the mean mass of 6 boxes is 45kg. one of the boxes with a mass of 50kg is removed. calculate the new mean mass of the remaining boxes
Answer: 6 boxes. average 45 each.
Step-by-step explanation:
The mean of a dataset if the average of the dataset.
The new mean mass of the remaining boxes is 44 kg
From the question, we have:
[tex]\mathbf{\bar x = 45}[/tex] --- mean of 6 boxes
The mean of a dataset is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
So, we have:
[tex]\mathbf{45 = \frac{\sum x}{6}}[/tex]
Multiply by 6
[tex]\mathbf{45 \times 6= \sum x}[/tex]
[tex]\mathbf{\sum x = 270}[/tex]
One of the boxes is 50 kg.
So, the mass of the remaining boxes is:
[tex]\mathbf{Mass = 270 - 50}[/tex]
[tex]\mathbf{Mass = 220}[/tex]
The mean of the remaining boxes is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
[tex]\mathbf{\bar x = \frac{220}{5}}[/tex]
[tex]\mathbf{\bar x = 44}[/tex]
Hence, the new mean mass of the remaining boxes is 44 kg

Last year Jo paid £245 for her car insurance.
This year she has to pay £883 for her car insurance.
Work out the percentage increase in the cost of her car insurance
Answer:
The percentage increase in the cost of her car insurance is 260.4%
Step-by-step explanation:
First, we are going to find by how much the insurance increased:
We know that this year she pays £883 and the last year she paid £245, so
insurance increase = £883 - £245
insurance increase = £638
Now, we are going to find what percentage of the last year price is the insurance increase. So, to find the percentage increase in the cost of the car insurance, we need to divide the insurance increase by the last year price and multiply the result by 100%
percentage increase = (\frac{638}{245} )(
245
638
) (100%)
percentage increase = (2.604)(100%)
percentage increase = 260.4%
We can conclude that Jo's car insurance cost increased 260.4%
Maya has a smart phone data plan that costs $50 per month that includes 2 GB of dat, but will charge extra $15 per GB over the included amount. How much would Maya have to pay in a month where she used 3 GB over a limit? How much would maya have to pay in a month where she used over by x GB?
Answer:
a. $65
b. $(50 + 15x)
Step-by-step explanation:
A. From the question, we are told that the first 2 GB of data costs $50 while the subsequent extra GB cost $15 per GB
so for 3 GB, the normal $50 is charged for the first 2 GB while an extra $15 is charged for the extra 1 GB
so, the total amount charged for 3 GB will be $50 + $15 = $65
B. Amount to be paid in a month where x GB is used over the normal
Firstly, she will pay the $50 , then for the extra she will be paying $15 * x = $15x
So the amount to be paid will be;
$50 + $15x = $(50 + 15x)

Hope this helps girly!!
Answer:
[tex]\angle{C}=54[/tex]
Step-by-step explanation:
Let's first start by establishing that when it comes to a reflection, side lengths and angle measurements remain the same. With that being said, let's identify our angle measurements:
[tex]\angle{A=}\\\angle{B}= 67\\\angle{C}=\\\angle{A'}=59\\\angle{B'}=\\\angle{C'}=\\[/tex]
As mentioned earlier, angle measurements will remain the same, so we can go ahead and identify the values of [tex]\angle{A}[/tex] & [tex]\angle{B'}[/tex]
[tex]\angle{A=59}\\\angle{B}= 67\\\angle{C}=\\\angle{A'}=59\\\angle{B'}=67\\\angle{C'}=\\[/tex]
The sum of the angles in a triangle will always be equal to 180°.
Add the two identified angles of the original figure.
[tex]59+67=126[/tex]
Subtract the sum from 180:
[tex]180-126=54[/tex]
Therefore:
[tex]\angle{C}=54[/tex]
_
Check your work by adding the three identified angle measurements to see if they measure to 180°:
[tex]59+67+54[/tex]
[tex]=180[/tex]

What is 8 divided by 3526
Answer:
The answer is 4/1763 in fraction
In decimal, the answer is 0.001 rounded to thousandths.
Step-by-step explanation:
If you want to divide this, you will have to make this expression to a fraction
to 8/3526. Divide the highest numerator if the fraction can simplify. It looks like 3526 can only be simplified by being divided by 2. Divide 2 to each side of the fraction. You should get 2/1763 as a fraction.

4.5 times what equals 5
Answer:
REEEEEEEEEEEEEEEEEEEEE
Step-by-step explanation:
i thnk that the answer is .9333 !!
The 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.
To find the number that, when multiplied by 4.5, equals 5, we can set up an equation and solve for the unknown number.
Let's represent the unknown number as 'x':
4.5 * x = 5
To isolate 'x', we need to get rid of the coefficient 4.5. To do that, we'll divide both sides of the equation by 4.5:
x = 5 / 4.5
Now, perform the division:
x = 1.111...
The result is a repeating decimal, which means the number that satisfies the equation is 1.111... (with 1 repeating indefinitely).
To express the result more precisely, we can write it as a fraction:
x = 5 / 4.5 = 10 / 9
Therefore, 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.

In the polynomial shown in the graph below, are there any places that could be described as either a local minimum or local maximum? Neither? Both?
Answer:
Local Min and Local Max
Step-by-step explanation:
Since our end behavior of our graph is goes on to infinity and negative infinity, we know that we will not have an absolute min or max. However, we will have relative/local min and max.
The local min and max are mins and maxes relative to the surrounding points. We see that our local min would happen around x ≈ 0.75 and our local max will happen at x ≈ -1.9.
