Answer:
The probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.
Step-by-step explanation:
Since a cage holds two litter of rats, and one litter comprises one female and five males, while the other litter comprises seven females and two males, and a random selection of two rats is done, to find the probability that the two rats are from the same litter the following calculation must be performed:
6/15 x 5/14 = 0.1428
9/15 x 8/14 = 0.3428
Therefore, the probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.
Dividing 3.6 by 0.25 follows the following generic approach : You have
to firstly need to multiply both divisor and dividend by that number
such that the divisor becomes a whole number first .
So we multiply both dividend and divisor by 100 such that the problem converts to 3.6*100/0.25*100 = 360 being divided by 25 .
So the approach to divide a number froma decimal number is to first
convert problem into dividing the number from a whole number , by
multiplying both the number and divisor from the approriate number .
Which was in above problem comes out to be 100 .
The length of a face from the top of the forehead to the chin is 17 feet.
the width of the phases to feet given that and video Skies T-shirt has a length of 29 inches and a width of 20 in
so, the length of the face must fit the length on the t-shirt
So, the scale will be
so, the drawing scale = 29 inch : 17 feet
feet = 12 inch
so, 29 inch : 17 * 12 inch
so, the drawing scale = 29 : 204
so, the length of face will not above 29 inch
and the width not above 20 inch
