8. Two alarms ring simultaneously
3am in the morning. The first alarm rings every 20
minutes while the second alarm rings
every hour. What time will the two alarms
ring at the same
time for the third time?​

Answers

3:20 then 3:40 then 4:00 for both
They will meet for a third time at 6am because 20 is one third of 60. So when the first alarm rings three times the second one will also ring. Then since the question is asking when the alarms ring for the third time together you ha e to add three hours to 3am because they always meet on the hour. Hope this helps!

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.

Answers

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

Give your answer in whole people.
ME=8%=0.08
CL=90%=1.645
n=?

Answers

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.

The table below represents a linear function f(x) and the equation represents a function g(x): (See pic)


Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).

Part B: Which function has a greater y-intercept? Justify your answer.

Answers

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

Answers

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.

What is Function?

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).

How do i take questions down like this one?

Step-by-step explanation:

The scores for all high school seniors taking the verbal section of the Scholastic Aptitude Test (SAT) in a particular year had a mean of 490 and a standard deviation of 100. The distribution of SAT scores is bell-shaped.

What percentage of seniors scored between 390 and 590 on this SAT test?

Answers

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]

Answers

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]

( 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
