A quality control engineer is testing the battery life of a new smartphone. The company is advertising that the
battery lasts 24 hours on a full-charge, but the engineer suspects that the battery life is actually less than that.
They take a random sample of 50 of these phones to see if their average battery life is significantly less than 24
hours.
Let u represent the mean battery life for this population of phones.
The question requires stating the Null and Alternative hypothesis for the scenario described :
Answer:
H0 : μ = 24
H1 : μ < 24
Step-by-step explanation:
The claim or hypothesis to be tested in a statistical problem or analysis is the alternative hypothesis. This is usually the opposite of the Null hypothesis which is the usually the initial truth until there is significant evidence provided using statistical test to prove otherwise.
The null hypothesis, H0 in the scenario above is :
H0 : μ = 24 ( average battery life is 24 hours)
The alternative hypothesis is the claim, that is. The mean battery life not up to 24 hours ;
H1 : μ < 24

$10,000 at an annual rate of 7%, compounded semi-annually, for 2 years
Use the compound interest table to find each balance
Will give brainliest 5 stars and thanks
Answer:
[tex]\$13,107.96[/tex]
Step-by-step explanation:
Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.
Therefore, we can set up the following equation to find the new balance after 2 years:
[tex]\text{New balanace}=10,000\text{ (old balance)}\cdot 1.07\cdot 1.07\cdot 1.07\cdot 1.07,\\\text{New balanace}=10,000\cdot 1.07^4=\boxed{\$13,107.96}[/tex]

Answer: 102.5
Step-by-step explanation:
Area of triangle: 8*6=48, 48/2=24
Area of semicircle: 2pir^2=2pi(5)^2=157
Because its semi circle it is 157/2 which equals 78.5
Total area:24+78.5=102.5
Answer:
102.5
Step-by-step explanation:
Semi circle = 78.54 ≈ 78.5
Using formula A = πr²
Area triangle = 24
Using formula A = 1/2(bh)
Sum = 78.5 + 24 = 102.5

Which operation would be last when solving the inequality -5x + 9 < -6
Answer: divding both sides by -5
Step-by-step explanation:
Subtract 9 from both sides.
−5x+9−9<−6−9
−5x<−15
Step 2: Divide both sides by -5.
−5x/−5<−15/−5
x>3
Find the median and mean of the data set below:
13,6,47,0
Answer:
Median:9.5
Mean:16.5
Step-by-step explanation:
Median: Put them in order, find the middle, since there is two median we add them together, then divide them by 2 and there's your answer.
Mean: Add the numbers: 0+ 6+ 13+47= 66
Divide by how many numbers (there are 4 numbers): 66/ 4= 8

Identify the volume of the hemisphere in terms of π. HELP ME PLEASE!!! THE RED IS THE ONE I GOT WRONG!
Answer:
6174π
Step-by-step explanation:
The equation for a whole sphere is 4/3 π(r)³
Given the diameter of 42, we can conclude that the radius would be 21
Next, we would plug in these variables and get 4/3 π(21)³
Simplify all of this down and you would get 12348π
Keep in mind that we are working with a hemisphere. That means that we need to take half of 12348π
Divide that by 2 and you get 6174π
Hope this helps! :)
A triangle is formed by A(0,1), B(1,0), and C(2,4). If the triangle is rotated 90 degrees counterclockwise, which algebraic representation would be used? Select one:
0 (2, y) + (-1, - y)
O (, y) + (y, - 2)
0 (2,y) → ( - 1, y)
0 (2,y) → ( - y, z)
Answer:
[tex](x,y) \to (-y,x)[/tex]
Step-by-step explanation:
Given
[tex]A = (0,1)[/tex]
[tex]B = (1,0)[/tex]
[tex]C = (2,4)[/tex]
90 degrees counterclockwise rotation
Required
The algebraic representation
Let the coordinate point be [tex](x,y)[/tex]
The rule of 90 degrees counterclockwise rotation is:
[tex](x,y) \to (-y,x)[/tex]
So, we have:
[tex]A = (0,1)[/tex] [tex]\to (-1,0)[/tex]
[tex]B = (1,0)[/tex] [tex]\to (0,1)[/tex]
[tex]C = (2,4)[/tex] [tex]\to (-4,2)[/tex]
