A lot with a depth of 80 feet and an area of 4,800 square feet was sold for $350 per front foot. What was the total sales price?

stepladder [879]

Answer:

total sales price = $21,000

Step-by-step explanation:

given data

depth = 80 feet

area = 4,800 square feet

sold = $350 per front foot

to find out

total sales price

solution

first we get here front feet that is the front length of a parcel

front feet = $\frac{area}{depth}$ ...................1

front feet = $\frac{4800}{80}$

front feet = 60

so total sales price will be

total sales price = 60 × $350 per front foot

total sales price = $21,000

We wish to give a 90% confidence interval for the mean value of a normally distributed random variable. We obtain a simple rando

coldgirl [10]

Answer: $(9.27025,\ 11.12975)$

Step-by-step explanation:

Given : Sample size : n= 9

Degree of freedom = df =n-1 =8

Sample mean : $\overline{x}=10.2$

sample standard deviation : $s= 1.5$

Significance level ; $\alpha= 1-0.90=0.10$

Since population standard deviation is not given , so we use t- test.

Using t-distribution table , we have

Critical value = $t_{\alpha/2, df}=t_{0.05 , 8}=1.8595$

Confidence interval for the population mean :

$\overline{x}\pm t_{\alpha/2, df}\dfrac{s}{\sqrt{n}}$

90% confidence interval for the mean value will be :

$10.2\pm (1.8595)\dfrac{1.5}{\sqrt{9}}$

$10.2\pm (1.8595)\dfrac{1.5}{3}$

$10.2\pm (1.8595)(0.5)$

$10.2\pm (0.92975)$

$(10.2-0.92975,\ 10.2+0.92975)$

$(9.27025,\ 11.12975)$

Hence, the 90% confidence interval for the mean value= $(9.27025,\ 11.12975)$

Which function do you evaluate first in g(f(x))? f(x) g(x) f(g(x))

Mazyrski [523]

For the composite function g(f(x)), the function f(x) goes first in terms of evaluation. This is the inner most function. You would read it from right to left in terms of determining the order of evaluation.
