We'll use the tangent rule since it connects the opposite and adjacent side.
tan(angle) = opposite/adjacent
tan(42) = x/20
20*tan(42) = x
x = 20*tan(42)
x = 18.00808
x = 18
The value is approximate.
Rounding 18.00808 to the nearest tenth leads to 18.0 which is the same as 18

A well-mixed cookie dough will produce cookies with a mean of 8 chocolate chips apiece. What is the probability of getting a cookie with no more than 3 chips
Answers
Answer:
The probability of getting a cookie with no more than 3 chips is 0.0424.
Step-by-step explanation:
Let X number of chocolate chips apiece of cookie.
The mean number of chocolate chips apiece is λ = 8.
The random variable X follows a Poisson distribution with parameter λ = 8.
Compute the probability of getting a cookie with no more than 3 chips as follows:
[tex]P(X\leq 3)=\sum\limits^{3}_{x=0}{\frac{e^{-8}(8)^{x}}{x!}}[/tex]
[tex]=0.00034+0.00268+0.01073+0.02863\\=0.04238\\\approx 0.0424[/tex]
Thus, the probability of getting a cookie with no more than 3 chips is 0.0424.

One evening, a restaurant served a total of 1/2 of a loaf of wheat bread and 7/8 of a loaf of white bread. How many loaves were served in all?
Answers
Answer:
[tex]\dfrac{11}{8}[/tex]
Step-by-step explanation:
A restaurant served a total of 1/2 of a loaf of wheat bread and 7/8 of a loaf of white bread.
We need to find how many loaves were served in all. It is equal to the sum of the fraction of 1/2 and 7/8.
Sum of these two fractions :
[tex]\dfrac{1}{2}+\dfrac{7}{8}\\\\=\dfrac{4+7}{8}\\\\=\dfrac{11}{8}[/tex]
So, a total of 11/8 were served in all.

Solve the equation for the variable y in terms of the variable x. 4x + y = 6
Answers
Answer:
y = -4x + 6
Step-by-step explanation:
To solve for y in terms of x, isolate y.
To get y by itself, subtract 4x from both sides:
4x + y = 6
y = -4x + 6
So, y in terms of x is y = -4x + 6
Answer:
y = − 6 + 4 x

1. Which of these statements describes a key distinction between an observational study and an experimental study?
A: Experimental studies are more representative of the larger population than observational studies.
B: Data is collected in experimental studies, but not in observational studies.
c: Observational studies try to answer a question, but experimental studies do not.
D: Experimental studies directly influence something to see its effect, but observational studies do not directly influence the subjects.
Answers
Answer: Experimental studies directly influence something to see its effect, but observational studies do not directly influence the subjects.
Step-by-step explanation:
The correct option is D.
In an experimental study, you perform an experiment. In an experiment are made with the objective of validating, refute, or support a given hypothesis, where you observe "what happens" when you modify a given set of parameters. Always in an experiment, we can define the independent and dependent variables, where the independent are the ones that we can modify at will, and the dependent ones are the ones that we observe to see how they react to the changes in the independent variables.
In observational studies, the idea is not changing anything in the object of study, so the scientist in this case are only observers or spectators.
x:y=5 :3 and x+y=56 work out x-y
Answers
Answer:
The value of x - y is 14
Step-by-step explanation:
∵ x : y = 5 : 3
→ Write it in the form of the fraction
∴ [tex]\frac{x}{y}=\frac{5}{3}[/tex]
→ Multiply both sides by y
∴ [tex]\frac{x}{y}[/tex] × y = [tex]\frac{5}{3}[/tex] × y
∴ x = [tex]\frac{5}{3}[/tex] y ⇒ (1)
∵ x + y = 56 ⇒ (2)
→ Substitute x in (2) by (1)
∴ [tex]\frac{5}{3}[/tex] y + y = 56
→ Add the like terms
∵ [tex]\frac{8}{3}[/tex] y = 56
→ Divide both sides by [tex]\frac{8}{3}[/tex]
∴ y = 21
→ Substitute the value of y in (1) to find x
∵ x = [tex]\frac{5}{3}[/tex] (21)
∴ x = 35
→ Now find the value of x - y
∵ x - y = 35 - 21
∴ x - y = 14
∴ The value of x - y is 14

which is equivalent to 60minutes which is the sample space
and the sample size which is 10 minutes.
then the probability of a taxi arriving in 10minutes seeing that you have been waiting for over 60minutes is
Pr(taxi arrives in 10 min)= 10/60= 1/6
thus the probability is 1/6

A shipment of 8 parrots from Brazil includes 2 parrots with a potentially fatal disease. As usual, the U. S. Customs Office at the shipment's point of entry randomly samples 4 parrots and tests them for disease. What is the probability that the first three parrots selected are healthy
Answers
Answer:
5 / 14
Step-by-step explanation:
Given that:
Number of parrots shipped = 8
Number of defective parrots = 2
Number of Random samples tested = 4
Number of healthy parrots = 8 - 2 = 6
Probability that first 3 parrots are healthy:
P(1st parrot) * p(2nd parrot) + p(3rd parrot)
P = (number of required outcomes / number of total possible)
USing sampling without replacement :
P(1st parrot healthy ) = 6/ 8 = 3/4
P(2nd parrot healthy) = 5 / 7
P(3rd parrot healthy) = 4 / 6 = 2/3
P(first 3 parrots being healthy) :
(3/4) * (5/7) * (2/3) = 30/84 = 5 / 14
