Answer 1

If B + BB is normal random Variable. a a Then (a + b B₂ ~ N (0, belt-s) +(arby's) b Be (1) then the probability P(5B₂ - 3 < 1) is approximately 0.57142.

To calculate this probability, we first need to find the standard deviation (σ) of the random variable 5B₂ - 3. B₂ is a standard normal random variable (mean = 0, variance = 1), the standard deviation of 5B₂ - 3 can be calculated as √((5²)(1) + (-3)²) = √(25 + 9) = √34 ≈ 5.83095.

Next, we convert the inequality 5B₂ - 3 < 1 into a standard normal distribution. Subtracting 3 from both sides gives us 5B₂ < 4, and dividing both sides by 5 yields B₂ < 4/5 = 0.8.

Now, we calculate the z-score for B₂ = 0.8 using the formula z = (x - μ) / σ, where x is the value (0.8), μ is the mean (0), and σ is the standard deviation (5.83095). Thus, z = (0.8 - 0) / 5.83095 ≈ 0.13723.

To find the probability, we look up the corresponding z-score in the standard normal distribution table. P(Z < 0.13723) is approximately 0.57142.

Therefore, the probability P(5B₂ - 3 < 1) is approximately 0.57142.

Answer: Based on the formula I was taught, for your first problem it'd be the option that says 813.9 ft and for the second one it'd be your option with 2076.3 square inches.

Answer: D) 813.9 inches

Step-by-step explanation:

Formula for surface area of cylinder is:

A=2πrh+2πr2

r = 6

h = 15.6

A = 2π(6)(15.6) + 2π(6)^2

A = 187.2π + 2π(36)

A = 187.2π + 72π

A = 259.2π

If π is 3.14,

A = 259.2(3.14) = 813.9

What is the quadratic equation for x^2+8x+7=-8?

Answers

After answering the given query, we can state that As a result, the quadratic equation formula for x2+8x+7=-8 is $x^2 + 8x + 15 = 0$

What is equation?

A mathematical equation is a process that links two statements and indicates equality with the equals sign (=). A mathematical assertion that proves the equality of two mathematical statements is known as an equation in algebra. For instance, the equal symbol separates the numbers 3x plus 5 and 14 in the equation 3x + 5 = 14. A mathematical formula can be used to understand the connection between the two lines that are written on opposite sides of a letter. Frequently, the emblem and the particular program are identical. as in 2x - 4 = 2, for example.

the quadratic equation for x^2+8x+7=-8, we first need to change the equation to normal quadratic form, which is ax^2+bx+c=0.

With 8 added to both edges, we obtain:

$x^2 + 8x + 15 = 0$

The factors a, b, and c are now clear:

a = 1

b = 8

c = 15

These numbers are substituted into the quadratic formula:

$x=(-b sqrt(b2 - 4ac)) / 2a\\x = (-8 + \sqrt(8^2 - 4(1)(15))) / 2(1)\\x = (-8 +/- \sqrt(64 - 60)) / 2\\x = (-8 +/- \sqrt(4)) / 2\\x = (-8 + 2) / 2$

Therefore, the options are:

x = -4 or x = -3

As a result, the quadratic formula for x2+8x+7=-8 is

$x^2 + 8x + 15 = 0$

Behind a mirror's glass, people can see a reflection of themselves. The shiny surface creates that image when light rays strike it and reflect or bounce back, creating a "mirror image." Contrary to popular belief, the reflection is not mirrored from left to right as many people believe.

The coordinates of the point A is (-3,-2)

The rule of reflection over x-axis is

(x,y)→(x,-y)

So the point A after reflecting over the x-axis becomes

A(-3,-2)→ A(-3,2)

To move the point P(x,y), a units right and b units up we use

P(x+a,y+b)

which of the following are a problem with a parallel conversion: (select all that apply) :a) there is a higher riskb) the old hardware might failc) there is a lower riskd) the users have to enter data into both systemse) there is an abrupt conversion

Answers

A parallel conversion is a method of implementing a new system in which the old and new systems run simultaneously for a period of time. While this approach can have its benefits, there are also potential problems that may arise.

One of the problems with a parallel conversion is that there is a higher risk, as there are two systems running at the same time, which can be costly and require additional resources. Another problem is that the old hardware might fail, which can cause data loss or delays in the conversion process. On the other hand, a lower risk may not be applicable in a parallel conversion because the risk factor is already high. Also, the users have to enter data into both systems, which can be time-consuming and prone to errors. Finally, an abrupt conversion is not applicable in a parallel conversion because both systems are running together. Overall, the parallel conversion method requires careful planning and execution to minimize the potential problems and ensure a smooth transition.

