<h3>Answer:  3/5</h3>

Work Shown:

3 blue + 3 red = 6 pens that are either blue or red

4 black + 3 blue + 3 red = 10 pens total

6/10 = 3/5 is the probability of selecting either blue or red

3/5 = 0.60 = 60%

"In the diagram, m = 128° and m = 76°. What is mABC?
wel
Angle ABC is an inscribed angle.

Inscribed angle = 1/2 * Intercepted Arc

The intercepted arc is arc CD + arc DA, which would be 128 + 76 = 204

m<ABC = 1/2(204)

m<ABC = 102 degrees

You answer is D) 102

A boat travels at a constant speed. After 20 minutes, the boat has traveled 2.5 miles. The boat travels a total of 10 miles to a
monitta
In order to find the speed at which the boat is traveling, we divide the distance it has traveled by the time elapsed:

2.5/20=0.125 miles/minute

Next, we want to find how long it took for the boat to travel 10 miles. Since it travels 0.125 miles every minute, we just divide:

10/0.125=80

Thus, it took 80 minutes for the boat to reach the bridge

Find the means of these numbers 3,7,2,9,4,7,3,7,5,2
Sholpan [36]

The "mean" of a group of numbers is also called their "average".

To calculate the mean, add up all the numbers, then
divide the sum by the number of items on the list.

Step #1:  Addum up:  3+7+2+9+4+7+3+7+5+2 = 49

Step #2:  Count the number of items on the list:  I count 10 .

Step #3:  Divide the sum by the number of items on the list.

                 49 / 10  =  4.9

The mean (average) of the numbers on that list is  4.9 .

look at the table of x and y (1-3) (2-7) (3-11) which equation is represented by the table a)y=2x+1 B)y=3x+2 C) y=4x-1 D)5x-3
Nostrana [21]
(1,3) , (2,7), and (3,11):
Let's find the slope m between (1,3) and (2,7)
Slope = Rise / Run
m = (7-3) / (1)
m = 4.

Our equation y=mx +b  has a slope of 4. Since C is the only option that satisfies this, we already know the answer, but let's find the y-intercept.
y = mx + b.       Plug in 4 for m, and the first coordinate (1,3) for x and y
3 =4(1) + b       Subtract 4 from both sides
b = -1
Our function is y =4x - 1
Answer is C) y=4x-1
