The manufacturer of a smart watch claims that individuals who pay attention to how many steps they take per day will inadvertently take more steps per day than individuals who pay no attention to how many steps they take per day. to investigate this claim, the manufacturer conducts a study to estimate the difference in the mean number of steps taken by those that pay attention to how many steps they take per day and those that do not. to do so, 40 volunteers are recruited. half of the volunteers are randomly assigned to receive a smart watch and are taught how to use it to track their steps. the other half of the volunteers are given a wristband to wear, but are not informed that the wristband is tracking their steps. the volunteers are monitored for 30 days. the mean and standard deviation of the number of steps taken per day are computed for each group. here are the data:
The confidence interval for the difference in the mean number of steps is; 1596 ± 2.861√[(1580²/20) + (2350²/20)]
What is the confidence Interval?The given data is;
n x⁻ Sₓ
Pay attention 20 10,244 1,580
Do not pay attention 20 8.,648 2,350
We are given;
Significance level; α = 0.1
Using Excel with the function, we have: TINV(0.01,19);
Critical value is; t = 2.861
The margin of error can now be represented by the illustration:
Margin of error = t√[(s₁²/n₁) + (s₂²/n₂)]
Thus, the confidence interval for the difference in the mean number of steps taken by all people like these that do and do not pay attention to the number of steps they take per day using df - 19 is:
1596 ± 2.861√[(1580²/20) + (2350²/20)]

Calculate the energy stored in a spring when it is compressed 5mm by a 60n force
If a 60-N force is compressing the spring a distance of 5 mm = 0.005 m, then by Hooke's law, the spring has constant k such that
60 N = k (0.005 m) ⇒ k = 12,000 N/m
Then the spring is storing
1/2 (12,000 N/m) (0.005 m)² = 0.15 J

Bmx company has one employee. fica social security taxes are 6.2% of the first $137,700 paid to its employee, and fica medicare taxes are 1.45% of gross pay. for bmx, its futa taxes are 0.6% and suta taxes are 5.4% of the first $7,000 paid to its employee.
The BMX tax for situation A, B and C are respectively calculated as; $282.3, $327.6 and $1600.4.
How to Calculate Social Security taxes?We are given;
When the FICA Social Security = 6.2% of the first $128,400
Then FICA Medicare = 1.45% of gross pay.
Also, FUTA = 0.6%
Then SUTA = 5.4% of the first $7,000 paid
Now, Gross Pay through August 31 -----Gross Pay for September
A ⇒ $5,100 ⇒ $2,200
B ⇒ 2,300 ⇒ $2,400
C ⇒ 122,700 ⇒ 8,600
In case of A;
FICA is calculated by multiplying the tax rate by the corresponding amount;
FICA social security tax = $2,200 * 0.062 = $136.4
FICA Medicare = $2,200 * 0.0145 = $31.90
FUTA and also SUTA are calculated by multiplying the excess amount by the respective tax rate.
FUTA taxes = ($7,000 - $5,100) * 0.006 = $11.40
SUTA taxes = ($7,000 - $5,100) * 0.054 = $102.60
BMX tax in situation A = $136.4 + $31.90 + $11.40 + $102.60
BMX Tax = $282.3
In case B;
The gross pay is multiplied by the respective tax rate in this situation because the employee has not reached $7,000 in wages.
FICA social security tax = $2,400 * 0.062 = $148.8
FICA Medicare = $2,400 * .0145 = $34.80
FUTA taxes = $2,400 * 0.006 = $14.40
SUTA taxes = $2,400 * 0.054 = $129.6
BMX tax in situation B = $148.8 + $34.80 + $14.40 + $129.6
BMX Tax = $327.6
In case of C;
The maximum amount of wages subject to social security tax is $128,400. Thus;
FICA social security tax = ($128,400 - $122,700) * 0.062 = $353.40
FICA Medicare: $8,600 * 0.0145 = $1247.00
Total taxes for BMX = $353.40 + $1247.00 = $1600.4

Cooper and his children went into a bakery and where they sell cupcakes for $2.50 each and donuts for $1.50 each. cooper has $40 to spend and must buy a minimum of 18 cupcakes and donuts altogether. if cooper decided to buy 7 cupcakes, determine the maximum number of donuts that he could buy. if there are no possible solutions, submit an empty answer.
Answer: He can buy a maximum of 15 donuts
Explanation: If he bought 7 cupcakes costin $2.50 each then you would multiply 2.50 by 7 which would give you $17.50
then you subtract 17.50 from 40 which gives $22.50 left to use for donuts
then you know you need to have a minimum 18 cupcakes and donuts together so we multiply 1.50 x 11 for the remaining 11 donuts you need and that leaves you with six dollars then if you multiply 1.50 x 4 it gives you the remaining 6 dollars you need so the max number of donuts you may buy is 15

The quotient of a number 8.4x10⁹ and a number n results in 5.6 x 10^27, with the value of n is 1.5×10⁻¹⁸.
What is the quotient of a number?Quotient is the resultant number which is obtained by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,
[tex]q=\dfrac{a}{b}[/tex]
Here, (a, b) are the real numbers.
The two number given in the problem are, 8.4x10⁹ and n. The quotient when first number is divided with second is 5.6 x 10^27. Thus,
[tex]\dfrac{8.6\times10^9}{n}=5.6\times10^{27}[/tex]
Rearrange the equation for n as,
[tex]n=\dfrac{8.6\times10^9}{5.6\times10^{27}}\\n=\dfrac{8.6\times10^{9-27}}{5.6}\\n=1.5\times10^{-18}[/tex]
