The smallest central angle is 50.4 degrees, which corresponds to the candidate from party z.

To find the central angle for each candidate, we first need to calculate the proportion of voters who support each party. We can do this by dividing the number of voters who support each party by the total number of voters and multiplying the result by 360 (the total number of degrees in a circle). This will give us the central angle for each party in the pie chart.

For the candidate from party x, we have 134 supporters out of 216 voters. So the proportion of voters who support this candidate is:

134/216 = 0.62

To find the central angle, we multiply this proportion by 360:

0.62 x 360 = 223.2 degrees

So the central angle for the candidate from party x is 223.2 degrees.

Similarly, for the candidate from party y, we have 52 supporters out of 216 voters. So the proportion of voters who support this candidate is:

52/216 = 0.24

To find the central angle, we multiply this proportion by 360:

0.24 x 360 = 86.4 degrees

So the central angle for the candidate from party y is 86.4 degrees.

Finally, for the candidate from party z, we have 30 supporters out of 216 voters. So the proportion of voters who support this candidate is:

30/216 = 0.14

To find the central angle, we multiply this proportion by 360:

0.14 x 360 = 50.4 degrees

So the central angle for the candidate from party z is 50.4 degrees.

Answer:

99.5% Confidence interval = (-0.025, 0.547)

= -0.025 < p < 0.547

Step-by-step explanation:

             | A | B | C | Total

Male      | 5 | 4 | 17 | 26

Female | 6 | 2 | 15 | 23

Total     | 11 | 6 | 32 | 49

If p represent the proportion of all female students who would receive a grade of A on this test. Use a 99.5% confidence interval to estimate p to three decimal places.

All female students = 23

Female students that score an A = 6

p = (6/23) = 0.2608695652 = 0.261

Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample proportion) ± (Margin of error)

Sample proportion = (6/23) = 0.261

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error)

Critical value at 99.5% confidence interval for sample size of 23 is obtained from the t-tables since information on the population standard deviation is not known.

we first find the degree of freedom and the significance level.

Degree of freedom = df = n - 1 = 23 - 1 = 22.

Significance level for 99.5% confidence interval

(100% - 99.5%)/2 = 0.25% = 0.0025

t (0.0025, 22) = 3.119 (from the t-tables)

Standard error of the mean = σₓ = √[p(1-p)/N]

p = 0.261

N = sample size = 23

σₓ = √(0.261×0.739/23) = 0.091575

99.5% Confidence Interval = (Sample proportion) ± [(Critical value) × (standard Error)]

CI = 0.261 ± (3.119 × 0.091575)

CI = 0.261 ± 0.2856

99.5% CI = (-0.0246, 0.5466)

99.5% Confidence interval = (-0.025, 0.547)

= -0.025 < p < 0.547

The coordinates of the image if triangle ABC is translated 4 units down would be: A′(1, -6), B′(9, -6), C′(5, -2)

To translate the triangle 4 units down, we need to subtract 4 from the y-coordinate of each vertex.

Vertex A has coordinates (1, -2), so its image A' after the translation is (1, -2 - 4) = (1, -6).

Vertex B has coordinates (9, -2), so its image B' after the translation is (9, -2 - 4) = (9, -6).

Vertex C has coordinates (5, 2), so its image C' after the translation is (5, 2 - 4) = (5, -2).

Therefore, the coordinates of the vertices of triangle ABC after it is translated 4 units down are A′(1, −6), B′(9, −6), and C′(5, −2).

So, the answer is option A: A′(1, −6), B′(9, −6), C′(5, −2)..

How can you use the coordinates of the vertices of a figure to determine its image after a translation?

To determine the image of a figure after a translation, you can add or subtract the same amount from the x- and/or y-coordinates of each vertex, depending on the direction and distance of the translation.

The sample mean of the number of movies watched by 25 students is 2.8 and the approximate sample standard deviation is 1.15.

(a) The sample mean X can be calculated by taking the average of the number of movies watched by all 25 students.

Step 1: Sum up the number of movies watched by all 25 students:

\(0 * 1 + 1 * 2 + 2 * 4 + 3 * 10 + 4 * 6 + 3 * 2 = 0 + 2 + 8 + 30 + 24 + 6 = 70\)

Step 2: Divide the sum from Step 1 by the number of students (25):

70 / 25 = 2.8

So the sample mean X = 2.8

(b) The sample standard deviation s can be calculated using the formula:

\(s = \sqrt{\frac{ \sum(X - X_{mean})^2}{(n-1)} }\)

Where \(X_{mean}\) is the sample mean, n is the sample size, and Σ represents the sum of all values.

