A is the correct answer. PEMDAS for single step and double step equations alike.
Answer:
the answer is 20cm
Step-by-step explanation:
Area = Length times width
P=2(l+b)
=2(200•15)
=2.3000
=6000
Again,
A=lb
=200.15
=3000
Answer:
Step-by-step explanation:
Given
---- proportion of watches with defects
--- Number of watches
Solving (a): Represent at least 215 of 400 are defective
In inequalities, at least means:
So, the probability is represented as:
Solving (b): Calculate
Normal or Poisson: Normal distribution is characterized by 2 parameters and .
These two parameters can be easily calculated from the given parameters in the question. So, we solve using normal distribution
Start by calculating the mean
Calculate standard deviation
By continuity correction, we have:
So, we have:
Calculating , we have:
Calculate z score
So, we have:
Using the z score probability table, we have:
So, we have:
Answer:
A: Angle J
Step-by-step explanation
If the two triangles are congruent then their corresponding angles are also congruent. This means that angle P is congruent to angle J, angle Q is congruent to angle K and angle R is congruent to angle L. Hope this helps :D
