A study of 1000 randomly selected flights of a major airline showed that 820 of the flights arrived on time. What is the probability of a randomly selected flight not arriving on time?
a. 50/1
b. 9/50
c. 41/50
d. 1/4
Answer:
b. 9/50
Step-by-step explanation:
•the probability of the selected flight arriving on time: 820/1000 = 0.82
•find the probability of the flights not being selected by subtracting 0.82 from 1.00: 1.00-0.82=0.18
•now you look for the answer that equals to 0.18
50/1 =50 nope
9/50 =0.18 yes
41/50 =0.82 nope
1/4 = 0.25 nope
Find the future value of an ordinary annuity of $200 paid quarterly for 6 years, if the interest rate is 10%, compounded quarterly. (Round your answer to the nearest cent.)
Answer:
Future value is $1543.12
Step-by-step explanation:
From the question, present value = $200, rate = 10%, years = 6.
So that future value of ordinary annuity can be calculated by,
FV = [tex]\frac{A{[(1+r)^{n} - 1]}}{r}[/tex]
where: FV is the future value, A is the annuity, r is the rate, and n is the number of years.
FV = [tex]\frac{200[(1+0.1)^{6}-1] }{0.1}[/tex]
= [tex]\frac{200[1.1^{6}- 1] }{0.1}[/tex]
= [tex]\frac{200*0.771561}{0.1}[/tex]
= [tex]\frac{154.3122}{0.1}[/tex]
FV = $1543.122
The future value of the ordinary annuity is $1543.12.

Are the angles 117 in degrees and 477 in degrees coterminal?
Answer:
Yes, they are coterminal.
Step-by-step explanation:
Coterminal angles are angles that are in multiples of -360 degrees or +360 degrees away from the initial angle.
Therefore, the easiest way to check if an angle is coterminal is set up an equation.
[tex]x + 117 = 477\\\\360 + 117 = 477\\\\477 = 477 \ \checkmark[/tex]
We get a true statement, which means that 117 is a coterminal angle of 477 and 477 is a coterminal angle of 117.
We can also determine the value in radians.
[tex]\displaystyle117 \times \frac{\pi}{180}\\\\\frac{117\pi}{180} = \frac{13\pi}{20}[/tex]
117° in radians is [tex]\displaystyle\frac{13\pi}{20}[/tex]. Coterminal angles for radians are multiples of [tex]2\pi[/tex], either negative or positive.
However, we also need to determine the value of 477 in radians too.
[tex]\displaystyle477\times\frac{\pi}{180}\\\\\frac{477\pi}{180} = \frac{53\pi}{20}[/tex]
So, if we add [tex]2\pi[/tex] to [tex]\frac{13\pi}{20}[/tex]:
[tex]\displaystyle\frac{13\pi}{20} + 2\pi\\\\\frac{13\pi}{20} + \frac{40\pi}{20} = \frac{53\pi}{20}[/tex]
Therefore, even in radians, 477° is an angle coterminal to 117°.
You are given 117°.
To find angles that are coterminal with 117°, we do the following:
117° + 360° = 477°
117° - 360° = 243°
As you can see, when we added 117° to 360°, we got 477°.
To answer your question, YES.
You now know that 117° and 477° are coterminal angles.
Keep in mind that 477° is not the only coterminal angle to 117°.
May u please help me ill give out the brainly
Answer:
The answer is B.
Step-by-step explanation:
In order to solve this problem, you need to combine like terms, which in this case, are the x's. So, if you add the numbers with the x's together, you get 3x + 12y. The 12y remains untouched because there are no other terms with the same variable.

