The correct label for the population would be: 1-100 as per the given scenario.

In statistics, a population refers to the entire group of individuals, objects, or measurements that the researcher is interested in studying.

In this scenario, the population refers to the entire group of items or people that the farmer is interested in studying.

In this case, the population is the total number of ears of corn produced by all 100 seeds sown by the farmer.

As a result, the population's correct label would be: 1-100. Because the farmer is interested in the yield of all 100 seeds, the population includes all possible outcomes of the experiment, ranging from one to one hundred ears of corn.

Option A, B, and C do not include all possible outcomes, whereas option D includes the number 0, which is not an option in this scenario.

Thus, the answer is 1-100.

x = 4 2/3

Step-by-step explanation:

x = 5 - 1/3

x = 4 2/3

Answer:

x = [tex]\frac{14}{3}[/tex]

Step-by-step explanation:

Subtract [tex]\frac{1}{3}[/tex] from both sides

x + [tex]\frac{1}{3}[/tex] - [tex]\frac{1}{3}[/tex] = 5 - [tex]\frac{1}{3}[/tex]

x = [tex]\frac{14}{3}[/tex] or 4 [tex]\frac{2}{3}[/tex]

Answer:

False

Step-by-step explanation:

_7/10 does not equal -4/5

Answer: No.

Step-by-step explanation: The left side, -0.7 doesn't equal the right side, -0.8, so it is false.

To find equivalent fractions, multiply the the numerator and denominator by the same whole number.

[tex]-\frac{7}{10}\times\frac{2}{2} =-\frac{14}{20}[/tex]

[tex]-\frac{7}{10}\times\frac{3}{3} =-\frac{21}{30}[/tex]

[tex]-\frac{7}{10}\times\frac{4}{4} =-\frac{28}{40}[/tex]

And so on...

[tex]-\frac{4}{5}\times\frac{2}{2} =-\frac{8}{10}[/tex]

[tex]-\frac{4}{5}\times\frac{3}{3} =-\frac{12}{18}[/tex]

[tex]-\frac{4}{5}\times\frac{4}{4} =-\frac{16}{20}[/tex]

And so on...

If we keep doing this, they won't equal each other.

So no, they're not equivalent.

Answer:

Jessica's trains travels at a faster speed

Step-by-step explanation:

From the question,

Using the graph,

The total distance distance traveled by Khalid after 2 hours is

d = 280 mi.

S = d/t....................... Equation 1

Where S = Khalid's speed, d = Khalid's distance, t = time.

S = 280/2

S = 140 mph.

From the euqation,

The total distance traveled by Jessica after 2 hours is

y = 150×2

y = 300 mi.

Also Using

S' = d'/t

Where S' = Jessica's speed, d' = Jessica's distance

S' = 300/2

S' = 150 mph.

From the above, Jessica's trains travels at a faster speed

Answer:

D. BA = 8, AC = 8√3

Step-by-step explanation:

First, because this is a right triangle, refer to the trigonometric ratios:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

BA is the opposite side to the angle measure given, ∠C—which is 30°—and we have the measure of BC. BC is the hypotenuse, as it is across from the right angle of the right triangle. So we can use sine:

sine = opposite side/hypotenuse

sin(30) = BA/16

sin(30) / 1 = BA / 16

Cross multiply:

BA = sin(30) (16)

BA = 8

AC is the adjacent side to the angle measure given, ∠C—which is 30°—and we have the measure of BC. BC is the hypotenuse, as it is across from the right angle of the right triangle. So we can use cosine:

cosine = adjacent side/hypotenuse

cos(30) = AC/16

cos(30) / 1 = AC / 16

Cross multiply:

AC = cos(30) (16)

AC = 8√3

You can check by using the Pythagorean Theorem:

a² + b² = c²

8² + (8√3)² = 16²

64 + 192 = 256

256 = 256

Answer:

Step-by-step explanation:

We can imagine the rectangle, when cut diagonally it forms a Right angled Triangle

Using this we can find the diagonal i.e hypotenuse.

From the question we know that,

Length = 120 metres

Width = 90 metres

So we can find the diagonal by keeping it as x using the pythogorean theorem.

[tex] {120}^{2} + {90}^{2} = {x}^{2} \\ 14400 + 8100 = {x}^{2} \\ 22500 = {x}^{2} \\ x = \sqrt{22500} \\ x = 150[/tex]

Answer:

y = 42x + 75

Step-by-step explanation:

Using the equation of a line in the form

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁) = m where m is the slope of the line

Let x be the number of hours the electrician works in a single visit, and let y be the total amount, in dollars, that the electrician charged for the visit.

Since the electrician worked 2.5 hours and charged $180 for the first visit. The second time he worked 4 hours and charged $243. where x₁ = 2.5 hours, y₁ = $ 180, x₂ = 4 hours and y₂ = $ 243

We find the slope of the line, m

m = (243 - 180)/(4 - 2.5) = (243 - 180)/(4 - 2.5) = 63/1.5 = 42

Since m = (y - y₁)/(x - x₁) ,

42 = (y - 180)/(x - 2.5)

cross-multiplying, we have

42(x - 2.5) = (y - 180)

expanding the bracket, we have

42x - 105 = y - 180

adding 180 to both sides, we have

42x - 105 + 180 = y - 180 + 180

42x + 75 = y

y = 42x + 75

The linear equation that relates the total cost to the time worked is:

[tex]y = 42x + 75[/tex]

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

In this problem, the function has two points: (2.5, 180) and (4, 243).

The slope is given by change in y divided by change in x, hence:

[tex]m = \frac{243 - 180}{4 - 2.5} = 42[/tex]

Then:

[tex]y = 42x + b[/tex]

Considering point (2.5, 180), we have that when x = 2.5, y = 180, which is used to find b.

[tex]y = 42x + b[/tex]

[tex]180 = 42(2.5) + b[/tex]

[tex]b = 75[/tex]

Hence, the function is:

[tex]y = 42x + 75[/tex]

Answer:

Yes

Step-by-step explanation:

Congruence means two objects (whether two dimensional or three dimensional) are identical in size and shape. Everything about them -- their angles, lengths of sides, overall dimensions -- are identical. Similar means being the same shape. Two congruent figures must be the same shape, so they are similar.
