Answer:

14. Three points tat are not collinear

Three points that are not colinear consist of a line and a third point, therefore, joining all three points form a flat figure having a length and a width which is a two-dimensional flat figure or a plane

15. A line and a point not lying on the line

Like the example above, the joining of the points results in a two dimensional figure having a length and a width also known as a planar surface

16. Two lines which intersect at a point

Given two lines that intersect at a point, joining the other end point of the two lines results in the forming of a flat figure, that can be described in two dimensions also known as a planar surface or plane

Step-by-step explanation:

A plane in mathematics is a flat surface that has only two dimensions and extends infinitely in all directions

The true statement about the number 2^(-3) is that it is equal to 0.125, not -8

I'm sorry, but the statement "2-^3 is equal to -8" is not true. The correct calculation for 2 raised to the power of -3 is as follows:

2^(-3) = 1 / (2^3) = 1 / 8 = 0.125

The exponent of -3 signifies that we are calculating the reciprocal or inverse of the base number raised to the power of 3. In this case, the base number is 2, and raising it to the power of -3 results in the reciprocal, which is 1/8 or 0.125.

It's important to note that negative exponents indicate the use of fractions or decimals in the calculations. In this context, the negative exponent signifies the inverse or reciprocal of the base number raised to a positive exponent.

Therefore, the true statement about the number 2^(-3) is that it is equal to 0.125, not -8.

It's crucial to understand the concept of exponentiation and the rules associated with it. Negative exponents have specific meanings and should be handled correctly to avoid mathematical errors or misunderstandings.

Answer:

The number is 8

Step-by-step explanation:

You subtract 2.5 from 58.5 which would be 56 and divided that by 7 which would give you he number 8.

Step-by-step explanation:

m1=-2

m1m2=-1

-2m2=-1

m2=1/2

y+5/x+4=1/2

so 2y+10=x+4

2y-x=-6

Answer:

\(y=\frac{1}{2}x-3\)

Step-by-step explanation:

Hi there!

We are given the equation y=-2x+5 and we want to find the equation of the line that is perpendicular to that line, and pass through the point (-4, -5)

Perpendicular lines have slopes that multiply to get -1.

So to find the slope of the perpendicular line: use the formula \(m_1*m_2=-1\), where \(m_1=-2\)

Substitute:

-2m=-1

Divide both sides by -2

m=\(\frac{1}{2}\)

Here's the equation of the line so far, as we know it, written in slope-intercept form (y=mx+b, where m is the slope and b is the y intercept):

\(y=\frac{1}{2}x+b\)

We need to find b.

Because we know the line passes through the point (-4, -5), we can use it to help solve for b.

Substitute -4 as x and -5 as y

\(-5=\frac{1}{2}(-4)+b\)

Multiply:

-5=-2+b

Add 2 to both sides

-3=b

Substitute -3 as b:

y=\(\frac{1}{2}x-3\)

Hope this helps!

Answer:

No because the x value does not change by 1 everytime the y value changes by 5

Step-by-step explanation:

Rate of Change = Slope

If the slope was 5, the the point on the graph would be on the coordinate (1,5)

However, the graph provided does NOT show 5 as being the slope because the line does not go through 0 and the x value does not change by 1 everytime y changes by 5.

If it did, however, it would look something like this picture.

Answer:^^^ that Guy is so wrong but the actual answer is b

Step-by-step explanation:

The inequality which represents the given phrase is 1/2(3x - 2/3) + 6 ≤  x+5​ and the solution are x ≤ -4/3.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given,

1/2(3x - 2/3) + 6 ≤  x+5​

3/2 x - 1/3 + 6 ≤  x+5​

3/2 x + 17/3 - x ≤ 5

x/2 ≤ -2/3

x ≤ -4/3

Answer:

The side length of each square is 2.12 units.

The length ad width of the rectangle are 2.12 and 4.24 units

Step-by-step explanation:

Let the width of the rectangle is x,

So, the length of the rectangle is 2x.

Area of the rectangle = 9 sq. units

\(9 = 2x \times x\) [as area = length x width]

\(\Rightarrow 9 = 2x^2\)

\(\Rightarrow x^2 = \frac{9}{2}=4.5\)

\(\Rightarrow x = 1.5\sqrt{2}=2.12\) units

So, width of the rectangle, x= 2.12 units and

the llengthof the rectangle, 2x= 2 x 2.12= 4.24 units.

After division of the rectangle into two equal square, so, the area of each square will be half of the area of the rectangle.

The area of the rectangle = 9/2=4.5 square units.

Let a be the length of the sides of the square, so

Area \(= a^2\)

\(\Rightarrow a^2=4.5\)

\(\Rightarrow\) \(a = 1.5\sqrt{2}=2.121\)

Hence, the side length of each square = 2.12 units.

The upper bound of the 90% confidence interval for the recovery time is approximately 23.696 days.

It takes more than approximately 21.257 minutes to find a parking space 90% of the time.

To find the probability that it will take more than 11 days to recover from the surgical procedure, we need to calculate the area under the normal distribution curve to the right of 11 days.

