Answer:

50 pockets

Step-by-step explanation:

Given

Total = 75\ yd

Pocket = 1\frac{1}{2}yd

Required

Determine the number of pockets

To calculate the required , we make use of:

Pockets = \frac{75yd}{1\frac{1}{2}yd}}

Pockets = \frac{75}{1\frac{1}{2}}}

Convert the denominator to decimal

Pockets = \frac{75}{1.5}

Pockets = 50

<em>Hence, she can lace 50 minutes</em>

A new catalyst is being investigated for use in the production of a plastic chemical. Ten batches of the chemical are produced.
zzz [600]

Answer:

CI=(66.54,78.46)                                  

Step-by-step explanation:

Given : A new catalyst is being investigated for use in the production of a plastic chemical. Ten batches of the chemical are produced. The mean yield of the 10 batches is 72.5% and the standard deviation is 5.8%. Assume the yields are independent and approximately normally distributed.

To find : A 99% confidence interval for the mean yield when the new catalyst is used ?

Solution :

Let X be the yield of the batches.

We have given, n=10 , \bar{X}=72.5\% , s=5.8%

Since the size of the sample is small.

We will use the student's t statistic to construct a 995 confidence interval.

\bar X\pm t_{n-1,\frac{\alpha}{2}}\frac{s}{\sqrt n}

From the t-table with 9 degree of freedom for \frac{\alpha}{2}=0.005

t_{n-1,\frac{\alpha}{2}}=t_{9,0.005}

t_{n-1,\frac{\alpha}{2}}=3.250

The 99% confidence interval is given by,

CI=72.5 \pm 3.25\frac{5.8}{\sqrt{10}}

CI=72.5 \pm 5.96

CI=(72.5+5.96),(72.5-5.96)

CI=(66.54,78.46)

Nick had 3 1/4 bottles of water for his wrestling practice when he finished he had 124 bottles of water left he said he used to
Ostrovityanka [42]
Nick had 3 1/4 bottles before, and he had 1 2/4 bottles left, so that means
3 1/4 - 1 2/4 =  1.75
1.75= 1 3/4.
So, I do not agree with nick.

Hope this helps!!!   :)
