The answer is 38 degrees because the angle of HZJ is 38, its a reflection

Answer:

m<FZG= 38

Step-by-step explanation:

<JZG is a straight line equivalent to 180 degrees. Because m<HZJ is 38 degrees, m<HZG is 142 degrees because 180-38=142. Looking now at line HF, equivalent to 180 degrees, we know that m<HZG is 142 degrees. To solve for m<FZG, we use the equation 142+x=180. 180-142=x; x=38. You can also use the vertical angle theorem to solve for m<FZG.

The probability of no two people having the same birthday at a dinner party with 25 people is 0.1389.

The probability of no two people having the same birthday is calculated using the Birthday Paradox. This paradox states that if there are n people gathered in a room, the probability that at least two people have the same birthday is 1 − (365/365) * (364/365) * (363/365) *...* ((365-n+1)/365).

For a dinner party with 25 people, the probability of no two people having the same birthday is 1 − (365/365) * (364/365) * (363/365) *...* (341/365) = 0.1389.

This means that there is a 13.89% chance that no two people at the dinner party have the same birthday. The probability of no two people having the same birthday at a dinner party with 25 people is 0.1389.

For a right triangle TMR the equation that is true is -

Option 3: sin T = cos R

What is a right-angled triangle?

Any two sides of a triangle's three sides must always add up to more than the third side since a triangle is a regular polygon with three sides. This distinguishing characteristic of a triangle. A right-angle triangle is one that has angles between its two sides that equal 90 degrees.

In a right triangle, the sine of an acute angle is defined as the length of the opposite side divided by the length of the hypotenuse, and the cosine of an acute angle is defined as the length of the adjacent side divided by the length of the hypotenuse.

In triangle TMR, the right angle is at M, which means that T and R are acute angles.

Using the definitions of sine and cosine, determine which equation is true -

1. sin M = cos T

The angle M is the right angle, which means that its sine is 1 and its cosine is 0.

Therefore, this equation is false.

sin R = cos R

2. The sine and cosine of the same angle cannot be equal, except in the case of a 45° angle where both sine and cosine are equal to 1/√2.

Therefore, this equation is false.

3. sin T = cos R

The angle T is the acute angle opposite the side TR, and the angle R is the acute angle adjacent to the side TR.

Therefore, this equation is true.

4. sin T = cos M

The angle M is the right angle, which means that its cosine is 0.

Therefore, this equation is false.

If researchers use statistical tests and determine that there is a low probability that their experimental results occurred purely by chance, then their results are considered statistically significant.

Statistically significant results suggest that the observed effects in the experimental group are unlikely to have happened by chance and are likely to reflect a real effect of the treatment or intervention being tested.

However, it's important to note that statistical significance does not necessarily mean practical significance or real-world importance. For example, a small effect may be statistically significant but still not large enough to have practical implications.

Additionally, it's important to be aware of potential sources of error and bias in the experimental design and data analysis, and to consider the results in the context of other relevant evidence. Statistical significance should not be used as the sole criterion for accepting or rejecting research results, and should always be accompanied by a thorough evaluation of the quality of the evidence and the implications of the results.

The three consecutive integers are 52, 53, 54, if the sum of the first two is 51 more than the third integer.

Consecutive Integer:

An integer is the number zero (0), a positive natural number (1, 2, 3, etc.), or a negative integer with a minus sign (−1, −2, −3, etc.). A negative number is the additive reciprocal of the corresponding positive number. In math language, the set of integers is often written as bold Z.

Consecutive integers are integers that follow each other in a regular counting pattern. When listing consecutive integers in a sequence, the difference between them is always fixed because there are no skipped digits between them. Consecutive integers are integers that follow each other in ascending order. The Sequential Integer Formula helps to find these integers for a given number or to determine whether a series of integers are consecutive.

According to the Question:

Let the three consecutive integers are

x , x+1, x+2

A 95% confidence interval for the estimated proportion of Canadians who refused the H1N1 vaccination can be calculated as follows:

Let p be the true proportion of Canadians who refused the vaccination.

The sample proportion is estimated by:

p_hat = 700 / 1000 = 0.7

The standard error of the sample proportion is:

SE = sqrt(p_hat * (1 - p_hat) / 1000) = sqrt(0.7 * 0.3 / 1000) = 0.0247

Using a normal approximation and a z-score of 1.96 (corresponding to a 95% confidence level), the confidence interval can be calculated as:

p_hat +/- z * SE = 0.7 +/- 1.96 * 0.0247 = [0.6511, 0.7489]

   iii. probability of having At least one dry day is 0.83.

b)i. The probability of having Three rainy days is 0.1447.

ii. The probability of having Exactly one dry day is 0.1881

iii. The probability of having At most two rainy days is 0.35

a) On two consecutive days, the probability of having:

i. Two rainy days: The probability of two rainy days can be found by multiplying the probabilities of rain on each day, given that the previous day was rainy. In this case, the probability of two rainy days is 0.2 * 0.85 = 0.17.

