If the measure of <2 is 5 less than 4 times the measure of <1. The measure of angle <1 is 37 degrees, and the measure of angle <2 is   143 degrees. The measure of angle <3 is 55 degrees.

Let's call the measure of angle <1 "x".

From the problem, we know that:

4 times the measure of angle <1 is equal to the measure of angle <2 plus 5:

4x = measure of angle <2 + 5

So the measure of angle <2 is 4x - 5.

Next, we know that the measures of all angles in a triangle must add up to 180 degrees.

Therefore, we have:

x + (4x - 5) + measure of angle <3 = 180

Expanding and simplifying:

5x - 5 + measure of angle <3 = 180

5x + measure of angle <3 = 185

5x = 185

Finally, solving for x:

x = 37

So the measure of angle <1 is 37 degrees, and the measure of angle <2 is 4 * 37 - 5 = 143 degrees. The measure of angle <3 is 185 - 5x = 185 - 5 * 37 = 55 degrees.

Answer: $135

Step-by-step explanation:

We have the ratio 1 : 3.

Kim gets $90 more than Jake.

So 1 : 3 can also be written as x : x+90

If x * 3 equals x+90, we can create the equation 3x=x+90. Solving this results in x being equal to 45

The distance between these two points (2,0) and (2,−5) is 5 unit.

The distance between two points is the length of the line segment connecting the two points on the plane. The formula for finding the distance between two points is usually d=√((x2 – x1)² + (y2 – y1)²). This formula is used to find the distance between any two points on the coordinate or x-y plane.

d=√((2 – 2)² + (-5 – 0)²)

d = √(0+25)

d = 5 unit

Step-by-step explanation:

Since the side lengths are proportional, the ratio of the width to length in the old phone will be equal to the ratio of the width to length in the new phone. That is:

(width of old phone) / (length of old phone) = (width of new phone) / (length of new phone)

We know the length of the old phone is 1.41.4 inches, and the width is 2.82.8 inches, so we can use that information to solve for the width of the new phone:

(2.82.8 inches) / (1.41.4 inches) = (width of new phone) / (1.611.61 inches)

Cross multiplying, we get:

(width of new phone) = (2.82.8 inches) * (1.611.61 inches) / (1.41.4 inches)

Using a calculator, we can find that the width of the new phone is approximately 3.23.2 inches.

Using the gradient of the curve given, the value of a is 6

The stationary point of a curve is a point where the slope of the curve is equal to zero. So, to find the value of a, we need to set the derivative of the curve equal to zero and solve for x.

dy/dx = 2(x + 3)^(1/2) - x

Setting this equal to zero, we have:

2(x + 3)^(1/2) - x = 0

Expanding the square root and rearranging, we get:

x = 2(x + 3)^(1/2)

Squaring both sides of the equation, we have:

x^2 = 4(x + 3)

Expanding the right side and rearranging, we have:

x^2 - 4x - 12 = 0

Using the quadratic formula, we can find the values of x that satisfy this equation:

x = [-(-4) ± √((-4)^2 - 4(1)(-12))] / 2(1)

x = [4 ± √(16 + 48)] / 2

x = [4 ± √64] / 2

x = [4 ± 8] / 2

So, the two possible values of x are:

x = 6, x = -2

Since we are looking for a positive value of x, the only solution that works is x = 6.

Therefore, the value of a is equal to 6.

If one her 4 numbers come up, she wins $40 (and gets to keep her bet!). Alyssa can expect to lose 47 cents per bet over the long run.

The expected value of a game is the average amount that a player can expect to win or lose per bet, taking into account both the probabilities and the payouts of each possible outcome. To find the expected value, we multiply the probability of each outcome by the amount won or lost for that outcome, and then sum up these products.

In this case, Alyssa bets $5 on a block of 4 numbers, which gives her a probability of winning of 4/38, or approximately 0.1053. If one of her 4 numbers comes up, she wins $40, for a net gain of $35 (since she gets to keep her $5 bet as well). If none of her 4 numbers comes up, she loses her $5 bet.

Therefore, the expected value for each bet is:

(0.1053 × $35) + (0.8947 × -$5) = -$0.47

The interquartile range (IQR) in descriptive statistics is a measurement of statistical dispersion, or the spread of the data. The IQR is also known as the middle 50%, the fourth spread, or the H-spread. The difference between the data's 75th and 25th percentiles is how it is defined.

The median (middle value) of the lower half and upper half of the data should be found first in order to determine the interquartile range (IQR). The quartile 1 (Q1) and quartile 3 values are these (Q3). The IQR is the difference between Q3 and Q1.

From the given stem-and-leaf plot, we can see that the lowest score is 5, and the highest score is 23. Therefore, the range of the data is:

Range = highest value - lowest value = 23 - 5 = 18

We also need to find the quartiles to calculate the IQR. The median (Q2) of the data is 18, which is the value that separates the lower 50% of the scores from the upper 50%. To find Q1 and Q3, we can split the lower and upper halves of the data, respectively, and find their medians.

John has average 2 books and Peter has 4 books. Together, they have 6 books.

John has 2 books

Peter has twice books more than John = 2 * 2 = 4 books

Total books they have together = 2 + 4 = 6 books

John has 2 books, so Peter has twice books more than John. This means that Peter has 2 * 2 = 4 books. Together, John and Peter have 2 + 4 = 6 books. John’s books are the starting point of the problem, so it is important to keep track of John’s books. Since Peter has twice books more than John, we can calculate the number of books that Peter has by multiplying the number of books that John has by two. Once we have calculated the number of books that Peter has, we can add the number of books that John has to the number of books that Peter has and get the total number of books that they have together. In this example, the total number of books that John and Peter have together is 6. This can be arrived at by adding the number of books that John has (2) to the number of books that Peter has (4).

The actual amount of sale for each bake is $214. As Miguel said it is $215 which is very close to the actual amount, it is reasonable.

To determine if Miguel's estimate of $215 per bake sale is reasonable, we can start by calculating the average amount of money the scout troop made per bake sale. We do this by dividing the total amount they earned by the number of sales they had, as follows:

Total amount earned = $1,498

Number of bake sales = 7

Average amount earned per bake sale = Total amount earned ÷ Number of bake sales

= $1,498 ÷ 7

= $214

This calculation shows that the average amount the scout troop made per bake sale was $214. This means that if they had charged a consistent price for all of their baked goods at each sale, they would have made an average of $214 per sale.

Now, we can compare this average to Miguel's estimate of $215 per bake sale. Since his estimate is very close to the actual average, we can conclude that it is reasonable.

It is possible that the scout troop charged slightly different prices for their baked goods at each sale, which could explain the small discrepancy between the actual average and Miguel's estimate. However, given that the difference between the two values is only $1, it is likely that Miguel's estimate is a good approximation of the actual amount.

Moreover, it is reasonable to assume that the scout troop earned the same amount at each bake sale, especially if they had a set price for their baked goods.

If they had charged different prices at each sale, it would have been more difficult to estimate the average amount they earned per sale, and it would have been less likely that Miguel's estimate of $215 per bake sale would have been close to the actual average.

Therefore, based on the calculation and the context of the problem, we can conclude that Miguel's estimate of $215 per bake sale is reasonable.
