The final interval notation is  F ∩ H = [7, 4] &  F ∪ H = [-∞, ∞].

What is the interval notation?

A set of real numbers known as an interval in mathematics contains all real numbers falling inside any two of the set's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 x 1.

We have,

F and H are sets of real numbers defined as follows.

F = { v l v < 4}

H = { v l v ≥ 7}

F is the set of all real numbers that are less than or equal to 4.  H is the set of real numbers greater than 7.

F U H is the union (or combination) of the two sets, so it is the set of all real numbers that are less than equal to 3 or greater than 6:

F ∩ H is the set of real numbers that are in both sets; but since F is less than or equal to 4 and H is greater than 7, there are no numbers that are in both sets.  Hence the answer is the empty set, Ø:

F ∩ H = Ø

F ∩ H = [7, 4]

F ∪ H = [-∞, ∞]

The width of a rectangle is 6 yards less than the length. The perimeter is 132 yards. Find the length and width.


Width =

Length =

Answers

The length and width of a rectangle are 36 and 30 yard respectively.

What is perimeter?

Its the sum of length of the sides used to made the given figure.

We are given that width of a rectangle is 6 yards less than the length. The perimeter is 132 yards.

Therefore, the perimeter = (2 x length)+(2 x width)

The length = 6 + w

Hence, we have;

132 = (2(6 + w))+(2w)

132 = 12 + 2w + 2w

132 = 12 + 4w

120 = 4w

w = 30

Length = 36 yard.

Thus, the length and width of a rectangle are 36 and 30 yard respectively.

Answers

The statement that best describes a sequence of transformations in which the blue figure is the image of the red figure is given as follows:

A. Rotate 90° clockwise about the origin and then dilate with respect to the origin using a scale factor of 1/2.

What are the transformations?

The horizontal side lengths on the blue figure are given as follows:

8 - 4 = 6 - 2 = 4.

The vertical side lengths on the transformed red figure is of:

4 - 2 = 3 - 1 = 2.

Hence the scale factor of the dilation is given as follows:

2/4 = 1/2.

Which means that options C and D are not correct.

The rules for each rotation are given as follows:

90º degrees clockwise: (x,y) -> (y,-x).90º degrees counter-clockwise: (x,y) -> (-y,x).

On the second quadrant, of the blue figure, we have that:

x is negative.y is positive.

On the first quadrant, of the red figure, we have that:

x is positive.y is positive.

Hence the rotation was clockwise, and option A is correct.

Two dice are rolled, find the probability that the total showing is less than 10.

Answers

The probability that the total showing is less than 10 is 5/6.

What is a expression? What is a mathematical equation? What is Probability?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -  

P(A) = n(A)/n(S)

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes

Given are two dices rolled.

The total number of favorable outcomes can be calculated as -

[a] = (1,1) to (1,6) = 6

[b] = (2,1) to (2,6) = 6

[c] = (3,1) to (3,6) = 6

[d] = (4,1) to (4,5) = 5

[e] = (5,1) to (5,4) = 4

[f] = (6,1) to (6,3) = 3

n(A) = [a] + [b] + [c] + [d] + [e] + [f] =  6+6+6+5+4+3 = 30

n(S) = 36

So, the probability of occurrence of an event 'A' -

P(A) = n(A)/n(S)

P(A) = 30/36

P(A) = 5/6

Therefore, the probability that the total showing is less than 10 is 5/6.

We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.

It is given that Becky has passed 4 scales, whereas her friend Charlotte has passed 8 of them.

Going forward, Becky has committed to passing 4 scales per week, and Charlotte has committed to passing 2 per week.

Let number of weeks be x

Becky has passed 4x + 4

4x - 2x = 8 - 4

2x = 4

x = 4/2 = 2

Becky has passed 4x + 4 = 4(2) + 4 = 8 + 4 = 12

The high school a athletic director is asked if football players are doing as well as academically asthe other students athletes.

Answers

The athletic director can therefore draw the conclusion that the average academic standing of football players is comparable to the average standing of other student athletes.

Explain the term t-distribution?Whenever the population's standard deviation is unknown and the data come from such a normally distributed population, the t-distribution characterizes the standardized distances between the sample means and the population mean.

The following formula is used to determine the test statistic:

SRS, s = 0.54, n = 40 > 30,

x = 3.18

H0: μ = 3.10

H1: μ > 3.10

α = 0.05

The t-distribution table and our alpha level of.05 are then used to determine our crucial values.

Our critical values are 2.093 for a two specimens with 19 levels of freedom and α = 0.05 level of significance.

t = x -  μ / s/√n

t = 3.18 - 3.10/ 54/√20

t = 0.66

This indicates that the measured sample mean of football players, 3.18, is 0.66 standard errors higher than the 3.10 number that was predicted. We are unable to disprove the null hypothesis because the test statistic's value is below the threshold of 2.093.

As a result, It is clear that sampling error is the only possible explanation for the discrepancy between both the sample mean as well as the hypothesized value.

The vertices of triangle ABC are A(−4, 3), B(4, 3), and C(−4, −6). The triangle is dilated with a scale factor of 3. Estimate the perimeter of the dilated figure to the nearest whole number.

