35 out of 50 students in a class wear glasses. What percentage of students in the class wear glasses?

Answer:

yuu okay?

Step-by-step explanation:

D   sin 85         sin 31

   ---------- =     ----------

     b                  9.3

We can use the law of sins

sin B        sin A         sin C

--------- = ----------- = ----------

b                   a            c

We do not know angle C, but we can calculate it

The angles of a triangle add to 180

A + B + C = 180

64+ 85 + C = 180

149 + C = 180

C = 180-149

C =31

sin B         sin C

--------- = ----------

b                  c

We know B =  85, C = 31, b = unknown and c = 9.3

sin 85         sin 31

---------- = ----------

b                  9.3

Answer:

if im understanding right the answer should be x = -1

Step-by-step explanation:

5x - 11 = 3x - 9

subtract 3x

2x -11 = -9

add 11

2x = -2

divide by 2

x = -1

Solution :

a). \($P(0)$\) is true

Then ,\($P(0+2)=P(2)$\) is true.

         \($P(2+2)=P(4)$\) is true

          \($P(4+2)=P(6)$\) is true.

Therefore, we see that \($P(n)$\) is true for all the even integers : \($\{0, 2,4,6,...\}$\)

b). \($P(0)$\) is true

Then ,\($P(0+3)=P(3)$\) is true.

         \($P(3+3)=P(6)$\) is true

          \($P(6+3)=P(9)$\) is true.

Therefore, we see that \($P(n)$\) is true for all the multiples of 3 : \($\{0, 3,6,9,12,...\}$\)

c). \($P(0)$\) and \($P(1)$\) is true, then \($P(0+2)=P(2)$\) is true

\($P(1)$\) and \($P(2)$\) is true, then \($P(1+2)=P(3)$\) is true.

\($P(2)$\) and \($P(3)$\) is true, then \($P(2+2)=P(4)$\) is true.

So, we observe that  \($P(n)$\) is true for all the non- negative integers : \($\{0, 1,2,3,4,5,6,...\}$\).

d). \($P(0)$\) is true,

   So, \($P(0+2)$\) and \($P(0+3)$\) is true or \($P(2)$\) and \($P(3)$\) is true.

   Now,   \($P(2)$\) is true.

Again, \($P(2+2)$\) and \($P(2+3)$\) is true or \($P(4)$\) and \($P(5)$\) is true.

   Now, \($P(3)$\) is true.

Again, \($P(3+2)$\) and \($P(3+3)$\) is true or \($P(5)$\) and \($P(6)$\) is true.

Thus,

\($P(n)$\) is true for all the non- negative integers except 1 : \($\{0, 2,3,4,5,6,...\}$\).

To find the equation of the line (line 1) that passes through the points (2,4) and is parallel to the line 3x - 2y = 18 (line 2), you can follow the steps above.

Step 1) Write the equation of line 2 in the slope-intercept form.

A general equation for the slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

So, let's isolate y in line 2:

3x - 2y = 18

3y - 18 =2y

2y = 3x - 18

y = 3/2x - 18/2

y = 3/2x - 9

Step 2) Find the slope of line 1.

Since line 1 and 2 are parallel, they have the same slope.

So,

Step 3) Find the y-intercept (b) for line 1.

The equation for line 1 is

To find b, we substitute the point (2,4) in the equation:

Step 4) Write the equation of the line.

Since you found m and b, you can write the equation of the line:

The level of measurement for the variable "Number of siblings" is a ratio, as it has a true zero point (i.e., having no siblings) and the values can be compared using ratios (e.g., having twice as many siblings as another person).

The level of measurement for a variable refers to the nature of the data and the mathematical properties that can be applied to them. The variable "Number of siblings" is a quantitative variable that can be measured on a ratio scale.

A ratio scale has a true zero point, meaning that having zero siblings is a meaningful and valid response. Additionally, the values can be compared using ratios, such as having twice as many siblings as another person.

This information is important in statistical analysis, as different levels of measurement require different methods of analysis and have different implications for interpreting the results.

