Answer:
$179.76
Step-by-step explanation:
We can calculate the total cost as follows. The 1.00 represents the before-tax cost of the dehumidifier and the 0.0575 the 5.75% sales tax:
Total cost of dehumidifier = (1.00+0.0575)($169.99) = $179.76 (to the nearest

17 ft=17x12=204 inches
204/18=11.333...
So you can cut 11 logs

Step-by-step explanation:
The proportion of defective corks produced by this machine through z test comes out is 0.320.
Given mean of 2 cm and standard deviation of 0.1 cm, The diameter is between 1.9 and 2.1 cm.
We have to find the proportion of defective corks that are produced by machine.
In this problem we have to first find z score and then we will be able to find the probability of defective corks produced by the machine.
Z=(X-μ)/σ
μ=2 cm and σ=0.1 cm.
Z value corresponding to X=1.9.
Z=(1.9-2)/0.1
=-0.1/0.1
=-1
Z value corresponding to X=2.1.
Z=(2.1-2)/0.1
=0.1/0.1
=1
P value of P(-1<Z<1)=2*0.3410=0.6820
Proportion of corks which are not defective=0.6820.
Proportion of corks which are defective=1-0.680.
=0.320
Hence the proportion of defective corks produced by machine is 0.320.
