Answer:

5/136

Probability is the chance of an event happening.

Probability = (Favorable outcome)/(total outcome)

P(r and n) = 2/17 × 5/16

=(2 × 5)/(17 × 16)

= 10/272

= 5/136

Answer:

5/136, or about 3.68%

Step-by-step explanation:

There are 17 total books on the bookshelf and only two of them are reference books, so the probability that you randomly grab a reference book is 2 out of 17, or 2/17.

Now that you took out a reference book (and did not put it back) there are 16 books on the bookshelf and you know five of them are nonfiction. That means the probability of getting a nonfiction book on your second grab is 5/16.

To find the probability that both of these events happen, you multiply the two fractions together.

2/17 x 5/16 = 10/272, which can reduce to 5/136, or about 3.68%

Answer:

[tex] P_{44} = 29.9 [/tex]

Step-by-step Explanation:

The 44th percentile, [tex] P_{44} [/tex], of the given data can be calculated using the kth formula for percentile given as:

[tex] i = \frac{k}{100}(n + 1) [/tex]

where,

i = the ranking or the position of the percentile = ?

k = the percentile = 44

n = total number of the given data values = 23

Plug in the values into the formula to find "i"

[tex] i = \frac{44}{100}(23 + 1) [/tex]

[tex] i = \frac{44}{100}(24) [/tex]

[tex] i = \frac{1,056}{100} [/tex]

[tex] i = 10.56 [/tex]

Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.

Thus,

[tex] i_{down} = 10.56 = 10 [/tex]

[tex] i_{up} = 10.56 = 11 [/tex]

The data occupying the 10th position on the data set = 28.7

11th = 31.1

[tex] P_{44} = \frac{28.7 + 31.1}{2} = \frac{59.8}{2} [/tex]

[tex] P_{44} = 29.9 [/tex]

Answer:

-1,325 ft below sea level

Step-by-step explanation:

0(surface level) - 1,500 = -1,500

-1,500 + 525 = -975

-975 - 350 = -1,325

Answer:

they are currently at -1325 ft.

Step-by-step explanation:

first yo go up or in other words you subtract 525 to 1500 which gives you 973 then they descend 350 so they are going back down so you add 350 onto 975

Step-by-step explanation:

3/4 is the scale factor for a circle with radius 9 in to a circle with diameter 24 in.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The scale factor of a circle to another is the ratio of their radii

Radius of the first circle = 9 in

Diameter of the second circle = 24 in

Radius = Diameter / 2

Radius of the second circle = 24 / 2

Radius of the second circle = 12 in

Scale factor = (Radius of the first circle) / (Radius of the second circle)

Scale factor = 9/12

Scale factor = 3/4

Hence, 3/4 is the scale factor for a circle with radius 9 in to a circle with diameter 24 in.

Answer:

(-1, -4.8)

Step-by-step Explanation:

Let the point be P, which is 3/10 of the way from A to B. This means, it divides P into AP and PB in the ratio, 3:10 = AP/PB = 3/10.

Apply the formula for internal division to find the coordinates which is given as:

[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]

[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]

Where,

[tex] A(-4, -8) = (x_1, y_1) [/tex]

[tex] B(9, 6) = (x_2, y_2) [/tex]

[tex] m = 3, n = 10 [/tex]

Plug in the necessary values to find x and y coordinates for point P

[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]

[tex] x = \frac{3(9) + 10(-4)}{3 + 10} [/tex]

[tex] x = \frac{27 - 40}{13} [/tex]

[tex] x = \frac{-13}{13} [/tex]

[tex] x = -1 [/tex]

[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]

[tex] y = \frac{3(6) + 10(-8)}{3 + 10} [/tex]

[tex] y = \frac{18 - 80}{13} [/tex]

[tex] y = \frac{-62}{13} [/tex]

[tex] y = \frac{-62}{13} [/tex]

[tex] y = -4.8 [/tex]

The coordinates of the point 3/10 of the way from A to B are (-1, -4.8)

Answer:

  5%

Step-by-step explanation:

Assuming the measurement is rounded to the nearest pound, there is the potential for the reported value to differ by 1/2 pound from the measured value. The precision of the measurement is thus ...

