Answers

Answer 1

Answer:

Angle BCD is 13 degrees

Step-by-step explanation:

Here, we want to find the measure of angle BCD

To get this, we need an appropriate diagram. The diagram can be seen in the attachment.

To find the value of BCD, we can use an important triangle theorem.

This is that the sum of opposite interior angles of a triangle equals the exterior angle.

Thus, we have that;

BCD + DBC = CDE

hence;

3x + 5 + 2x + 3 = 9x-12

5x + 8 = 9x -12

9x-5x = 8 + 12

4x = 20

x = 20/4

x = 5

So the measure of BCD will be 2(5) + 3 = 10 + 3 = 13

In BCD, \overline{BD} BD Is Extended Through Point D To Point E, \text{m}\angle CDE = (9x-12)^{\circ}mCDE=(9x12)

Answers

Answer:

88 degrees

Step-by-step explanation:

First, notice that when you rotate a point 272 degrees clockwise, there will be 88 more degrees before it returns to its original point (since a 360 turn is equivalent to not moving, and 360-272=88).

Because of that, we can deduce that rotating a point 88 degrees counterclockwise will be equivalent to rotating it 272 degrees clockwise.

We can know that that's the smallest possible positive answer, because any angle smaller than 360 will be the smallest possible way to express it.

Hello!, All I wanted to ask was what is the answer to this question “Evaluate 9 + 7 x 5”

Evaluate basically means to solve. So using order of operations, you first multiply 7 and 5 and get 35, then add 9 to get 44. So 44 would be your final answer.

Step-by-step explanation:

For a recent season in college football, the total number of rushing yards for that season is recorded for each running back. The mean number of rushing yards for the running backs that season is 790 yards. One running back had 1,637 rushing yards for the season, which is 2.42 standard deviations above the mean number of rushing yards. What is the standard deviation of the number of rushing yards for the running backs that season?

(A) 250 yards

(B) 300 yards

(C) 350 yards

(D) 400 yards

(E) 450 yards

Answers

Answer:

(C) 350 yards

Step-by-step explanation:

From available information

Mean = 790

1 running back = 1637 yards

Standard deviation above mean = 2.42

Using formula

z =( x - mean)/sd

2.42 = (1637-790)/sd

2.42 = 847/sd

We cross multiply

2.42sd = 847

Divide through by 2.42

Sd = 847/2.42

Sd = standard deviation = 350

So our answer is 350 and therefore option c.

A printing machine produces labels.Four percent of the labels produced are defective.Suppose 372 labels were defective.
how many labels are not defective?

Answers

Answer:

8928

Step-by-step explanation:

If 4% is 374, what is 1%? so 374/4

374 = 4%

93 = 1%

Now if 4% is defective, how many is not defective?

100% - 4% = 96%

If 1% is 93 then what is 100%?

8928 = 96%

There were 8,928 labels are not defective.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

We have been given that labels are created using a printing press. Four percent of the labels that are created are inaccurate.

Let the total number of labels would be x

As per the question, 372 labels were defective.

So 4% of x = 372

⇒ 4x/100 = 372

⇒ x = 37,200/4

⇒ x = 9,300

Since 4% is defective labels,

So labels are not defective: 100% - 4% = 96%

Now, we have to calculate the evaluation of 96% of 9,300.

⇒ (96/100)9,300

⇒ (0.96)9,300

⇒ 8,928

Therefore, there were 8,928 labels are not defective.

What do the differences between the points (as shown on the graph) represent?
Please answer

Answers

Answer:

Answer:

They represent the rise and run of the graph.

Step-by-step explanation:

Step-by-step explanation:

The difference between the x-axis of the points represents the "run" of the graph (or how much you should run along x-axis to get to the next point.)

The difference between the y-axis of of the points represents the "rise" of the graph (or how much you should rise up the y-xis to get to the next point).

The ratio of rise to run is the slope of the graph, which tells us  how many steps should we take on the y-axis for every step we move forward on the x-axis.

They represent the rise and run of the graph.  

The difference between the x-axis of the points represents the" run" of the graph( or how  important you should run along x-axis to get to the coming point.)  The difference between the y- axis of of the points represents the" rise" of the graph( or how  important you should rise up the y- x is to get to the coming point).  

The  rate of rise to run is the slope of the graph, which tells us how  numerous  way should we take on the y- axis for every step we move forward on the x-axis.
