23 squared is 529 because 23 x 23 is 529, so the answer is D.
Answer:
A. 1)5.5 2)4.5 3)5.75 4)6.25 B. 1.75 C. A correct B incorrect C incorrect D correct
Step-by-step explanation:
Mean is a fancy way of saying <em><u>Average </u></em>, when calculating average you add all the numbers and divide by how many numbers there are:
<em><u>A</u></em>
<u>1.</u>
8+6+3+5=22/4=5.5
<u>2.</u>
5+7+4+2=18/4=4.5
<u>3.</u>
8+7+5+3=23/4=5.75
<u>4.</u>
6+8+4+5=25/4=6.25
<em><u>B</u></em>
largest mean is 6.25, smallest mean is 4.5:
<u>Subtract lowest mean from highest mean:</u>
6.25-4.5=1.75
<em><u>C</u></em>
<u>A)</u>
this is correct because averaging your average gives an overall average,
<u>B)</u>
if a is correct b has to be incorrect
<u>C)</u>
if D is correct C must be incorrect
<u>D)</u>
The closer they are together, that means more likely to be accurate because they are almost the same
I hope this helps u!
pls pls PLS give a brainliest and a thx ;)
Answer:
The answer would be B. With equations, what you do to one side you have to do to the other.
I solved it for you. hopefully this helps
Complementary angle add up to 90 degrees
UOI and UIO Triangles add to 180 and the IUO is 90 degrees so that leaves 90 degrees to the other 2 angles
AOU AND UOA Triangles add to 180 and the AUO is 90 degrees so that leaves 90 degrees to the other 2 angles
AIE AND EIA Triangles add to 180 and the IEA is 90 degrees so that leaves 90 degrees to the other 2 angles
supplementary angle add up to 180 degrees
Complementary pairs: UOI and UIO , AOU AND UOA ,AIE AND EIA
AUO and IUO Straight lines add to 180
AEI AND OIE 2 corners of the figure
EAO AND AOI 4 sided figures add to 360 and the other 2 corners are 90 each which is 180 so that leaves 180 for these 2 angles
Supplementary pairs: AUO and IUO ,AEI AND OIE, EAO AND AOI
