The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the total number of observations by the total number of observations.
Given:
Mac has taken seven math exams this year.
His average mark is 78%.
Let x be the required score.
To find the mark to raise his average to 80%:
According to the question,
78(7) + x = 8(80)
546 + x = 640
x = 640 - 546
x = 90
Therefore, the required mark is 90.

. Bryon competes on the school debate team. He won 0.40 of the debates in which he participated. Which statement is not true about Byron's debates?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Since Bryon won 0.40 of his debate, this means that he won 40% of his debate. 40% converted to fraction equals 40/100 = 2/5.
Since he won 40%, it means that he lost (100% - 40%) = 60%. He lost 3/5 and won 2/5.

What is the name of the transformation in which each point on a figure is turned through a given angle and direction around a given point?
Answer:
rotationStep-by-step explanation:
A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.
Therefore, the fixed point is called the center of rotation.
What are the angles?
Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'.
A rotation means that the transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point.
So,the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.
Hence, the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

PLEASE HELP ASAP ILL GIVE YOU 30 POINTS Jamie is excited for spring break this year. Her family is planning a vacation! She fully intends to take 20 pictures each day. checking her phone before leaving she notices she has 75 pictures already on the phone.
Given that the vacation will last a full seven days and Jamie's phone can hold a total of 200 pictures. How many pictures will she need to delete an order to make enough room in her phone for vacation photos?
Answer:
15 photos
Step-by-step explanation:
one can start off by first seeing how many photos will be taken on the vacation. We can do that by multiplying the days with how many photos will be taken for each- so 20×7= 140. Then we can take the total amount of photos the phone cam hold-200 subtract what we already have 200-75= 125 thats how much space if left but we need more (140). So the. we can start making quick guesses by taking 5 from 75 and see what we get then taking another 5 and another if needed we get 60 that finally gives when subtracted from 200- 200-60=140 the amount of space we need. Then finally we can just do 75-60 to get the total amount of photos we must delete. 75-60= 15
At a sale this week, a desk is being sold for $133 . This is 35% of the original price.
What is the original price?
Answer:
392.35
Step-by-step explanation:
35% + 35% is 70 % so 133 +133 is 70 % witch is 269.
next we need to figure out 30 percent and they give us 35 % so. you add to zeros to 30 because percentage is out of 100 and there are 2 zeros in 100. so it look like this
3000 ÷ 133 = 22.56 is 30% of 133
70% + 30% = 100%
269 + 22.56= 291.56 is your answer
