Answer:
• no
• yes
• yes
• no

Explanation:
To determine if each of the ordered pairs is a solution to y = 0, make sure the ordered pair has zero for the value of y.

• first ordered pair

(x, y)
(0, -2)

So, since this order pair has negative two for the value of y, it is not a solution.

• second pair

(x, y)
(-5, 0)

So, since this ordered pair has zero for the value of y, it is a solution.

• third ordered pair

(x, y)
(8, 0)

So, since this ordered pair has zero for the value of y, it is a solution.

• fourth solution

(x, y)
(-9, -6)

So, since this ordered pair has negative six for the value of y, it is not a solution.

Answer:

(0,-2) = No

(-5,0) = Yes

(8,0)  = Yes

(-9,-6) = No

Step-by-step explanation:

It says "solution to y = 0" so then look at the y-axis which is the second number in parenthesis.

Ex: (0, -2), y is -2 and x is 0.

Just make sure the second number is equal to 0, if not, then that is not the solution.

The number of peanuts in bags is normally distributed with a mean of 184.7 peanuts
ioda

Standard deviation = 3.3

The data point = 178

The mean = 184.7

<h2>Further Explanation</h2>

To calculate the Z-score of a bag containing 178 peanuts, we should use the formula to calculating a z-score.

The formula for calculating a Z-score is as follows

z = \frac{data Point - Mean}{Standard Deviation}

This also implies

z = \frac{178 - 184.7}{3.3}

Z= -2.03

therefore, the correct answer is -2.03

A z-score determine the number of standard deviation from the mean a data point is.

some important factors about z-score include:

  • if it is a positive z-score, it indicates the data point is above average
  • if it is a negative Z-score, it indicates the data point is below average
  • if the z-score is close to 0, it then means the data point is close to average
  • if the z-score is above 3 or below -3, it is considered to be unusual

16x² +8-7x-3x2 - 13x
liq [111]

Answer:

13x^{2}-20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

Answer:

y = 7

Step-by-step explanation:

3y+9 = 2y+16, subtract 9 from both sides, 3y = 2y + 7, then subtract 2y from both sides, y = 7, and that's the answer
