Answer:
I don't remember the name of the law, but it states that when resistors are connected in series they put up one singular resistance. so,
Let smaller resistance be x
greater resistance is 3x
According to the question,
x+3x=12
4x=12
x=3
therefore,
resistors are of 3 ohms and 3×3=9 ohms

Answer:
d. The median and the IQR
Step-by-step explanation:
The median separates the upper half from the lower half of a set. So 50% of the values in a data set lie at or below the median, and 50% lie at or above the median. This means that the median is the appropriate numerical measure to describe the center.
The first quartile(Q1) separates the lower 25% from the upper 75% of a set. So 25% of the values in a data set lie at or below the first quartile, and 75% of the values in a data set lie at or above the first quartile.
The third quartile(Q3) separates the lower 75% from the upper 25% of a set. So 75% of the values in a data set lie at or below the third quartile, and 25% of the values in a data set lie at or the third quartile.
The quartiles are used to measure the spread of a data-set.
The interquartile range(IQR), is Q3-Q1.
So the correct answer is:
d. The median and the IQR
Answer:
The first option is correct 7.1 cm
Therefore the length segment AC is 7.1 cm.
Step-by-step explanation:
Given:
In Right Angle Triangle DAC
∠A = 90°
∠D = 62°
CD = 8 cm = Hypotenuse
To Find:
AC = side opposite to angle D = ?
Solution:
In Right Angle Triangle DAC , using Sine Identity we have

Substituting the values we get

Therefore the length segment AC is 7.1 cm.
