Hope this helps.
Answer:
Step-by-step explanation:
given that the pair of parametric equations represents a line, parabola, circle, ellipse, or hyperbola.
We are given
We know in hyperbolic functions
Using this we can find out
Using the identity we can say that
this is nothing but a hyperbola.
a =3 and b =4

Answer: 132 children's tickets and 251 adult tickets were sold.
Step-by-step explanation:
Let x represent the number of children tickets that were sold.
Let y represent the number of adult tickets that were sold.
A total number of 383 tickets were sold. This means that
x + y = 383
Children's tickets cost $4 each and adult tickets cost $6 each. If the total amount for which the tickets were sold is $2034, it means that
4x + 6y = 2034 - - - - - - - - -- -1
Substituting x = 383 - y into equation 1, it becomes
4(383 - y) + 6y = 2034
1532 - 4y + 6y = 2034
- 4y + 6y = 2034 - 1532
2y = 502
y = 502/2
y = 251
x = 383 - y = 383 - 251
x = 132
Answer:
c. 0.088
Step-by-step explanation:
Let p(s) be the proportion of apples defected in the sample. The probability that p(s)<0.05 can be calculated by calculating z statistic of 0.05:
where
- p is the proportion of the apples in fact defected (0.08)
- N is the sample size (150) Then,
z(0.05)=
And P(z<-1.354)≈0.0879
Therefore the probability that a random sample of 150 among 8% defected apples can be accepted is 0.088.
