The new volume after the edges of the box are increased by 1 unit = 266,491 units^3
Calculation of volume of rectangular boxThe volume of a rectangle= l×w×h
The surface area of the box = (side)^2
The sum of the edges of the box = 216 units
If area of the box x^² = 2002
X = √2002
X = 44.7units
But the sum of the edges = 216 units
44.7 + 44.7 + y = 216
make y the subject of formula,
y = 216 - 89.4
y= 126.6 units
Therefore the length, width and height of the rectangular box = 44.7, 44.7 and 126.6 units respectively.
When additional 1 unit is added to each edge it becomes,
44.7 +1 =45.7,
44.7 + 1 = 45.7and
126.6 + 1 = 127.6 units.
Therefore the new volume = 45.7×45.7 × 127.6 = 266,491 units^3.

What are statistics?Statistics is a mathematical tool defined as the study of collecting data, analysis, understanding, representation, and organization. Statistics is described as the procedure of collecting data, classifying it, displaying that in a way that makes it easy to understand, and analyzing it even further.
It is given that:
A fast-food chain claims one small order of its tater tots weighs 90 grams.
She weighs the next 14 random orders of tater tots before she eats them.
The sample mean X = 89.3 grams
The standard deviation SD = 3.71 grams
Z = (u - X)/sd
Z = (90 - 89.3)/3.71
Z = 0.18

Use the method of elimination to solve the pair of simultaneous equation 3a=2b+1,3b=5a-3
Answer:
a = 3
b = 4
Step-by-step explanation:
Simultaneous equation
3a = 2b + 1
3a - 2b = 1 ------------------(I)
3b = 5a - 3
-5a + 3b = -3 --------------(II)
Multiply equation (I) by 3 & equation (II) by 2 and then add. So, now 'b' will be eliminated and we can find the value of 'a'.
(I)*3 9a - 6b = 3
(II)*2 -10a + 6b = -6 {Now add}
-a = -3
a = -3/(-1)
[tex]\sf \boxed{a = 3}[/tex]
Plugin a = 3 in equation (I)
3*3 - 2b = 1
9 - 2b = 1
-2b = 1 - 9 {Subtracting 9 from both sides}
-2b = - 8
b = (-8)/(-2) {Dividing both sides by (-2_}
[tex]\sf \boxed{b = 4}[/tex]
Answer:
(a, b) = (3, 4)
Step-by-step explanation:
In order to eliminate one of the variables in this system of equations, both equations need to be multiplied by different numbers before they are added or subtracted. We can eliminate the 'b' variable by subtracting 3 times the first equation from 2 times the second. (Putting the 'b' terms on the same side of the equal sign makes this easier.)
__
2(3b) -3(2b +1) = 2(5a -3) -3(3a)
6b -6b -3 = 10a -6 -9a
3 = a . . . . . . . add 6 and collect terms
3b = 5(3) -3 . . . . use the second equation to find b from a
b = 4 . . . . . . . divide by 3
The solution is (a, b) = (3, 4).
_____
The multiplier used in each case is the coefficient of the variable in the other equation. The two equations have 'b' coefficients of 2 and 3, so we multiplied the equations by 3 and 2 before subtracting. That makes the 6b terms cancel, leaving only terms with the 'a' variable.
By swapping sides of the equation the way we did, the 'a' terms end up on the same side of the equal sign, which is where we want them. Likewise, the 'b' terms end up on the same side of the equal sign, so their cancellation is easier to see.

Find the area of the shape below:
NOTE: The figure is NOT drawn to scale
Answer:
Find the rectangle's area on the left hand side, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
Plug in what you know:-
A = l x w
A = 15 x 5
A = 75 square units is the area of the left rectangle.
Now let's find the rectangle's area on the right hand side, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
A = l x w
A = 15 x 4
A = 60 square units is the area of the right rectangle.
Now find the middle small horizontal rectangle's area, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
But, let's figure out the length first.
We know that from the left rectangle, the two side lengths beside the unknown length of the middle rectangle area 5 and 7.
The unknown length plus those two lengths (5&7) will have to equal 15 since that is the total length, so;
15 - (5 + 7) = x
15 - 12 = x
3 = x, so the unknown length of the middle rectangle is 3.
Plug in what you know into the formula:
A = l x w
A = 3 x 7
A = 21 square units is the area of the middle rectangle.
Now add up all the areas together:
75 + 60 + 21
= 156 square units is the area of the shape.

