Answer:

Step-by-step explanation:

This is an equilateral triangle.

The altitude bisects the 60 degree angle, so a=30

b=60 since its an interior angle of the isosceles triangle.

e = 4 since the two triangles formed by the altitude are congruent.

c = 8 since the side length is 4 + 4 = .

f = 4sqrt3 by the properties of 30 60 90 triangles.

Answer:

but A violates the overall goal of a circumference of 30ft.

and E violates the overall goal of the garden having 4 sides.

D cannot be built, because it would require 3 pieces of 9 ft (and we have only 2).

The length XY of the circle X is the radius of the circle

The length of XY is 9 units

The parameters are given as:

The length of arc is calculated using:

L = Ф/360 * 2πr

Where:

So, we have:

5π = 100/360 * 2πr

Evaluate the quotient

5π = 5/9 * πr

Divide both sides by 5π

1 = 1/9 * r

Multiply both sides by 9

r = 9

This means that

XY = r = 9

Hence, the length of XY is 9 units

Step-by-step explanation:

The expression simplified can be written as:

16m +  8

Here we want to simplify the following expression:

(8m + 4) + (8m + 4)

To simplify, we start by removing the parenthesis:

8m + 4 + 8m + 4

Now we can change the order of the terms so we get:

8m + 8m + 4 + 4

Now we can group the like terms to get:

(8m + 8m) + (4 + 4)

And simplify this to get:

16m +  8

That is the simplified expression.

The duration of the bond is approximately 0.0045 years or 1.64 days.

We can use the formula for bond price sensitivity to changes in yield to find the duration of the bond:

D = - (1/P) * (dP/dy)

where D is the duration, P is the price of the bond, y is the yield, and dP/dy is the derivative of the bond price with respect to yield.

We are given that the bond price is currently $1,050 and the yield is 7%, so we can plug these values into the formula:

P = $1,050

y = 7% or 0.07

Next, we need to find the derivative of the bond price with respect to yield, which is the percentage change in bond price divided by the percentage change in yield.

We know that if the yield increases by 20 basis points (0.20%), the price of the bond will decrease to $1,040. Using this information, we can calculate the percentage change in bond price and yield:

Percentage change in bond price = (new price - old price) / old price = ($1,040 - $1,050) / $1,050 = -0.0095 or -0.95%

Percentage change in yield = 0.20%

Using these values, we can calculate the derivative of the bond price with respect to yield:

dP/dy = (percentage change in bond price) / (percentage change in yield) = -0.0095 / 0.002 = -4.75

We can now enter each value into the duration formula as follows:

D = - (1/P) * (dP/dy) = - (1/$1,050) * (-4.75) = 0.0045 years or 1.64 days

Therefore, the duration of the bond is approximately 0.0045 years or 1.64 days.

\(Z_{1} +Z_{2}\) represents Point A i.e., 3i.

Complex numbers are the numbers that are expressed in the form of

a + ib where, a, b are real numbers and  ‘i’ is an imaginary number called “iota”. The value of i = (√-1). For example, 2+3i is a complex number, where 2 is a real number (Re) and 3i is an imaginary number (Im).

From the graph,

\(Z_{1} =3+i\)

The possible values of x are 51% < x < 59%.

When you are given various values, the range of those values is how big the difference is between the largest value and the smallest value. In other words, the range is what you get when you subtract the smallest value in the group from the largest value in the group.

Its possible values are 1, 2, 3, 4, 5, and 6; each of these possible values has a probability of 1/6. 4. The word “random” in the term “random variable” does not necessarily imply that the outcome is completely random in the sense that all values are equally likely.

Let K represent Kofi

1st paper = 45/100

2nd paper = x / 100

Mean score = ( 45 + x ) % / 2

The possible range of x = 48% < (45+X)/2 < 52%

(c) range, (d) variance, (e) standard deviation and (f) interquartile range measure variability.

Range, The range is the difference between the largest and smallest values in a dataset, indicating how spread out the data are.

Variance, The variance measures how far a set of numbers is spread out from their average. It provides a measure of how much the individual data points deviate from the mean.

Standard deviation, The standard deviation is the square root of the variance and is also a measure of how much the individual data points deviate from the mean. It is a widely used measure of variability, particularly in statistical analysis.

Interquartile range, The interquartile range (IQR) is the difference between the third and first quartiles of a dataset. It gives an idea of the spread of the middle 50% of the data and can help identify outliers.

The mean and median are measures of central tendency and do not directly measure variability.

Step-by-step explanation:

-3r-9+7=5r

-2=5r+3r

r=-2/8

hope this helped you( ꈍᴗꈍ)

Answer:

r = -1/4

Step-by-step explanation:

5r = -3(r + 3) +7

multiplying -3 with r + 3

5r = -3r - 9 +7

taking -3r on the other side of equality sign

5r + 3r = -9 + 7

8r = -2

dividing 8 by -2

r = -2/8

a) The probability that exactly one of them will be a girl = 0.3407

b) The probability that at least one of them will like the football = 0.7672

a) If we select three students then the probability that exactly one of them will be a girl

From the attached two way table we can observe that the total number of girls = 22

the total number of boys = 18

and the total number of students = 40

The possible outcomes for selecting 3 students from 40 would be,

⁴⁰C₃

Using combination formula,

⁴⁰C₃ = 40! / (3! × (40 - 3)!)

      = 9880

If there is exactly one girl then other two must be boys in the set of 3 selected students.

So, the required probability would be,

P = (²²C₁ × ¹⁸C₂) / ⁴⁰C₃

P = (22 × 153)/9880

P = 0.3407

b) The number of students like the football = 15

and the number of students who don't like the football are 40 - 15 = 25

The probability that at least one of them will like the football would be,

P = (¹⁵C₃ × ²⁵C₀ + ¹⁵C₂ × ²⁵C₁ + ¹⁵C₁ × ²⁵C₂) / ⁴⁰C₃

P = ((455 × 1) + (105 × 25) + (15 × 300)) / 9880
