Enter the values for the highlighted variables to
LekaFEV [45]

Answer:

a = - 1

b = - 9

c = 9

d = 3

e = 3

f = 2

g = 3/2

Step-by-step explanation:

For a;

6 - 2x = - (2x - 6)

For b;

-1 * 9 = - 9

For x ;

3x + (-9) = 3x - 9

3x - 9 = d(x - e)

Factorizing :

3(x - 3)

d = 3 ; e = 3

2x - 6 = f(x - 3)

Factorize :

2x - 6 = 2(x - 3)

3(x - 3) / 2(x - 3)

g = 3/2

The components of a vector are Ax = –10 units and Ay = 8 units. What angle does this vector make with the positive x axis? g
Mandarinka [93]

Answer:

This vector make an angle of 141° with the positive x axis

Step-by-step explanation:

Refer the attached figure

Components of vector :

A_x=-10 \\A_y = 8

We are supposed to find  What angle does this vector make with the positive x axis

tan \theta =\frac{A_y}{A_x}\\tan \theta =\frac{8}{-10}\\\theta =tan^{-1}(\frac{8}{-10})\\\theta =tan^{-1}(\frac{8}{-10})=-38.65^{\circ}

Now ,

\alpha = 180-38.65=141.35^{\circ}

So, this vector make an angle of 141° with the positive x axis

At noodle & company restaurant, the probability that a customer will order a nonalcoholic beverage is .46. Find the probabil
skelet666 [1.2K]

Answer:

0.0021

Step-by-step explanation:

Given:

Probability of ordering a nonalcoholic beverage is, P(N)=0.46

Number of samples are n=10

Now, the complement of event 'N' is not ordering a nonalcoholic beverage.

Therefore, P(\overline N)=1-P(N)=1-0.46=0.54

Now, for a sample of '10' customers, the probability of not ordering a non alcoholic beverage is product of their individual probabilities as all these events are independent events.

Therefore, probability that none of the 10 will order a nonalcoholic beverage is given as:

=[P(\overline N)]^{10}\\\\=(0.54)^{10}\\\\=0.0021

X=7 -2x+10<br> What does this equal?
mote1985 [20]

Step-by-step explanation:

Since X is given to you (in this case, it’s 7), all you have to do is plug it into the equation.

1. -2(7) + 10

When a variable or a number is directly outside a number, it means you should multiply the two numbers, no matter what.

Now that we know this: -2 * 7 = (-14) When a negative is multiplied by a positive, it turns out negative.

2. (-14) + 10: Let’s say (for instance), that I owe 14 dollars to a friend. If I pay 10 of it, how much do I owe my friend? It would be -4 because you’re still in debt, and haven’t payed your friend all of her 14 dollars back.

3. You should come up with an answer of (-4) because of all of the steps given.

If something doesn’t make sense, please make a note of it and tell me. Otherwise, have a splendid day.
