The Dot Plot Shows The Ages Of Students, In Years, On A Basketball Team. Each Dot Represents 1 Student.

Answers

Answer 1

Answer:

Mode = 15

Mean = 12.8

Step-by-step explanation:

Given the data :

As obtained form the dot plot :

X : 11, 11, 11, 12, 12, 12, 13, 13, 13, 13, 14, 14, 15, 15

The mean of the data:

Mean = ΣX / n

Mean = 179 / 13

Mean = 12.785 = 12.8 years

Mode = most frequently occurring value = 15

3. In a triangle, two angles have measures of 45°
and 85. What is the measure of the third angle in
this triangle?

Answers

Answer:

Triangles always have 180°, split in some manner between the three angles. With two of the three angles given, you can set up a relatively simple equation, where the third angle is assigned to the variable x:

45°+85°+x=180°

130°+x=180°

x=50°

Find the length of side x in simplest radical form with a rational denominator.
60°
V3
30°
X

Answers

Answer:

4√3/3

Step-by-step explanation:

Find the diagram attached below

Considering angle 60°

Opposite side = 2

Hypotenuse = x

Using the SOH CAH TOA identity

sin theta  = opposite/hypotenuse

sin 60 = 2/x

x = 2/sin60

x = 2/(√3/2)

x = 2 * 2/√3

x = 4/√3

Rationalize

x = 4/√3 * √3/√3

x = 4√3/3

Hence the value of x in its simplest form is x = 4√3/3

solve and graph: 7x-6>22
(pls explain your answer, im confused on this)​

Answers

Answer:

x>4

Step-by-step explanation:

Solving an inequality is very similar to solving an equation:

Given: 7x-6>22

Add 6 to both sides: 7x>28

Divide both side by 7: x>4

x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

How many onto functions are there from a set with three elements to a set with eight elements?

Answers

Answer:

0 onto functions

Step-by-step explanation:

Let the sets be [tex]A\ and\ B[/tex] such that:

[tex]n(A) = 3[/tex]

[tex]n(B) = 8[/tex]

Required

The number of onto functions

The condition for onto functions is:

For there to be an onto function from set A to set B, the number of elements of B must be less than the elements in set A

Since n(B) > n(A) i.e. 8 > 3

Then, there can't be onto functions from A to B

m[tex]\angle{LMN[/tex] is 108°.

What is an angle ?

To form an angle we need at least two rays with one common endpoint this is also known as vertex of the angle.

There are many types of angles.For example - Acute angle, Obtuse angle, Right angle, complementary angle, Supplementary angle.

The most common unit for measuring an angle is in degrees and in radians,Where 1 rad = 180°.

According to the given question.

[tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex] are given they are 85° and 23° respectively.

From the given diagram we can observe that [tex]\angle{LMN[/tex] is sum of the angles [tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex].

∴ [tex]\angle{LMP[/tex] + [tex]\angle{PMN[/tex] = [tex]\angle{LMN[/tex]

     85° + 23° = 108°.

So, [tex]\angle{LMN[/tex] = 108°.
