Answer:
Unlikely is probably the answer.
Step-by-step explanation:
Because Likely would mean above 50%
Equally likely and unlikely would be (equally) so 50% exact.
The last option seems wrong.
So Unlikely makes the most sense

use the expression 6.3×15÷3±6.8-28.09
to create an expression that includes a
set of parentheses so that the value of
the expression is 46.25
Answer:6.3×(15÷3+6.8)-28.09
Step-by-step explanation: Hello!
6.3×15÷3±6.8-28.09
You should probably use addition instead of subtraction so let's try:
First try the expression 6.3×15÷3+6.8-28.09
You have to make a set of parentheses. You should probably not include 6.3 in the parentheses so you can multiply whatever is in the parentheses by 6.3. You should also probably not include -28.09 in the parentheses because you will make a negative number in the parentheses that won't be able to be made positive. Try:
6.3×(15÷3+6.8)-28.09
6.3(5 + 6.8)-28.09
6.3(11.8)-28.09
74.34-28.09
=46.25
This is correct!
yuson must complete a certian number of hours of community service. she does 2 hours of service each day. after 8 days, yuson has completed half of her required community service. write a linear equation to represent the hours that yuson has left to do after x days.
Answer:
y = 32 -2x
Step-by-step explanation:
You want an equation for the remaining community service Yuson must complete after x days if she does 2 hours per day and is half done after 8 days.
RemainingYuson has completed (2 hr/day)·(8 day) = 16 hr of community service after 8 days. This is half the total required, so the initial amount required must be 2·16 = 32 hours.
After x days, 2x hours have been completed, reducing the amount remaining. Thus the amount remaining is ...
y = 32 -2x . . . . . hours left after x days

Answer:13
Step-by-step explanation:
(y-7)²=36
Us PENDAS (Please Excuse My Dear Aunt Sally)
Multiply the exponent by 7-7x-7=49
this leaves your equation as(y+49)=36
do the opposite from the equation to the value giveny=49-36
Sum it upy=13
Hope this helps! Good luck!
Answer:
Step-by-step explanation:
√(y - 7)^2 = √36
y - 7 = +-6
----------------
y - 7 = 6
y = 13
-----------------
y - 7 = -6
y = 1
---------------
Therefore, y = 13 or y = 1
------------------------------------
There is no answer for y = 1, so we choose y = 13.
2. The accuracy of a measured or estimated value compared to its actual value is described as the ____
options: markup, simple interest, percent change, markdown, principal
Answer:
I think percent change..?
Step-by-step explanation:
I don't know
12) Write as a percent: 0.538
13) Write as a percent: 3.2
14) Write as a percent: 0.74499
15) Write as a percent: 0.681
( thank you for the help! )
Answer: 12) 58.8%
13) 320%
14) 74.499%
15) 68.1%
Step-by-step explanation: To make a decimal a percentage, you need to multiply the decimal value by 100, like 0.499 as a percentage would be 49.9%, because I multiplied it by 100. Or, you could just move the decimal point 2 steps to the right.

Find equivalent ratios when the number of books ordered is 1, 2, and 3. Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid. (10 points)
Answer:
The equivalent ratios are: (1, 2), (2, 4), and (3, 6)
The graph can be plotted on a coordinate grid as shown in the diagram attached below.
Recall:
Ratio between two quantities, x and y, can be represented by the equation, y = kx, where k is the constant of proportionality.
k = y/x
Let x = number of books
y = cost (dollars)
Using any of the ordered pairs from the table, say, (7, 14), find k:
k = y/x = 14/7 = 2
Write the equation by plugging in the value of k into y = kx
y = 2x
Using the equation, y = 2x, find the equivalent ratios when x = 1, x = 2, and x = 3:
When x = 1:
y = 2(1) = 2 --> (1, 2)
When x = 2:
y = 2(2) = 4 ---> (2, 4)
When x = 3:
y = 2(3) = 6 ---> (3, 6)
The graph for the three equivalent ratios, (1, 2), (2, 4), and (3, 6) can be plotted on a coordinate grid as shown in the diagram attached below.

