There are 5 pens total; 3 of them red.
first draw probability red: 3/5
second draw probability red: 2/4
On the second draw there is one less red pen and one less total pens because they are not being put back into the pool of pens.
combined probability red then red (without replacement)
= (3/5) * (2/4) = 6/20 = 3/10
You can do this by cross multiplying
Answer:
A) 3, B) 8 and 4, C) 12
Step-by-step explanation:
There are 3 terms: 8x^2, 4x, and 12.
The coefficiemts are numbers that come before a variable. That's why the coefficients are 8 and 4.
The constant is the number that doesn't come with a variable, thus 12.
Answer:
2.25
Step-by-step explanation:
The old width of 4 inches became a new width of 9 inches.
Old: 4 in.
New 9 in.
The old length of 6 inches became a new length of 13.5 inches.
Divide the new size by the corresponding old size.
9/4 = 2.25
13.5/6 = 2.25
You see in both cases, the scale factor is 2.25
The scale factor is 2.25
