Which inequality is equivalent to |x-4/<9?
- 9> X-4 < 9
0.9< X - 4 < 9
OX-4<-9 or X-4 < 9
X – 4 >-9 or x 4 < 9
Answer: x-4>-9 or x-4<9
Step-by-step explanation:
The correct option for the given inequality is x-4>-9 or x-4<9
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given an inequality, |x-4| < 9
Using the rule, if |x| < a then, -a < x < a.
Therefore,
|x-4| < 9
-9 < x-4 < 9
x-4 > -9 or x-4 < 9
Hence, The correct option for the given inequality is x-4>-9 or x-4<9

In order to drive from your home to the store, there has to be at least one operating route. Once a bridge is closed on a route, that route is no longer operating. The probability that bridge 1 is open is 0.8, bridge 2 is 0.93, bridge 3 is 0.9, bridge 4 is 0.92, and bridge 5 is 0.94. What is the probability you can drive to the store? Answer to 3 decimals.
Answer:
The probability of driving to the store is 0.969
Step-by-step explanation:
The remaining part of the question is attached
Solution
There are only two possible ways –
a) Route comprising of bridges 123
b) Route comprising of bridge 45
Probability of success while traveling through Route 123 = P(Bridge 1 open) x P(Bridge 2 open) x P(Bridge 3 open)
= 0.9 x 0.92 x 0.91
= 0.75348
P(Route 123 is closed) = 1 - 0.75348 = 0.24652
Probability of success while traveling through Route 45 =
P(Bridge 4 open) x P(Bridge 5 open)
= 0.94 x 0.93
= 0.8742
P(Route 45 is closed) = 1 - 0.8742 = 0.1258
To travel to store, atleast one route from 123 and 45 should be open.
Probability that you can drive to store :
= P(atleast one route from 123 and 45 is open)
= 1 - P(Both routes 123 and 45 are closed)
= 1 - P(123 is closed)*P(45 is closed)
= 1 - 0.24652*0.1258
= 1 - 0.031012216
= 0.968987784
~ 0.969

Why should you write everything down instead of doing the math in your head?
Answer and Step-by-step explanation:
It ensures that you don't accidently skip a step or get confused by which numbers are being used. By writing it down, it allows you to look back and see if you answer was correct or incorrect.
For example:
On a test, you need to do a complicated math problem that you know you can do in your head. It would still be a good idea to write down the process, so that you can see in front of you the numbers you get and results. If it is incorrect when checking over you answers, then you can go through the steps you made to see where you made a mistake.

write the slope-intercept form of the equation of each line.
Answer:
[tex]y=2x+3[/tex]
Step-by-step explanation:
1. Approach
Slope intercept form is a way of expressing an equation of a line using the slope of a line, and its y-intercept. The general format for the equation of a line in slope-intercept form is the following,
[tex]y=mx+b[/tex]
Find each of the missing pieces of information and substitute it into the equation to find the equation of the line.
2. Find the slope
The slope of a line is the change in the line is can be found using the following formula,
[tex]\frac{y_2-y_2}{x_2-x_1}[/tex]
As one can see on the given graph, two points on the line are the following,
[tex](-2, -1), (-1, 1)[/tex]
Substitute the points into the formula and solve for the slope,
[tex]\frac{(1)-(-1)}{(-1)-(-2)}[/tex]
[tex]=\frac{2}{1}\\\\=2[/tex]
3. Find the y-intercept
The y-intercept of a line is where the line intersects the y-axis. As one can see this point is the following,
[tex](0,3)[/tex]
Thus the y-intercept is (3).
4. Put the information together
Putting all of this information together, substitute the found information into the general equation for slope-intercept form. One can see that the equation of a line is the following,
[tex]y=2x+3[/tex]

Suppose the heights of the members of a population follow a normal distribution. If the mean height of the population is 68 inches and the standard deviation is 4 inches, 68% of the population will have a height within which of the following ranges?
Answer:
68% of the population will have a height between 64 and 72 inches
Step-by-step explanation:
According to the Empirical Rule, 68% of the population will have a height within the range of 1 standard deviation of the mean. This means that the range of possible heights for 68% of the population is between 68-4(1)=64 inches and 68+4(1)=72 inches
In a children's story, a young girl finds that one bowl of soup is too hot, another is too cold, and a third bowl is just
right. Further study reveals that the temperature of the soup bowl that the young girl declared to be just right was
100°F. A researcher would like to test the hypotheses How=100 versus Hou* 100 where ji = the true mean
temperature of all bowls of soup. A 95% confidence interval based on a random sample of 30 bowls of soup is
(100.9, 102.3). Using this interval, can the researcher reject the null hypothesis?
Yes, the null hypothesis can be rejected at the significance level a = 0.05, because 100 is not contained in the and
95% confidence interval.
Yes, the null hypothesis can be rejected at the significance level a = 0.01, because 100 is not contained in the
95% confidence interval.
No, the null hypothesis cannot be rejected at the significance level a = 0.05, because 100 is not contained in the
95% confidence interval.
No, the null hypothesis cannot be rejected at the significance level a = 0.01, because 100 is not contained in the
95% confidence interval
Answer:
A, Yes, the null hypothesis can be rejected at the significance level α = 0.05, because 100 is not contained in the 95% confidence interval.
Step-by-step explanation:
A horticulturist working for a large plant nursery is conducting experiments on the growth rate of a new shrub. Based on previous research, the horticulturist feels the average weekly growth rate of the new shrub is 3cm per week. A random sample of 45 shrubs has an average growth of 1.50cm per week with a standard deviation of 3cm. Is there overwhelming evidence to support the claim that the growth rate of the new shrub is less than 3cm per week at a 0.050 significance level?
Find the value of the test statistic. Round your answer to three decimal places, if necessary.
Answer:
Test statistic = - 3.354
We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.
Step-by-step explanation:
H0 : μ = 3
H1 : μ < 3
The test statistic = (xbar - μ) / (s/ √n)
Xbar = 1.50
μ = 3
s = 3
n = 45
Test statistic = (1.5 - 3) / (3/ √45)
Test statistic = - 1.5 / 0.4472135
Test statistic = - 3.354
Pvalue, using the Pvalue from Z score calculator :
Pvalue = 0.00039826
α = 0.05
Pvalue < α ; We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.

how do you divide a square in half by connecting two vertices?
Answer:
diagonally.
Step-by-step explanation:
the vertices are the corners or angles. square has four angles. if you have to divide it in half by connecting 2 vertices, then you would just need to draw a line from one corner, diagonally to another corner. you have 2 halves that are equilateral triangles. think about a grilled cheese sandwich cut in half. make sense?

Answer:
mean = 10.2 minutes
median = 9.5 minutes
Step-by-step explanation:
To find the mean, add up all of the results and then divide by the number of students in the sample. Therefore, the work should look like this: 15+8+7+7+11+13=61 --> 61/6=10.1666667
To find the median, order the results from least to greatest and then notice which number is the middle value. Since there is an even number of students in the sample, you will find that both 8 and 11 are the middle values when you put them all in numerical order (7, 7, 8, 11, 13, 15). Therefore, you must find the average of those two number in order to get the median. (8+11=19 --> 19/2=9.5)
