B. 23 : 100
C. 46 : 100
D. 3 : 50

Answers

Answer:

Option A is right

Step-by-step explanation:

The graph represents the results of a survey where 400 people were asked to identify the preferred TV channcel.

Of those the data collected gave

WKOD 13%

WANR 22%

WCLM 24%

WWCN 41%

Ratio of people who preferred WANR to those who preferred WCLM

= 22%/24%

=11:12

Hence answer is 11:12
WANR - 22%
WCLM - 24%

Ratio WANR/WCLM=0.22/0.24=11:12

Answer A. is correct.

Q(t)=Qoe^-kt May be used to model radioactive decay. Q representing the quantity remaining after t years, k is the decay constant 0.00011. what is the half-life in years?

Answers

Answer:

Step-by-step explanation:

Given that a substance decays exponentially at the rate of k times the population present.

k = 0.00011

Q0 is the initial population, and Q(t) is the population at time t.

Relationship is given by

Q(t) = Q_(0) e^(-kt) =Q_(0) e^(-0.00011t)

Let after t years there is half life

Then 1/2 =e^(-0.00011t)

Take log

t = -ln2 /(-0.00011) = 6301.34 years

What does a residual value of 1.3 mean when referring to the line of best fit of a data set?A data point is 1.3 units above the line of best fit.
A data point is 1.3 units below the line of best fit.
The line of best fit has a slope of –1.3
The line of best fit has a slope of 1.3.

Answers

The residual value of 1.3mean when referring to the lineofbestfit of a data set is that a data point is 1.3 units above the line of a data set. This is because the given residual value is positive. So, the data point is above the best fit line.

Residual value:

  • A residual value is the standard square error which is calculated from the line of best fit.
  • If the residual value 'r' is positive it means the data point is r units above the best fit line.
  • If the residual value 'r' is negative it means the data point is r units below the best fit line.

Line of best fit:

A line of best fit refers to a line through a  plot of datapoints that best expresses the relationship between those points.

For the given residualvalue of 1.3 mean, a data point is 1.3unitsabove the line of best fit when referring to the line of best fit of a data set. This is because the residual value is positive.

So, Option A is correct.
