Answer:

7 bottles of glue

Step-by-step explanation:

63/9= 7

every time there are 9 sticks, there is one bottle.

Answer:

7 glue bottles

Step-by-step explanation:

Ratio of glue sticks to glue bottles = 9 : 1

Therefore, 9x : 1x

If there are 63 glue sticks in total:

⇒ 9x = 63

⇒ x = 7

Therefore, glue bottles = 1x = 1 × 7 = 7

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.

The given parameters are:

Calculate 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.

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

Answer:

2/3

Step-by-step explanation:

so, you have a circle and if you divide it into 3 equal sections each of those sections take only 1/3 of the circle.

1/3 + 1/3 + 1/3 = 1

if one of the thirds is green then the probability of it landing on another color would be 2/3 being the other two colors.

There are 18 cameras that will be necessary to cover the entire store, the correct option is D.

A unitary method is a method by which we can find the value of one unit from the value of many units and the value of many units from the value of one unit.

Given

Marina wants to install security cameras in her store, which has dimensions 48 feet by 48 feet.

Each camera can view an area of approximately 128 ft2, with a viewing area shaped like a right triangle.

The distance between grid lines is 4 feet.

From the information given, the area of the store roof will be:

= 48 × 48 =  2304 ft²

The area viewed by the camera = 112.5ft²

The number of cameras that will be necessary to cover the entire store is;

[tex]= \dfrac{2304}{128}\\\\= 18[/tex]

Hence, there are 18 cameras that will be necessary to cover the entire store.

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

Answer:

x=-2

Step-by-step explanation:

[tex]14+5x=3\left(-x+3\right)-11[/tex]

[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]

[tex]8x=-16[/tex]

[tex]\cfrac{8x}{8}=\cfrac{-16}{8}[/tex]  ← ( Divide both sides by 8)

[tex]x=-2[/tex]

~

Answer:

Step-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]

We're verifying our answer by substituting value of x in given equation . So ,

Therefore , our value for x is valid .

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

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.

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.

When the results of research investigations affect whether or not they are published, it is known as publication bias.
