Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

If two lines are coplanar, then lines should be parallel or they should intersect each other.

It means, perpendicular lines always intersect to each other but parallel lines never.

So, If the lines are perpendicular then it must intersect, other wise the lines never intersect.

so, the lines are coplanar.

Hence, Option 'c' is correct.

Can someone fr help me with this like right now i’ll appreciate it sm
rjkz [21]

Step-by-step explanation:

Since

\frac{108}{72}  =  \frac{3}{2}

\frac{72}{48}  =  \frac{3}{2}

\frac{48}{32}  =  \frac{3}{2}

The function has a constant factor so we have a exponential function.

The equation of a exponential function is

y = a(b) {}^{x}

Where a is the initial value and b is the growth factor

The growth factor is 3/2,

The initial value in 32

y =  32 ( \frac{3}{2} ) {}^{x}

Plug in 4 for x.

You will get 162

Plug in 5 for x you will get

243.

2013- 162

2014- 243

just need to multiply and axpand ?

( {x}^{2}  + 2)( {x}^{3}  - 4x + 2) =  {x}^{2} ({x}^{3}  - 4x + 2) + 2({x}^{3}  - 4x + 2) \\  =  {x}^{5}  - 4 {x}^{3}  + 2 {x}^{2}  + 2 {x}^{3}  - 8x + 4 \\  =  {x}^{5}  - 2 {x}^{3}  + 2 {x}^{2}  - 8x + 4

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

Step-by-step explanation:

1. Simplify 4(x^2 -1) to 4x^2 -4

then add that to 6x^2

2. 4a^5 - 2a^5 = 2a^5 and

4b+b = 5b
