A quality-control center finds that 2 out of 250 toy trains are defective. How many trains would they expect to be defective in

solmaris [256]

Its A. 10,000 divided by 250 is 40. Then multiply 40 by 2 and you get 80

10,000 / 250 = 40
40 * 2 = 80
80= A.

Four dice, each numbered in the usual way from 1 to 6, are colored white, red, green and blue respectively. After casting them a

Delvig [45]

Suppose that the numbers that the boy being cast from the dice are 3 4 5 6.
3 stands for white, 4 stands for red, 5 stands for green and 6 stands for blue.
We need to interpret the statement given above. The set of numbers is 3 4 4 6 6 5.
First, we need to get the mean of this set. Add all the numbers and divide by the total number that the set has.
3+4+4+6+6+5= 28 / 6
= 4.67 The mean is 4.67
For the variance, we will use the mean above ( 4.67 )

1. Squared the mean and subtract how many numbers are present in the set.
4.67x4.67= 21.8089 /6 = 3.64 set aside this result
2. Next squared all the numbers present in the set and add the result

3x3= 9 , 4x4= 16, 4x4=16, 6x6=36, 6x6=36, 5x5=25

9+16+16+36+36+25= 138

3. Subtract the result of #2 with #1
138 - 3.64= 134.36 set this aside

4. Subtract 1 from the total numbers you have in your set

6 - 1= 5

5. Divide the result we have in #3 with the result of #4

134.36 / 5= 26. 872

So the variance is 26.872

Find the common denominator 2/7 and 7/10

deff fn [24]

Answer:

Step-by-step explanation:

Finding the common denominator is really just finding the gcf of 7 and 10. The gcf of 7 and 10 is 70. So the common denominator is 70.

What are the solutions of |x+6| greater than or equal to 5? Write the solutions as either the union or the intersection of two s

sukhopar [10]

We have that
 |x+6| >= 5
step 1
resolve for (x+6)>=5------> x>=5-6-------> x>= -1
the solution is the interval (-1, ∞)

step 2
resolve for -(x+6) >=5------> -x-6 >=5----> -x >= 5+6---> -x>=11----> x<=-11
the solution is the interval (-∞, -11)

using a graph tool
see the attached figure

the solution is the interval (-∞, -11) ∩ (-1, ∞)
