What is the value of y?

Answer:

minimum 56

Median (Q2) 65

Lower Quartile (Q1) 60

Upper Quattile (Q3) 67

Maximum 75

Step-by-step explanation:

If you notice, there are 5 distinguished points of data, and I used all the points for each thing you asked for. You just have to recognize the minimum and maximum are the largest and smallest of all the data, and there is clearly nothing outside of the range of 56-75. then Q1, Q2, and Q3 are on the box itself. The median, just like with numbers, will always be the middle line. It is not directly in the center because there are more people in the 65-75 value range than the 56-65 value range.

hope this helps!

Answer:b

Step-by-step explanation:

The requried function represented in the graph is given as y = [-x + 2,  x<1] and y = {x + 1, x ≥ 1} Option A is correct.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

The equation of the function shown in the graph is given as,
y = [-x + 2,  x<1]

y = {x + 1, x ≥ 1}

Thus, the requried function represented in the graph is given as y = [-x + 2,  x<1] and y = {x + 1, x ≥ 1} Option A is correct.

Answer:

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.

Step-by-step explanation:

Common difference is 6

Possible values of n is n > 8

(i) The nth term (Uₙ) of an arithmetic series is given by

Uₙ = a + (n-1)d        --------------------(i)

and the sum of the series is given by;

Sₙ = [tex]\frac{n}{2}[/tex](2a + (n-1)d)         ---------------------(ii)

Where;

a = first term of the series

d = common difference of the series

n = the term or number of terms to be added.

Interpret the first statement

The third term of the series is 70. i.e

n = 3

Uₙ = U₃ = 30

Substitute these values into equation (i) as follows;

=> 30 = a + (3 - 1)d

=> 30 = a + 2d

=> a = 30 - 2d          --------------------(iii)

Interpret the next statement

the sum of the first 10 terms of the series is 450. i.e

n = 10

Sₙ = S₁₀ = 450

Substitute these values into equation (ii) as follows:

=> 450 =  [tex]\frac{10}{2}[/tex](2a + (10-1)d)    

=> 450 =  5(2a + 9d)    

Divide both sides by 5

=> 90 =  2a + 9d       ---------------------------(iv)

Solve equations (iii) and (iv) simultaneously

Substitute the value of a in equation(iii) into equation (iv) and solve as follows

=> 90 = 2(30 - 2d) + 9d

=> 90 = 60 - 4d + 9d

=> 90 = 60 + 5d

=> 5d = 90 - 60

=> 5d = 30

Divide both sides by 5

=> d = 6

Therefore, the common difference, d is 6

(ii) Given

Sₙ > 350

From equation (ii), this implies that,

[tex]\frac{n}{2}[/tex](2a + (n-1)d) > 350           -------------------(v)

Let's get the value of the first term 'a'

Substitute the value of d = 6 into equation (iii) and solve as follows

=> a = 30 - 2(6)

=> a = 30 - 12

=> a = 18

Substitute the values of a and d into inequality (v) and solve

[tex]\frac{n}{2}[/tex](2(18) + (n-1)6) > 350

[tex]\frac{n}{2}[/tex](36 + 6n - 6) > 350

[tex]\frac{n}{2}[/tex](36 - 6 + 6n) > 350

[tex]\frac{n}{2}[/tex](30 + 6n) > 350

Multiply both sides by 2

n(30 + 6n) > 700

30n + 6n² > 700

6n² + 30n > 700

Divide through by 2

3n² + 15n > 350

3n(n+5) > 350

Solve the quadratic inequality

Since n specifies the number of terms to be added, it will always be a whole number. Therefore, using trial and error method, the values of n that will satisfy the above inequality will be values greater than 8. i.e

n > 8

In other words, for all values of n greater than 8, the above inequality will be satisfied.

Step-by-step explanation:

1: Streak: Streak is a word referring to the color of the streak that a rock makes when it is scraped against the unglazed side of a white ceramic tile (or, the unglazed bottom of a white coffee cup or toilet tank cover).

2: Luster: The luster of a mineral is best observed on a surface that is free of moisture, dirt, tarnish, and abrasion. Geologists in the field usually carry a rock hammer to break rocks so that their true luster and color can be observed.

3: They could both be the same mineral: The minerals pyrite and gold are always metallic yellow in color and streak (although they differ in other characteristics such as hardness).

4: The rocks contain fossils: Sedimentary rocks are most likely to contain fossils. Fossils are formed when the bodies or remnants of living organisms (plants and animals) are covered and are thus protected from predators or microbial decay. And thats exactly what a sedimentary rock is.

Answer:

(4,-5)

Step-by-step explanation:

Hi there!

