You are taking a true/false quiz with 9 questions. What is the probability of getting all 9 questions correct?​

Answers

Answer 1

Answer:

If you guess do this -

.5(9)

Basically about a 4.5% chance of getting all right.

Answer 2

Answer:

Step-by-step explanation:

each question has 2 answer choices, so 1 or the 2 is correct, and to get all 9 in a row correct would be like this

1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2

because theres a 1 in 2 chance of getting each question right, and there are 9 questions

1/2^9 = 0.00195 = 0.195%

Mixed Number: 5 [tex]\frac{7}{10}[/tex]

Improper Fraction:[tex]\frac{57}{10}[/tex]

Step-by-step explanation:

A mixed number is when you express the decimal as a fraction, 0.7 is the same as [tex]\frac{7}{10}[/tex], so 5[tex]\frac{7}{10}[/tex] is your answer.

An improper fraction is a fraction where the numerator is bigger than the denominator, to do this you multipy the whole number 5, which can be written as [tex]\frac{5}{1}[/tex], by [tex]\frac{10}{10}[/tex].

[tex]\frac{5}{1}[/tex]·[tex]\frac{10}{10}[/tex]=[tex]\frac{50}{10}[/tex]

Then add 0.7, or [tex]\frac{7}{10}[/tex].

[tex]\frac{50}{10}[/tex]+[tex]\frac{7}{10}[/tex]=[tex]\frac{57}{10}[/tex]

Answer:

Positive

Step-by-step explanation:

It is going up from left to right

Hope this helps

Answer:

Positive.

Step-by-step explanation:

As you go along the x axis and the values of x increase, the values of y also increase. For example, at x = 2 the value of y is 1, and at x = 8 the value of y is 4. This means that the values of y are always increasing as you go up the x axis, so the slope is positive.

You can also tell this from the shape - the line, if read from left to right, is going up, so is positive.

look at the example. how would the quotient change if the total number of seats was 3,200 instead of 320? explain

Answers

If the total number of seats is 3200 instead of 320, then the quotient will change by a product of 10

The dividends are given as: 3200 and 320

By comparing 3200 and 320, we have:

3200 > 320 i.e. 3200 is greater than 3203200 = 320 * 10 i.e. 3200 is greater than 320 ten times

Quotient is simply the result gotten from dividing two quantities.

This means that:

If the total number of seats is 3200 instead of 320, then the quotient will change by a product of 10

11. Commercial jets fly between 30,000 ft and 36,000 ft. About how many hours of growing could
pass before the beanstalk might interfere with commercial aircrafts? Explain how you got your
answer

Answers

An exponential function is a function that increases rapidly as the time increases.

The number of hours that passes before the magical beanstalk interferes with commercial flight is approximately 9.384 hours.

Reasons:

The function that gives the height of a beanstalk is presented as follows;

b(t) = [tex]3^t[/tex]

When the height is 30,000 ft., we have;

30,000 = [tex]3^t[/tex]

㏑(30,000) = t·㏑(3)

[tex]\displaystyle t = \mathbf{\frac{ln(30,000)}{ln(3)}} \approx 9.384[/tex]

The time it would take the beanstalk to grow 30,000 ft., t ≈ 9.384 hours

Similarly, the time it would take the beanstalk to grow to 36,000 ft. is found as follows;

[tex]\displaystyle t_{36,000} = \mathbf{\frac{ln(36,000)}{ln(3)}} \approx 9.55[/tex]

The time it would take the beanstalk to grow 36,000 ft., t ≈ 9.55 hours

The number of hours it will take the beanstalk to grow to 30,000 feet at

which it might interfere with commercial aircrafts is 9.384 hours.

The sum of the measure of angle ∠AXY and angle ∠YXB is the measure of ∠AXB.

The relationship between ∠AXY and ∠YXB is that they are;

Complementary angles

Reasons:

From the diagram in the question, we have;

∠BXC = 90° Given

∠BXC and ∠BXA are linear pair angles

Therefore;

∠BXC and ∠BXA are supplementary angles, which gives;

∠BXC + ∠BXA = 180° definition of supplementary angles

Therefore;

∠BXA = 180° - ∠BXC

∠BXA = 180° - 90° = 90°

∠BXA = 90°

∠AXY + ∠YXB = ∠BXA by angle addition property

Which gives;

∠AXY + ∠YXB = 90° by substitution property

Therefore ∠AXY and ∠YXB are;

Complementary angles,  by definition of complementary angles.

solutions for the polynomial equation shown below?
5x3 + x2 + 7x – 28 = 0
A. One
B. Two or zero
C. Two
D. Three or one

Answers

Answer:

A. One

Step-by-step explanation:

Look at the last term, - 28.

It means, the product of roots is a positive number (28).

The polynomial is a degree three so it has 3 possible roots.

Positive product can be obtained if all 3 numbers are positive or 2 negative and 1 positive.

Therefore number of positive roots is one or three.

Further, double check using the graphical solution (see attached), it shows one root only. It means the other roots are complex.
