If you want to factor -2 out of -6x + 10, simply divide everything by -2 and put the result in a parentheses times -2:

(-6x + 10)/-2 = 3x - 5

Therefore, the factored form would be -2(3x - 5).

If you want to check the answer, just redistribute the -2:

-2 * 3x = -6x and -2 * -5 = 10

-6x + 10 <----- It checks out

Hope this helps! :)

According to the National Telecommunication and Information Administration, 56.5% of U.S. households owned a computer in 2001. W

Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Assuming a binomial distribution for the number of U.S. households that owned a computer in 2001. The formula for binomial distribution is expressed as

P(X = r) = nCr × q^(n - r) × p^r

Where

p = probability of success

q = probability of failure

n = number of sample

From the information given,

p = 56.5% = 56.5/190 = 0.565

q = 1 - p = 1 - 0.565 = 0.435

n = 3

We want to determine P(x greater than or equal to 1). This is also expressed as

1 - P(x lesser than or equal to 1)

P(x lesser than or equal to 1) = P(x = 0) + P(x =1)

P(x = 0) = 3C0 × 0.435^(3 - 0) × 0.565^0 = 0.082

P(x = 1) = 3C1 × 0.435^(3 - 1) × 0.565^1 = 0.32

P(x greater than or equal to 1) = 0.082 + 0.32 = 0.402

Dy/dx of y=sin3xcos2x?

tatuchka [14]

Answer:

dy/dx = d/dx (sin3x.cos2x)

dy/dx = cos3x . 3 . -sin2x . 2 (Using chain rule)

dy/dx = -6cos3xsin2x

GO.o has 3 orange picks for every 2 green. If there are 25 picks in all, how many picks are orange?

Reika [66]

Given

GO.o has 3 orange picks for every 2 green

there are 25 picks in all

Find out how many picks are orange.

To proof

As given in question

GO.o has 3 orange picks for every 2 green

i.e the ratio of orange to every green becomes

$\frac{Orange}{Green}:\frac{3}{2}$

total number of picks = 25

let the GO.o pick of 3 orange picks for every 2 green =x

than the equation becomes

3x + 2x = 25

5x = 25

x = 5

Than

the number of oranges = 3x

putting the value of x

= 15

the number of green = 2x

= 10

thus the 15 picks are orange.

Hence proved

Answer:

A. Cylinder + cone

Volume is the sum of volumes:

V = Vcon + Vcyl = 1/3πr²h₁ + πr²h₂
V = 1/3π*9²*12 + π*9²*120 = 31554.2 cm³

Surface area of cone:

A = A=πr(r+√(h₁²+r²)) = π*9(9 + √(9²+12²)) = 678.6 cm²

Surface area of cylinder minus bases:

A = 2πrh₂ = 2π*9*120 = 6785.8 cm²

Total surface area:

678.6 + 6785.8 = 7464.4 cm²

-------------------------------------------------

B. Cube+ pyramid

Volume:

V = a³ + (1/3)a²h = a³ + (1/3)a²√(l²-(a/2)²)
V = 8³ + (1/3)8²√(10²-4²) = 707.5 cm³

Surface area of pyramid:

A = a² + 2al = 8² + 2*8*10 = 224 cm²

Surface area of cube minus bases:

A = 4a² = 4(8²) = 256 cm²

Total surface area:

A = 224 + 256 = 480 cm²
