Option D is correct, tossing a coin 3 times is a simple event.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
A simple event is a single outcome or result of an experiment or probability experiment.
In option D, the simple event is tossing a coin once and getting either a heads or a tails.
Since the event is repeated three times, there are a total of 8 possible outcomes (HHH, HHT, HTH, THH, TTH, THT, HTT, TTT).
However, each of these outcomes is made up of three simple events, which are the individual tosses of the coin.
In options A and B, there are multiple events happening, each of which has multiple possible outcomes, so they do not describe a simple event. In option C, there is only one event happening, but there are multiple possible outcomes of that event, so it also does not describe a simple event.
Hence, Option D is correct, tossing a coin 3 times is a simple event.

Which three types of transformations result in congruent shapes? Question 8 options: A) Reflection, rotation, translation B) Reflection, translation, dilation C) Reflection, dilation, rotation D) Rotation, dilation, translation
Answer: A
Step-by-step explanation:
Answer:
A. Reflection, rotation, translation
Step-by-step explanation:
Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent. Explore and discuss the examples of transformations below with your child.

The measure of the trigonometric relation cos 60° = 1/2
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the trigonometric relation be represented as A
Now , the value of A is
A = cos 60°
And , cos θ = adjacent / hypotenuse
So , cos 60° = 1/2
Hence , the measure of cos 60° = 1/2

A phone company offers two monthly plans. Plan A costs $21 plus an additional $0.09 for each minute of calls. Plan B has no initial fee but costs $0.13 for each minute of calls.
For what amount of calling do the two plans cost the same?
minutes
What is the cost when the two plans cost the same?
$
Answer:
525; $68.25
Step-by-step explanation:
21+.09x=.13x
x=525
21+.09(525)=68.25
.13(525)=68.25
The answers are :
A) The amount of calling for which the two plans cost the same will be 525 minutes.
B) The cost when two plans cost the same amount is $68.25.
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
A)
Let's assume the amount of calling is x for which the two plans cost the same.
So , the algebraic expression can be written as ;
Plan A = Plan B
or
21 + (0.09 × x) = 0 + (0.13 × x)
Solving this we will get amount of calling for which the two plans cost the same as :
21 = 0.13x - 0.09x
0.04x = 21
x = 525 minutes
B)
Now , the cost when two plans cost the same amount :
Plan A = 21 + (0.09 × 525) = 21 + 47.25 = $68.25
or
Plan A = Plan B = $68.25
Therefore , the answers are :
A) The amount of calling for which the two plans cost the same will be 525 minutes.
B) The cost when two plans cost the same amount is $68.25.

Given the following information about events A, B and C determine which pairs of events, if any, are independent and which are mutually exclusive.
P(A) = 0.26, P(A|B) = 0.26, P(B) = 0.5, P(B|C) = 0, P(C)=0.45, P(C|A) =0.26.
Select all that apply:
a. Are B and C independent?
b. Are A and C mutually exclusive?
c. Are A and B independent?
d. Are A and B mutually exclusive?
Answer:
a. Are B and C independent? NO
b. Are A and C mutually exclusive? NO
c. Are A and B independent? YES
d. Are A and B mutually exclusive? NO
Step-by-step explanation:
Given the data in the question;
P(A|B) = 0.26 P(A) [ A and B are independent ]
P(B|C) = 0 [ B and C are mutually exclusive ]
P(C/A) = 0.26 ≠ P(C)
hence, [A and C are neither independent nor mutually Exclusive]
Therefore;
a. Are B and C independent? NO
b. Are A and C mutually exclusive? NO
c. Are A and B independent? YES
d. Are A and B mutually exclusive? NO
Find the measure if two complementary angles if the measure of the larger angle is 10 more than the measure of the smaller angle.
Answer: 50° and 40°
Step-by-step explanation:
Complementary angles add up to 90°
Smaller angle - x
Larger angle - 10 + x
10 + x + x = 90
10 + 2x = 90
Subtract 10 from both sides
2x = 80
Divide both sides by 2
x = 40
Larger angle - 10 + x
10 + 40 = 50
The measure of the smaller angle is 40° and the measure of the larger angle is 50°

Step-by-step explanation:
I'll go over #7 and you should be able to do the rest.
Slope intercept form general equation is:
y = mx + b
I bolded the value you need to change/find.
m is the slope
b is the y-intercept
You can calculate m using:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
you're given (-4,-4) and (0,5) so y₂=5, y₁=-4, x₂=0, x₁=-4
[tex]m=\frac{5-(-4)}{0-(-4)}=9/4[/tex]
Plug your value into the point-slope formula.
[tex]y = m(x-x_1)+y_1[/tex]
[tex]y = (9/4)(x-(-4))+(-4)[/tex] simplify it
[tex]y= 9/4x+5[/tex] the simplified form is the slope-intercept formula

Kelly,Marvin and Indhu saved $100 altogether.Kelly saved $16 more than Indhu .Marvin saved twice the amount Indhu saved. How much did kelly save?
Answer:
$37
Step-by-step explanation:
Let $x be the amount Kelly saved.
Kelly saved $x.
Indhu saved $(x-16). (Kelly saved $16 more than Indhu)
Marvin saved $2(x-16). (Marvin saved twice the amount Indhu saved)
They saved $100 together.
Therefore we could set up an equation.
x+(x-16)+2(x-16)=100
x+x-16+2x-32=100
4x=148
x=37
Therefore Kelly saved $37.
