Answer:
first blank negitave
second blank positive
Step-by-step explanation:
Solution :
Let x be student will be left handed
P = 0.09
Using the normal approximation to binomial distribution,
a). n = 108,
μ = np = 9.72
= 2.9741
Required probability,
P(x=8) = P(7.5 < x < 8.5)
Using z table,
= P(z<-0.41)-P(z<-0.75)
= 0.3409-0.2266
= 0.1143
b). P(x=12) = P(11.5 < x < 12.5)
Using z table,
= P(z< 0.94)-P(z< 0.60)
= 0.8294 - 0.7257
= 0.1006
Answer: 15 inches
Step-by-step explanation:
Volume(V) = 40 cubic inches
Height (h) = 8 inches
1.) Volume of cone = (1/3) × base(B) × h
2.) 40 = (1/3) × base × 8
3.) 40 = (8/3) × base
4.) Multiply both sides by the reciprocal (3/8)
(40) × (3/8) = (8/3) × (3/8) × base
120/8 = base
15 = base
Therefore, base area of cone = 15 inches
I am assuming that the question is asking for the equation of the line if it goes through those coordinates. In which case, the answer would be A. y = x - 4
We can see this because if we substitute in any of the x and y values, the equation is correct:
5 = 9 - 4
0 = 4 - 4
1 = 5 - 4
I hope this helps!
