The change in temperature of the charcoal from 180°F to 60°F is equal to a decrease of approximately 2.2 degrees Celsius.

To convert Fahrenheit to Celsius, we can use the formula:

Celsius = (Fahrenheit - 32) × 5/9

We know that the initial temperature of the charcoal was 180°F, and it experienced a temperature drop of 120°F. To find the final temperature in Fahrenheit, we can subtract 120°F from 180°F:

Final temperature in Fahrenheit = 180°F - 120°F = 60°F

Now, we can convert the final temperature from Fahrenheit to Celsius using the formula above:

Celsius = (60°F - 32) × 5/9

Celsius = (28°F) × 5/9

Celsius = -2.2222...

Rounding the result to one decimal place, we get:

Celsius = -2.2 degrees Celsius (approx.)

It's worth noting that the Celsius scale is based on the metric system, which is the standard measurement system used in most countries worldwide. In contrast, the Fahrenheit scale is primarily used in the United States and a few other countries, making it less universal. Understanding how to convert between the two scales is crucial in various scientific, engineering, and technical fields.

Answer:

[tex]0.1212...=\dfrac{4}{33}[/tex]

Step-by-step explanation:

A repeating decimal is a decimal number with a digit (or group of digits) that repeats forever.

There are three ways to show a repeating decimal:

0.1212... is a repeating decimal as there are two duplicates of the repeating block of digits "12" followed by an ellipsis.

To express a repeating decimal as a rational number, begin by assigning the decimal to a variable:

[tex]x=0.1212...=0.\overline{12}[/tex]

Multiply both sides by 100:

[tex]\implies x \cdot 100=0.\overline{12}\cdot 100[/tex]

[tex]\implies 100x=12.\overline{12}[/tex]

Subtract the first equation from the second to eliminate the part after the decimal:

[tex]\begin{array}{crcr}& 100x & = & 12.\overline{12}\\- & x & = & 0.\overline{12}\\\cline{2-4} & 99x & = & 12\phantom{.12}\\\end{array}[/tex]

Divide both sides of the equation by 99:

[tex]\implies \dfrac{99x}{99}=\dfrac{12}{99}[/tex]

[tex]\implies x=\dfrac{12}{99}[/tex]

Reduce the fraction to is simplest form by dividing the numerator and denominator by 3:

[tex]\implies x=\dfrac{12 \div 3}{99 \div 3}=\dfrac{4}{33}[/tex]

The map that shows the picnic table in the correct location is illustrated below.

Firstly, we need to understand the concept of scale on a map. Maps are often drawn to scale, which means that the distances between different points on the map represent a proportional distance in real life. For instance, if one inch on the map equals one mile in real life, then two inches on the map would represent two miles in real life.

To do this, we need to locate the campsite on the map and measure out 1.5 miles along Path A. Once we have done this, we can mark this location on the map as the location of the picnic table.

However, we need to make sure that we are using a map that is drawn to scale. Otherwise, we might not be able to accurately measure the distance and locate the picnic table correctly.

Therefore, we need to examine the different maps that we have and find one that is drawn to scale. Once we have found a suitable map, we can measure out the distance from the campsite to the location of the table along Path A, and mark it on the map.

Finally, we can compare the location we have marked on the map with the location of the table as described in the problem. If they match up, we have found the correct location of the table on the map.

In Mathematics, the exterior angle theorem or postulate is a theorem which states that the measure of an exterior angle in a triangle is always equal in magnitude (size) to the sum of the measures of the two remote or opposite interior angles of that triangle.

By applying the exterior angle theorem, we can reasonably infer and logically deduce that the sum of the measure of the two interior remote or opposite angles in the triangle BHY is equal to the measure of angle x (∠NYB);

m∠BHY + m∠HBY = m∠NYB

(2x + 7)° + (8x - 18)° = (4x + 91)°

10x - 11 = 4x + 91

The sum of all the three angles of a triangle is 180°.

x + x + 26.35° = 180°

2x = 180° - 26.35°

x = 76.825°.

Therefore, ∠P will be equal to 76.825°.

Answer:

∠P = 76.825°

Step-by-step explanation:

If angles P and Q are congruent, then triangle PQR is an isosceles triangle where ∠P and ∠Q are the base angles and ∠R is the apex angle.

The interior angles of a triangle sum to 180°. Therefore:

⇒ ∠P + ∠Q + ∠R = 180°

As ∠P = ∠Q and ∠R = 26.35°, then:

⇒ ∠P + ∠P + 26.35° = 180°

⇒ 2∠P + 26.35° = 180°

⇒ 2∠P + 26.35° - 26.35° = 180° - 26.35°

⇒ 2∠P = 153.65°

⇒ 2∠P ÷ 2 = 153.65° ÷ 2

⇒ ∠P = 76.825°

Therefore, the measure of angle P is 76.825°.

a. The sample correlation between self-reported political orientation and support for the legalization of medical marijuana is r = -0.67. This negative correlation indicates that as political orientation becomes more conservative (higher score), support for the legalization of medical marijuana decreases (lower score). The correlation is moderate in size, which means that there is a meaningful relationship between these two variables.

b. The null hypothesis is that there is no correlation between self-reported political orientation and support for the legalization of medical marijuana in the population, symbolized as H0: ρ = 0. The alternative hypothesis is that there is a correlation in the population, symbolized as Ha: ρ ≠ 0.

c. The critical value for a two-tailed test with alpha level α = 0.05 and n = 30-2 = 28 degrees of freedom is ±2.048. The rejection regions are the two tails of the t-distribution with this critical value.

d. The appropriate t-test to answer this question is a two-tailed test of the population correlation coefficient using the formula: t = r√(n-2) / √(1-r^2). Plugging in the values from the sample, we get: t = -3.29.

e. We reject the null hypothesis because the calculated t-value (-3.29) falls outside the rejection region (±2.048). This means that the sample correlation is significantly different from 0, and we have evidence to support the alternative hypothesis that there is a correlation in the population. The p-value associated with the sample correlation is p < 0.01, which means that there is less than a 1% chance of obtaining a correlation as extreme as the one observed in the sample if the null hypothesis is true. This suggests strong evidence against the null hypothesis. If the null hypothesis were true, the sample correlation would be expected to be near 0, and it is very unlikely to obtain a correlation as strong as -0.67.
