What Is The Value Of X?

Answers

Answer 1

Answer:

31 degrees

Step-by-step explanation:

149 + 149 = 298

360 - 298 = 62

62 / 2 =31

Answer 2

Answer:

61 degrees

Step-by-step explanation:

you know that there is a strait line which is equal to 180. So if you subtract 149 from 180 you get 31 which is the angle included with x. therefore you subtract your total number, which is 92 by 31 and you get 61 degrees

The results of a recent survey indicate that the average new car costs $23,000 with a standard deviation on $3,500. The prices of the car are normally distributed. a. If someone buys a car for $32,000, what proportion of cars cost an equal amount or more than this? b. If someone buys a car for $16,000, what proportion of cars cost an equal amount or more than this?

Answers

Answer:

(a) 0.0051

(b) 0.9773

Step-by-step explanation:

Let X = prices of the car.

It is provided that [tex]X\sim N(23,000, 3,500^{2})[/tex].

(a)

Compute the value of P (X ≥ 32000) as follows:

[tex]P(X\geq 32000)=P(\frac{X-\mu}{\sigma}>\frac{32000-23000}{3500})[/tex]

                       [tex]=P(Z>2.57)\\=1-P(Z<2.57)\\=1-0.99492\\=0.00508\\\approx 0.0051[/tex]

Thus, the proportion of cars cost an equal amount or more than $32,000 is 0.0051.

(b)

Compute the value of P (X ≥ 16000) as follows:

[tex]P(X\geq 16000)=P(\frac{X-\mu}{\sigma}>\frac{16000-23000}{3500})[/tex]

                       [tex]=P(Z>-2)\\=P(Z<2)\\=0.97725\\\approx 0.9773[/tex]

Thus, the proportion of cars cost an equal amount or more than $16,000 is 0.9773.

A - 5g + 0.75 <_ 15, 13 games
B - 0.75g + 5 <_ 15, 14 games
C - 0.75g + 5 <_ 15, 13 games
D - 5g + 0.75 <_ 15, 14 games

Answers

Answer:

C

Step-by-step explanation:

It is 75 cents a game plus 5 dollars admission. You should automatically subtract 5 dollars for admissions. That would give you ten dollars. You would just multiply how many games by how much they cost.

(You can also find the number of games first, and then solve the two inequalities that match that number backwards)

Janet bought same bars of choclate to share equally with her friends. she bought between 35 and 50 bars altogether. if she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over. If she shares the bars equally with 6 friends she will have 5 bars left over. How many bars of chocolate did she buy?

c.46

Its letter d.48 hope i helped you , but im not sure..

For the conditions to be fulfilled number of chocolate bars Janet bought is 35.

What is an equation?

An equation is a statement in form of numbers and variables that both sides are equal.

Janet bought the same bars of chocolate to share equally with her friends and it is between 36 and 50.

There are two possible cases,

Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'A'.

(i)  If she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over,

∴ N = 7A + 7...(i).

(ii) If she shares the bars equally with 6 friends she will have 5 bars left over,

Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'B'.

∴ N = 6B + 5...(ii)

Now, we have to equate these two equations,

7A + 7 = 6B + 5.

7A = 6B - 2.

A = (6B - 2)/7.

From here we have to find such integer value of B which also makes the value of A an integer and also when we put the values of either A or B in our equations it should lie between 35 and 50.

So,

A = (6B - 2)/7.

When B = 5 then A = 4. Or when B = 12 the A = 10.

But the B = 12 and A = 10 is inadmissible.

Now, we'll put the value of A or B in eqn (i) or (ii).

Which results in N = 35.

So, the number of chocolate bars she bought is 35.

(5x+6) over 2 = 3 (4x+12)

Answers

x= -66/19

Multiply 2 on both sides:

2*(5x+6)/2=3(4x+12)*2

Simplify:

5x+6=24x+72

Subtract 6 from both sides:

5x+6-6=24x+72-6

Simplify:

5x=24x+66

Subtract 24x from both sides:

5x-24x=24x+66-24x

Simplify:

-19x=66

Divide both sides by -19

-19x/-19=66/-19

Simplify:

x= -66/19

The sum of three consecutive even integers is 126. Let x represent the first integer, x + 2 represent the second integer, and x + 4 represent the third integer.

Which equation can be used to find the first integer?




3x + 126 = 2x + 6

3x + 6 = 126

2x + 6 = 126

3x = 2x + 6

Answers

Answer:

3x + 6 = 126

Step-by-step explanation:

If you add all of them

x + x+2 + x+4 = 126

simplify the left-side

3x+6=126

subtract 6 from both sides and you get

3x = 120

divide both sides by 3

x=4
