Answer:

x = 675

Step-by-step explanation:

Collect terms and solve the resulting 2-step linear equation.

(x-355)+(x)+(80+2x)=2425 . . . . . given

4x -275 = 2425 . . . simplify

4x = 2700 . . . . . . . add 275

x = 675 . . . . . . . . . divide by 4

.In the coordinate x,y the point x is calledorigin abscissa line y-axis

Dmitry [639]

Answer:

The x coordinate is known as abscissa (B)

Step-by-step Explanation:

In a Cartesian plane, we learn many such terms which represent a point, or a line, or cooridnates of some points etc $.$

Such terms are:

Origin (Intersection of x axis and y-axis.)
x - axis (Horizontal line)
y - axis (Vertical line)
abscisaa (x -coordinate)
ordinate (y - coordinate)

a random sample size of 175 is drawn from a large population. The population standard deviation is 13.6. The sample mean is 87.3

navik [9.2K]

Answer:

The size of the population mean would be provided as:

mean +/- std/sqrt(sample size)

<=>

87.3 +/- 13.6/sqrt(175)

<=>

87.3 +/- 1.03

=> Option B is correct.

Hope this helps!

Evaluate the function at the indicated values. f(x)= 6x^2+ 5x -12

seropon [69]

Step-by-step explanation:

We need to find the value of the function at the indicated value.

$f(x)= 6x^2+ 5x -12$

Indicated values are : f(-7), f(0), f(6), f(7)

To find f(-7), put x = -7 in the given function

$f(-7)= 6(-7)^2+ 5(-7) -12=247$

To find f(0), put x = 0 in the given function

$f(0)= 6(0)^2+ 5(0) -12=-12$

To find f(6), put x = 6 in the given function

$f(6)= 6(6)^2+ 5(6) -12=234$

To find f(7), put x = 7 in the given function

$f(7)= 6(7)^2+ 5(7) -12=317$

Hence, this is the required solution.
