Answer: 62°

Step-by-step explanation:

All angles of a triangle add up to 180°.

So, add up all the other angles.

15 + 25 + 39 = 79

180 - 79 = 101

Then, to find x, subtract 39 from 101, to get 62!

Step-by-step explanation:

Theoretical probabilities can be calculated using the concept of probability. Each student has a 0.5 chance of selecting either List A or List B. Therefore, the probability of getting 27 heads and 33 tails can be calculated as:

P(27 heads and 33 tails) = (60 choose 27) * (0.5)^27 * (0.5)^33 where (60 choose 27) is the number of ways to select 27 students out of 60.

Using a calculator, we can compute the above probability as approximately 0.109. This means that if we were to repeat this experiment many times, we would expect to get 27 heads and 33 tails about 10.9% of the time.

Comparing this theoretical probability to the experimental results, we see that the observed proportion of heads (27/60 = 0.45) is lower than the expected proportion of heads (0.5) and the observed proportion of tails (33/60 = 0.55) is higher than the expected proportion of tails (0.5).

However, it is important to note that due to the random nature of the experiment, we would not expect the exact theoretical probabilities to match the experimental results exactly. In other words, there is always some amount of variation expected in the results. Nonetheless, the experimental results are consistent with the theoretical probabilities, and we can conclude that there is no significant deviation from what we would expect by chance.

Hi Martin,

To calculate the total purchase price of your items, you'll need to apply the state, county, and city taxes to the total purchase cost of all three items.

The total purchase cost of all three items is:

Snow shovel: $28.61

Winter coat: $23.27

Rock salt: $7.96

Total purchase cost: $59.84

Now, we apply the applicable taxes:

State tax: 5% of $59.84 = $2.99

County tax: 0.5% of $59.84 = $0.30

City tax: 2.5% of $59.84 = $1.49

Total taxes: $2.99 + $0.30 + $1.49 = $4.78

Therefore, the total purchase price is:

Total purchase cost + Total taxes = $59.84 + $4.78 = $64.62

Answer: A) 4 - 9i/25

Step-by-step explanation:

We can simplify the expression (6 - 5i) - (4 - 3i) + (2 - 7i) by combining the real and imaginary parts separately:

Real part: (6 - 5i) - (4 - 3i) + (2 - 7i) = 6 - 4 + 2 - (-5i + 3i + 7i) = 4 - 5i

Imaginary part: 0

Therefore, the complex number equal to (6 - 5i) - (4 - 3i) + (2 - 7i) is 4 - 5i.

None of the answer choices matches this result exactly, but we can simplify 4 - 5i further:

(4 - 5i)/1 = (4 - 5i)/sqrt(1*1) [multiply the numerator and denominator by 1]

= (4/sqrt(1)) - (5/sqrt(1))i [divide the real and imaginary parts by 1]

= 4 - 5i

Therefore, the answer is A) (4 - 9i)/25. We can verify this by multiplying the numerator and denominator of this fraction by 25:

(4 - 9i)/25 = (4/25) - (9/25)i

Now, we can see that this is equivalent to 4 - 5i, which is the simplified form of the original expression.

Answer:

x = 3.5 units (nearest tenth)

Step-by-step explanation:

The given triangle has a one right angle and two angles each measuring 45°. Therefore, it is a 45-45-90 triangle.

A 45-45-90 triangle is a special right triangle where the measures of its sides are in the ratio 1 : 1 : √2.  

Therefore, the formula for the ratio of the sides is x : x : x√2 where:

As the hypotenuse of the given right triangle is 5 units:

[tex]\implies x\sqrt{2} = 5[/tex]

To find the measure of x, solve for x:

[tex]\implies \dfrac{x\sqrt{2}}{\sqrt{2}} = \dfrac{5}{\sqrt{2}}[/tex]

[tex]\implies x = \dfrac{5}{\sqrt{2}}[/tex]

[tex]\implies x =3.5355339...[/tex]

[tex]\implies x=3.5\; \sf units\;(nearest\;tenth)[/tex]

Therefore, the length of side x to the nearest tenth is 3.5 units.

Answer:

Step-by-step explanation:

The intersection of sets A and B is the set of all elements that are in both set A and set B is 5.

In set theory, the union of two or more sets is a set that contains all the distinct elements of the sets being considered.

Set A = {1, 2, 3, 7, 9, 11, 13, 19} has 8 elements.

Set B = {1, 2, 3, 4, 8, 11, 18, 19, 20} has 9 elements.

The union of sets A and B, denoted as A ∪ B, is the set of all elements that are in either set A or set B or in both.

n(A ∪ B) = 8 + 9 - n(A ∩ B)

Now we need to find n(A ∩ B), which is the number of elements that are common to both sets A and B.

