There is a traffic light at the intersection of walnut street and Lawrence avenue. The traffic light in walnut street follows a cycle. It is green for 50 seconds, yellow for 10 seconds, and red for 30 seconds, as you travel along walnut and approach the intersection, what is the probability that the first color you see is red?
Answer: The probability that the first color we see is red is 0.34.
Step-by-step explanation:
Since we have given that
Time taken by green color on the traffic light = 50 seconds
Time taken by yellow color on the traffic light = 10 seconds
Time taken by red color on the traffic light = 30 seconds
Total number of seconds = 50+10+30=90
So, Probability that the first color we see is red is given by
[tex]\dfrac{\text{Time alloted for red color}}{\text{Total number of seconds}}\\\\=\dfrac{30}{90}\\\\=\dfrac{1}{3}\\\\=0.3333...\\\\\approx 0.34[/tex]
Hence, the probability that the first color we see is red is 0.34.

If a seed is planted, it has a 90% chance of growing into a healthy plant. if 7 seeds are planted, what is the probability that exactly 4 don't grow?
Answer:
0.098415
Step-by-step explanation:
The way the question is worded is odd and you should probably actually include “don’t grow into a healthy plant” or something. You can use the binomial distribution. Suppose ∼Bin(6,0.1) so the probability that k trees don’t grow into a healthy plant is
Pr( = ) = (6 / ) 0.16^ 0.9^6−
Then the probability that two don’t grow into healthy plants is
Pr( = 2) = (6/2) 0.1^2 0.9^4
this is equal to 0.098415
To calculate the probability of exactly 4 out of 7 seeds failing to grow, use the binomial probability formula with n = 7, p = 0.10, and k = 4. The calculation involves combinations and exponentiation.
Explanation:The question is asking for the probability of exactly 4 seeds out of 7 failing to grow. Given that each seed has a 90% chance of growing into a healthy plant, which means each seed has a 10% (1 - 0.90) chance of not growing. To solve this, we can use the binomial probability formula: P(X = k) = C(n, k) * (pk) * ((1 - p)n - k), where n is the number of trials, p is the probability of success, and k is the exact number of successes. In this case, n = 7, p = 0.10 and k = 4. So, we get:
P(X = 4) = C(7, 4) * (0.104) * (0.907 - 4)
The calculation of this probability requires the use of combinations and exponentiation, providing the specific likelihood of having exactly 4 seeds out of 7 not growing into a healthy plant.

What can you say about the nature of any other zeros of the quadratic equation which has one complex zero? Explain your answer.
If EF = HG and HG = 16, find the diameter of K
Answer:
Diameter of the circle K = 20 units
Step-by-step explanation:
Given that : EF = HG
Also, HG = 16 units
⇒ EF = 16 units
Now, any line drawn perpendicular to the chord always bisects the chord
⇒ KI will bisect the chord EF
⇒ EI = 8 units
Now, in ΔEIK using Pythagoras theorem we have :
⇒ EK² = 8² + 6²
⇒ EK² = 100
⇒ EK = 10 units
So, Radius of the circle K = 10 units
Now, Diameter of the circle K = 2 × 10
= 20 units
True or false the rules of two dimensional geometry can be applied to three dimensional solids
Answer:
the answer is TRUE.
Step-by-step explanation:
we can coclude that the three-dimensional geometry is more or less the extension of a two-dimensional geometry as many of the same principles imply.
two points determine a straight line no matter whether the points are two-dimensional or three-dimensional.
hence the following statements holds true that the rules of two dimensional geometry can be applied to three dimensional solids.

Hosting a breakfast for 25 people you plan to serve scrambled eggs the grocery store sells eggs in cartons and each carton can feed people. how many cartoons of eggs must you buy to ensure each guest a serving
The number of egg cartons required to serve 25 people with scrambled eggs is 3 cartons, assuming each carton serves 12 people and we cannot purchase partial cartons.
To calculate the number of egg cartons needed to serve scrambled eggs to 25 people, we first need to know how many people each carton can serve. However, it appears there's a typo or missing information in the question regarding the number of people an egg carton can serve. Assuming that one egg carton can serve a certain number of people, we'd use that information to determine the total number of cartons required.
If we refer to the related information provided about pancakes - where one egg is needed for 8 pancakes - we can draw a parallel for eggs for scrambled eggs. If one egg serves one person in the case of scrambled eggs, and typically there are 12 eggs in a carton, then one carton would serve 12 people.
Using this assumption, since we have 25 people to serve, we can calculate the number of cartons needed as follows:
25 people
Since we cannot purchase a partial carton, we would need to round up to the nearest whole number. Therefore, we would need to purchase 3 cartons of eggs to ensure each guest has a serving.

