Answer:

42.5%

Step-by-step explanation:

First we have to complete the table. We know that there are forty part time students so sum(f)=n=40. So, for two courses frequency is 40-11-12=17.

The relative frequency is the proportion of respective frequency and the sum of frequency. So, the missing relative frequency for 1st course is 11/40=0.275.

The missing relative frequency can also be computed as by subtracting given relative frequencies from 1 as sum of relative frequencies is 1. So, 1-0.425-0.3=0.275.

The cumulative frequency of respective class is the sum of frequency of previous classes and frequency of respective class. The missing cumulative frequency is 11+17+12 or 28+12= 40.

So, the complete table is

# of Courses Frequency Relative Frequency Cumulative Frequency

1                        11                   0.275                    11

2                        17                  0.425                    28

3                         12                  0.3                        40

The percent of students takes exactly two courses=0.425*100=42.5%

Answer:

92

Step-by-step explanation:

Start with the first sentence. 7 crates of 12 eggs each and you need to find out how many eggs that is; that's just 12 + 12 + 12 + 12 + 12 + 12 + 12, or 12 * 7, which equals 84.

Real question is: how many do they have now? Well, if they had 8 eggs at first and they just bought 84 more, then the answer is just 8 plus the 84 that they just bought, which is 92.

Please mark as Brainliest! :)

Answer:

Your correct answer is that they now have 76 eggs left.

Step-by-step :

So, to start off, they had 7 boxes with each box with 12 eggs. So multiply 7 by 12.

7 x 12 = 84

Now, they ate 8 eggs.

84 - 8 = 76 eggs

Answer:

U=21

Step-by-step explanation:

What they are asking for is U. They tell you that the cost is 481 so the C is 481

481=20u+61

You minus 61 from 481 which is 420.

420=20u

Then you divide 20 from 420 and you will get 21.

Answer:

Answer:

x = 12

Step-by-step explanation:

insert 2 into the equation where x is.

2(2)2 + 4

so this is 2 * 2 * 2 + 4 = 12

Answer:

Point, Line, and Plane

Step-by-step explanation:

The three undefined terms that form the basis for the subject are a point, a line, and a plane. A point is basically like a dot, which most people should know. A line is a straight one dimensional figure that extends to infinity in both directions. A plane a flat 2 dimension figure, that extends to infinity in all directions. You can think of a plane as infinite lines put next to each other.

You can visualize a point, a line, and a plane in a coordinate grid. A point on the coordinate grid is any point, from (0, 0), the origin, to (2039, pi). A line on the coordinate grid is linear. It can be of any equation from y=x to y=238490/239x + 123. You can think of a plane as the entire coordinate grid.

Answer: 1406.25

Step-by-step explanation:

The soccer field at a park is 9,000 square yards. The soccer field takes up 6 2/5 square inches on the map of the park. How many square yards does 1 square inch on the map represent? Show your work. Help me pls

Given that:

Area of soccer field = 9000 sq yards

Soccer field takes up 6 2/5 square inches on the map of park

Hence,

9000 yd² = 6 2/5 in²

Let 1 in² on map = m

9000 yd² = 32/5 in² - - - (1)

m = 1 in² - - - (2)

Cross multiply ;

6.4 * m = 9000

m = 9000/6.4

m = 1406.25

Hence,

1 in² on map = 1406.25 feet²

x = 13

y = 24

=========================================================

Explanation:

Refer to the diagram below.

The triangle has interior angles (7x-31), 63, and some unknown angle, which we'll call z. This angle z is congruent to (5x-8) as the angles are alternate interior angles.

Alternate interior angles are congruent when we have parallel lines like this.

So z = 5x-8

Add up the three angles inside the triangle, set the sum equal to 180, and solve for x

(angle1)+(angle2)+(angle3) = 180

(7x-31)+63+(5x-8) = 180

12x+24 = 180

12x = 180-24

12x = 156

x = 156/12

x = 13

--------------------------

The angle z mentioned earlier is adjacent to the (4y+27) angle. These two angles form a straight line. They are considered a linear pair. This means they are supplementary (they add to 180)

z+(4y+27) = 180

(5x-8)+(4y+27) = 180

5x + 4y + 19 = 180

5(13) + 4y + 19 = 180

65 + 4y + 19 + 180

4y + 84 = 180

4y = 180-84

4y = 96

y = 96/4

y = 24

Answer:

he walked 7 block's

Jay walks 3 blocks north and then 4 blocks east from his home if he walks straight back home, 5 blocks  does Jay walk-in all

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given,

Jay walks 3 blocks north and then 4 blocks east from his home if he walks straight back home.

We have to use pythagorean theorem in finding distance

As given in the attachment, Let AB= 3

BC=4

AC=x

To find AC we use pythagorean theorem

AC²=AB²+BC²

AC²=3²+4²

AC²=9+16

AC²=25

Take square root on both sides.

AC=5

Hence 5 blocks he walks straight back home how far does Jay walk-in all
