Answer:

Step-by-step explanation:

First, let us substitute x and y values: -7 = -2(-5) + 4

Next, let us simplify using the substitution property of equality: 14 = -7 (SEE BELOW MORE INFO).

Now, this does not make sense yet because 14 cannot possibly equal -7. Therefore, we must add a b value, therefore leading us to the equation:

14 + b = -7

by simplifying, we can conclude that b = -21

Finally, we can plug in the b-value into our original equation:

y = -2x + 4 - 21

After simplifying, we get y = -2x - 17. When this is graphed, we can see that -2x - 17 intersects (-5, -7).

The function of the sequence -4,-6,-9,-27/2,-81/2 is f(n) = -4(3/2)^(n - 1)

from the question, we have the following parameters that can be used in our computation:

-4,-6,-9,-27/2,-81/2

The above sequence is a geometric sequence

This is because it has a common ratio calculated as

r = -6/-4

So, we have

r = 3/2

The sequence is then represented as

f(n) = ar^n-1

So, we have

f(n) = -4(3/2)^(n - 1)

Hence, the function is f(n) = -4(3/2)^(n - 1)

The equation 2 log₅ x = log₅ 4 + log₅ 9 has two solutions: x = 6.

To solve the equation 2 log₅ x = log₅ 4 + log₅ 9, we can use logarithmic properties to simplify and find the value of x.

Using the properties of logarithms, we can rewrite the equation as follows:

2 log₅ x = log₅ (4 * 9)

Next, we simplify the right side:

2 log₅ x = log₅ (36)

Now, we can use the property of logarithms that states logₐ b = c is equivalent to aᶜ = b. Applying this property, we have:

x² = 36

Taking the square root of both sides, we get:

x =  √36

Since the square root of 36 can be either positive or negative, we have two possible solutions:

x = 6

It's important to note that when working with logarithmic equations, we must always check if the obtained solutions satisfy the domain restrictions of the original equation. In this case, since the logarithm has a base of 5, the solution x = 6.

Answer:

23.42

Step-by-step explanation:

If something is decreasing by 7% we can mulitply it by (1-.07) or .93

so our formula is

100(.93)²⁰= 23.42388737

which rounds to 23.42

Using the exponential decline function ; the cost of the item after 20 years would be $23.42

Recall :

Substitute the values into the equation :

\( y = 100(1 - 0.07)^{20} \)

\( y = 100(0.93)^{20} \)

\( y = 100(0.23423887366)\)

y = $23.42

Therefore, the cost of the item after 20 years is $23.42

The equation of the largest sphere with center that is contained completely in the first octant is (x-1/2)² + (y-1/2)² + (z-1/2)² = 1/4.

First, let's define what the first octant is. The first octant is the space that is defined by positive x, y, and z coordinates. This means that all points in the first octant have a positive x-coordinate, a positive y-coordinate, and a positive z-coordinate.

To find the center of the sphere, we need to consider that it is contained completely within the first octant. This means that the center of the sphere must have coordinates that are less than the maximum values of x, y, and z coordinates in the octant.

Let's call the center of the sphere (a, b, c) and the radius r. Since the sphere is contained in the first octant, we know that a, b, and c are positive values. We also know that the sphere is the largest possible, so the radius r is equal to the minimum value of a, b, and c.

So, we can say that the equation of the sphere is

=> (x-a)² + (y-b)² + (z-c)² = r².

We need to find the values of a, b, c, and r such that the sphere is the largest possible and is completely contained within the first octant.

To find these values, we need to consider that the maximum values of x, y, and z in the first octant are all equal to 1 (since all coordinates are positive). So, we can set a, b, and c to be less than or equal to 1, and r to be the minimum value of a, b, and c.

After some calculations, we can see that the maximum value of r is 1/2 (when a = b = c = 1/2), and the center of the sphere is (1/2, 1/2, 1/2). Therefore, the equation of the largest sphere that is completely contained in the first octant is:

(x-1/2)² + (y-1/2)² + (z-1/2)² = 1/4.

Answer:

(11π/9 )ft/s

Step by step Explanation

Let us denote the height as h ft

But we were told that The diameter of the base of the cone is approximately three times the altitude, then

Let us denote the diameter = 3h ft, and the radius is 3h/2

The volume of the cone is

V = (1/3)π r^2 h

Then if we substitute the values we have

= (1/3)π (9h^2/4)(h) = (3/4)π h^3

dV/dt = (9/4)π h^2 dh/dt

We were given as 22feet and rate of 8 cubic feet per minute

h = 22

dV/dt = 8

8= (9/4)π (22) dh/dt

= 11π/9ft/s

Therefore, the rate is the height of the pile changing when the pile is 22 feet is

11π/9ft/s

The value of x, considering the vertical angles in this problem, is given as follows:

x = 11.

Vertical angles are angles that are opposite by the same vertex on crossing segments, hence they share a common vertex, thus being congruent, meaning that they end up having the same angle measure.

The vertical angles for this problem are given as follows:

As the vertical angles are congruent, the value of x is obtained as follows:

2x - 4 = x + 7

x = 11.

Answer:

So for the head and tails one it is 1/1 chance of getting a head and for the dice on it is 1/21 that's the porbability hopes this helps :)

Step-by-step explanation:

Probability of getting a head on the coin and a 4 on the die​ is 0.083.

Probability defines the likelihood of occurrence of an event. Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability(Event) = Favorable Outcomes/Total Outcomes

According to the question

A coin is flipped and a die is rolled

Probability of getting a head on the coin and a 4 on the die​:

Total Number of favorable outcomes(coin is flipped) = {H, T}  = 2

Number of favorable outcomes (head) = 1

Total Number of favorable outcomes(die is rolled) = {1, 2, 3, 4, 5, 6}  = 6

Number of favorable outcomes (4 on the die) = 1

P(head) = \(\frac{1}{2}\)

P(4) = \(\frac{1}{6}\)

P(head and 4) = \(\frac{1}{2}\). \(\frac{1}{6}\)

= \(\frac{1}{12}\)

= 0.083

Hence, Probability of getting a head on the coin and a 4 on the die​ is 0.083.

The percentage probability that a random selected consumer will recognize Costco will be 96.3%.

Given, the total number of consumers who recognized the brand was 1036. And the total number of consumers who didn't recognize the brand was 40. Therefore, the total number of our sample will be :

⇒1036 + 40

⇒1076

Now, we know that probability(P) of an event = f/n

where f is the number of favorable outcomes and n is the number of total outcomes. Here, number of favorable outcome is 1036.

Now, the probability that a random selected consumer will recognize the brand will be:

⇒ P = f/n

⇒ P = 1036/1076

⇒P = 0.96282

Therefore, the percentage of probability of consumers recognizing the brand rounded to one decimal place accuracy will be 96.3%.

Answer:

Explained below.

Step-by-step explanation:

A parameter is a valuable element of statistical analysis. It denotes the characteristics that are used to define a given population. It is used to define a particular attribute of the population. For instance, population mean, population standard deviation, population proportion and so on.

While making a statistical conclusion about the population under study, the parameter value is unknown. This is because it would not be possible to gather data from every single member of the population. So a sample is selected from the population to derive a conclusion about the parameter.

A statistic is the value of the characteristics that are computed using this sample. For instance, sample mean, sample standard deviation, sample proportion and so on.
