Answer:

62400

Step-by-step explanation:

Lets ignore everything above 394 because those numbers are the only ones we are focusing on right now.

94 is not less than 50

94 is bigger than or equal to 50

Round up:

394 ---> 400

= 62,400

Answer:

62,400

Step-by-step explanation:

You would round 90 to the nearest hundred which is 400

Answer:

432

Step-by-step explanation:

To get volume you need to multiply all of the numbers together (Length, height, and width). You need to multiply 6 and 6 (You get 36) and multply the answer by 12 to get 432.

Answer:

[tex] (x_1 = 94 , y_1 = 60)[/tex]

[tex] (x_2 =96 ,y_2 = 66)[/tex]

And we can estimate the slope with the following formula:

[tex] m =\frac{y_2 -y_1}{x_2 -x_1}= \frac{66-60}{96-94}=3[/tex]

And we can find the intercept using the first point given for example:

[tex] 60 = 3*94 +b[/tex]

And solving for b we got:

[tex] b = 60 -282 = -222[/tex]

And the model would be given by:

[tex] y = 3x -222[/tex]

Step-by-step explanation:

For this case we can assume that the interest is find an equation for the times per minute with the temperature. So then the independent variable (x) would be the temperature and the dependent (y) the times per minute. We want to adjust a linera model like this one:

[tex] y = mx +b[/tex]

We have the following info given:

[tex] (x_1 = 94 , y_1 = 60)[/tex]

[tex] (x_2 =96 ,y_2 = 66)[/tex]

And we can estimate the slope with the following formula:

[tex] m =\frac{y_2 -y_1}{x_2 -x_1}= \frac{66-60}{96-94}=3[/tex]

And we can find the intercept using the first point given for example:

[tex] 60 = 3*94 +b[/tex]

And solving for b we got:

[tex] b = 60 -282 = -222[/tex]

And the model would be given by:

[tex] y = 3x -222[/tex]

Answer:

Step-by-step explanation:

Let " x "  denotes the temperature in degree Fahrenheit .

Let  " y " denotes the chirp rate per minute .

We have given that at 94 degree Fahrenheit , chirp rate is 64 times per minute and at 96 degree Fahrenheit , it is 118 times per minute .

We write this information in coordinate form ( x,y) .

We have ( x₁ ,y₁)  = ( 94 , 60 )  and  ( x₂ , y₂) = ( 96,66) .

                        y₂   - y ₁                     66  -   60                  6

Slope , m  =  ----------------------  =    ---------------------  =     -----------

                         x₂  - x₁                        96   -  94                   2

          Slope , m =  6/2 = 3 .

Equation of line in slope intercept form is

y = m x + b  where  ' m' is slope and ' b ' is intercept .

Plug value of m  , we get

y = 3 x + b .

To find value of b , we put ( 94 , 60 ) in place of x and y .

Put x = 94 and y = 60 , we get

60 = 3 * 94 + b

60  = 282 + b

60 - 282 =  b

- 222 = b

Thus we get b = - 222 .

So the equation become

y = 3 x - 222 .

Answer:

x=1  y=3

Step-by-step explanation:

y = 4x - 1

y = -3x + 6

Set the two equations to each other

4x - 1  = -3x + 6

Add 3x to each side

4x +3x - 1  = -3x+3x + 6

7x-1 =6

Add 1 to each side

7x-1+1 = 6+1

7x= 7

Divide each side by 7

7x/7 = 7/7

x=1

Now we can find y

y = 4x-1

y = 4(1)-1

y = 3

Answer:

0.7048

Step-by-step explanation:

∫₂⁴ 1 / (x − 1)² dx

n = 4, so we divide the interval into 4 regions.  The width of the regions is:

(4 − 2) / 4 = 0.5

So the intervals are (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).

