22. (09.06) Megan claims that her horse can do simple addition problems. She showed her horse 8 different cards with simple addition problems, and the horse was able to tap his foot to indicate whether the answer
was correct or incorrect. The horse correctly identified all 8 cards. Rob didn't believe Megan's horse could do addition, so he set up a trial to test whether the horse was just guessing. He flipped 8 coins to
see how many would land talls up. He did this 53 times, and the results are shown in the dot plot below:
Based on these results, can Megan's horse add? (1 point)
O No, the chances of getting 8 correct by guessing are very low
Yes, the chances of getting 8 correct by guessing are very low
Yes, the horse is likely to get them all correct
No, horses can't add

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
