Answer:
5/78 chance to get a Nickel and then a penny without replacing
Step-by-step explanation:
The bag contains a total of 40 coins which show that the probability of getting a Nickel is 5/40 and the probability of getting a penny after taking out a nickel is 20/39. In order to find the Probability of two events together you must multiply the probabilities so
(5/40) * (20/39) = 100/1560 = 5/78
Answer:
It's C, g(x) = (1/2)^x
This is a horizontal reflection of y = 2^x
across the y axis.
Step-by-step explanation:
Using the process of elimination, you can spot this answer by applying what is logical about the transformations of an exponential function.
The transformations of a standard exponential function can be given by:
ab^(1/c(x-h))+k
First note that A must be incorrect because -2^x would be a reflection across the x axis which would not match the function g because a reflection across the x axis would cause the exponential growth or decay value b to become a reciprocal and -2 is not a reciprocal of 2.
Answer:
C. x = -1 1/2
Step-by-step explanation:
16x - 5 = 18x - 2
-16x. -16x
-5 = 2x - 2
+2. +2
-3 = 2x
/2. /2
-3/2 = x
-1 1/2 = x
It's a prime number meaning only 1 and 67 are the only whole numbers that will give you 67
