Answer:

Step-by-step explanation:

Let's call the first number n. The next four numbers will be n + 3, n + 6, n + 9 and n + 12. Then, we have

n + n + 3 + n + 6 + n + 9 + n + 12 = 105

5n + 30 = 105

5n = 75

n = 15

The second smallest number is n + 3 which is 15 + 3 = 18.

Answer:

The 2003 scores have a higher coefficient of variation, so they are more dispersed

Step-by-step explanation:

We have to find the coefficient of variation(CV) for both these tests.

$CV = \frac{\sigma}{\mu}$

In which $\mu$ is the mean and $\sigma$ is the standard deviation.

Whoever has the higher CV has the higher variation, that is, is more dispersed.

2003

$\mu = 500, \sigma = 80$

$CV = \frac{\sigma}{\mu} = \frac{80}{500} = 0.16$

2004

$\mu = 560, \sigma = 84$

$CV = \frac{\sigma}{\mu} = \frac{84}{560} = 0.15$

The 2003 scores have a higher coefficient of variation, so they are more dispersed.

Help please

lyudmila [28]

Answer:

84

Step-by-step explanation:

Area of a rectangle : A = bh

5 x 6 = 30

Area of a trapezoid : A = 1/2 (b1 + b2) h

b1: 7 + 5 = 12

b2: 15

h: 10 - 6 = 4

12 + 15 = 27

27 x 4 x .5 = 54

Add the areas up:

30 + 54 = 84

Delvig [45]

Answer:

4x² + 6x + 2

Step-by-step explanation:

Solve by factoring.

4x · x = 4x²

4x · 1 = 4x

2x · 1 = 2x

2 · 1 = 2

Combine like terms.

4x² + 4x + 2x + 2

= 4x² + 6x + 2

Hope this helps.
