Solve for h.
15.3 + 1 h =1.3- 1 h
Answer:
-7 = h
Step-by-step explanation:
15.3 + 1h = 1.3 - 1h
+1h +1h
15.3 + 2h = 1.3
Remember what you do to one side you MUST do to the other.
15.3 + 2h = 1.3
-15.3 -15.3
2h = -14
Now to isolate the variable you divide both sides by 2 to get, h = -7
Hope that helps and have a great day!
Hey there!☺
\(Answer:\boxed{h=-7}\)
\(Explanation:\)
\(15.3+1h=1.3-1h\)
In our first step, we will simplify both sides in the equation:
\(15.3+h=1.3+-h\\h+15.3=-h+1.3\)
Now add h to both sides:
\(h+15.3+h=-h+1.3+h\\2h+15.3=1.3\)
In step 3, divide both sides by 2:
\(\frac{2h}{2}=\frac{-14}{2}\)
Simplify -14/2:
\(\frac{-14}{2}=-7\\ h=-7\)
h=-7 is your answer.
Hope this helps!☺

Are the experimental probabilities after 300 trials closer to the theoretical probabilities?
After 300 trials, the experimental probabilities may not align perfectly with the theoretical probabilities. However, with more trials, the experimental probabilities tend to converge towards the theoretical probabilities for closer alignment.
To examine whether experimental probabilities after 300 trials align closely with theoretical probabilities, let's consider an example of flipping a fair coin.
Theoretical probability: When flipping a fair coin, the theoretical probability of obtaining heads or tails is 0.5 each. This assumes that the coin is unbiased and has an equal chance of landing on either side.
Experimental probability: After conducting 300 trials of flipping the coin, we record the outcomes and calculate the experimental probabilities. Let's assume that heads occurred 160 times and tails occurred 140 times.
Experimental probability of heads: 160/300 = 0.5333
Experimental probability of tails: 140/300 = 0.4667
Comparing the experimental probabilities to the theoretical probabilities, we can observe that the experimental probability of heads is slightly higher than the theoretical probability, while the experimental probability of tails is slightly lower.
In this particular example, the experimental probabilities after 300 trials do not align perfectly with the theoretical probabilities. However, it is important to note that these differences can be attributed to sampling variability, as the experimental outcomes are subject to random fluctuations.
To draw a more definitive conclusion about the alignment between experimental and theoretical probabilities, a larger number of trials would need to be conducted. As the number of trials increases, the experimental probabilities tend to converge towards the theoretical probabilities, providing a closer alignment between the two.

Answer:

Step-by-step explanation:
Differentiation is an algebraic process that finds the slope of a curve. At a point, the slope of a curve is the same as the slope of the tangent line to the curve at that point. Therefore, to find the slope of the line tangent to the given function, differentiate the given function.
Given function:
\(y=x^2\ln(2x)\)
Differentiate the given function using the product rule.
\(\boxed{\begin{minipage}{5.5 cm}\underline{Product Rule for Differentiation}\\\\If $y=uv$ then:\\\\$\dfrac{\text{d}y}{\text{d}x}=u\dfrac{\text{d}v}{\text{d}x}+v\dfrac{\text{d}u}{\text{d}x}$\\\end{minipage}}\)
\(\textsf{Let\;$u=x^2}\)\(\textsf{Let\;$u=x^2$}\implies \dfrac{\text{d}u}{\text{d}x}=2x\)
\(\textsf{Let\;$v=\ln(2x)$}\implies \dfrac{\text{d}v}{\text{d}x}=\dfrac{2}{2x}=\dfrac{1}{x}\)
Input the values into the product rule to differentiate the function:
\(\begin{aligned}\dfrac{\text{d}y}{\text{d}x}&=u\dfrac{\text{d}v}{\text{d}x}+v\dfrac{\text{d}u}{\text{d}x}\\\\&=x^2 \cdot \dfrac{1}{x}+\ln(2x) \cdot 2x\\\\&=x+2x\ln(2x)\end{aligned}\)
To find the slope of the tangent line at x = e²/2, substitute x = e²/2 into the differentiated function:
\(\begin{aligned}x=\dfrac{e^2}{2}\implies \dfrac{\text{d}y}{\text{d}x}&=\dfrac{e^2}{2}+2\left(\dfrac{e^2}{2}\right)\ln\left(2 \cdot \dfrac{e^2}{2}\right)\\\\&=\dfrac{e^2}{2}+e^2\ln\left(e^2\right)\\\\&=\dfrac{e^2}{2}+2e^2\\\\&=\dfrac{5e^2}{2}\end{aligned}\)
Therefore, the slope of the line tangent to the graph of y = x²ln(2x) at the point where x = e²/2 is:
\(\boxed{\dfrac{5e^2}{2}}\)

