Total 330 four-digit numbers can be formed if the number is odd and greater than 6000.
Let's tackle the problem in three steps.
First, take into account the numbers with "6" as the first digit on the left.
Then take the first eight digits of the numbers as the leftmost digit.
Last but not least, we'll use the numbers that begin with "7" as the leftmost digit.
1. As the leftmost digit, think of the numbers that begin with "6."
Any one of the final four odd digits—1, 3, 5, or 7—is acceptable (and recommended).
You are given four options.
You can use any of the remaining 8-1-1 = 6 digits for the second and third digit.
In all, it gives you 4×6×5 = 120 choices/numbers.
2. Consider the leftmost digit as the number starting with "6."
You have 120 more options/numbers using the same logic and analysis.
Everything is going well thus far, and you only need 120 + 120 = 240 numbers.
3. Consider the numbers starting with "7" as leftmost digit.
Any of the final three odd digits—1, 3, and 5—may (and ought to) be used.
You have three options.
Any of the remaining 8-1-1 = 6 digits can be used for the second and third digit.
In all, it gives you 3×6×5 = 90 choices/numbers.
4. You have 120 + 120 + 90 = 330 numbers/options when everything is added up.
Hence we get 330 choices to create four digit numbers.

When an integer is subtracted from 8 times the next consecutive integer, the
difference is 43. Find the value of the lesser integer.
The value of the lesser integer is 5
How to determine the valueFrom the information given, we have the following deductions;
Let the lesser integer be xLet the larger integer be x + 1The expression can be represented as;
8(x + 1) - x = 43
expand the bracket, we have;
8x + 8 - x = 43
collect like terms
8x - x = 43 - 8
Subtract like terms
7x = 35
Make 'x the subject of formula
Divide both sides by 7
7x /7 = 35/7
x = 5
The lesser integer is x = 5
Thus, the value of the lesser integer is 5

Find an equation for the surface obtained by rotating the line x = 4y about the x-axis.
The equation: [tex]\frac{x^{2}}{6^{2}}={y^{2}+z^{2}[/tex], represents a circle with radius r = y = x/6, and the surface that results is a cone, as obtained with the help of surface of revolution.
What is surface of revolution?A surface created by rotating a two-dimensional curve about an axis is known as a surface of revolution. As a result, the final surface is always symmetric along the azimuth.Now,
If we consider the point (6y, y, 0) in the xy plane, it appears to be a circular path that is a cone when the curve is rotated about the x axis. The cone's equation takes the following form:
[tex]\frac{x^{2}}{c^{2}}=\frac{y^{2}}{a^{2}}+\frac{z^{2}}{b^{2}}[/tex]
Given that x = 6y, we square x = 6y to give the equation the form shown above, which results in:
x² = (6y)²
x² = 36y²
Circular paths go parallel to the y-axis, hence the equation should be circular in nature. 36z² needs to be added, so:
x² = 36y² + 36z²
=> [tex]\frac{x^{2}}{6^{2}}={y^{2}+z^{2}[/tex]
Hence, This equation represents a circle with radius r = y = x/6, and the surface that results is a cone, as obtained with the help of surface of revolution.

Suppose there is a 1.1°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 59.7°F, what will be the temperature at an altitude of 11,000 feet?
The temperature at an altitude of 11,000 feet will be 47.6°F
Calculating temperatureFrom the question, we are to calculate the temperature at an altitude of 11,000 feet
From the given information,
There is a 1.1°F drop in temperature for every thousand feet
and
The temperature on the ground is 59.7°F
Now,
We are to determine the temperature at an altitude of 11,000 feet
Since the temperature drops by 1.1°F for every thousand feet,
Then,
At an altitude of 11,000 feet, the temperature would have dropped by 1.1°F 11000/1000 times
That is, the temperature would have dropped by that magnitude 11 times
Thus,
The temperature at an altitude of 11,000 feet = 59.7°F - 11×1.1°F
The temperature at an altitude of 11,000 feet = 59.7°F - 12.1°F
The temperature at an altitude of 11,000 feet = 47.6°F
Hence, the temperature at an altitude of 11,000 feet will be 47.6°F

Answer:
y=3x-8
Step-by-step explanation:
Slope -intercept form is y=mx+b.
M represents the slope; b represents the y-intercept.
First, let's find the y-intercept.
It'll be found on the y-axis on the graph.
If you go down the y-axis, you'll see that -8 is the only point to be directly on the y-axis, so we can assume that that's the y-intercept.
Thus, the B in the equation is -8.
Now, let's find the slope.
You can think of it as rise over run. The rise is how many numbers the y-intercept either goes up or down until it can cross over to the x-axis. Crossing sideways is the run that's located on the x-axis.
You can begin from -8 and either count downward or upward.
For the sake of this graph, we'll go upward.
Do you see the dot on the coordinate (1,-5)?
Count upward and go to the side to get to that coordinate.
I count three upward and one to the right.
So as a fraction that would be 3 over 1 or 3/1.
But you can simplify that to just 3.
Thus, the M in the equation is 3.
Hence, y=3x-8.

