Step-by-step explanation:

A barrel with a 60 liter capacity is half full, therefore there are 30 liters in the barrel.

If we use 240 bottles with a capacity of 1/4 liters, how many liters do we need to fill the 240 bottles?

240 x [tex]\frac{1}{4}[/tex]L = [tex]\frac{240}{4}[/tex] = 60L

Therefore, it is false because we only have 30 liters, we can't fill the 240 bottles

Answer:

option c

Step-by-step explanation:

if y= x^2 e^x then the derivative is x^2 * e^x + e^x * 2x

take e^x and x as commom so we get e^x * x ( x+2)

The approximately 99.7% of the bags will have lengths within 3 standard deviations.

We have given that the weights of 2-pound bags of best dog food are approximately normally distributed with a given mean and standard deviation.

The empirical rule for a normal distribution states that approximately all of the data falls within 3 standard deviations of the mean.

So the approximately 68% data falls within 1 standard deviation of the mean.

and the approximately 95% of data falls within 2 standard deviation of the mean.

Now the approximately 99.7% data falls within 3 standard deviation of the mean.

As the weights of 2-pound bags of best dog food are normally distributed,

Therefore, approximately 99.7% of the bags will have lengths within 3 standard deviations of the mean and option D is the correct choice.

Answer:

The arithmetic means are;

6.5 , 2.75, 4.125 , 4.8125

Step-by-step explanation:

We start by finding the mean of the two numbers;

(14-1)/2 = 13/2 = 6.5

Next;

(-1 + 6.5)/2 = 5.5/2 = 2.75

Next

(2.75 + 5.5)/2 = 4.125

Next;

(4.125 + 5.5)/2 = 4.8125

Answer:

Transitive Property

Step-by-step explanation:

Let's define the following word bank answer choices:

Complementary Angles  ⇒ Angles that add up to 90 degree

Vertical angles ⇒  pair of opposite angles formed by intersecting lines

Reflexive Property ⇒ equality states that a number is always equal to itself

Transitive Property ⇒ All real numbers x ,y, and z, if x=y and y=z , then x=z.

Solve:

Base on the given we know that it not complementary angles because it doesn't form 90 degree (right angle).

We Also know that it not vertical angles because it doesn't  shows angles opposite each other where two lines cross.

In addition, the given doesn't shows If a is a number, then. a = a. a=a.

Thus, Transitive Property is the answer.

Answer:

C

Step-by-step explanation:

When we multiply numbers of the same base regardless of the exponent, we add the exponents together.

So,

[tex]2 {}^{x} \times 2 {}^{y} = 2 {}^{x + y} [/tex]

Similarly for this case multiplying the 3 7's ^1/3 would simply mean we are adding 3 1/3's together, to get 7^3/3, which is essentially 7^1=7

Answer: C and D

Step-by-step explanation:

We need to find all the figures that are rhombuses. These figures are C and D.

The quadrilaterals C and D are those for which the diagonals cross at right angles.

Quadrilateral are closed geometrical shapes having four sides, four angles and four vertices. Some of the common quadrilaterals include rectangles, square, parallelogram and the rhombus.

Interior angles of any type of quadrilateral always sums up to 360°.

Diagonals of a quadrilateral is the straight line formed by joining opposite vertices.

For every quadrilateral, there are two diagonals.

Figure A is a rectangle. The diagonals of a rectangle bisects each other, but is not perpendicular bisector. This means that diagonals of figure A does not cross at right angles.

Figure B is a parallelogram. Properties of diagonals are almost same in rectangles and quadrilateral. Diagonals bisect each other, but is not perpendicular. So diagonals of figure B also does not cross at right angles.

Figure C is rhombus. Diagonals of a rhombus perpendicularly bisect each other. Therefore diagonals of figure C cross at right angles.

Figure D is square. Again the diagonals of a square perpendicularly bisect each other. Therefore diagonals of figure D cross at right angles.

Hence diagonals of figures C and D cross at right angles.

Answer: its the third one

Step-by-step explanation: im preety sure thats it

One criterion that we can use to analyze patterns is to look at the difference between consecutive terms. With this, we will see that the missing number is 361.

For the first two we have:

11 - 10 = 1

for the second and third:

21 - 11 = 10

for the fourth and third:

32 - 21 = 11

for the fifth and fourth:

53 - 32 = 21

We already can see the pattern, the n-th term can be written as:

Aₙ = Aₙ₋₁  + Aₙ₋₂

This means that the missing number, the next one, will just be equal to the sum of the two previous ones.

Then the next number is:

N = 138 + 223 = 361
