Last month Maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. Let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. If she hiked a total of 90 miles, which equation can be used to find the number of times Maria hiked each trail?A. x + y = 90 B. 5x – 10y = 90 C. 90 – 10y = 5x D. 90 + 10y = 5x

If cos Θ = negative 4 over 7, what are the values of sin Θ and tan Θ?

Answers

given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.

The values of sin theta and tan theta are √45/7 and √45/4 respectively

Trigonometry identity

Given the following trigonometry identity

cos Θ = -4/7

This shows that

Adjacent = 4

Hypotenuse = 7

Determine the opposite

x^2 = 7^2 - 4^2
x^2 = 49 - 4
x^2 = 45
x = √45

Determine the value of sin Θ

sin Θ = opp/hyp

sin Θ = √45/7

Determine the value of tanΘ
tanΘ = opp/adj

tanΘ = √45/4

Hene the values of sin theta and tan theta are √45/7 and √45/4 respectively

The cost to rent a construction crane is $750 per day plus $250 per hour of use. What is the maximum number of hours the crane can be used each day if the rental cost is not exceed $2500 per day ? Write amd solve the inequality

Answers

Let's use x to represent the number of hours since we don't know that.

750+250x<2500
Subtract 750 from both sides.
250x<1750
Divide both sides by 250.
x<7
The most hours that they can do is 7, or it can be less.

Answer:

x = 7

Step-by-step explanation:

x= number of hours

"cost is not exceed $2500 per day"

not exceed = less than

750+250x < 2500

250x< 2500-750

250x < 1750

x < 1750/250

x<7

7 hours

In general, the probability that it rains on Saturday is 25%. If it rains on Saturday, the probability that it rains on Sunday is 50%. If it does not rain on Saturday, the probability that it rains on Sunday is 25%. Given that it rained on Sunday, what is the probability that it rained on Saturday?

Answers

Answer:

40%

Step-by-step explanation:

From the given statements:

The probability that it rains on Saturday is 25%.

P(Sunday)=25%=0.25

Given that it rains on Saturday, the probability that it rains on Sunday is 50%.

P(Sunday|Saturday)=50%=0.5

Given that it does not rain on Saturday, the probability that it rains on Sunday is 25%.

P(Sunday|No Rain on Saturday)=25%=0.25

We are to determine the probability that it rained on Saturday given that it rained on Sunday, P(Saturday|Sunday).

P(No rain on Saturday)=1-P(Saturday)=1-0.25=0.75

Using Bayes Theorem for conditional probability:

P(Saturday|Sunday)=[TeX]\frac{P(Sunday|Saturday)P(Saturday)}{P(Sunday|Saturday)P(Saturday)+P(Sunday|No Rain on Saturday)P(No Rain on Saturday)}[/TeX]

=[TeX]\frac{0.5*0.25}{0.5*0.25+0.25*0.75}[/TeX]

=0.4

There is a 40% probability that it rained on Saturday given that it rains on Sunday.

Final answer:

To find the probability that it rained on Saturday given that it rained on Sunday, we can use Bayes' theorem. We are given the probabilities of rain on Saturday and Sunday, and we can use the law of total probability to calculate the probability of rain on Sunday. Then, using Bayes' theorem, we can determine the probability of rain on Saturday given that it rained on Sunday.

Explanation:

We need to use Bayes' theorem to find the probability that it rained on Saturday given that it rained on Sunday. Let's denote R1 as the event that it rains on Saturday and R2 as the event that it rains on Sunday. We are given P(R1) = 0.25, P(R2|R1) = 0.50, and P(R2|~R1) = 0.25, where ~R1 represents the event that it does not rain on Saturday. We want to find P(R1|R2), which is the probability that it rained on Saturday given that it rained on Sunday.

First, let's find P(R2).
Using the law of total probability, we can express P(R2) as P(R2|R1)P(R1) + P(R2|~R1)P(~R1).
Since P(R2|R1) = 0.50, P(R1) = 0.25, P(R2|~R1) = 0.25, and P(~R1) = 1 - P(R1) = 0.75, we can substitute these values into the equation and calculate P(R2).
Next, we can use Bayes' theorem to find P(R1|R2).
Bayes' theorem states that P(R1|R2) = (P(R2|R1)P(R1))/P(R2).
Substituting the values we know, we get P(R1|R2) = (0.50*0.25)/P(R2).
We can use the value we calculated for P(R2) in the previous step to find P(R1|R2).

Calculating these values will give us the probability that it rained on Saturday given that it rained on Sunday.
