stans steakhouse has a sever to chef ratio of 5 to 2 the total number of severs and chefs is 42.How many severs does stans steak

amm1812

Answer:

Step-by-step explanation:

We need to figure out what 5 and 2 really mean in this scenario. So we add them together. 5+2=7

We then divide 42 by 7. 42/7=6

Afterward we multiple 5 by 6 to get the real number or servers. 5x6=30

And as a bonus (and also to check our work) we multiple 2 by 6. 2x6=12

5/2=30/12

A sample of 100 is drawn from a population with a proportion equal to 0.50. Determine the probability of observing between 43 an

diamong [38]

Answer:

The probability of observing between 43 and 64 successes=0.93132

Step-by-step explanation:

We are given that

n=100

p=0.50

We have to find the probability of observing between 43 and 64 successes.

Let X be the random variable which represent the success of population.

It follows binomial distribution .

Therefore,

Mean, $\mu=np=100\times 0.50=50$

Standard deviation , $\sigma=\sqrt{np(1-p)}$

$\sigma=\sqrt{100\times 0.50(1-0.50)]$

$\sigma=5$

Now,

$P(43\leq x\leq 64)=P(42.5\leq x\leq 64.5)$

$P(42.5\leq x\leq 64.5)=P(\frac{42.5-50}{5}\leq Z\leq \frac{64.5-50}{5})$

$=P(-1.5\leq Z\leq 2.9)$

$P(42.5\leq x\leq 64.5)=P(Z\leq 2.9)-P(Z\leq- 1.5)$

$P(42.5\leq x\leq 64.5)=0.99813-0.06681$

$P(43\leq x\leq 64)=0.93132$

Hence, the probability of observing between 43 and 64 successes=0.93132

Factor completely 2x5 + 10x4 − 22x3.

Luba_88 [7]

Given equation is :

$2x^{5}+10x^{4}-22x^{3}$ =0

Taking out $2x^{3}$ common we get,

$x^{2}+5x-11$ =0

Now solving this we get,

As 11 is not factor-able, we will solve it using the formula,

$x=\frac{-b+\sqrt{b^{2}-4ac}}{2a}$

a=1 b=5 and c=-11

we get,

$x=\frac{-5+\sqrt{69} }{2}$ and $x=\frac{-5-\sqrt{69} }{2}$
