98 Points And Brainliest!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!A poll asked 15 men in two age groups, 30 and younger and older than 30, whether they had facial hair (mustache, beard, sideburns, etc.). The results are recorded in the table. Person Age group Facial hair 1 30 and younger Yes 2 30 and younger No 3 Older than 30 No 4 30 and younger No 5 Older than 30 No 6 Older than 30 Yes 7 Older than 30 Yes 8 Older than 30 No 9 30 and younger Yes 10 30 and younger Yes 11 Older than 30 Yes 12 30 and younger Yes 13 Older than 30 Yes 14 30 and younger No 15 Older than 30 Yes (a) Create a two-way table of the data. Of the men surveyed, how many were 30 and younger? How many men did not have facial hair? (b) Create a two-way relative frequency table that displays the relative frequency of the men 30 and younger and of the men older than 30 who had or did not have facial hair. Express your answers as decimals written to three decimal places. (c) What percentage of men older than 30 had facial hair?

(PLEASE HELP!!! BEST ANSWER GETS BRAINLIEST!!!Energy from the Sun and Earth's interior drives the cycling of materials, including the rocks and minerals. The physical and chemical changes that occur in Earth's materials is caused by this flow of energy and cycling of materials. This diagram shows the processes involved in the rock cycle. Depending on environmental and other factors, rocks can spend anywhere from 200,000 years to millions of years in any stage of the cycle. Based on this information and the diagram shown, which statement best describes the sequence of the rock cycle? A) Igneous rock changing to sedimentary rock takes the longest amount of time, because it must first become sediment. B) Because the steps occur in the same order and is continuous, scientists can accurately determine how long rocks take to change. C) Each type of rock has three different methods of changing into another, but melting and cementation take the least amount of time. D) Processes, like melting, crystallization, and weathering, act together to form rocks and minerals, but the rate of change varies.

45 POINTS For the month of June, a music supply company is promoting the launch of its electronic music club by offering new members two options for downloading music.Option #1: Annual club membership at a fee of $125 per year plus an option of prepaying for unlimited music downloads at a rate of $10 per month.Option #2: Annual club membership at a fee of $50 per year plus an option of prepaying for music downloads at a rate of $1 per song.You decide to join the electronic music club for one year, but aren’t sure which membership option is best suited for your music downloading needs. Review both options that the music supply company is offering for its new club members. Use the information provided to respond to the following prompts. When necessary, answer in complete sentences and include all calculations.Write a function that best models the total cost of club membership plus downloads under option #1.For membership option #1, calculate the total cost for one year of club membership and prepaid unlimited music downloads.Write a function that best models the total cost of club membership plus downloads under option #2Calculate the maximum number of music downloads that you will have with one year of club membership under option #2 for the same annual cost of a membership with unlimited downloads.Over the past year, you downloaded an average of 14 songs per month. Assuming that for the next year, you continue to download music at the same rate per month, which membership option is most cost effective?~Thank you

PLEASE HELP 94 POINTS (might take awhile but its worth it)1. A local pizzeria sold 65 pizzas yesterday. (a) The owner offers the employees a bonus if the number of pizzas sold increases by 20% today. How many total pizzas must the pizzeria sell for employees to receive the bonus? Explain your answer. (b) Suppose the actual number of pizzas sold was 60. Describe the number of pizzas sold as a percent increase or decrease as compared to the amount sold yesterday, rounded to the nearest tenth. Show your work.2. A certain TV can be purchased from the manufacturer for $160. A certain online retailer has a standard markup of 30%, and a certain superstore has a standard markup of 40%.(a) What is the price of the TV when purchased online? What is the price of the TV when purchased at the superstore?(b) What is the difference between the prices in Part (a)? What is the difference between the markups? How does the difference in price relate to the difference in the markups?3. You purchase a car using a $22,000 loan with a 4.5% simple interest rate. (a) Suppose you pay the loan off after 4 years.

Gina wrote the following paragraph to prove that the segment joining the midpoints of two sides of a triangle is parallel to the third side:Given: ΔABCProve: The midsegment between sides Line segment AB and Line segment BC is parallel to side Line segment AC.Draw ΔABC on the coordinate plane with point A at the origin (0, 0). Let point B have the ordered pair (x1, y1) and locate point C on the x-axis at (x2, 0). Point D is the midpoint of Line segment AB with coordinates at Ordered pair the quantity 0 plus x sub 1, divided by 2. The quantity 0 plus y sub 1, divided by 2 by the slope formula. Point E is the midpoint of Line segment BC with an ordered pair of Ordered pair the quantity of x sub 1 plus x sub 2 divided by 2. The quantity of 0 plus y sub 1 divided by 2 by the slope formula. The slope of Line segment DE is found to be 0 through the application of the slope formula: The difference of y sub 2 and y sub 1, divided by the difference of x sub 2 and x sub 1 is equal to the difference of the quantity 0 plus y sub 1, divided by 2, and the quantity 0 plus y sub 1, divided by 2, divided by the difference of the quantity x sub 1 plus x sub 2, divided by 2 and the quantity 0 plus x sub 1, divided by 2 is equal to 0 divided by the quantity x sub 2 divided by 2 is equal to 0 When the slope formula is applied to Line segment AC the difference between y sub 2 and y sub 1, divided by the difference of x sub 2 and x sub 1 is equal to the difference of 0 and 0, divided by the difference of x sub 2 and 0 is equal to 0 divided by x sub 2 is equal to 0, its slope is also 0. Since the slope of Line segment DE and Line segment AC are identical, Line segment DE and Line segment AC are parallel by the definition of parallel lines.Which statement corrects the flaw in Gina's proof?
