Answer: the answer is 33/100 or .33
Answer:
33/100
Step-by-step explanation:
Because since 4/10 + ?= 73/100 that means the denominator get's change so we know that the demonter for the ? number had to have 100 as a denominator.
And since that number has a 100 for their demonter that means we times our demonter(10 until it get's to 100 so how many times do we times 10 to it get's to 100? the answer is 10.
So since we times our denominator we also have to times our numerator by 10 as well what is 4 times 10? Our answer is 40.
So now our fraction 4/10 is now 40/100. what= 73 when you add it to 40?
Our answer for that is 33 how I know is 40+ 33= well lets add the tens what is 40 + 30=70 now add ones 3 so 73 and our denominator is already the same and our fraction now is 73/100. and there's our answer.
4/10(40/100 now because of the calculations) + 33/100=73/100 so we figured out our mysterious fraction| Mysterious fraction=73/100.
Hope this helps have a magnificent day:)

Liquid A has a density of 1.42 g/cm³
7 cm³ of liquid A is mixed with 125 cm of liquid B to make liquid C.
Liquid C has a density of 1.05 g/cm³.
Find the density of liquid B.
Give your answer correct to 2 decimal places.
Step-by-step explanation:
if I understand correctly, then we are mixing 7 cm³ of liquid A with 125 cm³ of liquid B to a liquid C.
A has a density of 1.42 g/cm³.
B has a density of x g/cm³.
the resulting C has a density of 1.05 g/cm³.
the first thing we see is the quantity of C :
C = A + B = 7 + 125 = 132 cm³
what "comes in" must also "come out" again.
there is no mentioning of a chemical reaction, that might cause a change of volume or mass of the mixture.
so, the whole is exactly the sum of its ingredients.
now about mass and density :
as also the mass (g) of the resulting C must be the same as the sum of the masses of A and B, we multiply the density by the quantity of every liquid to get the mass (g). and that is how we get then the missing density of B :
7×1.42 + 125x = 1.05×(7+125)
9.94 + 125x = 1.05×132 = 138.6
125x = 128.66
x = 1.02928 ≈ 1.03 g/cm³

The dot plots show the number of points that Sophia and Valerie each scored in the first 10 basketball games. The mean for Sophia's Basketball is 8. 5 points and the mean for Valerie's Basketball games is 15. 5 points. The mean absolute deviation of both distributions is 2 points
Part A: The mean number of points scored by Valerie is 2 or 7 or 8. 5 or 15. 5 greater than the mean numbers of points scored by Sophia.
Part B: What multiple of the mean absolute deviation represents the difference in the mean number of points scored by Sophia and Valerie in the first 10 basketball games?
2. 5
3. 0
3. 5
4. 0
The mean number of points scored is the average of points scored
The mean number of points scored by Valerie is 7 greater than the mean numbers of points scored by Sophia.
How to interpret the mean?The given parameters are:
Mean for Sophia's = 8.5 pointsMean for Valerie's = 15.5 points. Mean absolute deviation of both = 2 pointsCalculate the difference (d) between the mean values
d = 15.5 - 8.5
Evaluate the difference
d = 7
Hence, the mean number of points scored by Valerie is 7 greater than the mean numbers of points scored by Sophia.
The multiple of the mean absolute deviation?In (a), we have:
Mean absolute deviation of both = 2 points
Difference = 7
Express as products
Difference = 2 * 3.5
Hence, 3.5 is a factor of the difference between the mean

x + y = 95. and y is 2/3 of x. find x and y.
Answer:
{x,y}={60,35}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = y + 25
// Plug this in for variable x in equation [1]
[1] (y +25) + y = 95
[1] 2y = 70
// Solve equation [1] for the variable y
[1] 2y = 70
[1] y = 35
// By now we know this much :
x = y+25
y = 35
// Use the y value to solve for x
x = (35)+25 = 60
Answer:
x=57
y=38
Step-by-step explanation:
(1): x+y=95
(2): y=2/3x
substitute y=(2/3)x in equation (1):
x+(2/3)x=95
Multiply both sides by 3
3x+2x=285
5x=285
Divide both sides by 5
x=285/5
x=57
substitute x=57 in equation (2):
y=2/3×57=38
hence: x=57 , y=38

A bicycle store cost 4500$ per month to operate. The store pays an average of 35$ per bike. The average selling price of each bike is 125$.How many bicycles must the store sell each month to break even
Answer:
50
Step-by-step explanation:
let x be the no of bicycles to be sold
125x = 4500 + 35x
125x-35x = 4500

[tex]3\left(-x+3\right)-11[/tex] ← ( Expand)
[tex]14+5x=-3x-2[/tex]
[tex]14+5x-14=-3x-2-14[/tex] ← ( Subtract 14 from both sides)
[tex]5x=-3x-16[/tex]
[tex]5x+3x=-3x-16+3x[/tex]

Answer:
-2Step-by-step explanation:
In the question we have given with an equation that is 14 + 5x = 3 ( -x + 3 ) - 11 .
And we are asked to find the value of x.
Solution : -
[tex] \longmapsto \: 14 + 5x = 3( - x + 3) - 11[/tex]
Step 1 : Solving parenthesis on right side :
[tex] \longmapsto \: 14 + 5x = - 3x + 9 - 11[/tex]
On further calculations we get :
[tex] \longmapsto \: 14 + 5x = - 3x - 2[/tex]
Step 2 :
Subtracting 14 from both sides :
[tex] \longmapsto \: \cancel{14} - \cancel{14 }+ 5x = -3x -2 - 14[/tex]
On further calculations we get :
[tex] \longmapsto \: 5x = - 3x - 16[/tex]
Step 3 : Adding 3x on both sides :
[tex] \longmapsto \: 5x + 3x = - \cancel{ 3x} + \cancel{3x} - 16[/tex]
On further calculations we get :
[tex] \longmapsto \: 8x = - 16[/tex]
Step 4 : Dividing by 8 on both sides :
[tex] \longmapsto \: \frac{ \cancel{8}x}{ \cancel{8}} = \cancel {\frac{ - 16}{8} }[/tex]
We get :
[tex] \longmapsto \: \red{\boxed{ \mathfrak{x = - 2}}}[/tex]
Therefore , value of x is -2 .Verifying :We're verifying our answer by substituting value of x in given equation . So ,
14 + 5x = 3 ( -x + 3 ) - 11 14 + 5 ( - 2 ) = 3 { -( -2 ) + 3 ) - 1114 - 10 = 3 ( 2 + 3 ) - 11 4 = 3 ( 5 ) - 114 = 15 - 114 = 4L.H.S = R.H.SHence , Verified .Therefore , our value for x is valid .

One number is 3 less than 4 times a second number. The difference of the first number and twice the second number is 7. What are the two numbers?
Answer:
x = -11, y = -2
Step-by-step explanation:
There's two equations. Let's say the first number is x, and the second number is y. Then, there is 4y-3 = x, and 2y-x = 7. We plug in 4y-3 for x into the second equation, and we get 2y - (4y-3) = 7. Solving more gets us -2y + 3 = 7. thus, -2y = 4, meaning y = -2. We plug back into the second equation, getting -4 - x = 7. This 11 = -x, or x = -11.

Step-by-step explanation:
”. What this means is that there is less than a 5% probability that the results happened just by random chance, and therefore a 95% probability that a results reflects a meaningful pattern in human psychology. We call this statistical significance, and, statistically speaking, this is a pretty high standard
If this means that there is still a 5% chance those results are due to chance. This, combined with publication bias , are two main contributing factors to the reproducibility crisis.
