Answer:
Step-by-step explanation:
40,000= x (1+ .04)^12
the future value of the account =40,000
the amount invested at the end of each period =x because we do not know
the interest rate per period = 0.04 because 8% compounded semiannually is 4% per 6 months or written as decimals 0.04
(1+.04) because you gain interest so you add to the 100% of your money 4%
the number of periods = 12 because in 6 years we have twelve 6 months periods
[tex]x= \frac{40,000}{1.04^{12} }[/tex]

x^2 - 25 = 0
A. x = -5
В. no solutions
C. x = 5
D. x = 5; x = -5
Answer:
D. x = 5; x = -5
Step-by-step explanation:
x^2 - 25 = 0
Add 25 to each side
x^2 - 25+25 = 0+25
x^2 = 25
Take the square root of each side
sqrt(x^2) = sqrt(25)

The midpoint of a line segment from P1 to P2 is (-5,2). If P1 = (-1,7), what is P2?
Hope it helps you!
-miraculousfanx-
Answer:
p2 = (-9 , -3)
Step-by-step explanation:
let p2 be (a , b)
given :
p1(-1 , 7) = (x1 , y1)
p2(a , b) = (x2 , y2)
using midpoint formula:
midpoint = (x1 + x2/2 , y1 + y2/2)
(-5 , 2) = (-1 + a/2 , 7 + b/2)
Now , compare corresponding elements
-5 = -1 + a/2
-5*2 = -1 + a
-10 = -1 + a
-10 + 1 = a
-9 = a
2 = 7 + b/2
2*2 = 7 + b
4 = 7 + b
4 - 7 = b
-3 = b
therefore p2 = (-9 , -3)
The volume of a sphere is 904.32 mm3. What is the approximate volume of a cone that has the same height and a circular base with the same diameter? Use 3.14 for π and round to the nearest hundredth.
Answer:
[tex]V_c=452.16\ mm^3[/tex]
Step-by-step explanation:
Given that,
The volume of a sphere is 904.32 mm³.
The volume of a cone that has the same height and circular base with the same diameter is:
[tex]V_c=\dfrac{1}{3}\pi r^2 \times 2r=\dfrac{2}{3}\pi r^3[/tex]
The volume of a sphere with the same radius is:
[tex]V_s=\dfrac{4}{3}\pi r^3=2\times \dfrac{2}{3}\pi r^3[/tex]
So, the volume of sphere is :
[tex]V_c=\dfrac{V_s}{2}\\\\V_c=\dfrac{904.32 }{2}\\\\V_c=452.16\ mm^3[/tex]
So, the volume of the cone is [tex]452.16\ mm^3[/tex].

A store is giving out cards labeled 1 through 10 when customers enter the store. If the
card is an even number, you get a 15% discount on your purchase that day. If the card is an odd
number greater than 6, you get a 30% discount. Otherwise, you get a 20% discount. The table
shows the results of 500 customers. What is the relative frequency for each discount? Use pencil
and paper. If the manager of the store wants approximately half of the customers to receive the
20% discount does this seem like an appropriate method? Explain.
Step-by-step explanation:
The relative frequency for a 15% discount is 52.1%.
What is a relative frequency?The relative frequency is the quotient of a particular frequency divided by the total number of frequencies.
Given:
A store is giving out cards labeled 1 through 10 when customers enter the store.
If the card is an even number, you get a 15% discount on your purchase that day.
The subgroup for even numbers = 2, 4, 6, 8, 10
The subgroup frequency = 56 + 50 + 54 + 49 + 54 = 263
The total frequency = 500
The relative frequency = 263/500 = 0.521 = 52.1%
Therefore, 52.1% is the relative frequency.

The population of interest: Male RCCC students.
Sample size: 31.
The sample mean: 69.68 inches.
Median: 69 inches.
Mode: 70 inches.
Range: 11 inches.
Standard deviation: 3.32 (rounded to 2 decimal places).
Variance: 11.02 (rounded to 2 decimal places).
We have,
Mean:
To find the mean, we sum up all the heights and divide by the total number of data points (31 in this case):
Mean = (70 + 70 + 70 + ... + 75) / 31
Mean ≈ 69.68 inches
Median:
The median represents the middle value in the dataset when arranged in ascending order. Since the dataset has an odd number of values (31), the median will be the value in the middle position when ordered:
Median = 69 inches
Mode:
The mode represents the value(s) that occur most frequently in the dataset. In this case, the mode is the height that appears most often:
Mode = 70 inches
Range:
The range is calculated by subtracting the minimum value from the maximum value in the dataset:
Range = Maximum height - Minimum height
Range = 75 - 64 = 11 inches
Standard Deviation (σ):
To find the standard deviation, we can use the formula that involves finding the difference between each value and the mean, squaring those differences, averaging them, and taking the square root:
Standard Deviation (σ) ≈ 3.32 (rounded to 2 decimal places)
Variance (σ²):
The variance is the square of the standard deviation.
We can square the value of the standard deviation to find the variance:
Variance (σ²) ≈ 11.02 (rounded to 2 decimal places)
The height dataset (in inches) for the 31 male RCCC students is as follows:
1 70

If the number of orders at a production center this month is a Geom(0.7) random variable, find the probability that we'll have at most 3 orders.
Answer: 0.973
Step-by-step explanation:
The probability mass function of geometric distribution is
[tex]f(x)=(1-p)^{x-1}p,\ \ \ x=1,2,3,...[/tex], p= probability of success on a trial.
As per given, we have
p=0.7
The probability that we'll have at most 3 orders [tex]P(X\leq3)=P(x=1)+P(x=2)+P(x=3)[/tex]
[tex]=(1-0.7)^{1-1}(0.7)+(1-0.7)^{2-1}(0.7)+(1-0.7)^{3-1}(0.7)\\\\=0.7+0.21+0.063\\\\=0.973[/tex]
hence, the required probability = 0.973
The probability that we'll have at most 3 orders will be "0.973".
According to the question,
→ [tex]x \sim Geometric (p)[/tex]
here,
p = 0.7
then,
→ [tex]P(X=x) = (1-p)^{x-1}\times p[/tex]
By putting the given values, we get
[tex]= (1-0.7)^{x-1}\times 0.7[/tex]
hence,
The probability that we'll have at most 3 orders will be:
→ [tex]P(X \leq 3)=P(X=1)+P(X=2)+P(X=3)[/tex]
[tex]=0.7+0.21+0.063[/tex]
[tex]=0.973[/tex]

Population of others=10000-(6400+1100+1000)=1500
Population of Caucasians used the Internet for e-mail=86% of 6400
Population of Caucasians used the Internet for e-mail=[tex]\frac{86}{100}\times 6400[/tex]
Population of Caucasians used the Internet for e-mail=5504
Population of African-American used the Internet for e-mail=77% of 1100
Population of African-American used the Internet for e-mail=[tex]\frac{77}{100}\times 1100=847[/tex]
Population of Hispanics used the Internet for e-mail=77% of 1000
