In this figure, we have two rectangular prisms:
1)We calculate the volume of a left rectangular prism:
Data:
length=5 in
width=7 in
height=1 in
Volume₁=length x width x height =(5 in)(7 in)(1 in)=35 in³
2)1)We calculate the volume of a right rectangular prism:
Data:
length=9 in
width=7 in
height=4 in
Volume₂=length x width x height =(9 in)(7 in)(4 in)=252 in³
The volume of the figure below would be the sum of the both rectangular prisms:
Volume of the figure below=Volume₁+Volume₂=35 in³+252 in³=287 in³
Answer: the volume of the figure below would be 287 in³.

True or False: Every Student's t-distribution with n < N, n the number in the sample and N the number in the population, will be less peaked and have thinner tails.
Answers
The statement is false as the Student's t-distribution is actually more peaked and has thicker tails with smaller sample sizes, and it becomes similar to the standard normal distribution as the sample size, and consequently the degrees of freedom, increase.
Explanation:The statement that every Student's t-distribution with n < N, where n is the sample size and N is the population size, will be less peaked and have thinner tails is false. In reality, the t-distribution is more peaked and has thicker tails when the sample size is smaller, which happens due to the reduced degrees of freedom (df).
The shape of the Student's t-distribution is determined by the degrees of freedom, which is n - 1 for a sample size n. As n approaches the population size N, the t-distribution approaches the standard normal distribution. This is further supported by the central limit theorem, which states that as the sample size increases, the sampling distribution of the sample means tends to be normal. Therefore:
The statement in the question is false; the t-distribution becomes less peaked and has thicker tails as the degrees of freedom decrease.
Explanation:The Student's t-distribution is a probability distribution that is used when the sample size is small and the population standard deviation is unknown. It is similar to the standard normal distribution, but has thicker tails and less probability in the center. As the degrees of freedom increase, the t-distribution approaches the standard normal distribution. Therefore, the statement in the question is false. The t-distribution becomes less peaked and has thicker tails as the degrees of freedom decrease.
Walter had 2/4 yard of string. He used 3/6 of it on a school project. How much string did he use?
Answers
2/4 reduces to 1/2
3/6 reduces to 1/2
so he used 1/2 of 1/2 yard
1/2 * 1/2 = 1/4
he used 1/4 yard
[tex]\frac{2}{4} * \frac{3}{6} = \frac{6}{24}[/tex]
Simplify.

A jacket costs $35 and has an 8 percent tax rate. Which expression will find the cost of the tax on the jacket
Answers
$35(8/100)
$280/100

To do this, move the percent sign two places to the left and turn the percent sign into a decimal point.
8% = 0.08
There is a 8% tax on the jacket.
So, 0.08 * 35 is the expression you're looking for.

[tex] \frac{10+x}{5} =3[/tex]
We can multiply both sides by 5 to clear the denominator:

Now we isolate the x by subtracting 10 from both sides.
10+x-10=15-10
x=5

Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the number of nickels in the collection?
ANSWER- 0.1(175-n)+0.05n=13.30
Answers
0.05n+0.1d=13.30 now using d found above in this equation yields:
0.05n+0.1(175-n)=13.30
...
1.5(4-g)+1g=5.5
6-1.5g+g=5.5
6-0.5g=5.5
-0.5g=-0.5
g=1
5.5/4=1.375
So your grid should be:
3oz 1.50 4.50
1oz 1.00 1.00
4oz 1.375 5.50
Answer:
The equation we can use is 0.1(175-n)+0.05 n=13.30
Step-by-step explanation:
Number of Dimes= d
Number of Nickels= n
n+d=175, so d=175-n
The value of the dime is $0.10 and the value of each nickel is $0.05 and the whole collection is worth $13.30, so
0.1 d+0.05 n=13.30
Replacing
0.1(175-n)+0.05 n=13.30 this is the equation we have to use to get the number of nickels.

Step-by-step explanation:
first let's start with a formula.
y = mx + b
m equals the slope and b equals the y intercept.
slope can also be indetified as a rate of change.
so, looking at the graph we can see that the y intercept is (0, 36) or 36 and the rate of change is 3 subtracted.

