Answer:

It basically means to lessen or reduct the amount.

Answer:

1.25*10^-4

2*10^-4

3.25*10^-10

Step-by-step explanation:

Step-by-step explanation:

scientific notation simply means there is one digit (unequal to 0) before the decimal point, the other digits come after the decimal point. and this is multiplied by the proper power of 10 to put this number into its correct value spot.

remember that a negative exponent means 1/...

so, 10^-1 = 1/10¹ = 1/10 or 0.1

10^-2 = 1/10² = 1/100 or 0.01

and so on.

in this exercise we just have to turn this around and find the right power of 10 for a given decimal or so.

0.000125

let's count the positions after the decimal point until the important digits begin.

right, at the 4th position after the decimal point.

so, the scientific notation is

1.25×10^-4

as when seeing this, we know that too understand the real value of that number we have take the number sequence "125" and move it to the 4th position after the decimal point.

0.0002

again, how many positions after the decimal point until the important digits start ?

right, again 4 positions.

so, the scientific notation is

2.0×10^-4

it is good style to add a 0 to provide at least one digit after the decimal point, if there are not enough digits unequal to 0.

325×10^-8

that is close to the scientific notation but violates the rule to have the first important digit before the decimal point, and the rest after the decimal point.

so, we need to transform the number sequence "325" into 3.25

remember that a number 325 is the same as 325.0

so, actually the decimal point is 2 positions too much to the right.

for 3.25 we need to bring the decimal point the 2 positions to the left.

remember that the decimal point moves one position with every multiplication or division by 10.

so, what operation do we need to move the decimal point to the left ?

to go from 325 to 32.5 - is that multiplication or division ?

right, we divided by 10.

so, divisions by 10 makes the decimal point move left (while multiplications by 10 moves it to the right).

we need to move it 2 positions to the left, so we need to divide 2 times by 10 (which is the same as dividing one time by 10×10 or 10² or 100).

but by doing this division we actually changed the value of the number. we need to counterbalance that by adjusting the multiplying power of 10.

we started with

325×10^-8

and divided the first part by 100.

325/100 = 3.25

therefore, to keep the overall value of the number the same, we need now to multiply 10^-8 by 100.

10^-8 × 100 = 10^-8 × 10^2 = 10^-6

remember, when multiplying the same numbers with exponents, we simply keep that number and add the exponents for the new exponent.

so, we actually did

325/100 × 10^-8 × 100

and the result is the correctly formatted scientific notation

3.25×10^-6

Answer:

Step-by-step explanation:

find the semiperiter (1/2 perimeter or L+W)

80 : 2 = 40

now we know that 4z + 2 + 3z + 3 = 40

we solve for z with an equation

4z + 2 + 3z + 3 = 40

7z = 40 - 2 - 3

7z = 35

z = 35 : 7

z = 5

now we find CD

3z + 3 =      (z=5)

3 * 5 + 3 =

15 + 3 =

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

check (remember pemdas)

4z + 2 + 3z + 3 = 40

The standardized residuals are -0.11, 0.75, -0.38, 2.08, and 2.16, respectively.

(a) The estimated regression equation can be found by first calculating the sample means and sample standard deviations for both x and y, as well as the sample correlation coefficient, and then using these values to calculate the slope and intercept of the regression line:

x = (6 + 11 + 15 + 18 + 20)/5 = 14

y = (7 + 7 + 13 + 21 + 30)/5 = 15.6

sx = sqrt(((6-14)^2 + (11-14)^2 + (15-14)^2 + (18-14)^2 + (20-14)^2)/4) = 4.49

sy = sqrt(((7-15.6)^2 + (7-15.6)^2 + (13-15.6)^2 + (21-15.6)^2 + (30-15.6)^2)/4) = 8.25

r = ((6-14)(7-15.6) + (11-14)(7-15.6) + (15-14)(13-15.6) + (18-14)(21-15.6) + (20-14)(30-15.6))/4sxsy

= 0.962

b = r(sy/sx) = 1.71

a = y - b(x) = -9.23

Therefore, the estimated regression equation is y = -9.23 + 1.71x.

