Answer:
1. has a common factor of 2
2. has a common dividend of 2
3. has a common difference of -10
Number patterns 1 and 2 are geometric sequences so that is why they contain a common factor or dividend
Number pattern 3 is an arithmetic sequence which is why it has a common difference (substracting instead of multiplying or dividing like the first two)
Hope this helps!
You would do 1/4 x 1/2 to get 1/8 of a pound.
Answer:
31 in²
Step-by-step explanation:
Take the area of the square, and subtract the area of the circle..
The area of the square is A = 12(12) = 144 in²
The radius of the circle is 6 in, so
The area of the circle is A = π(6²) = 36π
The area between the square and the circle is
144 - 36π
144 - 36(3.14)
30.90266447
31 (rounded to the nearest whole number)
Answer: Null hypothesis = ![H_0:p=0.74](https://tex.z-dn.net/?f=H_0%3Ap%3D0.74)
Alternative hypothesis = ![H_1:p\neq0.24](https://tex.z-dn.net/?f=H_1%3Ap%5Cneq0.24)
Step-by-step explanation:
Given claim : 74% of workers got their job through college.
In proportion , 0.74 of workers got their job through college.
Let p be the proportion of workers got their job through college.
Then claim : ![p=0.74](https://tex.z-dn.net/?f=p%3D0.74)
We know that the null hypothesis always takes equality sign and alternative hypothesis takes just opposite of the null hypothesis.
Thus, Null hypothesis = ![H_0:p=0.74](https://tex.z-dn.net/?f=H_0%3Ap%3D0.74)
Alternative hypothesis = ![H_1:p\neq0.24](https://tex.z-dn.net/?f=H_1%3Ap%5Cneq0.24)
Answer:
Using mental math, the approximate tip to leave for a bill of $81.79, if you tip 15% would be?
c.$12.30
Step-by-step explanation:
10% is $8.179, then 5% is a half of this sum, i.e. $8.179:2=$4.0895
3. 15%=10%+5% and in $ it is $8.179+$4.0895=$12.2685 that is nearly $12.30.
