3/8 or 37.5 percent, if there were 200 students there would be 75 students who enjoy literature.

The expected value of the defective skateboard will be 4/25. Then the correct option is B.

Probability distribution of a random variable is the collection of value and its probability pair for values of that considered random variable.

It might be a function, a table, etc.

The table is shown below.

Then the expected value of the defected skateboard will be

p = 0 x 9/10 + 1 x 1/20 + 2 x 1/25 + 3 x 1/100

p = 1/20 + 2/25 + 3/100

p = 5/100 + 8/100 + 3/100

p = 16/100

p = 4/25

Hi Student!

The first step that we need to take before trying to solve the problem is that we need to take out important information from the problem.  The first important piece of information that is given to us is that we are trying to find an equation of a line that is parallel to a different line.  This means that our slope is going to be the same as the initial line given.  The second piece of information that is given is a point through which our line passes through which will help us greatly when solving for our line.

The next step that we must take is to solve for y in the given equation so we can see what the slope is.

Subtract 6x from both sides

Divide both sides by 5

Now that we have completely solved for y, we can see that the slope is -1.2 using the y = mx + b formula which states that m is the slope.

Moving onto the next step, we must use the point-slope formula to determine what the new equation is that has the same slope and passes through (-4, -2).

Insert the Values

Simplify the Equation

Distribute the Equation

Subtract 2 from both sides (to isolate y)

Therefore, our final answer for the equation of the line parallel to 6x + 5y = 1 and that passes through (-4, -2) is y = -1.2x - 6.8.

262 Masks

Step-by-step explanation:

190×0.38=72.2 but there cannot be 0.2 masks so it becomes 72. 190+72=262.

The total number of masks in Emma's collection is 262 Masks.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Emma has a mask collection. she keeps 190 of the masks on her wall, which is 38% of her entire collection.

The total number of masks will be calculated as,

190×0.38=72.2

But there cannot be 0.2 masks so it becomes 72.

Total mask = 190+72

Total mask =262.

Therefore, the total number of masks in Emma's collection is 262 Masks.

Answer:

the answer is j because it's impossible to draw a line through the center of any parallelogram that divides the figure into two equal halves that are mirror images of each other

Out of the given options, the shape that does not have a vertical line of symmetry is J. Parallelogram.

The correct answer is J. Parallelogram.

A vertical line of symmetry means that if a line is drawn vertically through the shape, the two halves will be mirror images of each other.

In the case of a line (F), it is one-dimensional and does not have an area, so it does not have any symmetry.

A square (G) has four sides of equal length and four right angles. It has both vertical and horizontal lines of symmetry, dividing it into four congruent quadrants.

A pentagon (H) is a five-sided polygon. Depending on its shape and orientation, it may or may not have a vertical line of symmetry. For example, a regular pentagon does have a vertical line of symmetry, while an irregular pentagon may not.

A parallelogram (J) is a four-sided polygon with opposite sides that are parallel and equal in length. It does not have a vertical line of symmetry because its opposite sides are not mirror images of each other.

A scalene triangle (K) is a triangle with no equal sides or equal angles. It does not have a vertical line of symmetry because its sides and angles are not symmetric.

#TheWizzer

The correct inequality that  has an open circle when it is graphed on a number line is,

1) x greater-than three-fifths

We have to given that,

All the expressions are,

1) x greater-than three-fifths

2) Start Fraction 4 over 7 End Fraction greater-than-or-equal-to x

3) x less-than-or-equal-to 12

4) x greater-than-or-equal-to negative 6.

We can write all the inequality as,

1)  x greater-than three-fifths

⇒ x > 3/5

Since, it has symbol '>' which represent open circle.

Hence, It is true.

2) Start Fraction 4 over 7 End Fraction greater-than-or-equal-to x.

4/7 ≥ x

Since, it has symbol '≥' which represent closed circle.

Hence, It is not true.

3) x less-than-or-equal-to 12

x ≤ 12

Since, it has symbol '≥' which represent closed circle.

Hence, It is not true.

4) x greater-than-or-equal-to negative 6.

x ≥ - 6

Since, it has symbol '≥' which represent closed circle.

Answer:

y=3x-12

Step-by-step explanation:

We need to find the m of y = mx+b which is the slope:

-3-(-6)/3-2 = 3 as our slope

We know have y = 3x+b.

If we keep applying slope to the point (2,-6) and go downwards. We hit (0,-12). That's our y intercept. So we replace b with our y intercept which is -12. We know get y = 3x-12

Answer:

No and the density changes along with the weight.

Answer:

  (a) No. The weight is more than 150 lb.

  (b) No. Density is not a function of volume.

Step-by-step explanation:

The weight of the aquarium is the product of the volume and the density of the contents.

The volume of the aquarium is the product of its dimensions:

  V = LWH = (1.75 ft)(1.75 ft)(1.75 ft) = 1.75³ ft³ = 5.359375 ft³

The weight of its contents, at 72 lb/ft³ will be ...

  (72 lb/ft³)(5.359375 ft³) = 385.875 lb

The aquarium should not be placed on the table. The weight of the aquarium is too great for the load limit of the table.

__

The density of water is the ratio of its mass to its volume. Density does not change with depth or volume. It is essentially constant. (Water is considered to be virtually incompressible. Its density changes slightly with temperature,)

No, the density of the water would not change.

_____

Additional comments

The half-full aquarium would weigh about 385.875/2 lb ≈ 194 lb. This is still too heavy for the table.

The density of water is actually about 62.4 lb/ft³. We assume the extra 10 lb/ft³ might take into account the weight of the aquarium and any gravel or other non-water content.

Hi Student!

Looking at the question, lets extract the important values and information that we believe will be important for this problem.  First of all, we are given the area of a circle which is 9409π and we are told to find the radius (rounding it to the nearest whole number).

Now that we have gathered our information, we can move onto the part of solving for the unknown using the area of a circle formula.  We can do  this by just plugging in the information that we have and solving for r which is the radius.

Plug in the values

Divide both sides by pi to get r^2 by itself

Square root both sides to get down to just r

Therefore, our final answer is that the length of the radius is 97 centimeters which we were able to find using the area and the area of a circle formula.

Using the normal distribution, it is found that the sections that are one standard deviation from the mean are 34 and 40.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 37, \sigma = 3[/tex]

The measures that are one standard deviation from the mean are given by X when Z = -1 and Z = 1, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1 = \frac{X - 37}{3}[/tex]

X - 37 = -3

X = 34

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1 = \frac{X - 37}{3}[/tex]

X - 37 = 3

X = 40

Step-by-step explanation:

   Number of candies that her sister gave = x

Total candies that Pam has now = 27

  x +  15 = 27

       x + 15 = 27

   x + 15 - 15 = 27 - 15

               x  = 12

Answer:

Equations :

27 - 15 = x

15 + x = 27

Step-by-step explanation:

So, we know that 1. Pam starts with 15 candies. and 2. Pam ends up having 27 candies. This means, that she gained candy.

To figure out how many candies her sister gave, her, we have to find the difference between 27 and 15 becuase she goes from having 15 to having 27 after her sister had given some.

x will represent how many cadies Pams' sister had given her :

27 -  15 = x

12 = x

This means Pams' sister gave 12 candies to Pam. To make sure we are correct, we can simply start with how many candies Pam started with (15). And add how many we think her sister added (12)

15 + 12

15 + 12 = 27

Therefore proving, and meaning, that Pams' sister gave her 12 candies.

Possible Equations :

27 - 15 = x

End total (27) minus starting total (15).

15 + x = 27

Starting total (15) plus how many she gained (x) equal to end total (27).
