Of the 25 students who take a standardized test, the minimum score is 98 and the maximum score is 312. The mean score is 216. Standard deviation is 52. What is the number of standard deviations that includes all the data values?

The domain of the function represented by the graph is x ≥ 0

The function is represented by the graph of the function

From the given graph, we have the following observations

This means that the function has a domain of all set of real values greater than or equal to 0

This is represented as

x ≥ 0

So, the domain is x ≥ 0

Answer:

[tex]m\angle Y=30^{\circ}[/tex]

Step-by-step explanation:

In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.

Therefore, we have:

[tex]\cos Y=\frac{42\sqrt{3}}{84},\\Y=\arccos(\frac{42\sqrt{3}}{84})=\boxed{30^{\circ}}[/tex]

Answer: 20,403.72ft3

Step-by-step explanation:Volume formula for cylinder is   = 2h

V=Volume

=pi=3.14

r=radius

h=height

Step 1: find the radius.

Diameter=38

so divide 38 by 2

=19

Step 2: Plug in and solve for Volume.

V=3.14x19^2x18

= V=1133.54x18

= V=20,403.72

Answer:

Step-by-step explanation:

to convert the fraction to percentage just multilpy the fraction will 100%

1/5

1/5*100%

100%/5

20%

12/100

3/25

0.12

or in division decimal point goes to the right side

12 can also be written as 12.00 so move the decimal point 2 unit right which becomes .12 .In this case we should move 2 units right because there it is divides by hundred and there are 2 zeros in number hundred.Remember how many units to move right depends upon the number it is divided with.

1/5 is equal to 20% when expressed as a percentage and 12/100 is equal to 0.12 when expressed as a decimal.

To convert 1/5 to a percentage, we can multiply it by 100.

(1/5) * 100 = 20%

Therefore, 1/5 is equal to 20% when expressed as a percentage.

To convert 12/100 to a decimal, we divide the numerator (12) by the denominator (100).

12 ÷ 100 = 0.12

Therefore, 12/100 is equal to 0.12 when expressed as a decimal.

When converting a fraction to a percentage, we multiply the fraction by 100. In this case, 1/5 is equivalent to 0.2 as a decimal. Multiplying it by 100 gives us 20%, expressing the fraction as a percentage.

When converting a fraction to a decimal, we divide the numerator by the denominator. In the case of 12/100, dividing 12 by 100 gives us the decimal representation of 0.12.

So V=12x8x9

V=864 Cubic feet

Answer:

x = 60°

Step-by-step explanation:

∠ CGE = ∠ FGD = 30° ( vertical angles )

∠ CGB = 90° , then

x + 30° = 90° ( subtract 30° from both sides )

x = 60°

Answer:

[tex]x=2\sqrt3\ km[/tex]

Step-by-step explanation:

Given that,

The base of a triangle = 2 km

The perpendicular height of the triangle = [tex]2\sqrt{2} \ km[/tex]

We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :

[tex]x=\sqrt{(2\sqrt{2})^2+2^2 } \\\\=2\sqrt{2+1 } \\\\=2\sqrt3\ km[/tex]

So, the value of x is equal to [tex]2\sqrt3\ km[/tex].

Answer:

[tex]A=2x^2+8x+6\ yards^2[/tex]

Step-by-step explanation:

Step 1, finding the dimensions:

The width of Stacy's room is x, so the length must be 2x. (Her length of the room is two times the width.)

Her sister's room is 2 yards longer and 3 yards wider than Stacy's room. We have:

Length: [tex]2x+2[/tex]

Width: [tex]x+3[/tex]

Great! Let's find the area now.

Step 2, finding the area:

The area of a rectangle is [tex]A=l*w[/tex], where l represents the length of the rectangle, and w represents the width of the rectangle. We already know both, so we can plug it in the equation:

[tex]A=(2x+2)(x+3)[/tex]

We can expand and simplify:

[tex]A=2x^2+2x+6x+6\\A=2x^2+8x+6\ yards^2[/tex]

Answer:

The answer would be the third one, 3(x -2)=18

Answer:

75

Step-by-step explanation:

f(1) = 7

f(n) = 3f(n-1) + 3

So what you are trying to do here is find the recursive value (that's what it is called) for f(n). Computers love this sort of thing, but we humans have to do it slowly and carefully.

So let's try f(2)

That means that f(2) = 3*f(n-1) + 3

but if f(2) is used it means that you have to know f(2-1) which is just f(1) and we know that.

so f(2) = 3*f(1)+3

f(2) = 3*7 + 3

f(2) = 21 + 3

f(2) = 24

Now do it again. We now know F(2), so we should be able to find f(3)

f(3) = 3*f(3 - 1) + 3  

f(3) = 3*f(2) + 3      We know that f(2) = 24

f(3) = 3* 24 + 3

f(3) = 72 + 3

f(3) = 75

Answer:

When dropped from 450 feet, the crate and medical supplies will not survive the impact

Step-by-step explanation:

The impact that the crate can withstand when dropped = 165 ft,/sec

The function for the height of the crate at 450 ft. = 450 - 16·t²

The time the crate will land after drop = 5.3 sec

Therefore, we have;

Velocity, V(t) = d(h)/dt

∴ v(t) = d(450 - 16·t²)/dt = -32·t

Given that the time the cate lands after drop, t = 5.3 seconds, we have;

The velocity at 5.3 seconds after drop, v(5.3) = -32 × 5.3 = -169.6

The velocity at 5.3 seconds after drop, v(5.3) = 169.6 ft./sec. (downwards)

Therefore, given that the velocity of the crate at 5.3 seconds (169.6 ft./sec.) is higher than the velocity at which the crate can withstand an impact (165 ft./sec.) the crate and medical supplies will not survive.
