Answer:

To add fractions, find the LCD (Least Common Denominator) or any common denominator of the fractions. For example, if you wanted to add 1/3+2/7, you find the LCD, which is 21, because 3x7=21, and 3 and 7 are both prime numbers. Now each fraction will have denominators of 21, so we will get 7/21+6/21. To add them together, add the numerators to get 13/21. Find the least common denominator of two fractions and then add the numerators. Hope it helps!

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

Step-by-step explanation:

Step-by-step explanation:

If you want the "root" of the equation...

First get y by itself on one side. You should get y = - x - 8.

Notice that this is the equation of a straight line.

Then let y = 0, and solve for x. You should get x = -8.

So the solution or "root" of the equation is at the point (-8,0)

Answer:

X=0, y=0, x=3

Put the values into the equation. You should get -4,0

-2(-4) –2(0)=8

Complete question is;

In a recent poll, the Gallup Organization found that 45% of adult Americans believe that the overall state of moral values in the United States is poor. Suppose a survey of a random sample of 25 adult Americans is conducted in which they are asked to disclose their feelings on the overall state of moral values in the United States. Find and interpret the probability that exactly 13 of those surveyed feel the state of morals is poor.

Answer:

P(X = 13) = 0.1236 or 12.36%

This means that in 100 trials, approximately 12 of the trials should have exactly 13 of those surveyed feel the state of morals is poor

Step-by-step explanation:

We are given;

Sample size; n = 25

Chance of success; p = 45% = 0.45

This question is a binomial probability distribution problem and the formula is;

P(X = x) = nCx × p^(x) × (1 - p)^(n - x)

probability that exactly 13 of those surveyed feel the state of morals is poor is;

P(X = 13) = (25C13) × 0.45^(13) × (1 - 0.45)^(25 - 13)

P(X = 13) = 5200300 × 0.00003102864 × 0.00076621787

P(X = 13) = 0.1236 or 12.36%

This means that in 100 trials, approximately 12 of the trials should have exactly 13 of those surveyed feel the state of morals is poor

Answer:

The answer is "4 terms".

Step-by-step explanation:

[tex]\sum_{n=1}^{\infty} \frac{(-1)^{n+2} (0.4)^{2n+1}}{(2n+1)!} \ \ \ \ \ error \leq 0.0000001\\\\\\\sum_{n=1}^{\infty} \frac{(-1)^{n+2} (0.4)^{2n+1}}{(2n+1)!} = \frac{-1^{0+2}}{1!}(0.4) + \frac{-1^{1+2}}{3!}(0.4)^3 +\frac{-1^{2+2}}{5!}(0.4)^5+\frac{-1^{3+2}}{7!}(0.4)^7+..\\\\[/tex]

                                  [tex]=0.4 - \frac{0.4^3}{3!} + \frac{0.4^5}{5!} - \frac{0.4^7}{7!}+ \frac{0.4^9}{9!} - \frac{0.4^{11}}{11!}+............\\[/tex]

Note that, alternatively, positive and negative terms are given in the sequence. It is also alternating  

Apply alternative test series:

[tex]\sum_{n=1}^{\infty} (-1)^{n-1} b_n = b_1-b_2+b_3-b_4+b_5-......+(-1)^{n-1} b_n >0\\\\i) b_{n+1}<b_n \ \ \ \ \forall_n \\\\ii) lim_{x\longrightarrow \infity} \ b_n = 0[/tex]

use alternating test method we get:

[tex]\sum_{n=1}^{\infty} \frac{-1^{n-1}}{n^2}\\\\s =0.4 - \frac{0.4^3}{3!} + \frac{0.4^5}{5!} - \frac{0.4^7}{7!}+ \frac{0.4^9}{9!} - \frac{0.4^{11}}{11!}+..\\\\b_5= \frac{0.4^9}{9!} = 0.00000000072 < \frac{1}{10^7} =0.0000001[/tex]

that's why its value is 4 terms

The approximation 0.0000001 within the convergent value of that series the fourth term.

It is the convergent series when it is term decrease in absolute value and approaches the zero limit.

