Assuming that the selection process was done without replacement, the probability of selecting two white mugs without replacement is 1/28
<h2>Given data</h2>
Sample Space
Red mugs = 4
yellow mugs = 8
white mugs = 2
Sample Size = 4+8+2 = 14
We are going to assume the selection was done with out replacement
Hence the probability of selecting the first white mug is
<em>Pr(W1) = 2/8 = 1/4</em>
<em>The probability of selecting the second white mug is </em>
<em>Pr(W2) = 1/7</em>
<em />
Hence the probability of selecting two white mugs one after another
= 1/4*1/7
=1/28

Answer:
Explanation:
In this case, you need to solve for y in y + y/a = b, if s ≠ - 1.
This is how you do it step-by-step:
<u>1. Multiply all the equation by the common denominator</u>: a
<u>2. Simplify</u>:
<u>3. Common factor:</u> y
<u>4. Divide both sides by a + 1</u>
Answer:
y= 3x +11
Step-by-step explanation:
<u>slope-intercept form:</u>
y= mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is 3, m=3
substitute m=3 into the equation:
y= 3x +c
To find the value of c, substitute a coordinate.
When x= -3, y=2,
2= 3(-3) +c
c -9= 2
c= 9 +2 <em>(</em><em>+</em><em>9</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
c= 11 <em>(</em><em>s</em><em>implify</em><em>)</em>
Thus, the equation of the line is y= 3x +11.
Answer:
1. C
2.A
3.A
4.B
Step-by-step explanation:
First, lets start by getting all of the perimeters and volumes of the pools. For pool A, it has a volume of 18*9.75*4.5=789.75 cubic feet, and a perimeter of 18*2+9.75*2=55.5 feet. For pool B, it has a volume of 16*10*5=800 cubic feet, and a perimeter of 16*2+10*2=52 feet. For pool C, it has a volume of 15*12*4.5=810 cubic feet, and a perimeter of 15*2+12*2=54 feet. Therefore, for problems 1 and 2, Model C needs the largest amount of water to be filled, while model A needs the least. For problems 3 and 4, Model A uses the largest liner, while Model B uses the smallest one. Hope this helps!
Answer:
b
Step-by-step explanation:
its b because you add the 3.4n +2.5n then you subtract -5.3+2.8
