1) Let's evaluate that expression
3x+5
2) Since the value of x has been given, then let's plug that into the expression
3x+5
3(5) +5
15 +5
20
3) The answer is 20
Using combination and permutation we found out that there are 30240 ways to make varieties of pizza with 3 toppings.
Given 10 toppings
10C3 =10!/3! 7! =120
10P5 =10!/5! =30240 ways
A permutation is a process of placing objects or numbers in order. Combining is the ability to select an object or number from a group of objects or collections such that the order of the objects does not matter.
In mathematics, a combination is the selection of elements from a set with different members, so the order of selection does not matter.
The process or state of binding. Some combination: A combination of ideas. Combined: A chord is a combination of notes. Alliance of Individuals or Parties: Combinations to restrict transactions.

Answer:
Result is statistically significant.
Step-by-step explanation:
Given that :
Chisquare statistic, χ² = 67.81
Critical value for the distribution, χ²critical = 3.84
α = 0.05
The Decison region :
If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.
Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05
It would be -140=x... to get this you would multiply x over 14 by 14... since you did it to one side then you have to do it to the other
Answer:
Step-by-step explanation:
<u>Given relationships:</u>
DE = 2 AC
- Incorrect. Should be DE = 1/2 AC
DE║AC
m∠BCA = 2(m∠BED)
- Incorrect. Should be m∠BCA = m∠BED
DE = AC
- Incorrect. Should be DE = 1/2 AC