  (0.5 lb)/(10.0 lb) = 5/100 = 5%

Unless we know the cat's actual weight, we cannot determine the error in the measurement. If the cat actually weighs 10 pounds, the error is 0%.

Answer: Roughly 111.97

Step-by-step explanation:

1. 39 divided by 3 is 13.  

2. 4367 divided by 3 is not evenly distributed. Rounding, it would work out to be roughly 1455.66 

3. 1455.66 divided by 13 is roughly 111.97 (Again, this does not distribute evenly)

4. To check your work, multiply 111.97 times 13 and you should get somewhere around 1455.66 which is (4367 divided by 3).

Answer:

You would have to break the polynomial down into smaller binomials or monomials. Take x^2-6x-9 for instance. It would break down into (x+3)(x-3) through the a^2+2ab+b^2 formula. After that set the two nomials equal to zero and solve for x. After that, you would plug back in x to see whatever x works. You may more than two nomials after breaking it apart so keep that in mind.

Answer:

7.96 s

Step-by-step explanation:

Given the following :

h = 3t³

After t seconds, that is, t = 2

h = 3(2)³ = 3 × 8 = 24 m

Rate of change, Velocity = dh/dt

dh/dt = 3*3t^(3 - 1) = 3*3t² = 9t²

At t = 2 s ; initial velocity = 9(2)² = 9 × 4 = 36 m/s

From the 3rd equation of motion:

v² = u² + 2gh

Where g = acceleration due to gravity 9.8m/s

upward motion, g = - ve

Displacement = - 24

v² = 36² + 2(-9.8)(-24)

v² = 1296 + 470.4

v² = 1766.4

v = sqrt(1766.4)

= 42.03 m/s

Since final velocity is in downward direction : take it as negative.

Recall, :

Velocity = Displacement / time

Displacement = Velocity × time

Average Velocity = (Initial + final velocity) / 2

Displacement = - 24 m

-24 = [(36 + (-42.03)) /2] × t

-48 = - 6.03t

t = 48 / 6.03

t = 7.96s

Answer:

1722/31 or 55.55

Step-by-step explanation:

We need to write an equation.

-61( z - 56 ) = z - 28

-61z + 3416 = z - 28

-61z + 61z + 3416 = z + 61z - 28

3416 = 62z - 28

3416 + 28 = 62z - 28 + 28

3444 = 62z

3444/62 = 62z/62

3444/62 = z

Since 3444/62 isn't a whole number let's reduce

3444/2 = 1722        62/2 = 31

1722/31 is our reduced fraction

Plug it into a calculator 55.5483 but rounded to two decimal places is 55.55

Step-by-step explanation:

Step one:

Firstly we need to determine the place value of 8 in the term 78

in the term, we have 7 tens and 8 units

hence the place value of 8 in 78 is the units

Step two:

Now 1/10 of 8 is given as

0.1*8= 0.8

According to the problem statement, we are expected to find a number that has an 8 that is the same as 0.8.

Say 5.8, 6.8, 9.8

we cannot say exactly, but any number that has an 8 that is one decimal away is an equivalent

Answer:

[tex]x=\frac{-2m-10}{-2m-7}[/tex]

Step-by-step explanation:

Step 1: Write out equation

3x = (2x - 2)(m + 5)

Step 2: FOIL

3x = 2xm + 10x - 2m - 10

Step 3: Subtract 2xm on both sides

3x - 2xm = 10x - 2m - 10

Step 4: Subtract 10x on both sides

3x - 2xm - 10x = -2m - 10

Step 5: Factor out x

x(3 - 2m - 10) = -2m - 10

Step 6: Combine like terms in parenthesis

x(-2m - 7) = -2m - 10

Step 7: Divide both sides by -2m - 7

[tex]x=\frac{-2m-10}{-2m-7}[/tex]
