After simplifying, you should get u-9. Or if you want what u equals. Then I think you answer will be u=9

Use the distributive property to get rid of the parentheses:
-3(u+3)+4u=0
-3u-9+4u=0
Simplify to get answer by isolating the variables:
-3u-9+4u=0
-3u+4u=9
u=9
The solution would be 9, u=9

Which algebraic expression shows the average melting points of helium, hydrogen, and neon if h represents the melting point of h

Monica [59]

Given:
h = melting point of helium
j = melting point of hydrogen
k = melting point of neon

Number of values = 3
Therefore, the average is
(Sum of values)/(Number of values) = (h+j+k)/3

Answer:
The average melting point of helium, hydrogen, and neon is
(h+j+k)/3

37% of women consider themselves fans of professional baseball. you randomly select six women and ask each if she considers hers

valina [46]

Answer:

(a) 2.22

(b) 1.3986

Step-by-step explanation:

Let X denote the number of women who consider themselves fans of professional baseball.

The proportion of women who consider themselves fans of professional baseball is, p = 0.37.

A random sample of n = 6 women are selected and each was asked if she considers herself a fan of professional baseball.

Each woman's reply is independent of the others.

The random variable X thus follows a binomial distribution with parameters n = 6 and p = 0.37.

(a)

Compute the mean of the binomial distribution as follows:

$\text{Mean}=np=6\times 0.37=2.22$

(b)

Compute the variance of the binomial distribution as follows:

$\text{Variance}=np(1-p)=6\times 0.37\times (1-0.37)=1.3986$

(c)

Compute the standard deviation of the binomial distribution as follows:

$\text{Standard Deviation}=\sqrt{np(1-p)}=\sqrt{6\times 0.37\times (1-0.37)}=1.183$

A garden snail moves 1/6 foot in 1/3 hour. This is unit rates. Please explain your answer.

Alenkinab [10]

1/6 foot 0.16666667 ft
________ = ________________ = 0.50 ft/hr
1/3 hour 0.33333333 hr

A unit rate is identified as a rate with 1 in the denominator. Therefor, a garden snail moves 0.50 feet per 1 hour.
