On solving the provided question, we got that The 90% confidence interval for the population mean mu is (140.4, 147.6)

A measure of how far the data are from the mean is called standard deviation (or). Data that have a low standard deviation are more likely to be centered around the mean than those that have a high standard deviation.

xbar = 144 (sample mean)

s = 12 (sample standard deviation)

n = 30 (sample size)

z = 1.645 (critical value at 90% confidence; use a calculator or table to compute this value)

[tex]The lower limit of the confidence interval is L, which is found by\\\\L = xbar - z(s/sqrt(n))\\L = 144 - 1.645(12/sqrt(30))\\L = 140.395985571616\\L = 140.4\\[/tex]

Similarly the upper limit U is

Answer:

2 1/4

Step-by-step explanation:

Subtract the whole numbers first:

8 - 6 = 2

To subtract the fractions, change 1/2 to 2/4 since they equal the same thing and 2/4 has the same denominator as 1/4:

2/4 - 1/4 = 1/4 <--- all we needed to do was subtract the numerators

Your final answer is 2 1/4.

Lela is making peach pies. She uses 9 peaches for each pie. If she uses 18 peaches for 2 pies and 36 peaches for 4 pies, how many peaches will she need for 7 pies?

As, Lela is using 9 peaches for each pie.

Thus, she used 18 peaches for 2 pies, which is 2 times 9 and 36 peaches for 4 pies, which is 4 times 9. Therefore, to make 7 pies, she would need :

Peaches used for one pie = 9

=> Peaches used for 7 pies = 9 × 7

=> Peaches needed for 7 pies = 63

Hence, she will need 63 peaches to make 7 pies.

A line 'a' and line 'b' are perpendicular to each other.

We know that the formula for the slope of line passing through two points (x1, y1) and (x2, y2) is,

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

A line 'a' passes through points (-3,5) and (0,0)

Let m1 be the slope of line 'a'

m1 = (0 - 5)/(0 - (-3))

m1 = -5/3

A line 'b' passes through points (3,5) and (0,0).

Let m2 be the slope of line 'b'

m2 = (0 - 5)/(0 - 3)

m2 = (-5)/(-3)

m2 = 5/3

We can observe that, m1 * m2 = -1

Since the product of slopes of the lines is -1, the lines a and b are perpendicular.

Therefore, the lines are perpendicular.

The value of the equation log(3 47) is about 4.235.

The power to which a number must be increased in order to obtain another number is known as a logarithm. For instance, since ten raised to the power of two equals 100, the base ten logarithm of 100 is 2: log 100 = 2.

Given that the approximate values of log(3) and log(47) are 1.1 and 3.85, respectively,

we must determine the approximate value of log(347).

log(a × b) = log(a) × log(b)

we get ,

log(3 × 47) = log(3) × log(47)

Answer: 1

Step-by-step explanation:

As the out comes are (3,6), (5,6), (5,3), (5,4), (5,5),(3,5) when you rolled an odd number first so the probability of rolling a sum greater than 7 is 1/6

The probability is equal to the variety of possible outcomes. the total number of outcomes that could occur. For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). it will be written as P(heads) = 1/2.

Information about the possibility that something will happen is provided by probability. For instance, meteorologists use weather patterns to forecast the likelihood of rain. Probability theory is utilized in epidemiology to comprehend the connection between exposures and the risk of health outcomes.

There are total 36 possible outcomes of two dices when they are rolled.

N=36

now we have to consider the out comes having sum greater than 7

which are;

(2,6),(3,5),(3,6),(4,4) ,(4,5),(4,6),(5,3),(5,4),(5,5) ,(5,6),(6,2),(6,3),(6,4),(6,5),(6,6)

and now selecting only those having first number is odd

so they are:

(3,5),(3,6),(5,3),(5,4),(5,5),(5,6)

now using probability formula;

Probability = favorable outcomes /total outcomes

Probability of rolling an odd number on a single die is 3/6, or 1/2. This is because there are three odd numbers (1, 3, and 5) on a standard six-sided die, and the probability of rolling any given number is 1/6.

Probability is a metric used to determine how likely an event or result is to occur. A decimal or fraction between 0 and 1 is typically used to express it, with 0 denoting that the event will not occur and 1 denoting that it will occur without a doubt. For instance, the likelihood of rolling a 6 on a conventional six-sided die is 1/6 since there is only one scenario out of the six conceivable events that will result in rolling a 6. By dividing the number of desired outcomes by the total number of potential possibilities, one may compute probability. In general, the more likely an event is to occur, the greater its probability.

