Sales prices of baseball cards from the 1960s are known topossess a skewed-right distribution with a mean sale price of $5.25and

Serga [27]

Answer:

c. Skewed-right with a mean of $5.25 and a standard error of$0.28

Step-by-step explanation:

As we have given that Sales prices of baseball cards have a right-skewed distribution with a mean $5.25 and a standard deviation is $2.80.

Now, We know that if standard deviation = σ

then, standard error = $\frac{\sigma}{\sqrt{n}}$

As, we have standard deviation = $2.80

then standard error will be $\frac{2.80}{\sqrt{100}}$

⇒ Standard error = $0.28

Hence, Option (c) is the correct option.

9. What's the least common multiple (LCM) of 2, 6, and 8?

algol [13]

Answer:

Step-by-step explanation:

The LCM or least common multiple of these numbers is 24

To get 24, you list all the multiple of these numbers until they all share at least one

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24

6, 12, 18, 24

8, 16, 24

They all share 24 so this is the LCM

Hope this helps

Does anyone know how to solve this? It’s really starting to stress me out.

bekas [8.4K]

Answer:

π − 12

Step-by-step explanation:

lim(x→2) (sin(πx) + 8 − x³) / (x − 2)

If we substitute x = u + 2:

lim(u→0) (sin(π(u + 2)) + 8 − (u + 2)³) / ((u + 2) − 2)

lim(u→0) (sin(πu + 2π) + 8 − (u + 2)³) / u

Distribute the cube:

lim(u→0) (sin(πu + 2π) + 8 − (u³ + 6u² + 12u + 8)) / u

lim(u→0) (sin(πu + 2π) + 8 − u³ − 6u² − 12u − 8) / u

lim(u→0) (sin(πu + 2π) − u³ − 6u² − 12u) / u

Using angle sum formula:

lim(u→0) (sin(πu) cos(2π) + sin(2π) cos(πu) − u³ − 6u² − 12u) / u

lim(u→0) (sin(πu) − u³ − 6u² − 12u) / u

Divide:

lim(u→0) [ (sin(πu) / u) − u² − 6u − 12 ]

lim(u→0) (sin(πu) / u) + lim(u→0) (-u² − 6u − 12)

lim(u→0) (sin(πu) / u) − 12

Multiply and divide by π.

lim(u→0) (π sin(πu) / (πu)) − 12

π lim(u→0) (sin(πu) / (πu)) − 12

Use special identity, lim(x→0) ((sin x) / x ) = 1.

π (1) − 12

π − 12

What is the difference of 8 times a number r and 12?

lapo4ka [179]

Answer:

The difference of 8 times a number r and 12 is solved for a number r and is given by $r=\frac{3}{2}$

Step-by-step explanation:

Given problem is the difference of 8 times a number r and 12

It can be written as

$(8\times r)-12$

To simplify the above expression :

8r-12

$8r-12=0$

$8r-12+12=0+12$ ( using addition property of equality )

$8r=12$

$8r(\frac{1}{8})=12(\frac{1}{8})$ (using division property of equality )

$r=\frac{3}{2}$

Therefore $r=\frac{3}{2}$

Therefore the difference of 8 times a number r and 12 is solved for a number r and is given by $r=\frac{3}{2}$
