Answer:
[tex]Unit\ Charge = -6\ units[/tex]
Step-by-step explanation:
Question is incomplete; However, the missing part of the question will most likely be to calculate the charges on each particle.
If that is the case;
[tex]Tota\l Charges = -42\ units[/tex]
We'll get the unit charge when we divide by 7.
This is so because, they all have the same charge.
[tex]Unit\ Charge = -42\ units/7[/tex]
[tex]Unit\ Charge = -6\ units[/tex]
Hence;
the unit charge is -6 units
Answer:
the unit charge is -6 units

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!!

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

Eight slips have a $3$ on them and the other two have a $9$ on them. How many $9$'s do I have to add before the expected value is at least $8$? 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 .
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
Thus,
The probability of rolling a 4 and an even number is 2/3.

What is 6.25 divided by 132
Answer:
0.04734848484
Step-by-step explanation:
The 6.25 divided by 132 equals 0.235 (rounded to three decimal places).
To calculate 6.25 divided by 132, perform the following steps:
Step 1: Divide the whole number part.
Divide 6 by 132, which equals 0 with a remainder of 6.
Step 2: Convert the remainder to a fraction.
The remainder 6 becomes 6/132.
Step 3: Divide the fractional part.
Divide 25 by 132, which gives the fraction 25/132.
Step 4: Add the results from Step 2 and Step 3.
Combine the fractions obtained in Step 2 and Step 3: 6/132 + 25/132 = 31/132.
The final result is 0 31/132, which can be simplified to 0 7/44 or written as a decimal as approximately 0.235. Therefore, 6.25 divided by 132 equals 0.235 (rounded to three decimal places).

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.

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.

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
