A marketing firm would like to test-market the name of a new energy drink targeted at 18- to 29-year-olds via social media. Suppose a study found that 36% of adults (18 and older) do not use social media. Suppose the percentage of adults age 30 and older is 75%. Suppose that the percentage of the adult population that is either age 18–29 or uses social media is 66.7%. (a) What is the probability that a randomly selected adult uses social media?

Adam and Ian go to the movie theater and purchase refreshments for their friends. Adam spends a total of $62.75 on 2 drinks and 7 bags of popcorn. Ian spends a total of $43.00 on 4 drinks and 4 bags of popcorn. Write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn. Using these equations, determine and state the price of a drink, to the nearest cent.

Adjusting the probability statement P(35.5 ≤ x ≤ 39.5) to the standard normal variable resulted in P(1.59 ≤ z ≤ 2.74). Recall that the normal probability table gives area under the curve to the left of a given z value. Use the table to find P(1.59 ≤ z ≤ 2.74), the probability that between 36 and 39 questions are answered correctly, rounding the result to four decimal places. P(1.59 ≤ z ≤ 2.74) = P(z ≤ 2.74) − P(z ≤ 1.59)

Using traditional methods it takes 9898 hours to receive an advanced flying license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 100 students and observed that they had a mean of 97 hours. Assume the population variance is known to be 49. 1. Is there evidence at the 0.05 level that the technique performs differently than the traditional method? 2. Find the value of the test statistic. Round your answer to two decimal places.

A taxi company charges passengers $2.00 for aride, and an additional $0.50 for each miletraveled. The function rule c = 0.50m + 2.00describes the relationship between the numberof miles m and the total cost of the ride C. If thetaxi company will only go a maximum of 40miles, what is a reasonable graph of thefunction rule?

One day, Frankie and Gia each bought a new camera. The equation f(x)=320(0.85)^x represents the value of Frankie’s camera, in dollars, x years later. The table shows the value of Gia’s camera x years later.Select from the drop-down menus to complete the statement.When they made their purchases, (Frankie's or Gia's) camera was worth ($3, $24.50, $45, or $72.50) more than (Frankie's or Gia's) camera.Plz hurry!!

LAST ONE I SWEAR BUT STILL WILL MARK BRAINLIEST Choose a system of equations with the same solution as the following system:6x + 2y = −63x − 4y = −18a. 8x + 4y = −417x + 2y = −28b. 12x + 4y = 1221x + 2y = −36c. 6x + 8y = −3615x + 6y = −60d. 6x + y = 1515x − y = −9
