Can someone help me solve this question.

Answer:

A- 0.68

Step-by-step explanation:

0.58 is most likely to be the population parameter, since the sample proportions center around this value.

Option B is the correct answer.

We have,

When many large samples are taken from a population, the sample proportions should converge to the population proportion.

If the sample proportions center around a certain value, that value is likely to be a good estimate of the population proportion.

In this case,

Since the sample proportions center around 0.58, it is likely that the population proportion is also around 0.58.

Therefore,

0.58 is the most likely population parameter.

Answer:

tan R = 45/28 where ∡R=58.11° and tan S = 28/45 where ∡S=38.48°

Step-by-step explanation:

The tangent of a right triangle's angle is equal to the ratio between the triangle's opposite side to its adjacent side.

tan R = 45/28

R = tan^-1(45/28)

R = 58.11°

tan S = 28/45

S = tan^-1(28/45)

S = 38.48°

Billy purchased 9 types of one type and 16 types of another spinner.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

Billy bought 25 spinners.

Let x and y are the type of spinners.

Then, x + y = 25  {equation 1}

Some were $10 and some were $15.

10x + 15y = 295  

Simplifying,

2x + 3y = 59    {equation 2}

Multiplying 2 to the equation 1 and subtraction the equation 2,

-y = -9

y = 9

And x = 16

Therefore, each type of spinner is 9 and 16.

Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5

If this line is given to have a slope of 3/2, let us at least put it in standard form, substituting the point ( 7, 4 ) into the equation afterwards:

y = 3/2* x + b, provided b ⇒ y - intercept,

( 4 ) = 3/2 * ( 7 ) + b,

4 = 21/2 + b,

b = 4 - 10.5,

b = -6.5

Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5

Answer:

The mistake that Andy made was on step 2 when he multiplied only the variables by 12.

Step-by-step explanation:

When you're solving an equation and are multiplying one side by a number, you need to multiply the other side by that number as well to keep the equation true. Since Andy multiplied only the variables and not the constants on each side of the equation, that means the equation would no longer be valid, and solving it would provide a wrong answer.

The probability is 4/11

Step-by-step explanation:

Here, we want to get the probability of getting an even number

Using the given ratio, the total of the numbers is 4 + 7 = 11

The number of even numbers is 4

So the probability of getting an even number will be the number of even numbers divided by the total of the numbers

We have this as 4/11

Step-by-step explanation:

well, there are 4× 1-9 meaning 36 cards

Answer K= 20/x

Step-by-step explanation:

The value of k in the given linear equation is 20.

A linear equation is an equation where the variable (or variables) has the highest power of one.

Given,

310 - (30 × 7)=5 × k

⇒ 310 - 210 = 5k

⇒ 5k = 100

⇒ k = 100/5 = 20
