Y=-4x.-3 y= -2x + 1 What is y and x?
2 answers:
Answer:
The value of x=-2 and the value of y=5
Step-by-step explanation:
we have
Y=-4x-3 -----> equation A
y= -2x + 1 -----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The intersection point is (-2,5)
see the attached figure
therefore
The value of x=-2 and the value of y=5

Answer:
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 158.9
Standard Deviation, σ = 90.4
We are given that the distribution is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.39
Calculation the value from standard normal z table, we have,
133.68 separates the bottom 39% means from the top 61% means.
The best type of chart for quickly deriving the mode of a sample data is called the Stem-and-Leaf Plot.
<h3>What is a Stem-and-Leap Plot?</h3>
In statistics, the Stem-and-Leaf Plot is an easy-to-make easy-to-read kind of graph that is derived from the table holding the sample data.
The Box-and-Whisker Plot on the other hand is best for visually depicting the five-number summary of any set of data, which are:
- Minimum
- First Quartile
- Median (Second Quartile)
- Third Quartile; and
- Maximum.
It is to be noted that referenced plots are not indicated hence, the general answer.
