Fill in the missing num W + 2 7 9 2​

By using the principles of fractions, we can find out that the models represent the problem 3/4 × 3.

A number that represents a percentage of a whole serves as the mathematical representation of a fraction. Fractions can be thought of as any number, any amount, or a portion of an object.

A pizza that has been cut into eight equal pieces. The notation 1/8, which denotes that we are speaking of one portion out of 8 equally sized portions, can be used to refer to a single portion of the pizza.

It indicates one equal part in eight. Furthermore, it can be written as: 1/8

It will be written as 2/8 if we choose to have 2 portions of the pizza. Similar to how we would write 6/8 as a fraction if we were referring to 6 portions of this pizza.

Now here in the question, 3 parts are selected out of 4.

So that suggests it is 3/4.

As there are 3 circular models, so the representation will be as:

3/4 × 3.

Answer:

163

Step-by-step explanation:

10(10)+9(7)=

100+63=163

Answer:

163

Step-by-step explanation:

If z=10 and w=7.

10z+9w [writing the equation again for reference purposes]

10(10) + 9(7) [we substitute each variable with its defined value]

100 + 9(7) [we multiply 10 and 10, aka 10 and z]

100 + 63 [we multiple 9 and 7, aka 9 and w]

163 [we add 100 and 63 to get our final answer]

Answer:

(a) [tex]\hat y=69.04-0.083\cdot x[/tex]

(b) D. For every unit increase in commute​ time, the index score falls by 0.083​, on average.

Step-by-step explanation:

(a)

Form the least-squares regression line using Excel as follows:

Go to Data → Data Analysis → Regression

A dialog box will open.

Select the X and Y variable.

Press Ok.

The regression output is attached below.

The least-squares regression line is:

[tex]\hat y=69.04-0.083\cdot x[/tex]

(b)

The slope of a regression line is the average rate of change in the dependent variable (y) with 1 unit change in the independent variable (x).

Here the slope value is -0.083. This value implies that with 1 minute change in the commute times the Well-Being Index​ Score falls by 0.083 units.

The intercept of a regression line is the average value of the dependent variable (y) when the independent variable (x) value is 0.

Here, the intercept value is 69.04. This value implies that for a person with commute time 0, their Well-Being Index​ Score is 69.04.

The correct option is:

D. For every unit increase in commute​ time, the index score falls by 0.083​, on average.

Answer:

[tex]Ratio = 11:13[/tex]

Step-by-step explanation:

Represent Amar age with x

Represent Kabir age with y

So, we have:

Presently

[tex]x : y = 3 : 4[/tex]

After 4 years

[tex]x + 4 : y + 4 = 7 : 9[/tex]

Simplify both ratios:

[tex]x : y = 3 : 4[/tex]

[tex]\frac{x}{y} = \frac{3}{4}[/tex]

Cross Multiply

[tex]4x = 3y[/tex]

Make x the subject

[tex]x = \frac{3}{4}y[/tex]

[tex]x + 4 : y + 4 = 7 : 9[/tex]

[tex]\frac{x + 4}{y + 4} = \frac{7}{9}[/tex]

Cross Multiply

[tex]7(y+4) = 9(x+4)[/tex]

Open Brackets

[tex]7y + 28 = 9x + 36[/tex]

Collect Like Terms

[tex]9x = 7y + 28 - 36[/tex]

[tex]9x = 7y -8[/tex]

Substitute [tex]\frac{3}{4}y[/tex] for x in [tex]9x = 7y -8[/tex]

[tex]9(\frac{3}{4}y) = 7y - 8[/tex]

[tex]\frac{27}{4}y = 7y - 8[/tex]

[tex]6.75y = 7y - 8[/tex]

[tex]6.75y - 7y = - 8[/tex]

[tex]-0.25y = - 8[/tex]

[tex]y = -8/-0.25[/tex]

[tex]y = 32[/tex]

Substitute 32 for y in [tex]x = \frac{3}{4}y[/tex]

[tex]x = \frac{3}{4} * 32[/tex]

[tex]x = \frac{3* 32}{4}[/tex]

[tex]x = \frac{96}{4}[/tex]

[tex]x = 24[/tex]

So, in 20 years time, the ratio of the ages would be:

[tex]x + 20 : y + 20[/tex]

This gives

[tex]24 + 20 : 32 + 20[/tex]

[tex]44 : 52[/tex]

Divide by 4

[tex]44/4:52/4[/tex]

[tex]11:13[/tex]

Hence, the Ratio is

[tex]Ratio = 11:13[/tex]

Answer:

y = x - 3

if you plug in the numbers from the table, it checks out.

y = x - 3

0 = 3 - 3

0 = 0

y = x - 3

1 = 4 - 3

1 = 1

y = x - 3

2 = 5 - 3

2 = 2

and so on

b = 387

Step-by-step explanation:

1057 - 670 = 387

First isolate B by putting the 670 to the other side of the equal sign. However, in order for the equation to remain equal, you must subtract 670 from both sides.

1057 - 670 = B + 670 - 670

387 = B

Answer:

Step-by-step explanation:

When Maurice works 15hrs, he makes $150.

So first you have to find out how much money he makes each hour.

To do this you do :

Money earnt divided by hour many hours he worked.

Money made per hour = [tex]\frac{150}{15}[/tex]  = $10

So since Maurice makes $10 every hour,

If her works 25 hours, it will be $10 x 25 = ?

Answer:

D, R: {11, -4, -29}

Step-by-step explanation:

According to the given set of domains, the corresponding range is found by substituting the x values into the equation and solving for y.

i.e {-2} -> 5x + y = 1, -10 + y = 1, y = 11

{1} -> 5x + y = 1, 5 + y = 1, y = -4

{6} -> 5x + y = 1, 30 + y = 1, y = -29

Answer:

The solution is [tex]\displaystyle x=1\pm \sqrt{47}[/tex]. Fourth option

Explanation:

Solve for x:

[tex]2x^2+3x-7=x^2+5x+39[/tex]

Move all the terms from the right to the left side of the equation, a zero in the right side:

[tex]2x^2+3x-7-x^2-5x-39=0[/tex]

Join all like terms:

[tex]x^2-2x-46=0[/tex]

The general form of the quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Solve the quadratic equation by using the formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

In our equation: a=1, b=-2, c=-46

Substituting into the formula:

[tex]\displaystyle x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-46)}}{2(1)}[/tex]

[tex]\displaystyle x=\frac{2\pm \sqrt{4+184}}{2}[/tex]

[tex]\displaystyle x=\frac{2\pm \sqrt{188}}{2}[/tex]

Since 188=4*47

[tex]\displaystyle x=\frac{2\pm \sqrt{4*47}}{2}[/tex]

Take the square root of 4:

[tex]\displaystyle x=\frac{2\pm 2\sqrt{47}}{2}[/tex]

Divide by 2:

[tex]\displaystyle x=1\pm \sqrt{47}[/tex]

First option: Incorrect. The answer does not match

Third option: Incorrect. The answer does not match

Fourth option: Correct. The answer matches exactly this option

[tex]y = ab^{x} [/tex]

[tex]y = 3 \times {4}^{x} [/tex]

"a" is the initial amount (3), and "b" is the growth factor (4).

To find "b" plug in the knowns into the exponential function equation and solve.

[tex]y = ab^{x} [/tex]

[tex]48 = 3 \times {b}^{2} [/tex]

[tex]16 = {b}^{2} [/tex]

[tex] \sqrt{16} = b[/tex]
