Select the correct answer. Which point is a solution of x + 2y ≤ 4? A. (2, 4) B. (1, 1) C. (3, 5) D. (-1, 5)

stira [4]

Answer:

Step-by-step explanation:

Of you put the values of c and y from B in the equation, then the result is,

$1 + 2 \times 1 \leqslant 4 \\ 1 + 2 \leqslant 4 \\ 3 \leqslant 4$

here, 3 is less than 4, which is true.

But the result will come out as greater than 4 if you put other points in the equation, which is not true for the given condition.

Enter the answer to the nearest tenth. Another home business has an average income of $1.200.00 per month with a standard deviat

Nonamiya [84]

Answer: -1.7

Step-by-step explanation:

Given : Another home business has an average income of $1.200.00 per month with a standard deviation of $100.00.

i.e. $\mu=\$1200.0$

$\sigma=\$100.00$

Let x represents the monthly income.

Since . $z=\dfrac{x-\mu}{\sigma}$

For x= 1030 , we have

$z=\dfrac{1030-1200}{100}=-1.7$

Hence, the required z-score = -1.7
