Answer:

C. x = 3, y = -6 is the answer.

Step-by-step explanation:

1. Isolate x for x = 2y = 15 -> x = 15 + 2y

2. Substitute x = 15 + 2y -> [2 (15 + 2y) + 4y = -18]

3. Simplify -> [30 + 8y = -18)

4. Isolate y for 30 + 8y = -18 -> y = -6

5. For x = 15 + 2y, substitute y = -6 -> x = 15 + 2(-6)

So, x = 3 and y = -6 are the solutions to this system of equations.

Answer:

"0.0125" is the right solution.

Step-by-step explanation:

The given values are:

Random sample,

n = 90

Claims,

p = 20%

or,

  = 0.20

By using normal approximation, we get

⇒  [tex]\mu = np[/tex]

On substituting the values, we get

⇒      [tex]=90\times 0.20[/tex]

⇒      [tex]=18[/tex]

Now,

The standard deviation will be:

⇒  [tex]\sigma=\sqrt{np(1-p)}[/tex]

On putting the above given values, we get

⇒      [tex]=\sqrt{90\times 0.20\times (1-0.20)}[/tex]

⇒      [tex]=\sqrt{18\times 0.8}[/tex]

⇒      [tex]=\sqrt{14.4}[/tex]

⇒      [tex]=3.7947[/tex]

hence,

By using the continuity correction or the z-table, we get

⇒  [tex]P(x < 10) = P(x < 9.5)[/tex]

⇒  [tex]P(x < 10) = P(\frac{x-\mu}{\sigma} -\frac{9.5-18}{3.7947} )[/tex]

⇒  [tex]P(x < 10) = P(Z < -2.24)[/tex]

From table,

⇒  [tex]P(x < 10) = 0.0125[/tex]

Answer:

6.3

Step-by-step explanation:

Two sides are 9.6 meters long. The perimeter is 31.8 meters.

31.8-9.6-9.6=12.6 the remaining two sides.

12.6/2=6.3 represents the lengths of the other twp sides.

Answer:12.2

Step-by-step explanation:31.8-(9.6x2)=12.2

Answer:

x= -1/5y+9/5

Step-by-step explanation:

5x+y=9

Step 1

First you need to add -y to both sides, basically subtracting y

5x+y-y= 9-y

Step 2

Divide both sides by 5, or multiply by 1/5. You want to do this because to cancel out 5, so you multiply the reciprocal, or divide the constant.

1/5*5x=-y+9/5

Then, you will get the answer

Step-by-step explanation:

just plug in the points on the line into y2-y1/x2-x1

Answer:

The directed number suggested is +3.

Step-by-step explanation:

A directed number is one that has either a positive or negative sign, so that it could be easily located on the number line. Thus, the sign shows the direction of the number. Examples are: -2, -1, +5, +6 etc.

From the given question, let the initial weight be represented by W, then:

I gained 3 pounds implies at that; 3 pounds was added to my initial weight. Thus, my present weight is my initial weight + 3 pounds.

i.e I gained 3 pounds ⇒ W + 3

So that the directed number suggested by the statement is +3.

Answer:

A. The range of both data sets is 40

Step-by-step explanation:

Range = the maximum value - the minimum value

✔️For the Seventh-Grade Students' data set,

Maximum value = 45

Minimum Value = 5

Range = 45 - 5 = 40

✔️✔️For the Eight-Grade Students' data set,

Maximum value = 45 (the value at the whisker to your far right)

Minimum Value = 5 (value indivl ated by the whisker on your far left)

Range = 45 - 5 = 40

Therefore, the two data sets can be described as having the same range of 40.

See attachment for cube

Step-by-step explanation:

Given

[tex]Length = 6cm[/tex]

[tex]Width = 3cm[/tex]

[tex]Height = 2cm[/tex]

Required

The net of the cuboid

A cuboid has 6 faces.

The dimension of these faces are:

Length and Width; Length and Height;

Length and Width; Length and Height;

Width and Height; Width and Height;

This means that the faces will have the following dimensions:

6cm by 3cm; 6cm by 2cm

6cm by 3cm; 6cm by 2cm

3cm by 2cm; 3cm by 2 cm

Taking into account the above measurements and dimensions, you draw 6 faces, then join similar sides lengths.

Answer:

15 men * 12 days = 180 man-days

180 man-days / 9 men = 20 days

From a project management stand point man-days doesn’t really equate to much so while you can evaluate schedule, you would typically desire to see more information than this.

P=k/Q²

K=P×Q²

Where P=9

Q=8

K=?

K=9×8²

K=9×64

K=573

So where K= 573

Q=3

P=?

P=K/Q²

P=573/3²

P=573/9

P=63.67

Answer:

$10.79

Step-by-step explanation:

x =  original cost of one t shirt

We can build this equation

x - (20/100) x + 3x- 5 = 36

-1/5x + 4x = 41

-x + 20x = 205

19x  = 205

x = $10.79

9514 1404 393

Answer:

Step-by-step explanation:

The equation representing either purchase will multiply the number of items by their cost, for each item, and show the total as the cost of the purchase. Here, p is defined as the cost of a pretzel; g is defined as the cost of a granola bar.

Landon's purchase

 1 pretzel + 5 bars will cost 1p +5g

 That cost is 17.55, so the equation is ...

     p +5g = 17.55

Lesley's purchase

  4 pretzels + 2 gars will cost 4p +2g

  That cost is 13.50, so the equation is ...

     4p +2g = 13.50

__

To solve, you can subtract the second equation from 4 times the first:

  4(p +5g) -(4p +2g) = 4(17.55) -(13.50)

  18g = 56.70 . . . . collect terms

  g = 3.15 . . . . . . . . divide by 18

Then the cost of a pretzel can be found using the first equation.

  p + 5(3.15) = 17.55

  p = 1.80

The cost of a pretzel is $1.80; the cost of a granola bar is $3.15.
