Step-by-step explanation:
Jim's payment is more than Jabu's after four months and Jabu's payment is more than Jim’s after five months.
It is given that Jim’s gym takes a deposit of 150 and a monthly charge of 120.
Let x be the number of months for which both are paying the charges.
Then, Jim's total charge=150+120x.
Now, Jabu’s gym takes no deposit and takes a monthly charge of 150.
Jabu’s gym total charge=150x
Substitute x=4 in the obtained expression to determine the total payment of both after four months.
Jim's total charge=150+120(4)
=150+480
=620
Jabu’s gym total charge=150(4)
=600
So, Jim's payment is more than Jabu after four months.
Substitute x=5 in the obtained expression to determine the total payment of both after five months.
Jim's total charge=150+120(5)
=150+600
=750
Jabu’s gym total charge=150(5)
=750
So, Jabu's payment is more than Jim’s after five months.
Therefore, Jim's payment is more than Jabu's after four months and Jabu's payment is equal to Jim’s after five months.

Step-by-step explanation:
Twenty nine concrete blocks were sampled and tested for crushing strength in order to estimate the proportion that were sufficiently strong for a certain application. Twenty seven of the 29 blocks were sufficiently strong. Use the small-sample method to construct a 95% confidence interval for the proportion of blocks that are sufficiently strong.
Answer:
95% confidence interval for the proportion of blocks that are sufficiently strong
(0.83913 , 1.02293)
Step-by-step explanation:
Step:-1
Given that the sample size 'n' = 29 blocks
Estimate proportion
[tex]p = \frac{x}{n} = \frac{27}{29} = 0.93103[/tex]
Step:-2
95% confidence interval for the proportion of blocks that are sufficiently strong
[tex](p^{-} -Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} } )[/tex]
[tex](0.93103 -1.96 \sqrt{\frac{0.93103(1-0.93103)}{29} } , 0.93103 + 1.96 \sqrt{\frac{0.93103(1-0.93103)}{29} } )[/tex]
(0.93103 - 0.0919 , 0.93103 +0.0919)
(0.83913 , 1.02293)
Final answer:-
95% confidence interval for the proportion of blocks that are sufficiently strong

What is the volume of an 8-inch by 4-inch by 4
1) 2-inch rectangular box?
Answer________ cubic inches
Answer is 128 cubic inches
The volume of the given box is 64 inch³
What is volume?Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m³), a derived unit, is the SI unit of volume. Volume is another word for capacity.
The length, width, and height of a rectangular box are multiplied to get its volume.
As a result, the following formula may be used to determine the volume of an 8 inches by 4 inches by 2 inches rectangular box:
Volume is calculated using the formula LWH.
Volume is =8 * 4 * 2 inches.
64 cubic inches is the volume.
The rectangular box measures 8 by 4 by 2 inches and thus has a volume of 64 cubic inches.

How would you write the equation with a slope of 2/3 and a y-intercept of -3 in slope- intercept form
y=2/3x-2
Explanation:
The equation of a line can be written as y=mx+c
m=slope and c = y-intercept
The point at the x−intercept has coordinates (-3,0)
In y=mx+c
0=2/3(3)+c
0=2+c
-2=c
The equation is y=2/3x-2
Answer:
[tex] y = \frac{2}{3} x - 3[/tex]
Step-by-step explanation:
Slope (m) = 2/3
y-intercept (b) = - 3
Equation of line in slope intercept form is given as:
[tex] y = mx + b[/tex]
Plug the values of m and b in the above equation, we find:
[tex]y = \frac{2}{3} x + ( - 3) \\ \\ y = \frac{2}{3} x - 3[/tex]

A person is standing on the equator of Earth (radius 3960 miles). What are his linear and angular speeds?
Answer:
Linear speed =ωr=2π/86400×3960=11π/120 miles/s.
Step-by-step explanation:
The linear speed and angular speed will be 1036.73 miles / hour and 0.26 radian / hour.
It is given that radius of equator of earth is 3960 miles.
We have to find the linear and angular speeds.
What do you mean by the linear speed ?
The linear speed of a point on the object is equal to the angular speed (ω) multiplied by the distance r.
As per the question ;
radius of equator of earth = 3960 miles
The linear speed will be ;
s = rθ / t
We know that ; at any point of equator would complete 360° or 2π radians revolutions every 24 hours.
So ;
s = (3960 miles × 2π) / 24 hour
s = 330π miles / hour
s ≅ 1036.73 miles / hour
And
The angular speed will be ;
ω = s / r
ω = 1036.73 / 3960 minutes
ω = 0.26 radian/hour
Thus , the linear speed and angular speed will be 1036.73 miles / hour and 0.26 radian / hour.

