Answer:
j(t)=600*1.09ᵗ⁻¹
Step-by-step explanation:
In 2014, there were 600 jobs.
The next year, the number is expected to grow by 9%.
Since the growth rate is a percentage, this is an example of a geometric sequence.
The nth term of a Geometric Progression is given as:
Uₙ=arⁿ⁻¹
In the first year, population =600
r=(100+9)%=1.09
Therefore the function j(t) that gives the expected number of jobs from the year 2014 is given as:
Uₙ=arⁿ⁻¹
j(t)=600*1.09ᵗ⁻¹ where t=1,2,3...
The value of t=1 is for the year 2014.
Answer:
Option C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.
Step-by-step explanation:
We are given the following in the question:
Variable: Final exam scores (from 0 to 100) for graduating high school seniors.
The following variable is a quantitative variable.
Quantitative variable:
- Their values are expressed in numerical.
- They are either measured or counted.
- Descriptive terms are not used to describe them.
- They can either be continuous or discrete.
Since final scores have numerical values and are counted, they are quantitative variables.
Option C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.
Level of measurement:
A score of zero means no true existence for score. That is true zero exist.
Thus, it is ratio because difference between the values in data can be compared meaningful and they have a true zero.
Answer:1. The coordinates of Jo’s house are (-4,-2).
Step-by-step explanation:
1. Since Jo’s house is reflected across both axes, we must reflect the coordinates two times. So we can reflect the coordinates of Kianna’s house across the x-axis first, which would give you the coordinates (4,-2). Then we reflect (4,-2) across the y axis, giving us the coordinates (-4,-2). So Jo’s house has the coordinates (-4,-2).
Hope this helps.
