bonufazy [111]

Answer:

1 mile = 1,609 meters is the key to converting the rates of the two swimmers

Step-by-step explanation:

there are 60 seconds in a minute and 60 minutes in an hour

so 1.8 meters/sec x 60 sec/min x 60 min/hr = 6480 meters/hr

now we convert meters to miles

6480 meters/1 hr x 1 mile/1609 meters = roughly 4 miles/hr (4.027)

or we can convert the other rate to meters/sec

2.5 mi/hr x 1hr/60 min x 1min/60 sec = 0.00069444 mi/sec

then convert miles to meters

0.00069444 mi/sec x 1609meters/ 1mi = roughly 1.1 meters/sec (1.117)

Answer:

(4, - 6 )

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 270°

a point (x, y ) → (y, - x ) , thus

(6, 4 ) → (4, - 6 )

Complete parts (a) through (c) below.

nexus9112 [7]

Answer:

a) $t_{crit}=1.34$

b) $t_{crit}=-1.33$

c) $t_{crit}=\pm 2.11$

Step-by-step explanation:

Part a

$\alpha=0.1$ represent the significance level

df =15

Since is a right tailed test the critical value is given by:

$t_{crit}=1.34$

And we can use the following excel code to find it: "=T.INV(0.9,15)"

Part b

$\alpha=0.1$ represent the significance level

n=20 represent the sample size

First we need to find the degrees of freedom given by:

$df=n-1=20-1=19$

Since is a left tailed test the critical value is given by:

$t_{crit}=-1.33$

And we can use the following excel code to find it: "=T.INV(0.1,19)"

Part c

$\alpha=0.05$ represent the significance level

n=18 represent the sample size

First we need to find the degrees of freedom given by:

$df=n-1=18-1=17$

The value of $\alpha=0.05$ and $\alpha/2 =0.025$

Since is a two tailed tailed we have two critical values is given by:

$t_{crit}=\pm 2.11$

And we can use the following excel code to find it: "=T.INV(0.025,17)"
