The true statement is D)Census. It's pretty easy to survey all the students at a high school.

All units or participants in the target population under the survey are statistically compiled as part of the census method's process.

Population in this context refers to the total collection of observations associated with a specific study.

For instance, if university students are asked for input on the teaching staff, the latter group will be considered the study's population.

The targeted population is used to choose the various sample entities. With this approach, a predetermined number of observations that come from a bigger pool of populations are statistically analyzed.

Different types of sample methodology can be used, including basic random sampling, systematic sampling, cluster sampling, stratified sampling, and more.

By the above observations, we can conclude that This given situation is a Census as we can survey it among a collection of people that is the batch of senior students and it is easy to survey as there will be a few members of seniors in a school.

Answer:

D. y = 5x

Step-by-step explanation:

This graph shows a linear relationship between the number of sandwiches bought (x) and their cost (y). In this question, we are asked to define the relationship between x and y using an equation. Since this relationship is linear and thus has a constant of proportionality, we can represent it in the form: y = mx, where m is the ratio of the cost of sandwiches to the number of sandwiches. We can solve for m with the formula:

m = rise / run

So, the value m of the given line is:

m = 10 / 2

m = 5

Hence, the equation that displays the proportional relationship between the number of sandwiches bought (x) and their cost (y) is D. y = 5x.

To calculate std deviation in R you can create a list of values or import a CSV file to find the standard deviation.

It is simple to compute an average and standard deviation in R. The mean() and sd() functions compute the average and standard deviation, respectively.

The positive square root of the variance is the standard deviation. One of the fundamental techniques used in statistical analysis is standard deviation. Standard deviation, also known as SD or indicated by the symbol "," indicates how far a value deviates from the mean value.

A low standard deviation indicates that the values are often within a few standard deviations of the mean, whereas a large standard deviation indicates that the values are much outside of the mean.

The perimeter of the isosceles triangle is 128.8/(√35 +2) cm.

What is an isosceles triangle?

A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.

We are given that the base of an isosceles triangle is equal to 1/3 of the lateral side.

Also, the height of the base together with the height is 9.2 cm.

Let the lateral side be 'x' and the height be 'h'

So, the base is x/3

Since the height of the triangle, divides it into two right angled triangles, therefore,

x^2= h^2 + (x/6)^2

⇒h^2 = x^2 - (x/6)^2

⇒h^2 = √[x^2 - (x/6)^2]

We are given h+b=9.2 cm

So,

⇒√[x^2 - (x/6)^2] + x/3 = 9.2

⇒x√35/6 + x/3 = 9.2

⇒(x√35 +2x)/6 = 9.2

⇒x√35 +2x = 55.2

⇒x(√35 +2) = 55.2

⇒x = 55.2/(√35 +2)

So, the base is 1/3*55.2/(√35 +2) = 18.4/(√35 +2)

Perimeter = 2*55.2/(√35 +2) + 18.4/(√35 +2)

= (110.4 + 18.4)/(√35 +2)

= 128.8/(√35 +2) cm

Hence, the perimeter of the isosceles triangle is 128.8/(√35 +2) cm.

Answer:

Step-by-step explanation:

Simplify the following:

(sqrt(48))/(sqrt(42))

Rationalize the denominator. (sqrt(48))/(sqrt(42)) = (sqrt(48))/(sqrt(42))×(42^(1 - 1/2))/(42^(1 - 1/2)) = (sqrt(48)×42^(1 - 1/2))/42:

(sqrt(48)×42^(1 - 1/2))/42

Combine powers. (sqrt(48)×42^(1 - 1/2))/42 = sqrt(48)×42^((1 - 1/2) - 1):

sqrt(48)×42^((1 - 1/2) - 1)

Put 1 - 1/2 over the common denominator 2. 1 - 1/2 = 2/2 - 1/2:

sqrt(48)×42^((2/2 - 1/2) - 1)

2/2 - 1/2 = (2 - 1)/2:

sqrt(48)×42^(((2 - 1)/2) - 1)

2 - 1 = 1:

sqrt(48)×42^(1/2 - 1)

Put 1/2 - 1 over the common denominator 2. 1/2 - 1 = 1/2 - 2/2:

sqrt(48)×42^(1/2 - 2/2)

1/2 - 2/2 = (1 - 2)/2:

sqrt(48)×42^((1 - 2)/2)

1 - 2 = -1:

sqrt(48)×42^((-1)/2)

sqrt(48) = sqrt(2^4×3) = 2^2 sqrt(3):

2^2 sqrt(3) 1/sqrt(42)

2^2 = 4:

4 sqrt(3) 1/sqrt(42)

Rationalize the denominator. (4 sqrt(3))/(sqrt(42)) = (4 sqrt(3))/(sqrt(42))×(sqrt(42))/(sqrt(42)) = (4 sqrt(3) sqrt(42))/42:

(4 sqrt(3) sqrt(42))/42

The gcd of 4 and 42 is 2, so (4 sqrt(3) sqrt(42))/42 = ((2×2) sqrt(3) sqrt(42))/(2×21) = 2/2×(2 sqrt(3) sqrt(42))/21 = (2 sqrt(3) sqrt(42))/21:

(2 sqrt(3) sqrt(42))/21

sqrt(3) sqrt(42) = sqrt(3×42):

2/21 sqrt(3×42)

3×42 = 126:

(2 sqrt(126))/21

sqrt(126) = sqrt(3^2×14) = 3 sqrt(14):

In algebra, a quadratic equation is any equation that can be written in standard form as ax² + bx + c = 0, where x represents an unknown variable, and a, b, and c are known constants, where a ≠ 0. The solutions of a quadratic equation represent x values, where values stratified the equation . Quadratic formula is used to find the solution of standard equation and it can be written as, x = (- b ±√b² - 4ac)/2a .

We have, an quadratic equation,9x²- 4=0

Comparing it with standard equation ax² + bx + c = 0, we get, a = 9 , b = 0 , c = - 4

Using the quadratic formula to determine the solution of it , x = (- b ±√b² - 4ac)/2a

=> x = { -0 ±√0 - 4×9×(-4)}/2×9

  y = 250(0.96^n)

Step-by-step explanation:

You want an equation for the number of students in the senior class after n years, when it has 250 students now and decreases at 4% per year. You also want to know the number of years until the class is 100 students.

The exponential equation will have the form ...

  y = a·b^x

where 'a' is the initial value, 'b' is the growth factor, and x is the independent variable.

You have an initial value of 250, a growth factor of (1+(-4%)) = 0.96, and an independent variable of 'n', representing the number of years the population has been declining. The equation is ...

  y = 250(0.96^n)

The population will reach 100 students when n has the value that satisfies ...

  100 = 250·0.96^n

  0.4 = 0.96^n . . . . . . . . . divide by 250

  log(0.4) = n·log(0.96) . . . . . take logarithms

  n = log(0.4)/log(0.96) ≈ 22.45

The senior class will have about 100 students in 22.45 years.

Additional comment

The growth factor used in these exponential equations is (1 + growth rate), where the growth rate is the fractional change in the period of interest. The independent variable (x or n) is the number of such periods. Here, the fractional change is given as -4%, a 4% per year decrease. This tells us a period is 1 year. Of course -4% is the decimal fraction -0.04.
