Set up a ratio comparing the sample portion to the whole portion.
x= # of all dogs likely to have chip
Sample: 8 out of 50
Whole: x out of 2,300
8/50= x/2300
cross multiply
(50*x)= (8*2300)
50x= 18400
divide both sides by 50
x= 368
ANSWER: 368 dogs in Clarkson are likely to have a microchip.
Hope this helps! :)
Ratios of Area of the two squares = 25:9
So then let the areas be A1 = 25A and A2 = 9A, A is common element
Side of the smaller area S2 = 30 meters
Area of the smaller square A2 = 30 x 30 = 900
We have area of smaller square as 9A = 900 => A = 100
Area of the large square = 25A = 25 x 100 = 2500.
Hence S1^2 = 2500 => S1 = 50 meters which is 20 meters longer than the
side of the smaller square.
Answer:
the correct answer is d.
Step-by-step explanation:
i hope this helps :)
F(x) = -x² + 4
g(x) = 6x
(g - f)(3) = 6(3) - (-(3)² + 4)
(g - f)(3) = 18 - (-9 + 4)
(g - f)(3) = 18 - (-5)
(g - f)(3) = 18 + 5
(g - f)(3) = 23