Step 1: Calculate \((X - X_{mean})^2\)for each data point and sum up the values:

\((0 - 2.8)^2 * 1 + (1 - 2.8)^2 * 2 + (2 - 2.8)^2 * 4 + (3 - 2.8)^2 * 10 + (4 - 2.8)^2 * 6 + (3 - 2.8)^2 * 2\\ = 7.84 + 3.24 + 0.64 + 9.6 + 1.44 + 7.84\\ = 31.36\)

Step 2: Divide the sum from Step 1 by (n - 1) = 24:

31.36 / 24 = 1.31

Step 3: Take the square root of the result from Step 2:

\(\sqrt{1.31} = 1.15\)

So the approximate sample standard deviation s = 1.15 (rounded to two decimal places).

Step-by-step explanation:

a. The answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. The answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

a. To represent 20 longs in base seven, we need to find the fewest number of multibase blocks required.

In base seven, we have the following conversions:

1 long = 1 unit

1 flat = 10 units

1 block = 10 flats

To represent 20 longs, we can use 2 flats (each flat representing 10 units) and 0 units since there are no remaining units.

So, the fewest number of multibase blocks required would be 2 flats.

Therefore, the answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. To represent 10 longs in base three, we need to find the fewest number of multibase blocks required.

In base three, we have the following conversions:

1 long = 1 unit

1 flat = 3 units

1 block = 3 flats

To represent 10 longs, we can use 3 flats (each flat representing 3 units) and 1 unit since there is one remaining unit.

So, the fewest number of multibase blocks required would be 3 flats and 1 unit.

Therefore, the answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

We can conclude that the resistors from Manufacturer 1 have better mean resistance than Manufacturer 2.

What is the null hypothesis?

In statistics, the null hypothesis is a statement or assumption that there is no relationship or difference between certain populations or variables. It is typically represented by the symbol H0. The null hypothesis is used as a starting point for statistical hypothesis testing, which is a method used to determine whether the null hypothesis can be rejected or not based on sample data.

Given that the specialist has purchased 35 resistors from Manufacturer 1 with a mean of 150 ohms and a standard deviation of 2 ohms, and Manufacturer 2 offers a sample of 40 resistors with a mean of 148 ohms and a standard deviation of 2.5 ohms, we can assume that the two samples are independent and normally distributed.

To compare the means of the two samples, we can use a t-test for the means of two independent samples. The t-test will allow us to determine whether the difference in means between the two samples is statistically significant, or if it could have occurred by chance.

The null hypothesis of the t-test would be that there is no difference in means between the two samples, or that the mean of the Manufacturer 1 sample is equal to the mean of the Manufacturer 2 sample. The alternative hypothesis would be that there is a difference in means, or that the mean of the Manufacturer 1 sample is not equal to the mean of the Manufacturer 2 sample.

The t-value can be calculated using the formula:

t = (x1-x2)/sqrt((s1^2/n1) + (s2^2/n2))

where x1 and x2 are the sample means, s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes.

Once the t-value is calculated, we can look up the t-value in a t-table to find the corresponding p-value. The p-value represents the probability of obtaining a t-value as extreme as the one calculated, assuming the null hypothesis is true.

If the p-value is less than the chosen significance level (usually 0.05), we would reject the null hypothesis and conclude that there is a statistically significant difference in means between the two samples

Hence, we can conclude that the resistors from Manufacturer 1 have better mean resistance than Manufacturer 2.

Answer:

A and B are exhaustive.

Step-by-step explanation:

Given

\(A = \{1,2,4\}\)

\(B = \{2,3,4,5,6\}\)

\(C =\{3,4\}\)

\(D = \{2,4,5\}\)

Solving (a): The mutually exclusive events

These are events that have no common or mutual elements

Events A to D are not mutually exclusive because each of the events have at least 1 common element with one another.

Solving (b): Exhaustive events.

Two events X and Y are said to be exhaustive if:

\(S = P(X\ n\ Y)\)

i.e. if the sample space equals the intersection of X and Y

For events A to D, we have:

\(A\ n\ B = \{1,2,3,4,5,6\}\)

and the sample space is:

\(S = \{1,2,3,4,5,6\}\)

By comparison;
