Answer:

Mean would be most affected

Step-by-step explanation:

The mean is defined as the average value . If the data has extreme values then the average value automatically changes.

The median is the value which divides the data in to two halves. It is not affected by the extreme values. The middle value remains the same.

The mode is the value which occurs repeatedly. An extreme value in a data does not affect the mode.

For example I have 5 chocolate bars of sizes 5,6,7,7,9 and another 5 chocolate bars of sizes 5,6,7,7,12

Mean for the two sizes will be 34/5= 6.8 and 37/5=7.4

The median and mode in both sets is 7

So the mean is most affected with change in value.

Which of the following is a perfect square trinomial?

shutvik [7]

Answer:

Step-by-step explanation:

Take a look at what happens when squaring either of these...

$(ax-by)^2=(ax-by)(ax-by)=a^2x^2-2abxy+b^2y^2\\\\(ax+by)^2=(ax+by)(ax+by)=a^2x^2+2abxy+b^2y^2\\$

Notice a couple of patterns.

1. The last term has a positive coefficient. That rules out answer choices C and D.

2. The coefficient of the middle term is either $+2ab \text{ or } -2ab$ . So what are a and b? a is the square root of the x^2 term and b is the square root of the y^2 term.

$25x^2 \Rightarrow a=5\\\\9y^2 \Rightarrow b=3\\\\ab=15\\\\2ab=30$

The middle coefficient needs to be either +30 or -30. The answer is choice A.

Angle A and angle B are supplementary angles. If m angle A = (5x+2) and m angle B = (8x+9) , then find the measure of angle B

otez555 [7]

You first identify what supplementary angles are,angles that add up to 180.
5x+2+8x+9=180
17x+11=180-11
17x=169
x=169divided by 17
x=9.9411
x=10 when rounded into the next value
8x*10=80+989
