the probability that a randomly selected student is either a woman or earning an A is 0.625 or 62.5%.

To find the probability that a randomly selected student is either a woman or earning an A, we need to calculate the total number of students who fall into either category and divide it by the total number of students in the class.

Given that there are 40 students in the class, we know that 22 are women and 10 are earning an A. However, 7 of the women are also earning an A, so we need to subtract this overlap to avoid double-counting.

Therefore, the number of students who are either women or earning an A is 22 + 10 - 7 = 25.

The probability can now be calculated by dividing this number by the total number of students in the class: 25/40 = 0.625.

So, the probability that a randomly selected student is either a woman or earning an A is 0.625 or 62.5%.

Step-by-step explanation:

Integers are the positive and negative whole numbers & 0.

No fractions or decimals.

For C we get

C = (A-b)/εm

Substract your y-intercept from the absorbance and divide by the slope

Beer's law, or Beer-Lambert law, is a relation between the concentration, degree of attenuation, optical path length, and absorbance of a solution. This law is often employed in the analysis of chemicals as it is a straightforward relation. The law was named after August Beer and Johann Heinrich Lambert.

The basic idea here is to use a graph plotting Absorbance vs. Concentration of known solutions. Once you have that you can compare the absorbance value of an unknown sample to figure out its concentration.

You will be applying Beer's law to calculate the concentration.

The equation for Beer's law is: A = εmCl

(A=absorbance, εm = molar extinction coefficient, C = concentration, l=path length of 1 cm)

You should have a data set which was used to create a standard curve. The graph should plot concentration (independent variable) on the x-axis and absorption (dependent variable) on the y axis.

You'll need to add a line of best fit to the data points and determine the equation for the line. The equation should be in y=mx + b form.

y = absorbance (A)

Note: no unit for absorbance

x = concentration (C)

Note: unit is M or mol/L

m = (εm) = slope or the molar extinction coefficient in beers law which has units of \(M^-^1cm^-^1\)

So A = εmC +b

If you solve for C you should get

C = (A-b)/εm

So if you substract your y-intercept from the absorbance and divide by the slope, you are finding the concentration of your sample.

Answer: 13512

100332

Step-by-step explanation:

The shortest time for her run is approximately 36 minutes and the longest time is approximately 67 minutes.

To represent Kenzie's situation, we can use an absolute value equation. Let x represent the length of her run in miles.

The equation would then be |x - 6| ≤ 1, which means the distance between x and 6 is less than or equal to 1.

To find the shortest or longest amount of time for Kenzie's run, we need to consider the speed.

The time can be found by dividing the distance by the speed, so the minimum time would be (6 - 1)/6.25 hours,

which is approximately 0.6 hours or 36 minutes.

The maximum time would be (6 + 1)/6.25 hours,

which is approximately 1.12 hours or 67 minutes.

Answer:

d) 303 8/9

Step-by-step explanation:

4th term = ar^3  and 5th = ar^4   where a = first term and r = common ratio.

So ar^4 / ar^3

= r = 45/-15 = -3.

Working back,:

The first term a = ar^3/ r^3

= -15 / (-3)^3

= -15/-27

= 5/9

Sum of n terms = a * (r^n - 1)/(r-1)

= 5/9 * ((-3)^7 - 1 ) / (-3 -1)

Answer:

17.5

Step-by-step explanation:

all the 10 numbers added together equal 10*16 = 160

-this is because all of the numbers added, and then divided by 10 equals 16

so the numbers in total, added equal 160.

subtract 20 (7+13) from 160 = 140

divide by 8

140/8 = 17.5

The degree of the polynomial 4x²y is 3

The degree of a polynomial is the highest of the degrees of the polynomial's monomials with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer.

For example, polynomial 3x³+ 5xy² has a degree of 3, because the sum of the power of variable x¹ and y ² = 1+2 = 3

Similarly, the polynomial 4x²y has two variables

x² and y

The power of x² is 2 and the power of y is 1.

Therefore the degree of the polynomial is 2+1 = 3

This means that the degree of the polynomial 4x²y is 3

Answer:

Step-by-step explanation:

Precision is defined as the ratio of true positives (TP) to the total predicted positives (TP + FP). In this case, the confusion matrix shows 46 TP and 4 FP, so the precision can be calculated as:

precision = TP / (TP + FP) = 46 / (46 + 4) = 0.92

Rounding to 2 decimal places, the precision ratio is 0.92.

4/3 lemons

Step-by-step explanation:

For 16 lemons per 12 cups, simplify the ratio to 4 lemons per 3 cups.

The required rate of lemon per cup of lemonade is 1.34 lemons per cup.

Given that,
For Allison's lemonade recipe, 16 lemons are required to make 12 cups of lemonade. At what rate are lemons being used in lemons per cup of lemonade to be determined.

The rate of change is defined as the change in value with the rest of the time is called the rate of change.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Since
Let the rate of lemon per cup of lemonade is x,
Total lemon = 16
To a cup of lemonade = 12
Rate of lemon per cup of lemonade
x = 16/12
x = 1.34

Thus, the required rate of lemon per cup of lemonade is 1.34 lemons per cup.

Complementary angles

Step-by-step explanation:

Complementary angles are when two angles add up to 90 degrees.

3x + 10 + 47 = 90

3x + 10 = 43

3x = 33

x = 11

The line represented by the table is:

y = 2x + 40

A general linear relationship is written as:

y = ax + b

Where a is the slope and b is the y-intercept.

If the line passes through (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

We can use the first two pairs:

(6, 52) and (9, 58)

Then we will get:

a = (58 - 52)/(9 - 6)

a = 6/3 = 2

y = 2x + b

To find the value of b, we replace the values of one of the points, if we use the first one (6, 52), then we will get:

52 = 2*6 + b

52 = 12 + b

52 - 12 = b

40 = b

The line is:

y = 2x + 40

Time taken by Matilda on each project is \(5\frac{7}{12}\) hours.

According to the question we have been given that,

Total time taken by Matilda to complete the consulting projects = \(16\frac{3}{4}\) hours

First we will convert it into simple fraction which is

         \(16\frac{3}{4} = \frac{67}{4} \\\) hours

Number of consulting projects = 3

And Matilda spends same amount of time to each of the project.

To find the time she spend on each project is by using unitary method

that is,            3 projects = \(\frac{67}{4}\) hours

                      1 project = \(\frac{67}{4} / 3\)

                                     = 67/12

                                     = \(5\frac{7}{12}\) hours
