Answer: 0.17</h3>
This is the probability that corresponds to x = -5, which is less than x = -3, and it's the only x value of the list smaller than -3. There's not much else to say about this.
If we wanted to find something like P(X < -2), then we would add up the probabilities for x = -5 and x = -3 to get 0.17+0.13 = 0.30
The surface area of the cone is given by:
SA=πrl
Thus the surface area of the cone will be:
SA=π×4×5
SA=20π=63.932
Surface area of the pyramid is given by:
SA=1/2×4×(b×l)
thus the base length will be:
63.932=10l
thus
l=6.3932 in
Answer:
What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000
To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000
Answer: Jim is <span>15 years old
Jim = 15 years old,
</span><span>Dad is 4 times as old as his son Jim = = 15 x 4 = 60
In 10 years, Jim = 15 + 10 =25 years old
Dad = 60 + 10 = 70
</span><span>Dad's age will be 20 years more than twice Jim's age
</span><span>
Dad's age = 20 + 2(25) = 70
</span>