Step-by-step explanation:
For what value of z would the following system of
equations be true for all real integers?
3x-2y = 14
-12x+8y = 8z
9514 1404 393
Answer:
z = -7
Step-by-step explanation:
The equations will be true for all real integers when they are a dependent set. That will be the case when the second equation is a multiple of the first.
Already, we observe that the ratios of x- and y-coefficients are -4:
-12/3 = -4
8/-2 = -4
The equations will be dependent when the constants have that same ratio:
8z/14 = -4 . . . . desired ratio
8z = -56 . . . . . multiply by 14
z = -7 . . . . makes the equations true for all real numbers
_____
Comment on the question
The system of equations can be made inconsistent (no solutions) or consistent & dependent (infinite solutions) by the choice of z.
However, integer solutions are limited to pairs of the form (2n+2, 3n-4) for integer values of n. The values of x and y are not "all real integers".
Consequently, we have interpreted the question to be asking for the value of z that will make the system of equations have an infinite number of solutions, including both rational and irrational, real and complex values of x and y. They cannot be made to be true for "all real integers" by any choice of z.

Heavy general purpose trucks are often used in pipeline operations. They are built to hold up when carrying or pulling substantial loads, and yet still be suitable for regular highway use. A new truck with appropriate options is purchased for $47,000. It is estimated to have a useful life of 5 years and a salvage value of $2,900 at that time.
Required:
Develop a table showing the depreciation.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Purchase price= $47,000
Salvage value= $2,900
Useful life= 5 years
To calculate the annual depreciation, we need to use the following formula:
Annual depreciation= (original cost - salvage value)/estimated life (years)
Annual depreciation= (47,000 - 2,900) / 5= $8,820
The accumulated depreciation is calculated as follow:
Accumulated depreciation= years of depreciation*annual depreciation
For year 4:
Accumulated depreciation= 8,820*4= $35,280
Finally, the book value is:
Book value= purchase price - accumulated depreciation
Year Annual depreciation Accumulated depreciation Book value
1 8820 8820 38180
2 8820 17640 29360
3 8820 26460 20540
4 8820 35280 11720
5 8820 44100 2900

The times that a cashier spends processing individual customers' orders are independent random variables with mean 4.5 minutes and standard deviation 4 minutes. Find the number of customers n such that the probability that the orders of all n customers can be processed in less than 2 hours, is approximately 0.1. (Round your answer to the nearest integer.)
Answer:
n is approximately 29 customers
Step-by-step explanation:
The given parameters are;
The mean duration of an order, μ = 4.5 minutes
The standard deviation, σ = 4
2 hours = 120 minutes
We get;
The z-score when the probability, P = 0.1 is P(z < 0.53983)
We have;
[tex]z = \dfrac{\dfrac{ \sum X_i}{n} - \mu_{\overline x}}{\dfrac{\sigma}{\sqrt{n} } }[/tex]
Therefore, we get;
[tex]z = \dfrac{\dfrac{120}{n} - 4.5}{\dfrac{4}{\sqrt{n} } } = 0.53983[/tex]
[tex]\dfrac{4}{\sqrt{n} } \times 0.53983 = \dfrac{120}{{n} } -4.5[/tex]
With the aid of a graphing calculator, we get;
81·n²-4320·n + 57600 - 18.6506514278·n = 0
Factorizing gives;
(n - 24.3011921023)·(n - 29.2623961869)·81124141329 = 0
Therefore;
n ≈ 24 or n ≈ 29
Therefore, we take the largest number, n ≈ 29, to make the sample approximately normal
