What is −(8−1+5)?<br> Written explanation.

Dmitriy789 [7]

Step-by-step explanation:

You can use the distributive property

-(a - b + c) = -a + b - c

So, the answer to this is -8 + 1 - 5.

First you want to subtract 36

so it looks like this $\sqrt[4] {(4x+164)^3}=64$

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

${(4x+164)^3}=64^4$ which is equal to ${(4x+164)^3}=16777216$

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23

Part E

Effectus [21]

The mean, median, standard deviation, and interquartile range for each data set is given below.

<h3>What is the definition of Interquartile Range (IQR)?</h3>

When arranged from lowest to highest, the IQR represents the central 50% of values.

Find the median (middle value) of the lower and higher half of the data to get the interquartile range (IQR).

These are the quartile 1 (Q1) and quartile 3 (Q3) values (Q3). The difference between Q3 and Q1 is the IQR.

<h3>What are the measures of central tendency for Manuels Data?</h3>

Using the statistical tool, the following were arrived at:

Standard Deviation = 3.13961
Mean = 8
Median = 8
IQR = Q3-Q1 = 10 - 6 = 4

<h3>What are the measures of central tendency for Grethcen's Data?</h3>

Using the statistical tool, the following were arrived at:

Standard Deviation = 4.68737.
Mean = 9.6
Median = 9
IQR = IQR = Q3-Q1 = 12 - 7 = 5.

See the respective Histograms attached.

A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviat

n200080 [17]

bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm

<u>Step-by-step explanation:</u>

Here we have , A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 13 cm with a standard deviation of 0.10 cm. We need to find For what lengths will a bolt be destroyed .Let's find out:

A manufacturer of bolts has a quality control policy that requires it destroy any bolts that are more than 2 standard deviations from the mean.

mean length= $13 cm$

standard deviation= $0.10 cm$

2 standard deviation from mean= $13 \pm (2(0.10))$

Therefore, bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm
