Kurt will have to save an amount of $496.75 each month.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
Final amount of the account, A = $25,000
Interest rate, r = 0.2% = 0.002
Number of years, t = 4 years
Interest compounded monthly, so n = 12
Annuity can be found using the formula,
Annuity = 25,000 ÷ {[(1 + 0.002)^(12×4) - 1] / 0.002}
= 25,000 ÷ {[(1.002)⁴⁸ - 1] / 0.002}
= 496.75
Hence the amount Kurt needs to save each month is $496.75.

Sixty dash fivesixty-five percent of households say they would feel secure if they had? $50,000 in savings. you randomly select 88 households and ask them if they would feel secure if they had? $50,000 in savings. find the probability that the number that say they would feel secure is? (a) exactly? five, (b) more than? five, and? (c) at most five.
To solve the following problems, we use the binomial probability equation:
P (r) = [n!/(n-r)! r!] p^r q^(n-r)
where,
n = total number of households = 8
r = number of sample
p = probability of success = 65% = 0.65
q = probability of failure = 0.35
A. r = 5
P (r=5) = [8! / 3! 5!] 0.65^5 0.35^3
P (r=5) = 0.28
B. r >5
P (r=6) = [8! / 2! 6!] 0.65^6 0.35^2
P (r=6) = 0.26
P (r=7) = [8! / 1! 7!] 0.65^7 0.35^1
P (r=7) = 0.14
P (r=8) = [8! / 0! 8!] 0.65^8 0.35^0
P (r=8) = 0.03
Therefore total is:
P (r>5) = 0.26 + 0.14 + 0.03 = 0.43
C. r ≤ 5
P (r ≤ 5) = 1 - P (r>5)
P (r ≤ 5) = 1 – 0.43
P (r ≤ 5) = 0.57

Which of the following nonlinear inequalities is graphed below? Picture included below!! PLEASE HELP ASAP!
Answer:
The correct option is A.
Step-by-step explanation:
The general form of an ellipse is
[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]
Where, (0,0) is the center of ellipse, (±a,0) are x-intercepts and (0,±b) are y-intercepts.
From the given graph it is clear that the center of ellipse is (0,0), (±2,0) are x-intercepts and (0,±4) are y-intercepts. So, the equation of ellipse is
[tex]\frac{x^2}{(2)^2}+\frac{y^2}{(4)^2}=1[/tex]
[tex]\frac{x^2}{4}+\frac{y^2}{16}=1[/tex]
The shaded region is inside the ellipse, (0,0) lie in the solution set and the points lie on the ellipse are included in the solution set, therefore the sign of inequality is ≤.
[tex]\frac{(0)^2}{4}+\frac{(0)^2}{16}\leq 1[/tex]
[tex]0\leq 1[/tex]
This statement is true. The required inequality is
[tex]\frac{x^2}{4}+\frac{y^2}{16}\leq 1[/tex]
Therefore, the correct option is A.
A plane flew for 4 hours heading south and for 6 hours heading east. If the total distance traveled was 3,370 miles, and the plane traveled 45 miles per hour faster heading south, at what speed was the plane traveling east?
The plane was traveling at 319 miles per hour heading east. This was determined by setting up equations for the distances covered in both directions, considering the speed difference, and solving for the eastward speed.
To find the speed at which the plane was traveling east, we need to set up two equations based on the given information.
Let's denote the speed of the plane heading east [tex]v_e[/tex] and the speed of the plane heading south [tex]v_s[/tex]. According to the problem, [tex]v_s[/tex] = [tex]v_e[/tex] + 45 mph. We also know that the plane flew south for 4 hours and east for 6 hours, covering a total distance of 3,370 miles.
To represent the sum of distances covered in both directions, we use the equation:
4[tex]v_s[/tex] + 6[tex]v_e[/tex] = 3,370
Substituting [tex]v_s[/tex] with [tex]v_e[/tex] + 45 in the equation yields:
4([tex]v_e[/tex] + 45) + 6[tex]v_e[/tex] = 3,370
By simplifying and solving for [tex]v_e[/tex], we find the speed of the plane traveling east. Let's solve it step by step:
4[tex]v_e[/tex] + 180 + 6[tex]v_e[/tex] = 3,370
10[tex]v_e[/tex] + 180 = 3,370
10[tex]v_e[/tex] = 3,190
[tex]v_e[/tex] = 319 mph
Therefore, the plane was traveling at 319 miles per hour heading east.
For his long long distance phone service Chris pays a $6 monthly fee plus 8 cents per minute. Last month, Chris's long distance bill was $11.52. For how many minutes was Chris billed
total bill would be X=6.00 +0.08m
where m = minutes
X = total bill
so 11.52 = 6.00+0.08m
subtract 6 from each side
5.52 = 0.08m
now divide both sides by 0.08
5.52/0.08 = 69
he was billed for 69 minutes.
A manufacturer knows that their items have a normally distributed lifespan, with a mean of 2.4 years, and standard deviation of 0.7 years. the 8% of items with the shortest lifespan will last less than how many years? give your answer to one decimal place.
To solve this problem, we make use of the z statistic. We are to look for the bottom 8% who has the shortest lifespan, this is equivalent to a proportion of P = 0.08. Using the standard distribution tables for z, the value of z corresponding to this P value is:
z = -1.4
Now given the z and standard deviation s and the mean u, we can calculate for the number of years of the shortest lifespan:
x = z s + u
x = -1.4 (0.7) + 2.4
x = -0.98 + 2.4
x = 1.42 years
Therefore the life span is less than about 1.42 years

