Find the volume of a pyramid with a square base, where the side length of the base is
10.6
in
10.6 in and the height of the pyramid is
12.3
in
12.3 in. Round your answer to the nearest tenth of a cubic inch.
Answers
Answer:
V = 460.68
Step-by-step explanation:
V=(lwh)/3
Volume = (1/3) * base area * height
In this case, the base of the pyramid is a square with a side length of 10.6 inches, so the base area can be calculated as:
Base area = side length * side length
Let's calculate the base area first:
Base area = 10.6 in * 10.6 in
Next, we'll substitute the values into the volume formula:
Volume = (1/3) * (10.6 in * 10.6 in) * 12.3 in
Calculating this expression will give us the volume of the pyramid. Rounding the answer to the nearest tenth of a cubic inch will provide the final result.

While there were about 3,000,000 people (about the population of Arkansas)
who visited the zoo last year, the number of people who visited in each
month was different. For example, people are more likely to visit the zoo in
July than they are in January. For that reason, the zoo raises its prices during
the months when there are a lot of visitors (peak season) and lowers its
prices during the months when there are not as many visitors (off season).
During peak season the zoo has about 1,800,000 visitors. Write an
expression to show how much money would be made during peak season
where p is the price of one peak season ticket.
The zoo wants to sell tickets in the off season for half of the price of tickets
in the peak season. Write an expression to show how much money would be
made during the off season where p is the price of one peak season ticket.
To break even the zoo needs to make at least how much money they spent
on the animals. Write and solve an inequality to find out how much the price
of one peak season ticket should be where p is the price of one peak season
ticket. How much should one off season ticket be?
Answers
Money made during peak season = 1,800,000 * p
1. Expression for money made during peak season:
During peak season, the zoo has about 1,800,000 visitors. To calculate the money made during peak season, we multiply the number of visitors by the price of one peak season ticket (p):
Money made during peak season = 1,800,000 * p
2. Expression for money made during the off season:
The zoo wants to sell tickets in the off season for half the price of tickets in the peak season. Therefore, the price of one off season ticket would be p/2. To calculate the money made during the off season, we multiply the number of visitors by the price of one off season ticket:
Money made during the off season = 1,200,000 * (p/2) = 600,000 * p
3. Inequality for breaking even:
To break even, the zoo needs to make at least as much money as they spent on the animals. Let's represent the amount spent on animals as A. The money made during peak season plus the money made during the off season should be greater than or equal to the amount spent on animals:
1,800,000 * p + 600,000 * (p/2) ≥ A
Simplifying the inequality:
3,600,000p + 300,000p ≥ 2A
3,900,000p ≥ 2A
Solving for p:
p ≥ (2A) / 3,900,000
This determines the minimum price of one peak season ticket to break even.
The price of one off season ticket would be half the price of one peak season ticket, so the off season ticket should be (p/2).

Amir drove from Jerusalem to the lowest place on Earth, the Dead Sea.
His altitude relative to sea level (in meters) as a function of time (in minutes) is graphed.
What was Amir's altitude at the beginning of the drive?
Answers
The equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is: y=-12x+360.
What is Straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point.
First of all let's write the slope-intercept form of the equation of a line, which is:
y=mx+b
where m is the slope and b is y intercept.
So we just need to find m and b to solve this problem.
Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:
m=-12
Negative slope because Amir is descending. So:
y=-12x+b
To find b, we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point (30,0
). Therefore, substituting this point into our equation:
y=-12x+b
0=12(30)+b
0=-360+b
b=360
Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:
y=-12x+360.
Therefore the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is: y=-12x+360.

Gretta is saving for retirement. She deposits $125 each month at 6% annual interest for 35 years. According to her calculations, at the end of 35 years, she should have $178,088.79 in her account. How much of this did Gretta contribute and how much of this is interest?
Answers
Answer:
Gretta's Contribution = $52,500
Interest = $125,588.79
Step-by-step explanation:
Gretta contributes $125 each month, for 35 years. Therefore, to find the amount she contributed, we multiply those pieces together (12 months in each year).
125 x 12 x 35 = $52,500
Therefore, over the 35 years, Gretta contributed $52,500.
If there was $178,088.79 in her account, and she contributed $52,500, then the rest is interest.
$178,088.79 − $52,500 = $125,588.79
There was $125,588.79 in interest earned on Gretta's account.

Using the .05 criterion of significance, the critical value needed to reject the null hypothesis is 2.03. If the standard error of the difference is 2.0, what should the researcher decide and what error might be made?
A) Retain the null hypothesis—Type I error.
B) Retain the null hypothesis—Type II error.
C) Reject the null hypothesis—Type I error.
D) Reject the null hypothesis—Type II error.
Answers
The researcher should always consider the probability of committing a Type I error when designing an experiment.
The level of significance is a measure of the probability of committing a Type I error.
So, option C (Reject the null hypothesis—Type I error) is the correct answer.
The researcher should Reject the null hypothesis - Type I error.
The researcher should Reject the null hypothesis if the computed value of a test statistic exceeds the critical value, i.e. the critical value needed to reject the null hypothesis.
The computed value of the test statistic is -2.53. It falls in the rejection region, i.e., beyond the critical value.
Thus, the researcher can reject the null hypothesis.
So, option C (Reject the null hypothesis—Type I error) is the correct answer.
Note: The Type I error is a type of error that occurs when a researcher falsely rejects the null hypothesis.

Method 1 Method 2
Sample mean 85 83
Sample s.d. 3 2
Required:
Test whether method 1 was more successful than method 2 at the 1% level.
Answers
Answer:
Since the calculated value of t =4.629 falls in the critical region t> 2.355 we reject the null hypothesis and conclude that method 1 was more successful than method 2 at the 1% level.
Step-by-step explanation:
Applying two sample t test as both methods are independent
The null and alternate hypotheses are
H0: u1= u2 against the claim Ha: u1> u2
The significance level is 0.01 and the critical region is t > t∝( n-1)
The degrees of freedom is calculated using the formula
υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1
This formula is used when the the variances are unequal.
So as we do not know anything about variances we assume they are unequal.
The calculated degrees of freedom is 132
The critical region is t > 2.355 for one tailed test.
The test statistic is
t= x1`- x2`/ √s1²/n1 + s2²/n2
t= 85-83/ √3²/75+ 2²/60
t= 2/ 0.432
t= 4.629
Since the calculated value of t =4.629 falls in the critical region t> 2.355 we reject the null hypothesis and conclude that method 1 was more successful than method 2 at the 1% level.

From the concept of direct proportion, y = 65, x = 39 and x = 15, y = 25.
What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
Let, y = kx.
From the table,
5 = 3k.
k = 5/3.
Now, When x = x and y = 65.
65 = (5/3)x.
x = 39.
Again, When x = 15, y = y.
y = (5/3)15.

This question is incomplete, that's why we add another question in the attached file. Please find it.
P = \(\$ \ 1300\) and effective per year is = interest rate per year = 7.2
Total \(\$ \ 1300\) due after 8 years is P+PRT:
\(\to 1300(1+0.072 \times 8)\\\\\to 1300(1+ 0.576)\\\\\to 1300(1.576)\\\\\to \$ \ 2048.8\)
\(\to Total \ X = \$ \ (7000-2048.8) \\\\\)
\(= \$ \ 4951.2 \\\\= X(1 +0.072 \times 5)\\\\=1.36 X \\\\\)
The number of dollars is X \(= \frac{4951.2}{1.36} = \$ \ 3640.58\)
