Grace made a dot plot showing the distances she ran each day for two weeks.
She says that she usually runs 7 miles each day because that is the distance that occurs most often.
Do you agree with Grace’s reasoning?
Use the drop-down menus to explain and show your answer.
Dot plot named as ALTDCDistances RunALTDC has number line from 1 to 7. 1 dot on 1, 3 dots on 2, 3 dots on 3, 3 dots on 4 and 4 dots on 7 are given.
The mode, which is (3,4, or 7) ,(is or is not) a typical distance for the data. The median, which is (3.5,4, or 7),(is or is not) a typical distance for the data. The mean, which is (3,4, or 7) ,(is or is not) a typical distance for the data. So, Grace’s reasoning(is or is not ) correct.

Write an equation to represent the amount of water in the bucket, y, in terms of the number of minutes, x, since the faucet was turned on
Answer:
y= 3x+125
Step-by-step explanation:
y intercept is 125
gradient is 3
y=Mx+c
y=3x+125
Answer:
y = 75x + 125
Step-by-step explanation:
Write in form y = mx + b
75 is the slope (m)
125 is the y-intercept (b)
So the equation would be y = 75x + 125.
BTW, the slope is written in rise/run form. For this graph, it is 75/1.
Hope this helps!

Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2
Step-by-step explanation:
We have to simplify the given expression:
1. 3x+2y-2x+23x+2y−2x+2
Combining the like terms,we get the second step as
2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)
Now, taking 'x' common from the first two terms, we get third step as:
3. (3-2)x+2y+2(3−2)x+2y+2
Now, simplifying the expressions among the like terms, we get fourth step as:
4. x+2y+2x+2y+2

of the trains?
b. What does the solution tell about the locations of the trains if they
left the station at the same time? If they left at different times?

Edith bought a science book and a math book for her college classes. The cost s, in dollars, of the science book is $28.75 more than the cost m, in dollars, of the math book. Write an equation that relates the prices of the two books.
Answer:
do m= 28.75 minus S
or do s= 28.75 minus m
Step-by-step explanation:
do m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus m
alice average mark for 4 science exams is 68%. Can alice score enough marks In a fifth exam so that her average Mark increases to 75% give reasons
Answer:
it is impossible she gets a 75% because as far as we know she can only score a maximum of 100 and she needs a 103
Step-by-step explanation:
We're going to assume that alice got a 68 on all 4 of her science exams
which means that so far we have[tex]\frac{68+68+68+68}{4}=68[/tex]
And we need to find out if she can get a 75 which means that we have the following
[tex]\frac{68+68+68+68+x}{5}=75[/tex]
Solve for x
272+x=375
x= 103
Therefore (unless there is extra credit available in the exam) it is impossible she gets a 75% because as far as we know she can only score a maximum of 100
Write the equation for the model below. Then solve for x.

is this statement valid or invalid "if an animal has feathers, than it is a bird. a crow has feathers, so it is a bird"
Answer:
the statement is valid!
Step-by-step explanation:
first, let's consider the first statement "if an animal has feathers, then it is a bird"
well, let's think about this: are there any animals that have feathers that AREN'T birds? No!
so we know the first statement is true so it is valid
now, let's consider the second statement "a crow has feathers, so it is a bird"
is that true? well based on the first statement, if an animal has feathers it's a bird. so yes! the statement is valid
Answer: The statement is valid.
======================================================
Explanation:
This is valid by the law of detachment. This is also known as "modus ponens".
The basic format is that we have these two premises
If P is true, then Q is trueP is trueThose two premises work together to conclude that Q must be true. Think of it like a set of dominoes. The first domino that you knock over is statement P, which then leads to domino Q being knocked over afterward (ie statement Q must be true because P is true).

Your first bungee jump is 50 1/6 feet higher than your second jump. Your first jump reaches −200 2/5 feet. Select the equation you can use to find the height h (in feet) of your second jump. Then find the height of your second jump.
Answer:
h= −250 17/30
Step-by-step explanation:
Let's solve your equation step-by-step.
−200 2/5 −50 1/6 = h
Step 1: Simplify both sides of the equation.
−7517/30 = h
Step 2: Flip the equation.
h = −7517/30
