Answer: D the final mean is higher than the original
Step-by-step explanation:
90+85+98+60+84+78/6= 82.5 as the original mean
dropping 60 which is the lowest grade means 90+85+98+84+78/5=87 which means the new mean is 87 which is greater than the original mean of 82.5
So the answer is D

A student worked out the following problem: Solve: 8x + 10 – 6x + 4 = 24 Step 1: 2x + 14 = 24 Step 2: 2x = 38 Step 3: x = 19
A) There is an error in step 1
B) There is an error in step 2
C) There is an error in step 3
D) There is no error
Answer
b
Step-by-step explanation:
Answer:
B) There is an error in step 2.
Step-by-step explanation:
When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).
After combing your like terms, you now have the equation 2x+14=24.
You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10
This is where the student made the mistake. Instead of subtracting 14, they added 14.
The final step would be to divide by 2 on both sides.
At the end of the problem, you are left with x=5.

After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air (from the time it leave's Dan's hand to the time it enters the basket),
Josephine says she can do this by using Dan's equation (1) = -1649 +18 + 8) and setting the equation equal to zero. Dan doesn't think Josephine's thinking is correct.
Who do you agree with?
Explain your reasoning using mathematical evidence.
Answer:
Step-by-step explanation:
The function is to blurry to see but you would not set the height function equal to zero. Instead h should be set to the height of the basket. The time elapsed would be the second time the ball was at the height of the basket. If I guess what the function is as
-16t^2+18t+8=10
-16t^2+18t-2=0
-16t^2+16t+2t-2=0
-16t(t-1)+2(t-1)=0
(-16t+2)(t-1)=0
So the ball is at 10ft at 0.125s and 1s. So it enters the hoop after 1 second. Of course this is dependent on if I guessed at the correct equation from the picture.

3(1 - 2a) = -3a - 18
Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7

While selling 15 copies, a man gains the cost price of 5 copies, find the profit percent.
Answer:
If the price is p and the cost is c, then

Find the slope of the line that passes through the pair of points (6,-2) and (5,-4).
Show all work necessary and write your final answer in the box.
Answer:
slope = -10/7Step-by-step explanation:
co-ordinates = (6,-2) (5,-4)
slope = (y² - y¹) / (x² - x¹)
slope = (-4 - 6) / (5 - (-2))
slope = (-10) / (5+2)
slope = (-10) / 7
slope = -10 / 7
Answer:
10/7

How do I find the center and angle of rotation
9514 1404 393
Answer:
B → XC → YD → Z180° rotation about the originStep-by-step explanation:
In general, if PQ is rotated to P'Q', the center of rotation (O) will be the point of intersection of the perpendicular bisectors of PP' and QQ'. The angle of rotation will be the angle POP', or QOQ'.
__
The correspondence between preimage vertices ABCD and image vertices can be found by naming the vertices in the same order (clockwise) from one whose correspondence you know.
Here, the correspondence between A and W is given. Vertices clockwise from W are WXYZ, so those are the image points corresponding to ABCD.
__
We note that the midpoints of AW and BX are coincident at the origin. That is, the perpendicular bisectors of these segments are coincident at the origin, so the origin (point O) is the center of rotation. The rotation angle is AOW, an angle that measures 180°.
__
The image point coordinates are the opposites of the preimage point coordinates.
A(2, 2) ⇒ W(-2, -2)
B(2, 5) ⇒ X(-2, -5)
C(5, 5) ⇒ Y(-5, -5)
D(5, 2) ⇒ Z(-5, -2)
This is another indication that the rotation is 180° about the origin, since that rotation results in the mapping ...
(x, y) ⇒ (-x, -y) . . . . . rotation 180° about the origin
Yall plzz helpp I dont want to fail math "what is the longest walking stick that can be placed in the bottom of a truck of length 80 cm and width 60cm"
Given:
Length of the truck = 80 cm
Width of the truck = 60 cm
To find:
The longest walking stick that can be placed in the bottom of a truck.
Solution:
The longest walking stick that can be placed in the bottom of a truck is the diagonal of the truck.
We know that, the diagonal of a rectangle is:
[tex]d=\sqrt{l^2+w^2}[/tex]
Where, l is the length and w is the width.
Putting [tex]l=80[/tex] and [tex]w=60[/tex], we get
[tex]d=\sqrt{(80)^2+(60)^2}[/tex]
[tex]d=\sqrt{6400+3600}[/tex]
[tex]d=\sqrt{10000}[/tex]
[tex]d=100[/tex]
Therefore, the length of the longest walking stick that can be placed in the bottom of a truck is 100 cm.
The approximate areas of two states are listed below.
Texas: 2.69×10^5 square miles
Rhode Island: 1.21×10^3 square miles
Determine the difference, in square miles, between the area of Texas and the area of Rhode Island. Write your answer in scientific notation.
Answer: _________________ square miles
Answer:
2.6779*10^5
Step-by-step explanation:
2.69 * 10^5 - 1.21 * 10^3
This is 2.6779*10^5 :)
The difference between the areas of Texas and the area of Rhode Island is given by equation A = 2.6779 x 10⁵ miles²
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the area of Texas be p = 2.69 x 10⁵ miles²
Let the area of Rhode Island be q = 1.21 x 10³ miles
Now , the difference of areas A = p - q
On simplifying the equation , we get
The difference between the area of Texas and the area of Rhode Island A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles
A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles
A = 10³ ( 2.69 x 100 - 1.21 )
On further simplification , we get
A = 10³ ( 269 - 1.21 )
A = 267.79 x 10³
A = 2.6779 x 10⁵ miles²
Hence , the difference in areas is 2.6779 x 10⁵ miles²

Answer:
i love ur art its amazeballs and an asteroid thing
Step-by-step explanation:
On one island there lived two friends, Ana and Banana. One of them always tells the truth, while the other always lies. When asked which one is the liar among them, they said: Ana: "Banana ate ten apples yesterday, and he is telling the truth." Banana: "No, I ate five apples yesterday, and Ana is lying." How many apples did Banana eat yesterday?
Answer:
Number of apples ate = 5
Step-by-step explanation:
Fact:
One of them always tells the truth, while the other always lies.
To find how many apples banana ate, we have to figure out who is lying between Ana and Banana.
Ana: "Banana ate ten apples yesterday, and he is telling the truth."
If Ana is telling the truth, that means Banana is also telling the truth because of the statement (... and he is telling the truth).
This is not possible as one of them must be lying. The only option left is that Ana is lying.
Since Ana is lying, it means banana is telling the truth.
Banana: "No, I ate five apples yesterday, and Ana is lying."
Number of apples ate = 5
