In a large county in Central Pennsylvania, 42% of all registered voters are Democrats and 53% are Republicans. What is the probability a randomly selected voter is affiliated with some other party?
Answers
Answer:
Probability [Randomly selected voter affiliated with other party] = 1/20
Step-by-step explanation:
Given:
Percentage of Democrats voters = 42%
Percentage of Republican voters = 53%
Find:
Probability [Randomly selected voter affiliated with other party]
Computation:
Percentage of other party voters = 100% - [Percentage of Democrats voters + Percentage of Republican voters]
Percentage of other party voters = 100% - [42% + 53%]
Percentage of other party voters = 100% - 95%
Percentage of other party voters = 5%
Probability [Randomly selected voter affiliated with other party] = Percentage of other party voters / 100%
Probability [Randomly selected voter affiliated with other party] = 5% / 100%
Probability [Randomly selected voter affiliated with other party] = 1/20

Answers
Answer:
Measure of the major arc OQN = 292°
Step-by-step explanation:
Measure of the major arc OQN = 360° - m(arc ON)
By the definition of central angle subtended at the center by the arc,
Measure of arc ON = Central angle subtended by the arc
= 38°
Now measure of the major arc OQN = 360° - 38°
= 292°

Answers
Complete question :
A data set includes data from student evaluations of courses. The summary statistics are nequals92, x overbarequals4.09, sequals0.55. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
Answer:
H0 : μ = 4.25
H1 : μ < 4.25
T = - 2.79
Pvalue =0.0026354
we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%
Step-by-step explanation:
Given :
n = 92, xbar = 4.09, s = 0.55 ; μ = 4.25
H0 : μ = 4.25
H1 : μ < 4.25
The test statistic :
T = (xbar - μ) ÷ s / √n
T = (4.09 - 4.25) ÷ 0.55/√92
T = - 0.16 / 0.0573414
T = - 2.79
The Pvalue can be obtained from the test statistic, using the Pvalue calculator
Pvalue : (Z < - 2.79) = 0.0026354
Pvalue < α ; Hence, we reject the Null
Thus, we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%
Answer:
Step-by-step explanation:
The null and alternative hypotheses are:
Null hypothesis: The population mean of student course evaluations is equal to 4.25.
Alternative hypothesis: The population mean of student course evaluations is not equal to 4.25.
The significance level is 0.01, so the test will be a two-tailed test.
The test statistic is calculated as:
t = (x - μ) / (s / √n) = (4.18 - 4.25) / (0.54 / √97) = -2.63
The degrees of freedom for the t-distribution is n-1 = 96. Using a t-table or a calculator, the P-value for a two-tailed test with 96 degrees of freedom and a t-value of -2.63 is approximately 0.010.
Since the P-value (0.010) is less than the significance level (0.01), we reject the null hypothesis. We have sufficient evidence to conclude that the population mean of student course evaluations is not equal to 4.25.
In other words, the data provides strong evidence to suggest that the average student course evaluation rating is significantly lower than 4.25.
Please answer if you are SURE.

Step-by-step explanation:
The standard form equation for a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where
(h, k) is the center and r is the radius.
Match up the point (-1, 5) with (h, k) to see that h = -1 and k = 5.
x - h = x - (-1) = x + 1
y - k = y - 5

4. Which of the following describes all the solutions of -4x + 2y > 12 when y = 4?
A x < -1
B X > -1
CX-3
D x < 3
Answers
Answer:
Option B is correct
Step-by-step explanation:
Given data
We are given the expression
-4x + 2y > 12
We want to substitute y=4 into the expression
-4x + 2(4) > 12
-4x + 8 > 12
-4x> 12-8
-4x> 4
divide both sides by -4
x> 4/-4
x>-1

What is the missing number?
Answers
Answer:
12
Step-by-step explanation:
The missing number is the y-intercept (b) of the table of values given.
Since we already know from the equation that the slope (m) = -³/2, therefore to find y-intercept (b) substitute the coordinates of a pair of value, say (x, y) = (4, 6), and m = -³/2 into y = mx + b
Thus,
6 = -³/2(4) + b
6 = -6 + b
6 + 6 = b
b = 12
The missing number is 12.
Which will give you:
