Angela made 23 cards for her friends. She wants to make 19 more cards. How many cards will she make in all?
By using addition calculation, we determine that Angela will end up making 42 cards in total.
Angela made 23 cards for her friends, but she wants to make even more to share with others. To determine how many cards she will make in total, we need to add the number of cards she has already made with the number of cards she plans to make.
So, we add 23 (the number of cards she has made) and 19 (the number of cards she plans to make) so in total, she will make:
23 + 19 = 42
Therefore, Angela will make 42 cards in all.
By using simple arithmetic calculation of basic addition, we find that Angela will make 42 cards in all.

Therefore, the exponential function that passes through the points (2,45) and (5,3072) is: y = (45/16) ([tex]4^{x}[/tex]).
What is function?In mathematics, a function is a rule that assigns to each element in a set called the domain, a unique element in another set called the range. In other words, a function is a mathematical object that takes an input and produces a specific output, according to a specific set of rules or operations.
by the question.
The general form of the exponential function is y = [tex]ab^{x}[/tex] where a and b are constants. To find the values of a and b that satisfy the given conditions, we can use the two points (2,45) and (5,3072) and solve for a and b.
First, we can write two equations based on the two points:
45 = a[tex]b^{2}[/tex] (1)
3072 = ab^5 (2)
We can then divide (2) by (1) to eliminate a:
3072/45 = (a[tex]b^{5}[/tex])/ (a[tex]b^{2}[/tex])
68 = [tex]b^{3}[/tex]
Solving for b, we get:
b = 4

if a data set is symmetrical, which statistical measure best represents the entire spread of the data set?
The best statistical measure to represent the entire spread of the data set when a data set is symmetrical is the standard deviation.
The standard deviation is a measure of how much the individual data points vary from the mean of the data set.
It is calculated by taking the square root of the variance.
It is the average of the squared differences of each data point from the mean.
In a symmetrical data set, the mean, median, and mode are all equal and located at the center of the data set.
This represents that the data points are evenly distributed around the center.
The standard deviation can provide a good measure of the spread of the data points from this center.
Other measures of spread representing the range or interquartile range, may not be as useful in a symmetrical data set .
As they are more affected by outliers and skewness in the data.
Therefore, the symmetrical data set in best way represented by statistical measure known as standard deviation.

a) Graph this system of inequalities, we can plot the lines x = 0, y = 0, x = 260, y = 320, and x + y = 380
b) The maximum profit of $5200 achieved.
Define the term selling profit?Selling profit is the profit that a business makes on the sale of its products or services. It is the difference between the selling price and the cost of product.
a) Let x be the number of boards of mahogany sold and y be the number of boards of black walnut sold. Then, the constraints of the problem can be represented by the following system of inequalities:
x ≥ 0 (non-negative constraint)
y ≥ 0 (non-negative constraint)
x ≤ 260 (maximum number of mahogany boards available)
y ≤ 320 (maximum number of black walnut boards available)
x + y ≤ 380 (maximum number of boards that can be sold)
To graph this system of inequalities, we can plot the lines x = 0, y = 0, x = 260, y = 320, and x + y = 380 on a coordinate plane and shade the feasible region that satisfies all of the constraints. The feasible region is the area that is bounded by these lines and includes the origin (0, 0).
b) The profit function P(x, y) can be defined as follows:
P(x, y) = 20x + 6y
To maximize the profit, we need to find the values of x and y that satisfy all of the constraints and maximize the profit function P(x, y).
One way to do this is to use the corner-point method. We can evaluate the profit function at each of the corners of the feasible region and find the corner that gives the maximum profit.
The corners of the feasible region are (0, 0), (0, 320), (260, 0), and (120, 260).
P(0, 0) = 0
P(0, 320) = 6(320) = 1920
P(260, 0) = 20(260) = 5200
P(120, 260) = 20(120) + 6(260) = 4720
Therefore, the maximum profit of $5200 can be achieved by selling 260 boards of mahogany and 0 boards of black walnut.

In a study of the effects of marijuana during pregnancy, measurements on babies of mother who used marijuana during pregnany were compared to measurements on babies of mothers who did not. A 95% confidence interval for the difference in mean head circumference (nonuse minus use) was .61 to 1.19 cm. What can be said from this statement about a p-value for the hypothesis that the mean difference is zero?
The 95% confidence interval of .61 to 1.19 cm provides strong evidence that there is a difference in mean head circumference between babies of mothers who used marijuana during pregnancy and those who did not. Furthermore, the small p-value suggests that the mean difference is statistically significant, and is not likely to be zero.
The 95% confidence interval for the difference in mean head circumference between babies of mothers who used marijuana during pregnancy and those who did not is .61 to 1.19 cm. This implies that the true mean difference is likely to be between .61 and 1.19 cm. The p-value is a measure of how likely it is that the difference in means is zero, and can be used to assess the statistical significance of the difference in means.
Therefore, the p-value for the hypothesis that the mean difference is zero is very small and can be considered statistically significant.