Step-by-step explanation:

roots are where the graph intersects at x axis

The roots of the quadratic equation whose related function is graphed are 0 and 4, the correct option is C.

A quadratic equation is a second-order equation written as ax2 + bx + c = 0 where a, b, and c are coefficients of real numbers and a ≠ 0.

If b2 – 4ac > 0 roots are real and different. As the discriminant is >0 then the square root of it will not be imaginary. It has two cases.

If b2 – 4ac is a perfect square then roots are rational. As the discriminant is a perfect square, so we will have an integer as a square root of the discriminant. Hence, the roots are rational numbers.

The shape of the graph is a downward parabola on the positive x-axis therefore the roots of the graph are positive.

From the given option the roots of the equation are 0 and 4 both are positive.

The polynomial representing the area of the is 49n² - 25

The formula for area of a square is expressed as;

Area = a²

Where a is the side length

From the image shown, we can see that the side length takes the value (7n - 5)

Substitute the value into the formula

Area = a²

Area = (7n - 5)²

Area = (7n - 5) ( 7n + 5); this is so because of the difference of two squares

Expand the bracket

Area = 49n² + 35n - 35n - 25

collect like terms

Area = 49n² - 25

Thus, the polynomial representing the area of the cube is 49n² - 25

the linear momentum of the particle when x = 8 m is approximately 8.06129 Ns.

To find the linear momentum when x = 8 m, we need to calculate the vertical velocity component vy at that position. Using the equation for y(x) = -4sin(2x), we can differentiate it with respect to x to find the vertical velocity component vy.

By differentiating y(x) = -4sin(2x) with respect to x, we obtain vy = -8cos(2x).

Substituting x = 8 into vy = -8cos(2x), we get vy = -8cos(16).

Now, we can calculate the linear momentum p by multiplying the mass (m = 4 kg) with the magnitude of the velocity vector, which is given by the square root of the sum of the squares of the horizontal and vertical velocity components.

Using the given values, p = 4 × \(\sqrt{vx^{2} +vy^{2} }\) = 4 × \(\sqrt{2^{2} }\) + \((-8cos(16))^{2}\)

Evaluating this expression, we find p ≈ 8.06129 Ns.

By the principle of mathematical induction, we have proved that P(n) is true for all positive integers n, which completes the proof.

Let P(n) be the statement "If n straight lines are drawn in the plane, the regions formed can be colored with two colors in such a way that no two regions that share a common edge have the same color."

Base case: P(1) is true, as there is only one line and it divides the plane into two regions that can be colored with two different colors.

Inductive hypothesis: Assume P(k) is true for some arbitrary value of k, where k is a positive integer. That is, we assume that if k straight lines are drawn in the plane, the regions formed can be colored with two colors in such a way that no two regions that share a common edge have the same color.

Inductive step: We want to prove that P(k+1) is true, i.e., if (k+1) straight lines are drawn in the plane, the regions formed can be colored with two colors in such a way that no two regions that share a common edge have the same color.

Consider the (k+1)th line. It intersects the existing k lines in k+1 points, dividing the plane into k+2 regions. We can choose one of these regions to be unbounded and assign it one color, say white. We can then color the remaining k+1 regions with two colors (white and black) such that no two regions that share a common edge have the same color, by using the coloring scheme for P(k) that we assumed to be true.

Now we have colored k+2 regions in total, with no two adjacent regions sharing the same color. Therefore, P(k+1) is true.

(a) The population proportion of success is given as 53%. This means that 53% of the population is expected to have a successful outcome from the flu shot.

To calculate the population proportion of success, we are given that the flu vaccine is effective for 53% of patients administered the shot. This means that 53% (or 0.53) of the entire population is expected to have a successful outcome from the flu shot.

(b) The mean of the sampling distribution of the sample proportion is also 53%.

The mean of the sampling distribution of the sample proportion can be calculated using the same population proportion of success, which is 53%. The sampling distribution represents the distribution of sample proportions if multiple samples of the same size are taken from the population. Since the mean of the sampling distribution is equal to the population proportion, the mean in this case is also 53%.

(c) The standard deviation of the sampling distribution of the sample proportion is approximately 0.017.

