A newspaper ran a story concerning the increasing prices of mobile phones. The story stated that mobile phone prices dropped a few years ago, but now are beginning to increase in price because of added features.
• According to the story, the average price of all mobile phones a few years ago was £215.
• A large random sample of mobile phones (n = 200) was taken, and their prices recorded.
• We wish to use a hypothesis test to determine if the average price of all mobile phones is now greater than £215.
Required: Define the hypotheses, and with reference to the applicable random variable distribution, find the rejection region appropriate for this test if we are using the significance level α = 0.05.
Answers
Answer:
H0 : μ = 215
H1 : μ > 215
Rejection region :
Zstatistic > Z0.05
Step-by-step explanation:
Given that:
Average price of all mobile phones was £215
Sample size = 200
Significance level (α) = 0.05
To determine if the average price of all mobile phones is now greater than £215
The Null hypothesis (H0) :
H0 : μ = 215
Alternative hypothesis (H1) :
H1 : μ > 215
The rejection region :
|Zstatistic > Zα|
α = 0.05 ; Z0.05
Rejection region :
Zstatistic > Z0.05

Answers
Answer:
A. 13
Step-by-step explanation:
[tex] (6y - 14) + 90 + (2y) = 180 [/tex] (angles on a straight line)
Solve for y
[tex] 6y - 14 + 90 + 2y = 180 [/tex]
Collect like terms
[tex] 6y + 2y - 14 + 90 = 180 [/tex]
[tex] 8y + 76 = 180 [/tex]
Subtract 76 to both sides
[tex] 8y + 76 - 76 = 180 - 76 [/tex]
[tex] 8y = 104 [/tex]
Divide both sides by 8
[tex] \frac{8y}{8} = \frac{104}{8} [/tex]

Every year on November 1, the Stablo family plants a tree. This tradition has
happened for generations and the first tree the family planted is now 183 years
old. Two of the trees were planted in their backyard; one is an apple tree and the
other is a maple tree. The maple tree is older than 100, but was not the first tree
planted. On November 1 of this year, the age of the maple tree is fifteen times
the age of the apple tree.
On November 1 of some year from now, the age of the maple tree will be eleven
times the age of the apple tree. How old are the trees that year?

Beth is making a rope ladder each step of the ladder is 2 1/3 feet wide width as a rope that is 21 feet long how many steps can she make from the rope
Answers
Answer:
Answer: She can make 9 steps from the rope.
Step-by-step explanation:
Given : The width of each step of the ladder = 2\dfrac{1}{3}\text{ feet}2

feet = \dfrac{2(3)+1}{3}=\dfrac{7}{3}\text{ feet}

feet
The length of the rope = 21 feet
Then , the number of required steps = ( length of the rope ) ÷ (width of each step of the ladder)
=21\div\dfrac{7}{3}=21÷

=21\times\dfrac{3}{7}=3\times3=9=21×

Actual question is:
logf 4(3d) + log4 1 = log4 3dSolution:
logf 4 + logf (3d) + 0 = log4 (3d)logf 4 + logf (3d) = log4 (3d)If we assume f = 4, then
log4 4 + log4 (3d) = log4 (3d)log4 4 = 0but log4 4 = 1

1. Approximately what was the total expenditure on entertainment if separated amount of $11,406.30, $1,669.72, $2,506.81 and $1,930.20 were spent?
Answers
Answer:
The approximate expenditure spent on entertainment is $17,513
Step-by-step explanation:
To get the total entertainment expenditure, we simply add up all these values
We have;
11,406.30 + 1669.72 + 2506.81 + 1930.20 = 17,513.03
The total expenditure spent on entertainment is approximately $17,513
Find the 89th term of the arithmetic sequence
-13, -8, -3
Answers
Answer:
427
Step-by-step explanation:
first you have to find the difference between -13 and -8 so we do -13 minus -8 which gives us -13 +8 which is -5. so -13+5=-8 then we try plugging in 5 to the next two numbers -8+5=-3 so the pattern is +5 so now we can do 5*88=440 so now we do -13+440=427

Hermina cut a ft by ft piece of plywood down the diagonal.
A rectangle is 4 feet wide and 8 feet long. A diagonal cut is shown with a line labeled c. The cut divides the rectangle in half and creates two right triangles. The hypotenuse of each right triangle is the line labeled c.
What is the length c of the cut, in feet?
Answers
Answer:
[tex]\sqrt{80} = c[/tex] is the answer.
Step-by-step explanation:
We can solve this using the Pythagorean theorem.
We know we can use the pythagorean theorem because it has a 90 degree angle.
[tex]a^{2}+ b^{2}= c^{2}[/tex]
We are given the sides 4 and 8.
[tex]4^{2} + 8^{2} = c^{2}[/tex]
[tex]80 = c^{2} \\\\\sqrt{80} = c[/tex]

Why did we used the equation "(8x - 8) + 100° = 180°" to find x?
Because, sum of interior angle in the same side of two parallel lines are always equal to 180°.

The random variable X is known to be uniformly distributed between 2 and 12. Compute E(X), the expected value of the distribution.
Answers
Answer:
The expected value of the distribution is 7.
Step-by-step explanation:
The random variable X is known to be uniformly distributed between 2 and 12.
The probability density function of X is:
[tex]f_{X}(x)=\frac{1}{b-a};\ a<X<b[/tex]
Here a = 2 and b and 12.
Compute the expected value of the distribution as follows:
[tex]E(X)=\frac{a+b}{2}[/tex]
[tex]=\frac{2+12}{2}\\\\=\frac{14}{2}\\\\=7[/tex]
Thus, the expected value of the distribution is 7.
