I didn’t pay attention in class help
Alona [7]

Answer:

The 1/4th power means the 4th root of a number.

Therefore for the first question, the answer should be 4th root of 1296 -4th root of 625. or \sqrt[4]{1296}

4

1296

-\sqrt[4]{625}

4

625

:D

For the second question just calculate? what to the 4th power is 1296 and what to the 4th power is 625?

They should respectively be 6 and 5. So the final answers we get is 6-5=1

If you have any questions about this just ask me in the comment and I will get to it as soon as I could.

hopecthis helps

Some IQ tests are standardized to a Normal model N(100,19). What is the cutoff value for the top 5% of all IQs
Montano1993 [528]

Answer:

The cutoff value for the top 5% of all IQs is 131.255.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 100, \sigma = 19

What is the cutoff value for the top 5% of all IQs

This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.

Z = \frac{X - \mu}{\sigma}

1.645 = \frac{X - 100}{19}

X - 100 = 19*1.645

X = 131.255

The cutoff value for the top 5% of all IQs is 131.255.

3over 7 = blank over 35
iragen [17]

Let blank be x

\\ \sf\longmapsto \dfrac{3}{7}=\dfrac{x}{35}

\\ \sf\longmapsto 7x=35(3)=105

\\ \sf\longmapsto x=\dfrac{105}{7}

\\ \sf\longmapsto x=15
