Answer: Dozen donuts cost in 1970 is $19.49.

Step-by-step explanation:

Since we have given that

Consumer price index in 1960 = 29.6

Consumer price index in 1970 = 48.2

Difference between 1960 and 1970 in terms of consumer price index would be

48.2-29.6\\\\=18.6

Cost of dozen donuts in 1960 = $0.89

And the price of donuts increased at the same rate as the CPI from 1960 to 1970.

so, the cost of dozen donuts would be

\$18.6+\$0.89\\\\=\$19.49

Hence, Dozen donuts cost in 1970 is $19.49.

Suppose that there are 15 antennas in a store, of which 3 are defective. Assume all the defectives and all the functional antenn
ohaa [14]

Answer:

Step-by-step explanation:

Total number of antenna is 15

Defective antenna is 3

The functional antenna is 15-3=12.

Now, if no two defectives are to be consecutive, then the spaces between the functional antennas must each contain at most one defective antenna.

So,

We line up the 13 good ones, and see where the bad one will fits in

__G __ G __ G __ G __ G __G __ G __ G __ G __ G __ G __ G __G __

Each of the places where there's a line is an available spot for one (and no more than one!) bad antenna.

Then,

There are 14 spot available for the defective and there are 3 defective, so the arrange will be combinational arrangement

ⁿCr= n!/(n-r)!r!

The number of arrangement is

14C3=14!/(14-3)!3!

14C3=14×13×12×11!/11!×3×2

14C3=14×13×12/6

14C3=364ways

Find the leg of each isosceles right triangle when the hypotenuse is of the given measure. Given = 8 cm.
kogti [31]
An isosceles right triangle is composed of a right angle and two congruent acute angles. In this case, 90 + 2x = 180 where x is the acute angle. x is equal to 45 degrees. Using sine law, 8/sin 90 = y / sin 45 where y is the leg of the triangle. the leg's length is equal to 4 sqrt 2.
