Which number is a solution of the inequality 8 – 14b ≥ 27?

Answer:

Interval Ratio

Step-by-step explanation:

In statistics, the level of measurement used for a variable determines the what summary statistics and analysis are possible. There are three types of level of measurement.

Nominal

Ordinal

Interval/ Ratio

The nominal is the most basic level of measurement. It is known as categorical or qualitative. Examples includes, numbers,color, sex.  Nominal can be stored as a word or text  or given a numerical code.However, the number do not imply order. They are usually expressed in percentage

Ordinal  are variables based on ranks, they are usually have a meaningful order but the intervals between the variables may not be equal. They are usually expressed in frequencies.

The interval/ratio level of measurement  is the most precise level of measurement. Data can be measured and ordered. Examples include, number of customers, age, weight or size. Interval / Ratio data is also known as scale, parametric or quantitative. Interval / Ratio can be discrete  with whole numbers or continuous with fractional numbers.

Answer:

17.1 kg

Step-by-step explanation:

One stack of rice = 26.3 kg

Two stacks of rice = 2 *26.3  = 52.6 kg

Remaining rice at end of day = Total weight of two stacks - quantity of rice sold in day

= 52.6 - 35.5

= 17.1 kg

Answer:

see below

Step-by-step explanation:

4c + 5 = 27

1.  5 is the calories that come from something else besides carbohydrates in the one bite.

2.

Test the values 8 and 3

4*8 +5 = 32+5 = 37  this does not equal 27

4*3+5 = 12+5 = 17   this does not equal 27

neither 8 nor 3 are solutions

3.  

4c + 5 = 27

Subtract 5 from each side

4c + 5-5 = 27-5

4c = 22

Divide each side by 4

4c/4 = 22/4

c =5.5

Answer:

A. The 5 would stand for the other ingredients.

B. She is correct since if you plug in those numbers for c they would be wrong

C. 5.5

Step-by-step explanation:

A. The 5 would stand for the other ingredients.

    The reason that it is the other ingredients since it is the only other possible answer

B. She is correct since if you plug in those numbers for c they would be wrong

C. 5.5

To do this you would just subtract 5 from both sides leaving you with 4c=22 then you would divide 4 from both sides so you get c= 22/4 and when you simplify you get 11/2 which as a number is 5.5

Answer:

see explanation

Step-by-step explanation:

They are collinear if the have the same slope

(2 - -1)/(5 - 1) = 3/4

(5 - 2)/(9 - 5) = 3/4

(5 - -1)/(9 - 1) = 6/8 = 3/4

Step-by-step explanation:

Hey, there!!!

Your question is about showing the points A(1,-1), B(5,2) and C(9,5) as a collinear point.

We generally slope to find weather the points are collinear or not.

So, let's find slope for AB.

[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]

[tex] slope = \frac{2 + 1}{5 - 1} [/tex]

Therefore, slope of AB = 3/4.

Now, slope of BC.

[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]

[tex]slope \: (m) = \frac{5 - 2}{9 - 5} [/tex]

Therefore, the slope is 3/4.

now, lastly slope of AC.

[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]

[tex]slope(m) = \frac{5 + 1}{9 - 1} [/tex]

Therefore, the slope of AC is 3/4.

As all point have same slope. They are collinear point.

Answer:

height = 10 inches

base = 6 inches

The height and base width of the triangle will be 4 inches and 10 inches, respectively.

Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,

A = (1/2) × h·b

The base of a triangle measures 6 inches less than its height. If the area of the triangle is 20 square inches. Then the equations are given as,

b = h - 6             ...1

20 = (1/2)bh

40 = bh             ...2

From equations 1 and 2, then we have

40 = (h - 6)h

40 = h² - 6h

h² - 6h - 40 = 0

h² - 10h + 4h - 40 = 0

h(h - 10) + 4(h - 10) = 0

(h - 10)(h + 4) = 0

h = 10, -4

The height can be negative, so neglect -4. Then the width of the triangle is given as,

b = 10 - 6

h = 4

The height and base width of the triangle will be 4 inches and 10 inches, respectively.

Answer:

-8

Step-by-step explanation:

First add together the x's.

2x + 1 - 5 = -20

Now add 1 and -5,

2x - 4 = -20

Add 4 to both sides,

2x - 4 + 4 = -20 + 4

2x = -16

Divide both sides by 2,

2x/2 = -16/2

x = -8

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Sample mean(x) = 23500

Sample standard deviation (sd) = 3900

Sample size (n) = 20

Population mean (m) = 20,000

Null hypothesis : m = 20000

H1: m > 20000

To obtain the z-score :

(population mean - sample mean) / (sample standard deviation /√sample size)

(x - m) / (sd/√n)

(23500 - 20000) / (3900 / √20)

3500 / (3900 /4.4721359)

3500 / 872.06651

= 4.0134

Get the P value to know if to reject or accept the null:

P(z > 4.0134) = 1 - P(z < 4.0134)

P(z < 4.0134) = 1

1 - P(z < 4.0134) = 1 - 1 =0

Since P value is < alpha, we reject the null.

