To do this you need 94 inches of braid.
<span>94 inches = 2.61 yards
You would need to buy 3 yards so:
$0.60 </span>× 3 = $1.80.
Since you bought 3 yards that would cost $1.80.

In this question we simple wish to calculate the standard error and margin of error from the population. This can be done purely using the standard deviation and sample size.
Standard error
= std dev / (SQRT) n
= 11.5 / SQRT of 70
= 11.5 / 8.366
= 1.374
Margin of error is the standard error multiplied by a Z value that correspondence to a confidence percentage. At a 95% confidence the Z value is 1.96. Therefore
MOE = 1.96 x 1.374 = 2.69

Answer:
Step-by-step explanation:
y varies directly as x
It means y=kx
y=18 when x=5
y=kx
18=k5
k=18/5
y=? When x=11
y=ky
Substitute the value of k
y=18/5(11)
=18×11/5
=198/5
=39.5
