 What I've been taught, to find direction proportion: 
Ration is eggs to females.
Independent variable, x, is the female
Y, which is the eggs is the dependent variable.

What is the surface area of this triangular prism rounded to the nearest tenth? A) 48.6km2 B) 63.4 km2 C) 72.6 km2 D) 84.4 km2
Mekhanik [1.2K]

Correct option B)63.4km^2 .

<u>Step-by-step explanation:</u>

We have the following figure attached as shown below.

Now, this triangular prism have 2 similar right angled surfaces and 3 rectangular surfaces , Let's calculate area for all of them:

2 similar right angled surfaces

We know that area of triangle = \frac{1}{2} b(h)

⇒ area = \frac{1}{2} b(h)

⇒ area = \frac{1}{2} (3.6)(7.7)

⇒ area = 13.86km^{2}

But there 2 such surfaces so , area = 2(13.86) = 27.72km^2

3 rectangular surfaces

Area of rectangle = length(breadth)

⇒ area_1 = 3.6(1.8)

⇒ area_1 = 6.48km^2

⇒ area_2= 7.7(1.8)

⇒ area_2 = 13.86km^2

⇒ area_3 = 8.5(1.8)

⇒ area_2 = 15.3km^2

Total area =6.48 + 13.86 + 15.3 = 35.64km^2

Adding area of 2 similar right angled surfaces & 3 rectangular surfaces:

Area = 27.72+35.64 = 63.36km^2 = 63.4km^2

Correct option B)63.4km^2 .

Alisiya [41]

Answer:

s ≈ 105

Step-by-step explanation:

<u>Given:</u>

  • The data set: 700, 735, 680, 890, 755, 740, 670, 785, 805, 1050, 820, 750

<u>To find:</u>

  • The standard deviation of the data

<u>Steps:</u>

To find the standard deviation, first write the computational formula for the standard deviation of the sample.

{s}= \sqrt{\frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n - 1}}

Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by s . Here, we round the standard deviation to the nearest whole number.

{s} = \sqrt{10987.878787879} = 104.8231

Rounding to the nearest whole number:

s ≈ 105
