Answer:

The correct answer is B, also may be Brain??

Step-by-step explanation:

The perimeter of a rectangle can be calculated using the formula P = 2l + 2w, where l is the length and w is the width. If the length of the rectangle is 25 cm and we want the perimeter to be greater than 90 cm, we can set up an inequality to solve for the width: 2l + 2w > 90.

Substituting the value for the length gives 2 * 25 + 2w > 90, which simplifies to 50 + 2w > 90. Subtracting 50 from both sides gives 2w > 40, and dividing by 2 gives w > 20.

So the width of the rectangle must be greater than 20 cm to make the perimeter greater than 90 cm. The correct answer is B: width > 20 cm.

Answer:

i'm guessing this but not 100% sure

Step-by-step explanation:

Let w = the width

P = 2l + 2w

2w + 2(25) > 90

2w + 50 > 90

2w > 40

w > 20 cm

Answer:

\(21\frac{1}{8}\)

Step-by-step explanation:

1)  Add the whole numbers first.

\(20+\frac{5}{8}+\frac{1}{2}\)

2) 2 Find the Least Common Denominator (LCD) of\(\frac{5}{8},\frac{1}{2}\). In other words, find the Least Common Multiple (LCM) of 8,28,2.

Method 1: By Listing Multiples

1- List the multiples of each number.

Multiples of 8 : 8, ...

Multiples of 2 : 2, 4, 6, 8, ...

2- Find the smallest number that is shared by all rows above. This is the LCM.

LCM = 88

Method 2: By Prime Factors

1- List the prime factors of each number.

Prime Factors of 8 : 2, 2, 2

Prime Factors of 2 : 2

2- Find the union of these primes.

2,2,2

3- Multiply these numbers: 2 * 2 * 2 = 8. This is the LCM.

LCM = 8

As a result,

LCD = 8

3) Make the denominators the same as the LCD.

\(20+\frac{5}{8}+\frac{1\times 4}{2\times 4}\)

4) Simplify. Denominators are now the same.

\(20+\frac{5}{8}+\frac{4}{8}\)

5) Join the denominators.

\(20+\frac{5+4}{8}\)

6)  Simplify.

\(20+\frac{9}{8}\)

7) Convert \(\frac{9}{8}\)  to mixed fraction.

\(20+1\frac{1}{8}\)

8) Simplify

\(21\frac{1}{8}\)

Answer:

21 1/8

Step-by-step explanation:

11 1/8 = 11.625

9 1/2 = 9.5

11.625 + 9.5 = 21. 125

21.125 = 21 125/1000

21 125/1000 = 21 1/8

Therefore, the probability that a woman will give birth to two boys is only one in three, whereas the probability that a man will do so is one in two.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Here,

The woman may have at least one boy in the three following ways: 1) older boy, younger girl; 2) older girl younger boy; 3) older boy, younger boy.

But the man's children may be distributed in only two ways: 1) older boy, younger girl; or 2) older boy, younger boy.

So the chances are only 1 out of 3 that the woman has two boys, but the chances are 1 out of 2 that the man has two boys.

The cubic function can be graphed using the function behavior and the points.

x   0    1     2        3      4

y   0  −4   −12   −18  −16

Put  x = 0.

Replace the variable x with 0 in the expression.

\(f(0)=(0)^3-5(0)^2\)

Raising 0 to any positive power yields 0.

f(0) = 0 − 5⋅0

f(0) = 0

y = 0

Put x = 1.

Replace the variable x with 1 in the expression.

\(f(1)=(1)^3-5(1)^2\)

f(1) = 1− 5⋅1

f(1) = −4

y = −4

Put x = 2.

Replace the variable x with 2 in the expression.

\(f(2)=(2)^3-5(2)^2\)

\(f(2)=8-5(2)^2\)

f(2) = 8 − 5⋅4

f(2) = −12

y = −12

Put x = 3.

Replace the variable x with 3 in the expression.

\(f(3)=(3)^3-5(3)^2\)

f(3) = 27 − 45

f(3) = −18

y = −18

Put x = 4.

Replace the variable x with 4 in the expression.

\(f(4)=(4)^3-5(4)^2\)

\(f(4)=64-5(4)^2\)

f(4) = 64 − 5 ⋅16

f(4) = 64 − 80

f(4) = −16

y = −16

The cubic function can be graphed using the function behavior and the points.

Answer:

Step-by-step explanation:

The equation f(x) = 3x^2 + 4x + 3 is a quadratic function. Here are three ways this equation can be used in the real world:

In physics, this equation can be used to model the height of an object thrown into the air. The equation f(x) = 3x^2 + 4x + 3 can be used to calculate the height of the object at any given time x, where x is the time elapsed since the object was thrown. The coefficient 3 in the equation represents the acceleration due to gravity, and the other terms represent the initial height and velocity of the object.

In economics, this equation can be used to model the profit of a company. If x represents the number of units sold, then f(x) = 3x^2 + 4x + 3 can be used to calculate the profit made by the company at any level of sales. The coefficient 3 in the equation represents the fixed costs of the company, while the other terms represent the variable costs and revenue.

In engineering, this equation can be used to model the trajectory of a projectile. The equation f(x) = 3x^2 + 4x + 3 can be used to calculate the distance traveled by a projectile at any given time x, where x is the time elapsed since the projectile was launched. The coefficient 3 in the equation represents the initial velocity of the projectile, and the other terms represent the effects of air resistance and gravity.

The solution of the given problem of equation comes out to be total cost for 942 minutes is $1044.

The similar symbol (=) is used in arithmetic equations to signify equality between two statements. It is shown that it is possible to compare various numerical factors by applying mathematical algorithms, which have served as expressions of reality. For instance, the equal sign divides the number 12 or even the solution y + 6 = 12 into two separate variables many characters are on either side of this symbol can be calculated. Conflicting meanings for symbols are quite prevalent.

Part A:

To find an equation,

Where x is number of monthly minutes.

and y is total monthly of splint plan.

\(\rightarrow\bold{173 = 380x + b}\)

Second case:

\(\rightarrow\bold{249= 570x + b}\)

Solve for x:

\(\rightarrow{173 - 380\text{x}=249- 570\text{x}\)

\(\rightarrow{-207=-321\)

\(\rightarrow \text{x} =\dfrac{321}{207}\)

Answer:

Step-by-step explanation:

Pythagoras :

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90 degree angle).

a and b are the side legs.

so, here we have

14² = 6² + b²

196 = 36 + b²

160 = b²

b = sqrt(160) = sqrt(16×10) = 4×sqrt(10) = 12.65

\( E(100 Y^2) =100 E(Y^2)\)

And we have that :

\( E(Y^2) =\sum_{i=1}^n X^2_i P(X_i)\)

And replacing we got:

\( E(Y^2) =0^2 *0.6 + 1^2 *0.25 +2^2*0.10 +3^2 *0.05 = 1.1\)

And finally we have:

\( E(100 Y^2) =100 *1.1 = 110\)

Step-by-step explanation:

For this case we have the following probability masss function given:

Y         0           1              2             3

p(Y)    0.6        0.25      0.10         0.05

And we can define the surcharge with this expression \( 100Y^2\)

We want to find the expected value for the last expression and we can do it on this way:

\( E(100 Y^2) =100 E(Y^2)\)

And we have that :

\( E(Y^2) =\sum_{i=1}^n X^2_i P(X_i)\)

And replacing we got:

\( E(Y^2) =0^2 *0.6 + 1^2 *0.25 +2^2*0.10 +3^2 *0.05 = 1.1\)

And finally we have:

\( E(100 Y^2) =100 *1.1 = 110\)
