Answer: x = (1,9]
Step-by-step explanation: If x is all real numbers greater than 1 (simply: x is greater but not equal to 1) then it is 1 < x. And if x is less than or equal to 9 then its x ≤ 9. To translate 1 < x ≤ 9 into interval notation, you need to keep in mind that parentheses are for these symbols: <>. And brackets are for these symbols: ≤≥. With that in mind, your answer is (1,9]. Also, keep in mind that interval notation goes from lowest value number to highest, so you wouldn’t write this notation as [9,1).
Answer:
hence Robert runs at a faster speed
Step-by-step explanation:
1 1/2 hours = 3/2 hours = 1.5 hours
45 min = 45/60 = 3/4 = 0.75 hours
Jacob's speed = 5 miles ÷ 1.5 hours = 3.33 miles/hr
Robert's speed = 3 miles ÷ 0.75 hours = 4 miles/hr
hence Robert runs at a faster speed
Pick any 2 data points from the list, say (6,13) and (5,11)
compute m, slope using the slope fornula m= y2-y1/x2-x1 = 13-11/6-5=2/1=2. pick any point and write your equation in slope intercept form
y-11=2(x-5)
y-11=2x-10
y=2x+1. answer B
Answer:
65
Step-by-step explanation:
Next year, there will be 3.5% fewer, so 100% - 3.5% = 0.965 times the number present this year. This same multiplication is repeated each year.
After 6 years, the number present will be 0.965^6 times the number this year, or ...
80 × 0.965^6 ≈ 80 × 0.80754 ≈ 64.60
There will be about 65 animals after 6 years.
