GalinKa [24]

Answer: 0.80

Step-by-step explanation:

Given : The owner of the West End Kwick Fill Gas Station wishes to determine the proportion of customers who pay at the pump using a credit card or debit card.

He surveys 100 customers and finds that 80 paid at the pump.

Then, sample proportion= $\dfrac{80}{100}=0.80$

Since , the best point estimate for population proportion is sample proportion.

Therefore, the estimated value for population proportion =0.80

What is the simplified value of the exponential expression 16^1\4

Natalka [10]

If you observe that $16 = 2^4$ , you can rewrite the expression as

$16^{\frac{1}{4}} = (2^4)^{\frac{1}{4}}$

Now, if you use the exponent rule $(a^b)^c = a^{bc}$ , you may rewrite the expression again:

$(2^4)^{\frac{1}{4}} = 2^{4\cdot\frac{1}{4}} = 2^1 = 2$

The distance traveled varies directly with the time spent in motion when speed is held constant.

disa [49]

Answer:

16/3 or 5.3

Step-by-step explanation:

150 miles = 4 hours

Find how long it takes to travel 50 miles(GCF between 150 and 200)

150/3 = 4/3

50 miles = 1 1/3 hours: multiply by 4 to get 200 miles

50 x 4 = 4/3 x 4/1

200 = 16/3

16/3 hours or 5.3
