Find the critical value tc for the confidence level cequals 0.95 and sample size nequals 19.
The critical values are fixed values which can be obtained from the standard t crit tables. We can find the critical value tc when the degrees of freedom and confidence level are given. The degrees of freedom is simply:
Degrees of Freedom = Number of samples – 1
Degrees of Freedom = 19 – 1
Degrees of Freedom = 18
From the t critical tables, the tc corresponding to Degrees of Freedom equal to 18 and Confidence level equal to 95% is as follows:
tc = 2.101
Therefore this means that any t value beyond 2.101, we already reject the null hypothesis.

A certain triangle has two 45 angles. What type of triangle is it?
A. Acute scalene
B. Right scalene
c. Right isosceles
D. Acute isosceles
Answer:
C. Right isosceles
Step-by-step explanation:
In Acute scalene triangle, all angles are acute ( less than 90 degrees ) and different,
In Right scalene triangle, two angles are acute and different, while, the third angle is of 90°.
In Right isosceles triangle, two angles are acute and equal, while, the third angle is of 90°.
In Acute isosceles, all angles are acute in which any two angles are equal.
Now, given,
The two angle of the triangles are 45° and 45°,
Let x be the third angle,
⇒ x + 45° + 45° = 180°
⇒ x + 90° = 180°
⇒ x = 90°
Hence, the angles of given triangle are 45°, 45° and 90°,
By the above definitions,
It is clear that, given triangle is right isosceles.
Option C is correct.
What is the circumference of a circular disc with a diameter of 10 centimeters? (Round your answer to the nearest tenth.)
The circumference of the circle is 31.4 cm
What is Circumference of circle?The circumference of a circle refers to the measure of its boundary. If we open a circle and measure the boundary just like we measure a straight line, we get the circumference of the circle in terms of units of length like centimeters, meters, or kilometers.
Now let us learn about the elements that make up circumference. These are the three most important elements of a circle.
Center: The center of the circle is a point that is at a fixed distance from any other point from the circumference.Diameter: The diameter is the distance across the circle through the center, it is a line that meets the circumference at both ends and it needs to pass through the center.Radius: The radius of a circle is the distance from the center of a circle to any point on the circumference of the circle.The formula for the circumference of a circle is expressed using the radius 'r' of the circle and the value of 'pi'. It is expressed as, Circumference of a circle formula = 2πr.
Given:
diameter= 10 cm
So,
Circumference of circle is = πd
=3.14* 10
=31.4 cm

A pet store has 7 tanks of fish. Each tank has k fish. Using k, write an expression for the total number of fish in the store.
The expression which represents the total number of fish in the store is 7k.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given,
Number of tank = 7
Number of fish in each tank = k
The total number of fish = number of tanks x number of fish in each tank
The total number of fish = 7 x k = 7k
Hence "The expression which represents the total number of fish in the store is 7k".

a mail distribution center processes as many as 150,000 pieces of mail each day. the mail is sent via ground and air. each land carrier takes 1800 pieces per load and each air carrier 1500 pieces per load. the loading equipment is able to handle as many as 150 loads per day. let X be the number of loads by air carriers and y the number of loads by air carriers. write a system of inequalities that represents this situation
Final answer:
The system of inequalities representing this situation is:
1500X + 1800Y ≤ 150,000.
X + Y ≤ 150.
X ≥ 0 and Y ≥ 0.
Explanation:
Let's define X as the number of air carrier loads and Y as the number of land carrier loads. Given that the mail distribution center processes up to 150,000 pieces of mail each day and the loading equipment can handle a maximum of 150 loads per day, we can write the following system of inequalities:
The total mail processed by both air and land carriers cannot exceed 150,000 pieces:
1500X + 1800Y ≤ 150,000.
The total number of loads carried by both air and land carriers cannot exceed 150 loads:
X + Y ≤ 150.
Furthermore, since there cannot be a negative number of loads, both X and Y have to be non-negative:
X ≥ 0 and Y ≥ 0.
These inequalities model the constraints for the mail distribution center's operations.

(03.01) Is the following relation a function? y equals the sine of 3 x
Answer:
Yes. This is a function.
Step-by-step explanation:
Given is a function as
[tex]y = sin 3x[/tex]
We find that for every x in the domain of real numbers there is a unique image for every x as sin 3x.
Thus this relation given satisfies the requirements of a function.
Also we find that this function is periodic with amplitude 1 and period = 2pi/3
So vertical line test if done will find that there is only one intersection for every vertical line throughout the domain
Hence this relation is definitely a function

The graph shows the number of paintballs a machine launches, y, in x seconds::
A graph titled Rate of Launch is shown. The x axis label is Time in seconds, and the x axis values are from 0 to 20 in increments of 4 for each grid line. The y axis label is Number of Balls, and the y axis values from 0 to 80 in increments of 16 for each grid line. A line is shown connecting points on ordered pair 4, 16 and 8, 32 and 12, 48 and 16, 64.
Which expression can be used to calculate the rate per second at which the machine launches the balls?
fraction 64 over 4
fraction 4 over 64
fraction 16 over 4
fraction 4 over 16
a fraction should be number of balls over time per second
so it should be 16/4 which is 4 balls per second
Answer: fraction 16 over 4
Step-by-step explanation:
The given graph shows the number of paintballs a machine launches, y, in x seconds.
We know that the rate of change of a line is given by :-
[tex]k=\frac{y_2-y_1}{x_2-x_1}[/tex]
The ordered pairs on the line in graph are (4, 16) and (8, 32) and (12, 48) and (16, 64).
Thus, the rate per second at which the machine launches the balls is given by :-
[tex]k=\frac{32-16}{8-4}=\frac{16}{4}
What is the approximate distance between the points (-5, 1) and (-2, 3) on a coordinate grid ?
graph the line with the slope 1/3 and y-intercept -2
The graph of the line y = (1/3)x - 2 can be plotted on a graph paper by choosing some arbitrary values of x.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
The given line in terms of the slope-intercept method can be written as,
y = (1/3)x - 2.
Now to plot the graph on graph paper or any digital tool we have to choose some arbitrary values of x that corresponds to some values of y.
Like at x = 0 y = -2 So, the coordinates are (0, -2).
