Answer:

C) A cut parallel to the vertical axis, directly through the vertical axis

Step-by-step explanation:

If you were to cut this figure in half vertically, the view from the front would be a triangle.

To produce a triangle square pyramid should be cut parallel to the vertical axis, but of the vertical axis option (D) A cut parallel to the vertical axis, but off the vertical axis is correct.

In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the square's joints at the top, which is perpendicular to the center of the square.

As we know, geometry can be defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

We have a square pyramid shown in the picture.

We must cut along to the vertical axis but off the vertical axis in order to create a triangle from the square pyramid.

Thus, to produce a triangle square pyramid should be cut parallel to the vertical axis, but of the vertical axis option (D) A cut parallel to the vertical axis, but off the vertical axis is correct.

Answer:

5

Step-by-step explanation:

Range is calculated by Taking the highest value number (1) and the lowest number(-4) and subtracting both the numbers.

Answer:

Step-by-step explanation:

As we know that

range= largest -smallest value

So

-4=smallest value

-1=largest value

-4-1=-5

They are different values. The 6 in 45,369 is in the tens place while the 6 in 67,420 is in the ten thousand place.

Answer:

a)to find mean

(sum the scores, divide by the number of scores) that is

( 2+ 2 + 0 + 5 +1 +, 4,+ 1, + 3, + 0,+ 0+ , 1, +4, + 4, + 0,+ 1, + 4, +3,+ 4, + 2,+ 1, +0)/21

= 42/21

= 2

b)

median means order the scores numerically then you choose the score in the middle and that is 2

c)sum of squared deviations is done by take difference between each score and the mean, square the result That is

Summation (xbar - x)²

add the final answer is 56

d)variance is gotten by taking sum of squared deviations, divide by (n-1))=

Summation (xbar - x)²/n-1

=2.8

e)standard deviation is square root of variance)= √V = 1.6

Answer:

x=0 or x=−4

Step-by-step explanation:

Let's solve your equation step-by-step.

(x+2)2=4

Step 1: Simplify both sides of the equation.

x2+4x+4=4

Step 2: Subtract 4 from both sides.

x2+4x+4−4=4−4

x2+4x=0

Step 3: Factor left side of equation.

x(x+4)=0

Step 4: Set factors equal to 0.

x=0 or x+4=0

x=0 or x=−4

Answer:

EF = 58

Step-by-step explanation:

From the question given, we obtained the following information:

DF = 9x – 39

DE = 47

EF = 3x + 10

EF =?

We'll begin by calculating the value of x.

This can be obtained as follow:

DF = DE + EF

DF = 9x – 39

DE = 47

EF = 3x + 10

DF = DE + EF

9x – 39 = 47 + 3x + 10

9x – 39 = 47 + 10 + 3x

9x – 39 = 57 + 3x

Collect like terms

9x – 3x = 57 + 39

6x = 96

Divide both side by 6

x = 96/6

x = 16

Finally, we shall determine the value of EF as follow:

EF =?

x = 16

EF = 3x + 10

EF = 3(16) + 10

EF = 48 + 10

EF = 58

Answer:

The answers is below in bold.

Step-by-step explanation:

(a) A = 180 - 25.6 - 124.4 = 30 degrees.

Next use the Sine Rule:

b / sin B = c / sin C

b / sin 25.6 = 39.2/sin 124.4

b = (39.2 * sin 25.6) / sin 124.4

b = 20.53 m.

Also

a / sin A = c / sin C

a / sin 30 = 39.2 / sin 124.4

a =  (39.2 * sin 30 / sin 124.4

a = 23.75 m.

b). This is solved in a similar way to (a).

First find angle C  using the sine rule.

Then you will know angle A  from the 180 degree Rule.

Then you can find the length of  a using the Sine Rule.

Respuesta: Es más probable sacar un mango.

Explicación:

La probabilidad se refiere a la posibilidad de que un evento occura y no otro. En el caso que se describe, la probabilidad de sacar cada fruta puede ser calculada dividiendo el total de cada fruta en el número de frutas totales:

Probabilidad de sacar un mango:

[tex]\frac{cantidad de mangos}{cantidad de frutas en la canasta}[/tex] =  [tex]\frac{30}{50}[/tex]  =[tex]0.6[/tex]

Probabilidad de sacar una piña:

[tex]\frac{cantidad de pinas}{cantidad de frutas en la canasta} = \frac{20}{50}[/tex] [tex]= 0.4[/tex]

De acuerdo a lo anterior la probabilidad de sacar un mango es de 0.6 o de 60% (multiplica la probabilidad por 100 para saber su equivalente en porcentaje), mientras que la probabilidad de sacar un mango es de 0.4 o 40% lo cual es mucho más bajo. Es decir que es más probable sacar un mango.

