Answer: Choice C  -3x+2y \ge 7

===================================================

Explanation:

The boundary line is solid, so that means we'll be dealing with "or equal to" as part of the inequality sign. The answer is between choice A and choice C because of this.

Note how the point (0,0) is not in the shaded region. This must mean that plugging x = 0 and y = 0 into the answer will lead to a false statement.

If we plug x = 0 and y = 0 into choice A, then we get...

3x-2y \le 7\\\\3(0)-2(0) \le 7\\\\0 \le 7\\\\

Which is a true statement, implying that (0,0) is in the shaded region. However, we're after a false statement, so we can rule out choice A.

The answer must be choice C

Let's plug (x,y) = (0,0) into choice C

-3x + 2y \ge 7\\\\-3(0) + 2(0) \ge 7\\\\0 \ge 7\\\\

That is false because 0 is not equal to 7, nor is it larger than 7.

This helps confirm that choice C is the answer.

James reads that 1 out of 6 eggs contains salmonella bacteria. So he never uses more than 5 eggs in cooking. If eggs do or don't
Dmitrij [34]

Answer:

B. binomial with n = 5 and p = 1/6

Step-by-step explanation:

Given that James reads that 1 out of 6 eggs contains salmonella bacteria.

So he never uses more than 5 eggs in cooking.

If eggs do or don't contain salmonella independently of each other, then

probability for any one egg to contain salmonella bacteria is the constant 1/6.

Also there are only two outcomes, either bacteria present or not.

Hence the  number of contaminated eggs when James uses 5 chosen at random has the distribution is Binomial

Here n = no of trials = no of eggs he uses = 5

Probability = 1/6

So option B is right.

Write in point-slope form an equation of the line that passes through the
QveST [7]

Answer:

y+6 = - 5(x-4)

Step-by-step explanation:

With the given information, use the point-slope formula y-y_1 = m (x-x_1) to write the equation of the line. Substitute values for the m, x_1, and y_1 to find the answer.

m represents the slope, so substitute -5 in its place. The x_1 and y_1 represent the x and y values of one point the line intersects, so substitute 4 for x_1 and -6 for y_1. This gives the following equation:

y+6 = - 5(x-4)

Plz help wit number 5 will mark Brainiest
Nana76 [90]
The function is y=2x
this means that the solutions will have the form (x, y)=(x,2x).
For example: (0,0),(1,2),(2,4),(3,6) are solutions.
The first answer choice satisfies the above conditions.
The second answer choice contains (2,2), and (2,6), both of which do not satisfy the (x,2x) condition, so it's not correct.
The third answer choice contains (4,2), which again does not satisfy (x,2x), so not the right answer.

(235) a prime number
Llana [10]

Answer:

235 is not Prime. It’s Composite.

Step-by-step explanation:

Factors of 235:

1, 5, 47, 235.

1 x 235 = 235,

47 x 5 = 235.

Prime Numbers have the number 1 and the number it's self.

This number has 4 factors, which means it’s composite,

Composite Numbers have 3 or more factors.
