The random variable X, representing the number of cherries in a cherry puff, has the following probability distribution:x: 4 - 5

marta [7]

Answer:

Step-by-step explanation:

Given is the probability distribution of a random variable X

X 4 5 6 7 Total

P 0.2 0.4 0.3 0.1 1

x*p 0.8 2 1.8 0.7 5.3

x^2*p 3.2 10 10.8 4.9 28.9

a) E(X) = Mean of X = sum of xp = 5.3

$Var(x) = 28.9-5.3^2=0.81$

Std dev = square root of variance = 0.9

------------------------------------

b) For sample mean we have

Mean = 5.3

Variance = var(x)/n = $\frac{0.81}{{36} } \\=0.0225$

c) $P(\bar X$

If r(x) = 3x – 1 and s(x) = 2x + 1, which expression is equivalent to (StartFraction r Over s EndFraction) (6)?

Airida [17]

Answer:

$\dfrac{r}{s}(6)=\dfrac{3(6)-1}{2(6)+1}$

Step-by-step explanation:

We know that for any two function f(x) and g(x) ,

$\dfrac{f}{g}(x)=\dfrac{f(x)}{g(x)}$

Given functions : $r(x)=3x-1$ and $s(x)=2x+1$

Then, $\dfrac{r}{s}(x)=\dfrac{r(x)}{s(x)}$

$\Rightarrow\ \dfrac{r}{s}(x)=\dfrac{3x-1}{2x+1}$

At x= 6 , we get

$\dfrac{r}{s}(6)=\dfrac{3(6)-1}{2(6)+1}$

The , The expression is equivalent to $\dfrac{r}{s}(6)=\dfrac{3(6)-1}{2(6)+1}$

When we further simplify it , we get $\dfrac{r}{s}(6)=\dfrac{18-1}{12+1}=\dfrac{17}{13}$

The formulas for power and work are p=w/t and w=fd, where P is the power, W is the work done, t is the time, F is the force, and

shepuryov [24]

This is the concept of algebra, given that:
power is given by:
p=w/t
and
work is given by:
w=fd
then substituting the formula for work in our top formula we get:
p=(fd)/t
Therefor we conclude that displacement d is directly proportional to power

The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a mean temperature

Bingel [31]

Answer:

There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees

Step-by-step explanation:

Given : Claim : The mean temperature of the refrigerators is different from 45 degrees

To Find :Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.

Solution:

Claim : The mean temperature of the refrigerators is different from 45 degrees

So, Null hypothesis : $H_0:\mu = 45$

Alternate hypothesis : $H_a:\mu \neq 45$

We are given that the conclusion is to reject the null hypothesis.

So, we can say that the claim is true that mean temperature is different from 45 degrees.

There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