Richard is 23years old and Thiago is 5years old

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation.

From the question,

Let R stands for Richard

     T stands for Teo

we were told that the combined age of Richard and Teo is 28

i.e

R + T = 28 ......eqn (i)

we were also told that  Richard is 13 years older than twice Teo’s age

i.e

R = 2T + 13 .....eqn(ii)

substituting 2T + 13 for R in eqn (i)

(2T+13)+T = 28

expanding the bracket

3T + 13 = 28

collecting like terms

3T = 28 - 13

3T = 15

T = 15/3

T = 5

Teo age is 5years

From eqn (i)

R + T = 28

R + 5 = 28

R = 28 - 5

R = 23

Hence, Richard age is 23years

From eqn (ii)

R = 2T + 13

substituting for R in the eqn

23=2T+13

collecting like terms

23-13=2T

10=2T

T=10/2

T=5

Hence. Thiago age is 5years

Answer: The square root of 169 is 13, so the two solutions for x are:

x = (13 + 13) / 4 = 3.25

x = (13 - 13) / 4 = -0.25

Since the quadratic expression 2x^2 - 13x - 5 equals 0 when x is either 3.25 or -0.25, the factors of this expression are (x - 3.25)(x + 0.25).

In summary, the factors of the first quadratic expression are (x + 1.056)(x + 5.937), the factors of the second expression are (x - 0.75)(x + 3.75), and the factors of the third expression are (x - 3.25)(x + 0.25).

Step-by-step explanation: To find the factors of a quadratic expression, we can use the quadratic formula. The quadratic formula states that for a quadratic expression of the form ax^2 + bx + c = 0, the solutions for x are given by the formula x = (-b ± sqrt(b^2 - 4ac)) / (2a).

In the first equation, a is 9, b is 31, and c is 20. Plugging these values into the quadratic formula, we get:

x = (-31 ± sqrt(31^2 - 4 * 9 * 20)) / (2 * 9)

This simplifies to:

x = (-31 ± sqrt(961 - 720)) / 18

This further simplifies to:

x = (-31 ± sqrt(241)) / 18

We can find the value of the square root by using a calculator or by remembering some common square roots. The square root of 241 is approximately 15.937, so the two solutions for x are:

x = (-31 + 15.937) / 18 = -1.056

x = (-31 - 15.937) / 18 = -5.937

Since the quadratic expression 9x^2 + 31x + 20 equals 0 when x is either -1.056 or -5.937, the factors of this expression are (x + 1.056)(x + 5.937).

We can use the same approach to find the factors of the other two quadratic expressions. For the second expression 2x^2 + 7x - 4, the values of a, b, and c are 2, 7, and -4, respectively. Plugging these values into the quadratic formula, we get:

x = (-7 ± sqrt(7^2 - 4 * 2 * -4)) / (2 * 2)

This simplifies to:

x = (-7 ± sqrt(49 + 32)) / 4

This further simplifies to:

x = (-7 ± sqrt(81)) / 4

The square root of 81 is 9, so the two solutions for x are:

x = (-7 + 9) / 4 = 0.75

x = (-7 - 9) / 4 = -3.75

Since the quadratic expression 2x^2 + 7x - 4 equals 0 when x is either 0.75 or -3.75, the factors of this expression are (x - 0.75)(x + 3.75).

For the third expression 2x^2 - 13x - 5, the values of a, b, and c are 2, -13, and -5, respectively. Plugging these values into the quadratic formula, we get:

x = (13 ± sqrt(13^2 - 4 * 2 * -5)) / (2 * 2)

This simplifies to:

x = (13 ± sqrt(169 + 40)) / 4

The height of the flagpole, found using the ratio of the sides of similar triangles is 12.975 meters

Similar triangles are triangles  in which two angles of one triangle  are congruent to two angles in the other triangle, such that they have the same shape.

The parameters that can be used to find the height of the flagpole are;

Distance of the mirror from the flagpole = 8.65 meters

Distance of Feng on the other side of the flagpole = 1.1 meters

The height from Feng's eyes to the ground = 1.65 meters

According to the law of reflection, the angle of incident and the angle of reflection are the same

The angle made by Feng and the ground = Angle made by the flagpole and the ground = 90°

The triangle formed by the Feng and the flagpole are therefore similar by AA similarity postulate

The ratio of corresponding sides of similar triangles are the same, therefore;

[tex]\dfrac{1.65}{Height\, of \, the \, flagpole} = \dfrac{1.1}{8.65}[/tex]
