About 80 necklaces have more than 28 beads. Then the correct option is C.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and the standard deviation is 4 beads.

P(x > 28) = P(x - 24 / 4 > 28 - 24 / 4)

P(x > 28) = P(x - 24 / 4 > 1)

P(x > 28) = 1 - ∅1

P(x > 28) = 1 - 0.8413

P(x > 28) = 0.1587

Multiply both sides by 500, then we have

500 P(x > 28) = 0.1587 × 500

500 P(x > 28) = 79.35

500 P(x > 28) ≈ 80

About 80 necklaces have more than 28 beads. Then the correct option is C.

Step-by-step explanation:

You want to identify the graphs that go with each of these functions, along with a particular point on the curve.

The equations are written here in standard form, factored form, and vertex form. (The "factored form" is sometimes called "intercept form.") Each of these forms can be analyzed for characteristics relevant to identifying the corresponding graph.

In general, we can readily identify the opening direction, based on the sign of the leading coefficient. Depending on the form, we can also identify zeros, the vertex, and the y-intercept.

The line of symmetry (x-coordinate of the vertex) of the equation in the form ax² +bx +c is x = -b/(2a). That is, it will be left of the y-axis when the coefficients 'a' and 'b' have the same sign.

The graph of equation A will be graph 4, the only one with its vertex left of the y-axis. The y-intercept is the constant: point S = (0, 9).

Equation B has a positive leading coefficient, so opens upward. The zeros of the factors are -3 and +9, so identify the places where the graph crosses the x-axis. Graph 3 is the only one that opens upward and has x-intercepts. Point R is (9, 0).

The vertex form of a quadratic is ...

  y = a(x -h)² +k . . . . . . . vertex (h, k); leading coefficient 'a'

Equation C has its vertex at (h, k) = (3, 9) and opens upward (a>0). Graph 1 is the only one matching those characteristics. Point P is the vertex, so point P is (3, 9).

Equation D is the same as equation B, but with a negative leading coefficient. That is, it opens downward and crosses the x-axis in two places, at x = -3 and x = 9. Graph 2 is matches this description. The left zero is point Q, (-3, 0).

Step-by-step explanation:

% in calculations are always represented as hundredths, as 100% represents the whole, and n% = n/100 of the whole.

x = pounds of 35% alloy.

y = pounds of 52% alloy.

x + y = 45

0.35x + 0.52y = 0.47(x + y)

from the first equation we get e.g.

x = 45 - y

now we use this in the second equation :

0.35(45 - y) + 0.52y = 0.47((45 - y) + y)

15.75 - 0.35y + 0.52y = 0.47(45 - y + y)

15.75 + 0.17y = 0.47×45 = 21.15

0.17y = 5.4

y = 5.4/0.17 = 31.76470588... pound

x = 45 - y = 13.23529412... pound

Answer:

Step-by-step explanation:

The form of the equation you are given is called "point-slope" form. The "slope" in this case is the per-hour fee. The point is (9 h, $195). Point-slope form generally looks like this:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

Here, you have m=15, (h, k) = (9, 195), so the equation looks like ...

  y -195 = 15(x -9)

__

The "one-time fee" is the cost when hours are zero.

  y -195 = 15(0 -9)

  y = 195 -9(15) = 60 . . . . add 195 to both sides, and evaluate

The one-time fee is $60.

Create a list of the names in the order they're given and order them through the information provided.

The equation you used is correct, but the differential equation does not include the growth rate. The growth rate is proportional to the current population, so the differential equation should look like this:  dp/dt = kP - 20,000t

dp/dt = kP - 20,000t  , Where k is the growth rate. To solve this equation, we can use the separation of variables: dp/P = kdt - 20,000tdt

Integrating both sides, we get:

ln|P| = kt - 20,000t^2/2 + C, Where C is the integration constant. To find C, we can use the initial population of 200,000:

ln|200,000| = -0.099t - 20,000t^2/2 + C

=>C = ln|200,000| + 0.099t + 20,000t^2/2  .Therefore, the population of mosquitoes at any given time t is:

P = 200,000e^(-0.099t - 20,000t^2/2 + ln|200,000| + 0.099t + 20,000t^2/2)  = 200,000e^(ln|200,000|)  = 200,000

Answer:

Option (C)

Step-by-step explanation:

AB and BC are perpendicular to each other at point B.