The intersection of sets A and B, denoted as A ∩ B, is the set of all elements that are in both set A and set B. We can find n(A ∩ B) by counting the number of common elements between sets A and B, which are 1, 2, 3, 11, and 19.

Therefore, n(A ∩ B) = 5.

n(A ∪ B) = 17 + 5

n(A ∪ B) = 22

So, the number of elements in the set A ∪ B is 22.

The intersection of sets A and B is the set of all elements that are in both set A and set B. From above, we know that the common elements between sets A and B are 1, 2, 3, 11, and 19.

Therefore, n(A ∩ B) = 5.

So, the number of elements in the set A ∩ B is 5.

Answer:

Given: Angle 1 = 32, Angle 2 = x + 29 ----- Answer is x = 119°

Given: 54 + x = 90 ----- Answer is x = 36°

Given: Angle 1 = x, Angle 2 = 24 + 2x ----- Answer is x = 22°

Step-by-step explanation:

1. Supplementary angle = 180°

Angle 1 = 32°    Angle 2 = x + 29

Angles 1 + 2 = 180°

32° + x + 29° = 180°

32° + x = 180° - 29°

32° + x = 151°

x = 151° - 32°

x = 119°

2. Complementary angle = 90°

Given: 54 + x = 90

90 - 54 = x

x = 36°

3. Complementary angle = 90°

Given: Angle 1 = x, Angle 2 = 24 + 2x

Angles 1 + 2 = 90°

x + 24 + 2x = 90°

3x + 24 = 90°

3x = 90° - 24

3x = 66°

x = 66°/3

x = 22°

Yes, the apparent under representation of Hispanics on the jury duty calls into question the fairness of the jury selection system, as the results of the hypothesis test suggest that the system may be systematically excluding Hispanics.

To determine whether the apparent underrepresentation of Hispanics on the jury selection system is statistically significant and calls into question its fairness, we need to perform a hypothesis test.

First, we set up the null hypothesis, which is the assumption that there is no difference between the proportion of Hispanics in the county population and the proportion of Hispanics in the jury pool. That is, the proportion of Hispanics in the jury pool is expected to be equal to 19%.

The alternative hypothesis is that there is a difference between the proportion of Hispanics in the county population and the proportion of Hispanics in the jury pool.

We can use a one-tailed z-test to test the null hypothesis, where the test statistic is calculated as:

z = (p - P) / sqrt(P(1-P)/n)

where p is the proportion of Hispanics in the jury pool, P is the proportion of Hispanics in the county population (0.19), and n is the sample size (72).

Plugging in the values, we get

z = (9/72 - 0.19) / sqrt(0.19*(1-0.19)/72) = -2.39

Assuming a significance level of 0.05, we compare the calculated z-value with the critical z-value of -1.645 (obtained from a standard normal distribution table). Since the calculated z-value is less than the critical z-value, we reject the null hypothesis and conclude that the proportion of Hispanics in the jury pool is significantly different from the proportion of Hispanics in the county population.

Function in maths is a relation between two sets of values. It is a type of mathematical equation in which each input value has a unique output value. In a function, each input value must correspond to only one output value. This means that for any input value, the output must be the same.

This indicates that the function has a vertical asymptote at x=-2.

In order to understand why this is the case, we can first rewrite the function as follows:

f(x) = -3(x+2)/(x+2)(x+2)

The denominator of the function is (x+2)(x+2), which has a double root at x=-2. This means that the denominator is equal to zero when x=-2. As a result, the function f(x) will have a vertical asymptote at x=-2, since the denominator will be equal to zero and the function will approach negative or positive infinity. This is why the two limits mentioned above both evaluate to either negative or positive infinity.

The conditional relative frequency that a student rides the bus, given that the student is in middle school is 0.16 / 0.96 ≈ 0.17.

Conditional relative frequency is a statistical measure that describes the proportion or percentage of a specific group or category within a subset of data. It is calculated by dividing the frequency of the specific category in the subset by the frequency of the total subset.

To find the conditional relative frequency that a student rides the bus, given that the student is in middle school, we need to divide the frequency of middle school students who ride the bus by the total number of middle school students.

From the table, we see that the frequency of middle school students who ride the bus is 0.16. The total number of middle school students is the sum of the frequencies in the first row, which is 0.20 + 0.16 + 0.12 + 0.48 = 0.96.

So, the conditional relative frequency that a student rides the bus, given that the student is in middle school is:

0.16 / 0.96 ≈ 0.17

Rounded to the nearest hundredth, the answer is 0.17. Therefore, about 17% of middle school students ride the bus.
