Mathematics
1 answer:
Shtirlitz [24]3 years ago
7 0

Step-by-step explanation: I honestly am too lazy to solve but I will tell you what to do. For number 1-5 you need the amount (a) divided by the Tax/Tip/%off/Discount(d). Whatever that number is (t), you subtract that from a to get the total cost which is (c) So in other words - a-d=t a-t=c UWU

Then onto the next ones. Number 6: First you do 11/2800. Thats the 11%. Next you get 67,530 divide that by that last number you got. Then multiply that by 2800. Then there is your answer

Okay so next one Number 7: Same thing as the other one actually -v-

Next answer mate! Number 8: 3400 x4 + (3400/3.5) x 4= ???? You tell me that ;)

We almost doneeee Number 9: 20460 x 5 + (20460/5.5) x 5= ____ Hhehehehe last one mateyyyy

We actually at the last one. Its been fun helping you! :) Number 10: 35000/7 then whatever that is times 5. I enjoyed going back in my little kid brain tohelp you :)

One indicator of an outlier is that an observation is more than 2.5 standard deviations from the mean. Consider the data value 8
sergij07 [2.7K]

Answer:

a) No, since 80 is less than 2.5 standard deviations above the mean; b) Yes, since 80 is more than 2.5 standard deviations above the mean.

Step-by-step explanation:

For part a,

The mean is 70 and the standard deviation is 5.  This means that 2 standard deviations above the mean is 70+5+5 = 80.

This means that 80 is not an outlier, as it is not more than 2.5 standard deviations above the mean.

For part b,

The mean is 70 and the standard deviation is 3.  This means that 2 standard deviations above the mean is 70+3+3 = 76; 3 standard deviations above the mean is 70+3+3+3 = 79.  80 is more than this, so yes, it is an outlier.

Hi can someone help me with these 3 questions. Thanks :)
S_A_V [24]

Answer:

a) 45° cause tan = sin/cos and sin 45 and cos 45 both give square root 2/2

b) 120°

c) sin = -1/2 = -30° or 330° both are same

Use the trig circle which i have included in the answer to better understand trig angles

hope that answers your question

I want to let you know that each angle has sets of coordinates the left number is cos and right is sin. Ex) sin of 30 is 1/2 and cos of 30 is square root 3/2 In case you dont fully understand dont hesitate to comment.

good luck!!
