Oliga [24]3 years ago

Step-by-step explanation:

(a)

the probability of parcels weighing 35oz or less is

0.841

the probability of parcels weighing 14oz or less is

0.023

the probability of parcels weighing between 14 and 35oz is the probabilty of 35oz minus the probability of 14oz

0.841 - 0.023 = 0.818

the percentage is the probability × 100 = 81.8%

(b)

the probability of parcels weighing more than 49oz is 1 minus the probability to weigh less than 49oz.

the probability to weigh less than 49oz is

0.99865

so, the probability to weigh more than 49oz is

1 - 0.99865 = 0.00135

the percentage is again probability×100 = 0.14%

A line with a slope of 2 passes through (3,9). Which choice is an equation of this line?
Veronika [31]

Answer:

The answer to your question is number 3.

Step-by-step explanation:

Data

slope = m = 2

Point = (3, 9)

Process

1.- Write the equation of the line in the form point-slope

               y - y1 = m(x - x1)

2.- Identify the values of x1 and y1

        x1 = 3   y1 = 9

3.- Substitution

               y - 9 = 2(x - 3)

4.- Simplify

              y - 9 = 2x - 6

              y = 2x - 6 + 9

5.- Result

              y = 2x + 3       slope y-intercept form
