Answer:

a = 105 dollars and c = 60 dollars.

Step-by-step explanation:

multiply 105 by 60 to get 6,300

divide 6300 by 105 for a. its 60.

Reversing for children or c, its 105.

In this case, 6300 tickets were sold total. that's just total though.

3-3 = 0

The absloute value of 0 = 0

Hope that helps

Answer:

I am pretty sure it is 0

Step-by-step explanation:

The reson is because if you subtract 3-3 you get 0 and the absolute value to 0 is 0

Answer:

If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.

4 hours at 60 miles per hour = 4*60 = 240 miles

6 hours at 65 miles per hour = 6*65 = 390 miles

This is a total of 630 miles.  There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.

Answer:

  $1.90

Step-by-step explanation:

Let n represent the cost of a notebook. Jenna's purchase is ...

  4n +3(n -1.15) = 9.85

  7n - 3.45 = 9.85 . . . . . simplify

  7n = 13.30 . . . . . . . . . . add 3.45

  n = 1.90 . . . . . . . . . . . . divide by 7

The cost of a notebook is $1.90.

Additional comment

The cost of a folder is 1.90 -1.15 = 0.75. The total purchase is ...

  4(1.90) +3(0.75) = 7.60 +2.25 = 9.85

Answer:

1/(6^3)

Step-by-step explanation:

Each roll of the die constitutes a separate event.

These three events are independent.

The probability of rolling a 2 on the first throw is 1/6, since there is only one '2' among the six numbers on the die.

Because each roll is independent of the others, the probability of rolling a

2                                                              1

on all three rolls is (1/6)(1/6)(1/6), or -----------

                                                              6^3

4. yes because you will get 5/8

Answer:

The answer is $56

Step-by-step explanation:

100% is 20, and 80% of 20 is 16. So you just have to add 16+20=36.That was this month.Then you add 20 +36 to combine the months.Therefore getting your answer.

For the proportion you write 80/100+x/20

Answer:

50, 40, 30, 250, 350

Step-by-step explanation:

1/2 = 0.5, 0.5 x 100 = 50 (0.5 -> 5 -> 50)

2/5 = 0.4 (10 / 5 [the denominator] = 2, 0.2 x 2 [the numerator] = 0.4), 0.4 x 100 = 40 (0.4 -> 4 -> 40)

3/10 = (10 / 10 [the denominator] = 1, 0.1 x 3 [the numerator] = 0.3), 0.3 x 100 = 30 (0.3 -> 3 -> 30)

5/2 = 2.5 (2 1/2), 2.5 x 100 = 250 (2.5 -> 25 -> 250)

7/2 = 3.5 (3 1/2), 3.5 x 100 = 350 (3.5 -> 35 -> 350)

Note: I'm not sure if I understand the question completely, but I changed the fraction into a decimal and multiplied it by 100. Not sure what it means by "Divide fraction".

Answer:

According to the question , firstly we have to divide the fraction and then convert them into percentage

So , let's do it :-

Answer:

1. Marcia

2. (I do not understand what this question is asking)

3. Marcia's estimation is closer

4. 690 people per year

Step-by-step explanation:

1. Marcia's estimation has a greater number of people because he estimated 600 people per year, while Adam estimated 2% of 12,500 (250 people per year).

2. (I do not understand what this question is asking)

3. marcias guess was 600 (600x50+12,500 = 42,500. 42,500 - 35,400 = 7,100) while Adam's guess was 250 per year (250x50+12,500 = 10,400). Therefore, Marcia's guess was closer to 35,400.

4. If Marcia adjusted her answer so that the population in Burbville was ACTUALLY going to be 34,500, she would need to adjust her estimation to 690 people per year.

Hope this helps! So sorry I couldn't understand question 2!

Answer:

The second one

Step-by-step explanation:

Note that he can spend a MAXIMUM of $40 meaning that he can either spend less than or exactly 40 dollars. So if we are creating an inequality the inequality sign must face $40 and it can be equal to 40 therefore we know the inequality must start off with 40≥ or end with ≤40

The movie ticket cost 10$

The amount of money that can be spent on food can be represented by d

the amount of money that can be spent on food plus the cost of the ticket (10) must be equal to or less that 40

Therefore 10 + d ≤ 40

The answer is the second one

Answer:

B. 8.6 cm

Step-by-step explanation:

For angle α, x is the opposite leg.

z is the hypotenuse.

sin α = opp/hyp

sin 27° = x/(19 cm)

x = 19 cm × sin 27°

x = 8.6 cm

Answer: B. 8.6 cm

Answer

49/15

Step-by-step explanation:

because 1/3 of a 10m is 10/3 which is about 3.3 repeating

and 6 3/5 minus 10/3 is 49/15 which is also 3 4/15.

Answer:

The answer is 14

Answer:

B. 30 - (2×3)

C. 40 - 4(3+1)

E. 6×6 - 4×3 = 24

Step-by-step explanation:

B. 30 - (2×3)

30 - 6 = 24

C. 40 - 4(3+1)

40 - 4×4 = 40 - 16 = 24

E. 6×6 - 4×3 = 24

36 - 12 = 24

Hope this helps :)

Have an awesome day!

Answer:

A:    (3 x 4) + (2 x 6)       = 24

B:    30 - (2 x 3)              = 24

C:    40 - 4 x (3 + 1)         = 24

D:    20 + 2 + 1 + 1          = 24

E:     (6 + 6) + (4 x 3)       = 24

I played this game with my math teacher once

Answer:

If I am correct, the answer should be C

Step-by-step explanation:

The expected value of the red marker will be selected is 420. Then the correct option is C.

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

[tex]\rm X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]\rm P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value of X is:

[tex]\rm E(X) = np\\[/tex]

A bag contains 6 red markers, 5 blue markers, and 4 green markers.

A marker is randomly selected, its color is recorded, and it is returned to the bag.

This is repeated 1050 times.

n = 1050

Then the value of p will be

[tex]p=\dfrac{^6C_1}{^{15}C_1} = \dfrac{6}{15} = 0.4[/tex]

Then the expected value will be

[tex]\rm E(X) = np\\\\\rm E(X) = 1050 \times 0.4 \\\\\rm E(X) = 420[/tex]
