Answer: -1/9 which is <u>choice B</u>
Explanation:
The term "zeros" refers to the x intercepts.
Plug in y = 0 and solve for x.
y = -9x-1
0 = -9x - 1
9x = -1
x = -1/9
Two and four will work. Just plug in the numbers to see

Mean : m = 2.2
Standard deviation: s = 0.3
m - 1 s = 2.2 - 0.3 = 1.9
m + 1 s = 2.2 + 0.3 = 2.5
For the normal distribution the values less than 1 standard deviation away from the mean account for 68.27 % of the set.
Answer: D ) 68 %
Answer:
$38.50
Step-by-step explanation:
We are told the cost of the fabric per meter, so we first need to convert 250 cm into meters.
1 meter = 100 cm
Therefore, 250 cm = 250 ÷ 100 = 2.5 meters
cost of fabric = $15.40 per meter
To calculate the total cost, mulitply the length in meters by 15.40:
2.5 x 15.40 = 38.50
