Answer 1

Answer:

Table (4)

Step-by-step explanation:

If data in the given tables show the proportional relation then they will follow the rule,

y = kx

k = [tex]\frac{y}{x}[/tex]

where 'k' = proportionality constant

From table (1),

k = [tex]\frac{2}{1}[/tex] = 2

k = [tex]\frac{3}{2}=1.5[/tex]

But 2 ≠ 1.5

So the data in the table (1) is not proportional.

Table (2)

k = [tex]\frac{0}{2}=0[/tex]

k = [tex]\frac{2}{4}=0.5[/tex]

Therefore, data in the table is not proportional.

Table (3)

k = [tex]\frac{1}{0}[/tex] = Not defined

k = [tex]\frac{3}{2}=1.5[/tex]

Data is not proportional.

Table (4)

k = [tex]\frac{y}{x}=\frac{-6}{-2}[/tex]

= 3

k = [tex]\frac{3}{1}=3[/tex]

3 = 3

Therefore, data given in table (4) represents the proportional relationship.

A pond contains 110 fish, of which 20 are carp. If 10 fish are caught from the lake, what are the mean and variance of the number of carp among those 10?

Answers

Answer:

Mean = 1.82

Variance = 1.365

Step-by-step explanation:

We define X as the random variable that counts the number of the carp fishes that has been caught. Also we assume that all the fishes are equally likely to be caught. In that case we have that X as hypergeometric distribution.

The of the Hypergeometric Distribution and Its variance is given below.

Mean of the distribution = [tex]n*\frac{k}{N}[/tex]

Variance = [tex]\frac{n*k*(N-k)(N-n)}{N^2(N-1)}[/tex]

N= 110

k = 20

n = 10

Upon calculation we get

Mean = [tex]10*\frac{20}{110}[/tex]

= 1.82

Variance = [tex]\frac{10*20*(110-20)(110-10)}{110*110*(110-1)}[/tex] = 2*90*100/11*11*109 = 1.365

Therefore the mean is 1.82 and variance is 1.365

The mean and the variance of the number of carp are 20/11 and 180/121, respectively

The given parameters are:

Fishes = 110

Carp = 20

The probability of selecting a carp is:

p = 20/110

Simplify

p = 2/11

In a selection of 10 fishes, we have:

n = 10

The mean is:

E(x) = np

This gives

E(x) = 10 * 2/11

E(x) = 20/11

The variance is

Var(x) = E(x) * (1 - p)

So, we have:

Var(x) = 20/11 * (1 - 2/11)

Simplify

Var(x) = 20/11 * 9/11

Evaluate the product

Var(x) = 180/121

Hence, the mean and the variance of the number of carp are 20/11 and 180/121, respectively

Find the degree measure of the angle with the given radian measure. (Round your answer to one decimal place.)

Answers

Answer:

108 degrees

Step-by-step explanation:

Since we are not given the radian measure. Let the radian measure be 3π/5 rad;

Using the conversion;

πrad = 180°

3π/5 rad = x

Cross mulriply;

π * x = 180 * 3π/5

x = 180 * 3/5

x = 36 * 3

x = 108 degrees

Hence the degree measure is 108 degrees

Note that the same conversion can be used to convert other values in radians

A ratio of 3 erasers and 6 pencils could be expressed as 3:6. If the number of erasers is represented by white circles and the number of pencils is represented by black circles, which is a correct representation of the ratio?

Answers

Answer:

It'd be C.

There are 3 erasers shown and 6 pencils and to simplify the given ratio it would be 1:2

So the third representation would be the one that made the most sense.

Answer:

Option 3

Step-by-step explanation:

Ratios can be written as fractions, so 3:6=3/6. That can be simplified to 1/2, 1:2. That mesns for every eraser, there are two pencils. If white circles are erasers and black circles pencils, the correct answer will be the answer with one white circle and two black circle in each group. So the correct answer will be the third one.

The length of the sides of Δ QRS are QR = 104, QS = 468, RS = 76

Step-by-step explanation:

In ΔRQS

∵ M is the mid-point of side RQ

→ That means M divide RQ into 2 equal parts RM and MQ

∴ RM = MQ

∵ RM = 4x

∵ MQ = 52

→ Equate them

∴ 4x = 52

→ Divide both sides by 4 to get x

∴ x = 13

∵ P is the mid-point of side QS

→ That means P divide QS into 2 equal parts QP and PS

∴ QP = PS

∵ QP = 9y

∵ PS = 234

→ Equate them

∴ 9y = 234

→ Divide both sides by 9 to get y

∴ y = 26

→ Find the length of each side

∵ RQ = 52 + 52

∴ RQ = 104

∵ QS = 234 + 234

∴ QS = 468

∵ RS = 38 + 38

∴ RS = 76

∴ The length of the sides of Δ QRS are QR = 104, QS = 468, RS = 76

Note: PS = 234 is wrong because it made the length of the sides QS = 468, which could not be because the sum of any 2 sides of a triangle must be greater than the 3rd side. So check it.
