Answer:

119

explained:  you would have to take all the numbers and line them from greatest to smallest, for example 100,103,103,105,106,112,115,106,112,115,117,121,122,122,128,129,141,141,141

and since your median is your middle number, and you have an even set of numbers that means you will have two medians 117 and 121. You add them up and divide by two which equals 119.

Hope this helps!

Answer:

2

Step-by-step explanation:

If the tenth place has a number under 5, round down. (2)

If the tenth place is 5 or more, roundup. (3)

The solution for the number 2.42 rounded to the nearest tenth is 2.4

Used the concept of rounding numbers which states that,

When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.

1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

Here, the question said the nearest tenth,

The number to round is 2.42

Clearly, the number 2 placed in the hundredth place is less than 5, so round the number down.

That is 2.42 ≈ 2.4

Therefore, the solution is 2.4

Answer: The temperature on the 5th day is -14 degrees.

Step-by-step explanation:

If we have a set of N values:

{x₁, x₂, x₃, ..., xₙ}

The mean value of this set is:

M = (x₁ + x₂ + ... + xₙ)/N

Now, we know that the mean temperature for the first 4 days of January is -4°

Then if the temperatures for the first four days are {T₁, T₂, T₃, T₄}

We have:

M₄ = (T₁ + T₂ + T₃ + T₄)/4 = -4°

Where we can replace (T₁ + T₂ + T₃ + T₄) by K

Then:

K/4 = -4°

K = -4°*4 = -16°

Is the sum of the temperatures for the first four days.

Now when we consider the first 5 days, the mean is -6°, and let's define T₅ as the temperature of the fifth day, then we get:

M₅ = -6° = (T₁ + T₂ + T₃ + T₄ + T₅)/5

And we know that:

(T₁ + T₂ + T₃ + T₄) = K = -16°

We can replace that in the above equation to get:

M₅ = (-16° + T₅)/5 = -6°

Now we can solve this for T₅

(-16° + T₅) = 5*(-6°) = -30°

T₅ = -30° + 16° = -14°

T₅ = -14°

The temperature on the 5th day is -14 degrees.

Step-by-step explanation:

Given Information :

Slope (m) = 6

y-intercept (b) = -5

Equation of a line :

y=mx+b

Where :

m = slope

b = y-intercept

So , with the given the information , the equation is :

[tex]y = 6x - 5[/tex]

Answer:

The coordinated points which quadrasects the line segments joining the points A and B are [tex]\left(-\frac{5}{4},4\right)[/tex], [tex]\left(\frac{1}{2}, 2 \right)[/tex] and [tex]\left(\frac{9}{4},0 \right)[/tex].

Step-by-step explanation:

Let [tex]A(x,y) =(-3,6)[/tex] and [tex]B(x,y) = (4,-2)[/tex], when the line segment is quadrasected, it means that segment is divided into four equal parts. The locations are determined by the following expressions:

[tex]\vec R_{1} = \vec A + \frac{1}{4}\cdot \overrightarrow{AB}[/tex] (1)

[tex]\vec R_{2} = \vec A + \frac{1}{2}\cdot \overrightarrow{AB}[/tex] (2)

[tex]\vec R_{3} = \vec A + \frac{3}{4}\cdot \overrightarrow{AB}[/tex] (3)

Where:

[tex]\overrightarrow{AB} = B(x,y)-A(x,y)[/tex]

[tex]\overrightarrow{AB} = (4,-2) - (-3,6)[/tex]

[tex]\overrightarrow{AB} = (7,-8)[/tex]

The coordinated points which quadrasects the line segments joining the points A and B are, respectively:

[tex]\vec R_{1} = (-3,6)+\frac{1}{4} \cdot (7,-8)[/tex]

[tex]\vec R_{1} = \left(-\frac{5}{4},4\right)[/tex]

[tex]\vec R_{2} = (-3,6)+\frac{1}{2} \cdot (7,-8)[/tex]

[tex]\vec R_{2} = \left(\frac{1}{2},2 \right)[/tex]

[tex]\vec R_{3} = (-3,6)+\frac{3}{4} \cdot (7,-8)[/tex]

[tex]\vec R_{3} = \left(\frac{9}{4},0\right)[/tex]

The coordinated points which quadrasects the line segments joining the points A and B are [tex]\left(-\frac{5}{4},4\right)[/tex], [tex]\left(\frac{1}{2}, 2 \right)[/tex] and [tex]\left(\frac{9}{4},0 \right)[/tex].

Answer:

Yes

Step-by-step explanation:

Use the completing the square method:

16(x^2-x)+4

=16((x-1/2)^2 - (1/2)^2)+4

=16((x-1/2)^2 - 1/4)+4

=16((x-1/2)^2) - 16/4 + 4

=16(x-1/2)^2

=4^2(x-1/2)^2

The product of two square is itself a square.

Answer:

x = 69 degrees

Step-by-step explanation:

x = 360 - 168 - 123

x = 69 degrees

Answer:

x = 69

168 + 123 + x = 360 (Sum of angle at a point)

291 + x = 360

x = 360 - 291

x = 69

Answer:

A = 42 - 80 B = 40 - 112

Step-by-step explanation:

I can answer Both A & B for you however C & D aren't very clear.

A:

Perimeter = 42cm

Area = 80cm Cubed

B:

Perimeter = 40cm

Area = 112cm Cubed

Calculations

In Question A, you are given all the measurements for the perimeter except, which is the line at the bottom. If we take what we already have been given.

10 + 8 + 4 + 4 + 3

We have 3 sides currently without a measurement, The Right side of the shape is 8, therefore the left must be the same, so that measurement is 8.

The small line creating the indent inside the shape must be 2, as we know the line at the top = 10cm. The line opposite it is must be 3 as the one opposite is 3cm.

Factoring those into our calculation:

10 + 8 + 8 + 4 + 4 + 3 + 3 + 2 = 42cm (Perimeter)

To find the Area you multiply the Height of the shape by the width.

Height = 8

Width = 10

8 x 10 = [tex]80cm^{2}[/tex] (Area)

In Question B, you are given all the measurements for the perimeter, so you would simply add them up again.

14 + 10 + 8 + 2 + 6 = 40cm (Perimeter)

To Calculate the Area as previously said you would multiply the width by height.

Height = 8cm

Width = 14

14 x 8 = [tex]112cm^{2}[/tex] (Area)

Hope this helps :)

Step-by-step explanation:

To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:

15/6 = 2.5

So your scale factor would be 2.5

And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)