ii. Exactly one rainy day: There are two ways to have exactly one rainy day in two consecutive days: either the first day is rainy and the second day is dry, or the first day is dry and the second day is rainy. The total probability of having exactly one rainy day is the sum of these two probabilities, which can be calculated as:

P(rainy day first) * P(dry day second) + P(dry day first) * P(rainy day second) = 0.2 * 0.9 + 0.8 * 0.1 = 0.18

iii. At least one dry day: To find the probability of at least one dry day, we can subtract the probability of two rainy days from 1, since the only possibility in which there is no dry day is if both days are rainy:

1 - P(two rainy days) = 1 - 0.17 = 0.83

b) On three consecutive days, the probability of having:

i. Three rainy days: The probability of three rainy days can be found by multiplying the probabilities of rain on each day, given that the previous day was rainy. In this case, the probability of three rainy days is 0.2 * 0.85 * 0.85 = 0.1447.

ii. Exactly one dry day: To have exactly one dry day in three consecutive days, we need two rainy days followed by a dry day, or a rainy day followed by two dry days, or two dry days followed by a rainy day. The total probability of having exactly one dry day can be calculated as:

P(rainy day first, rainy day second, dry day third) + P(rainy day first, dry day second, dry day third) + P(dry day first, rainy day second, rainy day third)

= 0.2 * 0.85 * 0.9 + 0.2 * 0.9 * 0.9 + 0.8 * 0.1 * 0.1 = 0.1881

iii. At most two rainy days: To find the probability of at most two rainy days, we need to add up the probabilities of two rainy days and one rainy day.

P(at most two rainy days) = P(two rainy days) + P(one rainy day) = 0.17 + 0.18 = 0.35

So, the probability of having at most two rainy days in three consecutive days is 0.35.

Using the double angle property of the trigonometric functions the value of tan 2θ = 4/3.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

Given that the value of cos θ = 2√5 / 5.

The cosine is given as:

Cos θ = adjacent side / Hypotenuse

So, the value of adjacent side = 2√5 and the value of hypotenuse = 5.

To find the value of opposite side we use the Pythagorean theorem:

a² + b² = c²

a² + (2√5)² = (5)²

a² + 4(5) = 25

a² = 25 - 20

a = √5

Now, the value of tan θ = opposite side / adjacent side so,

tan θ = √5 / 2√5 = 1/2

The tan 2θ is given as:

tan 2θ = 2(tan θ) / 1 - tan² θ

Substituting the value of tan θ:

tan 2θ = 2(1/2) ÷ (1 - (1/2)²)

tan 2θ = 1 ÷ (3/4)

tan 2θ = 4/3

Hence, using the double angle property of the trigonometric functions the value of tan 2θ = 4/3.

a) The experimental probability that the pointer lands in section 5 is 7.5%

b) The theoretical probability that the pointer lands in section 5 is 10%.

c)  The actual number of times is lower than the expected number, so we can say that the spinner landed in section 5 less often than expected.

a. Experimental probability:

The experimental probability is found by dividing the number of times the spinner lands in section 5 by the total number of spins.

In this case, the spinner landed in section 5 3 times in 40 spins, so the experimental probability is:

Experimental probability = 3/40 = 0.075 or 7.5%

b. Theoretical probability:

The theoretical probability is the expected probability based on the assumption that the spinner is fair and each section has an equal chance of being selected.

With 10 equal sections, the theoretical probability that the spinner lands in section 5 is:

Theoretical probability = 1/10 = 0.1 or 10%

c. Comparison between actual and expected:

The actual number of times the spinner landed in section 5, 3, is compared to the expected number of times, 4 (based on the theoretical probability of 10% and 40 spins).

The actual number of times is lower than the expected number, so we can say that the spinner landed in section 5 less often than expected.

Answer: Bottom Left Corner, No Shading on the base.

Step-by-step explanation: Took the test

(a) To find the product of -2x^3+x and x^3-3x-4, we can use the distributive property of multiplication:

(-2x^3 + x)(x^3 - 3x - 4)

= -2x^3(x^3) - 2x^3(-3x) - 2x^3(4) + x(x^3) - x(-3x) - x(4)

= -2x^6 + 6x^4 - x

= -2x^6 + 6x^4 - x

Therefore, the product of -2x^3+x and x^3-3x-4 is -2x^6 + 6x^4 - x.

(b) No, the product of 2x^3+x-5 and x^3-3x-4 is not equal to the product of x^3-3x-4 and -2x^3+x-5. This is because the order of the factors in a multiplication expression affects the outcome. When we expand both products using the distributive property, we get different expressions:

(2x^3 + x - 5)(x^3 - 3x - 4) = 2x^6 - 5x^3 - 3x^2 - 17x + 20

(x^3 - 3x - 4)(-2x^3 + x - 5) = -2x^6 + 11x^4 + 13x^3 - 3x^2 - x + 20

So the expanded expressions are not equal. Therefore, the two products are not equal.
