D. The company's chocolate bars weigh 3.2 ounces on average.
Step-by-step explanation:
We are given that a company claims that its chocolate bars weigh 3.2 ounces on average.
The company took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.
Definition of 95% confidence level: 95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.
Thus by considering definition we can conclude that The company's chocolate bars weigh 3.2 ounces on average.
Thus Option D is correct.
D. The company's chocolate bars weigh 3.2 ounces on average.

Pythagorean theory baby! Okay so the Pythagorean theory is a² + b² = c² so lets draw a triangle and label our sides. So we know 8² + 15² = c² so I'm going to find the square root of all of our numbers. We get 64 + 225 = c² so then add 64 + 225 = 289 then I take the square root of 289 which equals 17 . This answer also makes sense because out hypotenuse should always be bigger then the legs.
I'm pretty sure thats right, Hope this helps.

Write an equation in slope-intercept form of the line that passes through the given points.
Answers
Answer:
y = 1/2x+1
Step-by-step explanation:
Slope = Δy/Δx
The difference is y increases by 1 and difference in x increases by 2. So the slope is 1/2.
Slope-intercept form: y=mx+b
We take point (0,1) and input into this equation.
1= 1/2×0 +b
1 = b

Which of the following would not be a line in solving the equation:
7x-8-5x = 52
12x = 60
12x = 44
12x - 8 = 52
x = 5
Answers
Answer:
Step-by-step explanation:
Let's actually solve the equation. By doing so we should readily see which of the given equatins are not part of the solution.
7x - 8 - 5x = 52 becomes 2x - 8 = 52 if we consolidate the x terms. Next, we consolidate the constant terms on the right, obtaining 2x = 60.
Then x = 30 is the solution.
12x = 60 would not be part of the solution.
12x = 44 would not either.
12x - 8 = 52 would not either.
x = 5 would not be part of the solution.
Again: The solution is x = 30.

Answers
Answer:
Each constellation will have 5 little stars.
Step-by-step explanation:
First, let's organize the information we have:
5 big stars25 little starsEach constellation should have 1 big starEach constellation should have the same amount of starsNow, let's solve the problem:
Each constellation should have 1 big star, and Seth has 5 big stars, so we can infer that there would be 5 constellations.Since each constellation have 1 big star, and the amount of stars in each constellation is the same, the amount of little stars in each constellation are the same.We have 25 little stars, and there are 5 constellations; 25 ÷ 5 = 5, so each constellation have 5 little stars.Find the volume of the cube in inches 3^ below.

Indicate the equation of the given line in standard form.
The line that contains the point Q( 1, -2) and is parallel to the line whose equation is
y - 4 = 2/3 (x - 3)
Answers
Answer:
The equation of the line is;
3y = 2x-8
Step-by-step explanation:
Firstly, we need the to get the slope of the given line
To do this, we will write the equation of the line in the standard form
the standard form
is;
y = mx + b
where m is the slope and b is the y-intercept
y -4 = 2/3(x-3)
y -4 = 2x/3 - 2
y = 2x/3 -2 + 4
y = 2x/3 + 2
with respect to the given equation, the slope of the line is 2/3
Mathematically, when two lines are parallel, the slopes of the line are equal
So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)
so;
y = 2x/3 + b
So substitute the values of (1,-2)
1 for x and -2 for y
-2 = 2/3(1) + b
-2 = 2/3 + b
b = -2 - 2/3
b = (-6-2)/3 = -8/3
So the equation of that line is;
y = 2/3x - 8/3
Multiply through by 3
3y = 2x - 8

A daily newspaper sells monthly subscriptions for $15. Each individual copy of the newspaper costs $0.75. In a month that has exactly 30 days, how much could be saved by purchasing a subscription instead of purchasing an individual copy each day?
Answers
Answer:
With the subscription, $7.5 will be saved.
Step-by-step explanation:
Giving the following information:
A daily newspaper sells monthly subscriptions for $15. Each copy of the newspaper costs $0.75.
First, we need to calculate the total cost of buying 30 newspapers individually:
Total cost= 0.75*30
Total cost= $22.5
Difference= 22.5 - 15= $7.5
With the subscription, $7.5 will be saved.
The equation A= 1750(1.04)t represents an account balance t years after the account was created. Which statement is correct?
A. The account balance will decrease 0.04% each year.
B. The account balance will increase 0.04% each year.
C. The account balance will decrease 4% each year.
D. The account balance will increase 4% each year.
Answers
Answer:
D. The account balance will increase 4% each year.
Step-by-step explanation:
Given the equation :
A= 1750(1.04)t
This is an exponential growth rate equation which has it's general format as :
A = A0 * (1 + r)^t
A0 = initial value,
Since (1 + r) is greater Than 1 ; then we conclude that it is a growth relation.
1 + r = 1.04
The rate, r = (1.04 - 1) = 0.04
r = 0.04 = (0.04 * 100%) = 4%
Hence, The account balance will increase 4% each year.

Answer:
Antonio is the right one
Answer:
∠ A = 123°
Step-by-step explanation:
The central angle A is equal to the arc that subtends it , so
∠ A = arc DE = 5x - 2
The angles subtended by the radii and tangents of a circle are supplementary
2x + 7 + 5x - 2 = 180 ← Antonio is correct
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25
Then
∠ A = 5 - 2 = 5(25) - 2 = 125 - 2 = 123°

Answers
Answer:
57degrees
Step-by-step explanation:
The triangle is an isosceles triangle, hence m<D = m<E (base angles are equal)
Taking the sum of the angles and equating to 180
5x-4 + 4x+1 + 4x+1 = 180
5x+4x+4x-4+1+1 = 180
13x - 2 = 180
13x = 180 + 2
13x = 182
x =182/13
x = 14
Get m<E
m<E = 4x+ 1
m<E = 4(14)+ 1
m<E = 56+1
m<E = 57degrees
Hence the measure of m<E is 57degrees
