Considering an arithmetic sequence, it is found that:
8. Two consecutive terms in the sequence of eruption times are: 94, 106.
9. The common difference of the sequence of eruption times is of 12.
10. The general rule of the sequence of eruption times is: [tex]a_n = 46 + 12(n - 1)[/tex]
What is an arithmetic sequence?An arithmetic sequence has the difference between consecutive terms assuming always the same value, being called common difference d.
The nth term of an arithmetic sequence is given by the following general rule:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
In the context of this problem, the sequence is given as follows:
46, 58, 70, 82, ...
Hence the common difference is given by:
d = 82 - 70 = 70 - 58 = 58 - 46 = 12.
The next two terms of the sequence are:
82 + 12 = 94.94 + 12 = 106.Considering that the first term is of 46, the general rule for the sequence is given by:
[tex]a_n = 46 + 12(n - 1)[/tex]
What is the missing information?The sequence of eruption times is given by:
46, 58, 70, 82, ...

A model car is constructed with a scale of 1:15. If the actual car is 12 feet long, which proportion represents the length x of the model car?
The length of the model car based on the information is 0.8 feet.
What is scale?It should be noted that scale simply shows the relationship between a measurement on a model as well as the corresponding measurement on the actual object.
From the information, the model car is constructed with a scale of 1:15.
When the actual car is 12 feet long, the length of the model will be illustrated as x. This will be:
= 1/15 = x / 12
Cross multiply
15x = 1 × 12
15x = 12
Divide
x = 12 / 15
x = 0.8
The length is 0.8 feet.

a single cell amoeba doubles every 6 days. about how long will it take one amoeba to produce a popultion of 1000?
39.8631371388 days will be taken by amoeba to produce a population of 1000 .
What is log functions ?The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be increased in order to obtain a number x is the logarithm of x to the base b.
CalculationsSo the number of amoebae doubles every cycle (a cycle being four days). So we just multiply it by 2 every cycle
2 x 2 x 2...
A simple way to write this is using an exponent with a base of 2
2n
where n represents the number of cycles.
2^1 = 2 amoebae after one cycle
2^2 = 4 amoebae after two cycles
2^3 = 8 amoebae after three cycles, and so on
So you can substitute different numbers for n until you find the correct number of cycles, or you can take the base 2 logarithm of the equation.
2n = 1000
log2(2n) = log2(1000)
n = log2(1000)
Remember, n represents the number of cycles, so once you find it you will have to multiply it by the length of each cycle.
log₂(1000) = 9.9657842847 cycles this is the time taken by the amoeba to produce a population of 1000
therefore days taken will be = 9.9657842847 * 4 = 39.8631371388 days

Write a function that gives the total cost R(t)R(t)R, left parenthesis, t, right parenthesis, in dollars, of Ebuka's rent if he pays it ttt weeks late.
The function that represents the total cost of Ebuka's rent R(t) if he pays it t weeks late is R(t) = 750 + t/25.
Given that:-
Monthly rent of Ebuka = $ 750
Interest rate charged for late submission of rent by landlord = 4 %
We have to write a function that represents the total cost of Ebuka's rent R(t) if he pays it t weeks late.
We know that,
Total rent paid by Ebuka if he is t weeks late = Monthly fixed rent +( Interest rate per week)*(Number of weeks he is late)
R(t) = $ 750 + (4/100)*t

Write the equation of the line that passes through
the points (-1, 2) and (6, 3) in slope-intercept form.
The equation in slope intercept form is [tex]\frac{x}{7} +\frac{15}{7}[/tex].
Given that the line passes through two points (-1,2) and (6,3)
Slope of the line passing through (x1,y1) and (x2,y2) is
[tex]\frac{y2-y1_ }{x_{2-x_{1} } }[/tex]
Hence slope of our line =
(3-2)/(6+1) = 1/7
So in slope intercept form the equation would be
y = 1/7 x +C
to find C
Since (-1,2) lies on the line substitute these in the line equation
2 = 1/7(-1)+c
C = 2+1/7 = 15/7
Hence equation in slope intercept form is [tex]\frac{x}{7} +\frac{15}{7}[/tex].
What is slope intercept form?The slope-intercept form of a line is one of the most common forms used to represent the equation of a line. The slope-intercept formula can be used to find the equation of a line given the slope of the line and the y-intercept (the y-coordinate of the point where the line intersects the y-axis).

the significance level is 5%. the p-value was 0.014. what is the probability of a type i error for this hypothesis test (assuming that the null hypothesis is true)?
Feedback: With p-value <e; α our decision is to reject the null hypothesis.
What is null hypothesis?The null hypothesis assumes that any kind of difference between selected features appearing in the dataset is due to chance. For example, if the expected return from gambling is really zero, the difference between the average return in the data and zero is just a coincidence. The null hypothesis indicates that there is no relationship between the two population parameters.If the hypothesis indicates a relationship between the two parameters, the results may be due to experimental or sampling error. A scientific hypothesis is a statement of what researchers expect when conducting research. However, a statistical hypothesis is a statement of what a statistician does not expect.

Yes, it is proportional because it is a line that intersects with the origin.
No, it is not proportional because the x-axis and y-axis are not labeled correctly.
No, it is not proportional because the line does not intersect with the origin.
The statement which shows whether this graph shows a proportional relationship is: B. Yes, it is proportional because it is a line that intersects with the origin.
What is a graph?A graph can be defined as a type of chart that's commonly used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
In Mathematics, the graph of any proportional relationship is typically characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-coordinate decreases or increases, the values on the y-coordinate decreases or increases simultaneously.
In this context, we can reasonably infer and logically deduce that this graph shows a proportional relationship.
