Answer:

Let the total no of girls be x

the number of boys=7:5

total no of students =20

now,

no of girls =7/5=x/20

or, 20*7=5x

or 140=5x

or,x=140/5=28

therefore the number of girls =28

Answer:

y = 75

Step-by-step explanation:

Given that:

   y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]

⇒ y = k[tex]\sqrt{x}[/tex]

where k is the constant of proportionality.

When y = 45, x = 81, then;

45 = k[tex]\sqrt{81}[/tex]

45 = 9 k

k = [tex]\frac{45}{9}[/tex]

  = 5

k = 5

So that,

y = 5[tex]\sqrt{x}[/tex]

the value of y when x = 225 is;

y = 5[tex]\sqrt{x}[/tex]

  = 5 x [tex]\sqrt{225}[/tex]

  = 5 x 15

y = 75

Step-by-step explanation:

The probability of students response is milk is 0.311.

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

The table shows the students preference of milk, juice or water.

Total number of students preferred milk = 14

Total number of students = 45

Thus the probability that the students response is milk is

[tex]P(e)=\frac{14}{45}[/tex]

⇒ [tex]P(e)= 0.311[/tex]

Hence  we can conclude that the probability of students response is milk is 0.311.

x + 14 [tex]\frac{13}{25}[/tex]  =  -0.87

x + [tex]\frac{363}{25}[/tex] = - [tex]\frac{87}{100}[/tex]

x + [tex]\frac{1452}{100}[/tex] = - [tex]\frac{87}{100}[/tex]

Answer:

Slope

Step-by-step explanation:

The equation of lines are normally formatted in "slope-intercept form"

(y = mx + b)

The b in the equation would be the y-intercept of the line.

The m represents the slope.

The x and y can be replaced with any x and y value from the line (if necessary)

Answer: it should be a positive sraignt line, just plot the points as it shows you, and you should get a positive slope line.

Me to I need that Answer en m<k is 50°

Step-by-step explanation:

The measure of KL is 5.1 unit and the measure of ML is 6.1 unit.

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given that, MK=8 units, ∠M=40° and ∠K=50°.

We know that, sinθ=Perpendicular/Hypotenuse

Now, sin40°=KL/8

0.6427=KL/8

KL=0.6427×8

KL=5.1 units

sin50°=ML/8

0.7660=ML/8

ML=6.1 units

Therefore, the measure of KL is 5.1 unit and the measure of ML is 6.1 unit.

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

Hello There!

First things first, we should find the rate of change / slope

given two points we can find the slope by using the slope formula which is

(let m be slope)

[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]

To find the slope all we have to do is plug in the points

(1,5),(2,10)

remember the first numbers in an ordered pair are the x values and the second numbers are the y values

we also plug in the points of the second ordered pair first so

[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]

Knowing the slope we can create an equation to find the x value (a)

y=5x

given the y value we plug in y and solve for x

15=5x

divide each side by 5

15/5=3

5x/5=x

we're left with

x=3

so we can conclude when y =15 x = 3 therefore 3 is your answer
