Answer:
b. angle K is acute
Step-by-step explanation:
We're often told not to draw any conclusions from the appearance of a figure in a geometry problem. Here, angle K appears to be somewhat less than 90°, so angle K is acute.

<em>Additional comment</em>
This choice of answer is confirmed by the fact that the other two (visible) choices say the same thing. If one of them is correct, so is the other one. Hence they must both be incorrect. (An obtuse angle is more than 90°.)
For simple integer factors as this one has, you want to find two values for the quadratic in the form ax^2+bx+c. Let the two values be j and k. These two values must satisfy two conditions.
jk=ac=10 and j+k=b=11, so j and k must be 1 and 10.
Now replace bx with jx and kx...
2x^2+x+10x+5 now factor 1st and 2nd pair of terms.
x(2x+1)+5(2x+1)
(x+5)(2x+1)
Answer:
D.
Step-by-step explanation:
She cannot buy a negative number of notebooks. She can buy 0 notebooks, or 1 notebook, or 2, or 3, etc. The number of notebooks she buys must be a non-negative integer.
Answer: D.
The answer of m is -1 because if is -7 then the -13 and -7 will change reverse into positive so 7 + 5 + 13 = 25
Answer:
The answer is 0.105
Step-by-step explanation:
Let cars =C and motorcycles=M.
now, P(C)=76 percent =0.76
P(M)=12 percent=0.12
P(C∩M)=8 percent =0.08
Then, the probability that a person owns a motorcycle, given they own a car, is a conditional probability given by the definition
P(M/C)=
=
=0.105
Therefore, the answer is 0.105
I believe it is well understood.