The area of the 10th floor is 5294.196 ft² if the ground floor(floor 0) is the largest and the floor space is reduced by 8.8% per floor.

It is given that the ground floor has an area of 13,300.0 ft².

If the floor space is reduced by 8.8% per floor, then we need to find the area of a 10th floor.

What is an exponential function?

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent :

$y=a^{x}$, where a is a constant and a>1.

We know we can find the exponential decrease by the below formula:

$y=a(1-r)^{n}$

a=13,300.0 ft², r=0.088 and n=10

⇒$y=13,300(1-0.088)^{10}$

⇒$y=13,300(0.912)^{10}$

⇒$y=5294.196 ft^{2}$

3m - 6 - 2m = 3 how do i solve for m?

Answer:

m=9

Step-by-step explanation:

3m-6-2m=3

Combine like terms

3m-2m=1m

1m-6=3

Add 6 to both sides

1m=9

Divide both sides by 1

m=9

Hi there! Your answer is m = 9

Please see the explanation for a clear understanding to the problem.

Any questions about the answer/explanation, feel free to ask in comments! :)

Step-by-step explanation:

Goal

Solve the equation for m-term.

Given

Equation

$\Large{3m-6-2m=3}$

Step 1

Combine like terms.

Like terms are the terms have same variables. For example, 2m and 3m. 2m and 3m both are like terms because they both have same variable which is m-term.

But 2m and 3a are not like terms because 2m has m-term as a variable but 3a has a-term as a variable. Both are terms but not like terms.

From the equation:

$3m-2m=3+6$

Since we combine like terms, we can't combine a constant with a variable so we move to the side where they are alike.

Evaulate 3m-2m = m and 3+6 = 9

$m = 9$

There aren't really much steps solving this. The next step is going to be how to check an answer. It's useful when you are not certain or sure about the answer that you get. If you are not certain on the answer, this step is highly advised for a beginner.

Optional Steps - Answer Check

Step 2

Substitute m = 9 in the equation.

The step is optional as said. From the equation:

$3m-6-2m=3$

We can do this two ways which are when we simplify the equation then substitute in the value of m or we substitute m-value first then simplify/evaluate.

I will be demonstrating these two steps to you.

Step 2.1

Simplify/Evaluate before Substitution

$3m-6-2m=3\\3m-2m=3+6\\m=9\\9=9$

Step 2.2

Substitution before Evaluation/Simplify

$3m-6-2m=3$

Substitute m = 9 in the equation.

$3(9)-6-2(9)=3\\27-6-18=3\\9-6=3\\3=3$

Notice that no matter which method you use, you'd still get the same answer. Since the equation is true for m = 9. Therefore, the solution is m = 9.

Wendy and Connor each deposit 8,300 into accounts that earn 3.5% interest for 25 years Wendy's account earns annual simple interest sand Connor's account earns an annual compound interest who will earn more interest of 25 years and how much interest they will earn

Answers

Answer:

Connor will earn more interest because he is getting compound interest.

Step-by-step explanation:

I have to assume in this case that the interest is 3.5% Per year:

Simple Interest = P(r + t)

{P = Principle, r = interest rate, t = time)

Wendy = $8,300 x (3.5% x 25)

Wendy = $7,262.50 (2 d.p)

Wendy = $8,300 + $7,262.50

Wendy = $15,562.50

Compound Interest = $P (1 +r )^{t}$

{P = Principle, r = interest rate, t = time)

Connor = $8,300 x $(1 + 0.035)^{25}$

Connor = $19,614.93

Wendy's Interest = $15,562.50 - $8,300 = $7,262.50

Connor's interest = $ 19,614.93 - $8,300 = $11,314.93

26% of all college students major in STEM (Science, Technology, Engineering, and Math). If 39 college students are randomly selected, find the probability that exactly 12 of them major in STEM. Round to 4 decimal places.

Answers

The probability of exactly 12 from 39 college students majoring in STEM is $0.1776$

What is the probability of a specific number of STEM majors?

To find the probability of exactly 12 out of 39 college students majoring in STEM, we can use the binomial probability formula.

The formula is P(X=k) = (n choose k) * p^k * (1-p)^(n-k).

Data;

n = 39, k = 12, p = 0.26, and (n choose k) = 39 choose 12 = 3,720.

Plugging in the values:

P(X=12) = 3,720 * 0.26^12 * 0.74^27

P(X=12) ≈ 0.1776