Answer:
(a) 3.5
(b) x = 4
(c) -¹/₂
(d) -¹/₂
Step-by-step explanation:
Part (a)f(1) is the value of y when x = 1.
To find the value of y from a given value of x, find the position of x on the x-axis, then trace vertically until you meet the line. Once you meet the line, trace horizontally to the y-axis to find the corresponding value of y.
Therefore, f(1) = 3.5.
Part (b)To solve f(x) = 2, find the value of x when y = 2.
To find the value of x from a given value of y, find the position of y on the y-axis, then trace horizontally until you meet the line. Once you meet the line, trace vertically to the x-axis to find the corresponding value of x.
Therefore, the solution of f(x) = 2 is x = 4.
Part (c)The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given interval: 2 ≤ x ≤ 4
Therefore:
a = 2b = 4[tex]\implies \dfrac{f(4)-f(2)}{4-2}=\dfrac{2-3}{4-2}=-\dfrac{1}{2}[/tex]
Part (d)The average rate of change between any interval of the given function will be the same as the graph is linear. Therefore, the average rate of change from 0 to 8 is the same as the rate found in part (c): -¹/₂.
Proof
The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given interval: 0 ≤ x ≤ 8
Therefore:
a = 0b = 8[tex]\implies \dfrac{f(8)-f(0)}{8-0}=\dfrac{0-4}{8-0}=-\dfrac{4}{8}=-\dfrac{1}{2}[/tex]

The total number of times 7 can occur as the sum on rolling two cubes for 180 times is 30. It is gained by applying the knowledge of probability to the given problem.
What is probability?
Probability depicts the number of possibilities of how many times an event can occur. The probability of happening of an event invariably lies between 0 and 1. For a sure event, it is always 1. Its formula is given as P(E) = No. of favourable outcomes / Total no. of outcomes
Calculation of the total number of times 7 can appear as a sum on rolling two cubes for 180 times
Number of cubes rolled = 2
Total number of outcomes on rolling two cubes = 36
Total possibility of getting 7 as sum = 6
The probability of getting 7 as a sum on rolling two dice only once is given by P(E1)
P(E1) = 6 / 36
= 1 / 6
She repeated the process 180 times so the needed probability, P(E) is obtained by multiplying 180 by P(E1)
P(E) = 180 × (1 / 6)
P(E) = 30
Hence, the required probability of getting 7 as the sum is given by 30.

What is dopamine?Dopamine, also known as DA or 3,4-dihydroxyphenethylamine, is a neuromodulatory chemical with a variety of crucial functions in cells. It is an organic substance that belongs to the phenethylamine and catecholamine families. About 80% of the catecholamines in the brain are made up of dopamine. It is an amine produced by removing a carboxyl group from a molecule of L-DOPA, which is used as a precursor and is produced in the kidneys and brain. Plants and the majority of animals can produce dopamine as well. Dopamine performs the role of a neurotransmitter in the brain, which is a substance secreted by neurons (nerve cells) to communicate with other nerve cells. Although neurotransmitters are only produced in some parts of the brain, they have a systemic impact on numerous areas.

The enrollment of a community college last
year was 4500 students. It increased by 5%
this year. What is the enrollment this year at
the community college?
Answer:
4725 Students
Step-by-step explanation:
First, multiply 4500 by 0.05 (which is 5% in decimal format.) You should get 225. Next, add 225 to the original value of 4500; you should get the answer, which is 4725 :)
Answer:
4725 Students
Step-by-step explanation:
To find the total enrollment of the community college this year, all we have to do is add the previous year's enrollment to 5% of the same value.
So...
Previous enrollment: 4500
5% of Previous enrollment = 0.05 * 4500 = 225
This year's enrollment = 4500 + 225 = 4725
So the final answer is 4725 students.
