Answer:

n^2 -10n + 24

Step-by-step explanation:

Given expression:

(n-6)(n-4)

Solution:

Apply distributive property,then simplifying using PEMDAS,we obtain

n^2 - 4n - 6n + 24
n^2 -10n +24

Hence,n^2 -10n -24 is the answer.

Find the value of x in the Parallelogram

x=127 that is because a rectangle equals 365 degrees and two sides have to be parallel so 53+53=106 and 365-106=254 and 254/2=127

Assume the readings on thermometers are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degrees

lozanna [386]

Answer: 0.0035

Step-by-step explanation:

Given : The readings on thermometers are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degrees C.

i.e. $\mu=0$ and $\sigma= 1$

Let x denotes the readings on thermometers.

Then, the probability that a randomly selected thermometer reads greater than 2.17 will be :_

$P(X>2.7)=1-P(\xleq2.7)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{2.7-0}{1})\\\\=1-P(z\leq2.7)\ \ [\because\ z=\dfrac{x-\mu}{\sigma}]\\\\=1-0.9965\ \ [\text{By z-table}]\ \\\\=0.0035$

Hence, the probability that a randomly selected thermometer reads greater than 2.17 = 0.0035
