Starting salaries of 90 college graduates who have taken a statistics course have a mean of $43,993 and a standard deviation of

inysia [295]

Answer:

a) E = 2482.90

b) 99% Confidence interval: (41510.1,46475.9)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ =$43,993

Sample size, n = 90

Alpha, α = 0.051

Sample standard deviation, s = $9,144

a) The margin of error

Formula:

$z_{critical}\text{ at}~\alpha_{0.01} = 2.576$

$E =z_{critical}\times \displaystyle\frac{s}{\sqrt{n}}\\\\E = 2.576\times \frac{9144}{\sqrt{90}}\\\\E = 2482.90$

b) 99% Confidence interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$43993 \pm 2482.90 = (41510.1,46475.9)$

A carpenter builds a rectangular bookcase that is 120 cm long and 62 cm tall. The carpenter uses two braces along the diagonals

Colt1911 [192]

Answer:

$135cm$

Step-by-step explanation:

We can use pythagoras' theorem to solve this.

$a^{2} +b^{2} =c^{2}$

let a be the long of the rectangle: a=120 cm

let b be the tall of the rectangle: b=62 cm

and c be the diagonal c=?

$a^{2} +b^{2} =c^{2}\\120^{2} +62^{2} =c^{2} \\c^{2} =14400+3844\\c^{2} =18244\\c=\sqrt{18244}\\c=135cm$

the length of the diagonal is 135cm

A vending machine sells chips at $0.40 and candy at $0.50. Last month, the vending machine yielded $139.80 with a sale of 298 it

Sidana [21]

Let us say... . the machine sold packages of chips at the amount of "p",
and the machine also sold, last month as well, an amount of "c" candies

now, last month the machine sold total 298 items
that yielded a revenue of $139.80

so...whatever "p" and "c" are, we know that, their sum for last month is,
298, so,
p + c = 298

how much revenue in sales of chips? well, they're 0.40 per package,
so, whatever "p" is, the machine sold 0.40 * p or 0.4p in revenue

how much for the candies? well, they're 0.50 for each, so
whatever "c" is, 0.50 * c or 0.5c in revenue

we know, their total revenue yield was 139.80
so
0.4p + 0.5c = 139.8

now... do substitution from the 1st equation on the 2nd one, and solve for "p", or packages of chips

that is $\begin{cases}
p+c=298\to c=\boxed{298-p}
\\ \quad \\
0.4p+0.5c=139.8
\\
\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\
0.4p+0.5(\boxed{298-p})=139.8

\end{cases}\impliedby \textit{solve for "p"}$
