Answer:
280 said YES
120 said NO
56 drink at least 3 cups
224 do not drink at least 3 cups
56/400 drink 3 cups a day or 7/50 simplified.
Step-by-step explanation:
To complete the frequency table use the sample size 400, 7/10 say yes, and 20% drink at least 3 cups.
- If 7/10 people say yes, then 3/10 people say no. 7/10 as a decimal is 0.7. Multiply 0.7 by the sample size 400 to find the amount of people.
0.7(400) = 280
This means 280 people say yes. And 120 must say no.
- If 20% drink at least 3 cups then 0.20 is the decimal conversion. To find the amount multiply 0.20 by the same size 280 (the amount who said yes).
0.2(280) = 56
This means 56 people said YES and drink at least 3 cups. And 224 who said YES do not.
This also means 56 out of the whole sample size of 400 drink 3 cups. THe fraction is 56/400 or 7/50 simplified.
Answer:
-3
Step-by-step explanation:
ax + by + c = 0
Slope = -a/b
So, 3x + y = 15
Slope = -3/1 = -3
Pressure<span> is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. We calculate the pressure applied to the system above by the expression:
P = F / A
where F = mg
P = mg / A
P = (7.5 x 9.8) / 0.6
P = 122.5 Pa</span>
B because absolute value means the distance of a point on a number line from 0. So the absolute value of -6 is 6 and you add that to 4
Answer: I imagine that the question was: "What is the wrong answer between these choices?" Therefore, it is the third choice.
Explanation:
2(m∠PQS) ≠ (m∠RQS)
2(47°) ≠ 47°
94° ≠ 47°
