For the coin: 2 possibilities, either head or tail. So probability of head is 1/2.
For the cube (assuming numbers are 1 to 6): 6 possibilities (1 2 3 4 5 6). We have 3 odd numbers, so probability of odd number is 3/6=1/2.
You want both head and an odd number, so you multiply the 2 probabilities: 1/2×1/2=1/4.
So the answer is 1/4.
You can use a tree to better understand probabilities.

Sarah has a part time job working as a line cook. She earns $56 a night plus 5% of the tips.
A- write an equation for Sarah’s total earnings, E dollars, when the tips are t dollars.
B- what will Sarah earn when the tips are $350? Explain your strategy
C- what were the nightly tips when Sarah earned $81? Explain your strategy
Thank you :]
Answer:
A: E = 0.05t +56
B: $73.50
C: $60.05
Step-by-step explanation:
A) I'll just explain the equation in one go
Equation: E = 0.05t + 56
0.05 - This is meant to represent the 5% of tips
5% = 5/100
5/100 = 0.05
56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%
B+C) Since we already have the equation set up, we just need to plug in the variable, t.
B) E = 0.05(350) + 56
= 17.5 + 56
= 73.50
C) E = 0.05(81) + 56
= 4.05 + 56
= 60.05

Answer:
y+2, y+4
Step-by-step explanation:
Consecutive odd integers differ by 2.
The next two are ...
y+2
y+4

Additional comment
You may find it simplifies the math in consecutive integer problems if you let the variable represent the middle one. If y is the middle one, the three odd integers are represented by y-2, y, y+2.

You are offered a 30--day trial period at your dream job. However, the owner of the company is a little unusual so the pay options are non-traditional. They offer you two different pay options for the 30 days:
Option 1: You make $60,000 per day.
Option 2: You make 1 penny the first day, 2 pennies the second day, 4 pennies the third day, 8 pennies the fourth day, etc.
Which is $5,368,709.12 after 30 days of working.
Answer:
The question is not complete but from the flow of thought, the question seems to be about what your choice will be between option 1 and option 2.
The correct answer is
option 2
Step-by-step explanation:
The question is asking you to choose an option that pays more after 30 days. In other to determine the more beneficial option, we will compare both options and select the one that pays more. This is done as follows:
option 1: $60,000 per day, after 30 days =
60,000 × 30 = $1,800,000
option 2 = $5,368,709.12 after 30 days
From the total amounts after 30 days of the two options listed above, option 2 is higher than option 1 by $3,568,709. Therefore, option 2 is a better choice.
A horizontal translation is used to move quadrilateral W XYZ onto quadrilateral
W XYZ.
Use the drop-down menus to describe the horizontal translation used.
Answer:
Quadrilateral WXYZ is translated 10 units to the left
Step-by-step explanation:
Translation of Shapes in the Plane
The translation is a type of rigid transformation where all the coordinates of the vertices that form the shape are shifted by the same number of units both vertically and horizontally.
The quadrilateral WXYZ has coordinates:
W(2,-3) X(7,-3) Y(6,-7) Z(1,-7)
The quadrilateral W'X'Y'Z' has coordinates:
W'(-8,-3) X'(-3,-3) Y'(-4,-7) Z'(-9,-7)
It can be noted that all the x-coordinates of the vertices are shifted by 10 units to the left.
Answer:
Quadrilateral WXYZ is translated 10 units to the left.

There will be 340 people on a school trip to Washington, D.C. Each school bus holds
45 people, and all the buses will be filled except for the last bus. How many school
buses will be needed and how many people will be on the last bus?
A. 8 buses with 25 people on the last bus
B. 7 buses with 25 people on the last bus
C. 8 buses with 35 people on the last bus
D. 8 buses with 45 people on the last bus
Step-by-step explanation:
340 people ÷ 45 per bus = number of busses.
340÷45=7.555555555
7 full busses
45 people × 7 busses = 315 people with seats
340 people total - 315 people with seats = 25 people left
answer A. 8 busses with 25 on last bus.
There will be 8 busses needed with 25 on last bus. so option A is correct.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given; There will be 340 people on a school trip to Washington, D.C.
Each school bus holds 45 people, and all the buses will be filled except for the last bus.
So, 340 people ÷ 45 per bus = number of busses.
340÷45 = 7.555555555
The numebr of buses = 7 full busses
Then, 45 people × 7 busses = 315 people with seats
340 people total - 315 people with seats = 25 people left
Hence, There will be 8 busses needed with 25 on last bus. so option A is correct.

There are 6 bookshelf's that hold 72 books per shelf. if 1/3 of the total number of books are non-fiction,how many fiction books are there.
Answer:
288 fiction books
Step-by-step explanation:
If the other 2/3 are fiction, then I believe that you would multiply 72 by 6 then divide by 3 or multiply by 1/3 giving you 144. Multiply 144 by 2 and you should get 288, but this is if there are only fiction and non fiction. Sorry if this is wrong..

Walt's haircut costs $32. He leaves a 15% tip. How much does he pay for the haircut, including the tip?
Answer:
Walt pays $47
Step-by-step explanation:
If Walt pays $32 for his haircut, and 15% is his tip,
We know here that in percentages, 15% = 15/100, which equals $15
Then, you would simply do 32 + 15
32 + 15 = 47.
Walt pays $47 for his haircut

A cup of coffee contains 140 mg of caffeine. If caffeine leaves the body at 10% per hour, how long will it
take for half of the caffeine to be eliminated from one's body?
Answer: 5 hours
Step-by-step explanation:
If 10% of 140 is 14. And if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from ones body, but for half of it to leave it would take 5.
It takes 5 hours to eliminate half of the caffeine from one's body.
Given that, a cup of coffee contains 140 mg of caffeine.
What is the percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Now, 10% of 140
=0.1×140=14 mg
If 10% of 140 is 14 and if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from one's body, but for half of it to leave it would take 5 hours.
Therefore, it takes 5 hours to eliminate half of the caffeine from one's body.

Since the sum of the angles in a quadrilateral is 360 degrees then the angle D is 50 degrees.
What is a quadrilateral?A quadrilateral is a four sided figure. Examples of quadrilaterals include; square, parallelogram, rectangle, kite etc.
The sum of angles in a quadrilateral is 360 degree hence;
A + B + C + D = 360 (sum of angles in a quadrilateral)
128 + 126 + 54 + D = 360
D = 360 - ( 128 + 126 + 54)
