Answer:
- 1/3
Step-by-step explanation:
3x-4 = -5
3x = -5 + 4
3x = -1
x = -1/3
Answer:
B. 50
Step-by-step explanation:
AD=AB so 13=AD also.
DE=12 so EB=12 also.
When you add DE and EB together you get DB= 24
There are 2 legs and 1 hypotenuse to a triangle. Your legs are a+b and you hypotenuse is c.
AD=a(13) AB=b(13) DB=c(24)
P= a+b+c
so you add 13 + 13+ 24
The answer is D) 1,030 45/104
You just have to take the amount of gallons it takes to fill up the pool and divide that by 104
Answer:
Sample mean for solution 1: 19.27; sample mean for solution 2: 10.32
Step-by-step explanation:
To find the sample mean, find the sum of the data values and divide by the sample size.
For solution 1, the sum is given by:
9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7
The sample size is 10; this gives us
192.7/10 = 19.27
For solution 2, the sum is given by:
10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2
The sample size is 10, this gives us
103.2/10 = 10.32
2/3 because 2/3 is pretty much 66%
