There are 3024 possible arrangements of 4 items selected from a total of 9 with replacement.

It is required to find the number of permutations when 4 things are selected from a total of 9 with replacement.

Use the formula for permutations with replacement, which is:

= [tex]^np_r[/tex]

Here n is the total number of items and r is the number of selections.

As per the question, n = 9 and r = 4.

So, the number of permutations is:

= ⁹p₄

= 9!/5!

= 9 x 8 x 7 x 6

= 3024

Thus, there are 3024 possible arrangements of 4 items selected from a total of 9 with replacement.

The exponential function represented by the given graph is:

y = 2(.5^x)

Here we have an exponential decay, the general form of these functions is:

y = A*(b)^x

Where A is the initial value and b is the base, and it is a decay if 0 < b < 1.

Now let's look at the y-intercept, we can see that it is y = 2, then:

2 = A*(b)^0

2 = A

The function is of the form:

y = 2*(b)^x   with 0 < b < 1.

The option that meets these conditions is the first one: y = 2(.5^x)

The width of the worktable is 32 inches, and the length of the worktable is 82 inches.

Let's assume that the width of the worktable is "w" inches.

We are given that the length is 18 inches more than twice the width, which can be expressed as:

Length = 2w + 18

The perimeter of the worktable is the sum of the lengths of all four sides.

We know that the perimeter of the worktable is 228 inches, so we can write an equation:

Perimeter = 2 × (Length + Width)

228 = 2 × (2w + 18 + w)

228 = 2 × (3w + 18)

Dividing both sides by 2:

114 = 3w + 18

Subtracting 18 from both sides:

96 = 3w

Dividing both sides by 3:

w = 32

So, the width of the worktable is 32 inches.

Now we can use this value to find the length:

Length = 2w + 18

Length = 2 × 32 + 18

Length = 82

So, the length of the worktable is 82 inches.

To ascertain the amount of water that is passing through the hourglass daily:

where:

Total water capacity: 2000 pounds

Time: 365 days

Water transpiring every day = Total water capacity / Time

To solve thhis linear programming problem, we can use the graphical method..

Graph the feasible region defined   by the constraints.....

x >= 0 and y >= 0 represent the non-negative quadrants.

x + y < = 8   represents the area below the line passing through ( 8, 0) and (0, 8).

x + y >= 2 represents the area above the line passing through (  2 , 0) and (0 , 2).

Calculate tthe objective function at each corner point....

z(0,   2  ) = 3(0) + 4(2) = 8

z (2, 0  ) = 3(2) + 4(0) = 6

z(4, 4  ) = 3(4) + 4(4) = 28

z (  8, 0) = 3(8) + 4(0) = 24

The percentage of the total that women represent, would be 60% of the total.

Given that 60 % of men is equal to 40 % of women, we have :

0. 6 M = 0. 4 W

Solving for women in terms of Men gives:

W = ( 0.6 x M) / 0.4

= 1.5 x M

We can then find the percentage of women to be:

Answer:

Put your calculator in degree mode.

sin(13°) = 500/x

x sin(13°) = 500

x = 500/sin(13°) = 2,222.7 miles

Using a trigonometric relation we can see that x =  2,222.7 ft

We can see a right triangle, there we can see that one of the angles has a measure of 13°.

The opposite cathetus has a measure of 500ft, and we want to find x, which is the hypotenuse.

Then we can use the relation:

sin(a) = (opp cathetus)/hypotenuse

Replacing what we know, we will get:

sin(13°) = 500/x

Solving that for x:

x = 500/sin(13°) = 2,222.7 ft

Answer:

  499,237 ft²

Step-by-step explanation:

You want the lateral area of a square pyramid 580 feet on a side and 318 feet tall.

To find the area of each triangular face, we must know its slant height. That can be found from the base and height of the pyramid using the Pythagorean theorem. Once we know the slant height, we can use the formula for the area of a triangle:

  A = 1/2bh

There are 4 congruent triangular faces, so the lateral area of the pyramid will be 4 times the area of one face:

  4A = 4(1/2bh) = 2bh

The slant height of a face of the pyramid is the hypotenuse of a right triangle with one leg equal to the height of the pyramid, and the other leg equal to half the length of a base edge. (This is the distance from the midpoint of the bottom edge of a face to the center of the base, under the peak of the pyramid.)

  h = √((580/2)² + 318²) ≈ 430.3766 . . . . feet

  lateral area = 2(580 ft)(430.3766 ft) ≈ 499237 ft²

The surface area of the glass is about 499237 square feet.

Answer:

Step-by-step explanation:

The function f(x) = a * b^x represents exponential growth or decay. The value of a represents the starting value or y-intercept, while the value of b represents the growth or decay factor. If b is greater than 1, the function represents exponential growth, while if b is between 0 and 1, the function represents exponential decay.

To determine the values of a and b from a graph, we need to look for specific features. The y-intercept represents the value of a, so we can read it directly from the graph. The growth or decay factor b can be found by examining the slope of the graph. If the graph is increasing, then b is greater than 1, and if it is decreasing, then b is between 0 and 1.

Answer:

mean=5

Step-by-step explanation:

To find the mean of a set of data, we add up all the values in the set and then divide by the number of values.

Adding up the values in the set, we get:

3 + 5 + 4 + 4 + 5 + 7 + 7 = 35

There are 7 values in the set, so we divide the sum by 7 to get the mean:

mean = sum of values / number of values

mean = 35 / 7

mean = 5