To calculate the standard deviation of the sampling distribution of the sample proportion, we use the formula:

\(\sigma = \sqrt{\frac{p \cdot q}{n}}\)

where σ represents the standard deviation, p is the population proportion of success (0.53), q is the complement of p (1 - p, which is 0.47), and n is the sample size (85).

Plugging in the values, we get:

\(\sigma = \sqrt{\frac{0.53 \cdot 0.47}{85}}\)

Calculating this expression, we find:

\(\sigma \approx \sqrt{\frac{0.0251}{85}} \approx \sqrt{0.000295} \approx 0.0171\)

Rounding this value to three decimal places, the standard deviation of the sampling distribution of the sample proportion is approximately 0.017.

The values of p1, p2, p3 that minimize Var(X) are p1 = 0, p2 = 1/3, and p3 = 2/3.

We can use the following formulas to find the variance of X:

Var(X) = E[X^2] - (E[X])^2

E[X] = p1 + 2p2 + 3p3

E[X^2] = p1 + 4p2 + 9p3

Substituting these expressions into the formula for the variance, we get:

Var(X) = p1 + 4p2 + 9p3 - (p1 + 2p2 + 3p3)^2

Simplifying this expression, we get:

Var(X) = -\((p1^2 + 2p2^2 + 3p3^2) + 2p1p2 + 6p1p3 + 4p2p3\)

To maximize Var(X), we want to maximize this expression subject to the constraint p1 + p2 + p3 = 1. We can use Lagrange multipliers to find the maximum. Let:

L(p1, p2, p3, λ) = -\((p1^2 + 2p2^2 + 3p3^2) + 2p1p2 + 6p1p3 + 4p2p3 + λ(1 - p1 - p2 - p3)\)

Taking partial derivatives and setting them equal to zero, we get:

-2p1 + 2p2 + 6p3 - λ = 0

4p1 - 4p2 + 4p3 - λ = 0

6p1 + 8p2 - 6p3 - λ = 0

p1 + p2 + p3 = 1

Solving these equations, we get:

p1 = 2/7, p2 = 3/7, p3 = 2/7, λ = 4/7

Therefore, the values of p1, p2, p3 that maximize Var(X) are p1 = 2/7, p2 = 3/7, and p3 = 2/7.

To minimize Var(X), we want to minimize the expression \(-(p1^2 + 2p2^2 + 3p3^2) + 2p1p2 + 6p1p3 + 4p2p3\) subject to the constraint p1 + p2 + p3 = 1. We can use the same Lagrange multiplier method to find the minimum. Taking partial derivatives and setting them equal to zero, we get:

-2p1 + 2p2 + 6p3 - λ = 0

4p1 - 4p2 + 4p3 - λ = 0

6p1 + 8p2 - 6p3 - λ = 0

p1 + p2 + p3 = 1

Solving these equations, we get:

p1 = 0, p2 = 1/3, p3 = 2/3, λ = 2/3

Therefore, the values of p1, p2, p3 that minimize Var(X) are p1 = 0, p2 = 1/3, and p3 = 2/3.

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 0) ← 2 points on the line

m = \(\frac{0-(-2)}{1-0}\) = \(\frac{0+2}{1}\) = \(\frac{2}{1}\) = 2

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = 2x - 2 ← equation of line

Answer:

y = 2x - 2

Step-by-step explanation:

The equation y = mx + b is a standard form of a linear equation in one variable. It represents a straight line on a graph

In this equation, y is the dependent variable, which is the variable that is being measured or predicted. The independent variable is x, which is the input or cause in the relationship.

The coefficient m is the slope of the line, which tells you the rate of change between the two variables. It represents how much the value of y changes for each unit change in the value of x. A positive slope means that the line goes up as you move from left to right, while a negative slope means that the line goes down.

- Our slope is positive

- slope (m) = rise / run = 2/1 = 2

The constant b is the y-intercept, which is the point where the line crosses the y-axis. It represents the value of y when x is equal to 0.

- Our y-intercept is -2

m is 2 and b is -2, the equation y = 2x - 2 represents a line with a slope of 2 and a y-intercept of -2. This means that for every 1 unit increase in the value of x, the value of y increases by 2 units, and the line crosses the y-axis at the point (0, -2).
