Answer:

10:18

Step-by-step explanation:

when you multiply both of the ratios of paint by 2 you get 10 and 18 which makes the same shade if green paint because the ratio is just 2 times more if the original ratio (9:5)

An irrational number between -2 and -1<br><br> a rational number between -2 and -1
leva [86]

Answer:

An irrational number between -2 and -1 would be \frac{-\pi }{2}

A rational number between -2 and -1 would be -1.5

Step-by-step explanation:

\frac{-\pi }{2} = -1.570796... This number does not have repeating decimals, patterns, and it isn't a terminating decimal. It is irrational.

-1.5 is a terminating decimal, therefore it is rational, as well as between -2 and -1.

When studying radioactive material, a nuclear engineer found that over 365 days,
Gnom [1K]

Answer:

a) The mean number of radioactive atoms that decay per day is 81.485.

b) 0% probability that on a given day, 50 radioactive atoms decayed.

Step-by-step explanation:

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\lambda}*\lambda^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\lambda is the mean in the given interval.

a. Find the mean number of radioactive atoms that decayed in a day.

29,742 atoms decayed during 365 days, which means that:

\lambda = \frac{29742}{365} = 81.485

The mean number of radioactive atoms that decay per day is 81.485.

b. Find the probability that on a given day, 50 radioactive atoms decayed.

This is P(X = 50). So

P(X = 50) = \frac{e^{-81.485}*(81.485)^{50}}{(50)!} = 0

0% probability that on a given day, 50 radioactive atoms decayed.

Solve the system of equations.<br> 7x+10y=36<br> y=2x+9<br><br> x = ______<br><br> y = ______
wel

Step-by-step explanation:

Substitute the y in the 1st equation with the 2nd equation.

7x + 10(2x + 9) = 36

7x + 20x + 90 = 36

27x + 90 = 36

3x + 10 = 4

3x = -6

x = -2

So now we can find y.

y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.

So x = -2, y = 5.

What is the distance from the point (3,8) to the point (7,-6)?
oksano4ka [1.4K]

Answer: Distance is 14.6

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

(x2-x1) = (7 - 3) = 4

(y2-y1) = (-6 - 8) = -14

add it all together

(4)2 + (-14)2 = 16 + 196 = 212

Square 212

\sqrt{212} =14.5602

round to the nearest tenth

=14.6
