six friends are going to the state fair.The cost of one admission is $9.50, and the cost for one ride on the Ferris wheel is $1.
larisa86 [58]

We are given

total number of friends =6

the cost of one admission is $9.50

now, we can find total cost for admission

total cost for admission= total number of friends*cost of one admission

total cost for admission=6*9.50

we are given

cost for one ride on the Ferris wheel is $1.50

now, we can find total cost for Ferris wheel ride

total cost for Ferris wheel ride= total number of friends*cost of one ride

total cost for Ferris wheel ride=6*1.50

now, we can find total cost

total cost =total cost for admission+total cost for Ferris wheel ride

total cost=6*9.50+6*1.50

now, we can solve it

total cost=6(9.50+1.50)

total cost=6*11

total cost=66

so, the total cost is $66...........Answer

Your lumber company has bought a machine that automatically cuts lumber. The seller of the machine claims that the machine cuts
maksim [4K]

Answer:

a) 0.0202

b)The seller's claim is not correct.

c) If the seller's claim is true we cannot have individual length of 72.15 inch.

Step-by-step explanation:

In the question it is given that

population mean, μ = 72 inch

Population standard deviation, σ = 0.5 inch

Sample size, n = 47

Sample mean, x =72.15 inch

a) z score = \frac{x-\mu}{\sigma/\sqrtr{n}} = \frac{72.15-72}{0.5/\sqrt{47}} = 2.0567

P(x ≥ 72.15) = P(z ≥ 2.0567) = 0.5 - 0.4798 = 0.0202

We calculated the probability with the help of standard normal table.

b) The sellers claim that the machine cuts the lumber with a mean length of 72 inch is not correct as we obtained a very low probability.

c)If we assume that the seller's claim is true that is the machine cuts the lumber into mean length of 72 inch then we cannot have an individual length 72.15.

Standard error = \frac{\sigma}{\sqrt{n} } = 0.0729

Because it does not lie within the range of two standard errors that is (μ±2 standard error) = (71.8541,72.1458)

Which expression is equivalent to ^4 sqrt 144a^12 b^3
Alex_Xolod [135]
The expression equivalent to <span> ^4 sqrt 144a^12 b^3 will be found by simplifying our expression as follows:
</span><span> ^4 sqrt 144a^12 b^3
=(144a^12b^3)^(1/4)
=(12^2a^12b^3)^(1/4)
=12^(1/4*2)a^(12*1/4)b^(3*1/4)
=12^(1/2)a^3b^(3/4)

Answer: </span>12^(1/2)a^3b^(3/4)
