Answer:

a) y=650x+0

b) 24,000=650x

24,000/650=x

x=37

I hope this is good enough:

if you can you don't have to put the +0 its just to fill it all out

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally

saveliy_v [14]

Answer:

0.8029 = 80.29% probability that the thickness is between 3.0 and 7.0 mm.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 4.6 millimeters (mm) and a standard deviation of 1.5 mm.

This means that $\mu = 4.6, \sigma = 1.5$

Find the probability that the thickness is between 3.0 and 7.0 mm.

This is the pvalue of Z when X = 7 subtracted by the pvalue of Z when X = 3. So

X = 7

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

$Z = \frac{7 - 4.6}{1.5}$

$Z = 1.6$

$Z = 1.6$ has a pvalue of 0.9452

X = 3

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

$Z = \frac{3 - 4.6}{1.5}$

$Z = -1.07$

$Z = -1.07$ has a pvalue of 0.1423

0.9452 - 0.1423 = 0.8029

0.8029 = 80.29% probability that the thickness is between 3.0 and 7.0 mm.

Diagonal of the left triangle = ((8)^2+(7)^2)^0.5= (113)^0.5
x =( 12^2 -(113)^0.5)^2))^0.5=( 144- 113)^0.5= (31)^0.5= 5.57

For ur working, ur mistake lies in the line : x^2+12^2=10.6^2
It shld be 12^2= x^2+10.6^2

Alex73 [517]

Answer: 30% chose watermelons.

Step-by-step explanation:

if 29% chose apples and 41% chose bananas, that equals 70%

So, out of 100%, 70% chose both apples and bananas, which leaves 30% for watermelons.
