The valence of a song is measured from 0 to 10 and detects the musical positiveness conveyed in the song. Tracks with high valence sound more positive (e.g. happy, ch with low valence sound more negative (e.g. sad, depressed, angry). The valence was computed for 42,000 songs on Spotify in the genres of Techno, Techhouse, Trance, Trap, Psytrance, DnB, Hardstyle, Underground Rap, Trap Metal, Emo The table below shows the number of songs with a given valence measurement.

In a recent survey, a magazine reported that the preferred room temperature in the summer is 68°F. A wall thermostat, like the ones shown below, tells a room's temperature in degrees Fahrenheit Sarah's Upstairs Bedroom Downstairs Bedroom 72°F 64°F a. Which bedroom is warmer than the recommended room temperature? b. Which bedroom is cooler than the recommended room temperature? c. Sarah notices that her room's temperature is 4°F above the recommended temperature, and the downstairs bedroom's temperature is 4°F below the recommended temperature. She graphs 72 and 64 on a vertical number line and determines they are opposites. Is Sarah correct? Explain. d. After determining the relationship between the temperatures, Sarah now decides to represent 72°F as 4 and 64°F as -4 and graphs them on a vertical number line. Graph 4 and -4 on the vertical number line on the right. Explain what zero represents in this situation. EUREKA MATH Lesson 4: The Opposite of a Number O 2019 Great Minds.…