A television costs $270.25 including 15% tax. How much of cost is the tax
Answers
Final answer:
The tax on the television is $35.25.
Explanation:
To find the amount of tax, we first need to determine the original cost of the television. Since the total cost, including tax, is $270.25, we can set up the equation:
$270.25 = x + 0.15x
Where x is the original cost of the television. Combining like terms, we get:
$270.25 = 1.15x
To solve for x, divide both sides of the equation by 1.15:
x = $270.25 ÷ 1.15
Using a calculator, we find that x is approximately $235.00. Therefore, the tax on the television is:
$270.25 - $235.00 = $35.25

if PA=14 and PD=10 what is the length of PC
Answers
To find the length of PC when PA=14 and PD=10, apply the cosine rule formula in trigonometry.
The length of PC can be calculated using trigonometry and the given information.
Since PA=14 and PD=10, we can use the cosine rule to find the length of PC.Applying the cosine rule formula, PC = √(PA2 + PD2 - 2*PA*PD*cos(θ)).Calculate the length of PC by substituting the values: PC = √(142 + 102 - 2*14*10*cos(θ)).You invest $300 in an account at 7.5% per year simple interest. How much will you have in the account at the beginning of the 11th year
Answers
By investing $300 at a 7.5% per year simple interest rate, the accrued interest over 11 years is $247.50. Adding this to the initial investment, the total in the account at the beginning of the 11th year will be $547.50.
To determine how much you will have in an account at the beginning of the 11th year with simple interest, you can use the formula for simple interest:
Simple Interest (I) = P × r × t
Where:
P is the principal amount ($300)r is the annual interest rate (7.5% or 0.075)t is the time in years (11 years)Let's calculate the simple interest first:
I = 300 × 0.075 × 11I = 247.50So, the interest earned over 11 years is $247.50. Now, add this to the principal amount to get the total amount in the account at the beginning of the 11th year:
Total Amount = Principal + Interest
Total Amount = 300 + 247.50
Total Amount = 547.50

Step-by-step explanation:
We can connect two points of a circle in many ways, as you can see in the picture below.

If the circle has 9 inches of radius the diameter will be 9+9 = 18 inches.
The table shows the estimated number of deer living in a forest over a five-year period. Which type of function best models the data? Write an equation to model the data. Year Estimated Population 0 100 1 79 2 62 3 49 4 39
Answers
We are given the following data:
Year Estimated Population
0 100
1 79
2 62
3 49
4 39
Just by looking at the data we can see that the relationship of year and estimated population is not linear. The decrease in the population does not follow a linear path, that is:
79 – 100 is not equal to 62 – 79
-21 is not equal to -17
Therefore, the relationship must be exponential. Let us find the common ratio by dividing the population in year 1 and year 0:
common ratio, r = 79 / 100 = 0.79
This means that the population decreases by 21% every year.
So the model for this data can be written as:
yn = y0 * r^n
Where,
yn = is the population after n years
y0 = initial population
r = growth rate = decreasing
n = number of years

Step-by-step explanation: We are given to solve the following system of equations:

Let us consider that
[tex]x^2=a,~~~~~y^2=b.[/tex]
So, equations (i) and (ii) becomes
[tex]4a+9b=72~~~~~~~~~~~~~~~~(iii)\\\\a-b=5~~~~~~~~~~~~~~~~~~~~(iv)[/tex]
Multiplying equation (iv) by 4 and then subtracting from equation (iii), we get
[tex](4a+9b)-(4a-4b)=72-4\times 5\\\\\Rightarrow 4a+9b-4a+4b=72-20\\\\\Rightarrow 13b=52\\\\\Rightarrow b=4.[/tex]
From equation (iv), we get
[tex]a-b=5\\\\\Rightarrow a-4=5\\\\\Rightarrow a=9.[/tex]
Therefore,
[tex]a=9~~~~~\Rightarrow x^2=9~~~~~\Rightarrow x=\pm3,\\\\b=4~~~~~\Rightarrow y^2=4~~~~~\Rightarrow y=\pm2.[/tex]
