Answer:
17 - 7m
Step-by-step explanation:
Assuming you require to subtract the expressions, then
16 + m - (8m - 1) ← distribute parenthesis by - 1
= 16 + m - 8m + 1 ← collect like terms
= 17 - 7m
Answer:
a) P(X=41)= 0.0086 = 0.86%
b) P(36≤X≤38)== 0.1215 = 12.15%
c) would be unusual that fewer that 20 murders were cleared because P(X≤20) = 0.000081 =0.0081%
Step-by-step explanation:
if the random variable X= number of cleared murders , then X follows a binomial distribution:
P(X=x)= n!/[(n-x)!*x!]*p^x*(1-p)^(n-x)
where P(X=x)= probability of x cleared murders, n= number of murders selected=50 , p= probability for a murder to be cleared (67%)
therefore
a) P(X=41)=50!/[(50-41)!*41!]*0.67^41*0.33^(50-41)= 0.0086
b) P(36≤X≤38)= P(X≤38) - P(X≤36) = 0.9371- 0.8156 = 0.1215
c) P(X≤20) = 0.000081
therefore would be unusual that fewer that 20 murders were cleared
You will add the two numbers together and add the t as well to make 33t
b or the second option
The correct answer for the question that is being presented above is this one: "w(w + 2) = 48." John has 48 square centimeter tiles he wants to use to create a mosaic. He wants the mosaic to be rectangular with a length that is 2 centimeters longer than the width.
Let w = width
Let (w+2) = length
Area = w(w+2).
Answer:
See explanation
Step-by-step explanation:
From the attachment, the question has been answered. However, the explanation is as follows;
Given that
This means that
See attachment (1)
Step 1: Locate point 7 on the x axis
Step 2: Locate point 4 on the y axis
Trace these two points until they intersect.
The point at which they intersect, is the required point (7,4) --See attachment (2)
