Answer:

$x < - \frac{5}{3}$

Step-by-step explanation:

$x - 7x > 10 \\ subtract \: x \: to \: 7x \\ \\ - 6x > 10 \\ divide \: both \: sides \: by \: - 6 \\ \\ x < - \frac{5}{3}$

The thickness of a protective coating applied to a conductor designed to work in corrosive conditions follows a uniform distribu

pochemuha

Answer:

$P(24< X$

And replacing we got:

$P(24< X$

Step-by-step explanation:

We can define the random variable X as the thickness of a protective coating applied to a conductor designed to work in corrosive conditions. And the distribution for X is given by:

$X \sim Unif (a = 20, b=40)$

And we want to find this probability:

$P(24< X$

And in order to find this probability we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a} , a\leq X \leq b$

And if we use this formula for the probability desired we have:

$P(24< X$

And replacing we got:

$P(24< X$

I WILL MARK BRAINIEST <br> please answer question 5

Marat540 [252]

Answer:

a = 150

Step-by-step explanation:

The sum of the internal angles of an octagon is 1080°.

$4a+4(120)=1080$ (There are four $120^{\circ}$ and 4 $a^{\circ}$ , they sum to 1080°)

$4a + 480 = 1080$

$4a = 600$

$a = 150$

Hope this helps :)

4. Use information in the figure below to find M/_ D

shtirl [24]

Answer:

d

Step-by-step explanation:

Since DF = EF then the triangle is isosceles with base angle being congruent, that is

∠ D = ∠ E , then

∠ D = $\frac{180-133}{2}$ = $\frac{47}{2}$ = 23.5°
