what are the solutions to the expression x^2-8x=24

Answers

Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)

Step-by-step explanation:

x^2-8x=24 <- subtract 24 from both sides

x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a

-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify

(-(-8) +/- 4sqrt(10) )/2 <- sepereate

Answers

Answer: 2 (x + y) = 29

2 (x + y - 2) = 25

y = 29/2 - x

Expanded forms:

2 x + 2 y - 4 = 25

2 x + 2 y - 29 = 0

Real solution:

y = 29/2 - x

Solution:

y = 29/2 - x

Determine the quadratic curve of best fit for the data. Then estimate what the value of will be when = −4. {(−3,2), (0,5), (1,7.3), (−1,3.3), (−6,5), (−7,7.3)} Answer choices 4.3 5.3 3.3 2.3

Answers

Answer:

The value of 'y' when x = -4 is 2.3

Step-by-step explanation:

Curve of best fit can be found by plotting the points on MS Excel and drawing a curve that goes through the points as shown in the attached graph

The equation that approximate the curve from which the y-value at a x-value of -4 can be estimated is found as follows

The general equation for a quadratic equation is y = a·x² + b·x + c

Therefore, we get;

2 = a·(-3)² + b·(-3) + c

2 = 9·a - 3·b + c

5 = 0·a + 0·b + c

5 = c

7.3 = 1·a + 1·b + c = a + b + 5

7.3 = a + b + 5

2.3 = a + b

2 = 9·a - 3·b + 5

-3 = 9·a - 3·b

Solving gives;

a = 13/40, b = 79/40

The equation of the quadratic curve is therefore;

y = (13/40)·x² + (79/40)·x + 5

When x = -4, we get;

y = (13/40)·(-4)² + (79/40)·(-4) + 5 = 2.3

When x = -4, y = 2.3

Plotting the points on MS Excel we find from the attached graph that the estimated value of 'y' when x = -4 is as calculated (2.3).

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1200 hours and a standard deviation of 35 hours. Using the empirical rule, determine what interval of hours represents the lifespan of the middle 68% of light bulbs.

Answers

Answer:

(1165, 1235) (hours)

Step-by-step explanation:

The "middle 68%" of a set of normally distributed data is that data that lies within ONE standard deviation of the mean:

(1200 - 35, 1200 + 35), or

(1165, 1235) (hours)

This is an application of the Empirical Rule.

The interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

What is the standard deviation?

It is a measurement of statistical data dispersion. The degree to which the value varies is known as dispersion.

With a mean of 1200 hours and a standard variation of 35 hours, the length of time a certain brand of light bulb lasts is typically distributed.

The data that is within one standard deviation of the mean is referred to as the "middle 68 percent" of a collection of normally distributed data:

The interval of hours represents the lifespan of the middle 68% of light bulbs is found as;

(1200 - 35)=1165

( 1200 + 35)=1235

(1165, 1235) (hours)

Hence,the interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).
