Answer:
k = 4
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
. So
P(X < k) = 0.6625
k only assumes discrete values, so
We have to find the cummulative distribution until we hit 0.6625. So
So k = 4

The rate of change of the linear function whose graph passes through points (-5, -2) and (-2, 6) is: 2.7.
<h3>What is the Rate of Change of a Linear Function?</h3>
The rate of change of a linear function is given as change in y over change in x.
Given the points:
(-5, -2) and (-2, 6)
Change in y = 6 -(-2) = 8 units
Change in x = -2 -(-5) = 3 units
Rate of change = 8/3 = 2.7.

Answer:
10. 4/23
11. 18/23
12. 19/23
Step-by-step explanation:
In order to find any of these, first note the total amount of fruit. When you add all the types together you get 115 pieces of fruit. Now for each probability, divide the number of fruit that fit the description by the amount total.
20 apples/ 115 total = 4/23
90 non-pears/ 115 total = 18/23
95 non-apples/ 115 tota = 19/23
The function that represents a geometric sequence is given by:
C. , where n is a positive integer.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
In which is the first term.
Following this pattern, a function that is also a geometric sequence is:
C. , where n is a positive integer.
For the function, we have that:
.
