Shaan’s math homework scores for the semester are 90, 85, 98, 60, 84, and 78. Shaan’s teacher said she would drop the lowest homework score when calculating grades. How does the mean of Shaan’s actual math scores compare to the mean of the scores when the lowest one is dropped?
a. The relationship cannot be determined.
b. The final mean is the same as the original.
c. The final mean is lower than the original.
d. The final mean is higher than the original.
Answers
Answer:
The final mean is higher
Step-by-step explanation:
The mean of all the scores = [tex]\frac{90 + 85 + 98 + 60 + 84 + 78}{6\\} = \frac{495}{6} = 82.5\\[/tex]
The mean of the scores with the 60 dropped = [tex]\frac{435}{5} = 87[/tex]
The final mean is higher
That will always happen when you drop the lowest score. I worked it out for you so that you would see that it happened in your case.

The figure below is reflected over y-axis and then rotated 180° counterclockwise.
What are the coordinates of the image of point Y after these transformations?
Answers
Answer:
The coordinates of point y after the transformation is (-6,5)
Step-by-step explanation:
Firstly , we need to get the coordinates of the point y before the transformation
The coordinates are
(-6,-5)
By reflecting over the y-axis, we have the following change;
(x,y) becomes (-x,y)
So we have;
(6,-5)
Then we are to rotate at an angle of 180 degrees counterclockwise
The operation here will be;
(x,y) to (-x,-y)
So we have;
(6,-5) to (-6,5)

Find the length of side a.
Answers
Answer:
C. 5
Step-by-step explanation:
Keeping in mind that this is a right triangle, to find the length of side a, we can use the Pythagorean Theorem.
Remember, the Pythagorean Theorem is:
a² + b² = c²
where a and b are the legs of the right triangle and c is the hypotenuse.
As we can see in the image, a is one of the two legs of the right triangle. 13 is the hypotenuse and 12 is another leg. Plugging into the Pythagorean Theorem, we get:
a² + 12² = 13²
Now we solve for a.
a² + 144 = 169
Subtract 144 from both sides.
a² = 169 - 144
a² = 25
Take the square root of both sides.
a = √25
a = 5
So the length of side a would be 5.
The answer would be C. 5.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer: C. 5
Step-by-step explanation:
We'll use the Pythagorean Theorem to find the missing side.
a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
(simplify)
[tex]a^2 = \sqrt{25}[/tex]
a = 5

Factor 60y-90-20x to identify the equivalent expressions. Choose two answers.
5(14-16-4x)
2(30-45-10)
5(12y-18-4x)
10(6y-9-2x)
Answers
Step-by-step explanation:
One evident common factor between 60, 90, & 20 is 10 because all these numbers end in a 0; Therefore one way to factor the equation 60y - 90 - 20x is;
10 (6y – 9 – 2x)
5 is also a common factor between the numbers 60, 90, & 20
60/5 = 12; 90/5 = 18; 20/5 = 4
Therefore 60y - 90 - 20x is also equal to;
5 (12y – 18 – 4x)

Step-by-step explanation:
The distributive property tells you the outside factor multiplies each term inside parentheses.
a(b +c) = ab +ac
(-3/8)(4/7 +(-11/7)) = (-3/8)(4/7) + (-3/8)(-11/7)

A farmer needs to plant 180 tomato plants. He can plant 9 plants every 15 minutes.
a) What percentage of the planting will be complete after 75 minutes?
It will be
% complete.
b) How many minutes will it take to finish 90% of the planting?
It will take ____ minutes.
Answers
Answer:
52.94%
270 minutes
Step-by-step explanation:
1. 9 plants - 15 minutes
x plants - 75 minutes
Cross multiply
15x = 75 x 9
15x = 675
Divide both sides by 15
x = 675/15
x = 45 plants
45/85 x 100
= 52.94%
2. 90% of 180
= 90/100 x 180
= 162 plants
9 plants - 15 minutes
162 plants - x minutes
Cross multiply
9x = 162 x 15
9x = 2430
Divide both sides by 9
x = 2430/9
x = 270 minutes or 4 hours 30 minutes.
