Answer:
0.0098
Step-by-step explanation:
Probability of being pregnant:100/1000
=1/10.
98% chance:=98/100 ×1/10
=98/1000
Therefore the probability that she really is pregnant is: 0.098
Answer:
The point has a high leverage
Step-by-step explanation:
The point has a high leverage as it would act as an infinitesimal point that will have a very huge/drastic impact on the fit of the model, and this impact can be seen in such ways as listed below :
- Smaller coefficient of determination
- Higher sum of squares error
removing this point will eliminate these drastic impact and make the correlation to be better.
First, you would multiply: -13 = 70m - 2m. Then, you subtract the like terms, which would be 70m - 2m: -13 = 68m. You are looking for what m is, so you would divide 68 on both sides: m = - 13 / 68. In math, people would usually like fractions more than decimals, but if you are looking for the decimal number, it would be m ≈ - 0.19.
Answer:
Step-by-step explanation:
Let x represent the original number of saplings. Then the total number of saplings was 5x.
From these 5x saplings she planted 15 and had at most 20 left.
Rewriting this in symbolic form, we get: 5x - 15 ≤ 20.
Let's solve this for x. Add 15 to both sides to isolate 5x: 5x ≤ 35,
Solving for x, we divide both sides of this inequality by 5: x ≤ 7.
x represents the number of packages: x ≤ 7.
To graph this on a number line: place a dot at x = 7 and then an arrow pointing to the left of x = 7.
When Rita started, she had at most 7 packages of saplings.
Answer:
x = 10.6
y = 10.6
Step-by-step explanation:
To answer this question you will need to use trigonometry. If you don't already have an understanding of trigonometry, this will be very hard to explain. please let me know in the comments if you would like me to give it a go.
