Lets break this down here.
First- 198 rounded would be 200
Then- we add 727 which would be 927
if you were to round that it would be 930
Answer:
Step-by-step explanation:
I'm sure by now you have learned the difference between mass and weight. Mass will never change regardless of where something is while weight changes depending upon the pull of gravity. If we want the mass, then we have to take the weight on Earth and divide by its pull of gravity. The equation for that will be
W = mg where W is the weight in Newtons, m is mass and g is gravity.
685 = m(9.8) so
m = 7.0 × 10¹ kg
Now that we know that mass, and also because we know that the mass is constant no matter where the astronaut is, we can find his weight on Jupiter.
W = (7.0 × 10¹)(25.9) so
W = 1800 N
Answer:
The confidence interval is
Step-by-step explanation:
From the question we are told that
The sample mean is
The standard deviation is
The sample size is
given that the confidence level is 85% then the level of significance is mathematically represented as
Next we obtain the critical value of from the normal distribution table the value is
Generally the margin of error is mathematically represented as
=>
=>
The 85% confidence interval is mathematically represented as
=>
=>
Answer:
a) -0.5
Step-by-step explanation:
Correlation
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.
Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5
Answer:
Any number >25
Step-by-step explanation:
Any number >25.
It could be 25.01, 10000, etc
