Answer:

in a triangle,

G+E+F = 180°

or, 24°+17°+F = 180°

or, 41°+F = 180°

or, F= 180-41

F = 139°

A manager records the repair cost for 14 randomly selected dryers. A sample mean of $88.34 and standard deviation of $19.22 are

s2008m [1.1K]

Answer:

Hence the 90% confidence interval estimate of the population mean is $(79.24 , 97.44)$

Step-by-step explanation:

Given that,

Point estimate = sample mean = $\bar x$ = 88.34

sample standard deviation = s = 19.22

sample size = n = 14

Degrees of freedom = df = n - 1 = 13

Critical value = $t\alpha /2,$ df = 1.771

Margin of error

$E = t\alpha/2,df \times (\frac{s}{\sqrt{n} } )\\= 1.771 \times (19.22 / \sqrt 14)$

Margin of error = E = 9.10

The 90% confidence interval estimate of the population mean is,

$\bar x - E < \mu < \bar x + E\\\\88.34 - 9.10 < \mu < 88.34 + 9.10\\\\79.24 < \mu < 97.44\\(79.24 , 97.44)$

Luisa earns money mowing her neighbors' lawns.

Irina-Kira [14]

Answer:

$p(x)=16x-25$

C is the correct option.

Step-by-step explanation:

We have been given that

$r(x)=20x\\c(x)=4x+25$

The profit is the difference of revenue and cost function.

Mathematically, we can write profit function as

$p(x)=(r-c)x$

We know that $(f-g)(x)=f(x)-g(x)$ . Thus, we have

$p(x)=r(x)-c(x)$

Plugging, the r(x) and c(x) functions

$p(x)=20x-(4x+25)$

Distribute negative over the parenthesis

$p(x)=20x-4x-25$

Combine the like terms. 20x-4x = 16x

$p(x)=16x-25$

C is the correct option.

If you’re trying to find how much more a RN makes compared to a dietitian, it would be 10,746. To find this, take the two salary’s and subtract. 64,690-53,944 = 10,746.
