D: x ≥ 0
7 < √x < 8 ⇒ 7² < x < 8² ⇒ 49 < x < 64
Answer: x = 50 or x = 51 or x = 52 or ... or x = 63.

Step-by-step explanation: A Null Hypothesis is a hypothesis used in statistics to show that there is no variation among the variables of interest. A Null Hypothesis also can be said to be giving a proposal that there is not significant difference between the observed data.

Answer:
17 pants and 9 shirts
Step-by-step explanation:
questions like this require you to guess numbers first then adjust them as needed. I originally guessed 20 pants and 6 shirts, however the number was too high, so I put less pants, since they're the higher number. if the number was too low you would use less shirts since they're the lower number. after a couple of tries you'll get
(225 × 17) + (125 × 9) = 4950
but seriously who spends almost 5000 dollars on clothes from one store in one outing, that's so much money
Answer:
(3x-1) + (3x-1) + (2x+1) = 55
Step-by-step explanation:
1. 3x + 3x + 2x = 8x
2. -1 + -1 + 1 = -1
3. 8x -1 = 55
4. 8x = 55 + 1
5. 8x = 56/8
6. x = 7
