A dental hygienist is a health-care professional who works alongside a dentist to meet the oral health care needs of patients. Asked by one of her clients who needs to get a cavity filled what the average number of cavities a person gets filled by the time they are 50 years old, the hygienist responds that she will gather and determine not just the average, but also the median and the mode - because she would like to know this information herself. A bit of research turns up the following data table taken from a research project of a graduate student. The graduate student surveyed 20 people aged 50 from around Idaho.

Assuming the lines are evenly spaced between the integers, what number, in decimal notation, is represented by the plotted point?
Answers
Answer:
-1.4
Step-by-step explanation:
There are five increments between -2 and -1, so we find the difference between -2 and -1, which is 1. Divide 1 by five (increments)=.2
This means that every increment is worth 0.2.
If we see it from the left to right, from -2, there are 3 increments to the right, so multiply three by 0.2 which is 0.6, add 0.6 to -2, which is -1.4.

Answer: 12. x =7 13. x =6
Step-by-step explanation:
Both angles in the triangle has to equal to each other because they are both equivalent.
Set both expressions equal to each other and solve for x.
12. 5x = 35 Divide both sides by 5
x = 7
13. 3x = 5x - 12 Subtract 5x from both sides
-5x -5x
-2x = -12 Divide both sides by -2

problems; e.g. 200 bottles of equal capacity hold 350 litres of water.
How much water does each bottle hold?
Answers
Each bottle holds 1.75 liters of water.
To determine how much water each bottle holds, we can divide the total amount of water by the number of bottles.
Given that 200 bottles hold 350 liters of water, we divide 350 liters by 200 bottles:
350 liters / 200 bottles = 1.75 liters per bottle
Therefore, each bottle holds 1.75 liters of water.Therefore, each bottle holds 1.75 liters of water.
This means that if we were to fill each bottle to its maximum capacity, it would hold 1.75 liters of water.
It's important to note that this assumes each bottle has an equal capacity and that the water is evenly distributed among them.

6y−40=−4(Simplify both sides of the equation)

A new process for producing a type of novolac resin is supposed to have a mean cyclic time of 3.5 hours per batch. Six batches are produced, and their cyclic times, in hours, were 3.45 3.47 3.57 3.52 3.40 3.63 Can you conclude that the mean cyclic time is greater than 3.5 hours
Answers
The requried, we cannot conclude that the mean cyclic time is greater than 3.5 hours for the new process of producing a type of novolac resin based on the given data.
To determine if we can conclude that the mean cyclic time is greater than 3.5 hours for the new process of producing a type of novolac resin, we need to perform a hypothesis test.
We can use a one-sample t-test to test the null hypothesis that the mean cyclic time is equal to 3.5 hours against the alternative hypothesis that the mean cyclic time is greater than 3.5 hours.
Using the given data, we can calculate the sample mean and sample standard deviation of the cyclic times for the six batches produced. The sample mean is:
x = (3.45 + 3.47 + 3.57 + 3.52 + 3.40 + 3.63) / 6
= 3.50 hours
The sample standard deviation is:
[tex]s = \sqrt ((3.45 - 3.50)^2 + (3.47 - 3.50)^2 + (3.57 - 3.50)^2 + (3.52 - 3.50)^2 + (3.40 - 3.50)^2 + (3.63 - 3.50)^2) / (6 - 1)) }[/tex]
= 0.086 hours
The test statistic for the one-sample t-test is:
[tex]t = ( \bar x-\mu) / (s / \sqrt(n))[/tex]
where μ is the hypothesized mean cyclic time, n is the sample size, and s is the sample standard deviation.
Substituting the given values, we get:
[tex]t = (3.50 - 3.5) / (0.086 / \sqrt(6))[/tex]
= 0
The degree of freedom for the t-test is n - 1 = 5.
Using a t-table or a calculator, we can find the critical value of t for a one-tailed test with α = 0.05 and 5 degrees of freedom to be 1.833.
Since the calculated t-value of 0 is less than the critical value of 1.833, we fail to reject the null hypothesis. Therefore, we cannot conclude that the mean cyclic time is greater than 3.5 hours based on the given data.
Therefore, we cannot conclude that the mean cyclic time is greater than 3.5 hours for the new process of producing a type of novolac resin based on the given data.

The number of students in Mr.Romano’s class is 35.
Given that, in Mr. Romano‘s class, 40% of the students like baseball.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of students in Mr.Romano’s class be x.
Here, 40% of x = 14
⇒ 40/100 × x = 14
⇒ 0.4x = 14
⇒ x = 14/0.4
⇒ x = 35
Therefore, the number of students in Mr.Romano’s class is 35.
