Answer:
y=7/2x−10
Step-by-step explanation:
Let's solve for y.
7x−2y=20
Step 1: Add -7x to both sides.
7x−2y+−7x=20+−7x
−2y=−7x+20
Step 2: Divide both sides by -2.
−2y/2=−7x+20/2
y=7/2x−10

Answer:
<h2>A. 3</h2>
Step-by-step explanation:
Formula for locating the Median of a grouped data = (N+1)/2 th where
N is the total number of defects.
Total defects = 10+18+13+15+9+12
Total defects = 77
Median value = (77+1)/2 th value
Median value = 78/2 = 39th value.
We will cummulate the frequency (number of defects up to the 38th value) and locate the corresponding observation value.
On cummulating:
10+18+13 = 41
<em>We can see that the value of 38 falls on the third column(13), hence the median will be the equivalent number of observations i.e 3.</em>
Therefore the sample median is 3
The side of the square is 5.9 cm
<u>Step-by-step explanation:</u>
Area of the circle = 56 square cm
Side of the square= x
Area = π(r x r)
56 = π (r x r)
√17.83 = r
r = 4.22 cm
Diameter = 8.44cm
The diameter is equal to the diagonal of the square.
8.44 = x√2
x = 8.44/√2
= 5.9 cm
The side of the square is 5.9 cm
