(n-6)/(n-7)=9/2
-> 2(n-6)=9(n-7)
-> 2n-12=9n-63
-> 2n-9n=-63+12
-> -7n = -51
-> n = 51/7

The answer is n=51/7

What do I need to subtract from to get angle two?

ololo11 [35]

Step 1) Add up the three given angles: 125+109+83 = 317

Step 2) Subtract the result (found in step one) from 360
360 - 317 = 43

The reason for the 360 is because for any four-sided polygon, the angles always add up to 360 degrees.

The answer is 43

I need answers for all! thank you will mark brainlist!! please help me i’m begging you <3

Darina [25.2K]

Step-by-step explanation:

y = 2/5 x - 9/5

when x = -1,

the value of y = 2/5(-1) - 9/5

= -2/5 - 9/5 = -11/5

when x = 0

=> y = 2/5(0) -9/5

= 0-9/5 = -9/5

when x=1

=> y = 2/5(1) - 9/5

= 2/5 - 9/5 = 7/5

The number of orders received daily by an online vendor of used CDs is normally distributed with mean 270 and standard deviation

frez [133]

Answer:

Step-by-step explanation:

Given that the number of orders received daily by an online vendor of used CDs (say X) is normally distributed with mean 270 and standard deviation 16.

X is N(270, 16)

To find percentage of days will the company have to hire extra help or pay overtime, we can find probability using std normal table

X>302 means

$Z>\frac{302-270}{16} =2$

P(Z>2) = 0.25

Thus 25% of days will the company have to hire extra help or pay overtime
