Which best describes the range of the function f(x)=2/3(6)x after it has been reflected over the x axis

2 answers:

4 0

The range is all real numbers.

The function given simplifies to just f(x) = 4x.

This is just a straight line that is increasing from left to right. If we reflect the line over the x-axis, it is still a line that goes on forever in each direction.

Therefore, the range will be all real numbers.

How many kernels of corn does it take to fill a 3-l soft drink bottle? (take that about four kernels fill 1 cm3 .)?

Art [367]

You need 12000 kernals. 1-liter is equal to (10cm)^3. If four kernels fill 1cm^3, it takes 4*1000 kernels to fill one liter. Therefore, to fill a 3-l soft drink bottle, it takes 3*4*1000=12000 kernels.

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,

⇒ $P(x < 10) = 0.0125$

6=68 and 8=112
This is Bc 1=112 and 1 and 4 are virtual angles so 4 would also equal 112. And 4 and 6 are supplementary angles, and supplementary angles always add up to 180, and since 4 is 112 you’d subtract 112 from 180 and you’d get 68, so 6=68 and 6 and 8 are also supplementary angles so 8 would be 112
