I would really like an explanation..

Answer:

80%

Step-by-step explanation:

132÷165=0.8

0.8×100=80%

80% of the plants in the school garden will flower in spring. The correct answer is [tex]$\boxed{80\%}$[/tex].

To find the percentage of plants that will flower in spring, we use the formula for percentage, which is:

 [tex]\[ \text{Percentage} = \left( \frac{\text{Number of plants flowering in spring}}{\text{Total number of plants}} \right) \times 100\% \][/tex]

Given that there are 165 different plants in total and 132 of these will flower in spring, we can substitute these values into the formula:

[tex]\[ \text{Percentage} = \left( \frac{132}{165} \right) \times 100\% \][/tex]

Now, we simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 33:

[tex]\[ \text{Percentage} = \left( \frac{132 \div 33}{165 \div 33} \right) \times 100\% \] \[ \text{Percentage} = \left( \frac{4}{5} \right) \times 100\% \] \[ \text{Percentage} = 0.8 \times 100\% \] \[ \text{Percentage} = 80\% \][/tex]

To calculate the amount after 2 years, use the formula for continuous compound interest. To find how long it will take for the amount to be $10,000, rearrange the formula and solve for t.

To calculate the amount after 2 years, we can use the formula for continuous compound interest: A = P * e^(rt), where A is the amount, P is the principal, e is Euler's number approximately equal to 2.71828, r is the interest rate, and t is the time in years.

Using the given values, we have A = 5900 * e^(0.06 * 2).

Using a calculator, we can find that A is approximately $6488.85.

To find how long it will take for the amount to be $10,000, we can rearrange the formula and solve for t. In this case, we have 10000 = 5900 * e^(0.06t).

Dividing both sides by 5900 and taking the natural logarithm of both sides, we get ln(10000/5900) = 0.06t.

Using a calculator, we find that t is approximately 3.41 years.

Answer:

1. correlation

2. causation

3. causation

4. correlation

5. correlation (depends on the price of the car sold)

6. correlation

7. correlation (it technically is, but your teacher may be looking for causation)

8. correlation

Step-by-step explanation:

Correlation indicates how variables fluctuate together, but causation is a cause-and-effect relationship between variables. Real-world examples often illustrate how a third variable can account for a correlation, emphasizing that correlation does not imply causation.

The terms correlation and causation are often used in research to describe relationships between variables. Correlation refers to a statistical measure that indicates the extent to which two or more variables fluctuate together. A positive correlation means that as one variable increases, the other tends to increase as well, and vice versa. Meanwhile, causation, or causality, implies that one event is the result of the occurrence of the other event; there is a cause-and-effect relationship. For causation to be established, certain conditions must be met: the cause must precede the effect in time, the relationship must be plausible, and there must be evidence that the relationship is nonspurious, meaning it is not due to some third, confounding variable.

Real-world examples often show that discerning causation from correlation can be tricky. For instance, higher ice cream sales are correlated with increased drowning deaths, but the common cause is the hot summer season, rather than ice cream sales directly causing drowning. Similarly, the presence of more firefighters at a fire correlates with more fire damage, but the actual cause is that larger fires require more firefighters and inherently cause more damage. In both instances, a third variable explains the correlation without a causal relationship between the primary two variables discussed.

To summarize, while correlation and causation both deal with relationships between variables, they are not the same. Correlation does not imply causation, and careful consideration must be given to establish a true cause-and-effect relationship, ensuring that logical time ordering, mechanism, and nonspuriousness are effectively demonstrated.

Answer:

-35-42j

Step-by-step explanation:

666/2= 333    Divide in half.

333 + 84 = 417  Add 84 to bench since its $84 more.

666 - 417 = 249 Subtract to get value of table.

Therefore, the table costs $249 and the bench costs $417.

Answer:

375

Step-by-step explanation

Because u take the equation and plug in each of the values getting you G+B=666 and then you know that the Garden Table is less than the bench so u plug that in to get B-84+B=666 and then you combine like terms and get 2b-84=666 then you can solve the equations by first adding to even the equation 2b=750 then dividing 2 by 750 to get b=375.

Final answer:

To find the designated sum in an arithmetic series, use the formula (n/2)(a_1 + a_n), where n represents the number of terms, a_1 is the first term, and a_n is the last term.

Explanation:

How to Find the Designated Sum in Arithmetic Series

An arithmetic series is a sequence of numbers in which the difference between consecutive terms is constant. To find the designated sum in an arithmetic series, you can use the formula:

S_n = (n/2)(a_1 + a_n)

Identify the first term (a_1), the number of terms (n), and the common difference (d) of the arithmetic series.

Use the formula a_n = a_1 + (n-1)d to find the value of the last term in the series (a_n).

Substitute the values of a_1, a_n, and n into the formula S_n = (n/2)(a_1 + a_n) to calculate the designated sum of the arithmetic series.

Answer:

6.25 %  of area of Large triangle =  area of smallest triangle

Step-by-step explanation:

Area of large triangle L = (1/2)*base*height

L = (1/2)*(44 m)* h

L = 22*h  square m.

2nd equilateral triangle area:  S =(1/2)*(22 m)*(0.5h)

S = 5.5*h sq. m.

3rd smallest equilateral triangle area : T = (1/2)*(11 m)*(0.25h)

T = 1.375*h sq. m

-----

Find percent P  where  T = P* L,     1.375*h = P * 22*h

P = 6.25%  = 0.0625

Answer:

r = 5 feet

Step-by-step explanation:

see attached for reference

recall that volume of a circular cone is given by

V = (1/3) πr²h, where

V = volume = given as 50π ft³

r = radius (we are asked to find this)

h = height of cone = given as 6 feet

Substituting the above known values into the equation:

V = (1/3) πr²h

50π = (1/3) π (r²)(6)

50π = π (r²)(2)  (divide both sides by 2)

25π = π r²   (divide both sides by π)

25 = r²

r = ±√25

r = ±5   (since radius cannot be negative, we select the positive value

r = 5 feet
