Answer:
7
Step-by-step explanation:
1/7+1/3= 3/21+7/21= 10/21= 0.476190
the 6 digits after the decimal point get repeated
6*3= 18- three full cycles and the second digit after 3 cycles = 7 so the 20th digit is 7
Written out, this would be (x / 7) - 10 < -6
solved, it would be x < 28
i’m pretty sure the answer is 3
21 divided by 7 equals 3
4x = 32 - 2x
Add -2x (or subtract 2x) from each side
2x = 32
Divide both sides by 2
x = 16
The second survey is more believable because there is randomness in the second rather than the first survey. Since the second company surveyed in all interest levels while the first company only surveyed their best customers. Random sampling like what the second company did helps produce representative samples by removing voluntary response bias and undercover age bias.
