what is the difference between -(4) to the power of 7, (-4) to the power of 7, -4 to the power of 7, help i'm lost and my teache

kogti [31]

For -(4)^7
the - is not affected by the power of 7

For (-4)to the power of7 is the same as -4 to the power of 7

It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7

But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4

I am not good at English if there is any things that you feel confused you may ask

Vending machines can be adjusted to reject coins above and below certain weights. The weights of legal U.S. quarters have a norm

tigry1 [53]

Answer: The percentage of legal quarters will be rejected by the vending machine = 2.275%

Step-by-step explanation:

Given: The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram.

Let x be the weights of legal U.S. quarters .

Required probability: $P(x5.81)$

$=P(\dfrac{x-\mu}{\sigma}\dfrac{5.81-5.67}{0.07})\\\\=P(z2)\approx0.02275 \ \ \ [By\ P-value\ calculator]$

The percentage of legal quarters will be rejected by the vending machine = 2.275%