The answers to the box plot are given as follow;
1) the highest level of snow fall was 50inches. This is the maximum value on the plot
2) The data is most concentrated in the 3rd quarter. More cities has snow fall closer to 40 inches than to 13 inches.
3) the data is most spread all over the 4th quarter.
1) As per the data depicted in a box plot, it can be inferred that no urban center witnesses snowfall exceeding 50 inches.
2) The highest point on this chart supports this observation.
Furthermore, an overwhelming number of cities seem to report moderate levels of snowfall between 13-40 inches as indicated by most of these values lying within that particular section.
To buttress my argument further, I would note how close to its top edge is located the median line for this section. It is apparent that the data exhibits the highest degree of variability during the final quarter, signifying the top 25% of values.
The elongated vertical line extending from the upper end of the box up to the maximum value, which reaches 50 inches, is considerably lengthier than its counterpart at the bottom concluding with a minimum value of 5 inches.
This suggests that there is a greater disparity among snowfall measurements among cities receiving copious amounts.

2 3/4 of 500grams in step by step calculator
Answer:
To calculate 2 3/4 of 500 grams, follow these steps:
1. Convert the mixed number to an improper fraction:
2 3/4 = (2 x 4 + 3)/4 = 11/4
2. Multiply the improper fraction by 500:
11/4 x 500 = (11 x 500)/4 = 2,750/4
3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:
2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2
Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

I bought a pie. It cost somewhere between £1.30 and £2.99. I gave a 24% tip, and the total price was still an exact number of a pence. When I paid with a £5 note I received five coins in my change (the fewest I could have been given for that amount). What were the two possible amounts of change I could have been given?
Answer:
the two possible amounts of change are £3.01 and 39p.
Step-by-step explanation:
Let's start by finding the possible prices for the pie after the 24% tip has been added. We know that the total price must be an exact number of pence, which means that the price before the tip must have been a multiple of 25 (since there are 100 pence in a pound).
The possible prices before the tip, between £1.30 and £2.99, are:
£1.30 = 130p
£1.31 = 131p
...
£2.98 = 298p
£2.99 = 299p
To find the prices after the 24% tip, we multiply each of these values by 1.24:
130p * 1.24 = 161.2p = £1.612 = £1.61 (rounded to 2 decimal places)
131p * 1.24 = 162.44p = £1.6244 = £1.62
...
298p * 1.24 = 369.52p = £3.6952 = £3.70
299p * 1.24 = 370.76p = £3.7076 = £3.71
So the possible prices for the pie after the 24% tip are between £1.61 and £3.71.
Next, we need to find the possible amounts of change that would result from paying with a £5 note and receiving the fewest possible coins. We can do this by subtracting the total cost of the pie from £5 and seeing which combinations of coins add up to that amount.
Let's start with the lowest possible price for the pie, £1.61. If we add 24% to that, the total cost is £1.99 (rounded to 2 decimal places), which means our change is £3.01. The fewest possible coins we could receive for that amount are:
£2 coin
£1 coin
1p coin
So the first possible combination of change is:
£2 + £1 + 1p = £3.01
Now let's try the highest possible price for the pie, £3.71. If we add 24% to that, the total cost is £4.61, which means our change is 39p. The fewest possible coins we could receive for that amount are:
20p coin
10p coin
5p coin
2p coin
2p coin
So the second possible combination of change is:
20p + 10p + 5p + 2p + 2p = 39p
Therefore, the two possible amounts of change are £3.01 and 39p.
