the sum of 10 observation is 110 then the mean is
A)11
B)10
C)7
D)5​

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

In the Triangle BCD, Angle B is 90° since tangent and radius are perpendicular to one another.

Now, let's find Angle C using Angle sum property of a triangle.

[tex]\qquad \tt \dashrightarrow \:\angle C + \angle B + \angle D = 180[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C + 90 + 45= 180[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C + 135= 180[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C= 180 - 135[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C= 45 \degree[/tex]

Now, we know that Angle made by an arc on the centre is twice the Angle made by same arc on boundary of circle, hence we can infer that :

[tex]\qquad \tt \dashrightarrow \:2\angle C = 10x[/tex]

[tex]\qquad \tt \dashrightarrow \:10x = 2 \times 45[/tex]

[tex]\qquad \tt \dashrightarrow \:x = 90 \div 10[/tex]

[tex]\qquad \tt \dashrightarrow \:x = 9[/tex]

So, the required value of x is 9

The value that will have the most dots displayed in the dot plot created for the data set is: C. 5

To create a dot plot, construct a horizontal line to label the values in the data set, then use dots to indicate the frequency in which each of the data points appear.

Given the data set:

2, 5, 5, 1, 4, 6, 2, 3, 5, 6, 3, 1, 4, 6, 1, 5

1 will have 3 dots

2 - 2 dots

3 - 2 dots

4 - 2 dots

5 - 4 dots

6 - 3 dots

Thus, the value with the most dots displayed would be: 5.

Answer:

I can t see it

Step-by-step explanation:

Formula for the circumference of a circle = pi x 2 x radius

Circumference = 3

pi = 3.14

radius = r

---To find the radius, we will need to solve for it. Start by plugging in what we know.

3 = 3.14 x 2 x r

---Simplify by multiplying 3.14 by 2

3 = 6.28 x r

---Divide both sides by 6.28 to solve for r

r = 3 / 6.28 = 0.4777

---Round the decimal to the nearest tenth

r = 0.5

Hope this helps!

r=0.5

The square MATH has equal side lengths MA, TH, AT and HM

Hanna's claim is correct because

The coordinate points are given as:

M(1, 2), A(-5, 3), T(-6,-3), and H(0,- 4).

Calculate the side lengths of the square using the following distance formula

d = √[(x2 - x1)^2 + (y2 - y1)^2]

So, we have:

MA = √[(1 + 5)^2 + (2 - 3)^2] = √37

AT = √[(-5 + 6)^2 + (3 + 3)^2] = √37

TH = √[(-6 + 0)^2 + (-3 + 4)^2] = √37

HM = √[(0 - 1)^2 + (-4 - 2)^2] = √37

The side lengths are equal.

Next, we calculate the slopes using:

m =(y2 - y1)/(x2 - x1)

So, we have:

MA = (2-3)/(1+5) = -1/6

AT = (3+3)/(-5+6) = 6

TH = (-3+4)/(-6+0) = -1/6

HM = (-4-2)/(0-1) = 6

See that opposite sides have the same slope

i.e MA = TH and AT = HM

And adjacent sides have their slopes to be opposite reciprocals

i.e. MA = -1/AT and TH = -1/HM

The calculated distances and slopes implies that Hanna's claim is correct

The solution of the inequality 2(4x - 3) ≥ -3(3x) + 5x is true for all x such that its a real number bigger or equal to 0.5 (Option A: x ≥ 0.5)

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

The considered inequality is:

[tex]2(4x - 3) \geq -3(3x) + 5x[/tex]

Simplifying its both sides, we get:

[tex]2(4x - 3) \geq -3(3x) + 5x\\8x-6\geq -9x + 5x\\8x-6 \geq -4x[/tex]

Adding 4x on both the sides, we get:

[tex]8x-6+4x \geq -4x + 4x\\(8+4)x - 6 \geq 0\\12x -6 \geq 0\\[/tex]

Adding 6 on both the sides, and dividing by 12, we get:

[tex]12x-6 +6 \geq 0+6\\12x \geq 6\\12x/12 \geq 6/12\\x \geq 0.5[/tex]

(some operations like addition, subtraction, multiplication by positive real number or division by positive real number keeps the inequality relation unaltered. With the use of such operations, here we tried to get x on one side, and constants on other side).

Thus, the considered inequality is true for all the values of x which are real numbers bigger or equal to 0.5 (Option A: x ≥ 0.5)

Find the coordinates of the point after dilation:

Answer: A) 2.4 ÷ 6

Step-by-step explanation:

      To answer this problem, we need to find the original whole and what it is being divided by.

[] The whole is 2.4 because we see two wholes shaded in, and 4 columns shaded in. For this model, it represents 2.4

[] It is being divided into 6 parts. This is shown with the white numbers and the thicker lines

      We can also check with math, 2.4 divided by 6 is 0.4 so it "checks out."

      This model represents the expression A) 2.4 ÷ 6.

Answer:

The answer is 12

Step-by-step explanation:

look under the home tab and look at 5-10. There's the answer

The percent of children who are between the ages 5 and 10 will have their birthday party at home is 10.91%.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Percentage is usually denoted by the symbol '%'.

Given that,

There are total of 325 children in different ages who have their birthday party in different ways.

Number of children in between the ages 5 and 10 = 110

Number of children of the ages 5-10 who have their birthday party at home = 12

In order to find the percentage, divide part with the whole.

Percentage = 12 / 110 = 0.1091

Percentage is 10.91%

Hence the required percentage is 10.91%.
