To find the change in temperature during a 1.5-hour period after a storm began, it would be necessary to take two temperature readings, one before the storm began and one after the storm ended. By subtracting the two readings, the change in temperature can be determined. For example, if the temperature before the storm began was 75.4°F and the temperature after the storm ended was 79.2°F, the change in temperature would be 3.8°F.

there are four boys to every seven girls in an introductory geology course. if there are 374 students enrolled in the course, how many are boys?
There are 172 boys in the introductory geology course.
The ratio of boys to girls is 4:5. We can know that the number of boys in the class is four multiplied by the common value that the ratio is based on.
We can call this usual value x and say that the number of boys in the class is 4x. Applying the same logic to the girls, we can say that there are 5x girls in the class. Hence, a total of 9x children. We divide the total value by 9 to get x, which equals 43.
We can then calculate the number of boys by calculating 4x, which equals 172.

What are quadratic Equation ?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.
When a quadratic equation is solved, the two values of x that result are known as the roots of the equation. The zeros in the equation are another name for these quadratic equation roots. For instance, x = -1 and x = 4 are the roots of the equation x² - 3x - 4 = 0 since they each fulfill it.
The easiest method for locating a quadratic equation's roots is the quadratic formula. There are some quadratic equations that are difficult to factor, and in these cases we can quickly discover the roots by using the quadratic formula. The quadratic equation's roots also aid in determining the quadratic equation's sum of roots and product of roots. The quadratic formula's two roots are shown as a single statement.
The equation are :
x² - 9 = 0 ⇒ (x-3)(x+3) = 0 ,

the zeros of this polynomial are x = 1, x = 4, x = -2. Explain his error. (DOK3)
Answer:
one of the zeros is x = 0 and not x = 1
Step-by-step explanation:
Zeros are found by setting each of the factors to 0 and solving for x
Factors are x, x -4, x + 2
Set each of them to 0:
x =0
x + 2 = 0 ==> x = -2
x -4 = 0 ==> x = 4
So one of the zeros is x = 0 and not x = 1
If you roll the cube 30 times, how many 3's?
if you could show work that would be great ((:
The expected number of 3's would be 5.
What is probability?
Probability is a field of mathematics that calculates the likelihood of an experiment occurring. We can know everything from the chance of getting heads or tails in a coin to the possibility of inaccuracy in study by using probability.
The probability of rolling a 3 on a single roll of a fair six-sided die is 1/6, since there is one favorable outcome (rolling a 3) out of a total of six possible outcomes (rolling a 1, 2, 3, 4, 5, or 6).
However, it's important to keep in mind that the actual number of 3's obtained in 30 rolls of a die can vary, as the outcome of each roll is inherently random.
The expected value provides us with a guide for what to expect on average, but in any given sequence of rolls, the actual number of 3's may be higher or lower.
So, if you roll the cube 30 times, the expected number of 3's would be 30 * 1/6 = 5.

