Answer:

950 km

Step-by-step explanation:

$\frac{1}{250} = \frac{3.8}{x}$

(cross multiply)

250(3.8)= 950

(divide both sides by 1)

950/1=950

Answer:

0.1384

Step-by-step explanation:

Using binomial probability:

P = nCr p^r q^(n-r)

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1-p).

Given n = 25, r = 4, p = 0.10, and q = 0.90:

P = ₂₅C₄ (0.10)⁴ (0.90)²⁵⁻⁴

P = 12650 (0.10)⁴ (0.90)²¹

P = 0.1384

Which expression is a difference of squares with a factor of 5x − 8?

Olegator [25]

Answer:

$25x^2-64$

Step-by-step explanation:

Remember that the formula for the difference of squares is $a^2-b^2=(a+b)(a-b)$ . The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:

$(5x-8)(5x+8)=(5x)^2-8^2$

$(5x-8)(5x+8)=5^2x^2-64$

$(5x-8)(5x+8)=25x^2-64$

We can conclude that the correct answer is $25x^2-64$ .
