Answer:
<h2><em><u>0.84</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u> </u></em><em><u> </u></em>
Total no. of observation = 50
Given, No. of observations that told yes = 42
<em><u>Therefore</u></em><em><u>, </u></em>
Probability of getting response as yes
In decimal form ,
= <em><u>0.84 (Ans)</u></em>
d = dimes
q = quarters
d+q = 38 coins
q=38-d
0.25q + 0.10d=6.95
0.25(38-d)+0.10d=6.95
9.5-0.25d+0.10d=6.95
-015d=-2.55
d=-2.55/-0.15 = 17
q=38-17 =21
21*0.25 =5.25
17*0.10 = 1.70
5.25+1.70 = 6.95
she had 21 quarters and 17 dimes
Answer:
4(3x+y)^2
Step-by-step explanation:
36x^2+24xy+4y^2
=9*4x^2+6*4xy+4y^2
=4(9x^2+6xy+y^2)
=4(3x+y)*(3x+y)
=4(3x+y)^2
