Answer:these weren’t all right
Step-by-step explanation:
The theoretical probability of getting heads or tails is 1/2 the time.
1/2 of 150 = 75
So theoretically you would get 75 heads and 75 tails.
The experiment got 84 heads, which is greater than 75, so it would be higher than the theoretical probability.
The answer is : <span>It is 6% higher than the theoretical probability.</span>
Answer:220
Step-by-step explanation:
LET X BE THE LENGTH OF RECTANGLE AND FOR UPPER PORTION OF DIA GRAM BASE OF RIGHT ANGLE TRIANGLE SO X=20
LET Y BE WIDTH OF RECTANGLE SO Y=8
LET P BE THE PERPENDICULAR OF THE RIGHT TRIANGLE SO P=6
THEN
AREA OF RECTANGLE=LENGTH*WIDTH
SO AREA OF RECTANGLE BECOMES=(20)(8)=160
AND AREA OF RIGHT ANGLE TRIANGLE BECOMES=1/2(BASE*(PERPENDICULAR)
SO =1/2(20)(6)=60
SO THE TOTAL AREA OF THE DIAGRAM=AREA OF RIGHT ANGLE TRIANGLE+AREA OF RECTANGLE=160+60=220
So we can set up a right triangle in this situation with one of the legs being 21.4m and the height being 15m. Then we can use trigonometric formulas to find the angle of elevation of the sun.
Since we have the dimensions for the opposite and the adjacent sides, we can use the trigonometric function tangent to find the angle:

So let's plug this in:



However this is in radians - to convert to degrees, we must use the formula:

So then let's solve for degrees:



So now we know that the angle of elevation is 67.89°.
