Answer:

The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2) ⇒ D

Step-by-step explanation:

To solve this type of question, Form the equation of the line and substitute the x-coordinate of each ordered pair to find y, if the value of y equal to the value of the y-coordinate of the point, then the point is on the line

The form of the linear equation is y = m x + b, where

From the given figure

∵ The line passes through points (-4, 0) and (0, 4)

∴ x1 = -4 and y1 = 0

∴ x2 = 0 and y2 = 4

→ Substitute them in the rule above

∵ m = [tex]\frac{4-0}{0--4}[/tex] = [tex]\frac{4}{0+4}[/tex] = [tex]\frac{4}{4}[/tex]

∴ m = 1

∵ b is the value of y at x = 0

∵ y = 4 at x = 0

∴ b = 4

→ Substitute the values of m and b in the form of the equation above

∴ y = 1(x) + 4

∴ y = x + 4 ⇒ equation of the given line

Let us check every group

∵ The ordered pairs are (7, 3), (6, 2), (2, -2)

∵ y = x + 4

∵ x = 7

∵ y = 7 + 4 = 11

∵ y-coordinate = 3

∴ Point (7, 3) doesn't lie on the line

∵ The ordered pairs are (5, 1), (3, 7), (2, 6)

∵ x = 5

∴ y = 5 + 4 = 9

∵ y-coordinate = 1

∴ Point (5, 1) doesn't lie on the line

∵ The ordered pairs are (3, 7), (2, 6), (2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

∴ Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

∴ Point (2, 6) lies on the line

∵ x = 2

∴ y = 6

∵ y-coordinate = 2

∴ Point (2, 2) doesn't lie on the line

∵ The ordered pairs are (3, 7), (2, 6), (-2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

∴ Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

∴ Point (2, 6) lies on the line

∵ x = -2

∴ y = -2 + 4 = 2

∵ y-coordinate = 2

∴ Point (-2, 2) lies on the line

∵ The three ordered pairs lie on the line

∴ The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2)

∵ The ordered pairs are (1, 5), (-6, 2), (-7, -3)

∵ x = 1

∴ y = 1 + 4 = 5

∵ y-coordinate = 5

∴ Point (1, 5) lies on the line

∵ x = -6

∴ y = -6 + 4 = -2

∵ y-coordinate = 2

∴ Point (-6, 2) doesn't lie on the line

Answer:

95% confidence interval of the mean level of random exposure in tombs in the region.

(2746.868 , 4191.132)

Step-by-step explanation:

Step(i):-

Given sample size 'n'= 12

Mean of the sample  x⁻ = 3,469

and standard deviation of the sample 's' = 1,135

95% confidence intervals are determined by

[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} } )[/tex]

Degrees of freedom = n-1 = 12-1= 11

Step(ii):-

95% confidence intervals are determined by

[tex](3469- 2.201 \frac{1135}{\sqrt{12} } , 3469+2.201\frac{1135}{\sqrt{12} } )[/tex]

(  3469-722.132 , 3469 +722.132)

Let Carlo's age =  x

Equation: 6*x = 108

               6x = 108

Solution:

6x = 108

x = 108/6

x = 18

Carlo's age = 18 years

Answer:

Let the age of Carlo be x

Answer:

32% Decrease

Step-by-step explanation:

93 = x * 135 (divide both sides by 135 to get X alone.)

x=0.68 - Repeated (This tells us that it was paid 68% of the OG price.)

1 - 0.68 = 0.32 (We need to subtract the percent  paid from the OG price to find the percent discount.)

The percent decrease was 32% off.

5 x (23-18) x (8-4)=100

5 x (23-18) x (8-4)=100 is the Order of Operations which make it true

A number system is defined as a system of writing to express numbers.

We have to find the operations which make the value to be true.

The given numbers are 5, 23, 18, 8, and 4.

Let us use the operation addition, subtraction and addition.

Use the subtraction between twenty three and eight.

Use subtraction between eight and four.

5 x (23-18) x (8-4)=100

Hence, 5 x (23-18) x (8-4)=100 is the Order of Operations which make it true

14x+14=20x-20

-6x=-34

x=34/6=-17/3

D: -17/3​

Answer:

D

Step-by-step explanation:

x+1/x-1=14/20

so 20(x+1)=14(x-1)

20x+20=14x-14

20x-14x= -14-20

6x=-34

so x=-17/3

Answer:

The greatest number is 11

Step-by-step explanation:

Given

Dividends: 181 and 236

Remainder: 5

Required

Determine a divisor that satisfies the above condition

Let the required divisor be represented with x.

Since a remainder of 5 is expected, then x can divide (181 - 5) and (236 - 5) without remainders.

So, we have:

[tex]181 - 5 = 176[/tex]

[tex]236 - 5 = 231[/tex]

Next, we calculate the GCF of 176 and 231

[tex]176 = 2 * 2 * 2 * 2 * 11[/tex]

[tex]231 = 3 * 7 * 11[/tex]

The greatest common factor, GCT is:

[tex]GCF = 11[/tex]

Hence, the required divisor is 11
