Answer:
A. AB
Step-by-step explanation:
Given that the musical instrument has a shape of ∆ABC, we can determine the shortest side that would be parallel to the ground by comparison of the 3 angles of the triangle corresponding to each side that is opposite each of them.
What this means is that, the larger angle would have the largest side opposite it. The medium angle will have medium length side opposite it, while the smallest angle will have the smallest side opposite it.
m < A = 59°
m < C = 57°
m < C = 180 - (59+57) (sum of angles in a triangle)
m < C = 64°
The smallest angle out of the three angles is angle C = 57°.
The side opposite it, is side AB.
Side AB is the shortest side of ∆ABC.
Therefore, AB should be parallel to the ground.
Answer:
perimeter is sum of all four sides; two of which are '4j' and other two are 60 inches each
Step-by-step explanation:
P= 2(4j) + 2(60)
We know perimeter is 400 inches
400 = 8j + 120
8j = 280
j = 35
Answer:
C
Step-by-step explanation:
When you have an number with an exponent raised to an exponent, multiply the two exponents.
3*2=6
so the answer is (-8)^6
Question;
In the next year, an economist in a particular nation believes that exports will have a mean of 295 and a standard deviation of 12 (in millions of dollars). In addition, he believes that imports will have a mean of 70 and a standard deviation of 14 (in millions of dollars). Finally, he believes that the correlation between imports and exports will be -0.63. Define the trade balance as exports minus imports. Find the mean and the standard deviation of the trade balance (in millions of dollars) ROUND YOUR ANSWERS TO TWO DECIMAL PLACES
Answer:
Mean = mean exports - mean imports = 295 - 70 = 225.00
Standard deviation = 12 - 14 = -2( in million dollars)
