2 answers:

5 0

1.Multiply both sides by 3
x−9=2×3
2. Simplify 2×3 to 6
x−9=6
3. Add 9 to both sides
x=6+9
4.Simplify 6+9 to 15
answer is x=15

To find (x-9)/3=2, we do
(x-9)/3=2
(x-9)/3×3=2×3
x-9=6
x-9+9=6+9
x=15
So, x is 15

Witch is greater 4 meters or 450 centimeters

Darya [45]

Well, 1 meter is equal to 100 centimeters.
Therefore, 4 meters is equal to 400 centimeters.

400 centimeters is less than 450 centimeters, so 450 centimeters is larger.

If the probability of being hospitalized during a year is 0.15 find the probability that no one in the family of 4 will be hospi

Goryan [66]

The probability that no one in the family of 4 will be hospitalized during a year is 0.52

Step-by-step explanation:

The probability for a person to be hospitalized during one year is

$p(h)=0.15$

As a consequence, the probability for a person of NOT being hospitalized during one year is

$p(h^{-1})=1-0.15=0.85$

If we have 4 people in the family, the probability of each of them of NOT being hospitalized during the year is independent from the probability of the others - therefore, these are independent events. This means that the total probability of the 4 people of not being hospitalized during a year is:

$p(h^{-1})^4=(0.85)^4=0.52$

So, the probability that no one in the family of 4 will be hospitalized during a year is 0.52.

Explain why an inverse variation function is not the best model for the data set

dmitriy555 [2]

Answer: The cause of exponential decay. Sowwy if im wrong

Step-by-step explanation:

An inverse variation function is not the best model because the data points show an exponential decay. The fact that this is true for ALL of the points shown indicates we have an inverse variation of the form x*y = k where k = 60 in this case. ... For any inverse variation, as x increases, y will decrease (and vice versa).

Find four distinct complex numbers (which are neither purely imaginary nor purely real) such that each has an absolute value of

Luda [366]

Answer:

0.5 + 2.985i
1 + 2.828i
1.5 + 2.598i
2 + 2.236i

Explanation:

Complex numbers have the general form a + bi, where a is the real part and b is the imaginary part.

Since, the numbers are neither purely imaginary nor purely real a ≠ 0 and b ≠ 0.

The absolute value of a complex number is its distance to the origin (0,0), so you use Pythagorean theorem to calculate the absolute value. Calling it |C|, that is:
