the formula for volume of sphere is 4/3||r^3
diameter=2radius
in the formula we need to have radius but we have been given diameter so we convert diameter to radius
d=2r
r=d/2
9.5÷2
4.75
x^2*(-3x)=-3x^3. The power of x becomes 3 because you add the powers of x. (2+1=3)
Answer:
The probability of picking two consecutive purple marbles without replacement is 14.72%.
Step-by-step explanation:
Initially, there are 4+6+2+8 = 20 total marbles.
The probability of picking a purble marble is
P_{1} = \frac{number of purple marbles}{number of total marbles}
P_{1}= \frac{8}{20} = 0.4
Since there are no replacements, there are now 19 total marbles, 7 of which are purple. So, the probability of picking another purple marble is
P_{2} = \frac{7}{19} = 0.368
The probability P of picking a purble marble(P_{1}), not replacing it, and then picking another purple marble(P_{2}) is:
P = P_{1}*P_{2} = 0.4*0.368 = 0.1472 = 14.72%
Answer:
B. 2 is your answer
Step-by-step explanation:
You will use the slope formula to find the slope of the equation.
(3, 7) and (-2, -3) will be used.
7 and -3 are your y's. 3 and -2 are your x's.
(7 - (-3))/(3 - (-2)) = 10/5 = 2