Answers

The perimeter of the image of the triangle is approximately equal to 87 units.

How to determine the perimeter of the image of a triangle

In this problem we find the coordinates of the vertices of a triangle: A(x, y) = (- 4, 3), B(x, y) = (4, 3), C(x, y) = (- 4, - 6), of which we must determine the perimeter of its image, which is the result of a scale factor of 3. The perimeter is the sum of the lengths of the triangle. The length of each side of the image of the triangle can be found by Pythagorean theorem and definition of dilation:

l = √[(Δx)² + (Δy)²]

Where:

l - Side lengthΔx - Change in the x-direction.Δy - Change in the y-direction.

And the perimeter of the image of the triangle is described below:

p = k · (AB + BC + AC)

Where k is the scale factor.

First, determine the lengths of sides AB, BC and AC:

Side AB

AB = √[[4 - (- 4)]² + (3 - 3)²]

AB = 8

Side BC

BC = √[(- 4 - 4)² + (- 6 - 3)²]

BC = √[(- 8)² + (- 9)²]

BC = √145

Side AC

AC = √[(- 4 - 4)² + (- 6 - 3)²]

AC = 9

Second, determine the perimeter of the image:

p = 3 · (8 + √145 + 9)

p = 3 · (17 + √145)

p = 51 + 3√145

p ≈ 87.125

The student first prepares a saturated solution of sodium hydroxide using freshly distilled or deionized water. She measures about 5 mL with a graduated cylinder and dilutes to 1 L in a plastic bottle with freshly distilled or deionized water to make a solution that is about 0.1 M. To determine the exact concentration she puts the NaOH solution in a buret and titrates a carefully-weighed pre-dried solid acid of known molar mass. She records the volume of NaOH needed to neutralize it and repeats the process several times to determine the concentration of the NaOH solution. She calculates the concentration and uncertainty in the concentration of the NaOH from the titration data. Why can\'t the student just weigh the sodium hydroxide directly to make a standard? Select all that apply. NaOH pellets react with water. NaOH pellets react with oxygen. NaOH pellets react with hydrogen. NaOH pellets react with carbon dioxide. NaOH pellets react with nitrogen. Why did the student first prepare a saturated solution? A. Saturated solutions are higher in purity than unsaturated solutions. B. Unsaturated NaOH solutions are light-sensitive. C. She can calculate the concentration of the saturated NaOH solution from the Ksp of NaOH. D. Any sodium hydrogen carbonate formed by the reaction of NaOH with atmospheric carbon dioxide will precipitate in the saturated solution. The student prepares the NaOH solution of high purity but unknown concentration by taking about 5 mL of the supernatant at the top of the saturated solution adding it to a plastic bottle with about 1 L of freshly distilled or deionized water. The bottom of the solution contains some white solids which are likely to be (select all correct answers): sodium hydroxide sodium hydrogen sulfate sodium silicate CO2(s) H2O(s) phthalic acid sodium hydrogen carbonate Why is a plastic bottle is generally preferred to glass bottle during the above step? A. The reaction between sodium hydroxide and plastic produces plastic hydroxide. B. Sodium hydroxide renders plastic inert by a process called passivation. C. Sodium hydroxide reacts slowly with glass, forming sodium silicate. D. Sodium hydroxide reacts with polyethylene. The concentration of saturated NaOH is 50.0% w/w and the density is 1.52 g/mL. If exactly 4.00 mL were diluted to 1.000 L, what would be the concentration? Why is potassium acid phthalate (KHC8H4O4, MM = 204.227 g/mol) so widely used as a standard in acid-base titrations? Select all that apply. It is stable to air It is expensive It is easy to dry It has a slowly changing pH at the equivalence point It has a relatively high molar mass It is available in high purity A student dries the pure potassium acid phthalate (KHC8H4O4) in the oven overnight to A. remove water B. purify the matrix C. remove carbon dioxide adn sulfer dioxide D. anneal the crystal structure She weighs 0.1553 g of dry potassium acid phthalate into a flask and adds some water from a graduated cylinder to dissolve it. Why doesn\'t she measure the volume of water with a more accurate device? A. The accuracy of the graduated cylinder is sufficient to measure to two decimal places which is all the precision needed for a titration. B. It would be better to measure the mass because it can be read to four decimal places with an analytical balance. C. The quantity of water actually is important and should be measured accurately because it affects the starting concentration thus the starting pH of the solution. D. The volume of water added is not important because the titration equivalence point depends only on the number of millimoles of potassium acid phthalate and not its concentration. The titration of 0.1553 g of dry potassium acid phthalate (MM = 204.227 g/mol) requires 49.84 mL of NaOH solution. What is the concentration of the NaOH solution? Why is freshly distilled or deionized water used in this standardization? A. Freashly distilled water contains no hydrogen peroxide B. Distilles water contains calcium, which stabilizes the sodium hydroxide C. Freashly deionized water has a pH of 4.72 D. There is little CO2 in freshly deionized or distilled water Which is a characteristic of a person with high self-esteem? a wide circle of friends feels worthy of love high academic achievement no drug or alcohol use According to the introduction, Mary Shelley wanted to write what type ofghost story?A.
