Answer:

68.75 hotdogs

Step-by-step explanation:

lets say x = number of hotdogs

27.5/4 = x/10

use cross multiplication:

27.5 (10) = 4(x)

multiply

275 = 4x

divide both sides by 4 to isolate x

x = 68.75

Answer:

${x}^{2} + 0x + 1$

Step-by-step explanation:

$for \: g (fx) \:the \: function \: of \: f \: is \: inserted \: into \: the \: x \: for \: the \: g$

So the eqn becomes

$({x}^{2} - 1) + 2$

AND this equal to

${x}^{2} + 1$

Hence the variable x has 0 as its coefficient.

Simplify 59.95m − 30 + 7.95m + 45 + 9.49m

Ksju [112]

Answer:

77.39m + 15

Step-by-step explanation:

To simplify, we add all the common terms among themselves.

We have terms with the unit m and terms without any unit. So we add them among themselves.

59.95m − 30 + 7.95m + 45 + 9.49m

(59.95 + 7.95 + 9.49)m + (-30 + 45)

77.39m + 15

If X is a binomial random variable associated with a binomial experiment with

Makovka662 [10]

For a binomial distribution over $n$ trials and with success probability $p$ , the mean $\mu$ and standard deviation $\sigma$ ar such that

$\begin{cases}\mu=np\\\sigma=\sqrt{np(1-p)}\end{cases}$

$6=\sqrt{np(1-p)}\implies np-np^2=36$
$54=np\implies54-54p=36\implies p=\dfrac13$
$54=\dfrac n3\implies n=162$
