Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810      Eqn 1

y = 5x         Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{810}{6}\\x=135[/tex]

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675

Given:

The equation is

[tex]5^x=55[/tex]

To find:

The value of x.

Solution:

We have,

[tex]5^x=55[/tex]

Taking log both sides, we get

[tex]\log (5^x)=\log (55)[/tex]

[tex]x\log (5)=\log (55)[/tex]        [tex][\because \log x^n=n\log x][/tex]

[tex]x=\dfrac{\log (55)}{\log (5)}[/tex]

Using the log values, we get

[tex]x=\dfrac{1.740}{0.699}[/tex]

[tex]x=2.48927[/tex]

[tex]x\approx 2.49[/tex]

Therefore, the correct option is B.

Answer: 3. 2

Step-by-step explanation:

Given the data:

3.12 2.45 4.0 3.76 3.54 2.78 3.39 3.21 1.98 3.43 3.98 2.77

Point estimate of population mean :

Σx / N

(3.12 + 2.45 + 4.0 + 3.76+ 3.54 + 2.78 + 3.39 + 3.21 + 1.98 + 3.43 + 3.98 + 2.77)

= 38.41 / 12

= 3.2008

Answer:

(x-1)²/49 + (y+3)²/16.51 = 1

Step-by-step explanation:

vertex (8,-3)     Foci (6.7,-3)   center (h,k) = (1,-3) , major axis parallel to x axis

a  is the distance of the vertex from the center, and c   is the distance of the foci from the center. b is semi-minor axis

b² = a² - c²         Ellipse equation: (x-h)²/a² + (y-k)²/b² = 1

a = 8-1 = 7         c = 6.7 - 1 = 5.7

b² = 7² - 5.7² = 16.51

Ellipse equation:  (x-1)²/49 + (y- -3)²/16.51 = 1  i.e. (x-1)²/49 + (y+3)²/16.51 = 1

Answer:

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope

Answer:

5.5

Step-by-step explanation:

Given the set of data

5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

The average of the least and the greatest value is known as the midrange

The formula for calculating the midrange is expressed as shown:

Midrange = (Greatest value + Least value)/2

Given

Greatest value = 10

Least value = 1

Midrange = 10+1/2

Midrange = 11/2

Midrange = 5.5

Hence the midrange of the data is 5.5

Answer:

The triple constraint represents the three constraints or inputs which control the project's capacity to produce.

The three components are Budget, time, and scope.

The relationship between them is an interdependent or triangular shape.

Step-by-step explanation:

The triple constraint represents the three constraints or inputs which control the project's capacity to produce. Budget, Scope and Time.

These 3 components are dependent to each other.

For example, if time is restricted then scope and budget will be affected. similarly.

The relationship between the three is that one of the two other components must decrease while one component increases for the project to succeed as expected.

Answer:

Step-by-step explanation:

Solve the inequality for b

-15b <= 45 divide both sides by -15, since you're dividing by a negative number switch the direction of the sign.

b >= -3

So, your number line is all values of b greater than or equal to -3. Since it is including -3, the circle will be filled and increase to the positive.
