A statistic is a characteristic of a sample, a portion of the target population. A parameter is a fixed, unknown numerical value, while the statistic is a known number and a variable which depends on the portion of the population.

Parameter Definition: a quantity or statistical measure that, for a given population, is fixed and that is used as the value of a variable in some general distribution or frequency function to make it descriptive of that.

Population: The mean and variance of a population are population parameters.

Statistic Definiton: A statistic or sample statistic is any quantity computed from values in a sample that is used for a statistical purpose. Statistical purposes include estimating a population parameter, describing a sample, or evaluating a hypothesis. The average of sample values is a statistic.

Step-by-step explanation:

usually factor and set each factor = to 0 and solve for x...so we will unsolve it.

x=5 and x=1 If you meant quartic. Quartic is a function where the leading term has a forth power. So, you can multiply the quadratic function times any other quadratic function that only gives you complex answers...the easiest would be

Step-by-step explanation:

According to the question,

p - P(70 years or older)

= 0.18

n = 4

X = no. of individuals who are older than 70 years

Now,

∴ [tex]P(X=r)=n_C_r \ p^r(1-p)^{n-r}[/tex]

∴ [tex]P(X=3)=4_C_3(0.18)^3(1-0.18)^{4-3}[/tex]

The value of the given composite functions would be,

1) (h o k)(3) = 3

2) (k o h)(-4b) = -4b

When two functions are inverses, then each will reverse the effect of the other.

For the functions f and g, we can say that;

(f o g)(x) = x and (g o f)(x) = x

For the given example,

The functions h and k are inverse functions.

Thus, for any real input value 'x',

(h o k)(x) = x and (k o h)(x) = x

So, the value of the given composite functions would be,

1) (h o k)(3) = 3

2) (k o h)(-4b) = -4b

Answer: 20

Step-by-step explanation:

Set up a proportion:

[tex]\frac{5}{6} = \frac{x}{24}[/tex]

Divide the larger denominator by the smaller one.

[tex]24[/tex] ÷ [tex]6 = 4[/tex]

Now, multiply 4 by the numerator we already have.

[tex]\frac{5}{y}[/tex] times [tex]\frac{4}{y}[/tex] = [tex]\frac{20}{y}[/tex]

Now, add the denominator back.

You get [tex]\frac{20}{24}[/tex]. Hope this helps you!

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

The equation of -4x - 10y = -7 in slope-intercept form is

y = (-2/5)x + (-7/10)

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

The equation of a line in slope intercept form is given by:

y = mx + c

m = slope

c = y-intercept

We have,

-4x - 10y = -7

Add 4x on both sides.

-4x - 10y + 4x = 7 + 4x

-10y = 7 + 4x

Multiply -1/10 on both sides.

y = -1/10 ( 7 + 4x )

y = -7/10 - (4/10)x

y = (-2/5)x + (-7/10)

Thus the equation of -4x - 10y = -7 in slope-intercept form is

y = (-2/5)x + (-7/10)

The measure of the angle PQR will be 67.4 degree.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Sides of a triangle are 13 cm , 5 cm, and 12 cm.

And, The angle PRQ = 90 degree.

Now,

Find the measure of angle PQR as;

The triangle PQR is a right triangle and PQ = 13 cm and PR = 12 cm.

Let measure of an angle PQR = θ

So, We can formulate;

sinθ = PR/PQ

sinθ = 12/13

θ = 67.4 degree.

Thus, The measure of the angle PQR will be 67.4 degree.

Answer:

2x+7

Step-by-step explanation:

Let's mark Jose's height with x. Of course, you can use any other letter or symbol.

We now need to express another value through this x. That other value we can mark with y.

This y is said to be 7 more then twice Jose's height. Jose's height is x, as we've already said, so:

y = 7 + 2•x (seven more than twice x)

That means that y = 2x+7.

B; finding the area of a circle

Step-by-step explanation:

You are most likely to encounter an irrational

number when you are finding the area of a circle

The reason is because, to find the area of a circle, we need the number pi

Mathematically as we all know, the number pi is a very popular irrational number

Since we cannot find the area of a circle without it, then we can conclude that we are most likely to come in contact with an irrational number when we find the area of a circle

Answer:

we conclude that the only option (a) is true.

Step-by-step explanation:

As we know that the multiples of 5 are the numbers which we get when we multiply by 5.

i.e.

5×1=5

5×2=10

Here, 5 and 10 are multiples of 5.

Let p and q are integers that are multiples of 5.

Let us consider

p=5

q=10

so

p+q=5+10

     = 15

A number is divisible by 5 if it ends in 5 or 0.

i.e. 15/5 = 3

so p+q is divisible by 3 as there is no remainder left.

Therefore, option (a) is true.

Checking the other options:

(b) P –q is divisible by 10

As

p=5

q=10

so

p-q=5-10

     = -5

Numbers that are divisible by 10 need to be even or divisible by 2 and divisible by 5.

As -5 is not divisible by 2.

So, option b is NOT true.

(c) P +q is divisible by 20

As

p=5

q=10

so

p-q=5+10

     = 15

Divisibility rule of  20  implies that the last two digits of the number are either  00  or divisible by  20 .

Therefore, P + q= 20 is not divisible by 20 as we don't get the whole number.

(d) P + q is divisible by 25​

As

p=5

q=10

so

p-q=5+10

     = 15

p+q=15 is not divisible by 25 as it does not end with 00, 25, 50, or 75.

so, option d is NOT correct.

Therefore, we conclude that the only option (a) is true.

B. [tex] y = 3x - 4 [/tex]

Step-by-step explanation:

First, using two points (0, -4) and (3, 5), find slope:

[tex]  m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 -(-4)}{3 - 0} = \frac{9}{3} = 3 [/tex]

Slope, m = 3

Next, determine the y-intercept, b.

The y-intercept is the value of y when x = 0. It is the point where the line intercepts the y-axis.

From the graph given, y-intercept, b, is -4.

Substitute b = -4 and m = 3 into [tex] y = mx + b [/tex].

The equation would be:

✔️[tex] y = 3x - 4 [/tex]
