Answer:

8

Step-by-step explanation:

Here is the full question :

n a managed forest, three different trees are planted. The trees are beech, holly and maple.

For every beech tree planted, there are 2 holly trees planted and 5 maple trees planted.

(a) Write down the ratio of trees.

b) If 40 maple trees were planted, how many beech trees would be planted? ​

the ratio of beech to holly to maple = 1 : 2 : 5

number of maple trees planted =( ratio of maple trees / sum of ratios ) x total number of trees

sum of ratios = 1 + 2 + 5 = 8

let a = total number of trees planted

( 5/8 ) x a = 40

a = 64

total number of beech planted = (1 / 8 ) x 64 = 8

Suppose that a box contains 8 cameras and that 4 of them are defective. A sample of 2 cameras is selected at random. Define the
maria [59]

Answer:

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2

Step-by-step explanation:

Given that:

Total Number of cameras (n) = 8

Defective cameras = 4

X: number of defective cameras

For a binomial distribution :

P(x) = nCx * p^x * (1 - p)^(n - x)

Probability of success (p) on each trial is the same = (total number of samples / number of defective samples) = 8/4 = 0.5

If 2 samples are chosen at random :

Then, the binomial probability distribution will be :

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2

Question is attached, please explain a little:) will mark BRAINLIEST
Alexus [3.1K]

Answer:

D

Step-by-step explanation:

We know it has 2 distinct zeros. This means the discriminant of the quadratic is positive and must have 2 real zeros that can be rational or irrational. We also know the quadratic has rational coefficients which means both are either rational or irrational. They can not be one of either. Since it tells us one is rational, the other must be too.

Ket [755]

Answer:

\frac{1}{12}

Step-by-step explanation:

\frac{(\sqrt{4} + 3)2 - 9}{ (\sqrt{9} - 1)3 * 2}=\frac{(2+3)2-9}{(3-1)6}=\frac{10-9}{2*6}=\frac{1}{12}
