Answer:

I would be interested to hear from others here, but first if you draw a venn diagram with two circles, label them A and B for candidates A and B, the intersection will be 25(i.e. number of voters that like both candidates. that means A\B will be 40 (only voted for A) and B/A will be 30 (only voted for B).  Of course, 40 + 30 + 25 only equals 95, and there were 100 voters, which means 5 did not vote for either candidate.  So that 5 will be outside set A and B. The "At Least" question normally implies the probability axiom P(not E) = 1 - P(E).

aksik [14]

Answer:

Marian can order 1,771 combinations

Step-by-step explanation:

In this question, we are interested in calculating the number of combinations Marian can order given that there are 23 flavors that can be served in three ways.

Mathematically, the number of combinations that can be ordered is simply 23C3

This is equal to 23!/(23-3)!3! = 23!/20!3! = 1,771

The number of combinations she can order is thus 1,771 combinations

Which ordered pair is the best approximation of the exact solution?
tino4ka555 [31]
For this case what you should do is observe the table that the values of y of both functions are as similar as possible.
 We observed that:
 For the x 1.6 coordinate we have:
  y = 1.2

y = 1.4
 Therefore, a good approximation of the solution is:
 \frac{(1.2 + 1.4)}{2} = 1.3 


 The ordered pair solution is:
 (1.6, 1.3)
 Answer:
 
(1.6, 1.3)option A

A concrete patio is 5 2/3 feet wide. And has an area of 36 5/6 square feet. Is the concrete slab long enough to fit a 7 foot pic
matrenka [14]

No.

We know the width is not long enough to lay the picnic table across, as it is only 5 2/3 ft. wide. We can see if the other side is long enough by dividing the product of the two sides by the side we know.

36 5/6 divided by 5 2/3 = 6 1/2 ft. which is not long enough to house a 7 ft. long picnic table without going diagonal.
