Answer:

Step-by-step explanation:

The inverse of the function would have the x-values and y-values swapped. To find the inverse of a function, the x('s) and the y('s) would be swapped. C is the only one with the x-values and the y-values swapped, and thus, is the correct answer.

I hope this helps. :)

Please help :((((((

Answer: c)

Step-by-step explanation:

This can be done through trial-and-error. Use the pythagoreas' theorem $a^{2} +b^{2} =c^{2}$ and if the left side of the equation is equal to the right, that is the answer.

(Do take note that c is the longest side.)

$0.07^{2} +2.4^{2} =5.7649$

$2.5^{2}=6.25$

Since $2.5^{2} \neq 5.7649$ , a) is wrong.

$17^{2} +30^{2} =1189\\
34^{2} =1156$

Since $34^{2}\neq1189$ , b) is wrong.

c) (answer)

$5^{2} +12^{2} =169\\13^{2} =169$

Since $13^{2} =169$ , c) is correct.

$(7x)^{2} +(12x)^{2} =193x^{2}\\(13x)^{2} =169x^{2}$

Since $(13x)^{2} \neq193x^{2}$ , d) is wrong.

Weights of the vegetables in a field are normally distributed. From a sample Carl Cornfield determines the mean weight of a box

pantera1 [17]

To find the z-score for a weight of 196 oz., use

$z=\frac{x-\mu}{\sigma}=\frac{196-180}{8}=\frac{16}{8}=2$

A table for the cumulative distribution function for the normal distribution (see picture) gives the area 0.9772 BELOW the z-score z = 2. Carl is wondering about the percentage of boxes with weights ABOVE z = 2. The total area under the normal curve is 1, so subtract .9772 from 1.0000.

1.0000 - .9772 = 0.0228, so about 2.3% of the boxes will weigh more than 196 oz.
