One way is that an inequality can have a dotted or solid line and another way is that you shade one side of the on an inequality.
Answer:
0.8770
Step-by-step explanation:
We are dealing with a mean of a sample, so we use the formula
Our mean, μ, is 174.9 and our standard deviation, σ, is 35.2. Our sample size, n, is 35. To find P(X > 168),
z = (168-174.9)/(35.2÷√35) = -6.9/(35.2÷5.9161) = -6.9/5.9499 = -1.16
Using a z table, we see that the area under the curve to the left of this value is 0.1230. However, we want the area to the right; this means we subtract from 1:
1-0.1230 = 0.8770
Assuming you are supposed to solve for the variable "t",
9 - (t ÷ 6) = 5
Subtract 9 from both sides.
9 - 9 - (t ÷ 6) = 5 - 9
Simplify.
- (t ÷ 6) = -4
Distribute -1 throughout the parenthesis.
-t ÷ -6 = -4
Multiply both sides by -6.
-t ÷ -6 × -6 = -4 × -6
Simplify.
-t = 24
Divide both sides by -1.
-t ÷ -1 = 24 ÷ -1
Simplify.
t = -24
Answer:
well i know 3 is the lowest but i don't know how high it goes.
Range is where the graphs highest and lowest.

15% = 0.15
0.15 x 20 = 3
15% of 20 is 3.
