Answer:

1.5

Step-by-step explanation:

Answer:

0.7

Step-by-step explanation:

30 cannot be multiplied to give a power of 10, so to find the decimal you have to divide: 2/3 = 2/3 + 2 ÷ 3

2 divided by 3 is 0.6666666... It is a recurring decimal.

However it is not practical to use recurring decimals in calculations, so the decimal is usually rounded off to 2 or 3 decimal places depending on the accuracy required for the answer.

Answer: The mean increases by 2.1

Step-by-step explanation:

According to the given description (dots are denoting the frequency for each value), the given data is :-

50 , 72, 72 , 74, 76 , 78 , 79 , 79 , 79 80, 81, 82, 82, 82

[Note - We take 79 as the value between 78 and 80, 81 as between 80 and 82 ]

Mean = [tex]\overline{x}_1=\dfrac{\text{Sum of observations}}{\text{No. of observations}}[/tex]                   (1)

[tex]=\dfrac{1066}{14}=76.1428571429\approx76.1[/tex]

First Quartile: [tex]Q_1=[/tex] Median of the lower half ( 50 , 72, 72 , 74, 76 , 78 , 79 )

= 74

Third Quartile: [tex]Q_3=[/tex] Median of the upper half (  79 , 79 80, 81, 82, 82, 82 )

= 81

Interquartile range (IQR)=[tex]Q_3-Q_1=81-74=7[/tex]

According to the IQR rule,

Upper limit = [tex]1.5\times IQR+Q_3=1.5\times7+81=91.5[/tex]

Lower limit = [tex]Q_1-1.5\times IQR=74-1.5\times7=63.5[/tex]

Since 50 < 63.2 , so 50 is outlier .

When 50 is removed from the data , the new data will be 72, 72 , 74, 76 , 78 , 79 , 79 , 79 80, 81, 82, 82, 82

Mean = [tex]\overline{x}_2=\dfrac{\text{Sum of observations}}{\text{No. of observations}}[/tex]

[tex]=\dfrac{1016}{13}=78.1538461538\approx78.2[/tex]      (2)

Change in mean from (1) and (2)

[tex]\overline{x}_2-\overline{x}_1\\\\=78.2-76.1=2.1[/tex]

Hence,  the mean increases by 2.1.

Answer:

Question1: 58660

Question 3: 7244

Step-by-step explanation:

Question 1: My 5 is worth 50,000 means the number will start with 5 and will be between 50,000 and 60,000, thus will have 5 digits in total

My 8 is worth 8,000 means the next number is 8

One of my 6s is worth 60 means there is more than one 6. One 6 is worth 60 and the other is 10times as much so 600. The other digit is a 0. So those 3 together are 660.

The entire number is 58660

Question 3: The number has 4 digits:

My 7 is worth 7000 so the number will be between 7,000 and 8,000.

My 2 is worth 200 so.

One of my 4s is worth 40. So this means there is another 4.

The other number is 1/10 of 40, which is 4.

The total is 7244

Answer:

x < 3

Step-by-step explanation:

Apply distributive property on the left of the inequality to get rid of the parenthesis:

8+4x > 5x+5

subtract 4x from both sides to group all terms with x on the right:

8 > 5x-4x+5

8 > x +5

Now subtract 5 from both sides to collect all numerical terms on the left:

8 - 5 > x

3 > x

Therefore the solution to the inequality are of those real numbers strictly smaller than 3.

The inequality can be written as x < 3 or also as we had it initially: 3 > x

Notice that the opening of the angle symbol is always facing the number 3 , meaning that 3 is the larger of the two numerical objects that are compared.

Answer:

Kyle gave 2/7th  of his money to his wife and spent 3/5 of the remainder. If he had $300 left, the money had by Kyle at first is $1050

Solution:

Step 1:

Consider “x” as the money which Kyle had initially.  

From question, Kyle gave 2/7th of his money to his wife. So the remaining money left with Kyle is given as,

[tex]= 1 - \frac{2}{7}[/tex]

[tex]= \frac{7 - 2}{7} = \frac{5}{7}[/tex] ----- eqn 1

Now the remaining money left with Kyle is 5/7th.Given that Kyle spent 3/5 of the remaining money.  

Now the remaining money left with Kyle is given as  

[tex] = 1 - \frac{3}{5} = \frac{5 - 3}{5} = \frac{2}{5}[/tex]

Now kyle is left with $300, which is 2/5th of the initial money x .

We get equation as  

[tex]\frac{2}{5} x=300[/tex]

2x = 1500

x = 750

Now Kyle is left with 750$ which is 5/7th of the initial amount x.( by using eqn 1)

We get equation as

[tex]\frac{5}{7} x = 750[/tex]

5x = 5250

x = 1050

So the amount had by Kyle at first is $1050

Final answer:

Working backward from the $300 Kyle had after spending and giving some away, we find that the original amount of money was $1050, which is determined by reversing the operations he performed on his money.

