Step-by-step explanation:
x^2 = -25
there is a solution if you know imaginary numbers
if you do not stop now and say no solution
else
take the square root
x = sqrt (-25)
x =sqrt(-1) sqrt(25)
x=+- 5i
x = 5i, -5i
x^2 =18
take the square root of each side
x =+-sqrt(18)
x=+- sqrt(9)sqrt(2)
x=+- 3sqrt(2)
x=3sqrt(2), -3sqrt(2)
Answer: 2=.36, 3=.48, 4=.16
Step-by-step explanation:
If we let "S" represent 1 baby and "D" represent 2 babies, the sample space for the chimpanzee's 2 pregnancies is {SS, SD, DS, DD}.
We can find the probability of each possible outcome by multiplying the probability of the independent events leading to that outcome.
Outcomes:. Probability:
SS. .60 x .60 = .36
SD. .60 x .40 = .24
DS. .40 x .60 = .24
DD. .40x .40 =.16
Total. 1.00
Lastly group the similar outcomes. SD+DS= .48

Step-by-step explanation:
Correct option is B)
The circumference of the circle is 96 units.
Therefore, 2π×r=96
⇒r=
2×22
96×7
=15.27 units
Now, in the quadrilateral OLMN,∠OLM+∠LMN+∠MNO+∠NOL=360
o
Given that LM and MN are tangents to the circle, ∠OLM=∠ONM=90
o
∴∠NOL=360−90−90−60=120
o
The length of arc is given by rθ where θ is the angle made by the arc at the centre in radian.
Thus, arc length LN=15.27×
180
120π
=31.98
