Explanation:

total students: 100%

----------------

number of girls:

Answer:

27

Step-by-step explanation:

a+b=7; a-b=3

Add the two equations together

a+b=7

a-b=3

----------------

2a + 0b = 10

2a = 10

Divide by 2

2a/2 = 10/2

a = 5

a+b = 7

5+b = 7

b = 7-5

b = 2

3^a / 3^b = 3^(a-b) = 3^(5-2) = 3^3 = 27

Answer:

It took 4/5 of an hour or 48 minutes

Step-by-step explanation:

Answer:

389

Step-by-step explanation:

20 - 11 = 9

29 - 20 = 9

This is a geometric sequence with a common difference of 9.

a_1 = 11

a_2 = 11 + 9

a_3 = 11 + 2 × 9

...

a_n = 11 + (n - 1) × 9

a_43 = 11 + (43 - 1) × 9

a_43 = 11 + 42 × 9

a_43 = 389

Hence, the [tex]43[/tex]rd term is [tex]389[/tex].

What is the sequence?

A  sequence is a list of objects, typically numbers, in which order matters, repetition is allowed, and the same elements can appear multiple times at different positions in the sequence.

Here given sequence is [tex]11, 20, 29, ...[/tex]

Here,

[tex]a=11\\\\d=a_2-a_1\\d=20-11\\d=9[/tex]

The general formula is

[tex]a_n=a+(n-1)d[/tex]

where,

[tex]a_n[/tex] is the [tex]n[/tex]th term

[tex]a[/tex] is the first term

[tex]n[/tex] is the number of terms

[tex]d[/tex] is the common difference

Substituting the values in the general formula

[tex]a_n=a+(n-1)d\\\\a_{43}=11+(43-1)9\\\\a_{43}=11+(42)9\\\\a_{43}=11+378\\\\a_{43}=389[/tex]

Hence, the [tex]43[/tex]rd term is [tex]389[/tex].

Step-by-step explanation:

The absolute value of any equation can never be negative.

|4x - 2| = -6 has a negative value -6.

The |4x - 2| = -6 has no solution for x because |x| can not be negative.

Answer:

6. $62.74 7.$331

Step-by-step explanation:

6. The original cost= $119.5

After 30% of discount = (70/100)× 119.5

= $83.65

After 25% discount = (75/100)× 83.65

= $62.74

7. Original cost= 679

Price after 35% discount = (65/100)×679=$441.35

Price after 25% discount = (75/100)× 441.35

=$331

So the final price will be = $331

Answer:

13.4 :)

Step-by-step explanation:

Pythagorean theorem: a^2 + b^2 = c^2

Now lets solve!!

12^2 + b^2 = 18^2

144 + b^2 = 324

Now we subtract!!

324 - 144 = b^2

180 = b^2

Now we need to find the square root!!

[tex]\sqrt{180}[/tex] = 13.4

Step-by-step explanation:

im a bit confused with the anwser choices, so just pick which ever one contains states 0.444 as it's answer choice.

hope this helps :)

Answer:

0.444

Step-by-step explanation:

1.) A rational number in the form of a fraction can be represented as a decimal by dividing the numerator by the denominator.

2.) Now let's divide 111.000000... by 250. Find enough decimal digits in the numerator so we can see whether the decimal terminates or starts to repeat. [tex]111/250 = .444[/tex]. Since the remainder is 000, this is a terminating decimal.

3.) The terminating decimal is [tex]\frac{111}{250} = 0.444.[/tex]

Answer:

3(x + 8) = 6

Step-by-step explanation:

let the number be x then the sum of x and 8 is x + 8 and multiplied by 3 is

3(x + 8) = 6 ( divide both sides by 3 )

x + 8 = 2 ( subtract 8 from both sides )

x = - 6

the number x is - 6

Using a discrete probability distribution, it is found that there is a 0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

Researching the problem on the internet, it is found that the distribution for the number of customers in line at the store is given by:

Hence, since each customer takes 3 minutes to check out, the probability that it will take more than 9 minutes for all the customers currently in line to check out is the probability that there are more than 3 customers, hence:

P(X > 3) = P(X = 4) + P(X = 5) = 0.10 + 0.05 = 0.15.

0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.