Consider the points A = (0, 0), B = (1, 0) and C = (0, 1). Now choose a random point (X, Y ) uniformly from the union of the line segments AB and AC. Find Cov(X, Y )
The answer is cov(x,y) = 0.059, if we choose a random point (X, Y ) uniformly from the union of the line segments AB and AC.
As given, A = (0, 0) ,B = (1, 0) and C = (0, 1)
and we have the select x and y from line segment AB and AC respectively.
So, x can be 1.0, 0.8, 0.6, 0.4, 0.2
and y can be 1.0, 0.8, 0.6, 0.4, 0.2
Now we have to find,
cov(x,y) = ∑(Xi - μ) (Yj - v) / n
where,
Cov(X, Y) represents the covariance of variables X and Y.Σ represents the sum of other parts of the formula.(Xi) represents all values of the X-variable.µ represents the average value of the X-variable.Yj represents all values of the Y-variable.v represents the average value of the Y-variable.Σ represents the sum of the values for both (Xi-µ) and (Yj-v).n represents the total number of data points across both variables.Now µ = 1.0 + 0.8 + 0.6 + 0.4 + 0.2 + 0.0 ÷ 6
µ = 3 ÷ 6
µ = 1/2 = 0.5
Now v = 1.0 + 0.8 + 0.6 + 0.4 + 0.2 + 0.0 ÷ 6
v = 3 ÷ 6
v = 1/2 = 0.5
Now, we have to find
(Xi - µ) = (1.0 - 0.5), (0. 8- 0.5), (0.6 - 0.5), (0.4 - 0.5), (0.2 - 0.5),
(0.0 - 0.5)
(Xi - µ) = 0.5, 0.3, 0.1, (-0.1), (-0.3), (-0.5)
(Yj - v) = (1.0 - 0.5), (0. 8- 0.5), (0.6 - 0.5), (0.4 - 0.5), (0.2 - 0.5),
(0.0 - 0.5)
(Yj - v) = 0.5, 0.3, 0.1, (-0.1), (-0.3), (-0.5)
Now calculate (Xi - μ) (Yj - v): multiply them with their respective one
(Xi - μ) (Yj - v) = (0.5×0.5), (0.3×0.3), (0.1×o.1), (-0.1)(-0.1), (-0.3)(-0.3),
(-0.5)(0.5)
therefore,
∑(Xi - μ) (Yj - v) = (0.25+ 0.09 + 0.01 + 0.01 + 0.09 + 0.25)
∑(Xi - μ) (Yj - v) =0.35
Now, cov(x,y) = ∑(Xi - μ) (Yj - v) / n
cov(x,y) = 0.35 / 6
cov(x,y) = 0.059

20% of the population were teenagers.
The number of teens at that time was:
= 800/100*20
= 8*20
= 160
Therefore, using percentages, we can deduce that 160 of the 800 attendees at the football and math conference were teenagers, or 20% of the total.

for the stem and leaf plot created in question 9 are there any extreme values? if so, what are they?
As a result, the extreme stem values may contain fewer rows than the other stem values. In our graph, the extreme stem values are 1 and 4, and they both have fewer rows than the middle values (2 and 3).
The shape and spread of a continuous data distribution are depicted by stem and leaf plots. These graphs are similar to histograms, but instead of bars, they display numbers.
Statistical software packages use an algorithm to improve our ability to read stem and leaf plots by displaying multiple rows of each stem value based on the properties of the data, as shown in the body fat percentage graph. There are two ones, five twos, five threes, and four fours.
The graph divides stem values into five rows for the body fat percentage data. Each row only has two leaf values (e.g., 0 and 1, 2 and 3, etc.) The leaf values terminate at the dataset's minimum and maximum values.

What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q, meaning that each term is obtained by the multiplication of the previous term by the common ratio q.
The explicit formula of a geometric sequence is given by:
[tex]f(n) = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
For the recursive formula, we have that:
f(n) = q x f(n - 1).

Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
Cosine of ∠U is 28/53 in proper fraction, 28/53 in improper fraction, 0.52609 in whole number.
The cosine of an angle in a right triangle can be found using the ratio of the adjacent side to the hypotenuse. In this triangle, the adjacent side to ∠U is 28 and the hypotenuse is 53.
cos(∠U) = adjacent side ÷ hypotenuse = 28 ÷ 53 = 28/53
So, the cosine of ∠U is 28/53, written as a proper fraction.
Now let's convert cosine of ∠U is 28/53 in improper fraction:
The cosine of ∠U, which is 28/53, can be expressed as an improper fraction by dividing both the numerator and denominator by their greatest common factor.
gcd(28, 53) = 1, so the fraction cannot be further simplified.
Therefore, the cosine of ∠U, expressed as an improper fraction, is 28/53.
Now let's convert cosine of ∠U is 28/53 in whole number:
The cosine of ∠U, which is 28/53, can be expressed as a whole number by dividing the numerator by the denominator.
28 ÷ 53 = 0.526087
So, the cosine of ∠U expressed as a whole number is approximately 0.52609
