In the diagram below, D is a point on segment CE such that segments AD and BE are parellel and point A is not on segment BC. Line segments AD and BC intersect at point P.

If angle CAD = 67 degrees, then what is angle CBE?

Answer:

Step-by-step explanation:

Firstly, lets just add the fractions we got.

2/5 + 1/3 = 6/15 + 5/15 = 11/15

So, 11/15 of the total students bought stuff other than drinks.

Number of people who bought drinks will be the people left

So, 1 - 11/15, or 4/15

a) 4/15

b) Fraction of people who bought beef burger is 2/5.

2/5 x 3/4 = 3/10

So the fraction is 3/10.

The quadratic equation for the given roots is x²-2x-1=0. Therefore, option 4 is the correct answer.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The roots of the quadratic equation are 1±√2.

Here, x=1+√2 and x=1-√2

x-1-√2=0 and x-1+√2=0

Now, (x-1-√2)(x-1+√2)=0

= x(x-1+√2)-1(x-1+√2)-√2(x-1+√2)=0

= x²-x+√2x-x+1-√2-√2x+√2-2=0

= x²-2x-1=0

Therefore, option 4 is the correct answer.

Answer:

21 and 18.48 respectively

Step-by-step explanation:

to solve this question,first we need to identify the quotients by dividing the numbers and multiply each by 21/5

The quotient of the [tex]\frac{55}{11}[/tex]=5

[tex]\frac{21}{5}[/tex]  of 5 = [tex]\frac{21}{5}[/tex]×5=21

The quotient of the [tex]\frac{22}{5}[/tex]=4.4

[tex]\frac{21}{5}[/tex] of 4.4 = [tex]\frac{21}{5}[/tex]×4.4=18.4

Answer:

The inequality that can be used to solve for how many x paintings can be displayed is 22x + 9 <= 315

Step-by-step explanation:

This inequality states that the total square footage of the paintings and the sign must be less than or equal to 315 square feet. Each painting takes up 22 square feet, and the sign takes up 9 square feet, so the total square footage is represented by the expression 22x + 9.

The inequality states that 22x + 9 <= 315 which means for any number of paintings she displays it should be less than or equal to 315 sq.ft.

The other options:

22x + 9 315: the inequality is less than instead of less than or equal to, which means that the total cost should be less than 315 sq.ft which is not always the case.

22x + 92 315: the coefficient of x is 22 instead of 22 and the 92 is placed in a wrong position.

9x+22 315: the coefficient of x is 9 instead of 22 and the 22 is placed in a wrong position.

22z + 9 315: the variable used is z instead of x

The point (-1, 6) is on the lines y = 5x + 3 and y = 2x + 4​

From the question, we have the following parameters that can be used in our computation:

Point = (-1, 6)

Also, we have

y = 5x + 3

y = 2x + 4​

Substitute the known values in the above equation, so, we have the following representation

6 = 5(-1) + 3 = -2 -- false

6 = 2(-1) + 4 = 2 --- false

The measures, using the Law of Sines, are given as follows:

The law of sines states that the ratio between the sine of each angle and the side length opposite to this angle has to be equal for all the angles in the problem.

The sum of the measures of the internal angles of a triangle is of 180º, hence the measure of angle B is given as follows:

m < B + 25 + 36 = 180

m < B = 180 - (25 + 36)

m < B = 119º.

Then the length BC is obtained as follows:

sin(25º)/BC = sin(36º)/28

BC = 28 x sin(25º)/sin(36º)

BC = 20.13.

The length AC is obtained as follows:

sin(119º)/AC = sin(36º)/28

AC = 28 x sin(119º)/sin(36º)

AC = 41.62.

If D and R are independent, then P(D or R) = 0.8412

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B)

P(D) = 0.26 and P( R) = 0.26 , if D and R are independent, then,

P(D or R) = P(D) + P(R) - P(DnR)

then P(DnR) = P(D) × P(R) = 0.26×0.38 = 0.0988

P(D or R) = 0.26+0.38-0.0988

= 0.8412

If you select 5 samples starting from student number 8, the possible samples are student 8, 16, 24, 32, and 40.

A sample can be defined as small group taken from a population that can be used to study the whole population, and therefore to determine patterns, behaviors, preferences, etc. in the population.

Due to this, samples simplify the research process and make it feasible as in most cases the whole popualtion cannot be studied.

Although there are many methods for selecting a sample, one of the methods that is more commonly used is the random sampling in which participants are given a number and then the sample is chosen by using this numbers either by selecting the numbers randomly or as in this case by following a sequence.

Based on this principle, the possible samples are student 8, 16, 24, 32, and 40, if we start with student 8 and use this sequence.

where m is the slope and (a, b ) a point on the line

here m = - [tex]\frac{2}{3}[/tex] and (a, b ) = ( - 11, - 13 ) , then

Answer:

Step-by-step explanation:

The value of y is pi over 6. To solve for y, we use the fact that the sine of a sum is equal to the sum of the sines of each individual angle multiplied by the cosine of the other angle. This can be expressed mathematically as sin(x+y) = sin(x)cos(y) + cos(x)sin(y).

Substituting the given values into the equation, we have:

sin(x+y) = (√2/2)sin(x) + (√2/2)cos(x)

Rearranging, we can solve for y:

y = arcsin((√2/2)sin(x) + (√2/2)cos(x)) - x

Since x is equal to pi over 2, we can calculate y as follows:

y = arcsin((√2/2)sin(pi/2) + (√2/2)cos(pi/2)) - (pi/2)

= arcsin((√2/2)(1) + (√2/2)(0)) - (pi/2)

= arcsin(√2/2) - (pi/2)

= pi/6

Therefore, the value of y is pi over 6.

Answer:

We know that the ratio of female students to the total number of students is 4 to 9.

That means that for every 4 female students, there are 9 students in total.

So, we can set up the proportion:

4/9 = x/264

where x is the total number of students.

Solving for x, we get:

x = (4/9)*264 = 96

Since the ratio of teachers to students is 1 to 11, then for every 11 students there is 1 teacher, we can set up the proportion:

1/11 = y/96

where y is the total number of teachers.

Solving for y, we get:

y = (1/11)*96 = 8.72 ≈ 8

So, there are 8 teachers in the college.

Step-by-step explanation:

We can simplify the expression to get:

2³ + 3*(2) + 14/2 = 21

The correct option is E.

Here we want to simplify the expression below:

2³ + 3*(2) + 14/2

The additions are the last thing we need to do, we can replace:

2³ = 8

3*(2) = 6

14/2 = 7

Replacing that in the expression we will get:

2³ + 3*(2) + 14/2 = 8 + 6 + 7

8 + 6 + 7 = 21

Answer:

131.25 feet.

Step-by-step explanation:

We can use the concept of similar triangles to find the length of the monument's shadow.

Since the pole and the monument are casting the shadows, we can assume that the ratio of the height of the pole to the length of its shadow is equal to the ratio of the height of the monument to the length of its shadow.

12/5 = 315/x

Where x is the length of the monument's shadow.

We can cross-multiply and solve for x:

12x = 5315

x = 5*315/12

x = 131.25

So, the length of the monument's shadow is approximately 131.25 feet.
