Answer: 405 students
Step-by-step explanation:
From the question, Banneker Middle School has 750 students and we are told that Lynn surveys a random sample of 50 students and finds that 27 have pet dogs. The number of students at the school that are likely to have pet dogs goes thus:
Since out of 50 students surveyed, 27 have pet dogs, this means we multiply the fraction by 750. This can be mathematically written as:
= 27/50 × 750
= 27 × 15
= 405
This means 405 students are expecting to have pet dogs.
A triangle equals 180° so set up the equation as
58+73+12x+1=180
132+12x=180 (I got 132 by adding 58,73,1)
Subtract 132 from both sides
You should get 12x=48
Divide both sides by 12
X=4
Answer:
y=-1/3x-5
Step-by-step explanation:
Find the slope(m), it is rise over run. this line doesnt "rise" per se; it goes down. You have to see at what rate. you find the rise with the y values. here you go from -3 to -7. the rise is <u>-4</u> units. the run you find with the x values. here you go from -6 to 6. the run is <u>12</u> units. your rise over run is the fraction <u>-4/12</u>. This can be simplified to <u>-1/3</u>. Now you find the y-intercept(b). the graph intercepts the y axis at (0,-5). now you plug it into y=mx+b. y=-1/3x-5
Answer:
So we always look for to find a correlation. 0.81 is known as, Large Positive Linear Association. There are many variables, in this case, this "man" is part of other variables. So by removing HIM, the correlation goes from 8 to 9. It is still significant. However, it can be because of many reasons. Perhaps he has diabetes or cancer and was removed. *Hypothetically
