Answer:
p=£154,500
T=2years
R=4%
Compound Amount (CA) =?
Now,
CA=p(100+R/100)^T
=154500*(100+4/100)^2
=154500*(104/100)^2
=154500*(1.04)^2
=154500*1.0861
=167107.2
Therefore The value of the investment will be £167107.2 after 2year
The value of the investment at the end of 2 years is £167107.2.
Given that, principal =£154500, time period= 2 years and rate of interest =4%.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]Amount=P(1+\frac{R}{100} )^{nt}[/tex]
Here, Amount = 154500(1+4/100)²
= 154500(1+0.04)²
= 154500(1.04)²
= 154500×1.0816
= £167107.2
Hence, the value of the investment at the end of 2 years is £167107.2.

2y-1/-3 =-5 prove y=8
What are the statements and reasons for this questions?
Answer:
I will provide the steps below.
Step-by-step explanation:
First, You will need to plug in the 8.
2(8)-(1/-3)=-5
Multiply
16-(-1/3)=-5
If we have two negitive it turns into possitive.
16+1/3=-5
16+1/3=-5
This statement is not true becuase if y=8 the equation will be (16+1/3)=5

Solve for x and find de mesures of Angule B
Answer:
x=9.4
b=77.2
Step-by-step explanation:
a+b=180
as they are interior angles
(6x-48)+(4x+38)=180
6x-48+4x+38=180
6x+4x+38-48=180
10x+86=180
10x=180-86
10x=94
x=94/10
x=9.4
b=(4x+38)
b=4x+38
b=4(9.8)+38
b=39.2+38
b=77.2
A researcher wants to test whether a certain sound will make rats do worse on learning tasks. It is known that an ordinary rat can learn to run a particular maze correctly in 18 trials, with a standard deviation of 6. (The number of trials to learn this maze is normally distributed.) The researcher now tries an ordinary rat in the maze, but with the sound. The rat takes 38 trials to learn the maze. (a) Using the .05 level, what should the researcher conclude? Solve this problem explicitly using all five steps of hypothesis testing, and illustrate your answer with a sketch showing the comparison distribution and the rejection region.. (b) Then explain your answer to someone who has never had a course in statistics (but who is familiar with mean, standard deviation, and Z scores).
Answer:
So we reject the null hypothesis and accept the alternate hypothesis that rats learn slower with sound.
Step-by-step explanation:
In this data we have
Mean= u = 18
X= 38
Standard deviation = s= 6
1) We formulate the null and alternate hypothesis as
H0: u = 18 against Ha : u > 18 One tailed test .
2) The significance level alpha = ∝= 0.05 and Z alpha has a value ± 1.645 for one tailed test.
3)The test statistics used is
Z= X- u / s
z= 38-18/6= 3.333
4) The calculated value of z = 3.33 is greater than the z∝ = 1.645
5) So we reject the null hypothesis and accept the alternate hypothesis that rats learn slower with sound.
First we set the criteria for determining the true of value of the variable. That whether the rats learn in less or more than 18 trials.
Then we find the value of z for the given significance value given and the test about to be checked.
Then the test statistic is determined and calculated.
Then both value of z and z alpha re compared. If the test statistics falls in the rejection region reject the null hypothesis and conclude alternate hypothesis is true.
The figure shows that the calulated z value lies outside the given z values

What two number multiply to -48 and add to -2?
Answer:
6 and -8
Step-by-step explanation:
Solve:
xy = 48
x + y = -2
You can say y = -2-x = -(x+2) and then substitute that in the first:
-x(x+2) = 48
-x² -2x - 48 = 0
x² + 2x + 48 = 0
