Given:
Total number of book = 22
Number of white books = 6
Number of Purple books = 9
Number of green books = 7
To find:
The probability that Warren takes out a green book in both draws (with replacement).
Solution:
We know that,
After replacement, the probability of event remains the same and the independent.
The probability that Warren takes out a green book in both draws is:
Therefore, the correct option is (a).
9514 1404 393
Answer:
Step-by-step explanation:
1 m is 100 cm, so the volume is ...
V = LWH
V = (100 cm)(50 cm)(4 cm) = 20,000 cm³ . . . volume
__
The mass is ...
(20,000 cm³)(2.7 g/cm³) = 54,000 g = 54 kg
The mass of the block is 54 kg.
The simpliest form is 71/10, the fraction
Step-by-step explanation:
Since this isn't a really small (1/1000000000) or really big (like the radius of the earth) number you don't need the standard notation, so the fraction 71/10 is the simpliest because there is only a decimal, so it can be a fraction of ten.
Given:
AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.
To find:
The 
and 
.
Solution:
AD is diameter of the circle. So, the measure of arc AD is 180 degrees.
The measure inscribed angle is half of the corresponding subtended arc.
AB is the tangent. So, 
because radius is perpendicular on the tangent and the point of tangency.
Therefore, 
and .
Answer:
$32.18
Step-by-step explanation:
It's really just addition. No explanation necessary.
