Answer:
Graph of the inequality x< -3 as shown below in the figure.
Step-by-step explanation:
Given the inequality: x < -3
Graph of this inequality as shown below in the figure.
All the points that are lie in the shaded area satisfy the equation x < -3 or
In other words, we can say that x can take any value less than -3 .
x ≠ -3 or any number that is greater than -3.
Since there is a strict inequality i.e x < -3 , the points that lie on the line x = -3 does not satisfy the equation.
Therefore, the dotted line is marked at x = -3
Answer:
With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to the normal distribution if:
np > 5, n(1-p) > 5
70% of the drivers traveling on a major interstate highway exceed the speed limit.
So p = 0.7.
Would a random sample of 50 cars have been large enough and why?
With n = 50
np = 50*0.7 = 35 > 5
n(1-p) = 50*0.3 = 15 > 5
With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.
Answer:
X=2
Step-by-step explanation:
9x+1=2x+15
1. restar 1 de ambos lados ejemplo: 9x+1-1=2x+15-1
2. simplificar Ejemplo: 9x=2x+14
3. restar 2x de ambos lados ejemplo: 9x-2x=2x-2x+14
4. simplificar ejemplo: 7x=14
5.divide ambos lados entre 7 ejemplo: 7x/7= 14/7
6.Simplificar ejemplo: x=2