Ordered pairs representing points A and B are (-3, -1) and (4, 4)

Slope of AB, \((m_1) = \frac{y_2-y_1}{x_2-x_1}\)

                             \(=\frac{(4+1)}{4+3}\)

                             \(=\frac{5}{7}\)

Let the slope of perpendicular line BC = \(m_2\)

By the property of perpendicular lines,

\(m_1\times m_2=-1\)

\(\frac{5}{7}\times m_2=-1\)

\(m_2=-\frac{7}{5}\)

Equation of line BC → y - y' = m₂(x - x')

Let y be 115.5

Now

Answer:

A)  c = 16.5h

B)   $74.25

C)  7 hours

Step-by-step explanation:

Bazinga charges $16.50 per hour to dog sit.

Therefore, to calculate the total charge, multiply the number of hours by the charge per hour:

\(\large \begin{array}{| c | c |}\cline{1-2} \sf number\:of\:hours & \sf charge\:in\:dollars\\\cline{1-2} 1 & 16.50 \\\cline{1-2} 3 & 49.50 \\\cline{1-2} 6 & 99.00 \\\cline{1-2} 8 & 132.00 \\\cline{1-2}\end{array}\)

As explained above, to calculate the total charge, multiply the number of hours worked by the charge per hour of $16.50

⇒ c = 16.5h

where:

To calculate how much Bazinga will earn if they dog sit for 4.5 hours, substitute h = 4.5 into the equation and solve for c:

⇒ c = 16.5h

⇒ c = 16.5(4.5)

⇒ c = $74.25

To calculate how long it will take Bazinga to earn $115.50, substitute c = 115.5 into the equation and solve for h:

⇒ c = 16.5h

⇒ 115.5 = 16.5h

⇒ h = 115.5 ÷ 16.5

⇒ h = 7 hours

Prices of two ratios in the ratio is 4 : 1.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related.

For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole.

For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books.

Let us assume price of radios are x and y

According to the question

\(\frac{x + 20}{y+20} =\frac{5}{2}\\2x+40=5y+100\\2x-5y=60\)-------------------------- eq(1)

and

\(\frac{x-5}{y-5} =\frac{5}{1}\\5y-x = 20\)

5y-x = 20

multiplying this equation by 2

we get

10y-2x = 40 ------------------ eq(2)

An example of a one-to-one function that is an isomorphism between sets P and Q is the function f: P -> Q defined as f(x) = 2x, where P and Q are the sets of integers.

This function is one-to-one because for every element x in P, there is a unique element 2x in Q. It is onto because every element y in Q has a preimage x in P such that f(x) = y (e.g., y/2 = x).

Furthermore, this function preserves the group structure between P and Q, as it satisfies the properties of an isomorphism. In this case, the group structure is addition, and the function f preserves addition: f(x + y) = 2(x + y) = 2x + 2y = f(x) + f(y) for all x, y in P.

Therefore, the function f: P -> Q defined as f(x) = 2x is an example of a one-to-one function that is an isomorphism between sets P and Q.

2 · (2 · x + 30) = x + 27

4 · x + 60 = x + 27

3 · x = - 33

x = - 11

Case 2

(2 · x + 31) / (x + 29) = 1 / 2

2 · (2 · x + 31) = x + 29

4 · x + 62 = x + 29

3 · x = - 33

x = - 11

Case 3

(2 · x + 27) / (x + 24) = 1 / 2

2 · (2 · x + 27) = x + 24

4 · x + 54 = x + 24

3 · x = - 30

x = - 10

Case 4

(x + 19) / (x + 30) = 1 / 2

2 · (x + 19) = x + 30

2 · x + 38 = x + 30

x = - 8

Case 5

(x + 18) / (x + 30) = 1 / 2

\(\sf 5n - \frac{1}{2} = \frac{1}{2} \\\)

Step 2: Add \(\sf \frac{1}{2} \\\) to both sides of the equation:

\(\sf 5n = \frac{1}{2} + \frac{1}{2} \\\)

\(\sf 5n = 1 \\\)
