Answer:

Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.

A politician claims that 20% of the millions of votes cast for his opponent are fraudulent. To test this claim, an investigator

Elis [28]

Answer:

"0.0125" is the right solution.

Step-by-step explanation:

The given values are:

Random sample,

n = 90

Claims,

p = 20%

or,

= 0.20

By using normal approximation, we get

⇒ $\mu = np$

On substituting the values, we get

⇒ $=90\times 0.20$

⇒ $=18$

Now,

The standard deviation will be:

⇒ $\sigma=\sqrt{np(1-p)}$

On putting the above given values, we get

⇒ $=\sqrt{90\times 0.20\times (1-0.20)}$

⇒ $=\sqrt{18\times 0.8}$

⇒ $=\sqrt{14.4}$

⇒ $=3.7947$

hence,

By using the continuity correction or the z-table, we get

⇒ $P(x < 10) = P(x < 9.5)$

⇒ $P(x < 10) = P(\frac{x-\mu}{\sigma} -\frac{9.5-18}{3.7947} )$

⇒ $P(x < 10) = P(Z < -2.24)$

From table,

⇒ $P(x < 10) = 0.0125$

The side of a square measures 2x^2y^3 what is the area of the square if x=-2 and y=2

valentina_108 [34]

Here is your answer

4096  $({units})^{2}$

REASON:

Given, x= -2 and y= 2

Measure of each side of square=

$2 {x}^{2} × {y}^{3}$

Putting the values of x and y in above relation, we get

Side of square

$= 2 \times({ - 2})^{2} \times ({2}^{3})$

$= 2 \times 4 \times 8$

$= 64 \: units$

Now,

area of square= $({side})^{2}$

$= {64}^{2} {units}^{2}$

$4096 \: {units}^{2}$

image that you're doing an experiment to determine h9w the running speed of a hamster depends on the weight of the hamster. when

stepan [7]

In this experiment the independent variable, the one the experimenter varies, is the weight of the hamster.

The dependent variable, the one the experimenter observes, is the running speed of the hamster.

We usually use the x axis for the independent variable and the y axis for the dependent variable.

Answer: running speed
