Which property would you use to simplify the following expression ? 3(y + 4)

Answer:

I think it's c. (76,108)

Step-by-step explanation:

because 76+108 = 184 - half of which is the mean

so c. is more likely

(76, 108) is the  range of possible values that best describes an estimate for the population mean.

The given sample mean is 92.

(80, 112)= 80+112/2

=96 which is not equal to 92.

(82, 114)=82+114/2

=98 which is not equal to 92.

(76, 108)= 76+108/2=92

The value 92 which is  equal to 92.

(78, 110)​ = 78+110/2

=94 which is not equal to 92.

(76, 108) is the  range of possible values that best describes an estimate for the population mean.

Answer: 1810 yards

Step-by-step explanation:

Given

Thomas ran 2 miles and Maria runs 50 yards more than half as far as Thomas

We know, 1 mile is equal to 1760 yards

So, Thomas run [tex]2\times 1760=3520\ \text{yards}[/tex]

half of its distance is 1760 yards

So, the distance covered by Maria is 1760+50=1810 yards

The probability the coin lands tails up exactly two times is 3/8

When a coin is flipped three times, the sample space is;

S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

In the above sample space, there are 3 occurrences where the coin lands tail up, out of the 8 occurrences.

So, the probability is:

P = 3/8

Hence, the probability the coin lands tails up exactly two times is 3/8

Step-by-step explanation:

56/7 = 8

56 is 8 times 7, so you need 8 times 3.

8 × 3 = 24

7:3 = 56:24

Answer:

24

Step-by-step explanation:

7 is being multiplied by 8 so just multiply 3 by 8 witch will give you 24

Answer:

x = 16

Step-by-step explanation:

Verticle angles are always congruent, so:

(8x + 15) = 143

Now, we can solve to isolate x:

8x + 15 - 15 = 143 - 15  (subtract 15 from both sides)

8x/8 = 128/8                (divide both sides by 8)

x = 16

You can always plug in the value of x to the original equation to check your answer:

8(16) + 15 = 143

Step-by-step explanation:

An equation is formed of two equal expressions. The graph can be used to solve the equation 2x-1=x+2 is the Top right one.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

The two of the given equations can be written as,

y = 2ˣ - 1

y = x + 2

If the two equations are now when plotted on the graph, it will be like the one shown below. Hence, the graph can be used to solve the equation 2x-1=x+2 is the Top right one.

Step-by-step explanation:

Given

y = 2(x - 3)² + 1

Rearrange making x the subject

Subtract 1 from both sides

y - 1 = 2(x - 3)² ( divide both sides by 2 )

[tex]\sqrt{\frac{y-1}{2} }[/tex] = (x - 3)² ( take the square root of both sides )

± [tex]\sqrt{\frac{y-1}{2} }[/tex] = x - 3 ( add 3 to both sides )

± [tex]\sqrt{\frac{y-1}{2} }[/tex] + 3 = x

Change y into terms of x with x being the inverse, that is

[tex]f^{-1}[/tex] (x) = ±[tex]\sqrt{\frac{x-1}{2} }[/tex] + 3

Answer:

a) The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].

b) The approximate distance between the high school and the stadium is 32 miles.

Step-by-step explanation:

a) The rest stop is located in the midpoint of the line segment between the high school and the stadium. Vectorially speaking, we use the following formula:

[tex]C(x,y) = \frac{1}{2}\cdot A(x,y) + \frac{1}{2}\cdot B(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Coordinates of the high school.

[tex]B(x,y)[/tex] - Coordinates of the stadium.

[tex]C(x,y)[/tex] - Coordinates of the rest stop.

If we know that [tex]A(x,y) = (3, 4)[/tex] and [tex]B(x,y) = (7,1)[/tex], then the coordinates of the rest stop are, respectively:

[tex]C(x,y) = \frac{1}{2}\cdot (3, 4) + \frac{1}{2}\cdot (7, 1)[/tex]

[tex]C(x,y) = \left(\frac{3}{2}, 2 \right) + \left(\frac{7}{2}, \frac{1}{2} \right)[/tex]

[tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex]

The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].

b) The approximate distance between the high school and the stadium ([tex]d[/tex]), in miles, is the product of the Length Equation of the Line Segment and the scale factor:

[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex] (2)

Where:

[tex]r[/tex] - Scale factor, in miles.

[tex]\Delta x[/tex], [tex]\Delta y[/tex] - Horizontal and vertical distances between the high school and the stadium, no unit.

If we know that [tex]r = 6.4\,mi[/tex], [tex]\Delta x = 4[/tex] and [tex]\Delta y = -3[/tex], then the distance between the high school and the stadium is:

[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex]

[tex]d = (6.4\,mi)\cdot \sqrt{4^{2}+(-3)^{2}}[/tex]

[tex]d = 32\,mi[/tex]

The approximate distance between the high school and the stadium is 32 miles.
