First, take two points from the graph. Call these points (a, b) and (c, d).
Next, find the slope. You can find this by doing (b-d)/(a-c).
Call the slope m. You will need this later.
Make an equation in slope intercept form (y = mx + b).
Now, take one of the points, and plug it into the equation.
mx + b has the same m as the slope.
From here, you can figure out b (the y-intercept).
To make a system, you do the same thing, but find where it is greater and lower.
Fr bro .. i feel the same
16 = 1/4x + 2.5...where x stands for diameter of large gear
16 - 2.5 = 1/4x
13.5 = 1/4x....multiply both sides by 4, eliminating the 1/4 on the right side
13.5 * 4 = x
54 = x.....the large gear is 54 cm
Answer:
The answer to the question is;
Yes, it is very significant as the number of of observed vaccinated children is below the number of actually vaccinated children by 78.
Step-by-step explanation:
The result of the survey of more than 13,000 children indicate that only 89.4 % had actually been and the P-value indicate that the chance of having a sample proportion of 89.4 % vaccinated is 1.1 %.
P is low at 0.011 for which however the proportion of those vaccinated is between 0.889 and 0.899 using a 95% confidence interval, whereby the decrease from 90 % believed to 89.9 % is small, albeit it depends on the size of the population.
At 89.4 %, in a sample of 13,000, the number of children expected to have been vaccinated but were missed is equal to 90 - 89.4 = 0.6 % = 0.006
Therefore the children missed = 78 children which is significant.