The following table shows the expressions that represent the sales of 4 companies: Company A B C D Sales 170(1.04)x 330(1.80)x 250(0.06)x 120(1.09)x Rank the company sales by smallest to largest percent of increase and select the correct answer below.
To rank the company sales by smallest to largest percent of increase, calculate the percent of increase for each company, which in this case is 0% for all companies.
Explanation:To rank the company sales by smallest to largest percent of increase, we need to calculate the percent of increase for each company. The percent of increase can be found by subtracting the initial value from the final value, dividing that number by the initial value, and then multiplying by 100.
For company A: Percent of increase = ((170(1.04)x - 170(1.04)x) / (170(1.04)x)) * 100 = 0%For company B: Percent of increase = ((330(1.80)x - 330(1.80)x) / (330(1.80)x)) * 100 = 0%For company C: Percent of increase = ((250(0.06)x - 250(0.06)x) / (250(0.06)x)) * 100 = 0%For company D: Percent of increase = ((120(1.09)x - 120(1.09)x) / (120(1.09)x)) * 100 = 0%Since all the percent of increase values are 0%, the company sales can be ranked in any order, as there is no change in sales for any of the companies.

Robinson's home run hitting distance is normally distributed with a mean of 394 feet and a standard deviation of 35 feet. He wanted to find the probability that his home runs traveled at least 380 feet. He calculated the z-score to be −0.40 and looked up the probability on the Standard Normal Probabilities table. He found that the table stated his probability as 0.3446. Determine whether Robinson made an error in his calculation and explain.
I need step by step instructions
Answer:
he made an error, the probability that his homeruns traveled at least 380 feet is 65.54%
Step-by-step explanation:
let´s see the Robinson's calculation:
using the formula for normal distribution:
Z = (x-μ)(σ/[tex]\sqrt{n}[/tex]) [1]
where:
x is raw measurement
μ is the mean
σ is the standar deviation
n is the size of sample
in this case x = 380, μ = 394, σ = 35, n = 1.
then using the equation [1] he calculated the Z score:
[tex]Z = \frac{380-394}{\frac{35}{\sqrt{1}}}\\\\Z = -\frac{14}{35}\\\\Z = -0.4\\\\[/tex]
and it's correct but his answer is wrong because he confuse the term at least.
at least means that the probability be greater than 380 feet, not less than 380 feet.
so he looked the Z score in a table of normal distribution (this table has been attached) and effectively this value is 0.3446. but as I told you this probability is for x < 380.
therefore, the probability that his homeruns traveled at least 380 feet is:
[tex]P(x > 380) = 1 - P(x < 380)\\\\P(x > 380) = 1 - 0.3446\\\\P(x > 380) = 0.6554 \ or \ 65.54 \%[/tex]

A bridge in the shape of an arch connects two cities separated by a river. The two ends of the bridge are located at (–7, –13) and (7, –13), and the center of the arch on the bridge is located at (0, 0). Find the equation of the arch of the bridge.
The equation of the arch is y = (-13/49)x².
The equation of an arch can be described by a parabola when one side of the arch mirrors the other side. This is the case for the bridge problem given.
The center of the bridge is at the origin (0, 0), and it is the vertex of the parabola. Since the arch is symmetrical and the x-coordinate of the vertex is 0, the parabola is a vertical one. Thus, the equation will be in the form y = ax². To find the value of a, we will use the fact that one end of the bridge is at (7, -13).
Since (7, -13) is a point on the parabola, by plugging these values into the equation y = ax², we get:
-13 = a(7²)
-13 = 49a
a = -13/49
Thus, the equation is y = (-13/49)x².
The measure of an angle is 60° less than nineteen times the measure of its supplement. what is the measure of the angle?

Given that;
The statement is,
''The measure of an angle is 60° less than nineteen times the measure of its supplement.''
Let measure of an angle = x
So, The measure of its supplement = 180° - x
Hence, We can formulate;
⇒ x = (180 - x) - 60°
Solve for x as;
⇒ x = 180 - x - 60
⇒ x + x = 120
⇒ 2x = 120
⇒ x = 120/2
⇒ x = 60°

At the frozen yogurt shop, a machine fills cups with 4 ounces of frozen yogurt before adding the toppings. After the cups are filled, customers add as many toppings as they want without exceeding a total weight of 6 ounces. Which of the following represent the acceptable weights for the frozen yogurt options? Select all that apply:
A.) 0 < x ≤ 6
B.) 0 < x ≤ 3
C.) 4 ≤ x ≤ 6
D.) x ≤ 6
E.) |x - 5| ≤ 1
F.) |x - 2| ≤ 6
By writing an inequality and then converting it to an absolute value equation, we will see that the correct options are C and E.
How to find an inequality?
To find the inequality, we need to find the lower and upper bounds.
First, we know that the machine fills the cups with 4 oz of yogurt, so this is the minimum value allowed, we will have:
4 ≤ x
Then we can add toppings to a maximum value of 6 ounces, this will be the maximum, then we have:
4 ≤ x ≤ 6
We can also write this an absolute value equation, we define:
m = half of the difference of the bounds.M = lower bound + mThen the absolute value equation is:
|x - M| ≤ m
By replacing what we found before, we have:
m = (6 - 4)/2 = 1M = 4 + 1 = 5So the absolute value equation is:
|x - 5| ≤ 1
Finally, we can conclude that the correct options are C and E.
