Answer:
63,360 feet
Step-by-step explanation:
1 mile = 5280 ft
* 12 *12 (multiply 12 to both sides)
------------------
12 miles = 63,360 ft
3 x^3 y^2
_______
8 ( y/x-3/2)
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).
Answer:
Step-by-step explanation:
Given are two triangles ABC and XYZ.
We have AB = XY = 25 cm, AC = YZ = 29 cm
and also angle A = angle X = 36 degrees
Thus we find that corresponding congruent sides are
AB and AC with angles A and X
To map ABC onto xyz,
Vertex B to Y, side AB to side XY with AC coinciding with XZ
Now all vertices x,y,z will perfectly match with transformed ABC
