Answer:
Erin
Step-by-step explanation:
Z score formula:
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For Candice:
Z score = 74 -66/4
Z score = 2
For Erin
Z score = 58 - 42/7
Z score = 2.28571
Erin z score is larger hence, he did better
Answer:
Assuming it would be -x-4
Answer:
(x + 2)² + (y + 7)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
Here (h, k) = (- 2, - 7) and r = 3, thus
(x - (- 2))² + (y - (- 7))² = 3², that is
(x + 2)² + (y + 7)² = 9
Answer:
400
Step-by-step explanation:
because if u look sideways it shows just one step up and it's 400 or it can be 500 to get 9:45
19 does not divide evenly into 491; there will be a remainder.
491
------- = 25.84, or 25 16/19
19
