Answer: B data gathering
Step-by-step explanation:
all of those examples are examples of gathering data
Answer:
the appropriate operation count is 27 times longer than the original one.
Step-by-step explanation:
Given the data in the question;
let us consider the approximate operation count for the system of n₁ equation in n₁ unknowns as; ₁³ Or
O₁ = ₁³
so if the value of the unknowns is tripled i.e, n₂ = 3n₁,
the appropriate operation count will be;
O₂ = ₂³
= ³
= × 27 × n₁³
= 27( ₁³ )
O₂ = 27(O₁)
Therefore, the appropriate operation count is 27 times longer than the original one.
Answer: incomplete question
Find inverse
F(x)=5x-3/4
Ans: y/5+15/4=x
Step-by-step explanation: assuming f(x) to be y
Therefore y=5x-3/4
Y+3/4=5x
Dividing all through by 5 gives
Y/5+15/4=X
X/0.5 = 24
X/0.5(0.5) = 24(0.5)
X = 12
Answer: 20%
Step-by-step explanation: Since the number changes from 15 to 18, it's getting bigger which means it increases. To find the percent increase, we use the formula shown.
The amount of change is the difference between the two numbers. In this case, we would subtract 18 - 15 which equals 3. Then, we put 3 over our original number which is 15.
3 ÷ 15 = 0.2
Now, we need the percent increase which means we need to write 0.2 as a percent by moving the decimal point two places to the right to get 20%.
Therefore, the percent increase is 20%
