Answer: 8

Step-by-step explanation:

Given

lottery win is inversely proportional to the number of tickets matching the correct number.

Suppose lottery amount is given by A and no. of tickets by n then

[tex]\Rightarrow A\propto \frac{1}{n}\\\Rightarrow A\cdot n=\text{constant}[/tex]

Initially A=£1400, n=20

then A=£3500, n=?

Product in both the case is same

[tex]\therefore \quad 1400\times 20=3500\timesn\\\Rightarrow n=8[/tex]

There are 8 tickets that matched the correct numbers

Answer:

The slope is 1/3

Step-by-step explanation:

Equation for slope is rise over run or y2-y1/x2-x1

-5,1 -2,2 these are the 2 points, so it could be 2-1/-2--5 which is equal to 1/3.

Answer:

6

Step-by-step explanation:

since it's a right triangle you can use the Pythagorean Theorem

2.7² + b² = 6.5²

7.29 + b² = 42.25

b² = 34.96

b = [tex]\sqrt{34.96}[/tex] which equals 6 when rounded to the nearest tenth

Answer:

5

Step-by-step explanation:

The number of cubes that should be on each side of the frame should be considered as the 5.

Since Sally used 8 cubes to make this square frame that has 3 cubes on each side.

So here the no of the cube be like

= 8  - 3

= 5

hence, The number of cubes that should be on each side of the frame should be considered as the 5.

The mean age of 5 people in a room is 26 years. A person enters the room. the mean age is now 33 so the age of the person 68 who entered the room.

In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all of the values are organized in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.

So According to the question, the Mean of  5 people in a room =26

When a person enters the room mean age becomes = 33

The sum of their age is = 5*6 =130

when other persons enter the room means the total person becomes =6

and the sum of their age after another person enters the room= [tex]x+130[/tex]

where x is the age of the other person entering the room.

so, mean = 33= (130+x)/6

 then, 130+x=6*33

   And,130+x=198

so,x=198-130  =68

Answer:

Distributive Property

Step-by-step explanation:

We have

5(3x - 6/7)

Distributive Property would work because 5 has to be mutliplied by 3x and -6/7 to rid the parenthesis and also give a final answer for the equation. Any others will lead to a wrong answer.

Answer:

11.14

Step-by-step explanation:

Mean = sum of numbers / total numbers

the mean of the 7 numbers = sum of the numbers / 7

sum of numbers for the 3 numbers = 10 x 3 = 30

Sum of numbers for the other 4 numbers = 12 x 4 = 48

Sum of the 7 numbers = 48 + 30 = 78

Mean of the 7 numbers = 78 / 7 =  11.14

Step-by-step explanation:

Answer:

The person's angular momentum will be double

Step-by-step explanation:

Let

Speed of person=v

Mass of person=m

Radius=r

Speed of person=2v

We have to find the person's angular momentum when the speed of person is double and all else remains same.

We know that

Angular moment ,L=mvr

Using the formula

Angular momentum of person when speed 2v

L'=m(2v)r

[tex]\frac{L'}{L}=\frac{m(2v)r}{mvr}=2[/tex]

[tex]L'=2L[/tex]

Hence, the angular moment of person will be double when the speed of person is double.

To make it into percentage we need to always multiply it by 100

376/400 x 100

=94%

Thus 94% of the bulbs are non defective
