Answer:

66 ft³

Step-by-step explanation:

The figure can be divided into a cuboid and a triangular prism.

Volume of the cuboid = l × w × h

Where l = 6ft, w = 3 ft and h = 2 ft

Volume = 6 × 3 × 2 = 36 ft³

Volume of  the triangular prism = Cross sectional area × Width

Where Cross sectional area = 0.5 × 10 ft × 2 ft and Width  = 3 ft

Volume = 10 × 3 = 30 ft³

Total volume = Volume of the cuboid + Volume of the triangular prism

∴ Volume of the figure = 66 ft³

Answer:

X has an hypergeometric distribution, with parameters:

Size of the population is N = 18.

Size of the sample is n = 6.

Number of successes n is k = 8.

Step-by-step explanation:

The people are chosen without replacement, which means that the hypergeometric distribution is used.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time.

This means that [tex]N = 18, k = 8[/tex]

We consider a success being a person taking the test for the first time, because X is the number among the six who are taking the test for the first time.

Suppose that six of these individuals are randomly assigned to a particular examiner.

This means that [tex]n = 6[/tex]

a. What kind of a distribution does X have (name and values of all parameters)

X has an hypergeometric distribution, with parameters:

Size of the population is N = 18.

Size of the sample is n = 6.

Number of successes n is k = 8.

Answer:

2/3

You divide the numerator and denominator by 8

Answer: 1 + [tex]\sqrt{x} 2[/tex]

Answer:

320

Step-by-step explanation:

x = y/%

x = 208/65%

65% = 0.65

x = 208/0.65

x = 320

Answer:

4 2/7=  30/7

30/7 times 7/2= 15

Answer:

A linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we want to have a slope equal to -2, then our line will be something like:

y = -2*x + b

Now, we also want this line to pass through the point (3, -4)

This means that when x = 3, we must have y = -4

Then:

-4 = -2*(3) + b

-4 = -6 + b

-4 + 6 = b

2 = b

Then our line is:

y = -2*x + 2

Now, the second part says that:

If this line  contains the points (2,8) and (5.b), find a and b.​

This is incorrectly written because this line clearly does not contain the point (2, 8), so i guess the actual problem is something like:

If this line  contains the points (a,8) and (5.b), find a and b.​

If the line contains the point (a, 8), this means that when y = 8, we must have x = a.

Then:

8 = -2*a + 2

8 - 2 = -2*a

6 = -2*a

6/-2 = -3 = a

a = -3

Similar reasoing for the other point, if the line contains the point (5, b), this means that when x = 5, we have y = b.

Then:

b = -2*5 + 2 = -10 + 2

b = -8

Answer:

  y = (x -7)² +9

Step-by-step explanation:

The vertex form of the quadratic equation is ...

  y = a(x -h)² + k . . . . . . . . vertex (h, k); vertical scale factor 'a'

If we use a vertical scale factor of a=1, then putting the vertex (h, k) = (7, 9) into the vertex form gives ...

  y = (x -7)² +9

Answer:

y > 81

Step-by-step explanation:

82 - 28 = 54

So, 54 > 53

Answer:

Step-by-step explanation:

If you use the Puythagorean Theorem, you know that 3^2+3.75^2=X^2 (with X being the hypotenuse)

Then, you simplify and add. you should get 23.0625=X^2

After that you √ (square root) both of them and you get 4.80234318=X

Answer:

-66

Step-by-step explanation:

- 13, ____, -119

first, find the common difference:

-13 - (-119) = 106

next, divide 106 by 2: [tex]\frac{106}{2}[/tex] = 53

so, the common difference is 53.

now, subtract 53 from -13:

-13 - 53 = -66

Answer:

-66

Step-by-step explanation:

the sequence goes -13,-66,-119

just subtract with 53

(decreasing arithmetic sequence)

Answer:

Try this

Step-by-step explanation:

So what you have to do is turn 65% into a decimal. 65% as a decimal is 0.65.

Then what you want to do is divide 5.00 and 0.65 and see what you get.

Answer:

a. True, b. y = (-1/2)x + 8

Step-by-step explanation:

Because the graph is a straight line, that means that the graph is in fact proportional. For the equation, take the form y = mx+b. Plug in the slope, which is -1/2, and the y-intercept, which is 8, which would give you the equation y = (-1/2)x + 8.

Answer:

1) not proportional - not starting from origin

2) (2,8) - i did it in coordinates

Answer:

Complementary angles

Step-by-step explanation:  Two angles that = 90 degrees is the definition or complementary.  Supplementary is 180 degrees.  Vertical is just a straight angle.  The reason why it isn't a right angle is because a right angle is one individual angle not 2 or more equaling 90 degrees.
