a. A statistical that estimates a population parameter

Step-by-step explanation:

A point estimate is a mathematical or statistics term that describes that is used as a means of revealing an estimated value of some parameter. It utilizes a single value, which can sometimes be the statistic mean to carry out the process of point estimation.

Hence, in this case, the correct answer is Option A: A statistical that estimates a population parameter

Step-by-step explanation:

a² - b² = (a + b) (a - b)

1)x² - 36 = x² - 6² = (x + 6)(x-6)

For any question comment me

Really sorry for the second question

Answer:

The information that we have is:

"The graph of y=-1/2x+2 is positive over the interval negative infinity and 4 and negative over the interval 4 and infinity."

Now, i guess that the question is:

"What happens on the graph when x = 4 ?"

Well, if for values of x smaller than 4 the graph is negative and for values of x larger than 4 the graph is positive, this must that the graph must cross the x-axis at some point, then with only that information, we can conclude that the graph is equal to zero when x = 4.

But we could also test it with the equation:

y = -(1/2)*x + 2

if we replace the x by a 4.

y = -(1/2)*4 + 2 = -2 + 2 = 0.

Then our previous hypothesis was correct.

Answer: $4000 + $200n + $50x

Step-by-step explanation:

From the question, we are informed that every month, Rachel gets a basic salary of $4000 and also get a bonus of $200 for each policy she sells and a bonus of $50 for each client's complaint she resolves.

The expression for her total salary for a month if she sells n policies and resolves x complaints will be:

= $4000 + ($200 × n) + ($50 × x)

= $4000 + $200n + $50x

Answer:

You have 3 pennies and your friend has 1 penny

Step-by-step explanation:

The given parameters are;

Let friend A = you

friend B = Your friend

The number of pennies with  friend A when he gives friend B 1 penny = Equal number of pennies between friend A and B

The number of pennies with friend A when he is given 1 penny by friend B = 2 times the number of pennies with friend B

Let the number of pennies with friend A = X and the number of pennies with friend B = Y, therefore, we have;

X - 1 = Y + 1.....................(1)

X + 1 = 2 × Y...................(2)

Subtracting equation (1) from equation (2), we get;

X + 1 - (X - 1) = 2·Y - (Y - 1)

X - X + 1 + 1  = 2·Y - Y + 1

2 = Y + 1

Y = 2 - 1 = 1

Y = 1

From equation (1), X - 1 = Y + 1 gives;

X - 1 = 1 + 1

X = 1 + 1 + 1 = 3

Friend A has 3 pennies and friend B has 1 penny.

Therefore, you have 3 pennies and your friend has 1 penny

Step-by-step explanation:

Step-by-step explanation:

It is given that, three oil tankers together contain 37 5/7 litres of oil.

Total volume of oil is [tex]\dfrac{264}{7}\ L[/tex]

If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

Oil in first tanker is [tex]\dfrac{157}{14}\ L[/tex]

Oil in second tanker is [tex]\dfrac{87}{7}\ L[/tex]

Oil in first and second tanker is :

[tex]\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L[/tex]

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

[tex]=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L[/tex]

Hence, this is the required solution.

Answer:

1.18 times

Step-by-step explanation:

Given that :

Surface area of Lake Victoria = 26,828 sq miles

How much larger is the surface area of lake superior than that of like Victoria?

The surface area of Lake Superior = 31,700 sq miles

Hence, taking the ratio of the surface area of the two Lakes :

Lake Superior / Lake Victoria

31,700 / 26,828

= 1.1816013

Hence, the surface area of Lake Superior is 1.18 times larger than the surface area of Lake Victoria.

Answer:

10^4

Step-by-step explanation:

lets say the number is 1.0 if you where to move the decimal to the right 4 place the number would then be 10,000.0. basically if it says 10^4 add 4 0's

Moving the decimal point to the right 4 places in a number is the same as multiplying by 10⁻⁴.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Let's consider a decimal number

2.23456 now multiply and divide by 10⁴

⇒ 2.23456 × 10⁴/10⁴

⇒ 22345.6/10⁴

⇒ 22345.6 × 10⁻⁴

Hence"Moving the decimal point to the right 4 places in a number is the same as multiplying by 10⁻⁴".

Answer:

x = 8

Step-by-step explanation:

Solve for x:

x/4 = 12/6

Hint: | Reduce 12/6 to lowest terms. Start by finding the GCD of 12 and 6.

The gcd of 12 and 6 is 6, so 12/6 = (6×2)/(6×1) = 6/6×2 = 2:

x/4 = 2

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of x/4 = 2 by 4:

(4 x)/4 = 4×2

Hint: | Cancel common terms in the numerator and denominator of (4 x)/4.

(4 x)/4 = 4/4×x = x:

x = 4×2

Hint: | Multiply 4 and 2 together.

4×2 = 8:

Answer: Choice C

[tex]y \ge 4x-5[/tex]

===============================================

Explanation:

First we need to find the equation of the boundary line. This is the line that separates the shaded region versus the non-shaded region.

The boundary line goes through (0,-5) so this is the y intercept, so b = -5

Another point on the boundary line is (1,-1). The slope of the line through (0,-5) and (1,-1) is m = 4. You can use the slope = rise/run idea or you could use the slope formula to get m = 4.

With m = 4 and b = -5, the y = mx+b equation updates to y = 4x-5

The boundary line has the equation y = 4x-5

Because it is a solid boundary line (instead of dashed) and the shading is above the boundary, this means we change the equal sign to "greater than or equal to"

Therefore we get [tex]y \ge 4x-5[/tex]

Note: a solid boundary line means that points on this boundary are included in the solution set. A dashed boundary line would mean you don't include boundary points in the solution set. So that's why there is a "or equal to" portion in the inequality sign.

Answer:

[tex]\sqrt{91}[/tex]  is irrational

Step-by-step explanation:

A rational number is a number that can be written as a ratio. Any whole number is rational number because it can be turned into a ratio.

The [tex]\sqrt{91}[/tex] is irrational.  

3 (or 3/1) is rational.

3/4 is rational

[tex]\sqrt{64}[/tex] = 8 and thus, is rational.

[tex]\sqrt{91}[/tex] = 9.539392014...... and is irrational

10.25 can be written as 41/4 so it's also rational.

This is based on my assumption you mistyped the 2 with the commas.

Answer : The value of 'x' is 8.

Step-by-step explanation :

As we are given that :

NO = 17

NP = 5x - 6

From the given diagram we conclude that NO and OP are equal and RO and OQ are equal. That means,

NO = OP and RO = OQ

That means,

NO = OP = 17

And we know that:

NP = NO + OP

So,

5x - 6 = 17 + 17

5x - 6 = 34

5x = 34 + 6

5x = 40

x = 8

Thus, the value of 'x' is 8.
