Ummmmm lets see.... 1? Because then 3 times 1 is 3 + 3 = 9 so that's the only answer that works

3(x)+3-9=?
? = 0

3 + 3 = 6 we have to subtract 3x from 6
So,  3(x) - 6 

3 - 3 = 0
3 = 0

6 ÷ 3 = 2
So, x - 2 = 0

x + 2 = x
0 + 2 = 2

One Solution was found in this problem,
so x = 2

The legs of a isosceles right triangle both measure 10 inches find the length of the hypotenuse
Artist 52 [7]

Answer:

Hypotenuse = 14.1421 inches (rounded off to four decimal values)

Step-by-step explanation:

The legs of an isosceles triangle both measure 10 inches

Since the triangle is a right triangle,

We apply the Pythagorean Theorem to find the height of the hypotenuse

a² + b² = c²

a = 10 inches, b = 10 inches and (c) is the hypotenuse whose value we don't know.

So; 10² + 10² = c²

c² = 100 + 100

c² = 200

c = \sqrt{200} = 14.1421356237 inches

The hypotenuse is 14.1421 inches (answer rounded off to four decimal values)

It is known that 5% of the population over the age of 30 in a city is a university graduate. Among the 100 people chosen randoml
Novosadov [1.4K]

Answer:

A) 1/3200000

B) 19/20

Step-by-step explanation:

Percentage population of graduates = 5

Proportion of graduates from 100 random samples = percentage × number of samples

Proportion of graduates = 0.05 × 100 = 5

Probability of having 5 graduates among the 100 random samples:

P(1 graduate) = possible outcome / total required outcome

P(1 graduate) = (5 / 100) = 1/20

P(5 graduates) = (1/20)^5

P(5 graduates) = 1/3200000

Probability of never being a graduate = (1 - probability of being a graduate)

Probability of never being a graduate = ( 1 - (1/20)) = 19/20
