Answer:
5<x<6
Step-by-step explanation:
The distribution of speeds along a certain stretch of highway has an mean of 76 mph
and a standard deviation of 7 mph.
What percentage of cars would be traveling slower than 55 mph?
Answer:
0.13%
Step-by-step explanation:
Given that :
Mean = 76mph
Standard deviation = 7 mph
Percentage of cars traveling slower than 55mph
Obtain the Zscore :
X = 55mph
Zscore = (X - mean) / standard deviation
Zscore = (55 - 76) / 7
Zscore = - 3
P(Z < - 3)
From the z table :
P(Z < - 3) = 0.0013
Hence, percentage of cars traveling slower than 55mph is (0.0013 * 100%) = 0.13%

so easy just very confused
Answer:
x=16/3
Step-by-step explanation:
To get the answer you must isolate the x, so first you must add 5 to both sides.
Next you divide by 3 to both sides in order to separate the x from the rest of the equation.
You then get the answer x=16/3
Answer:
x=5.333... or x=16/3
Step-by-step explanation:
3x-5=11
Add 5 to both sides:
3x = 16
Divide both sides by 3:
x=5.333...
The "..." means that the decimal is repeating. So x=5.333... with the number three repeating.
You could also do it this way:
3x-5=11
Add 5 to both sides:
3x = 16
Divide both sides by 3:
3x/3 = 16/3
x=16/3

5(x4) 3-6)
16x-2) 166+2)
x + 26-5) = 3x - 2) - 4
Answer:
2(x - 5) = 2(x - 5) have infinitely
5(x + 4) = 5(x-6) has no salution
5(x + 4) = 3(x-6) has one salution
4(x - 2) = 4(x + 2) has no salution
x + 2(x - 5) = 3(x - 2) - 4 has infinitely
Answer: One solution- 5(x+4)=3(x-6)
Infinitely many solutions- 2(x-5)=2(x-5)
Infinitely many solutions- X+2(x-5)=3(x-2)-4
No solution- 5(x+4)=5(x-6)
No solution- 4(x-2)=4(x+2)