[tex]\sum_{n=1}^{\infty} \dfrac{(-1)^{n+2}(0.4)^{2n+1}}{(2n+1)!}[/tex]

When error ≤ 0.0000001

[tex]\begin{aligned} \sum_{n=1}^{\infty} \dfrac{(-1)^{n+2}(0.4)^{2n+1}}{(2n+1)!} &= \dfrac{(-1)^{0+2}}{1!}(0.4) + \dfrac{(-1)^{1+2}}{3!}(0.4)^{3} + ..............\\\\&= 0.4 - \dfrac{0.4^{3}}{3!} + \dfrac{0.4^{5}}{5!} - \dfrac{0.4^{7}}{7!} + ...............\end{aligned}[/tex]

Now by the alternative test series, we have

[tex]\Sigma _{n=1}^{\infty} (-1)^{n-1} b_n =b_1-b_2+b_3-b_4+....+(-1)^{n-1}b_n > 0\\[/tex]

Then

[tex]i) \ \ b_{n+1} < b_n \ \ \ \ \forall _n\\\\ii) \ \ lim_{x \rightarrow } b_n = 0[/tex]

Then by the alternative test method, we have

[tex]\sum_{n=1}^{\infty} \dfrac{(-1)^{n-1}}{n^{2}} \\\\s = 0.4 - \dfrac{0.4^3}{3!} + \dfrac{0.4^5}{5!} -\dfrac{0.4^7}{7!}+....\\\\b_5 = \dfrac{0.4^9}{9!} = 0.00000000072 < \dfrac{1}{10^7} = 0.0000001[/tex]

Answer:

The required probability (P) =  1/6

Step-by-step explanation:

From the given information:

Suppose two dice are observed; Then the number of outcomes in first dice = 6 i.e (1,2,3,4,5,6) and also the number of outcomes in second dice = 6 as well i.e (1,2,3,4,5,6)

The total number of outcomes of two dices = 6×6 = 36

Now for a sum that is less than 5; their outcomes are [(1,1) ,(1,2) , (1,3) ], [(2,1), (2,2) ], (3,1) = 6 outomes

The total number of outcomes for the sum that is less than 5 = 6

∴

The required probability (P) = Total number of outcomes for the sum that is less than 5 / Total number of outcomes of two dices

The required probability (P) = 6/36

The required probability (P) = 1/6

The probability that the sum is less than 5 is [tex]1\div 6[/tex].

Since two dice are observed.

So the number of outcomes in first dice = 6 i.e (1,2,3,4,5,6) and also the number of outcomes in second dice = 6 as well i.e (1,2,3,4,5,6)

Now

The total number of outcomes of two dices = 6(6) = 36

Now for a sum that is less than 5; their results should be [(1,1) ,(1,2) , (1,3) ], [(2,1), (2,2) ], (3,1) = 6 outomes

So here the probability is

[tex]= 6/36\\\\= 1/6[/tex]

Answer:

At 7.5 hours

Step-by-step explanation:

good luck dude

Answer:

At approximately 5.1 hours, both hosts will charge about the same amount.

Step-by-step explanation:

First, form the equations for both hosts.

X represents hours and the number by itself (75, and 84) are the initial amount.

Host A: y = 12.25x + 75

Host B: y = 10.50x + 84

Now, we would set the equations equal to each other to solve for x, which will help us determine when both hosts will charge the same amount.

12.25x + 75 = 10.50x + 84

Subtract 10.50x and 75 from both sides.

1.75x = 9

Now, divide by 1.75.

x = 5.1428571428571428571428571428571

It says round to the nearest tenth, so we would round to 1 decimal place after the decimal.

x = 5.1

At approximately 5.1 hours, both hosts will charge about the same amount.

Answer:

a) $8018.78

b)   $8056.60

c)  8540 / (1+r)

d)  r = (8540/x) - 1 where "x" is the list price.

Step-by-step explanation:

Recall that the:

total price paid = list price + sales tax

total price paid = list price + percent * list price

a) then, in Washington:

8540 = x + 0.065 * x

8540 = x (1 + 0.065)

8540 = x (1.065)

x = 8540 / 1.065

x = $8018.78

b) in Idaho where the sales tax is 6.0% we do a similar calculation but using the decimal form of the percent 0.06:

8540 = x (1 + 0.06)

8540 = x (1.06)

x = 8540 / 1.06

x = $8056.60

c) If the percent tax is "r" then:

we do:

8540 = x (1+r)

x = 8540 / (1+r)

d) solving for "r" instead of for "x":

8540 = x (1+r)

divide by "x" (the list price):

(8540/x) = 1 + r

subtract 1 from both sides:

(8540/x) - 1 = r