The small p-value suggests that the mean difference is statistically significant, and is not likely to be zero.
A 95% confidence interval (CI) is a range of values that is expected to include the true population mean with a probability of 0.95. The CI for the difference in mean head circumference between non-users and users of marijuana during pregnancy is 0.61 to 1.19 cm.
This means that the sample mean difference (nonuse minus use) falls within this interval.
If the true population mean difference were zero, the sample mean difference would fall within the range of random sampling error, and the null hypothesis that there is no difference between the groups would be supported.
However, since the 95% CI does not include zero, we can conclude that the difference is statistically significant at the 0.05 level.

The answer to this question is the solution to what equation? [Let a represent the number of years since the beginning of 2020.] Preview b. Solve the equation in part (a)
a. The answer to this question is the solution to the equation:
84000(1 + 0.04)^a = 132000
Where "a" represents the number of years since the beginning of 2020, and 0.04 is the decimal equivalent of 4%.
We use the formula for compound interest, which is A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the interest rate, n is the number of times interest is compounded per year, and t is the time in years. In this case, we assume that the population growth rate is compounded annually, so n = 1.
b. Solving the equation in part (a), we get:
(1 + 0.04)^a = 132000/84000
1.04^a = 1.5714
a = log(1.5714)/log(1.04)

x + y = 15
The system of equations x + y = 15 and 2x + 3y = 24
What is an equation?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
To substitute for the variable x in the equation x + y = 15, we can rearrange the equation to solve for x in terms of y:
x = 15 - y
Then we can substitute this expression for x in any other equation that involves x.
2(15 - y) + 3y = 24
Simplifying this equation gives:
30 - 2y + 3y = 24
y = -6
Then we can substitute this value back into our expression for x to get:
x = 15 - (-6) = 21
So the solution to the system of equations x + y = 15 and 2x + 3y = 24 is (x, y) = (21, -6), but the question only asked us to rewrite the equation to substitute for x.

How to find the length of the median of a triangle?
Given that the centroid of a triangle is located 12 units from one of the vertices of a triangle. We need to find the length of the median of the triangle drawn from that same vertex.
Let ABC be a triangle.
Let AD be median of the triangle.
Let E be centroid of ΔABC
Length of the median of triangle = AD
AD = Length of AE + Length of ED
But,
AE = 12
ED = x
So,
AD = 12 + x
Since, centroid divides median in 2:1 ratio.
Then,

ABCD is a quadrilateral in which BD = 15 cm., perpendiculars from A and Con BD are 6 cm and 8 cm respectively. Calculate the area of the quadrilaterals
The area of the quadrilateral is 161.24 cm².
How to deal with quadrilateral?We can see that we can divide the quadrilateral into two triangles: ABD and CBD. We know that the height of ABD is 6 cm and the height of CBD is 8 cm. We also know that BD is 15 cm. To find the area of each triangle, we need to find the base of each triangle. We can do this using the Pythagorean theorem.
For triangle ABD:
AB² = AD² + BD²
AB² = (6 cm)² + (15 cm)²
AB² = 261 cm²
AB = [tex]\sqrt(261) cm[/tex]
For triangle CBD:
BC² = CD² + BD²
BC² = (8 cm)² + (15 cm)²
BC² = 289 cm²
BC = 17 cm
Now we can find the areas of the triangles:
Area of ABD =[tex]\frac{1}{2}[/tex] * AB * 6 cm
Area of ABD = [tex]\frac{1}{2}[/tex] * [tex]\sqrt(261) cm[/tex] * 6 cm
Area of ABD = 93.24 cm^2
Area of CBD = [tex]\frac{1}{2}[/tex] * BC * 8 cm
Area of CBD = [tex]\frac{1}{2}[/tex] * 17 cm * 8 cm
Area of CBD = 68 cm²
Finally, we can find the area of the quadrilateral by adding the areas of the triangles:
Area of ABCD = Area of ABD + Area of CBD
Area of ABCD = 93.24 cm² + 68 cm²
Area of ABCD = 161.24 cm²
Therefore, the area of the quadrilateral is 161.24 cm².

To calculate the average speed of Idil's car in miles per hour, we need to divide the distance she drove (12 miles) by the time it took her to drive that distance (1/5 hour):
Average speed = distance ÷ time
Average speed = 12 miles ÷ (1/5) hour
To divide by a fraction, we can multiply by its reciprocal, so:
Average speed = 12 miles × 5/1 hour
Average speed = 60 miles per hour
Therefore, Idil drove at an average speed of 60 miles per hour.
