First, you can see that female business is 44-30=14. Then, you can see that female premium is 62+14+x=108, or x=32. So, because 32 females bought premium and there are 60 total premium, the number of male premium is 60-32=28 male premium tickets.

A polling company plans to create a probability model for a state election. In a telephone survey of 750 residents who stated they were registered to vote, they found that 318 planned to vote for the Democratic candidate, 268 planned to vote for the Republican candidate, with the remainder were undecided. What is a reasonable probability model for the state election?
Select the correct ANSWERS from the list below
54% plan to vote for the Democratic candidate|
22% are undecided.
18% are undecided.
36% plan to vote for the Republican candidate.
46% plan to vote for the Republican candidate.
42% plan to vote for the Democratic candidate
this decides my grade please only answer if you know it
Answers
Answer:
22% are undecided
36% plan to vote Republican
42% plan to vote Democratic
Step-by-step explanation:
Take 318 and divide it by 750 to find the democratic vote. Round to the nearest whole number.
318/750 = 0.424
Same for Republican except take 268 and divide by 750.
268/750 = 0.357
Add both percentages together. 36% + 42% = 78%
So there is 22% of the population that either did not answer or are undecided.
The correct answers are:
22% are undecided
36% plan to vote Republican
42% plan to vote Democratic
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Total Resident = 750
Out of which 318 planned to vote for the Democratic candidate, 268 planned to vote for the Republican candidate.
So, 318/750 = 0.424
= 42.4%
and, 268/750 = 0.357
= 35.7%
So, the percentage who decided to vote = 36% + 42% = 78%
Hence, there is 22% of the population that either did not answer or are undecided.

Stacia has 28 red and blue marbles. The ratio of red to blue marbles is 1:6. How many blue marbles does Stacia have?
Answers
Answer:
The total number of blue marbles = 24Step-by-step explanation:
Total number marbles Stacia has = 28
The ratio of red to blue marbles = 1 : 6
Let 'r' be the number of red marbles.Let 'b' be the number of blue linesAs the total number of marbles is 28. Thus,
r + b = 28
As the ratio of red to blue marbles is 1 to 6.
It means for each red marble 'r', we have 6 blue 'b' marbles. Thus,
b = 6r
now substituting b = 6r in the equation r + b = 28
r + b = 28
r + 6r = 28
7r = 28
divide both sides by 7
7r/7 = 28/7
r = 4
Thus,
The total number of red marbles ⇒ r = 4
The total number of blue marbles ⇒ b = 6r = 6(4) = 24
Therefore,
The total number of blue marbles = 24Write the equation of the directrix of the parabola shown below.

suppose: tan x = t
(1)=> t² + t - 12 = 0
a = 1 b = 1 c = -12
⇒ Δ = b² - 4ac = 1 + 48 = 49 > 0 => has 2 solutions
=> t = [tex]\frac{1+\sqrt{49} }{2}=\frac{8}{2}=4[/tex]
or t = [tex]\frac{1-\sqrt{49} }{2}=\frac{-6}{2}= -3[/tex]
because t = tan x => tan x = 4 or tan x = -3
because x ∈ [0;2pi) => with tan x = 4 => x = arctan(4) or x = arctan(4) + pi
with tan x = -3 => x = arctan(-3) + pi