Answer: b. [tex]x\geq 0[/tex] , where x is the positive real numbers.
Step-by-step explanation:
We Know that, The Set of all Possible values of independent variable is called Domain of the function.
Since, Exponential graph starting at point (0, 30000),
Thus, the initial value of value of independent variable is 0.
Also, The given exponential function is approaching the x axis as it moves left to right.
Therefore, The Domain must contain the all positive real numbers.
Thus, the Domain of the given function is [tex]x\geq 0[/tex] , where x is the positive real numbers.
Therefore, Option b is correct.
If a boatman rows his boat 35km up stream and 55km downstream in 12 hours and he can row 30km upstream and 44 km downstream in 10hr , then the speed of the stream and that of the boat in still water
To solve this problem, let us assume linear motion so that we can use the equation:
t = d / v
where t is time, d is distance and v is velocity
First let us assign some variables, let us say that the velocity upstream is Vu while Velocity downstream is Vd, so that:
35 / Vu + 55 / Vd = 12 ---> 1
30 / Vu + 44 / Vd = 10 ---> 2
We rewrite equation 1 in terms of Vu:
(35 / Vu + 55 / Vd = 12) Vu
35 + 55 Vu / Vd = 12 Vu
12 Vu – 55 Vu / Vd = 35
Vu (12 – 55 / Vd) = 35
Vu = 35 / (12 – 55 / Vd) ---> 3
Also rewriting equation 2 to in terms of Vu:
Vu = 30 / (10 – 44 / Vd) ---> 4
Equating 3 and 4:
35 / (12 – 55 / Vd) = 30 / (10 – 44 / Vd)
35 (10 – 44 / Vd) = 30 (12 – 55 / Vd)
Multiply both sides by Vd:
350 Vd – 1540 = 360 Vd – 1650
10 Vd = 110
Vd = 11 km / h
Using equation 3 to solve for Vu:
Vu = 35 / (12 – 55 / 11)
Vu = 5 km / h
Answers:
Vu = 5 km / h = velocity upstream
Vd = 11 km / h = velocity downstream

Draw a quadrilateral with the given description
A rhombus with 6-centimeter sides and two 80 degree angles
Answer:
Step-by-step explanation:
By definition, a quadrilateral is a general term for a parallelogram and a rhombus. They are both 4-sided two-dimensional shapes with two sets of parallel sides. However, a rhombus is a special case. It has equal sides. Consequently, all its angles are equal. Therefore, the resultant drawing is alike to what's in the attached picture. But technically, all its sides are equal to 6 cm and all its angles are equal to 80°.

car rental in Thailand cost $35 per day when booked in advance. If rented locally you would be charged 1800 bahts per day. If the exchange rate is 40 bahts equals $1 how much cheaper is it to book in advance
Answer:
advance booking is cheaper by 400 bahts or $10.
Step-by-step explanation:
Car rental cost in advanced booking = $35 per day
and
when the rented locally it is charged = 1800 bahts per day
it is given that,
$1 is equal to 40 bahts.
now,
Car rental cost in advanced booking = 35 × 40
= 1400 bahts
hence, when booking is done advance
the cost is cheaper by 1800 - 1400 = 400 bahts
hence, advance booking is cheaper by 400 bahts or $10.
Mr. Wu is going to stock the concession stand for the Little League playoffs. He knows he will need at least twice as many hamburger buns as hotdog buns. Hamburger buns cost $0.45 each, and hotdog buns cost $0.40 each. He cannot spend more than $60 on buns. If x = the number of hamburger buns and y = the number of hotdog buns, which system of inequalities could be used to determine how many of each kind of bun Mr. Wu should purchase for the stand?
The system of inequalities to determine the number of hamburger and hotdog buns Mr. Wu should purchase is x \\geq 2y for the quantity requirement, and 0.45x + 0.40y \\leq 60 for the budget constraint.
To determine how many hamburger buns (x) and hotdog buns (y) Mr. Wu can purchase for the concession stand, we need to set up a system of inequalities based on the given conditions. Since he needs at least twice as many hamburger buns as hotdog buns, we can express this requirement as an inequality: x \\geq 2y. Additionally, considering the cost of hamburger buns is $0.45 each and hotdog buns are $0.40 each, the total spending should not exceed $60. This gives us a budget constraint inequality: 0.45x + 0.40y \\leq 60. Therefore, the system of inequalities that can be used to determine the number of each kind of bun Mr. Wu should purchase is:
x \\geq 2y0.45x + 0.40y \\leq 60if 3×1=34 2×3=65 6×1=67 5×4=209 then 6×3=

x+y=5
?
Answer : Option A
Explanation:
we can clearly see that from x+ y=5 we can substitute y = 5-x in y = 9x^2
Option B is clearly incorrect x can not be y -5
Option C is incorrect because y can not be 5 +x
Option D is incorrect because its y = 9x^2 not y^2 =9x^2 so y can not be 3x
if its y^2 = 9x^2 then only implies y = 3x
Answer:
Option 1st is correct
[tex]5-x= 9x^2[/tex]
[tex]y = 5-x[/tex]
Step-by-step explanation:
Given the equations:
[tex]y = 9x^2[/tex] .....[1]
[tex]x+y = 5[/tex] .....[2]
We can write equation [2] as:
[tex]y = 5-x[/tex]
Now, substitute this y value in [1] we have;
[tex]5-x= 9x^2[/tex]
Therefore, the system which is equivalent to the given system equation is,
[tex]5-x= 9x^2[/tex]
[tex]y = 5-x[/tex]
