Answer:
y = - 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (2, - 3)
m = =
= - 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 ← equation of line
Answer:
The interpretation is
There is not sufficient evidence to support the claim that
Step-by-step explanation:
From the question we are told that
The population mean is
Generally
The null hypothesis is
Given from the question that the null hypothesis was rejected then the conclusion will be
There is not sufficient evidence to support the claim that
Answer:
She will find 1054 viruses.
Step-by-step explanation:
The number of viruses after t hours is given by the following equation:
In which N(0) is the initial number of viruses and r is the growth rate, as a decimal.
100 viruses that grow at a rate of 17% per hour.
This means that
So
She will check on the viruses in 15 hours. How many viruses will she find?
This is N(15).
Rounding to the nearest whole number:
She will find 1054 viruses.
