I can only help you with A and B....
hope it provides you a little help:)
Step-by-step explanation:
we know that on a 30 60 90 trianlge the length of the side opposite the 30 degree angle is half of the length of hypotenuse.So in this problem
the length of the side opposite the 30 angle is 17/2
talking about exercise on the photo the answer is
8√3 because it is given that the length of the side opposite the 30 anlge is 8 so hypotenuse is 16 we mentioned why before.
Now lets use pythagorean theorem
x^2+y^2=z^2
z is hypotenuse
8^2+y^2=16^2
64+y^2=256
y^2=256-64
y^2=192
y=8√3
Answer:
Either x = 2 or y = 6, depending on the original line
Step-by-step explanation:
So, if the original line is horizontal, our new line is vertical, and all vertical lines in a graph is x = some number. To pass through the point (2, 6), x has to equal 2, since the point's x-coordinate is 2.
On the other hand, if the original line is vertical, our new line is horizontal, which is y = some number. Our point's y-coordinate is 6, so our line should be that y = 6.
Well, you do the area of each individual side and add them together. The triangles have an area 108 square inches. The two 15 inch sides each have an area of 300 square inches each. And the bottom face has an area of 480 inches squared. You add them all together to get= 108+108+300+300+480, which is equal to 1,296 square inches.
Answer:
0.5818
Step-by-step explanation:
Suppose the average teenage romantic relationship is normally distributed with a mean number of 100 days with a standard deviation of 30 days.
Answer:
The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if it is negative then it is below the mean. It is given by:
Given that:
Therefore, from the normal distribution table, P(90 < x < 150) = P(-0.33 < z < 1.67) = P(z < 1.67) - P(z < -0.33) = 0.9525 - 0.3707 = 0.5818
