Answer:

cos M = 38 / 63

Step-by-step explanation:

SOH - CAH - TOA

is how I remember the calculations,

S - sin

C - cos

T - tan

(o = opposite side ; a = adjacent side ; h = hypotenuse)

SOH would be sin = opposite/hypotenuse

CAH means cos = adjacent / hypotenuse

Okay, so looking at the angle M, we know the hypotenuse [63] and the adjacent value [38]

From this, (only having H and A), we can only find the cos of M

(without finding additional numbers, which we could do with the Pythagorean theorem)

So, the cos of M is adjacent/hypotenuse

cos M = 38 / 63

(I didn't try to find other measurements of the triangle here because the most simple measurements [that were already there] worked/was an option)

Evaluate 32 + 12 = ( 6 – 3) x 8.

Brrunno [24]

Hello there!

(Equation #1) 32 + 12 = 44

(Equation #2) 6 - 3 = 3, 3 x 8 = 24

These both equations don't have the same answer, even though it says that they are equal with each other, if you could correct these these 2 equations I am willing to answer again.

Hope this helped!!

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

sasho [114]

Answer:

a) $P(X$

$P(z$

b) $P(X>7.0)=P(\frac{X-\mu}{\sigma}>\frac{7-\mu}{\sigma})=P(Z1.47)$

$P(z>1.47)=1-P(z$

c) $P(3$

$P(-0.882$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Part a

Let X the random variable that represent the thickness of a population, and for this case we know the distribution for X is given by:

$X \sim N(4.5,1.7)$
