<span>One side of a triangle is half the longest side. The third side is 8 m less than the longest side
Let x,x/2 and (x-8m) represent these sides
</span>

x + x/2 + (x-8m) = 42m
Solving for x
5/2x = 50m
x = 20m, the longest side. The other two are 10m and 12m
Three sides are: 10m,12m and 20m

f a seed is planted, it has a 85% chance of growing into a healthy plant. If 9 seeds are planted, what is the probability that e
Vlad1618 [11]

The probability that exactly 1 doesn't grow will be 0.07

<h3> What is Probability?</h3>

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15

Using the Bernoulli approximation:

P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵

P(n=1)=9x0.15¹.⁵x0.8⁸.⁵

P(n=1)=0.07

Hence the probability that exactly 1 doesn't grow will be 0.07

A baseball player has a batting average of 0.25. What is the probability that he has exactly 2 hits in his next 7 at bats
marissa [1.9K]

Answer:

The probability that he has exactly 2 hits in his next 7 at-bats is 0.3115.

Step-by-step explanation:

We are given that a baseball player has a batting average of 0.25 and we have to find the probability that he has exactly 2 hits in his next 7 at-bats.

Let X = <u><em>Number of hits made by a baseball player</em></u>

The above situation can be represented through binomial distribution;

P(X = r) = \binom{n}{r}\times p^{r} \times (1-p)^{n-r}; x = 0,1,2,......

where, n = number of trials (samples) taken = 7 at-bats

            r = number of success = exactly 2 hits

            p = probability of success which in our question is batting average

                   of a baseball player, i.e; p = 0.25

SO, X ~ Binom(n = 7, p = 0.25)

Now, the probability that he has exactly 2 hits in his next 7 at-bats is given by = P(X = 2)

          P(X = 2) =  \binom{7}{2}\times 0.25^{2} \times (1-0.25)^{7-2}

                        =  21 \times 0.25^{2} \times 0.75^{5}

                        =  <u>0.3115</u>
