Solve for x.<br> −7≥13−5x

Sergio039 [100]

Answer:

$=>x\geq 4$

Step-by-step explanation:

Given inequality is $−7\geq13−5x$

Simplifying:

$5x\geq13+7$

$=>5x\geq20$

$=>x\geq \frac{20}{5}$

$=>x\geq 4$

Hence the solution for the given inequality is represented by $=>x\geq 4$

This means that the original inequality will be true only for those values of x which are greater than or equal to 4.

10% of 180 is 18, so over 2 years that is 20%, so 36 dollars.

Find the length of the unknown side. Round your answer to the nearest tenth.

Paraphin [41]

Answer:

<em>The correct option is: 11.5</em>

Step-by-step explanation:

Suppose, the length of the unknown side is $x$

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and $x$ .

As the given triangle is right angle triangle, so <u>using Pythagorean theorem</u>, we will get.........

$8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5$

<em>(Rounded to the nearest tenth)</em>

So, the length of the unknown side is 11.5

A manufacturing process makes rods that vary slightly in length but follow a normal distribution with mean length 25 cm and stan

Galina-37 [17]

Answer:

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = 0.1251

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given mean of the Population = 25cm

Given standard deviation of the Population = 2.60

Let 'x' be the random variable in normal distribution

Given x=22

$Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15$

<u><em>Step(ii):</em></u>-

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = P( Z<-1.15)

= 1-P(Z>1.15)

= 1-( 0.5+A(1.15)

= 0.5 - A(1.15)

= 0.5 - 0.3749

= 0.1251

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = 0.1251
