Answer:
The correct answer is 
.
Step-by-step explanation:
A container contains tiles numbered from 1 through 40.
Let the experiment be to drawn a tile randomly from the container. The draws are carried on by replacement method. Then a second tile is drawn randomly.
Probability that the first tile is number 7 = 
= 
Probability that the second tile is number 25= =
Thus the probability of the first tile is number 7 and the second tile is number 25 is given by .
Step-by-step explanation:
The quadratic equation given to us is ,
→ 4v² + 6v - 88 = 0 .
So , wrt to standard form of a quadratic equation ax² + bx + c = 0 , the Zeroes are given by using the Quadratic formula as ,
⇒ x = -b ± √ ( b² - 4ac) / 2a
⇒ x = -6 ± √ [6² - 4 × 4 × (-88) ] / 2×4
⇒ x = -6 ± √ [ 36 + 1408 ] / 8
⇒ x = -6 ± √ 1444 / 8
⇒ x = -6 ± 38 / 8
⇒ x = -6 +38/ 8 , -6 -38 / 8
⇒ x = 32/8 , -44/8
⇒ x = 4 , -11/2
Here I took v as x . So we can replace it .

It’s 8 because in a diameter there are 2 parts so you divided 16 by 2 and u will get 8 and when u add 8 and 8 u get 16.
Answer:
80
Step-by-step explanation:
320 divided by 8 is 40 and 40 x 2 is 80
I believe it’s 7. Sorry if it’s wrong. Good luck !
