Percentage

Percentage, often referred to as percent, is a fraction of 100. Percentage means "per 100," and denotes part a total amount. For example, 45% represents 45 out of 100.

calculate the percentage-

The empirical rule states that

68% of the population lies within 1 standard deviation of the mean

95% of the population lies within 2 standard deviations of the mean

99.7% of the population lies within 3 standard deviations of the mean

Standard Deviation

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

The percentage will be illustrated in this:

P(X > 402) = P(X > 30 + 1 × 102)

Answer:

Evaluate the function for the given value of x

y=3; x=2

3x3 = 9

Given:

1. Angle B is congruent to Angle D.

2. Angle BAC is congruent to Angle DCA

To prove that triangles ABC and CDA are congruent, we first note that reflexive property means that anything is equal to itself. This means that:

Notice that both triangles share one side and we know that every side is congruent to itself. Hence, we can prove that triangles ABC and CDA are congruent by AAS Congruence Theorem as we have pairs of two congruent angles and non-included sides.

Therefore, the answer is:

In order to answer this question, we first need to understand the formula for the volume of a cylinder. The formula is V = πr²h, where V is the volume, r is the radius, and h is the height. Given that the volume of the cylinder is 1,205.76 ft³, we can use the formula to find the radius. However, we don't need to calculate the radius for this question.

Instead, we need to focus on the fact that the height of the cylinder becomes 4 times as small. This means that the new height will be 1/4 of the original height.
To find the new volume, we can substitute the new height into the formula:
V' = πr²(h/4)

Simplifying this equation, we get:
V' = (πr²h)/4
We already know that the original volume (V) is 1,205.76 ft³, so we can substitute that into the formula as well:
1,205.76 = (πr²h)

Now we can substitute this into our previous equation:
V' = (1,205.76)/4
V' = 301.44 ft³
Therefore, the new volume of the cylinder will be 301.44 ft³.

In conclusion, the volume of the cylinder will become 301.44 ft³ if the height becomes 4 times as small. This can be found by using the formula for the volume of a cylinder and substituting in the new height.

Looking up the z-value in a standard normal distribution table, we find the p-value to be 0.1473. Since this is greater than the common significance level of 0.05, we fail to reject the null hypothesis. Therefore, the answer to the given question cannot be determined as we do not know what we need to estimate the difference between.

The question seems to be incomplete as it does not mention what we need to estimate the difference between. However, based on the given information, we can calculate the sample proportions for both populations. The sample proportion for population 1 is 35/70 = 0.5, and the sample proportion for population 2 is 35/100 = 0.35.
Assuming we want to estimate the difference between the population proportions, we can use the two-sample z-test. The null hypothesis would be that the difference between the population proportions is 0, while the alternative hypothesis would be that the difference is not 0.
Using the formula for the test statistic, we can calculate the z-value as follows:
z = (p1 - p2) / sqrt(p(1-p)(1/n1 + 1/n2))
where p is the pooled sample proportion, calculated as (x1 + x2) / (n1 + n2) = 70/170 = 0.4118.
Substituting the values, we get:
z = (0.5 - 0.35) / sqrt(0.4118*(1-0.4118)*(1/70 + 1/100)) = 1.449

There is a 1/2 probability that both spinners will produce an odd number.

The probability is equal to the variety of possible outcomes.

The total number of outcomes that could occur.

For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) = 12 is what we write.

So, assume that:

Both the spinners have 1 positive number and 1 odd number.

Probability formula:

P(E) = Favourable events/Total events

Now, calculate as follows:

P(E) = Favourable events/Total events

P(E) = 2/4

P(E) = 1/2

The variance for the data set is 18.

What is a variance?

The term variance refers to a statistical measurement of the spread between numbers in a data set. More specifically, variance measures how far each number in the set is from the mean (average), and thus from every other number in the set.

Here we have to find the variance for this data set.

