Answer:

  no

Step-by-step explanation:

An equation representing a proportional relationship looks like ...

  y = kx

where k is the constant of proportionality. A notable feature of this equation is that its y-intercept is zero.

Your expression has a y-intercept of +4, so does not represent a proportion.

_____

<em>Additional comment</em>

Strictly speaking, a proportion is a statement of equality of two ratios. <em>An expression cannot be a proportion</em>. We interpreted your question to be ...

  does y = 3x+4 express a proportional relationship?

Suppose in the population, the Anger-Out score for men is two points higher than it is for women. The population variances for m
tatuchka [14]

Answer:

a)= 2

b) 6.324

c) P= 0.1217

Step-by-step explanation:

a) The mean of the sampling distribution of X`1- X`2 denoted by ux`-x` = u1-u2 is equal to the difference between population means i.e = 2 ( given in the question)

b) The standard deviation of the sampling distribution of X`1- X`2 ( standard error of X`1- X`2) denoted by σ_X`1- X`2 is given by

σ_X`1- X`2 = √σ²/n1 +σ²/n2

Var ( X`1- X`2) = Var X`1 + Var X`2 =  σ²/n1 +σ²/n2

so

σ_X`1- X`2 =√20 +20 = 6.324

if the populations are normal the sampling distribution X`1- X`2 , regardless of sample sizes , will be normal with mean u1-u2 and variance σ²/n1 +σ²/n2.

Where as Z is normally distributed with mean zero and unit variance.

If we take X`1- X`2= 0 and u1-u2= 2  and standard deviation of the sampling distribution = 6.324 then

Z= 0-2/ 6.342= -0.31625

P(-0.31625<z<0)= 0.1217

The probability would be 0.1217

The volume of a sphere whose diameter is 18 centimeters is
Akimi4 [234]

Answer:

volume before reducing is 8 times the volume after reducing

Step-by-step explanation:

volume before reducing=

V=4/3πr³=

V=4/3π(9)³=972π cm³

diameter reduced to half=18/2=9 cm

radius=d/2=9/2=4.5 cm

volume of sphere when diameter reduced by 1/2=

V=4/3πr³

v=4/3 (π)(4.5)³=121.5π

<h2>volume before reducing is <u>8</u> times the volume after reducing</h2>

How do you write 26.2 as a mixed number in simplest form
Arte-miy333 [17]
To write 26.2 as a mixed number in the simplest form, do the following:
26.2 = 26 + 0.2
         = 26 + 2/10

Note that 
\frac{2}{10}= \frac{2 \times 1}{2 \times 5}  = \frac{1}{5}

Therefore
26.2 = 26 \, \frac{1}{5}  \\

Answer:  26 \,  \frac{1}{5}
