What percent of 95 is 74

Softa [21]

74 is what percent of 95?

74 is P% of 95

Equation: Y = P% * X

Solving our equation for P

P% = Y/X

P% = 74/95

p = 0.7789

Convert decimal to percent:

P% = 0.7789 * 100 = 77.89%

What is the equation of the trend line? Enter your answers in the boxes. K = _J +_

MrRissso [65]

The y-intercept of the trend line is (0,28). The slope of this line is
28-0
m = --------- = 2
14-0

Thus, the equation of the trend line, in variables K and J, is

K = 2J + 28

Simplify

melomori [17]

Answer: $4\sqrt{3}$

Step-by-step explanation:

For this exercise it is important to remember the following:

$i=\sqrt{-1} \\\\i^2=-1$

Given the following expression:

$-2i\sqrt{-12}$

You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:

1. Replace $\sqrt{-1}$ with $i$ and simplify:

$(-2i)(i)\sqrt{12}=-2i^2\sqrt{12}=-2(-1)\sqrt{12}=2\sqrt{12}$

2. Descompose 12 into its prime factors:

$12=2*2*3=2^2*3$

3. Substitute into the expression:

$=2\sqrt{2^2*3}$

4. Since $\sqrt[n]{a^n}=a$ , you can simplify it:

$=(2)(2)\sqrt{3}=4\sqrt{3}$

Suppose the null hypothesis is not rejected. State the conclusion based on the results of the test. Three years ago, the mean p

Likurg_2 [28]

Answer:

A. There is not sufficient evidence to conclude that the mean price of a single-family home has decreased

Step-by-step explanation:

To study : Whether the mean price of single family home has decreased or not -

Null Hypothesis [H0] = There is no change in mean price of single family home

Alternate Hypothesis [H1] = There is change (decrease) in mean price of single family home

If the null hypothesis is not rejected, it implies that 'there is no change in mean price of single family home' has been statistically accepted.

So, it states that - There is not sufficient evidence to conclude that the mean price of a single-family home has decreased

what's the difference between (-4)^-3 and -4^-3. basically what's the difference when there's parenthesis for the base number?

NNADVOKAT [17]

(-4)^-3 = $\frac{1}{-64} or -0.015625$
-4^-3 = $\frac{1}{-64} or -0.015625$

Basically in this situation there is no difference whether parenthesis are used or not.
