How do I find MKL? For geometry.

The probability that the number of sales is 2 or 3 is 0.50" is TRUE.

Sales (x) --> Probability (P(x))
0 --> 0.10
1 --> 0.15
2 --> 0.20
3 --> 0.30
4 --> 0.20
5 --> 0.05

To determine if the probability of making 2 or 3 sales is 0.50, we need to add the probabilities for 2 and 3 sales:

P(2 or 3) = P(2) + P(3) = 0.20 + 0.30 = 0.50

Since the sum of the probabilities for 2 and 3 sales is 0.50, the statement "Given this distribution,

the probability that the number of sales is 2 or 3 is 0.50" is TRUE.

The total number of visitors to the zoo that day=3980.

Given:

cost of each ticket for an adult=$25

cost of each ticket for an adult=$10

Total ticket sales one day=$47,750.

⇒$25+$10=47,750

⇒25+10=47,750-----(1)

Also,

c=6a+270

6a-c=-270------(2)

multiplying eq(2) with 10 we get:

60a-10c=-2700----(3)

Adding eq(1) and eq(3) we get

25a+10c=47,750

60a-10c=-2700

--------------------------

85a=45050

--------------------

To calculate a value just divide 45050 by 85 we get

a=45050/85

a=530

Now to get the value of c substitutes a value.

c=60(530)+270

c=3450

Number of Adult visitors=530

Number of children visitors=3450

Total Number of visitors=3980.

Therefore, the total number of visitors to the zoo that day=3980.

The three conditions for a function to be continuous at a point x=a are:

a) The function is defined at x=a.

b) The limit of the function as x approaches a exists.

c) The limit of the function as x approaches a is equal to the value of the function at x=a.

The continuity of a function can be analyzed by observing its graph. However, as the graph is not provided, a specific discussion about its continuity cannot be made without further information. It is necessary to examine the behavior of the function around the point in question and determine if the three conditions for continuity are satisfied.

The function f(x) = { *** is not defined in the question. In order to discuss its continuity, the function needs to be provided or described. Without the specific form of the function, it is impossible to analyze its continuity. Different functions can exhibit different behaviors with respect to continuity, so additional information is required to determine whether or not the function is continuous at a particular point or interval.

Ramundo will get a better deal at Roller worlds.

This is a question of percentages.

Given that:-

Regular price of rollerblades at roller world = $ 94

Discount at rollerworld = 15 %

Price of rollerblades at Outdoor adventures = $ 81.50

Sales tax = 6 %

Price of rollerblades at roller world after discount = 94 - (15/100)*94 = 94 - 14.1 = $79.9

Price of rollerblades at roller world after sales tax = 79.9 + (6/100)*79.9 = 79.9 + 4.794 = $ 84.694

Price of rollerblades at outdoor adventures = $81.50

In order to determine whether f'(t), the derivative of the temperature function f(t), is positive or negative, we need more information about the specific function f(t). Without additional details or the form of the function, we cannot determine the sign of the derivative.

The derivative f'(t) represents the rate of change of the temperature with respect to time. If f'(t) is positive, it means the temperature is increasing over time. If f'(t) is negative, it means the temperature is decreasing over time. However, without knowing the specific form or characteristics of the function f(t) that describes the temperature, we cannot determine the sign of the derivative. The sign of the derivative depends on the behavior of the function, such as whether it is increasing or decreasing, concave up or concave down, or has any specific patterns or constraints. To determine whether f'(t) is positive or negative, we would need additional information about the function, such as its formula, behavior, or constraints.

(a) The numerical expression 13.52-7.8 = 5.72 represents the position of the fish relative to sea level after it rises 7.8 feet  , and

(b) After rising 7.8 feet , the position of the fish will be 5.72 feet below the sea level .

In the question ,

it is given that

depth at which fish swims below the sea level = 13.52 feet

height that fish rises = 7.8 feet

Part(a)

Since the fish has risen 7.8 feet ,

hence 7.8 feet will be subtracted from the original depth ,

the equation becomes 13.52 - 7.8 = 5.72  .

Part(b)

The position of fish after it rises 7.8 feet is calculated using

= 13.52 - 7.8

Subtracting 7.8 from 13.52 we get

= 5.72

Therefore , (a) the numerical expression 13.52-7.8 = 5.72 represents the position of the fish relative to sea level after it rises 7.8 feet  , and

(b) After rising 7.8 feet , the position of the fish will be 5.72 feet below the sea level .

