Answer: 126 degrees

there are 360 degrees in a circle.  

Answer:

16.6667% increase

Step-by-step explanation:

Percentage Increase=Final Value−Starting Value|Starting Value|×100  

Answer:

17%

Step-by-step explanation:

The increase is calculated as the difference between yesterday's price and today's price, hence $2.45 - $2.10 = $0.35

As a fraction of yesterday's price, the fraction is [tex]\frac{0.35}{2.10}[/tex], which reduces to [tex]\frac{1}{6}[/tex].  Expressed as a decimal fraction, this is 0.16...  Shift the decimal point two places to the right to get the percentage increase of 16.6...%.

Since it said to round to the nearest tenth, rounding it makes the answer of 17.0% or 17% because since 6 is bigger than 10, we needed to round up and thus the answer is 17%.

The researcher can conclude that there is a statistically significant difference in the mean number of complaints between people living on the West Coast and those living in the Northeast.

To determine if there are geographical differences in how much people complain between the Northeast and the West Coast, we can conduct a hypothesis test.

Null hypothesis (H0): There is no difference in the mean number of complaints between the Northeast and the West Coast.

Alternative hypothesis (H1): There is a difference in the mean number of complaints between the Northeast and the West Coast.

Given the sample statistics, we can perform a two-sample independent t-test to compare the means of the two groups.

Let's calculate the test statistic and compare it to the critical value at a significance level of α = 0.05.

The West Coast sample has a mean (x1) of 9.5 and a standard deviation (s1) of 2.8, with a sample size (n1) of 20.

The Northeast sample has a mean (x2) of 15.5 and a standard deviation (s2) of 3.8, with a sample size (n2) of 20.

Using the formula for the pooled standard deviation (sp), we can calculate the test statistic (t):

sp = sqrt(((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2))

t = (x1 - x2) / (sp * sqrt(1/n1 + 1/n2))

Calculating the test statistic:

sp = sqrt(((19 * 2.8^2) + (19 * 3.8^2)) / (20 + 20 - 2)) ≈ 3.273

t = (9.5 - 15.5) / (3.273 * sqrt(1/20 + 1/20)) ≈ -4.63

Using a t-table or a statistical calculator, we can find the critical value for a two-tailed t-test with α = 0.05 and degrees of freedom (df) = n1 + n2 - 2 = 38. The critical value is approximately ±2.024.

Since the absolute value of the test statistic (4.63) is greater than the critical value (2.024), we reject the null hypothesis.

If kite is on a string that is 18 feet long, then the height of kite is (b) 9 feet.

In order to find the height of the kite, we use trigonometry. We know that the length of the string is 18 feet and the angle with the ground is 30 degrees, we use the Sine function to determine the height of the kite.

The formula to find the height is:

Height = (Length of string) × Sin(Angle),

Substituting the values,

We get,

Height = (18 feet) × Sin(30 degrees),

Using the value of Sine of 30 degrees as (0.5), we can calculate the height as :

Height = (18 feet) × (0.5),

= 9 feet

Therefore, the correct option is (b) 9 feet.

Answer:

Answer Below:

Step-by-step explanation:

The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. The fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.

(A∪B)∩C = {9, 23, 31}.

To find the intersection of the sets (A∪B) and C, we first need to determine the union of sets A and B. The union of two sets consists of all the unique elements present in both sets.

A∪B = {3, 5, 7, 9, 13, 14, 22, 23, 31}

Next, we find the intersection of the obtained union (A∪B) and set C. The intersection of two sets contains the elements that are common to both sets.

(A∪B)∩C = {9, 23, 31}

Therefore, the intersection of the sets (A∪B) and C is {9, 23, 31}. These are the elements that are present in both (A∪B) and C.

In summary, (A∪B)∩C = {9, 23, 31}.

The set A, defined as A = {∅} ∪ {⋃_{i=1}^n Ai : n ∈ ℕ, {Ai} ⊆ C, disjoint}, is proven to be an algebra on a set X.

To prove that A is an algebra, we need to show that it satisfies three conditions: (1) X ∈ A, (2) for any set A ∈ A, its complement X\A also belongs to A, and (3) for any sets A, B ∈ A, their union A ∪ B also belongs to A.

First, the empty set ∅ is included in A by definition. Second, let A be any set in A, represented as A = ⋃_{i=1}^n Ai, where {Ai} is a collection of disjoint sets from C. Then, the complement of A is X\A, which can be represented as X\A = ⋃_{i=1}^n (X\Ai). Since each Ai is in C, their complements X\Ai are also in C, implying X\A is a disjoint union of sets from C and therefore belongs to A.

