Suppose that the probability a seed will germinate is 85%. What is the probability that 7 of these seeds will germinate when 10

Neporo4naja [7]

Answer: The probability that 7 of these seeds will germinate when 10 are planted is 0.1298 .

Step-by-step explanation:

Let x be the number of seeds germinate .

Since each seed is independent from other , so we can use binomial over here.

Binomial probability formula : $P(X=x)=^nC_xp^x(1-p)^{n-x}$ , where n= total trails and p is the probability of each success.

As per given : p= 0.85 , n= 10

Then, the probability that 7 of these seeds will germinate when 10 are planted will be :-

$P(X=7)=^{10}C_7(0.85)^7(1-0.85)^3\\\\=\dfrac{10!}{7!3!}(0.85)^7(0.15)^3\\\\=0.129833720754\approx0.1298$

Hence, the probability that 7 of these seeds will germinate when 10 are planted is 0.1298 .

B<br> 8<br> 7<br> Find the length of "e" to the<br> nearest tenth using the<br> Pythagorean Theorem.

Juliette [100K]

Answer:

≈ 10.63

Step-by-step explanation:

Pythagorean Theorem... Possibly the most easy theory in math once you understood it.

Here's the formula.

$A^2+B^2=C^2$

AB would be the hypothenuse

BC would be the opposite

CA would be the Adjacent.

But let's not make it complicated though, the question is actually quite easy.

You are asked to find AB, the hypothenuse.

The hypothenuse would be C.

BC and CA would be A and B.

It doesn't matter where are you going to place the numbers.

So, $7^2 + 8^2$

$7^2 + 8^2 = 49 + 64\\$

= 113

Now we would have to square root 113 since $A^2+B^2=C^2$

$\sqrt{113}$ is an irrational number, and the question asks you to round ro the nearest tenth.

$\sqrt{113}$ =10.63014581

≈ 10.63

Your answer would be 10.63
