You can use sin 40°.
Set up the equation: sin 40° = 16/x
Isolate x: 16/sin 40° = x
Simplify: x = 24.88

So, the answer is F. 24.88

when you multiply a three-digit number by a four-digit number, what is the greatest number of digits the product can have? Expla

lilavasa [31]

Answer:

7 digits

Step-by-step explanation:

When we multiply a two digit number like 17 by another 2 digit

The highest number of digits we can get as answer is 4 digits

This can be seen in the case of 10 * 10

So what this mean is that at any point in time, we can sum the numbers to get the digits

3 + 4 will give 7

And that is the greatest number we can get

Square ABCD has side length a. Half circles with

Inga [223]

The area of the shaded region is $0.215a^2$

<h2>Area of composite objects</h2>

The area of the shaded region is expressed according to the formula:

$A = A_s - A_c$

Get the area of the square As

As = a²

$A_c = \pi (0.5a)^2\\
A_c = 0.785a^2$

Take the difference in the areas

Area of the shaded part = $a^2-0.785a^2\\
$

Area of the shaded part = $0.215a^2$

Hence the area of the shaded region is $0.215a^2$

The ages of a sample of fans at a rock concert are listed. 24, 27, 19, 21, 18, 23, 21, 20, 19, 33, 30, 29, 21, 18, 24, 26, 38, 1

Rudik [331]

Answer:

1. {18, 18 , 19 , 19 , 19 , 20 , 21 , 21 , 21 , 21 , 23 , 24 , 24 , 26 , 27 , 27 , 29 , 30 , 30 , 30 , 33 , 33, 34 , 35 , 38 }

2a) md= 24 b) Q1=20.5 c) Q3= 30 3) Q3-Q1 =9.5 b) 19/48

Step-by-step explanation:

To answer this question the 1st and the 2nd we need to order the data entries. So from ordering from the lowest to the highest value:

1. {18, 18 , 19 , 19 , 19 , 20 , 21 , 21 , 21 , 21 , 23 , 24 , 24 , 26 , 27 , 27 , 29 , 30 , 30 , 30 , 33 , 33, 34 , 35 , 38 }

2. There are 25 entries.

{18, 18 , 19 , 19 , 19 , 20 , 21 , 21 , 21 , 21 , 23 , 24 , 24 , 26 , 27 , 27 , 29 , 30 , 30 , 30 , 33 , 33, 34 , 35 , 38 }

In odd quantities of observations, the Median equally separates it two parts.

md=24

b) To find out the 1st quartile, we can use this way:

$Q_{1}=\frac{i}{4}(n+1)\\ Q_{1}=\frac{1}{4}(25+1)\\ Q_{1}=\frac{1}{4}(26)=6.5$

Then 6.5 is between the 6th and 7th position. Let's find the mean of them, now:

$Q_1=\frac{20+21}{2}= 20.5$

c) Similarly toThe Third Quartile or Upper Quartile

$Q_{3}=\frac{i}{4}(n+1)\\ Q_{3}=\frac{3}{4}(25+1)\\ Q_{1}=\frac{3}{4}(26)=19.5$

The 19th position and 20th position average is: $\frac{30+30}{2} =30$

a) To find the Interquartile Range, we just need to find out the difference of the upper quartile and the lower one: $[tex](Q_3-Q_1)$ Q_3-Q_1[/tex]

(30-20.5)=9.5

b) Interquartile Ratio is given by the quotient of the Interquartile Range over the Median

$\frac{IQR}{md}=\frac{9.5}{24}=\frac{19}{48}$

4) Since the Relative frequency Histogram asked is a one with 7 classes. Let's calculate how many values.

k=1+3.32logn

7=1+3.32logn

6=3.32logn

n≈66

Each class must have an interval of 10 ages, for (91-18)/7≈ 10. Notice the orange line intercepts the midpoint of each interval.
