Answer:

\(4\frac{8}9}\)

Step-by-step explanation:

We can do this mathematically.

\(5-\frac{2}{18} = \frac{90}{18} - \frac{2}{18} = \frac{88}{18} = \frac{44}{9} = 4\frac{8}{9} \\\)

We can also work this logically.

We know that \(\frac{2}{18}\) is less than 1, so our answer should be (5-1) and a fraction.

Our answer should be 4 plus a fraction less than 1. To find what we need to add to \(\frac{2}{18}\) to make 1, we ask ourself how many eighteenths make 1. So if we need to 18 parts and we have 2 already, we add 16 eighteens to make 1. The answer is \(4 \frac{16}{18}\), or simplified, \(4\frac{8}9}\).

Answer:

Converse of the Alternate Exterior Angles Theorem.

Step-by-step explanation:

The alternate exterior angles theorem explains that "if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent." Judging from the fact that the problem is including <1 and <8, we can safely assume that it is including this theorem since both of said angles are on the exteriors of the pair of parallel lines. Not to mention that this principle also effectively proves that both lines are parallel to each other, thus proving this sentence true.

The observed proportion of correct diagnoses in a random sample of mechanics is not necessarily the same as the MLE, as the MLE involves a more formal estimation procedure that considers the underlying probability distribution and maximizes the likelihood function based on the observed data.

The Maximum Likelihood Estimation (MLE) and the observed proportion of correct diagnoses in a random sample of mechanics are related concepts but not the same.

The MLE is a statistical method used to estimate the parameters of a probability distribution based on observed data. It seeks to find the parameter values that maximize the likelihood of observing the given data. In the case of a binomial distribution, which could be used to model the number of correct diagnoses, the parameter of interest is the probability of success (correct diagnosis) for each trial (mechanic).

In this context, if we have a random sample of 20 mechanics and observe that 15 of them made correct diagnoses, we can calculate the observed proportion of correct diagnoses as 15/20 = 0.75.

While the observed proportion can be considered an estimate of the underlying probability of success, it is not necessarily the same as the MLE. The MLE would involve maximizing the likelihood function, taking into account the specific assumptions and model chosen to represent the data. The MLE estimate may or may not coincide with the observed proportion, depending on the distributional assumptions and the specific form of the likelihood function.

In summary, the observed proportion of correct diagnoses in a random sample of mechanics is not necessarily the same as the MLE, as the MLE involves a more formal estimation procedure that considers the underlying probability distribution and maximizes the likelihood function based on the observed data.

If they charges a one-time fee of $45, plus $25 per hour, then the the slope of this situation is $25 per hour.

The situation described can be represented by the linear equation

Cost = $45 + $25 × hours

where "Cost" is the total cost of the tour and "hours" is the number of hours for which the tour is taken.

The slope of this equation represents the rate of change in the cost of the tour with respect to the number of hours.

In other words, it tells us how much the cost increases for each additional hour of the tour.

The slope of this equation is simply the coefficient of the "hours" variable, which is $25.

Answer:

y = -1/14x + 109/14

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = 14x + 12. Its slope is 14. A line perpendicular to this one will have a slope of -1/14.

Plug this value (-1/14) into your standard point-slope equation of y = mx + b.

y = -1/14x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-3, 8). Plug in the x and y values into the x and y of the standard equation.

8 = -1/14(-3) + b

To find b, multiply the slope and the input of x (-3)

8 = 3/14 + b

Now, subtract 3/14 from both sides to isolate b.

8 - 3/14 = b

112/14 - 3/14 = b

109/14 = b

Plug this into your standard equation.

y = -1/14x + 109/14

This equation is parallel/perpendicular to your given equation (y = 14x + 12) and contains point (-3, 8)

Answer:

15.15% probability that Neil selects a bone and then a ball

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Initially, there are 3+4+5 = 12 treats. 4 of those are bones. So the probability of selecting a bone is 4/12 = 1/3.

Now suppose a bone has been selected. Now there are 11 treats, 5 of which are balls. So the probability of selecting a ball in this situation is 5/11.

What is the probability Neil selects a bone and then a ball?

\(p = \frac{1}{3}*\frac{5}{11} = \frac{5}{33} = 0.1515\)

The amount distributed per person and number of person can be found out by using the concept of square numbers

A "square" is the product of an integer or number (not a fraction) multiplied by itself.

The amount collected by charity Rs 15700

It is to be distributed such a way that number of people and amount distributed per person is same.

Let this number be 'a'

The number of person× amount distributed per person=total money collected

a×a=15700

Taking square root on both sides

\(a^{2} =15700\\\)

\(a=\sqrt{15000}\)

\(a=\pm125.299\)

-125.299 is neglected as number of people cannot be negative

Hence, a=125.299

The number of people and amount per person is 125 since number of people cannot in decimal.

So the possible amount for distribution in total

=125*125

=15625

The amount left undistributed

= total amount collected for the event-possible amount for distribution

=15700-15625

=75

Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.

Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.

The total amount of paint needed is 3 gallons, so we have the equation:

x + y = 3

The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:

(80/100)x + (30/100)y = (50/100)(x + y)

Simplifying this equation, we get:

0.8x + 0.3y = 0.5(x + y)

Now, we can solve this system of equations to find the values of x and y.

Let's multiply both sides of the first equation by 0.3 to eliminate decimals:

0.3x + 0.3y = 0.3(3)

0.3x + 0.3y = 0.9

Now we can subtract the second equation from this equation:

(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)

-0.5x = 0.9 - 0.5x - 0.5y

Simplifying further, we have:

-0.5x = 0.9 - 0.5x - 0.5y

Now, rearrange the equation to isolate y:

0.5x - 0.5y = 0.9 - 0.5x

Next, divide through by -0.5:

x - y = -1.8 + x

Canceling out the x terms, we get:

-y = -1.8

Finally, solve for y:

y = 1.8

Substitute this value of y back into the first equation to solve for x:

x + 1.8 = 3

x = 3 - 1.8

x = 1.2

Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.
