There are two spinners containing only black and purple slices.Spinner A has 3 black slices and 12 purple slices.
All the slices are the same size.
Spinner B has 2 black slices and 6 purple slices.
All the slices are the same size.
Each spinner is spun.
List theseſevents from least likely to most likely.
Event 1: Spinner B lands on a black slice.
Event 2: Spinner A lands on a black slice.
Event 3: Spinner B lands on a black or purple slice.

Answer 1

Answer:

Answer:

Event 4, Event 2, Event 1, Event 3 (least to most likely)

Step-by-step explanation:

Let's take a look at each event:

Event 1- Spinner B lands on a black slice.

2 black slices, 8 total slices

2/8=1/4=25% probability

Event 2- Spinner A lands on a black slice.

3 black slices, 15 total slices

3/15=1/5=20%

Event 3- Spinner B lands on a black or purple slice.

8 black or purple slices, 8 total slices

8/8=1=100%

Event 4- Spinner A lands on a green slice.

0 green slices, 15 total slices

0/15=0=0%

So, in order of least to most likely, we have Event 4 (0%), Event 2 (20%), Event 1 (25%), and event 3 (100%).

Solve for x:

4x + 8 = 5x + 2

Answers

Answer: X = 6

Step-by-step explanation:

4x + 8 = 5x + 2

-5x -5x (minus 5x from each side)

-x+8=2

-8 from each side

-x = -6

divided by -1 from each side

x = 6

X=6

First thing you want to do it separate the x and the numbers on different sides by subtracting or adding.
4x+8 = 5x +2
-4x. -4x

8=x+2
-2. -2
6=x

How many different simple random samples of size 5 can be obtained from a population whose size is 51? The number of simple random samples which can be obtained is 281887200281887200. (Type a whole number.)

Answers

Answer:

2349060

Step-by-step explanation:

Given that :

Population size (n)= 51

Number of simple random samples (r) = 5

Using the combination formula :

nCr = n! ÷ (n-r)! r!

51C5 = 51! ÷ (51 - 5)!5!

51C5 = 51! ÷ 46!5!

51C5 = (51*50*49*48*47)*46! / 46! * (5*4*3*2*1)

51C5 = (51*50*49*48*47) / (5*4*3*2*1)

51C5 = 281887200 / 120

= 2349060

a map of barn is shown in coordinate plane in which the coordinates are measured in yards. The map shows the barn a (4,6). A well is dug at (4, y). What are the two values of y such that the barn is 70 yards from the well

Answers

Answer:

The values of y such that the barn is 70 yards from the well are y=76 or y=-64

Step-by-step explanation:

Distance in the Plane

Given two points in a rectangular system of coordinates (a,b) and (c,d) the distance measured between them is calculated with the formula

$d=√((c-a)^2+(d-b)^2)$

The barn is located at (4,6) and the well is located at (4,y). The value of y must be calculated in such a way the distance between the barn and the well is 70 yards. Thus, the equation to solve is

$70=√((4-4)^2+(y-6)^2)$
