Shannon did not mix the correct shade. Cause the correct ratio of blue and red is 7:5. While Shannon mix 12:8=3:2 which is not equal to 7:5.
Answer:
12.5
Step-by-step explanation:
4.5 - 3 = 1.5, so 11 + 1.5 = 12.5
The way to find the factores is by seeking the polonomial's roots, or zeros!
To find the roots, we set the polinomial equation to zero:
x^2+16y^2=0
Then we solve this equation:
x^2=-16y^2
This is only true, if x=y=0.
Answer: Third Option
![x=1.469743](https://tex.z-dn.net/?f=x%3D1.469743)
Step-by-step explanation:
We have the following exponential equation
![3^{x+1}=15](https://tex.z-dn.net/?f=3%5E%7Bx%2B1%7D%3D15)
We must solve the equation for the variable x
To clear the variable x apply the
function on both sides of the equation
![log_3(3^{x+1})=log_3(15)](https://tex.z-dn.net/?f=log_3%283%5E%7Bx%2B1%7D%29%3Dlog_3%2815%29)
Simplifying we get the following:
![x+1=log_3(15)](https://tex.z-dn.net/?f=x%2B1%3Dlog_3%2815%29)
To simplify the expression
we apply the base change property
![log_b(y)=\frac{log(y)}{log(b)}](https://tex.z-dn.net/?f=log_b%28y%29%3D%5Cfrac%7Blog%28y%29%7D%7Blog%28b%29%7D)
This means that:
![log_3 (15)=\frac{log(15)}{log(3)}](https://tex.z-dn.net/?f=log_3%20%2815%29%3D%5Cfrac%7Blog%2815%29%7D%7Blog%283%29%7D)
Then:
![x+1=\frac{log(15)}{log(3)}](https://tex.z-dn.net/?f=x%2B1%3D%5Cfrac%7Blog%2815%29%7D%7Blog%283%29%7D)
![x=\frac{log(15)}{log(3)}-1](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Blog%2815%29%7D%7Blog%283%29%7D-1)
![x=1.469743](https://tex.z-dn.net/?f=x%3D1.469743)
Answer:
1. Can be Paired or Not Paired
2. Paired
3. Not Paired
Step-by-step explanation:
Two sets of observations are paired if each observation in one set has a special correspondence or connection with exactly one observation in the other data set.
1. Can be Paired or Not paired
Reason -
We might look at testing the difference of means using a two sample t-test. However, we may also try running a paired t-test.
But its used in cases where the observations are usually from the same populations at different times or through different sources etc.
Hence can't conclude that it is paired or not paired.
2. Paired
Reason -
Each record is a price of the same item from different stores.
3. Not paired
Reason -
This is again a case of testing the difference of means of two-samples (2 independent samples precisely) that are not paired.
