1/4 divided by 3 = 1/4 / 3/1 -1/4*1/3 = 1/12
6.708/76 = 6708/78000  if you do the work it would be about 5-6 lines of work but the answer is .086

1/4 divided by 3. Dividing by a number is the same as multiplying by its reciprocal. 
So it's the same as 1/4 * 1/3. And when multiplying fractions you just multiply the numerator and denominator of each straight across.
(1*1)/(4*3) = 1/12

6.708 / 78. I would just type it into the calculator. You get 0.086

In the last chapter, we looked at three outliers arising from a plot of Average Wind Speed by Month in the Hopkins Forest. Each
Aloiza [94]

Answer:

Step-by-step explanation:

Hello!

We have the information of the average wind speed for three months:

February:

Mean: 2.324

SD: 1.577

Otlier: 6.73 mph

June:

Mean: 0.857

SD: 0.795

Otlier: 3.93 mph

August

Mean: 0.63

SD: 0.597

Outlier: 2.53mph

a)

Z=  X - μ ~N(0;1)

δ

Z_{February}= \frac{6.73 - 2.324}{1.577}

Z_{Februar}= 2.793 ≅2.79

Z_{June}= \frac{3.93 - 0.857 }{0.795}

Z_{June}= 3.87

Z_{August}= \frac{2.53 - 0.63}{0.597}

Z_{Augus}= 3.182 ≅ 3.18

b)

Comparing the three Z-scores you can say that the strongest wind event was in June. The number obtained means that is the furthest one in relation to the mean.

Tyrone factored the polynomial completely. What is the value of b? 12x^4+30x^3+4x^2+10x
Arlecino [84]
The value of B = 2x (3x^2 + 1) (2x + 5)

Given: 12x^4 + 30x^3 + 4x^2 + 10x

Req'd: B = ?

Sol'n:

*use elimination

solving for B:

= 2x (6x^3 +15x^2 + 2x +5)
= 2x (3x^2(2x + 5 +2x +5)
= 2x (3x^2 + 1) (2x + 5)

Identify the hypotenuse.<br><br>A. MN<br>B. LN​
ohaa [14]

Answer:

The hypotenuse is line segment MN.

Step-by-step explanation:

*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^

The angle 90 degrees (also represented by the red line on angle L) always always is opposite to the hypotenuse. Since angle L is 90 degrees, it is opposite of the hypotenuse, which is MN.
