After an oil spill, the ratio of contaminated water samples to clean
water samples in the ocean is 7:2. Jai
found 140 clean samples. How many
fewer samples were clean than were
contaminated?

A.70
B.140
C.350
D.490

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option

step-by-step explanation: w

a reflection across the x axis and a 90 degree rotation left and right.

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .

answer: the best estimate of the mean of the population = 14.

step-by-step explanation:

given: sheri surveyed eighty students, then generated three random samples of twenty-five student responses.

the sample mean=

⇒ the sample mean=

hence, the best estimate of the mean of the population = 14.
