Answer:
Answer is 49
Step-by-step explanation:
Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147
(21 3/4) / (2 1/2) =
(87/4) / (5/2) =
87/4 * 2/5 =
174/20 reduces to 8 7/10 (or 8.7)meters per hr
The slopes of parallel lines are exactly the same.
Answer:
Standard deviation = 0.547
Step-by-step explanation:
Given the data
$5 for spade
$10 for any club
$20 for an ace club
Lets assume Probability of getting these cards to be
0.5, 0.20 and 0.30
Therefore, mean would be
Summation (PX) = 5×0.5 + 10×0.2 +20×0.3
Summation (PX)/n= 10.5/35 = 0.3
Standard deviation = √0.3
Standard deviation = 0.547
Answer:
6*x^(2/5)*y^(1/5)
Step-by-step explanation:
The fifth root of x^2 is x^(2/5).
That of y is y^(1/5).
Then the given expression, rewritten with fractional exponents, is
6*x^(2/5)*y^(1/5)
