Answer:

10/4 equals 2 1/2 when simplified.

Step-by-step explanation:

10/4 = 2 2/4 or 2 1/2 when simplified.

This is because, 4 x 2 = 8, and 8 + 2 (or 1/2 of 4) = 10.

A form possesses rotational symmetry, often referred to as radial symmetry, when it maintains its appearance following a partial turn rotation. The right answer is D.

A form possesses rotational symmetry, often referred to as radial symmetry, when it maintains its appearance following a partial turn rotation.

The number of alternative orientations in which an object can seem exactly the same for each revolution is the degree of rotational symmetry of that object.

Because of rotational symmetry, the figure should maintain its original appearance  even when rotated. So a rhombus is the shape that exhibits rotational symmetry. So, D is the right answer.

The logarithmic statement [tex]log_bx=log_bc \cdot log_cx[/tex]  is true.

Logarithm is a mathematical operator that is used to simplify the exponential equations .

The logarithm is exponentiation's opposite function in mathematics. This indicates that the base b of another fixed number, the logarithm of a given number x, is the exponent that must be raised in order to obtain the given number x.

The exponential equation logₓy=n is equivalent to xⁿ=y.

The properties of Logarithmic equations are:

Now the given expression is of the form: [tex]log_bx=log_bc \cdot log_cx[/tex]

We know that [tex]log_bc=\frac{log_nc}{log_nb}[/tex]  and  [tex]log_cx=\frac{log_cx}{log_nc}[/tex]

let n=[tex]log_bc=\frac{log_nc}{log_nb}[/tex]  and p=[tex]log_cx=\frac{log_cx}{log_nc}[/tex]

Now for the right side of the equation we have:

n×p

[tex]log_bc \cdot log_cx[/tex]

This can be written as:

[tex]or, \frac{log_nc}{log_nb}\cdot\frac{log_cx}{log_nc}\\or, \frac{log_cx}{log_nb}\\or, log_bx[/tex]

which is equivalent to the left side of the equation.

Hence the statement [tex]log_bx=log_bc \cdot log_cx[/tex] is true.

The difference of the weight is 1 kg 949 g.

The weight of the two items to find the difference are as follows:

Difference in mathematics is the result of subtracting one number from another.

Therefore, let's convert  the weight .

1000g = 1 kg

32 g =

cross multiply

weight = 32 / 1000

weight = 0.032 kg

1000g = 1 kg

83 g = ?

cross multiply

weight = 83 / 1000 = 0.083 kg

Therefore,

25 kg + 0.032 kg = 25.032 kg

23kg + 0.083 kg = 23.083 kg

Hence,

the difference of the weight = 25.032 kg - 23.083 kg

the difference of the weight = 1.949 kg

Hence,

the difference of the weight = 1 kg 949 g

Answer:

You chose the correct option on the picture

x = -4; x = 12

Step-by-step explanation:

You solve for x by simplifying both sides of the equation, then isolating the variable.

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x + 4 = 0
x − 12 = 0

Set x + 4 equal to 0 and solve for x.

Set x+4 equal to 0.

x+4=0

Subtract 4 from both sides of the equation.

x = −4

Set x − 12 equal to 0 and solve for x.

Set x−12 equal to 0.

x−12=0

Add 12 to both sides of the equation.

x=12

The final solution is all the values that make (x+4)(x−12)=0 true.

x=−4,12

Answer:

A.

positive and negative 5 and square root of 29

Answer:

A: Yes, because the chance of rain on Monday and the chance of rain on Tuesday are independent.

Step-by-step explanation:

We are given;

chance of rain next week on Monday is 50%. Thus;

P(rain next Monday) = 0.5

chance it rains on Tuesday is 80%. Thus;

P(rain next Tuesday) = 0.8

From independent events, we can say that;

P(A and B) = P(A) × P(B)

A and B are independent events because the probability of A doesn't affect B as is the case for rain on Monday and Tuesday given.

Thus;

P(rain on Monday & tuesday next week) = 0.5 × 0.8 = 0.4

This can also be written as 40%

Correct answer is option A since both events are independent

Answer: 70

Step-by-step explanation:

Given that :

Uniform range of distribution = 50 to 100

50 ≤ x ≤ 100

Difference between both values = 100 - 50 = 50

Range / difference = computer generated value

(Weekly demand - lower limit) / difference = computer generated value

(Weekly demand - 50) / 50 = 0.4

Weekly demand - 50 = 20

Weekly demand = 20 + 50

Weekly demand = 70

The weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70

A uniformly distributed random variable's probability is distributed uniformly in the interval in which it is defined. Thus, if X ranges from a to b, and pertains uniform distribution, then its probability density function is given by;

[tex]f(x) = \dfrac{1}{b-a}; a < x < b\\\\f(x) = 0; x < a , b < x[/tex]

For the given case,  the weekly demand(let it be tracked by random variable X) is in range 50 to 100.

The computer generated value shows:

[tex]\text{Computer generated value} = \dfrac{\text{Weekly demand} - \text{Lower limit}}{\text{difference between upper and lower limit}}[/tex]

(computer generated value is showing in range 0 to 1, the part occupied by the weekly value from starting, here as it is 0.4, so it means out of 50 values, it is 0.4 = 40% of (100 -50) = 20 (from start which is 50, thus, 50 + 20  = 70) )

As we've got:

Thus, the weekly demand is obtained as:

[tex]0.4 = \dfrac{\text{Weekly demand} - 50}{50}\\\\\text{Weekly demand} = 0.4 \times 50 + 50 = 70[/tex]

Thus, the weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70
