42 and 63 both are at the rate of 2 to 3 and they add up to 105
Answer:
you will have $37.92 left over and they can buy 19 pairs
Step-by-step explanation:
The given function : h(x) = 6 - x
We know that for any functions f(x) and g(x)
f*g (x)=f(x)\times g(x)
Therefore , h*h (x)=h(x)\times h(x)
h*h (x)=(6-x)(6-x)=(6-x)^2
h*h (x)=(6)^2-2(6)(x)+x^2 [ Using identity (a-b)^2=a^2+2ab+b^2 ]
h*h (x)=36-12(x)+x^2
\-------->\ h*h (x)=36-12(x)+x^2 Now, at x= 10 , we get
h*h (10)=36-12(10)+(10)^2
h*h (10)=36-120+100=36+100-120=136-120=16
Hence, the value of (h*h)(10) = 16

Answer:
7 / 13
Step-by-step explanation:
The number of cards in a standard deck = 52
Number of red cards in a deck = 26
Number of queens in a deck = 4
Selecting a card at random ;
Probability of picking a red card ;
P(red card) = number of red cards / number of cards in deck
P(red card) = 26 / 52
P(queens card) = number of queens / number of cards in deck
P(queens card) = 4 / 52
Number of red queen cards = (red n queen) = 2
P(red or queens card) = P(red) + P(queens) - P(red n queen)
P(red or queens card) = 26/52 + 4/52 - 2/52
= (26 + 4 - 2) / 52
= 28 /52
= 7 / 13
