Trudy has been training for an upcoming marathon. She has kept track of how many miles she runs every day for the past two weeks:

12, 15, 7, 14, 12, 3, 16, 15, 19, 20, 12, 9, 18, and 21.

a. Calculate the mean and median for this data.

Mean:
Median

b. Calculate the Quartile 1 (Q1)
Quartile 2 (Q2)

d. What is the IQR (Interquartile Range):

Answer:

13

Step-by-step explanation:

Since Seth pays $0.50 for each check he writes, he would write (let x be how many checks Seth wrote) "x" checks for $6.50. That means;

1 = 0.50

x = 6.50

Now let us set up a fraction:

[tex]\frac{0.5}{1}=\frac{6.5}{x}[/tex]

Step 1: Cross multiply

[tex]0.5x=1\cdot \:6.5[/tex]

[tex]0.5x=6.5[/tex]

Step 2: Divide both sides by [tex]0.5[/tex]

[tex]\frac{0.5x}{0.5}=\frac{6.5}{0.5}[/tex]

Simplify

[tex]x=13[/tex]

Therefore, Seth will write 13 checks for $6.50

Answer:

9.81 x 100,000

Step-by-step explanation:

Answer:

9.81*10^5

Step-by-step explanation:

Move the decimal point to the right of the first digit of the number. It should be a decimal number between 1 and 10. Write that down.

Then count the number of places you need to move the decimal point from that place to the right, and that's how many times 10 needs to be squared.

Answer:

E

Step-by-step explanation:

Cos=Adjacent/hypotenuse

Cos30=rad3/2

The cosine function for Ф = 30 is equivalent to :

cos(30) =√3/2.

There are six major trigonometric functions as -

We can write the relation between them as -

Also the following trigonometry relations hold true -

sin²Ф + cos²Ф = 1

1 + tan²Ф = sec²Ф

1 + cot²Ф = cosec²Ф

Given is a right angled triangle as shown in the image having 60 - 90 - 30 orientation and the measured sides as shown in the image.

We can write the cosine function as -

cosФ = Base/Hypotenuse

cos(30) = √3/2

So, we can conclude that the cosine function for Ф = 30 is equivalent to :

cos(30) =√3/2

Therefore, the cosine function for Ф = 30 is equivalent to :

cos(30) =√3/2.

Given:

The given point is (4,12).

To find:

The equation that would NOT contain the point (4,12).

Solution:

We need to check each equation for the point (4,12).

In option A, the given equation is:

[tex]y=-2x+20[/tex]

Putting [tex]x=4[/tex], we get

[tex]y=-2(4)+20[/tex]

[tex]y=-8+20[/tex]

[tex]y=12[/tex]

This equation contains the point (4,12).

In option B, the given equation is:

[tex]y=\dfrac{1}{2}x+8[/tex]

Putting [tex]x=4[/tex], we get

[tex]y=\dfrac{1}{2}(4)+8[/tex]

[tex]y=2+8[/tex]

[tex]y=10[/tex]

This equation does not contain the point (4,12).

In option C, the given equation is:

[tex]y=-\dfrac{1}{2}x+14[/tex]

Putting [tex]x=4[/tex], we get

[tex]y=-\dfrac{1}{2}(4)+14[/tex]

[tex]y=-2+14[/tex]

[tex]y=12[/tex]

This equation contains the point (4,12).

In option D, the given equation is:

[tex]y=\dfrac{3}{4}x+9[/tex]

Putting [tex]x=4[/tex], we get

[tex]y=\dfrac{3}{4}(4)+9[/tex]

[tex]y=3+9[/tex]

[tex]y=12[/tex]

This equation contains the point (4,12).

Only the equation in option B does NOT contain the point (4,12). Therefore, the correct option is B.

Answer:

Center: (4,-2)

Radius: 2√3 units

Step-by-step explanation:

We wish to find the center and radius of the equation x²+y²-8x+2y=-8

Step 1: Complete the square for both variables:

x²+y²-8x+2y=-8

x²-8x+y²+2y=-8 (Rearrange)

x²-8x+16+y²+2y+4=-8+16+4 (Add to both sides)

(x-4)²+(y+2)²=12 (Reduce trinomials)

Step 2: Interpret the center and radius of the circle:

The equation of a circle is (x-h)²+(y-k)²=r² where (h,k) is the center of the circle and r is the radius of the circle. Since (h,k) translates to (4,-2), this means the center of the circle is (4,-2). Since r²=12, then r=√12=2√3 units

Answer:

A. 44/625

Step-by-step explanation:

There are 25 marbles total. To first calculate the probability of picking a yellow marble first can be represented as 11/25, the probability of picking blue is 4/25. We multiply these to figure out the probability of finding a yellow marble and then a blue one.

11/25 x 4/25 = 44/625

Answer:

-6

Step-by-step explanation:

- 28 – 6b= 8

step 1 add 28 to each side

-28 + 28 cancels out

28 + 8 = 36

we now have -6b = 36

step 2 divide each side by -6

-6b / -6 = b

36 / -6 = -6

we're left with b = -6

Hi there!

Answer:

14

Step-by-step explanation:

The numbers you are describing can end in 5. But there are others as well. They are  t = 10 + 20*n where n goes from 0 to 4. So if n is 4 that means that t = 4*20 + 10 = 80 + 10 = 90.
