Question 2
Mike deposited $3,000 in the first year of a retirement account, and then increased the deposits by $300 each year. The account earned 8.35%. What was the account value after forty years?
The account value after forty years is approximately $489,074,140.57.
What is formula for the future value of an annuity?To calculate the account value after forty years, we need to use the formula for the future value of an annuity:
[tex]FV = P * [(1 + r)^n - 1] / r[/tex]
where FV is the future value, P is the annual payment, r is the interest rate, and n is the number of periods.
In this case, we have:
P = $3,000 in year 1, and then $3,300 in year 2, $3,600 in year 3, and so on
r = 8.35% = 0.0835 (assuming the interest rate is compounded annually)
n = 40 years
To compute the future worth of the annuity, we really want to ascertain the aggregate sum of installments over the 40 years. This should be possible involving the equation for the amount of a number-crunching series:
S = n/2 * [2a + (n-1)d]
where S is the sum, a is the first term, d is the common difference, and n is the number of terms.
In this case, we have:
a = $3,000
d = $300
n = 40
Plugging these values into the formula, we get:
S = 40/2 * [2($3,000) + (40-1)($300)] = $2,340,000
Thus, the aggregate sum of installments more than 40 years is $2,340,000.
We can now enter these figures into the formula for annuity future value:
[tex]FV = P * [(1 + r)^n - 1] / r[/tex]
[tex]FV = $2,340,000 * [(1 + 0.0835)^{40} - 1] / 0.0835[/tex]
FV = $2,340,000 * 209.251
FV = $489,074,140.57
Consequently, after forty years, the account's value is approximately $489,074,140.57.

Around 21.13% of the batteries will final(last) between 90.6 and 109.8 hours.
To unravel this issue, ready to utilize the standard typical conveyance by standardizing the values utilizing the equation:
z = (x - μ) / σ
where
x is the esteem we need to discover the likelihood
μ is cruel(mean), and σ is the standard deviation.
So, for the lower conclusion of the extent, we have:
z1 = (90.6 - 105) / 12 ≈ -1.20
z1 = -1.20
And for the upper conclusion of the extension, we have the:
z2 = (109.8 - 105) / 12 ≈ 0.45
z2 = 0.45
We need to discover the rate of batteries that will final(last) between these two values, which compares to the area under the typical bend between z1 and z2.
Able to utilize a standard ordinary conveyance table or calculator to discover this zone, or we will utilize the properties of the typical conveyance to inexact it.
Since the typical conveyance is symmetric around the cruel, we know that the zone between z1 and z2 is the same as the range between -z2 and -z1 (i.e., the comparing values on the other side of the mean).
So, ready to discover the range between -z2 and -z1, which compares to the rate of batteries that will final between 90.6 and 109.8 hours:
P(-z2 < z < -z1) ≈ P(z < -z1) - P(z < -z2)
Employing a standard typical dissemination table or calculator, we discover:
P(z < -1.20) ≈ 0.1151
P(z < -0.45) ≈ 0.3264
So, the rate of batteries that will final between 90.6 and 109.8 hours is rough:
P(-z2 < z < -z1) ≈ 0.3264 - 0.1151 ≈ 0.2113

If the dimensions of a prism with surface area 42 m^2 and volume 18 m^3 are enlarged by a factor of 4, what is the surface area and volume of the prism?
SA = 2lw + 2lh + 2wh = 42 m^2 ... (1)
And the volume of the original prism is given by:
V = lwh = 18 m^3 ... (2)
If you enlarge the dimensions of the prism by a factor of 4, then the new dimensions will be 4l, 4w, and 4h. The new surface area of the prism will be:
New SA = 2(4l)(4w) + 2(4l)(4h) + 2(4w)(4h)
= 32lw + 32lh + 32wh
= 32(2lw + 2lh + 2wh)
= 32(42)
= 1344 m^2
So, the surface area of the enlarged prism is 1344 m^2.
Similarly, the new volume of the prism will be:
New V = (4l)(4w)(4h)

