Answer:

The answer to your question is: Yes, it is a solution

Step-by-step explanation:

Point (-2, 3)

Line: y = 2x + 7

Process, replace the point in the line

3 = 2(-2) + 7

3 = -4 + 7

3 = 3

As we got that 3 equals 3, then the point given is a solution of the equation.

Helen [10]

The value of "x" is 14400 dollars that will make their weekly pay the same

Solution:

Given that,

Brandon is paid $235 per week plus 6% of his total sales in dollars, x, which can be represented by g (x) =235 + 0.06x

g(x) = 235 + 0.06x ----- eqn 1

Nolan is paid $667 per week plus 3% of his total sales in dollars, x, which can be represented by f(x ) = 667 + 0.03x

f(x) = 667 + 0.03x ----------- eqn 2

Determine the value of x, in dollars, that will make their weekly pay the same

For their weekly pay to be same, g(x) = f(x)

235 + 0.06x = 667 + 0.03x

Move the variables to one side and constants to other side

0.06x - 0.03x = 667 - 235

0.03x = 432

x = 14400

Thus value of "x" is 14400 dollars that will make their weekly pay the same

vova2212 [387]

Answer:

The margin of error for the 99% confidence level for this sample is ±2.23.

None of the given figures is close to the answer:

E. None of the above

Step-by-step explanation:

margin of error (ME) around the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic of the 99% confidence level (2.576)

s is the population IQ standard deviation (15)

N is the sample size (300)

Using these numbers we get:

ME= $\frac{2.576*15}{\sqrt{300} }$ ≈ 2.23
