Is d but i’m no really sure:(
Answer:
0.8%
Step-by-step explanation:
Because they are two independent events, the final probability is the product of the probability of each event.
First event:
The complement of a student being male is that he is female.
Therefore, if 60% is male, the remaining 100% is 40%, meaning that 40% of the students are female.
Second event:
If she's taller than 5'4", we're told she has a 2% chance of being a woman.
Therefore the final probability is:
0.4*0.02 = 0.008
That is, the probability that it is female and that it is over 1.6 meters tall is 0.8%.
To solve this problem, we are going to set up a system of equations, or two equations that we can use to find out two variables. Let x represent the measure of one of the side lengths, and b represent the length of the base.
We know that the sum of the two equal legs is six more than three times the length of the length of the base, or the following equation.
2x = 6 + 3b
We also know that the perimeter, or the addition of both equal side lengths and the base equals 38, or the following equation.
2x + b = 38
To solve this system of equations, we can use substitution for 2x. (This means that because we know what 2x equals in terms of b, we can substitute this value into the other equation).
6 + 3b + b = 38
Now, we have to simplify and solve this equation.
4b + 6 = 38
4b = 32
b = 8
This means that the base measures 8 cm. Because we know this measurement, we can substitute 8 into one of our beginning equations for b to solve for x.
2x + b = 38
2x + 8 = 38
2x = 30
x = 15
Therefore, the base of the triangle is 8 cm, and the equivalent side lengths both measure 15 cm.

Hope this helps!
X=16 because the the small triangle you just multiply the big triangle by 4
