Answer: Mean = 21 , Variance = 6.3 , standard deviation =2.51

Step-by-step explanation:

Formula for the mean, variance and standard deviation of the binomial experiment :

\(Mean = np\\\\ Variance = np(1-p)\\\\ Standard\ deviation = \sqrt{variance}\)

, where n= sample size , p= population proportion.

As per given, p= 70%=0.7 , n=30

\(Mean = 0.7\times30=21\\\\Variance =(30)(0.7)(1-0.7)=(21)(0.30)=6.3\\\\ Standard\ deviation = \sqrt{6.3}\approx2.51\)

Hence, Mean = 21 , Variance = 6.3 , standard deviation =2.51

Answer:

84330

Step-by-step explanation:

The compound interest formula gives the value of an investment.

 A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years. Using your given values, we can solve for P.

 110,000 = P(1 +0.019/12)^(12·14)

 P = 110,000/(1 +0.019/12)^(12·14) ≈ 110,000/1.00158333...^168

 P ≈ 110,000/1.30446

 P ≈ 84326.04 ≈ 84,330 . . . . dollars

The fundamental color-programming unit on a computer screen or in a digital image is the pixel, a word that was created from the phrase "picture element." Consider it more as a conceptual than a physical unit. In a digital display, pixels are the smallest unit.

The smallest component of a visual display or digital image is a pixel, also known as a picture element. A grid of pixels is used to create computer screens. Red, blue, and green illumination components make up each pixel, which may produce millions of distinct colors by combining them in various ways and at various intensities.

For instance, a computer with a display resolution of 1280 x 768 will create up to 98,3040 pixels on a display screen. The number of pixels per inch of the monitor screen affects image quality; more pixels per inch produce better images.

There are 144 ways to list the digits {1, 1, 2, 2, 3, 4, 5} such that two identical digits are not in consecutive positions.

We have to list the digits {1, 1, 2, 2, 3, 4, 5} so that two identical digits are not in consecutive positions. We can use the knowledge of permutations and combinations to solve this problem. We can start by selecting the positions for the distinct digits, i.e., (3, 4, 5). There are 3 distinct digits, so there are 3! = 6 ways to arrange them.

Once we have placed the distinct digits, we can place the two 1's and two 2's in the remaining positions such that no two identical digits are in consecutive positions. To do this, we can use the following approach:

We can start by placing one of the 1's. There are 4 positions available for the first 1.

We can then place one of the 2's. There are 3 positions available for the first 2.

We can then place the second 1. There are 2 positions available for the second 1.

We can then place the second 2. There are 1 positions available for the second 2.

Therefore, the total number of ways to list the digits {1, 1, 2, 2, 3, 4, 5} such that two identical digits are not in consecutive positions is:

6 (arrangements of distinct digits) x 4 x 3 x 2 x 1 = 144.

The solution of the equation 16g + 3 = 4 - 13g is g = 1/29

An equation is a statement that two expressions are equal. In other words, it's a mathematical sentence that says that the value on the left side of the equation is equal to the value on the right side.

In your problem, you have the equation:

16g + 3 = 4 - 13g

To solve this equation, the goal is to isolate the variable "g" on one side of the equation, so we can find its value. To do that, we need to use some algebraic techniques.

First, we can simplify the equation by combining like terms. We can add 13g to both sides of the equation to get:

16g + 13g + 3 = 4

Now we can combine the like terms on the left side of the equation:

29g + 3 = 4

Next, we want to isolate the variable "g" on one side of the equation. To do that, we can subtract 3 from both sides of the equation:

29g = 1

Finally, we can solve for "g" by dividing both sides of the equation by 29:

g = 1/29

So the solution to the equation is g = 1/29.

The complete question is added as an attachment

To calculate P(4<X≤12), we use the following equation

P(4<X≤12) = P(4<X≤8) + P(8<X≤12)

From the histogram, we have:

P(4<X≤8) = 0.1

P(8<X≤12) = 0.35

So, we have:

P(4<X≤12) = 0.1 + 0.35

Evaluate

P(4<X≤12) = 0.45

Hence, the value of P(4<X≤12) is 0.45

The system of linear inequalities whose solution is graphed is x > -3, y ≥ -4/5x - 2. Option 2 is the correct answer.

