Answer:

∠CDF= 70°

Step-by-step explanation:

there's an easier way to do this which is adding the angles ∠EDG and ∠GDF and then subtracting that from 180° but, checking your work in the same process is a little more work.

First, I'd like to find ∠ADB.

  1. 85°+70°= 155°
  2. 180°-155°= 25°
  3. ∠ADB= 25°

Second, add all the angles together.

  1. 70°+50°+60°+85°+25°= 290°
  2. 360°-290°= 70°

Which expression has exactly three terms? Select all the expressions that apply.
irga5000 [103]

The answer is expressions D, E, and G.

In algebra, a ‘term’ usually means the different parts of an expression that are separated by + and - signs.

Options A and B only have 1 term, an x or y³, so these are incorrect.

Option C has 1 term as well, ‘xyz’, because they are all multiplied together which makes it one term.

D and E both have 3 terms each, but F has 4 unique terms so this is incorrect also.

G has 3 unique terms, x³, x^4, and 7x, so this is correct.

When H is expanded, you will end up with more than 3 unique terms, so this is incorrect.

I hope this helps!

Alex has a price of fabric that is 56 inches long and 3 inches wide. He cuts it into pieces that are each 7 inches long and 1 in
devlian [24]
Each is 7 long and the whole piece is 56 so we can make 8 down the length and each is 1 wide and the whole things is 3 so that makes 3 across. we multiply these to get 8*3= 24

Suppose calls are arriving at a telephone exchange at an average rate of one per second, according to a Poisson arrival process.
antoniya [11.8K]

Answer:

Explanation has been given below

Step-by-step explanation:                    

a) inter arrival times are exponentially distributed with mean 1/n , where n = rate = 1/sec.                                                                              

  probability distribution function is F(t)=n*exp(-n*t).  

reference to any kth packet and the (k-1)th packet

the answer is = integration of F(t).dt with limits 0 to 2 = 1 - exp(-2*n) = 1 - exp(-2)  

b)  t=5 , P(q) = exp(-5)*(5)^q/factorial(q)  

probability of fourth call within t=5 seconds is =  

that is P(4)   P(5)   ......  = 1 - ( P(0)   P(1)   P(2)   P(3) ) ;  put the values and get the answer.  

c) number of calls/rate =  4/n = 4 seconds

PLEASE HELP ASAP

You have that:

 1. By definition, a binomial is a polynomial formed by two terms. 
 2. A quintic binomial is a binomial of degree 5. This means that its highest exponent is 5.
 3. Keeping this on mind, you must identify which binomial has degree 5.
 4. As you can see, the expression <span>3x^5+2 is a binomial, because it has two terms and the highest degree is 5.
 5. Thefore, the answer is: </span>3x^5+2
