You have 5 cards on the deck. The exercise has reposition, i.e. you put the card back into the deck before picking the next one, so the total number of cards is always 5.
all possible outcome = 5
Divisor of 6 = 3, 6
Probability of picking a divisor of 6 = 2/5
Number less than 5 are : 3 and 4 = 2/5
The intersection between both events is equal to the product of both probabilities since the events are independent.
The probability of picking a divisor of 6 and then picking a number less than 5 is:
P(divisor of 6) and P(no.less than 5) = 2/5 * 2/5 = 4/25

Since, it follows from trigonometric ratios that;
Sin theta = opposite/hypothenuse
Cos theta = adjacent/hypothenuse
It therefore follows that;
Cos(m∠ABC) = 6.3/9.8Sin(m∠ABC) = 7.5/9.8Therefore, the measure of angle ABC can be determined using any of the formulas above;
m∠ABC = cos-¹(6.3/9.8)m∠ABC = sin-¹(7.5/9.8)Therefore the two expressions which can be used to find m∠ABC are;

Please calculate Federal Income Tax, Social Security Tax, Medicare Tax, State Tax & Local tax. Please show work.
The deductions for the taxes are given as follows:
Federal Income Tax: $4,626.27.Social Security Tax: $1,860.Medicare Tax: $435.State Tax: $600.Local Tax: $450.What are his deductions?To calculate the taxes, we have to consider his gross pay, which is given in the text as follows:
Gross pay = $30,000.
The Federal Income Tax for people in his income range is of $1,027.50 plus 12% of the amount over $10,275, hence:
Federal Income Tax = 1027.50 + 0.12 x (30000 - 10.275) = $4,626.27.
The Social Security tax is of 6.2% of his salary, hence:
Social Security Tax = 0.062 x 30000 = $1,860.
The Medicare tax is of 1.45% of his salary, hence:
Medicare Tax = 0.0145 x 30000 = $435.
The State Tax is of 2% os his salary, hence:
State Tax = 0.02 x 30000 = $600.

Write a cosine function that has an amplitude of 3, a midline of 5 and a period of 3/4. .
A cosine function is said to have an amplitude of 3, a midline of 5, and a period of 3/4.
It is required to write the cosine function.
Recall that the standard form of a cosine function is:
[tex]y=a\cos(bx+c)+d[/tex]Where a is the amplitude, 2π/b is the period, c is the horizontal shift, and d is the midline or vertical shift.
Equate the given period to 2π/b and solve for b:
[tex]\begin{gathered} \frac{2\pi}{b}=\frac{3}{4} \\ \Rightarrow3b=8\pi \\ \Rightarrow\frac{3b}{3}=\frac{8\pi}{3} \\ \Rightarrow b=\frac{8\pi}{3} \end{gathered}[/tex]Hence, substitute a=3, b=8π/3, and d=5 into the standard form of the cosine function:
[tex]y=3\cos(\frac{8\pi}{3}x+c)+5[/tex]Since it is not given that the cosine function has a horizontal shift, substitute c=0 to get the required function:

Considering the normally distributed variable, the proportion/percentage are given as follows:
a) Proportion of serves faster than 121 mph: 0.16.
b) Percentage of serves between 109 and 133 mph: 84%.
Normal DistributionThe z-score of a measure X of a variable that has mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by the following equation:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure represented by X is above or below the mean of the distribution, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X in the distribution.As stated in the problem, the mean and the standard deviation of the serve speeds are given as follows:
[tex]\mu = 115, \sigma = 6[/tex]
The proportion of serves faster than 121 mph is one subtracted by the p-value of Z when X = 121, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (121 - 115)/6
Z = 1
Z = 1 has a p-value of 0.8413.
1 - 0.8413 = 0.1587, which is the desired proportion.
The proportion of serve speeds between 109 and 133 mph is the p-value of Z when X = 133 subtracted by the p-value of Z when X = 109, hence:
X = 133:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (133 - 115)/6
Z = 3
Z = 3 has a p-value of 0.9987.
X = 109:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (109 - 115)/6
Z = -1
Z = -1 has a p-value of 0.1587.
0.9987 - 0.1587 = 0.84, hence the percentage is of 84%.

-5, 0, 9, 22, ___, ___
The next two terms of the first quadratic sequences are 37 and 49.
The next two terms of the second quadratic sequences are 39 and 60.
What are the next two terms?A quadratic sequence is a sequence in mathematics where the second difference between consecutive terms in the sequence is the same
The first step is to determine the relationship between the terms in the quadratic sequence.
The difference between 9 and 13 = 13 - 9 = 4
The difference between 19 and 13 = 19 - 13 = 6
The difference between 27 and 19 : 27 - 19 = 8
It can be seen that the first difference between the terms in the sequence quadratic sequence increases by 2.
The difference between the fourth term and the fifth term would be 8 + 2 = 10
Fifth term = 27 + 10 = 37
The difference between fifth term and the sixth term would be 10 + 2 = 12
37 + 12 =49
The first step is to determine the relationship between the terms in the quadratic sequence.
The difference between 0 and -5 : 0 - -5 = 5
The difference between 0 and 9 = 9 - 0 = 9
The difference between 9 and 22 = 22 - 9 = 13
Based on the first difference between the consecutive terms in the digit, it can be seen that the first difference increase by a value of 4.
The difference between the fourth term and the fifth term would be : 13 + 4 = 17
Fifth term = 22 + 17 = 39
The difference between fifth term and the sixth term would be 21 ( 17 + 4)
