Answer:

Infinite Solutions/Many solutions

Step-by-step explanation:

Use PEMDAS.  P=parenthesis.  5(x-x).  x-x=0, and 0 multiplied by any number is ALWAYS zero.

2x+2x is 4x

Since 4x=4x no matter what x is, there is an infinite set of solutions

yanalaym [24]

Answer: 0.05

Step-by-step explanation:

  • Sampling error is the error occurs by considering sample for study instead of entire population.

Given : The proportion of items in a population that possess a specific attribute is known to be 0.45.

Sample size : n= 100

Sample proportion of items in a population that possess a specific attribute : \hat{p}=0.48

Now, the formula to find the sampling error :

\text{Sampling error} =\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

\text{Sampling error} =\sqrt{\dfrac{0.48(1-0.48)}{100}}

=\sqrt{\dfrac{0.48(0.52)}{100}}\\\\=\sqrt{0.002496}\approx0.05

Hence, the sampling​ error =0.05

Which congruence theorem can be used to prove △WXZ ≅ △YZX?
Svetach [21]
Hi there!
The congruency theorem that proves these two triangles congruent is AAS. This is because both triangles have two congruent angles and the side comes from the side that can be proved congruent in both triangles by the reflexive property.
Hope this helps!! :)If there's anything else that I can help you with, please let me know!
