Answer:

x=-5

Step-by-step explanation:

1/2x^2+5x+25/2=0

Multiply each side by 2 to clear the fractions

2*(1/2x^2+5x+25/2)=0*2

Distribute

x^2+10x+25=0

What two numbers multiply together to give us 25 and add together to give us 10

5*5 = 25

5+5 =10

(x+5) (x+5) =0

Using the zero product property

x+5 =0  x+5 = 0

x+5-5= 0-5    x+5-5 =0-5

x=-5  x=-5

x=-5

Contact [7]

Answer:

The correct answer is - C.  11.45 ounces to 11.75 ounces.

Step-by-step explanation:

According to the empirical rule of the distribution for 68% falls under the normal curve falls within 1 standard deviation of the mean.

That is:

μ±δ

From the given information, the mean is

μ = 11.60

and the standard deviation is

δ = 0.15

We substitute the given parameters to obtain;

11.60±0.15

11.75 and 11.45

This means the lower limit is

11.45

and the upper limit is

11.75

A line of best fit predicts that when x equals 28 y will equal 27.255 but y actually equals 26 what is the residual in this case
Kobotan [32]

Answer:

The answer is -1.255 for residual value.

Step-by-step explanation:

We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:

Residual value = Observed value - predicted value

Residual value =  26 - 27.255

Residual values = -1.255
