Answer:
[0.4,4]

Explanation:
The get the values of y belonging to the given interval, we will simply solve the following inequality:
-5 ≤ 5y - 7 <span>≤ 13
-5 + 7 </span>≤ 5y <span>≤ 13 + 7
2 </span>≤ 5y <span>≤ 20
2/5 </span>≤ y <span>≤ 20/5
0.4 </span>≤ y <span>≤ 4

Hope this helps :)</span>

<span>The <u>correct answer</u> is:

from y=2/5 to y=4.

Explanation<span>:

To solve this, we set the binomial equal to each end of the interval and solve for y.

First the lower end:
-5=5y-7

Add 7 to both sides:
-5+7=5y-7+7
2=5y.

Divide both sides by 5:
2/5 = 5y/5
2/5 = y.

This gives us the lowest value of y that puts the binomial in this interval.

Now we follow the same process for the upper end of the interval:
13=5y-7

Add 7 to both sides:
13+7=5y-7+7
20=5y.

Divide both sides by 5:
20/5=5y/5
4=y.

This means that the highest value of y that will put the binomial in this interval is 4.</span></span>

Answer:

Step-by-step explanation:

10+18+25+27+35+50=165

n=6

mean =165/6=27.5

x   x- mean    (x-mean)²

10     -17.5          306.25

18      -9.5            90.25

25     -2.5              6.25

27     -0.5              0.25

35      7.5            56.25

50   22.5          506.25

      _____      ________

sum     0             965.5

       _____     _________

standard deviation

=\sqrt{\frac{sum}{n-1} } \\=\sqrt{\frac{965.5}{5} } \\=\sqrt{193.1} \\\approx 13.896

10 POINTS PLEASE HELP
Llana [10]

Answer:

A company sells tents in two styles, shown below.

The sides and floor of each tent made of nylon.

For tunnel tent:

In a composite figure of tunnel tent :

There are two semi circle, half cylindrical shape and its base is made of Square.

Area of semi-circle is given by:

where r is the radius the circle.

Here, Diameter(d) = 8 feet

We know that: Diameter(d) = 2 r

then;

8 = 2r

⇒ r= 4 ft.

Area of square =

then;

Area of square =  square ft

Lateral surface area of cylinder =  where r is the radius and h is the height

Here, h = 8 ft

Lateral surface area of half cylinder =  square ft

Total Surface area of tunnel tent(S)=2(Area of semi-circle)+(Lateral surface area of half cylindrical)+(Area of square)

Substitute the given values we have;

square ft.

For Pup tent:

Each side of tent = 8 ft

In a figure of Pup tent:

There are 3 square shape and two triangle.

Area of square =

then;

Area of square =  square ft

Area of a triangle is given by:

Each side of a triangle is same.

This is an equilateral triangle, and its height is given by:

then;

Area of triangle = square ft.

Substitute the given values we have;

Total surface area of Pup tent(S')

=  square ft.

⇒S' > S

therefore, the tunnel tent require less nylon to manufacture.
