A measure of center<span> is a value at the </span>center<span> or middle of a </span>data set. Graphically, the center<span> can be viewed as the "balance point" of the display. Algebraically, the most common ways to find the </span>center<span> are with the mean, median, or mode. Mean is the average or sum of all </span>data<span> points divided by the number of points.</span>

The center<span> of a data set is a single number that we can use to stand in for the whole data set. You can usually think of it as a "typical" value. We usually use </span>mean<span> or </span>median<span> for the center. The median is often a better "typical" value if the distribution is skewed (that is, grossly asymmetrical).</span>

Answer:

The Value of $a=\frac{15}{4}$ .

Step-by-step explanation:

We have Named the figure please find the attachment for your reference.

Given:

PR = y

QR = a

RS = b

PS = z

PQ = x

QS = 15

∠P = 90°

∠R = 90°

∠Q = 60°

∠S = 30°

We need to find the Value of 'a'.

Solution:

Now we know that:

In Δ PQS

∠P = 90°

∠S = 30°

Now we know that;

$sin\ \theta = \frac{opposite\ side}{Hypotenuse}$

$sin \ S= \frac{PQ}{QS}$

Substituting the given values we get;

$sin\ 30\°=\frac{x}{15}$

Now we know that;

$sin\ 30\° = \frac12$

So we can say that;

$\frac{1}{2}=\frac{x}{15}\\\\x=\frac{15}{2}$

Now In Triangle PQR.

∠R = 90°

∠Q = 60°

So we can say that;

$Cos \theta = \frac{adjacent \ Side}{Hypotenuse}\\$

$Cos\ Q = \frac{QR}{PQ}$

Substituting the given values we get;

$cos 60\°= \frac{a}{x}$

Now we know that;

$cos 60\°= \frac12$

$x=\frac{15}{2}$

So substituting the values we get;

$\frac{1}{2}=\frac{a}{\frac{15}{2}}$

By Using Cross Multiplication we get;

$a= \frac{1}{2}\times\frac{15}{2}\\\\a=\frac{15}{4}$

Hence The Value of $a=\frac{15}{4}$ .

Lola's age is 14 more than 6 times Juan's age. The sum of their ages is 35. How old is each?

earnstyle [38]

35 - 14 = 21

3 * 6 = 18

3.5 * 6 = 21

Thus Juan is around the age of 3.5 and Lola is 31.5 I believe

Im not quite sure however I think this is the answer, I hope it helps ^-^
