Simplify brackets

5y+2+14x=5y+2+14x5y+2+14x=5y+2+14x
Since both sides equal, there are infinitely many solutions
Infinitely Many Solutions

SO BASICALLY THAT MEANS IT EQUALS TO 0.

Simplifying (5y + 2) + 14x = 5y + (2 + 14x) Reorder the terms: (2 + 5y) + 14x = 5y + (2 + 14x) Remove parenthesis around (2 + 5y) 2 + 5y + 14x = 5y + (2 + 14x) Reorder the terms: 2 + 14x + 5y = 5y + (2 + 14x) Remove parenthesis around (2 + 14x) 2 + 14x + 5y = 5y + 2 + 14x Reorder the terms: 2 + 14x + 5y = 2 + 14x + 5y Add '-2' to each side of the equation. 2 + 14x + -2 + 5y = 2 + 14x + -2 + 5y Reorder the terms: 2 + -2 + 14x + 5y = 2 + 14x + -2 + 5y Combine like terms: 2 + -2 = 0 0 + 14x + 5y = 2 + 14x + -2 + 5y 14x + 5y = 2 + 14x + -2 + 5y Reorder the terms: 14x + 5y = 2 + -2 + 14x + 5y Combine like terms: 2 + -2 = 0 14x + 5y = 0 + 14x + 5y 14x + 5y = 14x + 5y Add '-14x' to each side of the equation. 14x + -14x + 5y = 14x + -14x + 5y Combine like terms: 14x + -14x = 0 0 + 5y = 14x + -14x + 5y 5y = 14x + -14x + 5y Combine like terms: 14x + -14x = 0 5y = 0 + 5y 5y = 5y Add '-5y' to each side of the equation. 5y + -5y = 5y + -5y Combine like terms: 5y + -5y = 0 0 = 5y + -5y Combine like terms: 5y + -5y = 0 0 = 0 Solving 0 = 0 Couldn't find a variable to solve for.

DanielleElmas [232]

Answer:

Step-by-step explanation:

Start with why C isn't the answer.

y = 1.8^0 . The power is zero. Anything to the zero power (anything except 0 to the 0 power) is 1. So 1.8^0 is 1 not something else. C assumes that somehow 0,1.8 turns into 1.8. It does not. The second part is also wrong but you don't need it. However here it is.

x = 0 y = 3

x = 1 y = 3 * 1.8 = 5.4

x = 2 y = 3 * 1.8^2 = 3*3.24 = 9.72

You should be able to see that if you multiply 5.4 by 3, you don't get 9.72

C just does not work.

=======

The actual answer is A. That's exactly what the graph does. If you multiply 5.4 * 1.8 you should get 9.72. Just for completeness, I've included the graph.

natali 33 [55]

Answer:

98% confidence interval: (29.25,38.87)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 34.06

Sample size, n = 134

Sample standard deviation, s = 23.83

a) 98% confidence interval

$\bar{x} \pm z_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.02} = \pm 2.33$

$34.06 \pm 2.33(\frac{23.83}{\sqrt{133}} ) = 34.06 \pm 4.81 = (29.25,38.87)$

b) If a 95% confidence interval were constructed with these data, confidence interval would be narrower as the confidence level is decreasing as compared to 98%

c) If a sample of 150 students had been studied, the width of confidence interval will decrease as the sample size increases.
