Answer:

2.4

Step-by-step explanation:

Given that :

The confidence interval = ( 7.9 , 12.7 )

The Margin of error M.O.E = Interval width/2

where;

The interval width = UCL - LCL

The interval width = 12.7 - 7.9

The interval width = 4.8

∴

The Margin of error M.O.E = 4.8/2

The Margin of error M.O.E = 2.4

Answer:

B

Step-by-step explanation:

D point is a representation of -(-3), Option D is correct.

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

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers

Every point of a number line is assumed to correspond to a real number, and every real number to a point

The points right to the integer zero are positive

The points left to the integer zero are negative

-(-3) is nothing but +3

The point D represents the 3

Hence, D point is a representation of -(-3), Option D is correct.

Hi!

Okay, so to prove that x = 4, all you have to do is insert 4 into the equation by replacing x with 4.

3x-4=8

3(4)-4=8

Now solve:

12-4=8

8=8

This is true, so x does equal 4.

Compute the derivative of y = (x² + x - 2)² using the chain rule:

dy/dx = 2 (x² + x - 2) d/dx [x² + x - 2]

dy/dx = 2 (x² + x - 2) (2x + 1)

Evaluate the derivative at x = -1 :

dy/dx (-1) = 2 ((-1)² + (-1) - 2) (2 (-1) + 1) = 4

This is the slope of the tangent line to the function at (-1, 4).

Use the point-slope formula to get the equation for the tangent line:

y - 4 = 4 (x - (-1))   →   y = 4x + 8

Answer:

Infinite number of solutions

Step-by-step explanation:

Use distributive property to eliminate the parenthesis on the left:

8 x + 12 = 16 x + 12 - 8 x

combine like terms on the right:

8x+ 12 = 8 x + 12

subtract 12 from both sides

8 x = 8 x   (notice both sides are identical)

subtract 8 x  from both sides

0 = 0

This is a true statement that takes place for whatever x-value we use in the original equation. Therefore, the equation has infinite number of solutions (any real number "x")

Answer:

12 divided by 45 is how many a minute then multiply that by 60 6 times

Step-by-step explanation: what the heck is a brainliest

Answer:

96

Step-by-step explanation:

if you divide 45 by 3 you get 15 and if you divide 12 by 3 you get four then you multiply it by 4 because there's 4 15 minutes in an hour and you do the same to the 3 since that's how many you can get in an hour and then you just multiply 16 by 6:00 because you can do 16 bread in an hour and then 16 * 6 for the amount of hours that you're baking

Answer:

23, 15, 7, 3

Step-by-step explanation:

Answer:

x = 1 y =23

x = 3 y = 15

x = 5 y = 7

x = 6 y = 3

Step-by-step explanation:

what the x is saying when it says it equals 1, 3, 5, and 6 its basically saying anytime you see an x in the problem hence the y =27 - 4x you replace the x with the number that x equals for example if x = 3 I plug three in every time I see an x in the equation like the equation y = 27 - 4x so it would be y = 27 - 4(3) (parentheses meaning 4 times 3) so it would be now y = 27 - 12 and that would be y = 15 hope this helps :)
