That is a isosceles triangle, therefore x and the top angle are the same.

There’s 180 degrees in a triangle.

Therefore:

(180 - 38)/2 = x
142/2 = x
71 = x

We can Notice that : Number of Cells growth is a Geometric Sequence

That is : 1 , 2 , 4 , 8 , 16. . . . .

We know that : nth term in a Geometric Sequence is = a.rⁿ⁻¹

where a is the first term

r is the common ratio, which is given by ratio of 2nd term to 1st term

For the above Sequence, a = 1 and r = 2

Given : nth term over 1000

⇒ 1.2ⁿ⁻¹ = 1024

⇒ 2ⁿ⁻¹ = 2¹⁰

⇒ n - 1 = 10

⇒ n = 11

We can Notice that : Number of Hours is a Arithmetic Sequence

That is : 0 , 3 , 6 , 9 , 12

We know that : nth term in a Arithmetic Sequence is = a + (n - 1)d

where a is the first term

r is the common difference, which is given by difference between 2nd term and 1st term

For the above Sequence, a = 0 and r = 3 - 0 = 3

we need to find the number of hours, which is when : n = 11

⇒ 0 + (11 - 1)3

⇒ 10(3)

⇒ 30

⇒ It will take 30 hours to have over 1000 bacteria

Solve the system of equations using substitution. y = −2x + 1 4x + 2y = −2

Brums [2.3K]

Answer:

No solution

Step-by-step explanation:

The first equation is $y=-2x+1$

The second equation is $4x+2y=-2$ .

Put the first equation into the second one.

$4x+2(-2x+1)=-2$ .

$4x-4x+2=-2$ .

$4x-4x=-2-2$ .

$0=-4$ .

This is not TRUE.

Therefore the system has no solution

Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semest

sineoko [7]

Answer:

0.91824 = 91.824% probability that more than 3 students will have their automobiles stolen during the current semester.

Step-by-step explanation:

We have only the mean, which means that the Poisson distribution is used to solve this question.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semester.

This means that $\mu = 7$

What is the probability that more than 3 students will have their automobiles stolen during the current semester?

This is:

$P(X > 3) = 1 - P(X \leq 3)$

In which

$P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)$

So

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-7}*7^{0}}{(0)!} = 0.00091$

$P(X = 1) = \frac{e^{-7}*7^{1}}{(1)!} = 0.00638$

$P(X = 2) = \frac{e^{-7}*7^{2}}{(2)!} = 0.02234$

$P(X = 3) = \frac{e^{-7}*7^{3}}{(3)!} = 0.05213$

Then

$P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.00091 + 0.00638 + 0.02234 + 0.05213 = 0.08176
$

$P(X > 3) = 1 - P(X \leq 3) = 1 - 0.08176 = 0.91824$

0.91824 = 91.824% probability that more than 3 students will have their automobiles stolen during the current semester.
