Answer:
-3,-6? im not sure what you're asking
Step-by-step explanation:
Using the coordinate plane, if you move 4 units to the left of 1 you get -3, moving it down 5 you get -6 then plug them in to the ordered pair (x,y) so (-3,-6)
For a 95% confidence interval, the corresponding z-score is 1.96. Therefore the deviation will by 1.96*0.5 lbs = 0.98 lbs. Therefore, the confidence interval will be (5 - 0.98, 5 + 0.98), which is (4.02, 5.98). The weight range is from 4.02 lbs to 5.98 lbs.
Answer:
X=125/64
Step-by-step explanation:
x^2+4 x-5=0
x^2+4x=5
4x^3=5
x^3=5/4
x=5^3/4^3
x=125/64
4(1/2x7)=12 <=> x28/2=12
x=12*2/28=24/28=12/14=6/7
