The ratio of SINA and COSA = 48/50 and 14/50

This is the boundary or contour length of a 2D geometric shape.

Depending on their size, multiple shapes may have the same circumference. For example, imagine a triangle made up of wires of length L.

The same wire can be used to create a square if all sides are the same length.

The length covered by the perimeter of the shape is called the perimeter. Therefore, the units of circumference are the same as the units of length.

As we can say, the surroundings are one-dimensional. As a result, you can measure in meters, kilometers, millimeters, etc.

Inches, feet, yards, and miles are other globally recognized units of circumference measurement.

According to our question,

sina = perpendicular\ hypotenuse

= 48/50

cosa= base\ perpendicular

=

14/50

Hence, The ratio of SINA and COSA = 48/50 and 14/50

There are 105 ways to select a sample of 5 keyboards from a set of 10 keyboards such that exactly 2 of the keyboards have an electrical defect.

To find the number of ways to select a sample of 5 keyboards so that exactly 2 have an electrical defect, we can use the combination formula:

 C(n,k) = n! / (k! * (n-k)!)

where n is the total number of keyboards, k is the number of defective keyboards, and C(n,k) is the number of ways to choose k defective keyboards from a total of n keyboards. Here, n = 10 (assuming there are 10 keyboards in the sample), and k = 2.

We can choose 2 defective keyboards from the total of 3 defective keyboards in C(3,2) = 3 ways. We can also choose 3 non-defective keyboards from the total of 7 non-defective keyboards in C(7,3) = 35 ways. Therefore, the total number of ways to select a sample of 5 keyboards so that exactly 2 have an electrical defect is:

C(3,2) * C(7,3) = 3 * 35 = 105

So there are 105 ways to select a sample of 5 keyboards from a set of 10 keyboards such that exactly 2 of the keyboards have an electrical defect.

Answer:

Mr Park has enough money to pay his rent.

Step-by-step explanation:

The amount of the monthly rent paid  = $1000

The account balance after depositing the paycheck = $1441.33

Now, to pay the rent,account should have more than the rent money $1000

Also, $1441.33  >  $1000

⇒ The amount in the bank after depositing the paycheck   >  The rent to be paid

Hence, Mr Park has enough money to pay his rent.

When the numerator of a certain fraction is a quarter of the value of the whole fraction, the value of the denominator of that fraction is four times the value of the numerator

The denominator of a certain fraction is a number that divides the numerator to produce a fraction. The fraction has two parts, the numerator, and the denominator. The numerator is the top part of a fraction, and the denominator is the bottom part of the fraction. When the numerator of a certain fraction is a quarter of the value of the whole fraction, the value of the denominator of that fraction can be calculated using a mathematical formula.

The mathematical formula for calculating the value of the denominator of a certain fraction is to divide the numerator by the quarter. This is because the numerator is a quarter of the value of the whole fraction. Therefore, the formula is represented as:D = N/1/4where D is the denominator, and N is the numerator of the fraction.To solve for D, we multiply both sides by the reciprocal of the fraction:1/4 = 4/1, so we have:D = N x 4/1D = 4N/

Therefore, the value of the denominator of the fraction is four times the value of the numerator. If the numerator of the fraction is 2, then the denominator of the fraction is 8. In summary, when the numerator of a certain fraction is a quarter of the value of the whole fraction, the value of the denominator of that fraction is four times the value of the numerator.

the y-coordinate must be 7 in order for the point to lie on the line.

A line in the xy-plane passes through the origin and has a slope of 1/7. Point B (1, 7) lies on the line, as the slope of the line is calculated by the equation y = mx + b, where m is the slope of the line, and b is the y-intercept. Since the line passes through the origin, the y-intercept is 0. This can be expressed as y = (1/7)x + 0

Thus, the explicit formula for the simple interest sequence A(n) = P + (n-1)(i.P) is: A(n) = P * (1 + i * (n-1)).

Simple interest is a method of calculating interest on a loan or investment where interest is charged only on the initial principal amount. In simple interest, the interest rate is applied to the original principal amount, and the interest earned remains the same throughout the entire term of the loan or investment.

by the question.

The formula for a simple interest sequence A(n) = P + (n-1) (i.P) represents the value of an investment that earns simple interest over n periods, where:

A(n) is the value of the investment after n periods.

P is the principal or initial investment

i is the interest rate per period as a decimal fraction (e.g. 0.05 for 5%)

n is the number of periods

To derive the explicit formula for A(n), we can use the formula for simple interest:

I = P * i * n

where I am the total interest earned over n periods. We can then express A(n) as:

A(n) = P + I

Substituting the expression for I, we get:

A(n) = P + P * i * (n-1)

The livable square footage of the house is 1,850 square feet.

To determine the livable square footage of the house, we need to exclude areas that are not considered living spaces. The main level of the house has 1,200 square feet and is considered livable space.

The top level has 650 square feet, but since it is not clear if the entire space is livable or if there are non-livable areas (such as an attic), we cannot assume that the entire space is livable.

Therefore, we will exclude the top level from our calculation of livable square footage. The garage is also not considered livable space, so we will exclude the 335 square feet of the garage as well.

Thus, the livable square footage of the house is 1,200 square feet (main level) + 0 square feet (top level) + 0 square feet (garage) = 1,200 square feet. Therefore, the total livable square footage of the house is 1,850 square feet.

The minimum number of people over age 32 they must include in their sample or sample size is equals to the 486.

In this question, we will use the margin of error of the 98% confidence interval for the population mean to determine the minimum sample size. We have to provide following informations for consumption of milk per week among people over age 32.

Mean = 3.1 liters

Confidence interval = 98%

Maximum/Margin of error = 0.1 liters

Standard deviations = 0.9 liters

level of significance, α = 1 - 0.98 = 0.02

or α/2 = 0.01

We have to determine the sample size for people over age 32 they must include in their sample. The margin of error is calculated by multiplying a key factor (for a certain level of confidence) by the population standard deviation. The result is then divided by the square root of the number of observations in the sample. Mathematically, [tex] ME =Z_{\frac{\alpha}{2}}\sqrt{ \frac{ σ}{n} }[/tex]

Using the Z-distribution table, value of z for 98% of confidence interval is 2.326. Substituting the known values in above formula, 0.1 = 2.326 √0.9/n

=> √0.9/n = 0.1/2.33 = 0.043