When two mathematical statements or two numbers are compared in an unequal way, it is known as an inequality in mathematics. Inequalities can generally be classified as either algebraic or numerical, or as a combination of the two. When a polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1, this is an example of a linear inequality, which is an inequality involving at least one linear algebraic expression. Several types of linear inequalities can be represented in a number of different ways.

From the given graph we see that the dotted line has intersects the x axis at -3.

Since, the line is dotted we do not include -3 in the equation.

To accumulate $2,176,097.00 in his retirement account by age 65, Derek needs to make annual deposits of $5,000.00 starting on his 27th birthday and ending on his 65th birthday, assuming an 8.00% interest rate.

To determine the annual deposits Derek needs to make, we can use the future value of an ordinary annuity formula. First, we calculate the number of years between Derek's 25th and 65th birthdays, which is 65 - 25 = 40 years. Next, we calculate the future value of the retirement account using the given interest rate of 8.00%. Using the formula:

Future Value = Present Value * (1 + interest rate)^number of periods

In this case, the future value is $2,176,097.00, the interest rate is 8.00%, and the number of periods is 40. We can rearrange the formula to solve for the present value:Present Value = Future Value / (1 + interest rate)^number of periods

Substituting the values:Present Value = $2,176,097.00 / (1 + 0.08)^40 = $123,529.31 (rounded to 2 decimal places)

Now, we need to find the annual deposit amount. Since Derek starts making deposits on his 27th birthday and ends on his 65th birthday, he makes deposits for 65 - 27 = 38 years.Annual Deposit = Present Value / ((1 + interest rate)^number of periods - 1)Substituting the values:

Annual Deposit = $123,529.31 / ((1 + 0.08)^38 - 1) = $5,000.00 (rounded to 2 decimal places)Therefore, Derek must make annual deposits of $5,000.00 into his retirement account starting on his 27th birthday and ending on his 65th birthday to accumulate $2,176,097.00 by the time he turns 65.

The flux of Star B is approximately 12.44 Watts per square meter. To calculate the flux of Star B, we used the inverse square law of light and the given luminosity of Star B.

To calculate the flux of Star B, we need to use the inverse square law of light. According to this law, the flux (F) of light decreases with the square of the distance (r) from the source. The formula for flux is given as:

F = L / (4πr^2)

Where:

F = Flux (measured in Watts per square meter)

L = Luminosity (measured in Watts)

r = Distance from the source (measured in meters)

In this case, the luminosity of Star B is given as 6.98 × 10^32 Watts, and the distance from the Earth to Star B is known to be 4.38 light years. We need to convert the distance from light years to meters before plugging it into the formula.

To convert the distance from light years to meters, we can use the fact that 1 light year is approximately equal to 9.461 × 10^15 meters. So, the distance from the Earth to Star B can be calculated as follows:

Distance = 4.38 light years × (9.461 × 10^15 meters per light year)

Distance = 4.38 × 9.461 × 10^15 meters

Now, we can substitute the values into the flux formula:

F = (6.98 × 10^32 Watts) / (4π × (4.38 × 9.461 × 10^15 meters)^2)

Simplifying the expression inside the parentheses:

F = (6.98 × 10^32 Watts) / (4π × (1.673 × 10^16 meters)^2)

F = (6.98 × 10^32 Watts) / (4π × 2.807 × 10^32 meters^2)

F = (6.98 / (4π × 2.807)) × (10^32 / 10^32) Watts per square meter

F = 1.244 × 10^1 Watts per square meter

In summary, After converting the distance from light years to meters, we substituted the values into the flux formula to find that the flux of Star B is approximately 12.44 Watts per square meter.

Answer:

y=1/2x+8

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-7)/(-4-(-2))

m=-1/(-4+2)

m=-1/-2

m=1/2

y-y1=m(x-x1)

y-7=1/2(x-(-2))

y-7=1/2(x+2)

y=1/2x+2/2+7

y=1/2x+1+7

y=1/2x+8

Answer:

y = -1x - 2/2

Step-by-step explanation:

Slope is -1

B = 2/-2

Answer:

y = x - 4

Step-by-Step Explanation:

Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.

Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1  (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).

Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):

y = mx + b

-2 = 1(2) + b

-2 = 2 + b

Subtract 2 from both sides to solve for b:

-2 - 2 = 2 - 2 + b

-4 = b

Therefore, the y-intercept (b) = -4.

Hence, the equation of the perpendicular line is: y = x - 4
