I WILL GIVE BRAINLIEST TO WHOEVER ANSWES ALL OF THEM CORRECT
Answer:
Step-by-step explanation:
1 ) No of total slips after addition = 11
8 slip with 3 on it
3 slips with 9 on it
expectation value = probability of 3 x 3 + probability of 9 x 9
= (8 / 11) x 3 + (3 / 11) x 9
24 / 11 + 27 / 11 = 4.636
2 )
No of total slips after addition = 12
8 slip with 3 on it
4 slips with 9 on it
expectation value = probability of 3 x 3 + probability of 9 x 9
= (8 / 12) x 3 + (4 / 12) x 9
2 + 3 = 5
3 )
Let n be the required number
No of total slips after addition = 10+n
8 slip with 3 on it
2 + n slips with 9 on it
expectation value = probability of 3 x 3 + probability of 9 x 9
= (8 / 10+n ) x 3 + (2+n / 10+n ) x 9 = 6
24 + 18 + 9n / 10 + n = 6
42 + 9n = 60 + 6n
3 n = 18
n = 6
4 )
Let n be the required number
No of total slips after addition = 10+n
8 slip with 3 on it
2 + n slips with 9 on it
expectation value = probability of 3 x 3 + probability of 9 x 9
= (8 / 10+n ) x 3 + (2+n / 10+n ) x 9 = 8
24 + 18 + 9n / 10 + n = 8
42 + 9n = 80 + 8n
n =
n = 38
Minimum of 38 has to be added .
According to the 2010 census, the state of Oregon has a population of 40 people per square mile. If a county in Oregon measured 75 miles by 30 miles, then what is the expected population of the county?
Answer:
90000
Step-by-step explanation:
To get the total area multiply 75 by 30 then to get the number of people multiply the product by 40. 75*30*40=90000
What is the ratio of the afternoon to morning temperatures shown in the table? Temperatures Morning Afternoon 15 degrees. 30 degrees. 20 degrees. 40 degrees. 26 degrees. 52 degrees. 1 to 13 1 to 2 2 to 1 13 to 1
Given:
Morning Temperature = 15 degrees, Afternoon Temperature = 30 degrees
Morning Temperature = 20 degrees, Afternoon Temperature = 40 degrees
Morning Temperature = 26 degrees, Afternoon Temperature = 52 degrees
To find:
The ratio of the afternoon to morning.
Solution:
Taking any one pair of morning and afternoon temperature, we can find the ratio.
Morning Temperature = 15 degrees
Afternoon Temperature = 30 degrees

Answer:
$459.65
Step-by-step explanation:
The total number of cartons you filled was ...
210 +175 +224 +160 +216 +90 = 1075
so your pay for filling those is ...
$0.41 × 1075 = $440.75
You get an additional amount of pay for the cartons filled on Saturday:
$0.21 × 90 = $18.90
So your pay for the week is ...
$440.75 +18.90 = $459.65

What is the distance between the two points ?
A)6.5
B)6.3
C)16
D)6.7
Answer:
The answer is option BStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
( -2 , 1) and ( 4,3)
The distance is
[tex]d = \sqrt{( { - 2 - 4})^{2} + ({1 - 3})^{2} } \\ = \sqrt{ ({ - 6})^{2} + ({ - 2})^{2} } \\ = \sqrt{36 + 4} \\ = \sqrt{40} \\ = 2 \sqrt{10} \\ = \:6.324555[/tex]
We have the final answer as
6.3Hope this helps you
Step-by-step explanation:
Hey there!!!
Given, the points are (4,3) and (-2,1).
Then,
x1=4 x2=-2
y1=3 y2=1
Now, Using distance formula,
[tex](distance ) = \sqrt{ {(x2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]
Put all values.
[tex](distance ) = \sqrt{ {( - 2 - 4)}^{2} + {(1 - 3)}^{2} } [/tex]
Simplify them.
[tex](distance ) = \sqrt{( { - 6)}^{2} + ( { - 2)}^{2} } [/tex]
[tex](distance ) = \sqrt{36 + 4} [/tex]
[tex](distance ) = \sqrt{40} [/tex]
(distance )= 6.3245 units.
Therefore, the distance between the points(4,3) and (-2,1) is 6.32units.
So, your answer is option B.

The perimeter of a rectangle is 34 units. Its width is 6.56, point, 5 units.
Answer: equation for length 34- (6.5 times 2) that whole thing divided by 2
Step-by-step explanation:
You know the width and a rectangle has 2 PAIRS of equal sides so if you know the width you just have to multiply that by 2 [ to account 4 the other side with the same length] and subtract that from the perimeter! Then you divide that answer by 2 to get what one side's length is!

Which term does not belong in this series?
64, 16, 4, 1, 1/2, 1/16
A) 1
B) 4
C) 16
D) 1/2
Answer:
D) 1/2
Step-by-step explanation:
The pattern shown in the sequence is that every number is divided by 4 (left to right) or multiplied by 4 (right to left). How did I get 4? I multiplied 64 by 16 (64/16) !
64 / 4 = 16
16 / 4 = 4
4 / 4 = 1
1 / 4 = 1/4 or 0.25 >> not 1/2 or 0.50!!

twice a number is equal to fourteen
The number is 7, as twice that number equals fourteen.
Let's represent the number as "x".
According to the given information, twice the number is equal to fourteen. Mathematically, we can write this as:
2x = 14
To find the value of the number, we need to solve this equation for "x". Dividing both sides of the equation by 2, we get:
x = 14/2
Simplifying the right side of the equation, we have:
x = 7
Therefore, the number is 7.

Suppose we roll a die once. What is the probability that we roll a 4 or an even number?
Answer:
You have a 1/2 or 50% chance of rolling a 4 or an even number
Step-by-step explanation:
They're three even numbers on a die 2,4,6 and that's half of the total option.
The probability of rolling a 4 and an even number is 2/3.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Sample space for rolling dice.
= {1, 2, 3, 4, 5, 6}
There are 6 possible outcomes.
There are three even numbers.
The probability of rolling a 4 or an even number.
= 1/6 + 3/6
= 1/6 + 1/2
= (1 + 3)/6
= 4/6
= 2/3

Estimate the following sum by first rounding each decimal to the nearest hundred.
428.1 + 186.5 + 210.62
Enter your answer in the box.
The sum of the following figures = 800
To round up each decimal to the nearest hundred,
428.1 = 400
186.5 = 200
210.62 = 200
Note:
If the figure closest to the nearest hundred figure is greater than or equal to five then 1 should be added to the hundred figure. But if less than 5, the hundred figure remains the same.Therefore, the sum of 400 + 200 + 200 = 800
