Answer:
Mean: 3.5263157894737
Median: 3
Mode: 3
Step-by-step explanation: The mode is 3 because the mode is for which number pops up the most, which is 3.
I got the median by crossing out 8 from the left and the right of the number set and got 3 as the last number.
I got the mean by adding up all the numbers and divided it by the amount of numbers in the set.
Answer:
D. 4
Step-by-step explanation:
x is greater than 3, which means x has to be a higher number. the only option here that is higher than 3 is 4.
Answer:
60%
Step-by-step explanation:
Write 0.6 as 0.60, which is 60 hundredths. 60 hundredths is 60 percent. You can also move the decimal point two places to the right to find the percent equivalent.
a and b are correct
c is wrong
d can't be decided, because it can be true for one case, but not for others.
so only go for a and b
Answer: A. The two triangles are not similar because x≠20 and there cannot be three congruent interior angels.
Step-by-step explanation:
Given: △ABC has interior angles with measures x°, 90°, and 65°
△DEF has interior angles with measures y°, 65°, and 20°.
If △ABC is similar to △DEF then their corresponding angles should be equal.
Suppose △ABC is similar to △DEF then x=20°
But in △ABC
x+90°+65°=180° [angle sum property of triangle]
⇒x+155°=180°
⇒x=180°-155°
⇒x=25°
⇒x≠20°
⇒△ABC is not similar to △DEF.
Therefore A is the right option.