Mean (μ) = 7 days

Standard deviation (σ) = 7.92 days

We can standardize the value of 11 days using the z-score formula:

z = (x - μ) / σ

z = (11 - 7) / 7.92

z = 0.506

Using a standard normal distribution table or a calculator, we can find the probability corresponding to the z-score of 0.506. The probability is approximately 0.3051.

Therefore, the probability that it will take more than 11 days to recover is approximately 0.3051 or 30.51%.

Question 8:

To find the upper bound of the 90% confidence interval for the number of days needed to recover from the surgical procedure, we need to calculate the z-score corresponding to the desired confidence level and then find the corresponding value using the standard deviation.

Given:

Mean (μ) = 20 days

Standard deviation (σ) = 2.24 days

For a 90% confidence interval, the z-score corresponding to the upper tail probability of 0.10 (1 - 0.90) is approximately 1.645.

Using the formula for the upper bound of the confidence interval:

Upper bound = μ + (z * σ)

Upper bound = 20 + (1.645 * 2.24)

Upper bound ≈ 23.696

Therefore, the upper bound of the 90% confidence interval for the recovery time is approximately 23.696 days.

Question 9:

To find the time it takes more than 90% of the time to find a parking space, we need to calculate the z-score corresponding to the desired upper tail probability and then find the corresponding value using the standard deviation.

Mean (μ) = 15 minutes

Standard deviation (σ) = 4.89 minutes

For a probability of 90%, the upper tail probability is 1 - 0.90 = 0.10.

Using a standard normal distribution table or a calculator, we can find the z-score corresponding to the upper tail probability of 0.10, which is approximately 1.282.

Using the formula for the upper bound:

Upper bound = μ + (z * σ)

Upper bound = 15 + (1.282 * 4.89)

Upper bound ≈ 21.257

Therefore, it takes more than approximately 21.257 minutes to find a parking space 90% of the time.

Answer: (a) P(no A) = 0.935

              (b) P(A and B and C) = 0.0005

              (c) P(D or F) = 0.379

              (d) P(A or B) = 0.31

Step-by-step explanation: Pareto Chart demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.

The Pareto chart below shows the number of people and which category they qualified each public school.

(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:

P(no A) = \(1-\frac{68}{1052}\)

P(no A) = 1 - 0.065

P(no A) = 0.935

b) Probability of a grade better than D, is the product of the probabilities of an A, an B and an C:

P(A and B and C) = \((\frac{68}{1052})(\frac{258}{1052})(\frac{327}{1052})\)

P(A and B and C) = \(\frac{5736888}{1164252608}\)

P(A and B and C) = 0.0005

c) Probability of an D or an F is the sum of probabilities of an D and of an F:

P(D or F) = \(\frac{269}{1052} +\frac{130}{1052}\)

P(D or F) = \(\frac{399}{1052}\)

P(D or F) = 0.379

d) Probability of an A or B is also the sum of probabilities of an A and of an B:

P(A or B) = \(\frac{68}{1052} +\frac{258}{1052}\)

P(A or B) = \(\frac{326}{1052}\)

P(A or B) = 0.31

Answer:

.3 and most ducks are yellow - so letter c.

Step-by-step explanation:

remember: the formula for relative frequency is f/n.

f = number of times data occurred for an observation (30 red ducks picked)

n - total frequencies (100 ducks picked in total)

30/100 = 0.3 is the relative frequency of choosing a red duck.

Next,

Yellow was picked 40 out of the 100 times, so its likely that most ducks are yellow.

Answer:

C.  The relative frequency is 0.3. It is likely that most ducks are yellow.

Step-by-step explanation:

Relative frequency (or experimental probability) is calculated by dividing the recorded number of times an event happens by the total number of trials in the actual experiment.

\(\begin{aligned}\implies \sf Relative\:frequency\:(red\:duck) & = \dfrac{\textsf{Number of times a red duck was picked}}{\textsf{Total number of trials}}\\\\ & = \sf \dfrac{30}{100}\\\\ & = \sf 0.3\end{aligned}\)

The most likely color of duck in the pool is the color of duck with the highest frequency.  Therefore, it is likely that most ducks are yellow.

Using the Probability formula ,

the probability that first card is odd and second card is greater than 8 is 1/10.

Probability is defined as the total number of favourable outcomes divided by total numbers of outcomes.

We have total 10 cards between 1 to 10 there are 5 even and 5 odd numbers.

so, Total possible outcomes = 10

= {1,2,3,4,5,6,7,8,9,10}

two different cards are drawn out of 10 cards favourble outcomes ( odd card drawn on first draw) = 5

probability that first card is odd(P₁) = 5/10

numbers greater than 8 = {9,10 } = 2

probability that second card is greater than 8 (P₂)

= 2/10

Now , probability that first card is odd and second one is greater than 8 = P₁×P₂ = (5/10)×(2/10) = 1/10

Hence, total probability that first card is odd and second one is greater than 8 is 1/10 .
