Answer:
=m2+6mn+9n2
Step-by-step explanation:
=(m+3n)(m+3n)
=(m)(m)+(m)(3n)+(3n)(m)+(3n)(3n)
=m2+3mn+3mn+9n2
Answer:
Ф = CO/(6 units)
Step-by-step explanation:
The formula for arc length is s = rФ, where Ф is the central angle. This can be solved for Ф, the central angle:
arc length
Ф = ------------------
radius
If the given arc length is represented by CO, then the central angle is
Ф = CO/(6 units)
Answer:
There are a 25% probability that Christine fails the course.
Step-by-step explanation:
We have these following probabilities:
A 50% probability that Christine finds a tutor.
With a tutor, she has a 10% probability of failling.
A 50% probability that Christine does not find a tutor.
Without a tutor, she has a 40% probability of failing.
Probability that she fails:
10% of 50%(fail with a tutor) plus 40% of 50%(fail without a tutor). So
There are a 25% probability that Christine fails the course.
Answer:
mean=87
median=87
Step-by-step explanation:
mean=sum of test score/number of subject
mean=79+91+93+85+86+88/6
mean=522/6
mean=87
Literal meaning of median is medium.
To find the number which lies in the medium, we must rearrange the number in ascending.
79, 91, 93, 85, 86, 88
79, 85, 86, 88, 91, 93
86+88/2=87

The speed that Morris is travelling is 0.3 ft/s
<h3>Calculating the speed of a body</h3>
Speed is the ratio of distance covered with respect to time.
Given the following parameters
Speed of Annesha = 50mi/hr
Speed of Moris = 3ft/s less than Aneesha
Convert 50mi/hr to ft/hr
50mi/hr = 73.3ft/s
Speed of Morris = 73.3 - 3
Speed of Morris =70.3 ft/s
Hence the speed that Morris is travelling is 0.3 ft/s
