According to the U.S. Census Bureau, the total number of households in the state of Indiana is 2,478,846. The number of households with at least one resident who is 65 years of age or younger is 1,885,128. What percentage of Indiana households have at least one resident who is 65 years of age or younger? (Round to the nearest hundredth percent)
Step-by-step explanation:
100% = 2,478,846
1% = 100%/100 = 2,478,846/100 = 24,788.46
how many % are 1,885,128 ?
we need to see how often 1% fits into that amount.
1,885,128 / 24,788.46 = 76.04861294... %
so, the rounded answer is
76.05%
The required percentage of Indiana households that have at least one resident who is 65 years of age or younger is 76.05.
Given that,
According to the U.S. Census Bureau, the total number of households in the state of Indiana is 2,478,846. The number of households with at composition least one resident who is 65 years of age or younger is 1,885,128.
The percentage is the ratio of the composition of matter to the overall of matter multiplied by 100.
Here,
Total population = 2,478,846
The total population of at least one resident who is 65 years of age or younger is 1,885,128.
Required percentage = 1,885,128 / 2,478,846 × 100%
Required percentage = 76.05%
Thus, the required percentage of Indiana households that have at least one resident who is 65 years of age or younger is 76.05.

Find the missing term so that r2 + _____ + 100 forms a perfect square trinomial.
A. 10r B. 20r C. −10r D. −20r
Answer:
B 20r
Step-by-step explanation:
r² + + 100
r² = (r ) ( ) signs are all positive. 100 = (10) (10) last number. so
(r + 10)(r + 10)
r(r+ 10) + 10(r + 10)
r² + 10r + 10r + 100
r² + 20r + 100
If a total of 1100 square centimeters of material is to be used to make a box with a square base and an open top, find the largest possible volume of such a box.
Answer:
Step-by-step explanation:
Let x = base side length
y = side height
volume V = x²y
y = V/x²
surface area
A = x² + 4xy
A = x² + 4x(V/x²)
A = x² + 4V/x
Solving for volume
V = (A - x²)(x/4)
V = ¼(Ax - x³)
a maximum will occur when the derivative equals zero
V' = ¼(A - 3x²)
0 = ¼(A - 3x²)
0 = A - 3x²
3x² = A
3x² = 1100
x² = (1100 / 3)
x = √(1100/3)
V = (A - x²)(x/4)
V = (1100 - √(1100/3))²(√(1100/3)/4)
V = 3,510.56606...
V = 3510.6 cm³
The box height will be half of the base side length.
y = ½√(1100/3)

Mr. Levy has a budget of $18,000. Uniforms for the marching band cost $315 each, and he needs 62 uniforms. He says, "Since 60x$300=$18,000, I can stay within the budget." Do you agree? Explain.
Answer:
No. See explanation below.
Step-by-step explanation:
No.
Since 60 × $300 = $18,000, he would be exactly at budget if he needed 60 uniforms and if each uniform cost $300, but he needs more than 60 uniforms, and each uniform costs more than $315, so the total cost is definitely more than $18,000.
No, Mr. Levy would not be staying within budget.
Sure, 60 · $300 is $18,00, but he didn't take in the other $15 or the 2 extra uniforms.
If he were to do the math correctly, he should have done 62 · $315, which would be $19,530.
If Mr. Levy were to buy all the uniforms and not worry about it because "60 · $300 is $18,000," he would go over the budget by $1,530.

Realtor Elaine Snyderman took a random sample of 12 homes in a prestigious suburb of
Chicago and found the average appraised market value to be $780,000, and the standard
deviation was $49,000. Test the hypothesis that for all homes in the area, the mean appraised
value is $825,000 against the alternative that it is less than $825,000. Use the 0.05 level of
significance
Using the t-distribution, it is found that since the p-value of the test is of 0.0044 < 0.05, it can be concluded that found the average appraised market value is less than $825,000.
The null hypothesis is:
[tex]H_0: \mu = 825000[/tex]
The alternative hypothesis is:
[tex]H_1: \mu < 825000[/tex]
We have the standard deviation for the sample, thus, the t-distribution is used. The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.
[tex]\mu[/tex] is the value tested at the null hypothesis.
s is the standard deviation of the sample.
n is the sample size.
For this problem, the values of the parameters are: [tex]\overline{x} = 780000, \mu = 825000, s = 49000, n = 12[/tex].
The value of the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{780000 - 825000}{\frac{49000}{\sqrt{12}}}[/tex]
[tex]t = -3.18[/tex]
The p-value of the test is found using a left-tailed test, as we are testing if the mean is less than a value, with t = -3.18 and 12 - 1 = 11 df.
Using a t-distribution calculator, it is of 0.0044.
Since the p-value of the test is of 0.0044 < 0.05, it can be concluded that found the average appraised market value is less than $825,000.

