Step-by-step explanation:
Combine like terms
Divide both sides of the equation by the same term
Simplify
Answer:
Yes, the student is correct
Step-by-step explanation:
Given
Required
Does it represent the x intercept
At the x intercept, the value of x is 0.
So, the function 
becomes 
can be compared to
Hence, the student is correct
The answer would be 20. Because the whole angle would have to be 90 so you already have 30 so that leaves you with 60 which you divide by 3 and gives you 20
Answer:
No, because the 3 angles of a triangle must add up to 180 degrees and yours only add up to 55
Step-by-step explanation:
Answer:0.8413
Step-by-step explanation:
Mean= 188, Std Dev. =20.8, Z=(x-mean)/Std Dev
P(X less than 167.2)= P(Z less than (167.2-188)/20.8)
=P(Z less than (-20.8/20.8))
=P(z less than -1)= P(Z less 1)
The value of 1 in the normal distribution table is 0.3413
So we add 0.5 to 0.3413 =0.8413
