Answer:

Step-by-step explanation:
Area = L x W
5/9 = 2/3 * W
5/9 ÷ 2/3 = W
5/6 = W

22-j=
Step-by-step explanation:
Answer:
- The measure of ∠A is 66°.
Step-by-step explanation:
<u>We know that:</u>
- ∠A = 3x + 18
- ∠D = 4x + 2
- ∠D = ∠A
<u>Now, let's solve the equation. ∠D = ∠A.</u>
- => 3x + 18 = 4x + 2
- => -2 + 18 = x
- => 16 = x
<u>Now, let's substitute the value of x into any equation.</u>
- => 4x + 2
- => 4(16) + 2
- => <u>66°</u>
Hence, the measure of ∠A is 66°.
Decay rate for Radium-228 is 0.01205
Step-by-step explanation:
The half life of radium-228 is 5.75 years. We need to find the decay rate for radium.
The formula used is:

Where N₀ = amount of radioactive particles at time = 0
N_t = amount of radioactive particles are time (t)
λ = rate of decay constant
t = time
We are given half life so,
=0.5
t= 5.75 years
We need to find λ
Putting values in formula and solving:


So, Decay rate for Radium-228 is 0.01205.

The mean monthly rent and its standard deviation will be affected by the few students with a monthly rent of $1300. The mean would be significant without the outlliers.
To estimate or predict the expect rent of a student, it is best to choose the value from the middle. This gives a close estimate of the likely price of the rent without being affected by the extreme rent prices paid by few students.
Thus, we have interquartile range. It gives you a summary of the minimum, maximum, and average pricing from the data.