An equation is shown below:
6(2x - 11) + 15 = 3x + 12
Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)
Answer:
Part A: First you distribute the 6(2x-11) and simplify. Then, you get the variables on the same side by subtracting 3x. Next, you do inverse operations by adding 51 to both sides and dividing 9 from both sides
Part B: x=7
Step-by-step explanation:
First thing you should do is distribute out the 6(2x-11) to get 12x-66+15=3x+12. then you simplify to get 12x-51=3x+12. Next you need to get both variable on the same side so just to keep positive number to make it easier you will subtract 3x from both sides to get 9x-51=12. now it is simple algebra where you add 51 to both sides of the equation to get 9x=63. Finally, you divide both sides by 9 to get x=7

A bucket holds 4 liters of water. If a ladle can scoop out 1/4 of a liter, how many scoops will it take to empty the bucket?
Answer:
3 scoops will take to empty the bucket because 1 scoop has been taken out of the bucket
Answer:
The answer is 4 scoops.
Step-by-step explanation:
The question states that a ladle can scoop 1/4 of a liter at a time from the bucket, which is taking out a quarter of water from the bucket. Taking 2/4 liters of water from the bucket would be taking half of the water away. Taking another scoop of water out of it would be 3/4, and 4/4 would be taking all of the water out. Therefore, your answer is 4.

A cuboid in which the sum of its dimensions is 9 cm., then the sum of its edge lengths - cm. (18 or 27 or 36 or 45)
The number of sides or edges on a cuboid are twelve, and the sum of the
edges is the sum of the twelve edges.
The sum of the edge lengths = 36 cm
Reasons:
The given parameters are;
The sum of the dimension of the cuboid = 9 cm
Required:
The value sum of the dimension of the edges the cuboid.
Solution:
The dimensions of a cuboid are; Length, l, width, w, and height, h
We get;
l + w + h = 9
The number of times that each dimension appear = 4 times
4 edges with the same length as the height, h
4 edges with the same length as the width, w
4 edges with the same length as the length, l
The sum of the edge lengths is therefore; Sum Edges = 4·l + 4·w + 4·h
Which gives;
Sum Edges = 4·l + 4·w + 4·h = 4 × (l + w + h) = 4 × 9 = 36
The sum of the edge lengths = 36 cm.

What is the z-score of x, when x = 1 and X ~ N (12,3)? Must Show Working
Answer:
=1−12/3≈−3.67
Step-by-step explanation:
The z-score of x = 1, when x ~ N(12, 3), is approximately -3.6667.
To find the z-score of x when x = 1, we'll use the formula for z-score:
z = (x - μ) / σ
Given:
x = 1
μ (mean) = 12
σ (standard deviation) = 3
Substituting these values into the formula, we get:
z = (1 - 12) / 3
Calculating the numerator:
1 - 12 = -11
Dividing the numerator by the denominator:
-11 / 3 ≈ -3.6667
Therefore, the z-score of x = 1, when x follows a normal distribution with a mean of 12 and a standard deviation of 3, is approximately -3.6667.

O $13, 493.54
O $13,000.00
Answer:
$13,493.54
Step-by-step explanation:
We are gonna use the provided formula: A = P(1 + r/m)^mt
A = Final amount (?)
P = Starting amount (10,000)
r = rate (0.03)
m = times applied (12 since it is compounded monthly)
t = years (10)
A = 10,000(1 + 0.03/12)^12·10
I would suggest using a calculator, but let's try to get a little far with this
A = 10,000(1 + 0.0025)^12·10
