Answer:

Population in 1950 was 4,100,000

Step-by-step explanation:

Equation: 5x + 2,000,000 = 22,500,000

Subtract 2,000,000 from each side: 5x = 20,500,000

Divide each side by 5: x = 4,100,000

I hope this helps, please mark Brainliest, thank you!

What is the factored form of _________?
enyata [817]

Answer:

C

Step-by-step explanation:

The expression given is a difference of cubes and factors as

a³ - b³ = (a - b)(a² + ab + b²)

8x^{24} = (2x^{8})³ ⇒ a = 2x^{8}

27y^{6} = (3y²)³ ⇒ b = 3y²

Hence 2 factors are

(2x^{8} - 3y²) and

((2x^{8})² + (2x^{8} × 3y²) + (3y²)²)

= (4x^{16} + 6x^{8}y² + 9y^{4})

Hence the factored form of the expression is C

For f(x) = 2x + 3 and g(x) = x2 – 8, find (f + g)(x).
Nataly_w [17]

Answer:

x² + 2x - 5

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x)

= 2x + 3 + x² - 8 ← collect like terms

= x² + 2x - 5

A supervisor has determined that the average salary of the employees in his department is $40,000 with a standard deviation of $
mihalych1998 [28]

The z-score for 36,000 is (36,000 - 40,000) / (15,000 / √25) = -1.333

The z-score for 42,000 is (42,000 - 40,000) / (15,000 / √25) = 0.6667

P(36,000 < x < 42,000) = P(-1.3333 < z < 0.6667)

P(z < 0.6667) - P(z < -1.3333)

0.7475 - 0.0913

0.6562

Given: 18x-2(3x+1)=5x-16<br> Prove: x=-2
zlopas [31]

Answer:

True

Step-by-step explanation:

Evaluate 18 x - 2 (3 x + 1) = 5 x - 16 where x = -2:

-2×18 - 2 (1 - 2×3) = -2×5 - 16

3 (-2) = -6:

-2×18 - 2 (-6 + 1) = -2×5 - 16

1 - 6 = -5:

-2×18 - 2-5 = -2×5 - 16

18 (-2) = -36:

-36 - 2 (-5) = -2×5 - 16

-2 (-5) = 10:

10 - 36 = -2×5 - 16

5 (-2) = -10:

10 - 36 = -10 - 16

10 - 36 = -26:

-26 = -10 - 16

-10 - 16 = -26:

-26 = -26

-26 is equal to -26:

Answer:  True
