Poppy felix and Alex sell 700 raffle tickets between them.

prohojiy [21]

First 700-25=675

Poppy= 2F (F as in Felix, since she sells twice as much)
Alex = (Now equals 2F as well, cus we already took away the 25)
And well.... Felix is just felix so add that all up

F+F+F+F+F=5F

675/5=135!
Now according to that 135 is how many felix sold

Felix=135
Poppy=270
Alex=295

The height of an object tossed upward with an initial velocity of 120 feet per second is given by the formula h = −16t2 + 120t,

AleksAgata [21]

Answer:

7.5 seconds

Step-by-step explanation:

$h = - 16 {t}^{2} + 120t \\ \because \: we \: have \: to \: find \: the \: time \: required \: \\ for \: the \: object \: to \: return to \: its \: \\ point \: of departure. \\ \therefore \: plug \: h = 0 \: in \: the \: given \: euation. \\ \therefore \: 0 = - 16 {t}^{2} + 120t \\ \therefore \:16 {t}^{2} - 120t = 0 \\ \therefore \:8t(2t - 15) = 0 \\ \therefore \:8t = 0 \: \: or \: \: (2t - 15) = 0 \\ \therefore \:t = \frac{0}{8} \: or \: t = \frac{15}{2} \\ \therefore \:t = 0 \: or \: t = 7.5 \\ \because \: t = 0 \: is \: not \: possible \\ \huge \purple{ \boxed{ \therefore \: t = 7.5 \: seconds}}$

Thus, the time required for the object to return to its point of departure is 7.5 seconds.

Find the probability of no more than 2 successes in a trial of 5 in which the probability of success in any one trial is 18%

SSSSS [86.1K]

Answer:

0.956

Step-by-step explanation:

X is the random variable representing the number of successes in the experiment in question;

X is represented by a binomial distribution with 5 trials and 0.18 probability of success, X~B (5, 0.18);

The probability of r successes, P(X=r), is found using the formula shown in second pic;

Working is shown in the other pic.