To find the equation of the tangent to the given function, you must differentiate the function with respect to 'x'. The derivative (y prime) will give the tangent line at any point along the function. After we find the tangent equation, we let x equal zero which will alow us to find the slope at that point.
Begin by bringing the entire denominator to the top. If not, you'll have to do the quotient rule which is very annoying 99% of the time. You will get:
[tex]y=5(e^{2x} +3)^{-1}[/tex]
With this now, you can use the chain rule twice. Begin by differentiating:
[tex]\frac{dy}{dx} =5\frac{d}{dx} [e^{2x} +3)^{-1}][/tex]
Use the chain rule:
[tex]\frac{dy}{dx} =-5(e^{2x} +3)^{-2}\frac{d}{dx} [e^{2x} +3][/tex]
Use the chain rule again:
[tex]\frac{dy}{dx} =-5(e^{2x} +3)^{-2}[2e^{2x} ][/tex]
Simplify:
[tex]y'=-\frac{10e^{2x} }{(e^{2x}+3)^{2}}[/tex]
Let x = 0 to get:
[tex]y'=-\frac{10}{4^{2}} =-10/16=-5/8=-0.625[/tex]

Which expression is equivalent to 20 - 35x ? *
Answer:
5[4 - 7x]
Step-by-step explanation:
Given expression:
20 - 35x
To factorize the expression, we need to determine the GCF of the terms.
⇒ 20 - 1, 2, 4, 5, 10, 20⇒ 35x - 1, 5, 7, x, 35Since "5" is the largest factor in both terms, the GCF is 5.
Factorize the expression using the GCF:
⇒ 20 - 35x⇒ 5[(20 ÷ 5) - (35x ÷ 5)]⇒ 5[(4) - (7x)]⇒ 5[4 - 7x]Thus, 5[4 - 7x] is equivalent to 20 - 35x.
To make lemonade, Carlos used 5 times more water than lemon juice. He used 3 pints of lemon juice. After making the lemonade, he poured it equally into 4 jugs. How many cups of lemonade are in each jug?
Answer:
11 Cups
Step-by-step explanation:
Carlos used 3 pints of lemon juice and 5 times more water than lemon juice. So, he uses 3 x 5 = 15 pints of water for the lemonade. The amount of lemonade is 15 + 3 = 18 pints. Now he pours it equally into 4 jugs which makes it 18 ÷ 4 = 4.5 pints in each jug. Now 1 pint fills 2.4 cups which means 4.5 pints will fill 4.5 x 2.4 = 10.8 cups which will apprroximately be 11 cups.
Find the mean and the median of this data set: 8, 7, 6, 3, 47, 7, 4, 2.
Answer:
Mean: 10.5
Median: 6.5
Step-by-step explanation:
To find mean, find the sum of all of the numbers, then divide the sum by how many numbers there are in the data set.
8 + 7 + 6 + 3 + 47 + 7 + 4 + 2 = 84
84 ÷ 8 = 10.5
To find the median, list the numbers in order from least to greatest, then take one number off from each end of the data set until you get to the middle.
2, 3, 4, 6, 7, 7, 8, 47
In the middle lie numbers 6 and 7. To get the median, find the sum, then divide it by 2.
6 + 7 = 13
13 ÷ 2 = 6.5

The school newspaper wants to do an article about DLDs at DHS by interviewing the Dacula Leadership Team. They wish to get quotes from 8 of the 30 seniors on DLT. 18 of the senior DLT members are athletes, while 12 are non-athletes. Determine the probability that the newspaper staff receives quotes from exactly 3 athletes. Round to two decimal places.
The binomial distribution is applicable when only two outcomes are possible. The probability that the newspaper staff receives quotes from exactly 3 athletes is 0.1238.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]
Where,
x is the number of successes needed,
n is the number of trials or sample size,
p is the probability of a single success, and
q is the probability of a single failure.
Given that 18 of the senior DLT members are athletes, therefore, the probability of a DLT member being an athlete is,
[tex]P = \dfrac{18}{30} = \dfrac{6}{10} = 0.6[/tex]
Also, 12 of the senior DLT members are non-athletes, therefore, therefore, the probability of a DLT member being a non-athlete is,
[tex]q = \dfrac{12}{30} = \dfrac{4}{10} = 0.4[/tex]
Now, using the binomial distribution the probability that the newspaper staff receives quotes from exactly 3 athletes can be written as,
[tex]P(x) = ^nC_x p^xq^{(n-x)}\\\\P(x=3) = ^8C_3\cdot (0.6)^3\cdot (0.4)^{(8-3)}\\\\P(x=3) = ^8C_3\cdot (0.6)^3\cdot (0.4)^{(5)}\\\\P(x=3) = 0.1238[/tex]
Hence, the probability that the newspaper staff receives quotes from exactly 3 athletes is 0.1238.

Step-by-step explanation:
given a quadratic function in standard form
f(x) = ax² + bx + c ( a ≠ 0 ) , then
• if a > 0 , the function opens up and has a minimum
• if a < 0 , the function opens down and has a maximum

then f(x) opens up and has a minimum
Answer:
Option A, open up and have a minimum
Step-by-step explanation:
Step 1: Determine if it opens up or down
Since the value of a is 1/2 which means that it's positive which also means that it opens up. When a parabola opens up, that means that it has a minimum.
The picture attached to this answer shows an example of how a graph would look when using this equation. If a was -1/2 then the parabola would be facing down and would have a maximum.