Evaluate f(x) at the ends of each interval.

f(2) = 1

f(2.5) = 4/9

f(3) = 1/4

f(3.5) = 4/25

f(4) = 1/9

Find the area of each trapezoid:

A₁ = ½ (2.5 − 2) (1 + 4/9) = 13/36

A₂ = ½ (3 − 2.5) (4/9 + 1/4) = 25/144

A₃ = ½ (3.5 − 3) (1/4 + 4/25) = 41/400

A₄ = ½ (4 − 3.5) (4/25 + 1/9) = 61/900

So the total approximate area is:

A = 0.705

Closest answer is 0.7048.

The value of expression is,

⇒ 0.7048

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

⇒ ∫₂⁴ 1 / (x − 1)² dx

Now, For n = 4, we divide the interval into 4 regions.  

Hence, The width of the regions is:

= (4 − 2) / 4

= 0.5

Thus, the intervals are,

⇒ (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).

Thus, We can evaluate f(x) at the ends of each interval as,

f(2) = 1

f(2.5) = 4/9

f(3) = 1/4

f(3.5) = 4/25

f(4) = 1/9

Hence, the area of each trapezoid are,

A₁ = 1/2 (2.5 − 2) (1 + 4/9) = 13/36

A₂ = 1/2 (3 − 2.5) (4/9 + 1/4) = 25/144

A₃ = 1/2 (3.5 − 3) (1/4 + 4/25) = 41/400

A₄ = 1/2 (4 − 3.5) (4/25 + 1/9) = 61/900

Therefore, the total approximate area is:

A = A₁ + A₂ + A₃ + A₄

A = 0.7048

Answer:

Your answer is going to Be b

Answer:

The softball team needs to raise more money per person.

Step-by-step explanation:

To calculate what you need in each team you have to divide the money you need by the number of players in each team, because each one contributes an equal amount.

The softball team needs to raise $ 318.12 between the twelve girls on the team:

318.12 / 12 = 26.51

$ 26.51 each girl needs to contribute

The hockey team needs to raise $ 391.92 between the 24 boys on the team

391.92 / 24 = 16.33

$ 16.33 each boy needs to contribute

Therefore, the softball team needs to raise more money per person.

A.) 8 is the outlier in the set. It is the only number that doesn't match with the others. It is the furthest from the median of the numbers.

B.) The outlier could represent false information. It could greatly drop the number of the mean, or the average, range of the scores.

C.) The mean is affected more. The mean of a set of numbers is the average of the set. The median just locates the middle-most number. The median would not always give an accurate representation of the average of the set like the mean would.

Answer:

Bronze

Step-by-step explanation:

To know the metal used to produce necklace, we must calculate the density of the necklace. This is illustrated below below:

Mass of necklace = 192g

Volume = 19.5cm^3

Density =...?

Density of a substance is simply defined as the mass of the substance per unit volume.

Density = Mass /volume

Density = 192g / 19.5cm^3

Density = 9.85g/cm^3

Now comparing the density of the necklace with the density of various metals in the table, we can see that the density of the necklace matches that of bronze.

Therefore, the necklace is made of bronze.

Answer:

55°

Step-by-step explanation:

total angle of a triangle is 180°

we are given 2 angles

85+40+ x = 180

180-125 = 55° (x)

Answer:

See below.

Step-by-step explanation:

A(x) = x^2 + 5x

A(x) = x^2 + 5x = 14

x^2 + 5x - 14 = 0

(x + 7)(x - 2) = 0

x + 7 = 0  or  x - 2 = 7

x = -7 or x = 2

x is the height of a rectangle.

The only viable solution is x = 2 because the height of a rectangle cannot be a negative number such as -7.

The only viable solution for the height is x= 2, because height cannot be a negative value.

A rectangle is a quadrilateral with four right angles.

Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is [tex]ax^{2} +bx+c=0[/tex]

Given,

Area of the rectangle = [tex]x^{2} +5x[/tex] = 14

Then,

[tex]x^{2} +5x-14=0\\(x+7)(x-2)=0[/tex]

Therefore x = -7 and 2

But the Height cannot be negative therefore x = 2

Hence, only viable solution for the height is x= 2, because height cannot be a negative value.
