£2,300 is invested for 4 years at 5% per year simple interest work out the total interest
Answer:
£460
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2300 × 0.05 × 4 = 460
I = £ 460.00
The simple interest accumulated
on a principal of £ 2,300.00
at a rate of 5% per year
for 4 years is £ 460.00.

solution of 4x=400 lies between two consective integers
Answer:
100
Step-by-step explanation:
Given the equation 4x = 400, we are to find the value o x
4x = 400
Divide both sides by 4
4x/4 = 400/4
x = 100
Hence the value of x is 100
A group of researchers was interested in the effect of music on the behavior of dogs. Specifcally, they wanted to
measure the effect of classical music on sleepiness as an indication of dogs' mental relaxation. They conducted
the following study on a group of 400 Jack Russell Terriers.
Every day for 4 months, the researchers would play Beethoven's Moonlight Sonata for 1 hour occurring
randomly between 9 a.m. and 12 p.m. During the entire 3 hours observers would record the times in which
each dog was sleeping. By the end of the 4 months, the researchers calculated and compared the percentage of
time each dog spent sleeping during each of two conditions: while the music was playing and while it wasn't
Is the study appropriate for the statistical questions it's supposed to answer?
Answer:
Step-by-step explanation:
The first part of the question would be: B) Experiment
The second part would be: C) No, because the sample the study used isn't representative of all dogs.
The independent variable is a variable that represents a quantity being manipulated in an experiment, the control group will be the group that did not hear the music, and the experimental group the group that heard the song.
What is Independent variable?An independent variable is a variable that represents a quantity being manipulated in an experiment.
xxx is often the variable used to represent the independent variable in an equation.
Dependent variables
A dependent variable represents a quantity whose value depends on how the independent variable is manipulated.
yyy is often the variable used to represent the dependent variable in an equation.
Confounding variable
It is a variable that influences both the dependent variable and the independent variable, causing a spurious association. The confounding variable is a causal concept and as such cannot be described in terms of correlations or associations.
With this information, we can conclude that, The control group are people who have not heard the music, the experimental group are those who heard the music, and the hypothesis is that music can change people's heart rate.

Graph the solution set to this inequality.
-2x+9≤5x-12
Answer:
x>3
Step-by-step explanation
-2x+9≤5x-12
Step 1: Subtract 5x from both sides.
−2x+9−5x≤5x−12−5x
−7x+9≤−12
Step 2: Subtract 9 from both sides.
−7x+9−9≤−12−9
−7x≤−21
Step 3: Divide both sides by -7.
−7x−7≤−21−7
Answer:
x≥3
The solution set to this inequality -2x+9≤5x-12 is x ≥ 3 .
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
According to the question
Solution set of inequality -2x+9≤5x-12.
-2x+9 ≤ 5x-12
-2x-5x ≤ -9-12
-7x ≤ -21
x ≥ 3 (sign changes as -ve sign eliminates )
