Nancy decides to roll a die three times. What's the probability that she will roll all even numbers?
Answer:
1/8
Step-by-step explanation:
The probability of rolling an even number on one roll is 3/6 = 1/2. Assuming the rolls are independent, the probability of rolling an even number 3 times is ...
(1/2)(1/2)(1/2) = 1/8
The probability that Nancy rolls all even numbers in 3 rolls is 1/8.
The probability that she will roll all even numbers is 1/8.
It should be noted that there are 6 numbers in one roll of a dice. Therefore, there are 3 even numbers and 3 odd numbers.
The probability of getting even numbers in one roll will be:
= 3/6 = 1/2
The probability that she will roll all even numbers will be:
= 1/2 × 1/2 × 1/2
= 1/8

The city planning committee wants one tree planted every 20 ft along Dayton Ave. if the perimeter of the plot of land is 234 ft about how many trees will be planted. explain. 12 is an incorrect answer.
Answer:
2 trees
Step-by-step explanation:
Since the city is planting a tree every 20 feet across Dayton Avenue, then we need to find the length of the side that is on Dayton Avenue.
We are missing 3 sides to this. But it's extremely important to note that the side adjacent to Dayton Avenue is the same length as the other missing two sides combined. This is because both of these lengths contain the 1 feather and 2 feather mark - these signify congruence.
This means that the side lengths of both of them combined will be [tex]234-52-68=114[/tex]
This means the side adjacent to Dayton Avenue is
[tex]114\div2=57[/tex] feet long.
Now that we know that the side is 57 feet long, we have to divide this by 20, as a tree is being placed every 20 feet. If we get a decimal, we will have to round down because it gets planted only, and only if, 20 more feet has been accomplished. If we are a fraction of the way there, a tree doesn't get planted.
[tex]57\div20=2.85[/tex]
Rounding down gets us 2.
Hope this helped!
The number of trees to be planted is 2 trees
The process of arriving at the above number of trees is as follows;
The given parameter are;
The perimeter of the plot of land adjacent to Dayton Avenue = 234 ft.
The perimeter has two pair of unknown lengths sides marked with equal lengths symbols
One length each of the two congruent pairs form a linear pair adjacent to the road
The length of one of the other side = 52 feet
The length of the fifth side of the perimeter = 68 ft.
Method;
Let, x, and y represent the lengths of the congruent pairs, we have;
52 ft. + 68 ft. + 2·x + 2·y = 234 ft.
2·x + 2·y = 234 ft. - (52 ft. + 68 ft.) = 114 ft.
The length of the linear pair forming the side of the perimeter adjacent to the road, x + y = 114 ft./2 = 57 ft.
The number of trees planted every 20 ft. = 1 tree
The number of trees, n, that can be planted along the perimeter of the plot of land adjacent to Dayton Avenue which is 57 ft. long is therefore;
n = 57 ft./(20 ft./Tree)
∴ n = 57/20 Trees = 2.85 trees
The number of trees that can actually be planted by the owners of the plot
of land is given by rounding down to the next whole number, given that the
the information is statistical analysis which gives;
n ≈ 2 Trees
The number of trees to be planted = 2 trees

what are the coefficients of 8+5x-y
Answer:The coefficients are the numbers that multiply the variables or letters. Thus in 5x + y - 7, 5 is a coefficient. It is the coefficient in the term 5x. Also the term y can be thought of as 1y so 1 is also a coefficient.A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. ... Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.First of all, coefficent means the number standing in front of a variable.
So, according to the expression, 2 - 5x - 4 + 8, the coefficient is -5.
Why? because it stands in front of the variable.

A Queensland toad travels 10 m/day. How far will it travel in 5 hours?
Answer:
2.08
Step-by-step explanation:
10/x = 24/5
50 = 24 x
x = 50 / 24
x = 2.08 m
This answer is rounded to the nearest hundredth.
Answer:
2.083 meters
Step-by-step explanation:
10/24 = 0.416
if the toad travels 10 meters in a day then in order to get how many meters the toad travels in an hour you have to divide that number (10) by 24 which is the number of hours in a day
0.416 × 5 = 2.083
After that you just have to multiply the number of meter that the toad travels in an hour by 5 hours which will get you 2.083 meters

Samantha is wall papering her bedroom and wants to make sure that she bought enough wall paper. Each wall in her room measures 10 feet by 11 feet. How many rolls of wall paper will Samantha need if each roll covers a total of 25 square feet.
Answer:
4.4 rolls of wallpaper
Step-by-step explanation:
Dimensions of Samantha's room= 10 feet by 11 feet
Length= 11 feet
Width= 10 feet
Area of Samantha's room= Length × width
= 11 feet × 10 feet
= 110 square feet
Each roll covers a total of 25 square feet
Total rolls of wallpaper = Area of the room / Area covered by each roll
=110 square feet / 25 square feet
= 4 10/25
= 4 2/5
= 4.4 rolls

Function ____ has the larger maximum.
(Put 1 or 2 in the blank space)
Answer:
Answer:
Function 1 written in vertex form is f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 - (-1) = -(x - 4)^2 + 1
Therefore, vertex = (4, 1)
Function 2 written in vertex form is f(x) = -x^2 + 4x + 1 = -(x^2 - 4x - 1) = -(x^2 - 4x + 4 - 1 - 4) = -(x - 2)^2 - (-5) = -(x - 2)^2 + 5
Therefore vertex = (2, 5)
Function 1 has a maximum at y = 1 and function 2 has a maximum at y = 5. Therefore, function 2 has a larger maximum.
