A normal curve with a peak at 0 is shown. The area under the curve shaded is negative 2 to negative 1. Z Probability 0. 00 0. 5000 1. 00 0. 8413 2. 00 0. 9772 3. 00 0. 9987 0. 02 0. 14 0. 34 0. 84.

Answers

Answer 1

The area under the shaded region from 1 to 2 is 0.14

What will be the shaded region area?

Probabilities actually define the percentage of the happening of an event

Here the shaded region shows  the probability of the z-scores

The shaded region 1 to 2 is represented as:

[tex]P(1 < z < 2)[/tex]

By using the probability of z-score we can have

[tex]P(1 < z < 2)=P(z < 2)-P(z < 1)[/tex]

From the given standard normal table:

[tex]P(z < 2)=0.9772[/tex]

[tex]P(z < 1)=0.8413[/tex]

So, we have:

[tex]P(1 < z < 2)=0.9772-0.8413[/tex]

[tex]P(1 < z < 2)=0.1359[/tex]

The approximated value will be

[tex]P(1 < z < 2)=0.14[/tex]

Thus the area under the curve shaded is 1 to 2 is 0.14

Convert the following equation into standard form. ​

Answers

[tex]y = - \frac{4x}{9} + 3[/tex]

Move the expression to the left-hand side and change its sign

[tex]y + \frac{4x}{9} = 3[/tex]

Multiply both sides of the equation by 9

[tex]9y + 4x = 27[/tex]

Use the commutative property to reorder the terms

[tex] \underline{ \underline{4x + 9y-27 = 0}}[/tex]

Standard form of a line:-

Ax+By+C=0

[tex]\\ \rm\Rrightarrow y=\dfrac{-4x}{9}+3[/tex]

[tex]\\ \rm\Rrightarrow y=\dfrac{-4x+27}{9}[/tex]

Lucy bought a table on sale for $665. This price was 24% less than the original price.
What was the original price?

Answers

Answer: Below

Step-by-step explanation:

24% is basically 0.24. Since we want to find the original price we make the equation:

x * (1 - 0.24) = 665

For x is the original price. Simplify:

x * (0.76) = 665

x = 665/0.76

x = 875

Our answer is 875

Identify the value of y.
9y+6 = 3y+3+7+26

Answers

Answer:

y=5

Step-by-step explanation:

9y+6 = 3y+3+7+26

arrange the equation so all values with y are on one side, and all regular numbers are on the other side. Make sure you change the sign when changing sides.

9y - 3y = 3 + 7 + 26 -6

6y / 6 = 30 / 6

Now divide both sides by 6 in order for y to be alone.

y = 5

Mrs. Gildner took a survey of the 30 students in her math class. Of the 30 students surveyed, 18 of them said that chocolate is their favorite ice cream flavor. 4 students listed vanilla as their favorite flavor. The remaining students indicated that strawberry is their favorite kind of ice cream.


What is the ratio of chocolate to strawberry? SIMPLIFY if possible!

Answers

Answer: 9:4

Step-by-step explanation: Total is 30. Add 18 and 4 to see how many students were already surveyed, (22) and then subtract that from 30. Then you get 8, so the ratio is 18:8. Then simplify by dividing both numbers by 2, so you get 9:4. Hope that helps :)

What is an equation of the line that passes through the points (5,2) and (-5,-6) PLEASE ANSWER

Answers

Answer:

y = 4/5 x - 2

Step-by-step explanation:

Find for slope first:

m = (y2 - y1) / (x2 - x1)

= [(-6) - 2] / [(-5) - 2]

= -8/-10

= 4/5

Solve for b. Use (5, 2)

y = mx + b

2 = 4/5 (5) + b

2 = 20/5 + b

2 = 4 + b

2 - 4 = b

-2 = b

Substitute the value of m and b.

y = mx + b

y = 4/5 x + (-2)

y = 4/5 x - 2

Solve using substitution.

4x + y = –11
4x + 4y = 16
