Step-by-step explanation:

A study was to be undertaken to determine if a particular training program would improve physical fitness. A sample of 31 university students was selected to be enrolled in the fitness program. The researchers wished to determine if there was evidence that their sample of students differed from the general population of untrained subjects. The sample mean is 47.4 and a standard deviation of 5.3. The 98% confidence interval is determined and is given as, (45.2, 49.6) .

If the level of confidence is changed to 95%, then the confidence interval will become shorter but the p-value will not change because it is calculated using the test statistic. So the correct answer is (a).

azamat

Answer:

68.17m

Step-by-step explanation:

Please see attached a rough sketch of the scenario

Step one:

Given data

Height of victim= 4.5ft

The horizontal distance of the snipper from the building = 780ft

The angle of elevation= 5 degrees

Required

The vertical distance

The opposite= the vertical distance

789 ft = the adjacent

Step two:

Applying SOH CAH TOA

tan ∅= opp/adj

tan 5= opp/780

cross multiply we have

0.0874= opp/780

cross multiply we have

0.0874*780= opp

opp= 68.17m

The sniper shoots from a vertical distance of  68.17m

HELPPPPP!!!! 20 POINTS GIVEN!
babunello [35]

Answer:

Answer

4.0/5

20

JannetPalos

While representing 3 - 4 on the number line, from the starting point 0, we need to show an arrow to three numbers on the right.

Since - 4 is the additive inverse of 4, from the point where the first arrow pointed, we should go 4 points to the left.

Hence, the number line which shows an arrow from 0 to 3, and then from 3 to negative 1 is the correct one.

Step-by-step explanation:

Hope that helps!!