The given expression of trigonometry is equivalent to cos(2θ).

trigonometry capability, in math, one of six capabilities (sine [sin], cosine [cos], digression [tan], cotangent [cot], secant [sec], and co-secant [csc]) that address proportions of sides of right triangles. These six geometrical capabilities comparable to a right triangle.

We have,

1 - tan^2(θ)/1 +  tan^2(θ)

Use 1 + tan^2(θ) = sec^2(θ)

1 - tan^2(θ)/ sec^2(θ)

1/ sec^2(θ) - tan^2(θ)/sec^2(θ)

Use tan(θ) = sin(θ)/cos(θ)

cos^2(θ) - sin^2(θ)×cos^2(θ)/cos^2(θ)

cos^2(θ) - sin^2(θ)

Using sin^(θ) + cos^2(θ) = 1

cos^2(θ) - (1 - cos^2(θ))

2cos^2(θ) - 1

Here we have 2cos^2(θ) - 1 = cos(2θ)

Then, simplification of given expression is cos(2θ).

Answer:

  (c) It has exactly four faces that are triangles

  (d) It has 4 vertices

  (f) It has 6 edges

Step-by-step explanation:

You want to identify 3 true statements about a triangular pyramid.

An image of a triangular pyramid is attached.

The base is one triangular face. Each of its three edges is the base of a lateral triangular face, so there are a total of 1+3 = 4 triangular faces.

The base triangle has 3 vertices. The lateral triangular faces meet at another vertex, for a total of 3+1 = 4 vertices.

The base triangle has 3 edges. Each of the 3 base vertices joins the fourth vertex with an additional edge, for a total of 3+3 = 6 edges.

A triangular pyramid has 4 faces, 4 vertices and 6 edges.

Answer:

We have the system:

x ≤ 7

x ≥ a

Now we want to find the possible values of a such that the system has, at least, one solution.

First, we should look at the value of a where the system has only one solution:

We can write the 2 sets as:

a ≤ x

x ≥ 7

So, writing both together:

a ≤ x ≤ 7

if a is larger than 7, we do not have solutions.

then a = 7 gives:

7 ≤ x ≤ 7

Here the only solution is 7.

Now, if a is smaller than 7, for example 5, we have:

5 ≤ x ≤ 7

Now x can take different values, so we have a lot of solutions.

Then the restrictions for a, such that the system has at least one solution, is:

a ≤ 7.

The height of a cone with a diameter of 12m whose volume is 226m³ is 6 meters.

The formula for the volume of a cone is

V = (1/3) * π * r^2 * h

where V is the volume, r is the radius, h is the height, and π is approximately equal to 3.14.

We know the diameter of the cone is 12m, which means the radius is 6m.

We also know that the volume of the cone is 226m^3.

Substituting these values into the formula, we get:

226 = (1/3) * π * 6^2 * h

Simplifying:

226 = (1/3) * 3.14 * 36 * h

226 = 37.68h

h = 226/37.68

h ≈ 6

Therefore, the height of the cone is approximately 6 meters.

The latest time for pickup, found by converting the 150 minutes maximum time provided by the school, from minutes to hours is about 5:45 pm

Minutes can be converted into hours by dividing the number of minutes by 60, which is the number of minutes in an hour.

The time that school ends = 3:15 pm

The latest time for pick up after school care = 150 minutes after school ends

Therefore, the latest time for pick up after school care = 3:15 pm + 150 minutes

60 minutes = 1 hour

150 minutes = (1/60) × 150 = 2.5

The latest for pick up = 3:15 pm + 2.5 hours = 5:45 pm

Step-by-step explanation:

To determine Km from a double-reciprocal plot, you would choose option (A) which is to multiply the reciprocal of the x-axis intercept by -1.

In the double-reciprocal plot equation, the x-axis intercept is -1/Km, and the y-axis intercept is 1/Vmax. Therefore, if you take the reciprocal of the x-axis intercept, you get -Km, and multiplying it by -1 gives you Km.

This method is preferred because it is more accurate than estimating Km based on the position of the curve on the plot or by taking the x-axis intercept where V0 = 1/2 Vmax, which can be influenced by experimental error.
