Answer:
k=6/5=1.200 or k=2
Step by step Explanation:
Hey!
Now it is in fact possible for an equation to have no solutions or infinite solutions.
An equation getting infinite solutions would mean that you could choose any number for the variable ( ex. x or y ), and that number would make the equation true. To represent an equation with infinite solutions we'd use the infinite symbol.
An equation getting no solutions would just that. It would mean the equation has no solutions what so ever. You could plug in any number for the variable and every single time you would get no solution. In addition to the equation having no solutions, this would also mean that the equation is not true can never be true. To represent an equation with no solutions, we'd use a symbol that is a zero with a diagonal line through it.
Hope this helps!

Complete question :
The birthweight of newborn babies is Normally distributed with a mean of 3.96 kg and a standard deviation of 0.53 kg. Find the probability that an SRS of 36 babies will have an average birthweight of over 3.9 kg. Write your answer as a decimal. Round your answer to two places after the decimal
Answer:
0.75151
Step-by-step explanation:
Given that :
Mean weight (m) = 3.96kg
Standard deviation (σ) = 0.53kg
Sample size (n) = 36
Probability of average weight over 3.9
P(x > 3.9)
Using the z relation :
Zscore = (x - m) / (σ / √n)
Zscore = (3.9 - 3.96) / (0.53 / √36)
Zscore = - 0.06 / 0.0883333
Zscore = −0.679245
Using the Z probability calculator :
P(Z > - 0.679245) = 0.75151
= 0.75151

To solve this problem we can make a proportion.
6 5
-- = ---
10 x
to solve this proportion we can cross multiply and divide.
5 times 10 is 50. divided by 6 is 8.3
it will take her 8.3 minutes to run 5 laps