The table shows the largest known islands on Earth. What is the difference in the areas of Australia and Greenland? A. 2,442,330 sq. km B. 3,442,330 sq. km C. 3,442,330 sq. km D. 5,442,330 sq. km
Answer: The answer is 5,442,330.
Step-by-step explanation: Australia has an area of 7,617,930, and Greenland has an area of 2,175,600. 7,617,930 - 2,175,600 = 5,442,330.

Step-by-step explanation:Step-by-step explanation: Surface area of triangular prism = 2A + PH.
Lateral surface of a triangular prism = Length × (a + b + c)
i hope it helps u :-)
Answer:
Step-by-step explanation:
Area of triangle = bh/2
A = 4*5/2
A = 10 cm sq
A of 2 triangles = 10*2 = 20 cm sq
Now, Area of 1 rectangle = lb --> 10*5 = 50 cm sq
A of 3 rectangles = 50*3 = 150 cm sq
Now, LSA = 150 cm sq. (excluding the triangles)
TSA = A of tr. + A of rec. = 20 + 150 = 170 cm sq
Hope it helped. Pls mark me the BRAINLIEST! Don't fool pls

Find the diameter of a circle if the circumference is 8 cm. Round to the nearest tenth.
Answer: 2.55
Step-by-step explanation:
To find the diameter you divide the circumference by pi (3.14).
The formula is d=c/π
8/3.14 is 2.547... and when rounded would be 2.55 or 2.6 if rounded.

A group of students were asked which club they planned to join.
Club Percent of Students
Garden Club 0.1
Robotics Club 0.2
Technology Club 0.5
Zoology Club 0.2
Compare the probabilities of a randomly selected student joining a club and interpret the likelihood. Choose the statement that is true.
The student will be more likely to join the Robotics Club than the Garden Club because P(Robotics) > P(Garden).
The student will be equally likely to join the Robotics Club or Technology Club because P(Robotics) = P(Technology).
The student will be more unlikely to join the Zoology Club than the Robotics Club because P(Zoology) > P(Robotics).
The student will be more likely to join the Garden Club than the Robotics Club because P(Garden) < P(Robotics).
Answer: A - Robotics > Garden
Step-by-step explanation:
Hello! What you need to do is look at the decimals. You can write down which clubs have smaller decimals, equal decimals, and greater decimals than other clubs. You know that there is an equal probability for the Robotics Club and Zoology Club because 0.2 = 0.2
Robotics Club = Zoology Club
You also know that the Garden Club has the smallest percentage so:
Garden Club < Robotics Club = Zoology Club
And you also know that the technology club has the greatest percentage out of all of them so:
Garden Club < Robotics Club = Zoology Club < Technology Club
_<_ blank is less than blank, _>_ blank is more than blank, _=_ blank is equal to blank. A way I was able to remember this is that a smaller crocodile eats a bigger crocodile.
Now use the information you know:
Garden Club < Robotics Club = Zoology Club < Technology Club to figure out the answer.
Look at the last answer. You know the student is not more likely to join the Garden Club (0.1 or 10%) than the Robotics Club (0.2 or 20%) because the percentage of a student joining the garden club is smaller than the percentage of joining the Robotics Club. The formula shown for that answer is correct with Garden < Robotics, but what the rest of the answer says is incorrect.
Look at the third answer. You know that the student is not unlikely to join the Zoology Club (0.2 or 20%) than the Robotics Club (0.2 or 20%) because the probability of both is equal as shown in the formula previously made, Robotics Club = Zoology Club.
Look at the second answer. The percentage of a student joining the robotics club (0.2 or 20%) is smaller than the percentage of a student joining the technology club (0.5 or 50%), so they are not equally likely. The chance of a student joining the technology club is greater than the chance of a student joining the robotics club. This answer is also not correct.
Look at the first answer. The student is more likely to join the robotics club than the garden club because 0.2 (20%) is greater than 0.1 (10%). The formula is also correct because Robotics > Garden, or Robotics is greater than the probability of a student joining the garden club. The first answer is correct.
Given a circle with diameter of 12 inches, determine the following
The diameter is 12 inches.
radius=
Area =
(express your answer rounded to hundredths place)
Answer:
Radius = 6
Area= 113
Step-by-step explanation:
If you want to find the radius of a circle divide its diameter by 2.
If you want to find the diameter of a circle multiply its radius by 2.
To find an area of an circle do: Pi(Radius to the power of 2)
