10 and 6
The ratio of the numbers is 5 : 3 and the numbers are 10 and 6.
Given data:
The first number is x and the second number is y.
The ratio of the two numbers is 5 to 3, which can be expressed as x/y = 5/3.
The sum of the numbers is 16, which can be expressed as x + y = 16.
From the ratio x/y = 5/3:
3x = 5y (equation 1)
From the sum x + y = 16:
x = 16 - y (equation 2)
Now , substitute equation 2 into equation 1 to solve for y:
3(16 - y) = 5y
48 - 3y = 5y
48 = 8y
y = 48/8
y = 6
Substituting the value of y back into equation 2:
x = 16 - y
x = 16 - 6
x = 10
Hence, the numbers are x = 10 and y = 6.

Step-by-step explanation:
There are 4 packs in a regular card deck. Hence, we have four 10s.
The probability of selecting a 10 is thus 4/52 = 1/13
The probability of getting the coin to land on its tail is 1/2.
The probability of getting a 10 and a tail flip = 1/2 * 1/13 = 1/26

Estimate the average number of hours per day spent in using mobile phone by the
college students.
Answers
The estimated average number of hours per day spent using mobile phones by college students is approximately 4.5 hours.
To calculate the mean, we sum up all the individual data points and then divide the total by the number of data points. So, in this case, the sum of the data points is:
5 + 2 + 7 + 5.5 + 3.5 + 4 + 5 + 4.5 + 4 = 40.5.
Next, we divide the sum by the number of data points (which is 9 in this case) to find the mean:
40.5 / 9 ≈ 4.5.
Therefore, the estimated average number of hours per day spent using mobile phones by college students is approximately 4.5 hours.
To know more about average here
#SPJ2
Average = (5 + 2 + 7 + 5.5 + 3.5 + 4 + 5 + 4.5 + 4) / 9
Average = 40.5 /9
Average = 4.5
Average = 4.5 hours.

There are 2 ways to calculate the area of a a regular hexagon.
It is given:
apothem: b = 10.4 yards
side: a = 12 yards
1. The direct way is to use the formula for the regular hexagon without using an apothem:
where
A - the area of the hexagon
a - the side of the hexagon
Therefore:
2. The indirect way is to sketch the hexagon with 3 diagonals and create 6 triangles. Then, it is necessary to calculate the area of one triangle and multiply it by 6. In this triangle, apothem is actually the height.
The area of the hexagon is:
A = 6 · A₁
where:
A - the area of the hexagon,
A₁ - the area of the triangle
where
h - height of the triangle.
Since apothem (b) of the hexagon is the height (h) of the triangle, then:
Thus, the area of one triangle is 62.4 yards.
To calculate the area of the hexagon, we will multiply it by 6:
A = 6 · A₁
A = 6 · 62.4
A = 374.4 yards
In both cases, the result is 374.4 yards.The answer is
