Answer:
0.665
Step-by-step explanation:
Given: 100 people are split into two groups 70 and 30. I group is given cough syrup treatment but second group did not.
Prob for a person to be in the cough medication group = 0.70
Out of people who received medication, 34% did not have cough
Prob for a person to be in cough medication and did not have cough
=
Prob for a person to be not in cough medication and did not have cough
=
Probability for a person not to have cough
= P(M1C')+P(M2C')
where M1 = event of having medication and M2 = not having medication and C' not having cough
This is because M1 and M2 are mutually exclusive and exhaustive
SO P(C') = 0.397+0.2=0.597
Hence required prob =P(M1/C') = 
The remainder is or answer is 6
We are given area of the ribbon = 144 square inches.
We know formula for side of a square =
.
Plugging value of area in the formula, we get
Side of the square 
= 12 inches.
Sonya wants to sew ribbon along each side of a square pillow.
So, we need to find the perimeter of the square pillow.
<h3>Perimeter = 4 × side = 4 × 12 = 48 inches.</h3><h3>Therefore, she buy 48 inches of ribbon to have the exact amount that she needs.</h3>
Answer:
Option A and B
Step-by-step explanation:
sides of the triangle have been given as 15, 15.8, 30 units.
angles of the same triangle has been given as 70°, 80°, [180-(70+80)] or 30°.
Here we see all sides and all the angles of the given triangle have different measures ( all the three sides and angles are different )
By the definition of scalene triangle the given triangle will be scalene.
Since all three angles of the triangle are acute angles (less than 90°).
The second answer, cause it best shows the equation, but they just moved the numbers around. It is also the only equation with all the same numbers used in the original equation, too
