In a housing project there are 180 households in which English is usually spoken, 80 in which Spanish is usually spoken, and 40 in which the language is other than English or Spanish. A researcher approaches a house at random to conduct an interview. What is the chance that the usual language in that household will NOT be English

Answers

Answer 1

Answer:

The chance that the usual language in that household will NOT be English = 0.4

Step-by-step explanation:

As given ,

Total households in which languages spoken is English = 180

Total households in which languages spoken is Spanish = 80

Total households in which languages spoken is other than English or Spanish  = 40

So,

Total households = 180 + 80 + 40 = 300

Now,

Household in which English language is not spoken = 80 + 40 = 120

So,

The chances that the usual language in that household will NOT be English = [tex]\frac{120}{300} = \frac{12}{30} = \frac{4}{10} = 0.4[/tex]

∴ we get

The chance that the usual language in that household will NOT be English = 0.4

Step-by-step explanation:

let 'x' = cost of bill for 30,000 gallons

a) i set up a proportion as follows:

$1.33/748g = x/30,000

i cross-multiplied and got $53.34

b) i set up a proportion as follows:

let 'y' = how many gallons $150 can buy

$1.33/748g = 150/y

i cross-multiplied and got 84,360.9 gallons

If a family has 8 children , in how many ways could the parents have 5 boys and 3 girls

Answers

That depends on what you mean by a "way" of having children. Some of the more obvious answers: One. Four boys and four girls, there's no other way of getting that many boys or that many girls. 40320. Usually each child has its own distinct DNA. The information in DNA can be converted into a number, and there are 8-factorial = 8! = 40320 orderings for eight numbers. 70. If each boy is considered to be the same until it is born and then named, so that the first four boys will always be named the same way and the same for the girls, then you can find the number of ways using binomial coefficients. The number of ways of arranging four equal boys and four equal girls into an order, is the same as the number of ways of choosing four numbers from 1 to 8 representing the position of the boys in that order. The number of ways of choosing a set of 4 numbers from 8 is called "8 choose 4" sometimes written 8C4 and is calculated as (8*7*6*5)/(4*3*2*1) (The numererator product in nCr stops when you have r numbers) (8*7*6*5)/(4*3*2*1) = 70

Answer:

As parents have 5b and 3 g

so if we add them it becomes 8

hence family has 8 children

Required

Ratio of odd numbers to total

First, list out the odd numbers

[tex]Odd = \{5,7,9,11\}[/tex]

The card has 4 odd numbers out of a total of 6.

So, the ratio is:

Amy drove her hoverboard 3 miles in 40 minutes. Jim hopped 2 miles in 20 minutes. Who traveled at a greater average speed? Define an appropriate unit of speed and provide mathematical justification for your answer

Answers

Answer:

Amy traveled at 4.5 mph, while Jim traveled at 6 mph. Therefore, Jim traveled at a greater average speed.

Step-by-step explanation:

Given that Amy drove her hoverboard 3 miles in 40 minutes, while Jim hopped 2 miles in 20 minutes, to determine who traveled at a greater average speed, the following calculation must be performed:

(3/40) x 60 = Amy's speed

0.075 x 60 = Amy's speed

4.5 = Amy's speed

So Amy traveled 4.5 miles per hour.

(2/20) x 60 = Jim's speed

0.1 x 60 = Jim's velocity

6 = Jim's speed

Instead, Jim traveled 6 miles per hour.

Therefore, Jim was the one who traveled at a greater average speed.

The mean is 8.4

Step-by-step explanation:

First you find the class centers.

3-6 = 4.5

7-10 = 8.5

11-14 = 12.5

15-18 = 16.5

The sum of all the scores = 4.5 * 7 + 8.5 * 10 + 12.5 * 6 + 16.5 + 2 = 210

The sum of the number of scores = 7 + 10 + 6 + 2 = 25

The mean = 210/25 = 42/5 = 8.4

Answers

Answer:

Step-by-step explanation:

We are given that

Day       Hours

Sunday    0

Monday   1.5

Tuesday    2.5

Wednesday  2.5

Thursday       3

Friday            0

Saturday       n

Mean number of hours of  study per day=1.5

Mean=[tex]\frac{sum\;of\;data\;}{total\;number\;of\;data\;points}[/tex]

Total number of days=7

Using the formula

[tex]1.5=\frac{0+1.5+2.5+2.5+3+0+n}{7}[/tex]

[tex]1.5\times 7=9.5+n[/tex]

simplify the expression 3(6/5x+4y+6)-2(9/5x+8y+3)​

Answers

Answer:

-20(y-3)/3

Step-by-step explanation:

The expression can be written simplified as 6x - 4y + 12.

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The expression is given as:

3(6/5x+4y+6)-2(9/5x+8y+3)​

To simplify the expression, we need to use the rules of algebra to combine like terms and perform the necessary operations in the correct order.

First, we can distribute the 3 and the -2 to the terms inside the parentheses:

3(6/5x+4y+6) - 2(9/5x+8y+3)

= 18/5x + 12y + 18 - 18/5x - 16y - 6

Next, we can combine like terms:

= 18/5x - 18/5x + 12y - 16y + 18 - 6

= 6/5x - 4y + 12

Finally, we can simplify the fraction by dividing the numerator and the denominator by their greatest common divisor, which is 1:

= (6/1) / (5/1)x - 4y + 12

= 6x - 4y + 12

Therefore, the simplified expression is 6x - 4y + 12.
