Answer:

x = 5

Step-by-step explanation:

These triangles are similar, so they are in proportion to each other. Because of this we can say $\frac{2.5}{3.5}$ (the lengths of the vertical sides) = $\frac{x}{7}$ (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.

Answer:

The value is $\mu_n = 73.6$

Step-by-step explanation:

From the question we are told that

The total number of students is $N = 25$

The number of student that took exam in class is n = 24

The number that took make up exam is k = 1

The average score of the first 24 students is $\mu = 74$

The standard deviation is $\sigma = 8.9$

The average score of the student who took make up test is $\= x = 64$

Generally the new average is mathematically represented as

$\mu_n = \frac{( n * \mu ) + \= x }{N}$

$\mu_n = \frac{( 24 * 74 ) + 64 }{25}$

$\mu_n = 73.6$