Hence average is > 20000

Given

[tex]\sqrt{150}[/tex]

Answer:

Option (B)

Step-by-step explanation:

Given equation of the absolute function is,

y = |x|

When this function is reflected across the x-axis, new equation of the graph will be

y = -|x|

Now the image of the given function has been scaled vertically by a factor of 7,

Therefore, equation of the new graph will be,

y = -7|x|

Option (B) is the correct option.

Step-by-step explanation:

[tex] \frac{x}{8} = \frac{9}{24} [/tex]

Cross multiply

We have

24x = 72

Divide both sides by 24

That's

[tex] \frac{24x}{24} = \frac{72}{24} [/tex]

We have the answer as

3x² + 2x - 10

when x = - 1

Substitute the value of x into the expression

That's

3(-1)² + 2(-1) - 10

= 3 - 2 - 10

We have the answer as

When x = 0

That's

3(0) + 2(0) - 10

When x = 1

That's

3(1)² + 2(1) - 10

= 3 + 2 - 10

= 5 - 10

[tex] \sqrt{( - 9)} [/tex]

Using the imaginary rule

That's

[tex] \sqrt{ - 1} = i[/tex]

We have

[tex] \sqrt{9} \times i[/tex]

We have the final answer as

[tex] \frac{1}{x} [/tex]

when x = 0

We have

[tex] \frac{1}{0} = 0[/tex]

when x = 1

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

when x = 2

We have

Answer:

[tex] x = 3 [/tex]

Step-by-step explanation:

From the figure given, we have points A,B, and C, that are collinear. Therefore, according to the segment addition postulate, [tex] AB + BC = AC [/tex].

We are given that:

AB = 9x + 7

BC = -5x + 20

AC = 39

An equation that can be used to solve for x would be:

[tex] (9x + 7) + (-5x + 20) = 39 [/tex]

Solve for x

[tex] 9x + 7 - 5x + 20 = 39 [/tex]

[tex] 9x - 5x + 7 + 20 = 39 [/tex]

[tex] 4x + 27 = 39 [/tex]

Subtract 27 from both sides

[tex] 4x + 27 -27 = 39 - 27 [/tex]

[tex] 4x = 12 [/tex]

Divide both sides by 4

[tex] \frac{4x}{4} = \frac{12}{4} [/tex]

[tex] x = 3 [/tex]

[tex] 2\sqrt{34} + 6 units [/tex]

Step-by-step explanation:

The perimeter of the polygon shown = AC + BC + AB

Using distance formula, calculate the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], calculate AC, BC, and AB.

The coordinates of the points are as follows,

A(3, 5),

B(0, 0)

C(6, 0)

Find AB:

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Where,

A(3, 5) => (x1, y1)

B(0, 0) => (x2, y2)

[tex] AB = \sqrt{(0 - 3)^2 + (0 - 5)^2} [/tex]

[tex] AB = \sqrt{(-3)^2 + (-5)^2} = \sqrt{9 + 25} = \sqrt{34} [/tex]

[tex] AB = \sqrt{34} units [/tex]

Find BC:

BC is easy to determine from the graph directly. The distance from point B to C, is 6 units.

Find AC:

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Where,

A(3, 5) => (x1, y1)

C(6, 0) => (x2, y2)

[tex] AC = \sqrt{(6 - 3)^2 + (0 - 5)^2} [/tex]

[tex] AB = \sqrt{(3)^2 + (-5)^2} = \sqrt{9 + 25} = \sqrt{34} [/tex]

[tex] AC = \sqrt{34} units [/tex]

Perimeter of the polygon = [tex] \sqrt{34} + 6 + \sqrt{34} [/tex]

[tex] = (\sqrt{34} + \sqrt{34}) + 6 [/tex]

[tex] = 2\sqrt{34} + 6 [/tex]

Answer: Margo does 48 activities in 4 weeks.

Step-by-step explanation:

In the calendar,

Red dots represent homework, yellow dots represent work, and green dots represent practice.

On a typical week , she uses 5 red dots, 3 yellow dots, and 4 green dots.

That means , total activity he does in a week = 5+3+4=12

Then, total activities in 4 weeks = 4 x 12 = 48

Hence, Margo does 48 activities in 4 weeks.
