Answer:

X=140

Step-by-step explanation:

<em>Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees</em>

<em>The attachment you are showing us shows that we already know two angles</em>

<em>(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360. </em>

<em />

X+70+60+90=360

X=360-70-60-90

X=140

Add.<br> (8y + 6) + (4y + 5)<br> Submit
Inga [223]

Answer:

12y + 11

Step-by-step explanation:

To add them you would add like terms. That means you would add those with y together and those without together.

8y + 4y + 6 + 5 = 12y + 11

If you want to solve for y, subtract 11 from both sides then divide both sides by 12.

Lockheed Martin, the defense contractor designs and build communication satellite systems to be used by the U.S. military. Becau
Nana76 [90]

Answer:

P(52

And we can find this probability with this difference:

P(-0.851

And if we use the normal standard distribution or excel we got:

P(-0.851

Step-by-step explanation:

Let X the random variable that represent the time required to construct and test a particular component of a population, and for this case we know the distribution for X is given by:

X \sim N(60,9.4)  

Where \mu=60 and \sigma=9.4

We want to find this probability:

P(52

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

Using this formula we got:

P(52

And we can find this probability with this difference:

P(-0.851

And if we use the normal standard distribution or excel we got:

P(-0.851

In your top dresser drawer are 6 blue socks and 10 grey socks, unpaired and mixed up. One dark morning you pull two socks from t
pishuonlain [190]

Answer:

D) 0.500

Step-by-step explanation:

Blue Socks = 6

Grey socks = 10

Probabilities to find :

Since there are a total of 16 socks, the probability of both socks being blue is  

Probability(blue) = (\frac{6}{16} ) \frac{5}{15} =\frac{30}{240} =\frac{1}{8}

The probability of both being grey is  

Probability(grey)  =(\frac{10}{16} ) \frac{9}{15} =\frac{90}{240} =\frac{3}{8}

(Note: After 1 sock is picked , next sock drawn would have a different probability as 1 sock is already picked so it would be 1 minus the total socks available of that color)

The probability two socks match:

Probability(blue) + Probability(grey) = \frac{1}{8} + \frac{3}{8}  = \frac{4}{8}  =\frac{1}{2} = 0.500