The problem asks us to solve by elimination, where we will add the two equations together to clear one variable, solve for the other variable, and then substitute the value of the other variable to find the value of the first variable

here's the system:

4x-9y=61

10x+3y=25

we'll clear y to start

multiply the second equation by 3

3(10x+3y)=3(25)

30x+9y=75

  4x-9y=61

now add the equations together (the 9y's clear because one is positive and another is negative)

34x=136

divide by 34

x=4

the value of x is 4

now to find y:

substitute the value of x into either one of the equations to solve for y

if we were to do the first equation for example:

substitute x as 4 into the equation

4(4)-9y=61

multiply

16-9y=61

subtract

-9y=45

divide

y=-5

so the answer is x=4, y=-5. If you need it as a point, it's (4,-5)

Hope this helps! :D

Answer:

Part A - [tex]l_{1} + l_{2} = 5\cdot x^{2} + 7\cdot x -4[/tex], Part B - Polynomial of second degree and formed by 3 monomials, Part C - [tex]l_{3} = 5\cdot x^{3} -x^{2}-8\cdot x +1[/tex]

Step-by-step explanation:

Part A - The total length of the sides 1 and 2 is equal to the addition between respective polynomials:

[tex]l_{1} + l_{2} = (3\cdot x^{2} - 2\cdot x - 1) + (9\cdot x + 2\cdot x^{2} - 3)[/tex]

[tex]l_{1} + l_{2} = (3\cdot x^{2} + 2\cdot x^{2}) + (9\cdot x - 2\cdot x) +[(-1) + (-3)][/tex]

[tex]l_{1} + l_{2} = 5\cdot x^{2} + 7\cdot x -4[/tex]

Part B - The degree is the highest exponent of the polynomial and the classification is related to the number of monomial that make part of the algebraic expression. In this case, we conclude that resulting expression is a polynomial of second degree and formed by 3 monomials.

Part C - The length of the third side of the triangle by subtracting the expression found in part A from the polynomial of the perimeter of the triangle:

[tex]l_{3} = p - l_{1} - l_{2}[/tex]

[tex]l_{3} = (5\cdot x^{3}+4\cdot x^{2}-x-3) -(5\cdot x^{2}+7\cdot x -4)[/tex]

[tex]l_{3} = 5\cdot x^{3} + [4+(-5)]\cdot x^{2}+[(-1)+(-7)]\cdot x +[(-3)+ 4][/tex]

[tex]l_{3} = 5\cdot x^{3} -x^{2}-8\cdot x +1[/tex]

Answer:

Part A; Total length of side 1 and 2  = 5·x² + 7·x - 4

Part B; The degree of the polynomial is 2

The classification of the polynomial is a trinomial quadratic equation

Part C; 5·x³ - 4·x² - 6·x + 2

Step-by-step explanation:

The length of the sides of the rectangle are;

Side 1: 3·x² - 2·x - 1

Side 2: 9·x + 2·x² - 3

The perimeter of the rectangle is 5·x³ + 4·x² - x - 3

Part A

The given expression for the sides of the rectangle are;

Side 1: 3·x² - 2·x - 1

Side 2: 9·x + 2·x² - 3

The total length of side 1 and side 2 is given by add ing the given expressions as follows;

Total length of side 1 and 2  = 3·x² - 2·x - 1 + 9·x + 2·x² - 3 = 5·x² + 7·x - 4

Part B

The degree of the polynomial is 2 and the classification of the polynomial is a trinomial quadratic equation

Part C

Given that a rectangle rectangle consists of two pairs of equal opposite sides, we have;

The length of the third side = The perimeter - (2 × The length of side 1 + The length of side 2)

The length of the third side = 5·x³ + 4·x² - x - 3 - (2 × (3·x² - 2·x - 1) + 9·x + 2·x² - 3)

The length of the third side = 5·x³ + 4·x² - x - 3 - (8·x² + 5·x - 5)

The length of the third side = 5·x³ - 4·x² - 6·x + 2

Answer:

124 degree

Step-by-step explanation:

Since 9y + 7 and 4y+4 are supplementary,

9y + 7 + 4y + 4 = 180

13y + 11 = 180

13y = 180 - 11 = 169

y = 169/13

y = 13

Therefore, 9y + 7 = 9*13 + 7 = 124

4y + 4 = 4*13 + 4 = 56

Since Angle 6 and angle 9y + 7 are vertically opposite angles, they are equal.

angle 6 = 9y + 7

Angle 6 = 124

Answer:

15

Step-by-step explanation:

Let the smallest integer be x. The integers will be x, x+1, x+2, all the way up to x+6.

119 = 7x + (1+2+3+4+5+6)

119 = 7x + 21

7x = 98

x = 14

The second smallest integer will be x+1, so x+1 = 15.
