May anyone help me i have no idea

shtirl [24]

Answer:

No. GCF = 2

$2(x^2 - 5x + 10)$

$2(x^2 - 5x + 10)$ $(\dfrac{-5}{2})^2=(-2.5)^2 =6.25$

$2[x^2 - 5x+6.25-6.25 + 10]$

$2[(x^2 - 5x+6.25)-6.25 + 10]$

$2[(x - 2.5)^2-6.25+ 10]$

$2[(x - 2.5)^2+3.75]$

$2(x - 2.5)^2+7.5$

The scale of a map is 1:1,000,000. What are the real distances between two points if the distance between them on this map is: 1

snow_lady [41]

Answer:

Step-by-step explanation:

Scale= 1:1,000,000

Scaled distance = 1.8 dm

Actual distance = 1.8*1,000,000 = 1,800,000 dm

Find the standard deviation of the data set below. Round to the nearest tenth,<br> 6, 5, 2, 5,8

ASHA 777 [7]

Answer:

The standard deviation = 1.9

Step-by-step explanation:

standard deviation, ρ = sqrt ( $\frac{sum(x_{i} - u)^{2} }{N}$ )

Where u is the mean of the data, $x_{i}$ each given value, and N is the number of data given.

Mean, u = $\frac{6+5+2+5+8}{5}$

= 5.2

So that;

$(6-5.2)^{2}$ = $(0.8)^{2}$ = 0.64

$(5-5.2)^{2}$ = $(-0.2)^{2}$ = 0.04

$(2-5.2)^{2}$ = $(-3.2)^{2}$ = 10.24

$(5-5.2)^{2}$ = $(-0.2)^{2}$ = 0.04

$(8-5.2)^{2}$ = $(2.8)^{2}$ = 7.84

Sum = 18.8

So that;

$\sqrt{\frac{18.8}{5} }$ = $\sqrt{3.76}$

= 1.9391

= 1.9

The standard deviation of the given data is 1.9
