The linear inequality for the statement " the sum of a number and 17.3 is at least −2.8" is  b + 17.3 ≥ - 2.8 which is option B

We are given that the sum of a number and 17.3 is at least −2.8 and we have to form a linear inequality from the information provided

Let the number be b

so, the sum of two numbers would be

b + 17.3

It is given that the sum should be at least - 2.8

this means the sum is either equal to - 2.8 or sum is more than -2.8

So, the linear inequality equation comes to be

b + 17.3 ≥ - 2.8

Hence, the linear inequality for the statement " the sum of a number and 17.3 is at least −2.8" is  b + 17.3 ≥ - 2.8 which is option B

The circled graph given at the end of the answer is not a function of x.

The graphs for which we choose the one which is not a function are missing, and are given at the end of the answer.

A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.

For this problem, we have that:

Answer:   Product of extremes (numbers on extreme edges) = product of means i.e., ad = bc

a, b, c, d,…. are in continued proportion means, a:b = b:c = c:d

a:b = b:c then b is called mean proportional and b2 = ac

The third proportional of two numbers, a and b, is c, such that, a:b = b:c

d is fourth proportional to numbers a, b, c if a:b = c:d

Step-by-step explanation:

Answer: GoodMorning: ) ✨ According to proportion, if two sets of given numbers are increasing or decreasing in the same ratio, then the ratios are said to be directly proportional to each other. Proportions are denoted using the symbol '::' or '='. For example, 2:5 :: 4:8 or 2/5 = 4/8.

Two values x and y are said to be directly proportional to each other when the ratio x:y always remains the same. Example : If we buy two pen for 50 Rs. It will cost us 100 Rs for four pen. Two values x and y are said to be inversely proportional to each other when the ratio x:y1 always remains the same.

use the formula: half times base times height

The mistake made by the student was using the composition f ° g(x) instead of g ° f(x). The correct form is g( f(0)) = - 9 / 2.

In this question we find two functions, with which we should perform an operation known as composition. Composition consists in substituting the input of a function by the other function. The operation is defined by the following expression:

f ° g (x) = f [g (x)]

Herein we must determine the mistake done by the student on the composition. If we know that f(x) = (3 · x - 7) / 4, g(x) = 2 · x - 1 and x = 0, then the value of g(f (0)) is:

g ° f (x) = g (f (x))

g ° f (x) = 2 · [(3 · x - 7) / 4]  - 1

g ° f (x) = (3 · x - 7) / 2 - 1

g ° f(x) = (3 / 2) · x - 7 / 2 - 1

g ° f(x) = (3 / 2) · x - 9 / 2

g ° f(0) = (3 / 2) · 0 - 9 / 2

g ° f(0) = - 9 / 2

The number of particles which are in 12 moles of any substance given the premise that; 1 mole contains 6.02×1023 particles is; 7.224 × 10²³.

It follows from the task content that 1 mole contains 6.02×1023 particles, and hence, the number of particles in 12 moles is to be determined.

On this note, it follows from proportion that since 1 mole contains 6.02×1023 particles, then, the number of particles is 12 moles is;

= 12 × 6.02 × 10²³

= 72. 24 × 10²³

= 7.224 × 10²³.

Answer:

One angle is 70 and the other angle is 110

Step-by-step explanation:

x + 40 = y

x + y = 180  Supplemental angles add to 180

Substitutes x + 40 into the second equation by y

x + x + 40 = 180  Combine like terms

2x + 40 = 180  Subtract 40 from both sides

2x = 140  Divide both sides by 2

x = 70

Substitute in 70 for x in either of the original 2 equations

x + y = 180

70 + y = 180  Subtract 70 from both sides

y = 110

m1=70

m2=110

supplementary angles are two angles that add up to 180 so all you need to do is make an equation to find the answer.

we can make m1=x and m2 = y

x is less than y by 40 degrees so y-40=x

then we use the equation x+y=180 and replace x with what we found out and solve for y.

(y-40)+y=180 ---> 2y -40 = 180 ---> 2y = 220 ---> y=110

x+y=180 ---> x+110=180 ---> x=70

New data point is residual.

When a data point is added or removed from the whole dataset, it might cause a significant change in the regression equation by either changing the slope or the relationship coefficient existing between the variables.

An influential point is one that changes the relationship existing between the dependent and the independent variables significantly in either direction.

Since the new observed data point decreases the slope of the regression line but increases the correlation coefficient existing between the independent and the dependent variable, we can probably say that the new data point is an influential point.

Thus, Option B. is correct.

When the the mean height of the 14 boys is 1.56 meters and the mean of all students is 1.515 meters then the mean height for the girls will be 1.48.

From the question, we were given total number of students as  32

But the mean can be calculated as the ratio of all the sum of all the data to the total number of data,

the total height of all students= (32*1.56)=48.48

total height of 14 boys=(14*1.56)=26.64

number of girls is (32-14)=18

The mean height for the girls will be (26.64/1118)=1.48

Therefore, When the the mean height of the 14 boys is 1.56 meters and the mean of all students is 1.515 meters then the mean height for the girls will be 1.48.

The transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units

The equation of the functions are given as

f(x)= (4x - 8)^2

g(x) = x^2

Start by stretching the function g(x) horizontally by a scale factor of 4

This is represented as

g'(x) = g(4x)

So, we have

g(4x) = (4x)^2

This gives

g'(x) = (4x)^2

Next, we translate the function down by 8 units

This is represented as

f(x) = g'(x - 8)

So, we have

f(x) = (4x - 8)^2

Hence, the transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units
