Answer:

there are 30 boys

Step-by-step explanation:

If there is 24 girls you divide that by 4 and you get six so that means you multiply with six and you get 30.

A ratio of 4:5 means that for every 4 girls, there are 5 boys.

24 girls / 4 girls = 6

5 * 6 = 30 boys

There are 30 boys if there are 24 girls

Answer:

I think they spent altogether $72

Step-by-step explanation:

Since each person had a ticket, five friends would have $25 worth of tickets. Since they watched 2 movies, you would do 25 times 2 and get 50. Since they all had one bag of popcorn for $2, they would have to pay $10 for the popcorn. And since they had to spend $12 for the pizza and the large bottle of soda, they would've spent $72 altogether for the movie trip and the pizza. Hope this helps! Have a great day!

Answer:

z = -1

Step-by-step explanation:

Simplifying

z + (z + -6) + -2 = -10

Reorder the terms:

z + (-6 + z) + -2 = -10

Remove parenthesis around (-6 + z)

z + -6 + z + -2 = -10

Reorder the terms:

-6 + -2 + z + z = -10

Combine like terms: -6 + -2 = -8

-8 + z + z = -10

Combine like terms: z + z = 2z

-8 + 2z = -10

Solving

-8 + 2z = -10

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 2z = -10 + 8

Combine like terms: -8 + 8 = 0

0 + 2z = -10 + 8

2z = -10 + 8

Combine like terms: -10 + 8 = -2

2z = -2

Divide each side by '2'.

z = -1

Simplifying

z = -1

Answer:

Answer:

A. 12/25

B. 96 pieces

Step-by-step explanation:

A. For this, Ida got 12/25 lemon taffies, therefore the probability is the same.

B. The ratio of lemon to other taffies is 12/25. This means that for every 25 pieces of taffy, 12 of them are lemmon. If you multiply the numerator and denominator by 8, you get 96/200, which says that out of 200 pieces, 96 should be candy.

Answer:

P(not getting a ticket for 2 days) = 0.49

Step-by-step explanation:

We are told that the probability of getting a ticket on any given day is 0.3.

Thus;

P(getting a ticket a day) = 0.3

This means that;

P(not getting a ticket a day) = 1 - 0.3 = 0.7

Now, 0.7 is probability of not getting a ticket for 1 day. Since each day's outcome is independent of the previous day's outcome, it means that for n days, probability of not getting a ticket for n days will be;

P(not getting a ticket for n days) = 0.7ⁿ

For 2 days, its = 0.7² = 0.49

Thus;

P(not getting a ticket for 2 days) = 0.49

Answer:

1 1/2 mile

Step-by-step explanation:

In 1 hour they pave 6 times more what they paved in 1/6 of an hour.

6 * 1/4 mile = 6/4 mile = 3/2 mile = 1 1/2 mile

Answer:

0.0128

Step-by-step explanation:

(Use technology and enter your answer rounded to four decimal places.)

We apply the z score formula to this question

z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

We are given: N(2750,560)

x = 1500 grams, μ = 2750 grams, σ = 560 grams

= z = 1500 - 2750/560

z = -2.23214

Determining the Probabilty value from Z-Table:

P(x < 1500) = P(z = -2.23214)

= 0.012803

Approximately to four decimal places = 0.0128

The probability that a randomly chosen late-preterm baby would have a very low birth weight, less than 1500 grams is 0.0128.

Answer: d. 658,350

Step-by-step explanation: A total of 3,300,000 of tax returns are filed.

When filed electronically, 0.05% of all the returns contain errors, which means:

3,300,000 * [tex]\frac{0.05}{100}[/tex] = 1650

When filed manually, 20% contain error:

3,300,000 * 0.2 = 660000

The difference of the number of tax returns that contain error between manually and electronically filed is

660,000 - 1,650 = 658,350

There will be 658,350 tax returns filed manually more than electronically.

The number of manually filed returns containing errors will there be than electronically filed returns containing errors is: d. 658,350.

Using this formula

Number of manually filed returns=(Tax returns filed manually contain errors×Tax return)- (Tax returns filed electronically contain errors× Tax return)

Let plug in the formula

Number of manually filed returns=(20%×3.3 million)-(0.05%×3.3 million)

Number of manually filed returns=660,000-1650

Number of manually filed returns=658,350

Inconclusion the number of manually filed returns containing errors will there be than electronically filed returns containing errors is: d. 658,350.

Answer:

B is a prime number

Step-by-step explanation:

The definition of a prime number is if the number is divisible by itself and one. 14 is divisible by 7, 18 is divisible by 6, and 33 is divisible by 11 and 3......  Only two among all these numbers has 2 factors: It is divisible by one and itself, 2.

Therefore the answer is 2!

General Formulas and Concepts:

Area of a Rectangle: Length × Width

To expand, use FOIL - First, Outside, Inside, Last

Step-by-step explanation:

Step 1: Define variables

l = 3x - 5

w = 2x

Step 2: Find area

Answer: A=6x^2-10x ✅

Step-by-step explanation:

Hii, do you need to find the area of the rectangle? Let me help you out! (:

Luckily, there's a formula to find this! (:

To find the area of a rectangle, multiply its length times its width. This is shown below.

[tex]\LARGE\boldsymbol{A=L W}[/tex]

Here, "A" denotes the area

"L" denotes the length

"W" denotes the width

NB : "L" and "W" are interchangeable

Next, it's just a matter of sticking in the known values...

[tex]\twoheadrightarrow\sf A=2x(3x-5)[/tex]

===> it's perfectly legal to stick in the values the other way around, because they are interchangeable

Alright, the next step is to multiply the values...

[tex]\twoheadrightarrow\sf A=(2x\cdot3x)-(2x\cdot(-5)[/tex]

Then we need to simplify...

[tex]\twoheadrightarrow\sf A=6x^2-10x[/tex]

Voila! There's the area of this rectangle! (:

Hope I helped! Best wishes.

Let x be the sales last year .

Then :-

[tex] \frac{28}{100} \: of \: x = \: \: 70560[/tex]

[tex] \frac{28}{100} x = 70560[/tex]

[tex]x = \frac{70560 \times 100}{28} [/tex]

[tex]x = \frac{7056000}{28} [/tex]
