Answer:

0.0882

Step-by-step explanation:

Given that:

Mean(m) = 281

Standard deviation (s) = 33

Probability of weight between 291 and 299 gram

Obtain the standardized score (Zscore):

P (X ≤ 291)

Zscore = (x - m) / s

Zscore = (291 - 281) / 33

Zscore = 10 / 33 = 0.303

P(Z ≤ 0.303) = 0.61906 (Z probability calculator)

P (X ≤ 299)

Zscore = (x - m) / s

Zscore = (299 - 281) / 33

Zscore = 18 / 33 = 0.5454

P(Z ≤ 0.5454) = 0.70726 (Z probability calculator)

Hence, probability of weight between 291 and 299 gram = 0.70726 - 0.61906 = 0.0882

1. x =3

Because you have 3 little squares for one x

2. x= -12

Answer:

1. A.3

2. B.

Step-by-step explanation:

B 1/2=.5

Answer:

D or 1-(17/29)^4

Step-by-step explanation:

This is because you need to figure out the probability that a selected marble is not blue, which is (17/29)^4. Then you can calculate the probability that one of them is blue by taking this number, and subtracting it from 1. This results in 1-(17/29)^4.

The probability that at least 1 of the selected marbles is blue is  1 - ([tex]\frac{17}{29}[/tex])⁴.

Probability in simple terms is the chance of getting an event. Probability of any event can be found by number of likely outcomes divided by the total number of outcomes.

Probability with replacement means the events are independent. That is, the probability of first event does not depend on the second event.

For two independent events A and B,

P(A and B) = P(A) × P(B)

In the question,

Number of red marbles = 11

Number of blue marbles = 12

Number of white marbles = 6

Total number of marbles = 29

Four marbles are selected with each marble being replaced after each selection.

We have to find the probability that at least 1 of the selected marbles is blue. For that, first we find the probability of no marbles are blue.

P(no marbles are blue) = P(red marbles or white marbles)

                                      = Number of red and white marbles / total number                      

                                         of marbles

                                      = (11 + 6) / 29 = 17/29

P(no marbles are blue) for four takes =  [tex]\frac{17}{29}[/tex] ×  [tex]\frac{17}{29}[/tex] ×  [tex]\frac{17}{29}[/tex] ×  [tex]\frac{17}{29}[/tex]

                                                              =  ([tex]\frac{17}{29}[/tex])⁴

Total probability of a sample space is always 1.

So, the probability that at least 1 marble is blue = 1 -  ([tex]\frac{17}{29}[/tex])⁴.

Hence the probability that at least 1 of the selected marbles is blue is  1 - ([tex]\frac{17}{29}[/tex])⁴.

Answer:

Half life = 4.7 days

Step-by-step explanation:

Formula to get the final amount of the substance after the time 't',

[tex]N_t=N_0e^{-kt}[/tex]

Here, [tex]N_t[/tex] = Final amount of the substance

[tex]N_0[/tex] = Initial amount

k = decay constant

t = Duration or time

Now by substituting the values in the formula,

[tex]N_t=N_0e^{-0.1473t}[/tex]

If [tex]N_t=\frac{1}{2}(N_0)[/tex] [For half life]

[tex]\frac{1}{2}(N_0)=N_0e^{-0.1473t}[/tex]

[tex]\frac{1}{2}=e^{-0.1473t}[/tex]

[tex]2=e^{0.1473t}[/tex]

ln(2) = [tex]\text{ln}(e^{0.1473t})[/tex]

0.69315 = 0.1473t

t = 4.71 days

t ≈ 4.7 days

Therefore, half life of the substance is 4.7 days.

Answer:

x=5

Step-by-step explanation:

-5x+6(5x-18)=17

-5x+30x-108=17

25x-108=17

25x=17+108

25x=125

x=5

We are given:

Probability of passing = p

Probability of Failing = 6p²

__________________________________________________________

Finding the value of 'p':

We know that the sum of the probabilities of an event occurring and not occurring is 1

So, Probability of passing + Probability of Failing = 1

p + 6p² = 1

6p² + p - 1 = 0

We can see that we now have a quadratic equation

Splitting the middle term:

6p² + 3p - 2p - 1 = 0

3p(2p + 1) - (2p + 1) = 0

(3p - 1)(2p + 1) = 0                      [factoring out 2p + 1]

Now, we can either divide both sides by (3p-1) or by (2p + 1) and both the cases will give us different answers.

Dividing both sides by (3p - 1):

2p + 1 = 0/(3p-1)

2p + 1 = 0

p = -1/2

Dividing both sides by (2p+1):

(3p - 1) = 0 / (2p + 1)

3p - 1 = 0

p = 1/3

Now, we have 2 values of p: -1/2 and 1/3

Using the value: -1/2 will mean that the probabilities are negative

but we know that probabilities cannot be negative.

So, -1/2 is not a valid value for p

Therefore, the value of p is 1/3

Answer:

10y x 6x = y = sitting fee x = $6

Step-by-step explanation:

The function is y = 10 + 6x, where y represents the total charge and x represents the number of sheets.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

Let's suppose the total charge is y and the number of the sheets is x.

So according to the problem:

y = 10 + 6x

Here y represents the total charge and x represents the number of sheets.

Thus, the function is y = 10 + 6x, where y represents the total charge and x represents the number of sheets.
