Answer:

C.

Step-by-step explanation:

It's hard to explain, but trust me :)

5 is subtracted by 4 times a number. 4 times a number is 4x, because x is the unknown number. That would be 4x-5

Then, it says that 4x-5 is greater than 8 times a number. Again, 8 times a number is 8x because x is the unknown number.

And remember, > is greater than, and < is less than.

Hopefully you understand this problem for another time.

Answer: 325

Explanation:

Let the number of adult tickets be x

( since there are an unknown amount of tickets for adults, we already know how many student tickets there are)

Let the number of student tickets be x+60

710=x+x+60

710=2x+60

 -60        -60

650=2x

650/2

= 325

Adult tickets=325

Student tickets=385

Answer:

x° = 42°

Step-by-step explanation:

x° = 180° - (70° + 68°) = 42°

Answer:

The price ticket that we know is the adult ticket. The coupon shows that the ticket is good for $28.00. In the redd it shows that you save 4 dollars, so just add 4 to the 28 and the ORIGINAL price of the adult ticket is $32.00.

To find the price of the children's tickets, start with subtracting $28 (this is the price of the adult ticket) from the total of $76 (this is the total number of all the tickets combined).

76 - 28 = 48

Now divide that by 2

48/2 = 24$

So it was $24 per child

Answer:

666

Step-by-step explanation:

From this question,

a = 1-99%

a = 1-0.99

a = 0.01

5% = z(0.05) = 2.58 when we check the standard normal table

Therefore we calculate n as:

n = (z/E)²*p*1-p

Z = 2.58

E = 0.05

P = 0.5

1-p = 0.5

(2.58/0.05)²x0.5x0.5

= 51.6²x0.5x0.5

= 665.64

Therefore n is approximately 666.

Answer:

68°

Step-by-step explanation:

Since, angle subtended on the circumference of the circle is half angle subtended on the center of the circle.

[tex] \therefore m\angle DBR = \frac{1}{2} \times m\angle DAR\\\\

\therefore 34\degree = \frac{1}{2} \times m\angle DAR\\\\

\therefore 34\degree \times 2= m\angle DAR\\\\

\therefore 68\degree = m\angle DAR\\\\

\therefore m\angle DAR=68\degree[/tex]

Answer:

The value is  [tex]P( 390 < X < 590) = 68.3 \%[/tex]    

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 490[/tex]

    The standard deviation is  [tex]\sigma = 100[/tex]

Generally the proportion of seniors scored between 390 and 590 on this SAT test is mathematically represented as

     [tex]P( 390 < X < 590) = P( \frac{390 - 490 }{100} < \frac{\= x - \mu }{\sigma} < \frac{590 - 490 }{ 100} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

    [tex]P( 390 < X < 590) = P( -1 < Z < 1 )[/tex]

=>  [tex]P( 390 < X < 590) = P(Z< 1 ) - P(Z < - 1 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1 and  -1  is  

[tex]P(Z< 1 ) = 0.84134[/tex]

and

[tex]P(Z< - 1 ) = 0.15866[/tex]  

   [tex]P( 390 < X < 590) =0.84134 - 0.15866[/tex]

=> [tex]P( 390 < X < 590) = 0.6827[/tex]

Generally the percentage of seniors scored between 390 and 590 on this SAT test is mathematically represented as

=> [tex]P( 390 < X < 590) = 0.6827 *100[/tex]    

=> [tex]P( 390 < X < 590) = 68.3 \%[/tex]

The 6 oz bottle

Step-by-step explanation:

When you simplify it to see how much per ounce each costs, the 6-oz has the better price.

2.29/6 = 0.381666....

10.19/15 = 0.6793....

the second bottle cost more per ounce, so the 6 oz bottle has the better deal

y=-3x/2

because gradient =-3/2

and u must use formula (y-y1) = m(x-x1)

Answer:

x=1 .................

Answer:

Step-by-step explanation:

A.

slope of f(x) remember that m=rise /run and see how you get from point (0,0) to (1,3) for example

m= rise 3/ run 1= 3

slope of g(x) you find by comparing it to y=mx+b wher m is slope and b is intercept so g(x) slope is m = 7

Slope of f(x) is 3 and slope of g(x) is 7 so g(x) go upward  faster.

B.

again compare g(x) =7x+2 with y=mx+b where b is the y-intercept

g(x) has y-intercept at (0,2)

we can see from the table that at x=0 the y-intecept is 0

f(x) has y-intercept at (0, 0)

g(x) has a greater y-intercept point

Answer:

Step-by-step explanation:

1. g(1) = (1)³ - 5(1) = - 4

2. At x = 11 function g(x) is not defined,

3. h(5) = 2(5) - | 5 - 10 | = 5

4 h( - 10) = 2( - 10)² - 2(- 10) + 1 = 221

5. g(- 1) = - (- 1)² - 5(- 1) + 2 = - 1 + 5 + 2 = 6

6. h(0) = 3(0) - (0)³ = 0

7. g(20) = - √[3(20) - 16] = - 2√11

8. h(- 4) = not defined

The value of each function is shown below.

A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are common in mathematics and are required for the formulation of physical relationships in the sciences.

From the given function we can find the values as:

g(1) = x³ - 5x

g(1) = 1³ -5 = -4

2. For x= 11 the function g(x) is not defined.

3. h(5) = 2x - |x -10|

h(5) = 4

4. h(-10) = 2x²  - 2x + 1

h(-10) = 221

5. g(-1) = -x² -5x + 2

g(-1) = 6

6. h(0) = 3(0) - (0)³

h(0) = 0

7. g(20) = - √[3(20) - 16]

g(20) = - 2√11

8. h(- 4) is not defined for the function h(x).
