Answer:
231
Step-by-step explanation:
35 % = 0.35
35 % of the students participate in sports
No. of students participating = 0.35 × 660 = 231
Answer:
area = 240 in²
Step-by-step explanation:
each triangle area = 1/2(4)(15) =30 in²
30 x 8 = 240 in²
Answer:
0.2839 = 28.93%
Step-by-step explanation:
In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z
Le x be tons of coal in a car
Z = (x – mean)/standard deviation
Z = (x – μ)/ σ
P (x<68.5) = P(z < (68.5-69)/0.9)
P (x<68.5) = P(z < -0.5555)
Then we use the z table to find the area under the curve.
P (x<68.5) = 0.2893
The choices are:
A)
2x - 15 ≤ 4y
B)
2x - 15 ≥ 4y
C)
15 - 2x ≤ 4y
D)
<span>15 - 2x ≥ 4y
</span>
Therefore, the best and most correct answer among the choices provided by the question is the fourth choice "<span>15 - 2x ≥ 4y". </span>I hope my answer has come to your help. God bless and have a nice day ahead!
i’m pretty positive you would just subtract!
