pav-90 [236]3 years ago
4 0

Answer:

B. 9

Step-by-step explanation:

We know that a full circle should equal 360°, that'll help!

Since the 140°+3x+13 should equal to 180, because that makes the half of the circle it covers, we know how to set up our equation!

It should look like this:

3x+13=40

ISOLATE YOUR VARIABLE:

- Subtract 13 from both sides

NEXT, CONTINUE ISOLATING:

3x=27

- Divide by 3 from both sides.

FINALLY:

You will get X=9!

A company produces optical-fiber cable with a mean of 0.6 flaws per 100 feet. What is the probability that there will be exactly
Mars2501 [29]

Answer:

P(X = 4) =0.133

Step-by-step explanation:

From the question we are told that:

Mean \x=0.6/100

Flaws f=4

Distance  d_2=1000ft

Generally the equation for Poisson mean lambda over 1000 is mathematically given by

\lambda=0.6*1000/100  

\lambda = 6

Therefore

P(X = 4) = {e^-\lambda * \lambda^{\=x}} {{\=x}!}

P(X = 4) =\frac{ e^{-6} * 6^4}{ 4!}

P(X = 4) =0.133

If f(x)=3x+10x and g(x)=4x-1 find (f-g)(x)
oksano4ka [1.4K]

Answer:

(f - g)(x) = 9x + 1

Step-by-step explanation:

Step 1: Write out functions

f(x) = 3x + 10x = 13x

g(x) = 4x - 1

Step 2: Find (f - g)(x)

(f - g)(x) = 13x - (4x - 1)

(f - g)(x) = 13x - 4x + 1

(f - g)(x) = 9x + 1

The boundary line on the graph represents the equation 5x + 2y = 6. Write an
BartSMP [9]

Answer:

The inequality representing the shaded area is y < 3 - 2.5·x

Step-by-step explanation:

The given equation of the graph is 5·x + 2·y = 6

Therefore, we have;

2·y = 6 - 5·x

y = 6/2 - 5/2·x

y = 3 - 2.5·x

Given that the graph is represented by a shaded region on the left and lower side of a broken line, the inequality relationship for the graph is that of a lesser than area inequality with a symbol of < and the inequality for the graph can be represented as follows,

y < 3 - 2.5·x.
