Find the value of x Pls help me :(

Solve the given equation. s - 19 = 12

Viktor [21]

Answer:

s=31

Step-by-step explanation:

hi again so what you are gonna do is find out the opposite of subtraction which is addition then you are gonna do the opposite..so add 19 and 12 together then your sum would be 31.....to check your answer you must subtract 31 from 19 and then you get 12....so therefore s=31

hope you are getting a better understanding!

A random sample of 10 chocolate energy bars of a certain brand has, on average, 230 calories per bar, with a standard deviation

Troyanec [42]

Answer:

The confidence interval for the true mean calorie content is

$215$

Step-by-step explanation:

In this problem we know the mean and standard deviation fo the sample, so we can compute the CI like this:

$\bar{x}-t*s/\sqrt{n}< \mu$

We need to determine t for 10-1=9 degrees of freedom and 99% confidence level. We look up in the t-table and the value for t is 3.2498.

Then we can calculate the limits of the CI:

$\bar{x}-t*s/\sqrt{n}< \mu$

Define the method equals for the window class . two windows will be considered equal if they are the same size and at the same p

Mandarinka [93]

Equating "equal" as symmetrical:

Two windows of the same size and placed in the same position is considered symmetrical. In an example where one window is placed at a certain distance from a wall and a certain distance from the floor, another window of the same size is also placed in the opposite side of the first window (based on a constant center) with the same distance from the floor and wall. The two windows can be considered equal.

The equation of line CD is Y=3X -3. Write an equation of a line perpendicular to line CD in slope intercept form that contains p

OLga [1]

(I'm learning this right now!)

y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.

Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.

y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2

An equation of a line perpendicular to line CD is y = -1/3x + 2.

Consider the function f(x) = the quantity x squared minus x minus 12 all over the quantity x plus 3. Describe the graph of this

FromTheMoon [43]

Answer:

The graph of f(x) is discontinuous at x= -3. The x and y-intercepts or he function f(x) are (4,0) and (0,-4) respectively. The graph of the function is a straight line.

Step-by-step explanation:

The given function is

$f(x)=\frac{x^2-x-12}{x+3}$
