The likelihood of selecting a classmate at random who does not have an A is 6/19.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

To find the probability of a student not having an A, we need to first find the total number of students who do not have an A.

The number of students who have an A is 13, so the number of students who do not have an A is:

19 - 13 = 6

Out of these 6 students, 4 are male and 2 are female.

So, the probability of choosing a student randomly who does not have an A is:

P(not A) = number of students without an A / total number of students

P(not A) = 6 / 19

Therefore, the probability of choosing a student randomly from the class who does not have an A is 6/19.

Answer:

  (1+√2)/2 ≈ 1.207 cm

Step-by-step explanation:

The angled flats are at 45°, so the length in the direction of a vertical or horizontal radius is (1 cm)/√2 = (1/2)√2 cm. The remaining length of that radius is half the length of a flat, so is 1/2 cm. The total length of the radius is ...

  1/2 + 1/2√2 = (1+√2)/2 ≈ 1.207 cm

_____

In trigonometry terms, the length of the flat is ...

  1 cm = 2(r)(tan(45°/2))

so the radius is ...

  r = (1 cm)/(2·tan(22.5°))

  r = (1/2)cot(22.5°) ≈ 1.207

Answer:

1- effect of cause

2- effect of cause

4- effect of cause

Answer:

2 incorrect answers

Step-by-step explanation:

If you take the percentage correct, you will notice its a particularly high score for the amount of questions. In this case, instead of using a really long theorem, its much simpler to just input numbers.

To find your score on a test out of 100%, you take your amount correct and divide it by the total number of questions, then multiply by 100.

If you take 24/25, you get 0.96, which if multiplied 100*0.96=96%

Now its simple, just go 23/25 to get 0.92, multiplied 100*0.92=92% correct, 25-23=2 so the amount of incorrect answers would be 2.

........Option C ) n × 2 = t

Step-by-step explanation:

Hey there!

In (a) part let us take the value of n as 1 first.

n + 2

=> 1+2

= 3

But it doesn't get matched with t.

So, (a) option cancelled.

In (b) part, let us take the value of n as 1.

n - 2

=> 1 - 2

= -1

But this also didn't match with t.

Option (b) cancelled.

In (c) part, let us take the value of n as 1.

n × 2

=> 1 × 2

= 2

Matched! Let us check further. Taking value of n as 2,

=> 2 × 2

= 4

Matched again! So, (c) part is the correct answer.

Let us take the value of n as 1. (For both option (d) and (e))

n + 3

=> 1 + 3

= 4 (wrong)

n + 4

=> 1 + 4

= 5 (wrong)

So, (c) part is the right answer.

Hope it helps :)

Answer:

A person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.

Step-by-step explanation:

You can write an equation in which the amount charged by bank a is equal to the amount charged by bank b. The amount bank a charges is 6 plus 0.10 for the number of checks written and the amount bank b charges is 5.20 for the number of checks written.

6+0.10x=5.20x, where x is the number of checks written

Now, you can solve for x to find the number of checks written where the two banks charge the same amounts in fees:

6=5.20x-0.10x

6=5.10x

x=6/5.10

x=1.17

According to this, the answer is that a person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.

Answer:

16.28 m^2

Step-by-step explanation:

The bottom portion of this figure is a trapezoid with lengths 4 m and 6 m.

Thus, the average length of this trapezoid is 5 m, and the height is 2 m.  This leads to (5 m)(2 m) = 10 m as the area.

The upper portion is a semicircle of radius 2 m.  The area of this semicircle is

A = (pi)r^2 / 2, which here is A = (pi/2)(2 m)^2, or approximately 6.28 m^2.

Thus, the area of the entire purple figure is 16.28 m^2.

Answer:

The area in square meter is 412,500 square meters

the price per square meter is 500 pesos per square meter

Step-by-step explanation:

Firstly, let us get the measure of the dimensions in meters

Mathematically, 1000 m = 1 km

Thus;

0.75 km = 0.75 * 1000 = 750 m

The area of a rectangle is the product of its side lengths

mathematically, we have this as;

550 * 750 = 412,500 square meters

To get the price per square meter, we have to divide the price of the whole plot by the area

So we have ;

(206,250,000) pesos / 412,500 square meters

= 500 pesos per square meter

Answer:

The solution is (-1/2, -2)

Step-by-step explanation:

Given 6f-4g=1,6f-6g=5, write these in columnar form:

6f-4g=1

6f-6g=5

Change all of the signs in the first equation:

-6f + 4g = -1

 6f-6g=5

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

     -2g = 4, and so g = -2

Substituting -2 for g in either equation enables us to find f.  Let's use the first equation:    6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3

Then f = -1/2 and g = -2.  The solution is (-1/2, -2)

the answer is x = -2
