Answer:

The answer is

2 {x}^{2}  + 3x - 1 = 0

Why? Below I explain

Step-by-step explanation:

That formula has three variables a, b and c.

So, a = 2, b = 3 and c = -1

Because the formula is written like

\frac{ - b +  -  \sqrt{ {b}^{2}  - 4 \times a \times c} }{2 \times a}

Answer:

29. 15.87%

30.  4.75%

31. 0.62%

32. probability cannot be calculated (0%)

Step-by-step explanation:

We have that the formula of the normal distribution is:

z = (x - m) / sd

where x is the value we are going to evaluate, m is the mean and sd is the standard deviation

x = 16 and m = 16.5

when sd = 0.5

z = (16 - 16.5) /0.5

z = -1

Now when looking in the z table, we have that the corresponding value is 0.1587, that is, the probability is 15.87%

when sd = 0.3

z = (16 - 16.5) /0.3

z = -1.67

Now when looking in the z table, we have that the corresponding value is 0.0475, that is, the probability is 4.75%

when sd = 0.2

z = (16 - 16.5) /0.2

z = -2.5

Now when looking in the z table, we have that the corresponding value is 0.0062, that is, the probability is 0.62%

when sd = 0

z = (16 - 16.5) / 0

z = infinity

probability cannot be calculated

Answer:

(-0.5, -1)

Step-by-step explanation:

To find the midpoint add the coordinates then divide by 2

x = (2 + -1)/2

x = 1/2 = 0.5

y = (3 + -5)/2

y = -1

(-0.5, -1)

-8.1

Step-by-step explanation:

\frac{ - 4}{9} x + 2.4 = 6

<em>Times </em><em>all </em><em>by </em><em>9</em><em> </em><em>to </em><em>get </em><em>rid </em><em>of </em><em>fraction</em>

<em>- 4x + 21.6 = 54</em>

<em>Take </em><em>2</em><em>1</em><em>.</em><em>6</em><em> </em><em>away</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

<em>- 4x = 32.4</em>

<em>Divide</em><em> </em><em>by </em><em>-</em><em>4</em>

<em>x =  - 8.1</em>
