Answer 1

Answer:

0.488

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Here, n = 3 and p = 0.2.

The complement of at least 1 is at most 0.

P(r ≥ 1) = 1 − P(r = 0)

P(r ≥ 1) = 1 − ₃C₀ (0.2)⁰ (0.8)³⁻⁰

P(r ≥ 1) = 1 − (0.8)³

P(r ≥ 1) = 0.488

Step-by-step explanation:

additive inverse example:Using the same approach, if x is a negative number, then its additive inverse is equal and opposite in sign to it. This means that the additive inverse of a negative number is positive. For instance, if x equals -12, then its additive inverse is y = 12.

Which of the following is a quadratic equation that has the roots x = 3 and x = −4?

Answers

Answer:

x^2 + x = 12

Step-by-step explanation:

(x - 3)(x + 4) = 0

x^2 + 4x - 3x - 12 = 0

x^2 + x - 12 = 0

x^2 + x = 12

The quadratic equation that has the roots x = 3 and x = −4 will be x²+x-12=0.

What is a quadratic equation?

Any equation using the formula ax² + bx + c = 0 When x is a variable and a, b, and c are any real values; a quadratic equation is one where a≠0.

It is given that the quadratic equation that has the roots x = 3 and x = −4.

We know that one such equation is provided by x²-(a+b)x+ab=0 if a and b are the roots of a quadratic equation.

x²-(a+b)x+ab=0

Substitute the value of an as 3 and b as -4.

x²-(3-4)x+(3)(-4)=0

x²-(-1)x-12=0

x²+x-12=0

Thus, the obtained quadratic equation will be x²+x-12=0.

Starting with the number 10, build a sequence of 5 numbers.

Answers

Answer:

10, 26, 74, 218, 650

Step-by-step explanation:

n * 3 - 4

Answer:

The sequence of 5 terms is:  10, 26, 74, 218, 650

Step-by-step explanation:

By following the instructions, we can build the sequence by doing:

[tex]a_n= 3\,a_{n-1}-4[/tex]

So, using this formula and starting with 10 we get

[tex]a_1=10\\a_2=3\,(10)-4=26\\a_3=3\,(26)-4= 74\\a_4=3\,(74)-4=218\\a_5=3\,(218)-4=650[/tex]

Point B is the midpoint of point C and D. If CB is 14in, what is CD and BD?

Answers

Answer:

[tex]BD = 14\ in[/tex]

[tex]CD = 28\ in[/tex]

Step-by-step explanation:

Given

CB = 14in

B as midpoint

Required

Determine CD and BD

Since B is the midpoint, then the two line segments (CB and BD), we have the following relationships:

[tex]CB = BD[/tex]

[tex]CD = CB + BD[/tex]

Reorder the first equation

[tex]BD = CB[/tex]

Substitute 14 for CB

[tex]BD = 14\ in[/tex]

Taking the second equation into consideration

[tex]CD = CB + BD[/tex]

[tex]CD = 14 + 14[/tex]

[tex]CD = 28\ in[/tex]

An equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by that power could be as;

(10)n = 10(0.11515).

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Solving equations generally means finding the values of the variables used in it for which the considered equation is true.

We have to write an equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by that power.

Therefore, the equation could be as;

(10)n = 10(0.11515)

Hence, An equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by that power could be as;

(10)n = 10(0.11515).

It is said that a student’s college GPA (grade point index) can be predicted by his/her HOCS (higher- order cognitive skills) such as problem identification, analytical reasoning, and content integration skills. What other potential predictor variables, numerical and categorical, would you want to use that might lead to the development of a multiple regression model for predicting a student’s college GPA? Briefly describe the direction of the slope that each of these variables should have.

Answers

Answer:

apart from using the hoc to predict the college students gpa, some other variables can be used

1. the students intelligent quotient

2. ability to remember

3. study time

4. gym practice

Step-by-step explanation:

1. the students intelligent quotient

gpa has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.

2. ability to remember

the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction

3. study time

gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.

4. gym practice

gpa and gym practice are not related so the slope would be in a downward direction.

when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.

Answers

Answer:

The strip of 16 by 14 inches.

Let x be the corner of the square cut

Then the box would have height as x, length 16-2x and width 14-2x

v"(x) =  

Equate first derivative to 0

Solutions are

x= 2.483 and x = 7.517

Answers

Answer:

Step-by-step explanation:

The perimeter of the figure given = the sum of all sides of the figure.

Perimeter = (k² - 9k + 23) + (k² + k) + (k² + k) + (2k² - 17)

Simply the expression as follows:

Perimeter = k² - 9k + 23 + k² + k + k² + k + 2k² - 17

Combine like terms

Perimeter = k² + k² + k² + 2k² - 9k + k + k + 23 - 17 (like terms are terms with the same degree)
