Answer:
D..... 3 lines of Symmetry
Answer:
sin© = 3/5
Cos© = 4/5
Tan© = 3/4
Explanation:
The opposite (opp) side of the right angle triangle is the side facing the angle ©
The hypothenus (hyp) side is the longest side,
The adjacent (adj) side is the third side.
sin© = opp/hyp
Cos© = adj/hyp
Tan© = opp/adj
Let x be the price of each pen and y be the price of each pencil. From the given, the equations that are described are,
6x + 8y = 8.50
4x + 4y = 5
Solving for x and y simultaneously gives an answer of x = 0.75 and y = 0.5.
Thus, each pen costs $0.75 and each pencil costs $0.50.
Answer:
False
Step-by-step explanation:
We are given the following in the question:
Pearson correlation = 1.30
Pearson coefficient:
- The range of Pearson coefficient is from [-1,1]
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
Since, the given coefficient of Pearson does not lies in the range, it cannot express relation between two quantities.
Thus, a value of 1.30 does not indicates a strong correlation.
Thus, the given statement is false.
Answer:4/25
Step-by-step explanation: 16%=16/100
that equals 0.16
0.16/1 x 100/100= 16/100
Which simplfies to 4/25.
