Car 2 will drive faster im not sure but thats my answer
A24 = 141,
using equation,
an = a1 + (n-1)d,
a8 = a + 7d = 45
a16 = a + 15d = 93
solve simultaneously for values a and d, where a = 3, and d = 6.
therefore, inserting values into a24 eqn, where
a24 = 3 + (24-1)(6) = 141.
C - remember the vertical line test determines if something is a function. A function has 1 x value for 1 y value. A B and D have more than one y value for a given x value.

Let x be the number of adults (under 50 years old) after a 12-hour fast where X ~ N(85,25)
The problem is missing some parts but here are the answers:
(a) x is more than 60
z(60) = (60-85)/25 = -1
P(x > 60) = P(z > -1) = 0.158655
(b) x is less than 110
z(110) = (110-85)/25 = 1
P(x < 110) = P(z < 1) = 0.841345