The product of (3 x 107) and (2 x 107) is 6.8694 x 10^4

To find the product of (3 x 107)and (2 x 107), we can use the distributive property of multiplication which states that the product of a number and a sum is equal to the sum of the products of the number and each term in the sum. In this case, we can multiply the numbers outside the parentheses first, and then multiply the result by the common factor of 107 to simplify the expression:

(3 x 107) x (2 x 107) = 6 x (107 x 107)

Next, we can calculate the product of 107 and 107, which is 11,449:

6 x 11,449 = 68,694

In scientific notation, this can be written as:

= 6.8694 x 10^4

In a scatter plot, if all data points were aligned along a 44º angle, the correlation would be 0. The correct answer is D.

In a scatter plot, the correlation coefficient measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 1 indicates a perfect positive linear relationship, and 0 indicates no linear relationship.

When all data points are aligned along a 44º angle, it means that the points are distributed randomly and do not follow a clear linear pattern. There is no consistent increase or decrease in one variable as the other variable changes. Therefore, the correlation between the variables is 0, indicating no linear relationship or strength of association.

In other words, the angle of 44º suggests that the variables are unrelated and have no linear dependency on each other.

What is retail price?

The price at which a product's manufacturer ostensibly recommends that a retailer sell it is referred to as the list price, also known as the manufacturer's suggested retail price, recommended retail price, or suggested retail price of a product.

Given: An import/export business marks up imported merchandise by 105%.

A wicker chair imported from Singapore originally costs from the manufacturer $173.

We have to find the retail price.

Retail price = \(= 173 + 173*\frac{105}{100} \\\)

The probabilities for the hypergeometric distribution with the given parameters are:

a. P(X = 1) ≈ 0.000407

b. P(X = 6) = 0

c. P(X = 4) ≈ 0.098117

d. P(X = 0) ≈ 1.97e-05

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.

To determine the probabilities for the hypergeometric distribution with the given parameters, we can use the following formula:

P(X = k) = (choose(K, k) * choose(N-K, n-k)) / choose(N, n)

where "choose(a, b)" represents the binomial coefficient, calculated as a! / (b! * (a - b)!)

Let's calculate the probabilities:

a. P(X = 1):

P(X = 1) = (choose(20, 1) * choose(100-20, 4-1)) / choose(100, 4)

        = (20 * 80) / 3921225

        ≈ 0.000407

b. P(X = 6):

P(X = 6) = (choose(20, 6) * choose(100-20, 4-6)) / choose(100, 4)

        = (38760 * 0) / 3921225

        = 0

c. P(X = 4):

P(X = 4) = (choose(20, 4) * choose(100-20, 4-4)) / choose(100, 4)

        = (4845 * 80) / 3921225

        ≈ 0.098117

d. P(X = 0):

P(X = 0) = (choose(20, 0) * choose(100-20, 4-0)) / choose(100, 4)

        = (1 * 77) / 3921225

        ≈ 1.97e-05

Therefore:

a. P(X = 1) ≈ 0.000407

b. P(X = 6) = 0

c. P(X = 4) ≈ 0.098117

d. P(X = 0) ≈ 1.97e-05

The exact distance between (-1,-10) and (7,4) is 18 units.

To find the distance between two points in a two-dimensional plane, we can use the distance formula. The distance formula is derived from the Pythagorean theorem and states that the distance between two points (x1, y1) and (x2, y2) is given by:

distance = √[(x2 - x1)² + (y2 - y1)²]

In this case, we have the points (-1, -10) and (7, 4). Plugging these values into the distance formula, we get:

distance = √[(7 - (-1))² + (4 - (-10))²]

        = √[(7 + 1)² + (4 + 10)²]

        = √[8² + 14²]

        = √[64 + 196]

        = √260

        = 18

Therefore, the exact distance between (-1,-10) and (7,4) is 18 units.

Answer:

800x40=32000

Step-by-step explanation:

Basically its 800 40 times.

Answer:

32,000

Step-by-step explanation:

First put 800 over 40

Second, multiply the 3rd zero by the first zero of 40

Multiply the 2nd zero by the same zero of 40

Multiply 8 by 4 and the result should be 800

Then you multiply 800 by 4.

0 x 4 is 0

0 x 4 is 0

8 x 4 is 32

(Make sure you add the zero from 40)

Put it together and you get 32,000
