A spinner is divided into nine equal sections numbered 1 through 9. Predict how many times out of 270 spins the spinner is most
likely to stop on an odd number. Question 1 options: 70 150 200 240 Rowan has a bag containing 20 marbles. The table below shows the number of marbles of each color in the bag. As part of a probability experiment for his math class, Rowan randomly picks a marble from the bag and then replaces it. He repeats this 200 times. Predict the number of times out of 200 Rowan will pick a blue marble.

Question 3 options: 1/21 17/21 1/50 21/50 Save Question 4 (3 points) Question 4 Unsaved Which event has a probability of one? Question 4 options: Choosing a letter from the alphabet that is a vowel Choosing a number that is greater than one and is even Choosing a set of parallel lines on a polygon Choosing a square that is also a rectangle Save Question 5 (3 points) Question 5 Unsaved A six-sided number cube has faces with the numbers 1 through 6 marked on it. What is the probability that a number less than 2 will occur on one toss of the number cube? Question 5 options: 1/6 2/6 3/6 4/6 Save Question 6 (3 points) Question 6 Unsaved A set of five quadrilaterals consists of a square, a rhombus, a rectangle, a trapezoid, and a parallelogram. Sally selects one of these figures at random. What is the probability that only one pair of the figure’s opposite sides are parallel? Question 6 options: 1/5 3/5 4/5 2/5 Save Question 7 (3 points) Question 7 Saved Maelee’s Book Store has received a shipment of books. The table below shows the number of each type of book in the shipment. Maelee selects a book at random from the shipment. What is the probability that she chooses a children’s picture book? Question 7 options: 1/4 1/9 9/30 9/21 Save Question 8 (3 points) Question 8 Unsaved The faces of a cube are numbered from 1 to 6. If the cube is rolled once, which outcome is most likely to occur? Question 8 options: rolling an odd number rolling an even number rolling a number less than 4 rolling a number greater than 1 Save Question 9 (3 points) Question 9 Unsaved The spinner below is divided into twelve equal regions and is spun once. What is the probability of not getting red? Question 9 options: 1/12 6/12 7/12 5/12 Save Question 10 (3 points) Question 10 Unsaved Based on Robert’s baseball statistics, the probability that he will get a hit is 3/4. If Robert is at bat 40 times, how many times will he most likely get a hit? Question 10 options: 12 30 34 38 Save Question 11 (3 points) Question 11 Unsaved Buzz spins the arrow on a spinner with 5 equal sections labeled A, B, C, D, and E. Then, he rolls a 6-sided number cube with sides numbered 1 through 6. What is the probability that the arrow will stop on the letter D and the number cube will show an even number? Question 11 options: 1/11 4/6 3/30 4/30 Save Question 12 (3 points) Question 12 Unsaved A bag contains 60 marbles. The marbles are described below. There are exactly 10 yellow marbles in the bag. Of the marbles in the bag, 1/5 are red. Of the marbles in the bag, 20% are green. The rest of the marbles in the bag are blue. A marble is selected at random from the bag. Which outcome is most likely? Question 12 options: A blue marble is selected. A red marble is selected. A green marble is selected. A yellow marble is selected.\
In this case, there are ten boys and fourteen girls in this class. The ration would then be 10:14. Instead, Jeff said 5:12 which isn't correct. He can correct it by using the number of boys given, find the difference of girls in a class of twenty-four students, and then get his answer!
The bottom two because they rapidly go up or down super fast. If it’s an exponential function, it will start off as super low or super high and then shoot up or down rapidly
The cost of 1 vanilla ice cream and 1 strawberry ice cream should total to $31. Since you only bought one of each flavor, you simply have to add their unit prices.
Cost for 1 carton of strawberry ice cream + Cost for 1 carton of vanilla ice cream = Total Cost Total Cost = s + v --> this is the general equation
Since s = 1.5 + v, the modified equation would be Total Cost = 1.5 + v + v Total Cost = 1.5 + 2v
