The given problem can be exemplified in the following diagram:
We have that the angle theta is located at the vertex of a right triangle with an opposite side of 1 and the adjacent side of 3. We are asked to determine the value of the cosecant of the angle. Let's remember that the function cosecant is defined as:
\(\csc \theta=\frac{hypotenuse}{opposite}\)To determine the hypotenuse we will use the Pythagorean theorem. This is:
\(h^2=a^2+b^2\)Where:
\(\begin{gathered} h=\text{ hypotenuse} \\ a,b=\text{ sides} \end{gathered}\)Now we solve for the hypotenuse by taking the square root to both sides:
\(h=\sqrt[]{a^2+b^2}\)replacing the values:
\(h=\sqrt[]{(3)^2+(1)^2}\)Now we solve the square:
\(h=\sqrt[]{9+1}\)Solving the addition we get:
\(h=\sqrt[]{10}\)Now we replace in the definition for cosecant
\(\csc \theta=\frac{\sqrt[]{10}}{1}=\sqrt[]{10}\)Therefore, the value of the function is the square root of 10.
Dan was the team’s star batter. He had a batting average of 60%. If Dan had 30 hits last summer, how many at bats did he have?
Answer:
50 bats total
Step-by-step explanation:
To solve this problem, all one has to do is, set up a proportion, remember, a proportion is;
\(\frac{part}{whole} = \frac{percent}{100}\)
In this case;
\(\frac{hits}{total.bats} = \frac{percent}{100}\)
It is given that;
percent - 60%
hits - 30
Now substitute in the values and solve;
\(\frac{30}{total.bats} = \frac{60}{100}\)
Solve, first simplify;
\(\frac{30}{total.bats} = \frac{3}{5}\)
Now use cross products;
150 = 3(total_bats)
Inverse operations;
150 = 3(total_bats)
/3 /3
50 = total_bats
100 POINTS AND BRAINLIEST !!!!! (I need the answer ASAP) A school is planning to construct two rectangular play areas in the playground.

Describe how quadratics differ from functions that are not quadratics. Describe any symmetries that you see,asymptotes, the domain, range, how it is decreasing or increasing, concavity.
if we look at the different graphs shown for quadratic functions we can see that this type of function has symmetry along the vertical line formed at the vertex. Also, the domain usually integrates all the numbers along the x-axis, this means that the domain is all real numbers, however, the range is going to be different, this is going to depend on the concavity, there are two types of concavities for quadratic functions: when the function is concave up the graph is bending upwards, this means that the range will be the numbers greater than the vertex, this is because the graph won't take place at the y-axis for this numbers; when the function is concave down the graph is bending downwards and the range will be opposite as before, the range is going to be the numbers less than the vertex. Finally, another typical thing about this type of function is that the function might be decreasing or increasing depending on the concavity but when it reaches the vertex of the function the direction will change meaning that if it was decreasing, after the vertex it will start increasing, or if the function was increasing, after the vertex it will start decreasing.
\(undefined\)the probability of rolling an even number when an unfair die is rolled is about 0.65. which of the following is closest to the probability that an even number is rolled 15 or fewer times when the die is rolled 25 times total
The probability that an even number is rolled 15 or fewer times when the die is rolled 25 times total can be calculated using the binomial probability formula. In this case, the probability of success is rolling an even number (0.65) and the number of trials is 25.
Using the binomial probability formula, we can calculate the probability of getting 15 or fewer even numbers when the die is rolled 25 times as follows:
P (X <= 15) = P (X = 0) + P (X = 1) + P (X = 2) + ... + P (X = 15)
Where X is the number of even numbers rolled and P(X) is the probability of getting X even numbers.
Using the binomial probability formula:
P(X) = (25 choose X) * (0.65)^X * (0.35)^(25-X)
Plugging in the values, we get:
P(X <= 15) = (25 choose 0) * (0.65)^0 * (0.35)^25 + (25 choose 1) * (0.65)^1 * (0.35)^24 + (25 choose 2) * (0.65)^2 * (0.35)^23 + ... + (25 choose 15) * (0.65)^15 * (0.35)^10
After calculating all the values, we get that the probability of rolling an even number 15 or fewer times when the die is rolled 25 times is about 0.28.
Therefore, the closest answer choice to the probability that an even number is rolled 15 or fewer times when the die is rolled 25 times is 0.25.

