Can someone tell me if my answer to this problem is correct, please? And if it isn't how do you solve it? ​
Mrac [35]

Answer:

Height of tree= 13.8m

Step-by-step explanation:

When finding the value of a in your working, I suggest to leave the answer to 5 significant figures so that your final answer is more accurate. The value of a should be 26.048m to 5 s.f.

Then multiplying 26.048 with sin 32° would give you 13.8m too when rounded off to 3 significant figures :)

I have attached my working too.

HELP NEEDED !!!!
Fofino [41]
The answer is Letter D - 84%

68% of the data is within +/- 1 SD from the mean = 59 to 7195% of the data is within +/- 2 SDs from the mean = 53 to 7799.7% of the data is within +/- 3 SDs from the mean = 47 to 83

The whole 68% (59 - 71) scored below 71. Since the data are evenly distributed, we'll get the 32% (100 - 68) outside the range of 68% and divide it by 2 and add the quotient to the original 68% so that we'll get the total data below 71.
   100 - 68 = 32
   32 / 2 = 16
   16 + 68 = 84

I really need help with this please ! I don't understand it, and I have a quiz tomorrow
erik [133]
You can do this by finding a number close to it, and then finding out how to do it.

For example with 63(square root sign), find out what is close to it.

7x7=49 while 8x8=64

Because of this, we now know that it is between 7 and 8 but is also really close to 8.

Our number could be 7.9

Hope this helped!!!
