Select all the correct answers. Which of the following values satisfy the inequality shown? You must select all that apply.

Answer:

91.72% likely that the soil sample contains organic matter.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have that:

Of 700 samples that contain organic matter, 665 give a positive result and 700 - 665 = 35 give a negative result.

Of 300 samples that do not contain organic matter, 300 - 240 = 60 give a positive result and 240 give a negative result.

If a soil sample test gives a positive result, it is ___% likely that the soil sample contains organic matter.

665 with organic matter out of 665 + 60 = 725 positive tests.

665/725 = 0.9172

0.9172*100% = 91.72%.

91.72% likely that the soil sample contains organic matter.

Answer:

[tex]y = \frac{1}{2} x - 3[/tex]

Step-by-step explanation:

The equation of a line can be written in the form of y=mx +c, where m is the gradient and c is the y-intercept.

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

Using the gradient formula above,

gradient of line

[tex] = \frac{ - 1 - ( - 7)}{4 - ( - 8)} [/tex]

[tex] = \frac{ - 1 + 7}{4 + 8} [/tex]

[tex] = \frac{6}{12} [/tex]

[tex] = \frac{1}{2} [/tex]

Substitute m= ½ into the equation:

y= ½x +c

To find the value of c, substitute a pair of coordinates.

When x= 4, y= -1,

[tex] - 1 = \frac{1}{2} (4) + c[/tex]

-1= 2 +c

c= -1 -2 (-2 on both sides)

c= -3

∴ The equation of the line is y= ½x -3.

Answer:

  $1.74

Step-by-step explanation:

The ratio of the increase to this year's wage is ...

  12%/112% = x/$16.24

Multiplying by $16.24, we have ...

  x = $16.24(12/112) = $1.74

The dollar amount of the wage increase is $1.74.

Answer:

the answer is A

y=6x

Answer:

The answer is 15 ounces

Step-by-step explanation:

33/4 ÷ 4 pounds.

(4 × 3 + 3)/4 ÷ 4 pounds.

15/4 ÷ 4 pounds.

15/4 × 1/4 pounds.

15/16 pounds.

Now we know that, 1 pound = 16 ounces.

So, 15/16 pounds = 15/16 × 16 ounces = 15 ounces.

Thus, The answer is 15 ounces

Answer:

There's no graph in your question!

Answer:

H0 : μ = 18000

H1 : μ < 18000 - - - > Claim

Test value = - 3.578

Critical value = ±2.58

There is significant evidence to accept the claim that mean debt at graduation is less than $18000

Step-by-step explanation:

H0 : μ = 18000

H1 : μ < 18000

From the data:

Sample size, n = 30

Sample mean, x = 16298.37

The test statistic :

(16298.37 - 18000) ÷ (2605/sqrt(30))

−1701.63 / 475.60575

= - 3.578

The critical value :

Using the standard normal table;

Critical value at α = 0.01

Critical value = ±2.58

Decison region :

|test statistic | > |Critical value | ; reject H0

|3.578| > |2.58| ; We reject H0 and conclude that Mean debt at graduation is less than $18000

Answer:

Step-by-step explanation:

3. A single sticky note is a three-dimensional object. Meaning it has a length, width and height. Therefore, it is taking up space, and anything that takes up space has a volume. If the sticky not did not have a volume then it would not be a three-dimensional object.

4. Yes, if we knew the volume of a single sticky note, then we would simply have to multiply the volume of that individual note by the total number of sticky notes in the pile. This would give us the volume of the entire pile.

Answer:

The answer is C.

Step-by-step explanation:

to find the area you need to multiply the width times length, to find the length you need to add the c and 15 and have that mulitplied by 1/5

.

1/5(c+15)

Answer:

The width of the new phone will be of 4.37 inches.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

In this question:

Length was of 2.2 inches, after the modification is of 2.09 inches.

Width was of 4.6 inches, after the modification is x. So

2.2 - 2.09

4.6 - x

Applying cross multiplication:

[tex]2.2x = 2.09*4.6[/tex]

[tex]x = \frac{2.09*4.6}{2.2}[/tex]

[tex]x = 4.37[/tex]

The width of the new phone will be of 4.37 inches.

[tex]11.04\:\mathrm{ft}[/tex]

Step-by-step explanation:

The volume of a cylinder is given by [tex]V=r^2\pi\cdot h[/tex], where [tex]r[/tex] is the radius of the circle that acts as the base of the cylinder and [tex]h[/tex] is the height of the cylinder.

Solving for [tex]h[/tex]:

[tex]3000=9.3^2\pi\cdot h,\\h=\frac{3000}{9.3^2\pi}\approx\boxed{11.04\:\mathrm{ft}}[/tex]

Answer:

It is:

B.Divide the area of the triangle by the base and multiply the result by 2.

Answer:

2.2 × 10³ mm³

Step-by-step explanation:

We have a triangular prism with the following dimensions:

Altitude: 20.5 millimeters

Base: 16 millimeters

Height: 13.3 millimeters

We can calculate the volume of a triangular prism using the following expression.

V = (1/2 × Altitude × Base) × Height

where,

(1/2 × Altitude × Base) is the area of the base

V = (1/2 × Altitude × Base) × Height

V = (1/2 × 20.5 mm × 16 mm) × 13.3 mm = 2.2 × 10³ mm³