3n + 14= --4 What is the answer
Answer: n = -6
Step-by-step explanation:
3n+14=-4
Subtract 14 from both sides.
3n+14-14=-4-14
Simplify
3n=-18
Divide both sides by 3
3n/3 = -18/3
n=-6
what is the sqaure root of (x-3/7) divided by 12x+7 divided by 76.3x?
Answer:
[tex]\sqrt{\frac{3x}{3} } + \frac{10}{109} x[/tex]
Step by step:
[tex]\sqrt{x-\frac{3}{7}[/tex] = [tex]\sqrt{\frac{49x-21}{7} }[/tex]
[tex]\sqrt{\frac{49x-21}{7} }[/tex] ÷ 12x+7=[tex]\sqrt{\frac{7x-3x}{12}} + 7[/tex]
[tex]\sqrt{\frac{7x-3x}{12}} + 7[/tex] ÷ 76.3x = [tex]\sqrt{\frac{3x}{3} } + \frac{10}{109} x[/tex]

Let C(t) be the amount of U.S. cash per capita in circulation at time 1. The table, supplied by the Treasury Department, gives values of C(t) as of June 30 of the specificd year. Interpret and estimate the value of C'(1980).
Answer:
Following are the solution to this question:
Step-by-step explanation:
C'(t) was its time, in years, or t shift of cash per unit. That C'(1980) meaning, therefore, becomes the change of cashier's population to t = 1980.
They could either use t = 1970 or t = 1990 to approximate the C'(1980) price. When using t = 1970:
[tex]C'(1980) = \frac{[C(1980) - C(1970)]}{[1980 - 1970]}\\\\[/tex]
[tex]= \frac{(571 - 265)}{10}\\\\ = \$ \ 30.6 \\[/tex]
t = 1990:
[tex]C'(1980) = \frac{[C(1980) - C(1990)]}{[1980 - 1990]}[/tex]
[tex]= \frac{(571 - 1063)}{ -10} \\\\= \$ \ 49.2[/tex]

Explain to a Friend Taylor wants to buy a bicycle
that costs $48.75 and a helmet that costs $18.30. She works for her
mom after school to earn the money. If Taylor is paid $5.50 per hour,
will she be able to buy the bicycle and helmet after working 9 hours?
Explain to a friend
Answer: No
Step-by-step explanation:
First add the 48.75 and 18.30 together.
second multiply 5.50 by 9
she would only earn 49.50 so she won’t be able to buy the bike and helmet

Question
Find the multiplicative inverse of 0.13.
Answer:
multiplicative inverse of 0.13 is -100/30
The required inverse of 0.13 is 1 / 0.13.
Given that,
To find the multiplicative inverse of 0.13.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
The inverse of the particular number is that number when it is multiplied by the number that gives the unit. i.e. ab = 1
Here,
Let the required multiplicative inverse be x,
The product of a number and its multiplicative inverse is equal to 1
So,
0.13*x = 1
x = 1 / 0.13
Thus, the required inverse of 0.13 is 1 / 0.13.

Answer:
Use the formula
a n = a 1 r n − 1
to identify the geometric sequence.
a n = 1.5 ⋅ 2 n − 1
Answer:
n x 2 = x
Step-by-step explanation:
This is the answer because:
1) 1.5 x 2 = 3
2) 3 x 2 = 6
3) 6 x 2 = 12
Therefore, the pattern in this sequence is n x 2 = x

1.66666666667.everlasting 6s
Hope this helps :D
Answer:
1.666......
( 1.6 recurring).
Step-by-step explanation:
As both numbers are multiples of 10 it makes it a bit easier to divide both by 10 to give 25 and 15. This will give the same result as 250/150.
Now do a long division , 25 divided by 15:
1 .66 <----------- 25 / 15 = 1 . 1*15 goes below the 25.
-------------------------
15 ) 25.0
15 <---------- subtract 25 - 15 = 10
100 <- bring down the zero(after the decimal point) & append to 10
90 < 15 divides into 100 6 times to give 90 . Place 6 above line.
100 < subtract 100 - 90 to give 10 then add 0
90 < as before 100/15 = 6 to give 6*15 = 90
If you carry on as above you'll see that we get 1.6666... and we could go on for ever. This is a recurring decimal and is usually written as 1.6 with a bar above the 6.