Given data:

The age of six grandchildren in a family is = 6, 3, 14, 11, 14, 6

The mean = 6+3+14+11+14+6/ 6

                 = 9

The variance = (6-9)² + (3-9)² + (14-9)² +(11-9)² + (14-9)² + (6-9)²/ 6

                      = 9+36+25+4+25+9/  9

Answer:

The two numbers are -4 and -12

Step-by-step explanation:

For this, we can use a little bit of algebra. Let x and y be the two numbers. We know that

x + y = -16

and

x - y = 8

Now, by adding the two equations together, we get

(x + y) + (x - y) = (-16) + 8 = 8

2 x = -8

x = -4

Since we know x = 4 now, we can substitute it into the first equation

x + y = -16

(-4) + y = -16

y = (-16) - (-4) = (-16) + 4

y = -12

The probability that at least 2 people in a room of 11 people share the same birthday, ignoring leap years and assuming each birthday is equally likely, is 0.6986.

Given: There are 11 people in a room. Ignoring leap years and assuming each birthday is equally likely, we need to determine the probability that at least 2 people in a room of 11 people share the same birthday.

To determine the probability that at least 2 people in a room of 11 people share the same birthday, we will use the formula for complementary probability, which states that P(A') = 1 - P(A), where A' is the complement of A.

So, we will find the probability that all 11 people have different birthdays, and then take its complement to find the desired probability.

Compute the probability that 11 people have different birthdaysLet E be the event that 11 people have different birthdays.

The probability that the first person has a unique birthday is 1 (since no one has celebrated his/her birthday yet).

The probability that the second person has a unique birthday is (364/365), since there are 364 days left that are different from the first person's birthday.

Similarly, the probability that the third person has a unique birthday is (363/365).

Following this trend, the probability that the eleventh person has a unique birthday is (354/365).The probability of E, that all 11 people have different birthdays, isP(E) = 1 * (364/365) * (363/365) * ... * (354/365)P(E) = 0.3014 (rounded to four decimal places).

The complement of "11 people have different birthdays" is "at least 2 share a birthday"The probability of "at least 2 share a birthday" isP(at least 2 share a birthday) = 1 - P(E)  [using the formula for complementary probability]P(at least 2 share a birthday) = 1 - 0.3014P(at least 2 share a birthday) = 0.6986

The probability that at least 2 people in a room of 11 people share the same birthday, ignoring leap years and assuming each birthday is equally likely, is 0.6986.

ople share the same birthday, ignoring leap years and assuming each birthday is equally likely, is 0.6986."

Answer:

(- 1, 7 )

Step-by-step explanation:

Given the 2 equations

3x - 4y = - 31 → (1)

- 3x - 3y = - 18 → (2)

Adding the 2 equations term by term will eliminate x, that is

0 - 7y = - 49

- 7y = - 49 ( divide both sides by - 7 )

y = 7

Substitute y = 7 into either of the 2 equations and solve for x

Substituting into (1)

3x - 4(7) = - 31

3x - 28 = - 31 ( add 28 to both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1

solution is (- 1, 7 )

any point on the line formed by the given vectors, for example, the midpoint of the line segment ba→.

x₀ = (ba→.x + bc→.x) / 2

y₀ = (ba→.y + bc→.y) / 2

ba→ and bc→, we first need to determine the bisector vector. Let's assume the slope-intercept form of the line is y = mx + b, where m is the slope and b is the y-intercept.

Find the unit vectors for the given vectors:

ba^→ = ba→ / |ba→|

bc^→ = bc→ / |bc→|

Find the sum of the unit vectors:

bisector^→ = ba^→ + bc^→

Normalize the bisector vector:

bisector^→ = bisector^→ / |bisector^→|

Find the slope of the bisector line:

m = bisector^→.y / bisector^→.x (slope = y-component / x-component)

Find the point (x₀, y₀) through which the bisector line passes:

Choose any point on the line formed by the given vectors, for example, the midpoint of the line segment ba→.

x₀ = (ba→.x + bc→.x) / 2

y₀ = (ba→.y + bc→.y) / 2

Substitute the values of m and (x₀, y₀) into the slope-intercept form:

y = m(x - x₀) + y₀

Now you have the equation of the line that bisects the angle formed by ba→ and bc→ in slope-intercept form.