Angles X and Y are supplementary. Angle X measures 115. 75° and angle Y measures (m − 8)°. Find m∠Y
The measure of angle Y is m - 8 = 72.25 - 8 = 64.25 degrees.
What is the supplementary angle?
Two angles are said to be supplementary if their sum is equal to 180 degrees. In other words, if angle A and angle B are supplementary, then:
A + B = 180.
Since angles X and Y are supplementary, their measures add up to 180 degrees. So we have:
X + Y = 180
Substituting the given values, we get:
115.75 + (m - 8) = 180
Simplifying, we get:
m - 8 = 180 - 115.75
m - 8 = 64.25
Adding 8 to both sides, we get:
m = 72.25

6 to 10 23 23
10 to 12 32 48
The relative frequency of students that are of the 1 to 5 class and are left-handed is 40%.
What is relative frequency?Relative frequency is the ratio of the number of times an event occurs to the number of trials. This can be expressed as a fraction, a percentage, or a proportion.
This can be calculated using the following equation:
Relative Frequency = (Number of Left-Handed Students in 1 to 5 Class / Total Number of Students in 1 to 5 Class) x 100
Relative Frequency = (17 / (17 + 25)) x 100
Relative Frequency = 40%
This calculation shows that 40% of students in the 1 to 5 class are left-handed. This percentage can be rounded to the nearest whole percentage, giving the answer of 40%.
By comparing the relative frequency of left-handed students in the 1 to 5 class to the relative frequency in the other classes, it can be seen that the 1 to 5 class has the highest relative frequency of left-handed students.
This could be due to the developmental stage of students in this age group, as studies have shown that being left-handed is more common in children aged 5 to 10 than in adults.
Alternatively, it could be due to cultural factors, such as left-handed students feeling more comfortable in the 1 to 5 class due to the younger age group.

the health care provider prescribes cefazolin 550 mg intramuscularly to a client. The nurse dilutes a 2-g vial of cefazolin (Ancef) with 3 mL of diluent to yield a volume of 3.2 mL. How many mL should the nurse administer if the physician orders 550 mg IM? Type the correct answer in the blank.
The nurse should administer 0.88 mL of the cefazolin solution for the 550 mg IM dose.
To determine the number of mL to administer for the 550 mg IM dose of cefazolin, follow these steps:
Determine the concentration of cefazolin per mL:
- You have a 2-g (2000 mg) vial of cefazolin that was diluted with 3 mL of diluent, yielding a total volume of 3.2 mL.
- Divide the total amount of cefazolin (2000 mg) by the total volume (3.2 mL) to find the concentration per mL: 2000 mg / 3.2 mL = 625 mg/mL.
Calculate the volume needed for the 550 mg dose:
- Divide the prescribed dose (550 mg) by the concentration per mL (625 mg/mL):
550 mg / 625 mg/mL = 0.88 mL.

To determine the mL to administer for the 550 mg IM order of cefazolin, follow these steps:
1. Calculate the concentration of cefazolin in the solution:
- 2,000 mg (2-g vial) of cefazolin is diluted with 3 mL of diluent, yielding a volume of 3.2 mL.
- Concentration = (2,000 mg) / (3.2 mL) = 625 mg/mL
2. Determine the volume needed for the 550 mg prescribed dose:
- Volume = (Prescribed Dose) / (Concentration)
- Volume = (550 mg) / (625 mg/mL) = 0.88 mL

o determine whether voters would be willing to vote for a tax increase to improve the city's parks, the park commission surveys 500 park users.
Why is this sample likely to be biased?
This sample is likely to be biased because it only includes individuals who use the city's parks, which means it may not represent the entire population of voters who would be affected by a tax increase to improve the parks.
What is sample?A sample is a subset or a smaller group of individuals or 17 that are selected from a larger population to represent the population.
According to question:The park commission's study of 500 park users is likely biassed because it only covers people who use the city's parks. This indicates that the sample does not accurately reflect the full electorate who would be impacted by a tax hike to fund park improvements.
Various people may hold various views regarding whether or not a tax increase is required to develop the parks. For instance, if they don't frequent the parks or have other priorities for their tax money, they might be less likely to approve a tax hike.
If the park commission only conducted surveys of people at specific times of day or in specific locations of the city, the sample may also be skewed. This could omit those who visit the parks at various hours or in various locations around the city.
In order to get accurate and valid results, it's crucial to utilise a representative sample that includes people from different demographic groups. A biased sample can produce results that are erroneous or misleading.
