Answer:
Q+D = 65, multiply both sides by 2525Q + 25D = 162525Q + 10D = 950 subtract to get 15D = 675 D = 675/15 = 135/3 = 45 dimes Q = 65-45 = 20 quarters25(20) + 10(45) = 500+450 = 950
I may not be correct but I think there will be about 62 dishes of both

Answer:
Option B
Step-by-step explanation:
<u>Option A
</u>
In order to make a triangle: a + b > c and b + c > a and c + a > b
2 is a, 6 is b, and 1 is c
a + b > c
2 + 6 > 1
8 > 1 -> <em>TRUE
</em>
b + c > a
6 + 1 > 2
7 > 2 -><em> TRUE
</em>
c + a > b
1 + 2 > 6
3 > 6 -> <em>FALSE
</em>
<u>Option B
</u>
In order to make a triangle: a + b > c and b + c > a and c + a > b
3 is a, 3 is b, 2 is c
a + b > c
3 + 3 > 2
6 > 2 -> <em>TRUE
</em>
b + c > a
3 + 2 > 3
5 > 3 -> <em>TRUE
</em>
c + a > b
2 + 3 > 3
5 > 3 -> <em>TRUE
</em>
OPTION B IS A TRIANGLE
Option C and D are automatically incorrect because Option B is incorrect. But, the same process would go to the end.
Answer: Option B
Answer:
0.9113
Step-by-step explanation:
Given :
Sample standard deviation of Stock X = 4.665
Sample standard deviation of Stock Y = 8.427
Sample Covariance = 35.826
The Correlation Coefficient, R is related to sample covariance and standard deviation using the formular :
R = Covariance(X, Y) / (SD(X) * (SD(Y))
R = 35.826 / (4.665 * 8.427)
R = 35.826 / 39.311955
R = 0.9113
Hence, correlation Coefficient, R = 0.9113 which depicts a strong positive relationship.
