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.

Answers
Answer:
The population is: all glass recycled
The sample is: the 10 selected glass items.
The parameter is the proportion of: all his glass that is clear
The statistic is the proportion of: the selected glass that is clear
The population of a distribution is the entire group, while the sample is the selected group from the entire group.
The population is all glass recycled The sample is the 10 selected glass items. The parameter is the proportion of all his glass that is clear The statistic is the proportion of the selected glass that is clearThe population
From the question, we understand that glasses are recycled and then separated into colors.
This means that, the population is all glass recycled
The sample
From the question, we understand that he randomly grabs 10 glass items, and then determine the proportion of clear glasses.
This means that, the sample is the 10 selected glass items.
The parameter
This is the value that summarizes all the glasses that are being recycled.
So, the parameter is the proportion of all his clear glasses
The statistic
This is the value that summarizes the selected glasses.
So, the statistic is the proportion of the selected glass that is clear

Answer:
tan²x + tan x - 12 = 0 (1)
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

If QRS = MNP, QR = 11, QS = 15, MP = 2x + 1, S = 84, R = 32, and M = (17y - 4),
find the values of x and y.
pls answer quick
Answers
Answer:
x = 7 and y = 4
Step-by-step explanation:
If QRS = MNP, then QR = MN, RS = NP and QS = MP
Given
QR = 11
QS = 15
MP = 2x + 1
Recall that QS = MP
15 = 2x+1
2x = 15-1
2x = 14
x = 14/2
x = 7
Similarly
<Q = <M
<Q + <R + <S = 180
<Q + 32 + 84 = 180
<Q + 116 = 180
<Q = 180 - 116
<Q = 64 degrees
Since <M = 17y - 4
64 = 17y - 4
17y = 64+4
17y = 68
y = 68/17
y = 4
Hence x = 7 and y = 4
