Find the mean 35 40 12 16 25 10

ruslelena [56]

Answer: Mean = 23

Step-by-step explanation:

Given information:

35, 40, 12, 16, 25, 10

Given formula:

$Mean~=~\frac{Sum~of~terms}{Number~of~terms}$

Substitute values into the formula

$Mean~=~\frac{35~+~40~+~12~+~16~+~25~+~10}{6}$

Combine like terms

$Mean~=~\frac{75~+~28~+~35}{6}$

$Mean~=~\frac{103~+~35}{6}$

$Mean~=~\frac{138}{6}$

Simplify the fraction

$\Large\boxed{Mean=23}$

Hope this helps!! :)

Answer:

There are 327,811 doctors.

Step-by-step explanation:

Percentage of female doctors = $16.9$ %

Number of female doctors = $55,400$

Percentage of Male doctors = $100-16.9$ %

= $83.1$ %

So if $55,400$ doctors are represented by $16.9$ how many doctors are represented by $100$ %?

$100$ % represents total number of doctors.

⇒ $\frac{55,400}{16.9} \times100$

=327,810.65

Number of doctors has to be a whole number so we rounf off the number to nearest whole number:

Therefore there are 327,811 doctors.

Whats the value of x and what is the length of side UW

solmaris [256]

We will calculate this by using ratios and because these two triangles are similar, which is very important.

Explanation:

We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.

9 : 21 = 18 : x

x = (21*18)/9

x = 378/9

x = 42.

The correct answer is B. 42.
