Create a histogram of this data.

To create a histogram, hover over each age range on the x-axis. Then click and drag up to plot the data.

Answers

Answer:

Refer to image

Step-by-step explanation:

When creating a histogram it is best to create a range for the different variables that are available.

So for the sake of covering all the possible ranges from 1 - 22, let's divide it into 5 categories.

0 - 5

6 - 10

11 - 15

16 - 20

21 - 25

Now that we have set ranges for the different variables, we then find the frequencies.

0 - 5 : 3

6 - 10 : 2

11 - 15 : 3

16 - 20 : 1

21 - 25 : 3

Now that we have all the values we can then create our histogram

CBD is 120 degrees

Step-by-step explanation:

x=30

4x30+30+30=180

Answer: 120°

Step-by-step explanation:

x + 4x + x = 180° (Since the sum of a straight line is 180°)

6x = 180°

x = 30°

To find the angle of 4x, we need to multiply 4 x 30°

Find the length of all segments in the triangle
Find LA, AE, SL

Answers

AE= 6.93 - 4.63 = 2.3 cm

LA: a2 + b2 = c2
(3.26)2 + (2.3)2 = LA2
10.63 + 5.29 = LA2
15.92 = LA2
sqrt 15.92 = LA
So, LA= 3.98 cm

LS: a2 + b2 = c2
(3.98)2 + (b)2 = (6.93)2
b = sqrt (6.93)2 - (3.98)2
So, LS = 5.67 cm

Given P(A)=0.64P(A)=0.64, P(B)=0.4P(B)=0.4 and P(A\cap B)=0.356P(A∩B)=0.356, find the value of P(A\cup B)P(A∪B), rounding to the nearest thousandth, if necessary.

Answers

Answer:

Step-by-step explanation:

P(A U B) = P (A) + P (B) - P (A and B)

= 0.64 + 0.4 - 0.356

= 0.684

The value of P(A∪B) is 0.684

What is probability?

Probabilities are used to determine the chances of events

The given parameters are:

P(A)=0.64,

P(B)=0.4

P(A∩B)=0.356

To find the value of P(A∪B), we make use of the following formula

P(A∪B) = P(A) + P(B) - P(A∩B)

So, we have:

P(A∪B) = 0.64 + 0.4 - 0.356

Evaluate the expression

P(A∪B) = 0.684

Hence, the value of P(A∪B) is 0.684

which of these figures has rotational symmetry?

Answers

Answer: Choice C

We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.

The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. The correct option is C.

What is Rotational Symmetry?

The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. When turned 180 degrees or with specific angles, clockwise or anticlockwise, many geometrical forms appear to be symmetrical. Examples include squares, circles, hexagons, and more.

The shape that has a rotational symmetry is option C, which is a parallelogram.

Hence, the correct option is C.

What is a trinomial?

A trinomial is an algebraic expression that has three non-zero terms and has more than one variable in the expression.

Given is a trinomial, 2x²-16x+30

On factorizing,

= 2x²-16x+30

= 2x²-10x-6x+30

= 2x(x-5)-6(x-5)

= (2x-6)(x-5)

= 2(x-6)(x-5)

Hence, the factors for the given trinomial is 2(x-6)(x-5)

why is the order you use to name polygons important when writing a congruency statement?

Answers

Answer:

When stating that two triangles are congruent, use a congruence statement. The order of the letters is very important, as corresponding parts must be written in the same order.
