Answer:
2.38%
Step-by-step explanation:
Given that:
The population size involving numbers of treated and untreated seeds N = 10
the number of seeds that are treated which are observed = 5
the number of seeds that sprouted 'n' = 4
Now, use the method of hypergeometric probability, we have the formula:
∴
p(4) = 0.0238
p(4) = 2.38%
Answer: 38 is not a perfect square.
square root of 38 is 6.164
Step-by-step explanation:
it is between 6 and 7
Answer:
81 units
Step-by-step explanation:
Given data
We are given the function for the height, the height is a function of time t
h=-16t^2+75t
Hence for t= 3 , let us substitute and find the height h
h=-16(3)^2+75(3)
h= -16*9+ 225
h= -144+ 225
h= 81
Hence the height at 3 seconds is 81 units
First you multiply 5 to both sides to get x by itself so now it is -15=x and now it is solved
Since Suzy has 2 pens, Maurice would have 4. Then since Maurice has four pens Alice has seven times more than he does so 4•7=28. When you combine Suzy’s and Alice’s pens that gives us 30 but Paul has 2/3 of their pens so that would be 20. Since Paul has 20, Dawn has a dozen (12) more then he does so Dawn has 32 pens in total.
