Suppose you and a friend each choose at random an integer between 1 and 8, inclusive. For example, some possibilities are (3,7),

Answer and explanation:

Given : Suppose you and a friend each choose at random an integer between 1 and 8, inclusive.

The sample space is

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (1,7) (1,8)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (2,7) (2,8)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6) (3,7) (3,8)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (4,7) (4,8)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6) (5,7) (5,8)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6) (6,7) (6,8)

(7,1) (7,2) (7,3) (7,4) (7,5) (7,6) (7,7) (7,8)

(8,1) (8,2) (8,3) (8,4) (8,5) (8,6) (8,7) (8,8)

Total number of outcome = 64

To find : The following probabilities ?

Solution :

The probability is given by,

$\text{Probability}=\frac{\text{Favorable outcome }}{\text{Total outcome}}$

a) p(you pick 5 and your friend picks 8)

The favorable outcome is (5,8)= 1

$\text{Probability}=\frac{1}{64}$

b) p(sum of the two numbers picked is < 4)

The favorable outcome is (1,1), (1,2), (2,1)= 3

$\text{Probability}=\frac{3}{64}$

c) p(both numbers match)

The favorable outcome is (1,1), (2,2), (3,3), (4,4), (5,5), (6,6), (7,7), (8,8) = 8

$\text{Probability}=\frac{8}{64}$

$\text{Probability}=\frac{1}{8}$

Answer:

Plot the points in black and connect them.

Plot the point in blue and count up 3 and to the right 1. Plot and connect the points.

Step-by-step explanation:

Using your cursor/mouse, you will first choose the color black. Then you will plot the points given to you (2,2) and (5,8) by first finding the x-coordinate of (x,y). Start at 2 on the x-axis. Follow the grid line up two units so you will also be at the 2 on the y-axis. Plot or draw a dot/circle on this grid line. Go back to the x-axis and start again at 5 on the x-axis. Follow the grid line up eight units so you will also be at the 8 on the y-axis. Plot or draw a dot/circle on this grid line. Connect the dots for your line.

Using your cursor/mouse, you will choose the color blue. Then you will plot the point given to you (10,5) by first finding the x-coordinate of (x,y). Start at 10 on the x-axis. Follow the grid line up five units so you will also be at the 5 on the y-axis. Plot or draw a dot/circle on this grid line. Instead of plotting another point. This time you will count from the blue point up three units and over to the right one. Mark this grid line as a point. Now connect them.

The opposite of -10 is 1.-(-(-10)) 2.-10 3.10 4.-|10|

Is this answer right?? If not what’s the real answer? I’m trying to practice for my STAAR.

Area of rectangle

21m^2

Area of one triangle

divide length of 7 by 2 (3.5)

gives you length b (unknown side that is not hypotenuse)

then multiply by width of triangle (4)

3.5 * 4 = 14

and in this situation there is no need to divide by two, because you essentially have one full square from both the triangles. this only works when both triangles are the same.

add the area of the rectangle

14+21= 35

A construction company delivered 40 loads of concrete in 5 days.

AnnZ [28]

Well 40 divided by 5 is 8 and you don't have options so I would say 8 loads a day :)
