The left side is divisible by 3, then q = 3t:

The least m and t would be m = 5 and t = 7.

Then:

Proof:

the time between high and low tide i 7. 8 hour. At high tide the depth of water i 19. 2 feet, while at low tide the depth i 5. 1 feet. So roughly 2 hours and 15 minutes, the depth will be 12 feet

What is depth?

(0,6)

(8,20)

(16,6)

y = C*sin( k*pi*x) + 6 since (0,6) is given

C(sin(k*pi*8) + 6 = 20

C(sin(k*pi*8) = 14 <--- label this equation ALPHA

Also,

C(sin(k*pi*16) + 6 = 6

C(sin(k*pi*16) = 0

since C cannot be zero,  k*pi*16 must be 180 = pi

                                          k*16 = 1

 k = 1/.16

C(sin( (1/16)*pi*8) = 14

C ( sin (pi/2) ) = 14

C = 14

D(t) = 14 sin( (pi/16) t ) + 6 where D is the depth and t is time

12 = 14 sin((pi/16)t) + 6

6/14 = sin((pi/16)t)

What is amount ?

Mass nouns are referred to by the word amount. Count nouns are referred to as numbers.

To illustrate the process of thinking, tets assume there are no people who passed all subjects.

40% (Maths) - 10%(+sceince) - 15% (+english) = 15% only maths

45% - 10% - 20% = 15% only science

55% - 20% - 15% = 20% only english.

That gives

15+15+20 = 50% of the students passing only one course

10+20+15 = 45% of students passing only 2 courses

… that’s 95% together …

… but we need to get to 100%; obviously.

If we assume there are X% students that passed in all 3 courses, then from the first line, we substracted this person twice: (once for +science, and once for +english). Considering we only need to substract ’m once, that’s the same as substracting twice and adding once. we get:

40% (Maths) - 10%(+sceince) - 15% (+english) + X% = 15+X % only maths

and likewise

45% - 10% - 20% + X= 15 +X % only science

55% - 20% - 15% +x X= 20 +X % only english.

Now, for the students who passed exactly 2 classes, that’s

10 - X % only maths and science

20 - X %

15 - X%

And of course, the amount of students who passed all three exams: X.

This gives us

(15+X) + (15+X) + (20+X) + (10-X) + (20 - X) + (15 - X) + X = 100

95 + X = 100

X = 5

Or, 5% of students passed all 3 tests.

edit: this answer assumes all students pass at least one test. The actual summation should be: As pointed out with the first line, if that answer is

Therefore, 20 is the lowest of the four numbers.

An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.

Positive, negative, and zero are all examples of integers.

The Latin word "integer" signifies "whole" or "intact." Thus, fractions and decimals are not included in integers.

According to our question-

4 numbers added together yields the product 4612 - 1.

The least of the four integers is the required information. Let N-2, N-1, N, and N + 1 be the numbers.

According to our calculations

, (N - 2)(N)(N + 1)(N - 1) = 4612 - 1 (N - 2)(N)(N + 1)(N - 1)- (4612 - 1) = 0

This results in N4 - 2N3 - N2 + 2N - 212520 = 0.:

(N + 21)(N - 22)(N2 - N + 460) = 0. N = 22 or -21 are hence potential solutions. However, the necessity for positive integers results in

N = 22 as a potential solution.

Because of this, where the four numbers are N-2, N-1, N, and N + 1, we get the following numbers:

22 -2, 22 -1, 22 + 1, which equals

False. While using the right sampling technique can increase the probability of getting sample mean values that are close to population mean values.

A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of people from which a statistical sample is taken in statistics.

The sample mean is the mathematical average of values selected at random from the population. The population mean is a representation of the population's real mean.

It is impossible to ensure that the sample mean and population mean will be a perfect match. This is because sampling has intrinsic variability and randomness, which can cause discrepancies between the sample and the population even in studies that are carefully planned. Additionally, there could still be some variability or error in the estimates even if the sample mean is quite near to the population mean, which might have an impact on the accuracy of the findings.

Answer:

Step-by-step explanation:

In linear equation,    x = 1  is the maximum height, in feet, reached by the pebble.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                  Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

The height of the pebble over time is modeled by the equation

        y = -16x2 + 32x + 80

At the maximum height, the final velocity of the pebble is zero.

The velocity of the pebble will be obtained by taking the derivative of the given equation.

That is

                y' = dy/dx

                    = d/dx (-16x2 + 32x + 80 )

                    = -32x + 32

At the maximum height, y' = 0 .

So,

        -32x + 32 = 0

  32x = 32

    x = 32/32

    x = 1

The closest percentage volume that has drained out is 46%

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

V(t) = 4522(0.94)^t

The initial volume is calculated when t = 0

So, we have

V(0) = 4522(0.94)^0

Evaluate

V(0) = 4522

The new volume is calculated when t = 10

So, we have

V(10) = 4522(0.94)^10

Evaluate

V(10) = 2435.62

The percentage is then calculated as

Percentage = (V(10) - V(0))/(V(0))

Inequality is 2x+178 >=2000. and Solution set is x>=911 i.e., the no: of cans that Shane should have collected

The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities1, is at the core of social justice theories. However, because it frequently has different meanings to different people, it is prone to misunderstanding in public discourse. However, some distinctions are shared.

Lifetime Inequality (the distribution of incomes across households or individuals over a person's lifetime), Inequality of Wealth (the distribution of wealth across households or individuals at a particular point in time), and Inequality of Opportunity (the impact on income of factors that people cannot control) are all related concepts.

Let the number of cans collected by Shane = x and the number of cans collected by Abha = y.

It is given that, Abha collected 178 cans more than Shane.

So, we have, .

Since, they both have to collect cans no less than 2000 i.e. greater than or equal to 2000.

So, the equation representing the situation is,

Shane + Abha ≥ 2000

i.e. y + x ≥ 2000

Thus, by substitution we have,

Inequality for the number of cans Shane collected is .2x+178 >=2000.
