -3).<br> 5
Natalka [10]

Answer:

y = (-4/5)x - 7/5

Step-by-step explanation:

The general equation of the line is slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept. You have been given the value of the slope (m = -4/5). To find the y-intercept, use the slope and values from the Point (2,-3) to isolate "b".

y = mx + b                                   <----- Slope-intercept form

y = (-4/5)x + b                             <------ Plug -4/5 in "m"

-3 = (-4/5)(2) + b                         <----- Plug in "x" and "y" values from Point

-3 = -8/5 + b                               <------ Multiply -4/5 and 2

-15/5 = -8/5 + b                          <----- Assign common denominator

-7/5 = b                                      <----- Add 8/5 to both sides

Now that you have the slope and y-intercept, you can construct the equation.

y = (-4/5)x - 7/5

makkiz [27]

Answer:

1lb 8 oz

Take 3 lbs and separate it into 48oz + 4 oz = 52 oz.

Same with the 1 lb 12 oz. 16 oz + 12 oz = 28.

Subtract 28 from 52 = 24 oz = 1 lb  8 oz.
