A drawer contains black socks and white socks. 40% of the socks are black socks. A number generator simulates randomly selecting

10 socks from the drawer. The number generator is used 10 times and the number of black socks in each trial is shown in the dot plot.
Which description is correct about the number generator being fair or not?




a)The number generator is not fair. It picked black socks half of the time.

b)The number generator is not fair. In three experiments, it picked black socks 50% of the time.

c)The number generator is fair. It picked the approximate percentage of black socks most of the time.

d)The number generator is fair. It picked black socks half of the time.

[(7+3)x5-4](divided by) 2+3<br> SHOW ALL WORK WILL MARK BRAINLIEST
Nesterboy [21]

Answer:

26

Step-by-step explanation:

[(7+3)5-4]/2+3

-To solve this equation you have to use PEMDAS

P- Parentheses

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction-

- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])

Step 1) [(10)5-4]/2+3

- First you do "P," parentheses, so you add 7+3=10

Step 2) [50-4]/2+3

- Next you do "M," multiplication, and multiply 10x5=50

Step 3) [46]/2+3

- Then you do "S," subtraction, and subtract 50-4=46

(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)

Step 4) 23+3

- Now we do "D," division, and divide 46/2=23

Step 5) 23+3=6

- Finally we do "A," addition, and add 23+3=26 so the answer is 26

(FYI: "/" means division)

Given: ∆AKL, AK = 9, m∠K = 90°, m∠A = 60°. <br>Find: The perimeter of ∆AKL, The area of ∆AKL.
Brut [27]
Perimeter = 27 + 9*sqrt(3), Approximately 42.58845727 
Area = 40.5*sqrt(3). Approximately 70.14805771  
Since all triangles have a total of 180 degrees and we've been given 2 of those angles, the remaining angle is 180 - 90 - 60 = 30 degrees. So we have a 30,60,90 degree right triangle. Drawing the triangle and assigning the proper angle to each vertex shows that AK is the short leg of the triangle. And since it's a 30,60,90 triangle, the hypotenuse is AL and it will be twice the length of AK, so it's 18. And finally, we can use the Pythagorean theorem to calculate the length of KL. So 
KL = sqrt(18^2 - 9^2) = sqrt(324 - 81) = sqrt(243) = sqrt(81*3) = 9*sqrt(3) 
 So the perimeter is 
P = 9 + 18 + 9*sqrt(3) = 27 + 9*sqrt(3). Which is approximately 42.58845727 
 The area is base times height divided by 2. And we have a base of 9 and a height of 9*sqrt(3). So
 A = 9 * 9*sqrt(3)/2 = 81*sqrt(3)/2 = 40.5*sqrt(3). Which is approximately 70.14805771

What is the gradient of the blue line
alexandr402 [8]

The gradient is also known as the slope and we can find it using the slope/gradient formula: (y2 - y1) / (x2 - x1)

To find the gradient/slope, we need to first choose two points on the line. You can choose any two points you like, as long as they are on the line you are trying to find the slope of.

Point 1 = (2,2)

Point 2 = (5,8)

Now, we can plug in these points to the formula and solve.

(8 - 2) / (5 - 2)

6 / 3

2

The gradient of the blue line is 2.

Hope this helps!! :)
