GIVING BRAINIEST

Answers

Answer:

(3,4)

Step-by-step explanation:

Find equations of both lines

Line 1: y = 1/3x + 3

Line 2: y = 2x - 2

Set then equal to each other, then solve for x:

1/3x + 3 = 2x - 2

1/3x + 5 = 2x

x + 15 = 6x

15 = 5x

x = 3

Then sub x into one of the equations (doesn't matter which one) and solve for y

y = 2x - 2

y = 2(3) - 2

y = 6 - 2

y = 4

Solution is (3,4)

Answer:

B

Step-by-step explanation:

consider a difference of​ 20% between two values of a standard deviation to be significant. how does this computed value compare with the given standard​ deviation, ​?

Answers

According to the given statement:

The computed value is significantly less than the given value.

The correct option is B.

What is standard deviation?

The standard deviation serves as an indicator of how much a set of values can vary or be dispersed. The values are typically close to the set's mean when the standard deviation is low, while the values are dispersed over a wider range when the standard deviation is high.

According to the given information:

The  computed value, 14.5

The  standard deviation, 11.1

finding the difference :

Percentage = (14.5 - 11.1)/11.1 * 100 = 30.6%

the value  is greater than 20%. ,

so,

In comparison to the given value, the computed value is significantly lower.

Answers

Answer:

The slope of the line segment CD = 9

Hence, option 'D' is true.

Step-by-step explanation:

Given that the slope of line segment = 9

We know that two triangles would be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Given that the line segments AB and CD are both parts of the same non-vertical line. It means their slopes must be the same.

Thus, the slope of the line segment CD = 9

Hence, option 'D' is true.

Find the time it will take to drain a 2000 mL IV bag if 131 mL drained in 7 minutes. Round to the nearest minute.

Answers

The time it will take for 2000 mL to drain is 107 minutes.

How to find the time the liquid will drain?

The time it took to drain 131 mL is 7 minutes.

We have to find the time it took to drain 2000 mL.

131 millilitres drained in 7 minutes.

This means for every 7 minutes, 131 millilitres of liquid drains out.

Therefore, the time it will take for 2000 millimetres of liquid to drain can be calculated as follows:

131 mL = 7 minutes

2000 mL = ?

cross multiply

time for 2000 mL to drain = 2000 × 7 / 131

time for 2000 mL to drain = 14000 / 131

time for 2000 mL to drain = 106.870229008

time for 2000 mL to drain = 107 minutes

We have to round to the nearest minutes.

Therefore, the time it will take for 2000 mL to drain is 107 minutes.

The perimeter of the rectangle below is 54 units. What is the value of x?

Answers

Answer:

x has a value of 14.

Step-by-step explanation:

In addition to the information provided in the question, we are also told that the rectangle has a length x+1 and a width x-4.  This is all we need to know.

To work this out, we simply need to plug those numbers into the equation for the perimeter of a rectangle.  That would be p = 2l + 2w, where p is perimeter, l is length, and w is width.

We know that the resulting area (p) is equal to 54 units.  We are also given variable values for the length and width.  With that we can simply plug them into that equation and solve it for x:

[tex]p = 2l + 2w[/tex]

[tex]54 = 2(x + 1) + 2(x - 4)[/tex]

[tex]54 = 2x + 2 + 2x - 4[/tex]

[tex]54 = 4x - 2[/tex]

[tex]56 = 4x[/tex]

[tex]x = 56 / 4[/tex]

[tex]x = 14[/tex]

Answers

Answer:

The answer is below

Step-by-step explanation:

a) To complete the table of values for y = 3x - 1, we substitute the value of x into the equation and find y.

For x = -2, y = 3(-2) - 1 = -7; For x = -1, y = 3(-1) - 1 = -4

For x = 0, y = 3(0) - 1 = -1;    For x = 1, y = 3(1) - 1 = 2

For x = 2, y = 3(2) - 1 = 5;    For x = 3, y = 3(3) - 1 = 8

x:    -2      -1        0        1         2       3

y:    -7      -4       -1        2         5      8

b) The graph is drawn using geogebra online graphing calculator.

c) From the graph, When x = 2.5, y = 6.5
