No you did not

If original function is y= 3x-2 than inverse function is

3x=y+2 => x= (y+2)/3 than when we change the roles

we get inverse function y=(x+2)/3

Good luck!!!

If an experimenter sets equal to .01, then she is defining a "statistically rare" event as an event occurring more than one time

Fynjy0 [20]

Answer:

The correct answer is an event occurring one or fewer times in 100 times if the null hypothesis is true.

Step-by-step explanation:

For a statistically rare event, its probability is relatively small and the event is very unlikely to occur. Therefore, if an experimental sets equal to 0.01 which is statistically rare, then we can interpret this mathematically as:

p(event) = 0.01 = 1/100

where p(event) is the probability of the event.

In addition, statistically, null hypothesis signifies no major difference between the specified parameters, and any obvious difference that might occur as a result of experimental error. Thus, it can be concluded that the event is occurring one or fewer times in 100 times if the null hypothesis is true.

Ben drove 230 kilometers in 3 hours, and Pia drove 250

Drupady [299]

9514 1404 393

Answer:

Pia drove faster

Step-by-step explanation:

Speed is the ratio of distance to time. If the time is the same, the greater distance is associated with the greater speed.

Pia drove farther in 3 hours, so drove faster.

Carla uses a compass and straightedge to construct perpendicular lines. Daryl uses technology to construct perpendicular lines.

pogonyaev

Answer:

Carla used human accuracy to create perpendicular lines.

-She will grab a pencil and a bond paper

-She will grab the straighthead and the compass.

-She will test with the compass if the straighthead is orientated correctly.

-She will now make a line with the correctly orientated straighthead and pencil.

-She has finished

Daryl, used technological ease to create perpendicular lines.

-He opens his PC

-He opens Microsoft Word™

-He will insert two lines, one orientated 0° ↑, and one orientated 90° →

-He now connects the two lines.

-He will print the file

-He has finished.

A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matc

swat32

Answer:

Step-by-step explanation:

Systolic. Calculate the mean

118+128+158+96+156+122+116+136+126+120+

=1276÷10 = 127.6.

To calculate the median arrange the values from the lowest to the highest.

96,116,118,120,122,126,128,136,156,158.

122+126+2=124.

Disastolic

80+76+74+52+90+88+58+64+72+82= 736÷10=73.6

To calculate the median arrange the values from the lowest to the highest.

52,58,64,72,74,76,80,82,88,90

Median= 74+76=150÷2=75.

Comparison

The Systolic and diastolic blood pressure measures different things, so comparing them is of no use.

It will be good if the relationship between the blood pressure can be investigated because the data are in pairs.
