Answer:
−10x + 4.35xy + 55y + 9.58
Step-by-step explanation:
Step 1: Collect like terms.
(6x − 16x) + 4.35xy + (16y + 39y) + 9.58
Step 2: Simplify and you're done!
−10x + 4.35xy + 55y + 9.58
3(9+5) all over 6
Multiply the number outside the parenthesis with the numbers inside the parenthesis
27+15 all over 6
Add 27 and 15 together.
42/6
Divide 42 by 6.
Final Answer: 7
So you were correct! The answer is 7
Answer: D
Sound waves with higher amplitudes sound louder than sound waves with lower amplitudes. Constructive interference will make a sound louder while destructive interference will make a sound quieter. Two waves that add together may have different frequencies.
Your answer is x<3. hope this helps.
Answer:
[0.184, 0.266]
Step-by-step explanation:
Given:
Number of survey n =280
Number of veterans = 63
Confidence interval = 90%
Computation:
Probability of veterans = 63/280
Probability of veterans =0.225
a=0.1
Z(0.05) = 1.645 (from distribution table)
Confidence interval = 90%
So,
p ± Z*√[p(1-p)/n]
0.225 ± 1.645√(0.225(1-0.225)/280)
[0.184, 0.266]
