Answer:
B) They estimate that 2.3% of those surveyed answered incorrectly
Step-by-step explanation:
hope it helps you dude
(A)
To change a percentage to a decimal, move the decimal point to the left two place values, and drop the percent sign.
35% = 0.35
(B)
To change 0.35 to a fraction, move the decimal point back to the right 2 place values, and set the number over 100
0.35 = 35/100
Simplify. Divide 5 from both the numerator and denominator
(35/100)/(5/5) = 7/20
7/20 is your answer
To write 35% as reduced fraction:
Find the GCD (or HCF) of numerator and denominator
GCD of 7 and 20 is 1
Divide both the numerator and denominator by the GCD
7 ÷ 1
20 ÷ 1
Reduced fraction:
7/20
Therefore, 7/20 simplified is 7/20

Answer:
30% of picking a red marble, it is likely to occur.
Step-by-step explanation:
50% of green and 20% of blue. The most logical is to add to 100%. 50+20=70, 100-70=30. Thats the 30% of red. Since red is 10% than blue, it is likely to get a red marble.
Answer:
72yd2
Step-by-step explanation:
making figure into 2
1st figure
= 6×5
= 30yd^2
2nd figure
= 14×3
= 42yd^2
Area of the full figure
= (30+42)yd^2
= 72yd^2
