The correct answer is that "Dish A has a greater rate of change."
In Dish A, the values are going up by 2 each day. In Dish B, the values are staying the same.
Therefore, Dish A has a greater rate of change.
Answer:
Option C
Step-by-step explanation:
If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.
Let's try this with option C. To make things easier, convert -4.5 into decimal form:
. Substitute
for x and 10 for y in the equation, then solve:

10 does equal 10, so this is a true statement. Option C is the right answer.
Answer:
= 9.2 cm
Step-by-step explanation:
D = C ÷ π
= 29cm ÷ 3.14
= 9.2356
= 9.2 cm
Answer:
a) p=0.2
b) probability of passing is 0.01696
.
c) The expected value of correct questions is 1.2
Step-by-step explanation:
a) Since each question has 5 options, all of them equally likely, and only one correct answer, then the probability of having a correct answer is 1/5 = 0.2.
b) Let X be the number of correct answers. We will model this situation by considering X as a binomial random variable with a success probability of p=0.2 and having n=6 samples. We have the following for k=0,1,2,3,4,5,6
.
Recall that
In this case, the student passes if X is at least four correct questions, then

c)The expected value of a binomial random variable with parameters n and p is
. IN our case, n=6 and p =0.2. Then the expected value of correct answers is
