Answer:

x=45.57^{\circ}

Step-by-step explanation:

Given that,

Hypotenuse, H = 10

Base = 7

We need to find the value angle x. The relation between Hypotenuse, Base and the angle x is given by :

\cos\theta=\dfrac{\text{Base}}{\text{Hypotenuse}}\\\\\cos\theta=\dfrac{7}{10}\\\\\theta=\cos^{-1}(\dfrac{7}{10})\\\\\theta=45.57^{\circ}

So, the value of x is 45.57^{\circ}.

Which statistic is a measure of how data are dispersed in a population and can be used to give context to larger data sets
OLEGan [10]

Answer:

standard deviation

Step-by-step explanation:

The standard deviation is defined as the measure of how spread out the numbers are in a given population. In other words, statistics refers to the amount of the dispersion or variation of a set of given values.

It is denoted by the Greek letter sigma, σ.

Thus the standard deviation is the measure of how dispersed the data are in the population which can be used to provide context to a larger data sets.

Let line $l_1$ be the graph of $5x + 8y = -9$. Line $l_2$ is perpendicular to line $l_1$ and passes through the point $(10,10)$.
SashulF [63]

Answer:

m + c = - 4.4

Step-by-step explanation:

Line 1 is given by the equation 5x + 8y = -9, ⇒ y = - \frac{5}{8} x - \frac{9}{5} ........(1) {In slope-intercept form}

If line 2 is perpendicular to the line 1 then the equation of line 2 will be  

y = \frac{8}{5} x + c  ........ (2), where c is a constant. {Since the product of the slopes of two perpendicular straight line is -1}

Now, the line 2 passes through the point (10,10).

So, from equation (2), we get,

c = y - \frac{8}{5} x = 10- \frac{8 \times 10}{5} = - 6

Therefore, the equation of line 2 will be y = \frac{8}{5} x - 6

This equation is in y = mx + c form where m = \frac{8}{5} = 1.6 and c = - 6

Hence, m + c = 1.6 - 6 = - 4.4 (Answer)