Explanation:

To solve how much money Kyle had at first, we need to work backwards from the amount he had left ($300) after he spent some and gave some to his wife. First, we determine how much was left before he spent the 3/5 of the remainder.

Let's denote Kyle's initial amount of money as x. The equation representing what Kyle did with his money is

x - (2/7)x = Remaining Amount After Giving to Wife

Kyle then spends 3/5 of this remaining amount, and is left with $300, so we can represent this as:

(1 - 3/5)(Remaining Amount After Giving to Wife) = $300

Substituting the first equation into the second we get:

(1 - 3/5)(x - (2/7)x) = $300

Simplifying, we find that (2/5)(5/7)x = $300.

This simplifies down to:

(2/5)(5/7)x = (10/35)x = $300

Finally, solving for x, we multiply both sides by the reciprocal of (10/35),

x = $300 × (35/10)

x = $300 × 3.5

x = $1050

So, Kyle originally had $1050.

There are 11 halves in 5 and 1/2.

A fraction is a number that is represented as a quotient where the numerator is divided by the denominator.

Two equal parts of one whole thing. In fraction form, half can be written as 1/2.

We have to find the number of halves in 5 and 1/2. We know that there are 2 halves of one whole thing. For 5 as a whole number, the number of halves would be,

5 × 2 = 10. Then, there are 10 halves in 5. Notice that there is one more 1/2 in 5 and 1/2. We can conclude that there are 10 + 1 = 11 halves in 5 and 1/2.

Therefore, there are 11 halves in 5 and 1/2.

To solve the given statement '12 less than m is no less than 132', we set up the inequality m - 12 ≥ 132. Adding 12 to both sides, we find that m ≥ 144.

Given the statement '12 less than m is no less than 132', we can set up an inequality to represent this relationship: m - 12 ≥ 132. To solve for m, we can add 12 to both sides of the inequality: m ≥ 132 + 12. Simplifying, we find that m ≥ 144. So, any value of m that is greater than or equal to 144 will satisfy the given statement.

To solve the equation a = 2x + 6xz for x, isolate x on one side of the equation by following the steps: subtract 6xz from both sides, factor out x, and divide both sides by (2 + 6z).

To solve the equation a = 2x + 6xz for x, we need to isolate x on one side of the equation. Here are the steps:

Start with the equation: a = 2x + 6xz

Subtract 6xz from both sides: a - 6xz = 2x

Factor out x on the right side: a - 6xz = x(2 + 6z)

Divide both sides by (2 + 6z): (a - 6xz) / (2 + 6z) = x

Therefore, the solution for x is x = (a - 6xz) / (2 + 6z).

Have a nice day!!!!!! :-)

KA

To divide 64.8 by 7 using long division, calculate how many times 7 can be subtracted from each part of the number 64.8 in sequence. This results in the final answer of 9.25.

To find 64.8 divided by 7 using long division, first write down 64.8 with a division bar over it and 7 on the left side of the bar. You would write:

7 | 64.8

Next, ask: How many times does 7 go into 64? This is 9 times since 7 times 9 is 63. Record the 9 above the line and record the product (63) below 64. Subtract 63 from 64 to get 1.

Bring down the 8 (from 64.8) to the right of the 1. Now you have 18. Ask how many times does 7 go into 18? This is 2 times. So you add the digit 2 next to 9 on top of the bar. 7 times 2 is 14.

Subtract 14 from 18 to get 4. As the decimal point should be straight up from where it is in the 64.8, record a decimal point.

Now, since there's no more numbers to bring down, you can add a 0 to 40. 7 goes into 40, 5 times. Therefore, we add 5 next to the 2 after the decimal point. So, 64.8 divided by 7 is 9.25.

Answer:

35 subscribers

Step-by-step explanation:

Divide $43.75 by $1.25.

$43.75/$1.25 = 35

For each subscriber he gets, his service goes down by $1.25.

Since 35 * $1.25 = $43.75, for 35 new subscribers, his service will go down by $43.75.

He pays $43.75, so if the service goes down by $43.75, he will pay nothing since $43.75 - $43.75 = 0.

Answer: 35 subscribers

Follow below steps:

To determine how many users Mike must recruit for him to stream movies for free, we need to set up a simple algebraic equation. Mike's service costs $43.75 per month, and for each new subscriber he recruits, his rate is reduced by $1.25. Let's say the number of users Mike needs to recruit is represented by x.

The cost reduction for recruiting x users would be $1.25x. To get a free service, the total cost reduction must equal the monthly service cost of $43.75. Thus, the equation is $1.25x = $43.75.

To solve for x, we divide both sides by $1.25:

x = $43.75 / $1.25

x = 35

Therefore, Mike must recruit 35 new subscribers to stream movies for free.
