1. i think Choice A.(Unsure of this one, it’s between choices A & C)
2. t=19
3. I think Choice C
44. You can come to this answer by using algebra,
1/2x = 22
Multiply both sides by 2(denominator) thus,
X = 44.
Or you can use lateral thinking and realise that if 22 is 50%, you need to multiply by 2 to reach 100%.
C(-4;3)
D(1:0)
Image the right triangle between C, D and the point A(-4,0)
CA is 3-0=3; AD is 1-(-4)=1+4=5
CD is √3²+5²=√34=5.8309...
Answer:
x^2 = 22.99
Step-by-step explanation:
Given data:
standard deviation of all filled bottles = 0.1
