Answer:
a) The calculated value t = 5.903 > 2.572 at 0.01 level of significance
Null hypothesis is rejected at 0.01 level of significance
There is a true mean value is less than 10
b) p - value 0.00001
The p - value 0.00001 < 0.01
The result is significant at p<0.01
Step-by-step explanation:
Step(i):-
Given mean of the population = 10
Sample size 'n'= 35
Mean of the sample x⁻ = 14.44
Standard deviation of the sample 's' = 4.45
Level of significance ∝ = 0.01
Step(ii):-
Null Hypothesis H₀ : μ >10
Alternative Hypothesis : H₁ : μ < 10
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{14.44-10}{\frac{4.45}{\sqrt{35} } }[/tex]
t = 5.903
Degrees of freedom = n-1 = 35-1 = 34
tabulated value t₀.₀₁,₃₄ = 2.572
The calculated value t = 5.903 > 2.572 at 0.01 level of significance
Null hypothesis is rejected at 0.01 level of significance
There is a true mean value is less than 10
p- value :
p - value 0.00001
The p - value 0.00001 < 0.01
The result is significant at p<0.01

What is the perimeter of a rectangle if the length is (3x + 2) and the width is (2x - 5)
Answer: 10x-6
Step-by-step explanation:
we know that perimeter P is 2L+2W
2L= 2(3x+2)=6x+4
2W=2(2x-5)=4x-10
P=6x+4+4x-10=10x-6

Solve for 'p'. Show all work: 2(-4x + 8) ≤ 20
Answer: Answer: x≥ −1 /2
Step-by-step explanation:
Answer:
x ≥ -1/2 or x ∈ [-1/2, +∞)
Step-by-step explanation:
2(-4x + 8) ≤ 20
divide both sides by 2
-4x + 8 ≤ 10
move 8 to the right
-4x ≤ 10-8
-4x ≤ 2
divide both sides by -4. Flip the sign since a negative value is being divided
x ≥ - 1/2

What is the answer to this question?
Answer: Choice A) 4, 3, 5, 1, 2
=====================================================
Explanation:
Since tan(x) = sin(x)/cos(x) is a known and widely used trig identity, this must mean step 4 goes first.
The answer is between choice A and choice B.
The question is now: What is the correct second step?
It's either step 3 (choice A) or step 5 (choice B)
It turns out that step 3 is the correct statement after step 4. The sin(2x) breaks up into 2sin(x)cos(x), while the cos(2x) breaks up into cos^2(x)-sin^2(x). There are three different variations for the cos(2x) and this just happens to be one of them.
So we can rule out choice B and go with choice A as the final answer.

If you invest 11775.00 at a rate of 7.10 percent annum, compounded quarterly what will the total value of your investment be after 4 years
Answer:
The total value of the investment will be $15,603.38 after 4 years
Step-by-step explanation:
Compound Interest
It occurs when interest in the next period is earned on the principal sum plus previously accumulated interest.
We'll use the formula:
[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
The investment is P=$11,775 at a rate of r=7.10% = 0.071 compounded quarterly. Since there are 4 quarters in a year, n=4. The investment will last t=4 years, thus:
[tex]{\displaystyle A=\$11,775\left(1+{\frac {0.071}{4}}\right)^{4*4}}[/tex]
[tex]{\displaystyle A=\$11,775\left(1.01775\right)^{16}}[/tex]
[tex]\boxed{A = \$15,603.38}[/tex]
The total value of the investment will be $15,603.38 after 4 years
x=y+3
4 = 3x - 2y
It’s substitution but I don’t know how to do it
Answer:
4= 3(y+3) - 2y (substitute the given x-value into the equation to solve for y)
4= 3y+9-2y (use the distributive property)
4=y+9 (combine like terms)
y= -5 (subtract 9 from both sides to isolate the y-term)
plug it in
x= (-5)+3
x=-2
(-2,-5)
