Probability that a pen from the first box and a crayon from the second box are selected is 1/5.
<u>Step-by-step explanation</u>:
Step 1 :
- First box contain = 1 pencil + 4 pens = 5 items
- Second box contain = 6 color pencils + 2 crayons = 8 items
Step 2 :
Probability for a pen from 1st box, P(pen) = no. of pens / total items
P(pen) = 4/5
Probability for a crayon from 2nd box, P(crayon) = no. of crayons / total items
P(crayon) = 2/8 = 1/4
Step 3 :
P(pen) and P(crayon) = (4/5) 
(1/4)
= 4/20
P(pen) and P(crayon) = 1/5
Answer:
A 95% confidence interval for a population mean is computed from a sample of size 400. Another 95% confidence interval will be computed from a sample of size 100 drawn from the same population. Choose the best answer to fill in the blank: The interval from the sample of size 400 will be approximately _______as the interval from the sample of size 100.
<span>A) y=-2x+19
B) y=x+7
Multiplying B) by -1
B) -y = -x -7 then adding it to A)
A) y = -2x + 19
3x = 12
x = 4
y = 11

Answer:
Start at the origin and plot the points.
Step-by-step explanation:
For A, start at the origin and then go 4 units to the left.
For B, start at the origin and then go 4 units up.
For D, start at the origin and then go 4 units to the right.
For C, start at the origin and then go 4 units down.
