The weights, in pounds, of the cats in an animal adoption center are normally distributed. If a random sample of cats is taken and the confidence interval is (7.9,12.7), what is the margin of error?
Give a numerical response for your answer. For example, if you found that the margin of error was 2, you would enter 2.

Answers

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

Answers

Answer:

1.05 is the answer to this equation.

Answer: 1.0526315789474

Step-by-step explanation:

Change the divisor 4.75 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

500 ÷ 475 = 1.052631

and therefore:

5 ÷ 4.75 = 1.052631

Both calculated to 6 decimal places.

Hope This Helps! :)

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 :)

Find the equation of the tangent line. y=(x^2+x-2)^2 at (-1,4)​

Answers

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
