Answer:
125.6637061 or 125.7
Step-by-step explanation:
V=πr²h
Big: π(3)²(5) = 141.3716694
Hole: π(1)²(5) = 15.70796327
141.3716694
- <u>15.70796327</u>
125.6637061
Answer:
Y = - 2/3 x + 3
Step-by-step explanation:
y = -2/3x+5/3
Slope = -2/3. .. parallel line has same slope
For (- 3 , 5)
Y intercept = y - my = 5 - ( (-2/3) x (-3) ) = 3
Y = slope x X + y intercept
Y = - 2/3 x + 3
Answer: B
Work:
-5x+10>-15 = x<3/10
Let's begin by listing out the information given to us:
There are four students: n = 4
Number of students to be selected: r = 2
To calculate the combination of 2 students to be chosen, we use:

Therefore, there 12 possible combinations from these
Answer:
P(black) = 2/3
Step-by-step explanation:
We need to find the total number of marbles
2 red marbles+ 3 white marbles+ 10 black marbles = 15 marbles
To find the probability that Sam chose a black marble, we take the number of black marbles and divide by the total number of marbles
P(black) = black marbles/total marbles
= 10/15
Divide the top and bottom by 5
= 2/3
