Evaluate f-2g for f = 4 and g = 32. 2 8

Basile [38]

Subsitute the equation first. F- 2g is also 4-2(32). Then you do pemdas and since multiplication is first you do 2 x 32 and get 64. Then you subtract 4 and 64 to get -60

A circle measure 12 feet in diameter what’s its area to the nearest foot

kipiarov [429]

The formulas for the circumference and area of a circle are

$C = 2\pi r,\quad A = \pi r^2$

So, if we isolate the radius from the formula for the circumference we have

$r = \dfrac{C}{2\pi}$

And if we substitute this expression for the radius in the formula for the area, we have

$A = \pi r^2 = \pi \dfrac{C^2}{4\pi^2} = \dfrac{C^2}{4\pi}$

So, if you plug your value you have

$A = \dfrac{144}{4\pi} = 11.4591559\ldots \approx 11$

A data set includes 109 body temperatures of healthy adult humans for which x overbarxequals=98.2°F and s equals 0.62 degrees Up

seraphim [82]

Answer:

Step-by-step explanation:

Given that a data set includes 109 body temperatures of healthy adult humans for which sample mean =98.2°F and s equals 0.62 degrees

Std error of mean = $\frac{s}{\sqrt{n} } \\=0.0594\\$

df = 108

Critical value for 99% t =2.581

Margin of error = 2.581*std error = 0.1533

99% confidence interval = Mean ±0.1533

= $(98.0467, 98.3533)$

a) Since the confidence interval does not contain 98.6 degrees we reject the null hypothesis that mean = 98.6 degrees

b) confidence interval for population mean = 98.6±0.1533

= $(98.4467, 98.7533)$