Formula for the mass m = Dv and the mass of gasoline is 9520 gm. The formula for volume is v = m/D and the volume of the syrup is 52.63 cm³.
What is the meaning of mass?
A measure of the amount of matter contained in or constituting a physical body.
Given that, D = m/v
Multiply both sides by v
Dv = m
Rearrange the above equation:
m = Dv
Putting D = 0.680 gm/cm³ and v = 14000 cm³ in the above equation:
m = (0.680 gm/cm³) × (14000 cm³)
m = 9520 gm
Given that, D = m/v
Multiply both sides by v
Dv = m
Divide both sides by D
v = m/D
Putting D = 0.950 gm/cm³ and m = 50.0 gm in the above equation:
v = (50.0 gm) / (0.950 gm/cm³)
m = 52.63 cm³

Calculate the side lengths a and b to two decimal places
Answer:
E
Step-by-step explanation:
using the Sine rule in Δ ABC
\(\frac{a}{sinA}\) = \(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
where a is the side opposite ∠ A , b opposite ∠ B , c opposite ∠ C
we require to calculate ∠ C
∠ C = 180° - (64 + 85)° = 180° - 149° = 31°
then to find a , using
\(\frac{a}{sinA}\) = \(\frac{c}{sinC}\)
\(\frac{a}{sin64}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
a × sin31° = 9.3 × sin64° ( divide both sides by sin31° )
a = \(\frac{9.3sin64}{sin31}\) ≈ 16.23 ( to 2 decimal places )
then to find b , using
\(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
\(\frac{b}{sin85}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
b × sin31° = 9.3 × sin85° ( divide both sides by sin31° )
b = \(\frac{9.3sin85}{sin31}\) ≈ 17.99 ( to 2 decimal places )

Penelope is taking a multiple choice test with a total of 40 points available. Each
question is worth exactly 5 points. What would be Penelope's test score (out of 40) if
she got 3 questions wrong? What would be her score if she got x questions wrong?
Answer:
1) 62.5%
2) 8-x/8=y/100 (where y is the percent)
Step-by-step explanation:
1) so there’s 8 questions in total cause each question si 5 points and 40 points is the max so 40/5=8
write a proportion where 8-3/8=y/100 (it’s 8-3 because it’s total question minus the wrong questions and you’ll get the remaining points and put it over a hundred since the max score you can get is a hundred.
so 5/8= y/100
cross multiply
500=8y
Divide 8 on both sides
you’ll get 62.5
2) Jist use the equation 8-x/8=y/100

3 cos x + 2
The function is f(x) = 3 sin x

The equation of the sinusoid function is:
3 Sin πx + 2.
Let's analyze the given options to find the correct equation:
a. 3 Cos πx + 2:
This option is a cosine function with a vertical shift of 2, but it does not have the correct amplitude or period. Therefore, it is not the correct equation.
b. 3 Sin x: This option is a sine function with the correct amplitude, but it does not have the correct vertical shift or period. Therefore, it is not the correct equation.
c. 3 Sin πx + 2: This option is a sine function with the correct amplitude and vertical shift. Let's check if it has the correct period:
To determine if the period is correct, we need to calculate the x-values when the function repeats itself.
In this case, we need to find x-values such that sin(πx) = 0, since the function will reach its maximum and minimum points again at those x-values.
sin(πx) = 0 when πx = 0, π, 2π, 3π, ...
Solving for x, we have:
πx = 0 ⟹ x = 0
πx = π ⟹ x = 1
πx = 2π ⟹ x = 2
πx = 3π ⟹ x = 3
From this, we can see that the function repeats itself every integer value of x, which matches the given information.
Therefore, option (c) is the correct equation: 3 Sin πx + 2.
Option (d) 3 Cos x does not have the correct vertical shift or period, so it is not the correct equation.
Hence, the equation of the sinusoid function is:
3 Sin πx + 2.

An estimator is said to be consistent if: the difference between the estimator and the population parameter grows smaller as the sample size grows larger. it is an unbiased estimator. the variance of the estimator is zero. the difference between the estimator and the population parameter stays the same as the sample size grows larger.
Answer:
the difference between the estimator and the population parameter grows smaller as the sample size grows larger.
Step-by-step explanation:
In Statistics, an estimator is a statistical value or quantity, which is used to estimate a parameter.
Generally, parameters are the determinants of the probability distribution. Thus, to determine a normal distribution we would use the parameters, mean and variance of the population.
An estimator is said to be consistent if the difference between the estimator and the population parameter grows smaller as the sample size grows larger. This simply means that, for an estimator to be consistent it must have both a small bias and small variance.
Also, note that the bias of an estimator (b) that estimates a parameter (p) is given by; \(E(b) - p[\tex]
Hence, an unbiased estimator is an estimator that has an expected value that is equal to the parameter i.e the value of its bias is equal to zero (0).
A sample variance is an unbiased estimator of the population variance while the sample mean is an unbiased estimator of the population mean.
Generally, a consistent estimator in statistics is one which gives values that are close enough to the exact value in a population.
