A factor is considered a root when we substitute the number and the equation is equal to zero. In this case, we can substitute each factor to the given equation above and check whether the equation results to zero. There are no equations that result to zero. The answer should be x- 133^1/3. Answer is D

When Ryan counted some dimes and quarters he had 196 coins and a total of $39.40. How many coins of each kind does Ryan have?

Nonamiya [84]

Quarters = x
dimes = 196 - x

10(196 - x) + 25x = 3940
1960 - 10x +25x = 3940
1960 + 15x = 3940
15x = 1980
x = 132

169 - 132 = 64

Therefor there are 132 quarters and 64 dimes

What is the difference in solving functions when giving the following information: f(x)=2 and f(2)

vfiekz [6]

*Remember that y and f(x) are the same.

With f(2), you are solving for the output (y), given that the input (x) is equal to 2.

With f(x) = 2, you are solving for the input (x), given that the output (y) is equal to 2.

7.1.13 Question Help Use the sample data and confidence level given below to complete parts (a) through (d). A research institut

r-ruslan [8.4K]

Answer:

The Point estimate of the Population proportion E = 0.039≅0.04

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 992

and x = 570

The Population proportion

$p = \frac{x}{n} = \frac{570}{992} = 0.5745$

Step(ii):-

The point estimate of the Population proportion is determined by

$E = 2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }$

E = 0.039≅0.04

Final answer:-

The point estimate of the Population proportion E = 0.039≅0.04