Lastly, let A and B be two sets in A, represented as A = ⋃_{i=1}^n Ai and B = ⋃_{j=1}^m Bj. The union of A and B is A ∪ B = ⋃_{i=1}^n Ai ∪ ⋃_{j=1}^m Bj. Since Ai and Bj are disjoint sets from C, their union Ai ∪ Bj is also in C. Thus, A ∪ B is a disjoint union of sets from C and belongs to A.

By satisfying all three conditions, A is proven to be an algebra on X.

Answer:

b. data from our experiment

Step-by-step explanation:

The coefficients cn are related by the equation:

cn+2 = (n+1)(n+2)cn+1 + (3n-1)cn

To begin, we can substitute the expression for y into the differential equation and see if it satisfies the equation. Taking the first and second derivatives of y with respect to x, we find:

y' = ∑n=0[infinity]cnxn-1

y'' = ∑n=0[infinity]cn(n-1)xn-2

Substituting these expressions into the differential equation yields:

∑n=0[infinity]cn(n-1)xn-2 + (3x-1)∑n

=> 0[infinity]cnxn-1 - ∑n=0[infinity]cnxn+1 = 0

We can rearrange this equation to get:

∑n=0[infinity]cn(n+2)xn+1

=>  ∑n=0[infinity]cn(n-1)xn-2 + (3x-1)∑n=0[infinity]cnxn

Now, we can compare the coefficients of xn+1 on both sides of the equation to get:

cn+2 = (n+1)(n+2)cn+1 + (3n-1)cn

This is a recurrence relation for the coefficients cn. To see how it relates to the equation given in the question, we can substitute n+1 for n and simplify:

cn+3 = (n+2)(n+3)cn+2 + (3n+2)cn+1

Now we can substitute cn+1 from the original recurrence relation:

cn+3 = (n+2)(n+3)(n+1)cn+1 + (n+2)(n+3)cn + (3n+2)cn+1

Simplifying gives:

cn+3 = (n+2)(n+3)cn+2 + [(n+2)(n+3)(n+1) + 3n+2]cn+1

This is exactly the same recurrence relation as the one given in the question. Therefore, we can conclude that the coefficients cn are related by the equation:

Cos = Adjacent over Hypotenuse

Tan = Opposite over Adjacent

We can use the angle that has a measure of 31 degrees

Answer:

12.054 < 12.54

Step-by-step explanation:

The 95% confidence interval for p is  (0.47, 0.83)

Total subjects = 40

People preferring fresh brewed = 26

Calculating the sample proportion -

Sample proportion = Number of subjects preferring fresh brewed coffee / Total number of subjects

= 26 / 40

= 0.65

It is required to establish crucial values depending on chosen confidence level in order to generate the confidence interval. The z-value associated with a 97.5% cumulative probability to obtain a 95% confidence range is to be found. This is because the remaining 5% by 2 is divided to determine middle 95% of the standard normal distribution. The z-value for a 97.5% cumulative probability is around 1.96 using Table D or any other approach.

Using the formula for confidence interval -

[tex]CI = p + z x \sqrt ((px (1 - p) / n)[/tex]

Substituting the values -

[tex]CI = 0.65 ± 1.96 \sqrt{x} ((0.65 * (1 - 0.65)) / 40)[/tex]

[tex]= 0.65 ± 1.96 x \sqrt(0.2275 / 40)[/tex]

= 0.65 ± 1.96 x 0.0921

= 0.65 ± 0.1802

The value obtained for SSbetween is 20. The correct answer is (b) 20.

To calculate the sum of squares between (SSbetween) for an analysis of variance (ANOVA), we need to determine the variation between the sample means of the different treatment conditions. The formula for SSbetween is as follows:

SSbetween = n * Σ(M - m)²

where n is the sample size for each treatment condition, M is the individual treatment condition mean, and m is the overall mean.

In this case, the sample size for each treatment condition is n = 10, and the treatment condition means are M1 = 1, M2 = 2, and M3 = 3.

To calculate SSbetween, we first find the overall mean (m) by taking the average of the treatment condition means:

m = (M1 + M2 + M3) / 3

m = (1 + 2 + 3) / 3

m = 6 / 3

m = 2

Now, we can calculate SSbetween:

SSbetween = n * Σ(M - m)²

SSbetween = 10 * [(1 - 2)² + (2 - 2)² + (3 - 2)²]

SSbetween = 10 * [(-1)² + (0)² + (1)²]

SSbetween = 10 * (1 + 0 + 1)

SSbetween = 10 * 2

SSbetween = 20
