Using a graphing calculator, we obtain the following regression model.

Thus, the regression model is:

For part b, find the value of x by subtracting 2025 by 2010. Thus, the value of t is 15. Substitute 15 for t in the obtained equation in part a and then solve for P(t).

Thus, there is approximately 41.4 million people on 2025.

For part c, substitute 40 for P(t) in the obtained equation in part a and then solve for t.

Add the obtained value of t to 2010. Thus, the population will reach 40 million in 2020.

Answer:

369

Step-by-step explanation:

g(f(x)) simply means to put the whole expression of function f(x) into the place of "x" in g(x).

and to find the functional value for a specific x we just need to calculate functional value for f(x) and use that result as input for g(x).

f(6) = 8×6 + 5 = 48 + 5 = 53

and now

g(53) = 7×53 - 2 = 371 - 2 = 369

to check we do the general functional substitution :

g(f(x)) = 7×(8x+5) - 2 = 56x + 35 - 2 = 56x + 33

g(f(6)) = 56×6 + 33 = 336 + 33 = 369

Step-by-step explanation:

radius= 4 cm

the area and the diameter of the circle.

\(d = 2r\)

\(d = 2 \times 4\)

\(d = 8 \: cm\)

therefore, the diameter of the circle is 8 centimeters.

\(a = \pi {r}^{2} \)

\(a = \pi \times {4}^{2} \)

\(a = 50.26548 \: {cm}^{2} \)

\(a = 50.27 \: {cm}^{2} \)

hence, the area of the circle is 50.27 square centimeters.

\(diameter = 2r\)

\(d = 2 \times 4\)

\(d = 8 \: cm\)

\(area = \pi {r}^{2} \)

\(a = \pi \times {4}^{2} \)

\(a = 50.26548 \: {cm}^{2} \)

\(a = 50.27 \: {cm}^{2} \: (2 \: d.p)\)

Answer:

4 – 5x = 59, x = -11

Step-by-step explanation:

The given equations is :

4 – 5x = 59

Subtracting 4 both sides,

4 – 5x -4 = 59-4

-5x = 55

Dividing both sides by -5.

x = -11

So, the answer of the given equation is -11.

Answer:

Step-by-step explanation: The first one would be -40 X 30. The parentheses around -25 turns it into a positive. And 5 make you round up

For 2, the -18 turns into a positive 18 bc of the parentheses. So round up to 20. Round 38 up to 40. 20 x 40

For 3, the negative 16 turns positive, making the equation -21 x 9 x 16. Round them to -20, 10, and 20. The equation is -20 x 10 x 20. Hope this helps!

We have a dataset of 5 different engines, each with data on five parameters: Time, Miles, Load, Speed, and Oil. To estimate the time until the first engine overhaul as a function of all four predictor variables, we can use a regression model. To do this, we first create a scatter plot matrix of all possible combinations of features. However, since we only have 5 data points, we cannot say that our model is highly reliable.

It appears that the Time feature is somewhat linearly dependent on the Load feature, so we can use this relationship for the linear regression model:

Time = a*Load + b

We have a scatter plot matrix that we can use to make predictions based on a model, but we should bear in mind that the results may be unreliable due to the limited dataset. To fit a linear regression model to this dataset, we will use the sklearn library in Python. A code snippet is provided for this purpose, in which we import the necessary libraries and load the data into a pandas DataFrame. We then select the "Load" feature as the predictor variable (X) and the "Time" feature as the response variable (y). The linear regression model is then fitted to the data using the LinearRegression() function. The coefficients and intercept of the model are printed as output, which are 0.35 and 1.6019230769230759, respectively.

The slope of 0.35 is not very large, but we can still use it to make predictions for a given value of the "Load" feature. For instance, if we have a load of 23, we can substitute this value in the above model and predict the time for the engine to run before its first overhaul.

Thus, we can predict that the engine will run for 9.25 years until the first engine overhaul, as per the formula:

Time = 0.35*23 + 1.6 = 9.25.

The correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A positive correlation means that as one variable (in this case, happiness) increases, the other variable (GPA) also tends to increase. The magnitude of the correlation coefficient, which ranges from -1 to 1, represents the strength of the relationship. A value of 0.90 indicates a very strong positive linear correlation, suggesting that there is a consistent and significant relationship between happiness and GPA.

This means that as the level of happiness increases among high school students, their GPA tends to be higher as well. The correlation coefficient of 0.90 suggests a high degree of predictability in the relationship between these two variables.

It is important to note that correlation does not imply causation. While a strong positive correlation indicates a relationship between happiness and GPA, it does not necessarily mean that one variable causes the other. Other factors or variables may also influence the relationship between happiness and GPA.

For a standard normal distribution, a negative value of z indicates that the observed value is below the mean of the distribution.

In a standard normal distribution, which has a mean of 0 and a standard deviation of 1, a negative value of z indicates that the observed value is located below the mean. The z-score represents the number of standard deviations a data point is away from the mean.

A negative z-score means that the observed value is lower than the mean, indicating that it falls to the left of the center of the distribution. This means that the data point is relatively lower compared to the average and can provide information about its position within the distribution and its deviation from the mean.

Answer:

Option A

Step-by-step explanation:

Hey there!

From the given figure;

Angle ABE = 90°.

And angle ABD = [(5x+3)° +(3x+7)°]

To find : angle ABC.

Now,

Angle ABD + Angle ABE = 180° [Being linear pair].

or, 90° + [(5x+3)° +(3x+7)°]= 180°

or, (5x+3)° +(3x+7)°= 90°

or, 8x + 10° = 90°

or, 8x = 80°

Therefore, X= 10°.

Now, Angle ABC = (5x + 3)°

= (5*10+3)°

= 53°

Therefore, the measure of angle ABC is 53°.

\(y^3=\frac{x+1}{64}\)

Cube root both sides.

\(y=\frac{\sqrt[3]{x+1}}{4}\)

In a triangle with two interior angles that are both 34 degrees, the third interior angle is 112 degrees.

The measure of the third interior angle of a triangle can be found by subtracting the sum of the two given angles from 180 degrees.

In this case, if two interior angles of a triangle each measure 34 degrees, the measure of the third interior angle can be calculated as follows:

Finding the sum of the two given angles.

34 + 34 = 68 degrees

Subtracting the sum from 180 degrees.

180 - 68 = 112 degrees

Therefore, the measure of the third interior angle of the triangle is 112 degrees.

In conclusion, the third interior angle of a triangle has a measure of 112 degrees when the first two interior angles of the triangle each measure 34 degrees.

This can be determined by subtracting the sum of the given angles from 180 degrees, as the sum of the interior angles of a triangle is always 180 degrees.
