It would be 4/15 is greater.
4/15 = 26% wrong
3/10 = 30% wrong
2x+4.7=77.8
double the unknown number then add 4.7
Answer:
it's the 3rd one
Step-by-step explanation:
i used m ath way
A. Range=highest-lowest. 85-53=32
b. Mean=average. Add all of the numbers together then divide by 12, you get about 70.2
c. Median is the middle number, or average of middle 2 numbers. average of 63 and 70 is 66.5.
d. There are 5 months with temperature less than 70, so the chance is 5/12
Answer:
Solving the equation for all real solutions in simplest form.
we get 
Step-by-step explanation:
We need to solve the equation for all real solutions in simplest form.

First simplifying the equation:

Now, we can solve the equation using quadratic formula:

we have a = 1, b=-12 and c=12
Putting values in formula and finding values of x

So, we get value of z: z=10.9 or z=1.1
Solving the equation for all real solutions in simplest form.
we get
