(0,-2)(4,6)
first we find the slope by using the slope formula : slope(m) = (y2 - y1)/(x2 - x1)
slope(m) = (6 - (-2) / (4 - 0) = (6 + 2)/4 = 8/4 = 2
point slope form : y - y1 = m(x - x1)... 2 answers are possible
y - y1 = m(x - x1)
slope(m) = 2
using points (0,-2)....x1 = 0 and y1 = -2
y - (-2) = 2(x - 0)
y + 2 = 2(x - 0) <=== here is one answer
y - y1 = m(x - x1)
slope(m) = 2
using points (4,6)...x1 = 4 and y1 = 6
y - 6 = 2(x - 4) <== here is the other answer
Answer:
Graph C
Step-by-step explanation:
The answer is c.) 2%. Since the question is talking about false negatives, meaning the chance that the results are false, then we take a look at the 98% which represents the chance of giving an accurate result for the people who are not infected meaning for those who are positive. Thus, the answer is 2% because this is the remaining percentage if 100-98%.
Answer: 61 children attended the musical last night.
Step-by-step explanation:
Let x represent the number of children that attended the musical last night.
Let y represent the number of adults that attended the musical last night.
The musical charges $3.50 for children's tickets and $5.00 for adults tickets. If the tickets sales totaled $823.50. It means that
3.5x + 5y = 823.5- - - - - - - - - - 1
Last night, twice as many adults attended the musical than children. It means that
y = 2x
Substituting y = 2x into equation 1, it becomes
3.5x + 5 × 2x = 823.5
3.5x + 10x = 823.5
13.5x = 823.5
x = 823.5/13.5
x = 61
y = 2x = 2 × 61
y = 122
Answer:
0.1
Step-by-step explanation:
10,000 * (1/100,000) = 0.1