Answer:

A

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=x^2-1\\g(x)=\sqrt x[/tex]

And we want to find:

[tex](f\circ g)(1)[/tex]

This is the same as:

[tex]f(g(1))[/tex]

So, to find the answer, find g(1) first:

[tex]g(x)=\sqrt x\\g(1)=\sqrt1\\g(1)=1[/tex]

Now, substitute this value for g(1):

[tex]f(g(1))\\=f(1)[/tex]

And plug this into f(x):

[tex]f(x)=x^2-1\\f(1)=(1)^2-1\\f(1)=1-1=0[/tex]

Therefore:

[tex]f(1)=f(g(1))=(f\circ g)(1)=0[/tex]

Our answer is A

Answer:

  J Darren earns $17.35 per hour at his job. How many hours does he need to work in order to earn more than $624.60?

Step-by-step explanation:

You're looking for a situation in which the number 17.35 needs to be multiplied by an unknown quantity.

Scenarios F and G involve addition of 17.35 to something.

Scenario H would correspond to the inequality ...

  17.65x < 624.60

The sign of the given inequality is >, so scenario H is not the one.

__

In scenario J, Darren's total earnings for x hours will be 17.35x, and we want to find x such that this total is greater than 624.60. This matches the given inequality:

  17.35x > 624.60 . . . . . . answer choice J

Greetings from Brasil...

Given the function:

F(X) = 3X

We know that F(X) = Y, so rewriting the function:

Let's check what is the inverse function of F(X). Just change the X for the Y and vice versa

Y = 3X

X = 3Y     isolating Y

Y = X/3

So the inverse of function F(X) is

Answer:

$2600

Step-by-step explanation:

Given that:

the employee earns $50,000 in  a year

The amount of money on wages paid by the employee towards social security = 5.2% of their gross wage

= [tex]\dfrac{ 5.2 \times 50000}{100}[/tex]

= $2600

if an employee makes $50,000 in  the year, he will pay $2600 towards social security.

The other employees that paid 7.3% of their gross wages will not be regarded since they're paying it from their own fund.

Answer:

(E) None of the above

Step-by-step explanation:

The statistic provided is that of the population but the statistic you seek is that of the sample.

Looking at the statistic itself, Variance is the square of Standard Deviation or standard deviation is the square root of variance.

Hence you calculate the standard deviation of the population mean:

√144 = 12

The population standard deviation of/from the mean value is 12.

It could be possible to decipher the sample mean from population mean but not sample size.

So, you can't pick just any answer. Population size should be given first.

5(x+x)=2(3)+3

Step-by-step explanation:

The expression in other way can be written as  5* (3 larger + 6 small stickers)

An expression is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division. The structure of an expression is: Expression is (Number/Variable, Math Operator, Number/Variable)

for example:

An example of a mathematical expression with a variable is 2x + 3. All variables must have a coefficient, a number that is multiplied by the variable. In the expression 2x + 3, the coefficient of x is the number 2, and it means 2 times x plus 3

Given:

Rodrigo placed 3 large stickers on each of 5 pages in his sticker book. Then he placed 6 small stickers on each of the 5 pages,

5 * 3 + 5 * 6

Using distributive property,

a* b + a* c = a* ( b + c)

So,

5* ( 3+ 6)

= 5* 9

=45

also, the another way is

As the pages in both case is 5.

So,  5* (3 larger + 6 small stickers)

Answer:

Step-by-step explanation:

Given data          

Sample Mean (M):  $48.77  

Sample Size (n): 20

Standard Deviation (σ) :  $17.58

Confidence Level: 80%

 we know that z*-Values for 80% Confidence  Levels is 1.28

the expression for margin of error is given bellow\

MOE= z*σ/√n

We can now substitute into the expression and solve for the MOE as

MOE= 1.28*17.58/√20

MOE= 22.502/4.47

MOE= 22.502/4.47
