Applying the theorem of angle between intersecting tangents, m<D = 30°.

The theorem states that the angle created by the intersection of two tangent lines at a point outside of a circle is equivalent to half the difference between the measures of the arcs that the tangents intercept.

Given the following:

m<B = 75°

Measure of arc AC = 2(75) [inscribed angle theorem]

Arc AC = 150°

Arc ABC = 360 - 150 = 210°

Based on the theorem of angle between intersecting tangents, we have:

m<D = 1/2(210 - 150)

m<D = 30°

The maximum number of invitations she can buy from each shop will depend on the cost of each invitation.

If the invitations at shop 1 cost £1 each, then she can buy a maximum of 40 invitations from this shop. However, if the invitations at shop 2 cost £2 each, then she can buy a maximum of 20 invitations from this shop.

It is important to consider the quality of the invitations. If the invitations at shop 1 are of higher quality than those at shop 2, then it may be worth spending more money on fewer invitations from shop 1.

Step-by-step explanation:

y = 110 + 32x

Let x = each value in the table and calculate the corresponding value of y.

You get the following.

x = 0; y = 110

x = 2; y = 174

x = 4; y = 238

x = 6; y = 302

x = 8l y = 366

Since every value from evaluating the function gives the same value as the table, then the answer is yes, the table and the equation represent the same function.

From 8 apples and 5 peaches, the probability for the first apple then peach fruit is 40/156.

What is probability?

Probability is defined as a number between zero to one for the analysis of random phenomena.

Given that there are 8 apples and 5 peaches in a basket.

Total Fruits = 13

For the first event, the probability of getting an apple is,

p1=8/13

Now, Total Fruits = 12

For the second event, the probability of getting peach is,

p2=5/12

The probability for both events is given below.

p=p1*p2 = (8/13)*(5/12) = 40/156

Hence we can conclude that the probability for the first apple then peach fruit is 40/156.

The number more than 5 is 6.

Number:

Numbers are mathematical objects used for counting, measuring, and labeling. The original example is the natural numbers 1, 2, 3, 4, etc. [1] Numbers can be linguistically represented by numerals. More generally, individual numbers can be represented by symbols called digits. For example, "5" is the number representing the number five. Since only a relatively small number of symbols can be remembered, basic numbers are usually organized into number systems, which are systematic ways of representing each number. The most common number system is the Hindu-Arabic number system, which can represent any number using combinations of 10 basic numeral symbols called digits.

Greater than Number:

Greater than or equal to in mathematics is an inequality used to compare two or more numbers, quantities, or values. Used when one quantity or number is greater than or greater than the second or remaining quantity or number. This indicates that one value is greater than or greater than or greater than the other. The above symbol is ">". This is also called greater than. We can also compare the length, weight and capacity of the compared number. For example, Bella has a red pencil that is 5 cm long and a blue pencil that is 3 cm long.

Answer:

11 students studied history

21 students studied French

8 students studied both

Step-by-step explanation:

first you have to subtract the number of students who studied both classes.

40-8=32

this leaves you with 32 students to study either history or French.

we know 10 more students studied French than history so subtract that from the 32 students because we already know where they go.

32-10=22

we're left with 22 students that can be equally split between the 2 classes.

22/2=11

so there are 11 more students in each history and French.

but don't forget to add the 10 more students that we already knew were in the French class.

11+10=21

the system of linear equations by graphing - y=-x+7,  y=x+1; values for y is (6,6).

A linear equation is an equation in which the highest power of the variable is 1. The general form of a linear equation is "ax + b = 0", where "a" and "b" are constants and "x" is the variable. For example, "2x + 3 = 0" is a linear equation. The solution to a linear equation is the value(s) of the variable that make the equation true. Linear equations can be solved using various methods such as algebraic manipulation, substitution and elimination. Linear equations can be represented graphically as a straight line, and the solution of the equation is the point where the line crosses the x-axis (or y-axis if the equation is in terms of y). Linear equations have a wide range of applications in many fields, including physics, engineering, economics, and many others.

To solve the system of linear equations by graphing, we can first graph each equation on the coordinate plane.

y = -x + 7 represents a line with a slope of -1 and y-intercept of (0,7) y = x + 1 represents a line with a slope of 1 and y-intercept of (0,1)

If we graph these two lines, we can see that they intersect at a single point, which represents the solution to the system of equations.

The x-coordinate of the point of intersection can be found by setting y equal to each other and solving for x. x = y

And the y-coordinate of the point of intersection can be found by setting x equal to each other and solving for y. y = x

Therefore the solution of the system is (x,y) = (x,x) = (6,6)

So the solution of the system is (6,6)

We can check this point by substitute x=6 and y=6 in each equation of the system and see if it makes both equations true.

y = -6 +7 = 1 y = 6 + 1 = 7

So the point (6,6) is a solution for the system of equations.

It is because the Pythagorean theorem and the Pythagorean identities are based on the properties of right triangles.

What is Pythagorean theorem?

The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. This is the basis for the Pythagorean identities, which relate the sine, cosine, and tangent of an angle to the ratios of the sides of a right triangle.

In a right triangle, one angle is a right angle (90 degrees) and the side opposite the right angle is called the hypotenuse. It is the longest side of the triangle and is always opposite the right angle. The other two sides are called the legs of the triangle, and are referred to as the opposite side and the adjacent side.

The reason that one side is equal to all angles while the other two sides are not, is because the Pythagorean theorem and the Pythagorean identities are based on the properties of right triangles. In a right triangle, the hypotenuse is opposite the right angle and has a unique relationship with the legs, which are the opposite and adjacent sides. This is the foundation of the theorem and identities.

The coordinate plane's formula is (x, y), where x denotes the x-axis and y denotes the y-axis.

A linear equation is a two-variable equation with a line as the graph.

A collection of points in the coordinate plane that are all solutions to the equation make up the graph of the linear equation.

If every variable has a real value, the equation can be graphed by placing enough points on the graph to identify a pattern, then connecting those points to include all of the points.

A linear equation must have at least two points in order to be graphed, however it's usually a good idea to utilize more.

Try to include zero as well as both positive and negative numbers when selecting your points.

The probability that a student passed the test given that they completed the homework is 0.8 (or 80%).

To calculate this probability, we can use the formula:

P(A|B) = P(A and B) / P(B)

Where A is the event of passing the test and B is the event of completing the homework.P(A and B) is the probability that a student both passed the test and completed the homework, which is the number of students who did both divided by the total number of students in the class.

16 students passed the test and completed the homework of 28 students in total, so:

P(A and B) = 16/28 = 0.57

P(B) is the probability that a student completed the homework, which is the number of students who completed the homework divided by the total number of students in the class.

19 students completed the homework out of 28 students in total, so:

P(B) = 19/28 = 0.68

Now we can use these values to find the probability that a student passed the test given that they completed the homework:
