find the area under the standard normal curve between the given zz-values. round your answer to four decimal places, if necessary. z1=−2.02z1=−2.02, z2=2.02

Answers

Answer 1

The area under the standard normal curve between z1 = -2.02 and z2 = 2.02 is approximately 0.9566.

To find the area under the standard normal curve between the given z-values, z1 = -2.02 and z2 = 2.02, follow these steps:

1. Look up the corresponding probabilities in a standard normal distribution table (or use a calculator or software with a built-in z-table) for each z-value.
2. Subtract the probability of z1 from the probability of z2 to find the area between the two z-values.

Step 1: Look up probabilities for z1 and z2
- For z1 = -2.02, the probability is 0.0217
- For z2 = 2.02, the probability is 0.9783

Step 2: Subtract probabilities
- Area between z1 and z2 = P(z2) - P(z1) = 0.9783 - 0.0217 = 0.9566

So, the area under the standard normal curve between z1 = -2.02 and z2 = 2.02 is approximately 0.9566.

Si para introducirun producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200

Answers

Complete question :

si para introducir un producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200 ¿que porcentaje se cobra por impuesto?

Responder:

18,75%

Explicación paso a paso:

Dado que:

Monto cobrado por impuestos = $ 225

Costo del producto sujeto a impuestos = $ 1200

El porcentaje del precio de costo del producto que se grava:

Sea porcentaje = x%

x% * precio de coste = importe de impuestos

0.01x * $ 1200 = $ 225

12x = 225

x = 225/12

x = 18,75

Por tanto, porcentaje de impuesto = 18,75%

Answer:

x=17 and y=23 DONT SUE ME IF I GET THIS WRONG PLZZ ;-;

Step-by-step explanation:

Answer:

(1, - 1 )

Step-by-step explanation:

Given the 2 equations

3x - 2y = 5 → (1)

4x + 3y = 1 → (2)

Multiplying (1) by 3 and (2) by 2 and adding the result will eliminate y- term

9x - 6y = 15 → (3)

8x + 6y = 2 → (4)

Add (3) and (4) term by term to eliminate y

17x + 0 = 17

17x = 17 ( divide both sides by 17 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

4(1) + 3y = 1

4 + 3y = 1 ( subtract 4 from both sides )

3y = - 3 ( divide both sides by 3 )

y = - 1

solution is (1, - 1 )

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.

y=47(0.63)
x

Answers

It represents decay because the term inside the parentheses (which is “b”) is less than one. To find the percentage rate, subtract b from 1 and multiply it by 100.

1-0.63=0.37
0.37(100)=37

So the final answer is 37% decrease.

Answer:

decay function

percent rate of decrease is 37%

Step-by-step explanation:

I assume the x is the exponent.

[tex] y = 47(0.63)^x [/tex]

The number raised to the exponent x is 0.63 which is between 0 and 1. That means that as x increases, (0.63)^x decreases. That means it is an exponential decay function.

Each unit more in x results in 0.63 being multiplied by the number.

Since 1 - 0.63 = 0.37, the percent rate of decrease is 37%.

Answer:

decay function

percent rate of decrease is 37%

Find the measure of Angles A, C, D

Answers

Answer:

A= 65 C= 65 and D= 115

Step-by-step explanation:

given a parallelogram .

interior angles sum is 360 degree.

sum of adjacent angles is 180degree.

opposite angles are congruent (B=D).

A + B + C + D = 360

(A + D) + C + 115 = 360 since A and D are adjacent angles .

180 + 115 + C = 360

295 + C = 360

C = 360 - 295

C = 65

D = 115

A = 65

a+b+c+d=360

65 + 65 + 115 + 115 = 360

130 + 230 = 360

360 = 360
