it D that the fertilizer with the urea supplement is more effective than the fertilizer without it.
A histogram is the way of representation of data that is utilized to appear the frequency distribution utilizing the rectangle comparable to a bar graph. in order to decide which fertilizer is superior for plant development Farmers conducted a survey consisting of one fertilizer containing an urea supplement, whereas the other does not contain a urea supplement. in which they haphazardly chose 20 plants of the same species developing in their region. ten out of 20 on which the urea-enhanced fertilizer was applied and the rest with the non-urea fertilizer on the other 10 plants. So After three months At just the beginning of the month, 4 plants showed normal development with the urea supplement, whereas as it were 2 plants appeared to this development when urea isn't supplied. for the second month, 7 plants showed normal development with urea supplement, whereas 4 plants appeared this growth when urea isn't supplied and in the last month of the experiment, 5 plants showed over normal development.

Step-by-step explanation:
a biased coin lands heads with probability 2/3. the coin is tossed three times. a) given that there was at least one head in the three tosses, what is the probability that there were at least two heads? b) use your answer in a) to find the probability that there was exactly one head, given that there was at least one head in the three tosses.
The probability that one head in the three tosses, at least two heads is 0.7692, and the probability that exactly one head, at least one head in the three tosses is 0.2308.
What is a toss?
Probability indicates the likelihood of an event.That whenever a coin is tossed, there are only two possible outcomes. Head and Tail are those. In light of the probability formula above, the coin toss probability calculation is as follows:Formula for Probability of a Coin Toss: (Number of Successful Outcomes) (Total occurances of possible outcomes)
It's a binomial distribution with n=3, P=2/3
(a) P(one head in the three tosses, at least two heads)
P(x≥2 | x≥1)=[P(x≥2)∩P(x≥1)]/P(x≥1)
=0.7407/0.9630
=0.7692
(b) P(exactly one head, at least one head in the three tosses)
P(x=1 | x≥1)=[P(x=1∩ (x≥1)]/P(x≥1)
=0.222/0/9630
=0.2308
The probability that one head in the three tosses, at least two heads is 0.7692, and the probability that exactly one head, at least one head in the three tosses is 0.2308.

1. (02.06 mc) a car travels 25.0 miles due east for one hour. then it travels another 60.0 miles east for an additional hour. what is the average velocity of the entire trip? (2 points) 17.5 mph east 35.0 mph east 42.5 mph east 85.0 mph east
The average velocity of the entire trip is 42.5 mph east
An object's average velocity is calculated by dividing its total displacement by its total travel time.
It measures how quickly an object shifts from one location to another.
It is a Vector magnitude
For one hour, an automobile travels 25.0 miles due east.
Then it continues for an extra hour and travels another 60.0 miles east.
We must determine his overall journey average speed.
He does the entire journey going straight east.
He travels a total distance of 25 + 60 = 85 miles east.
He takes an hour to get there from here and another hour to get there from there.
The total travel time is 1 + 1 = 2 hours.
Total displacement times total time equals the average velocity.
His average speed = 85 ÷ 2 = 42.5 miles/hour east
The average velocity of the entire trip is 42.5 mph east

what will increase the width of a confidence interval? a) increase number in sample b) decrease confidence level. c) decrease variance d) increase variance.
The width of a confidence interval decreases as the sample size increases and increases as the confidence level increases.
What is a confidence interval?A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. A confidence interval is calculated at a certain confidence level; the 95% confidence level is the most commonly used, although other levels, such as 90% or 99%, are also employed.So, we know that smaller samples result in narrower intervals.
With a higher sample size, we can more precisely estimate a population proportion.Therefore, a confidence interval narrows as the sample size grows and widens as the level of confidence rises.

7. Here is an inequality: -7- (3x+2) <-8(x + 1)
Select all the values of x that are solutions to the inequality.
A. x = -0.2
B. x = -0.1
C.x=0
D. x = 0.1
E. x = 0.2
F. x = 0.3
(From Unit 2, Lesson 19.)
Answer:
A,B,C,D
Step-by-step explanation:
-7-(3x+2) <=8(x+1)
-7-3x-2<-8x-8
5x<1
x<1/5
x= -0.2, X=-0.1, X=0, X=0.1
The values of x that are solutions to the inequality are C (x = 0) and D (x = 0.1).
Given inequality: -7 - (3x + 2) < -8(x + 1)
Let's solve the inequality step by step:
Distribute the -8 on the right side:
-7 - 3x - 2 < -8x - 8
Combine like terms on both sides:
-9 - 3x < -8x - 8
Add 8x to both sides to isolate the variable terms on one side:
8x - 3x - 9 < -8
Simplify the left side:
5x - 9 < -8
Add 9 to both sides:
5x < 1
Divide both sides by 5 (since 5 is positive, the direction of the inequality does not change):
x < 0.2
Now, let's compare the solutions to the given options:
A. x = -0.2: Not a solution (not less than 0.2)B. x = -0.1: Not a solution (not less than 0.2)C. x = 0: Solution (0 is less than 0.2)D. x = 0.1: Solution (0.1 is less than 0.2)E. x = 0.2: Not a solution (not less than 0.2)F. x = 0.3: Not a solution (not less than 0.2)So, the values of x that are solutions to the inequality are C (x = 0) and D (x = 0.1).

B. Vx= 8.66 m/s Vy=5 m/s
C. Vx= 5 m/s Vy=8.66 m/s
D. Vx= 6 m/s Vy=8 m/s
If I throw a ball with an Initial velocity Vi=10 m/s with an angle Theta of 60 degrees above the Horizontal axis x, then the velocity Vx and Vy are; C. Vx= 5 m/s Vy=8.66 m/s
What are the vertical and horizontal components of the velocity?
The formula to find the velocity of an object thrown at an angle is;
Horizontal velocity component; Vx = v_i*cosθ
Vertical velocity component; Vy = v_i*sinθ
where;
v_i is initial velocity
θ is angle at which object is thrown.
Now, we are given that;
Initial velocity; v_i = 10 m/s
Angle of throw; θ = 60°
Thus;
V_x = 10 * cos 60
V_x = 10 * 0.5
V_x = 5 m/s
V_y = 10 * sin 60
V_y = 10 * 0.8660

5) How can we guarantee that a polynomial is not a perfect square, considering just the constant term? For instance, in 4, the constant term is -121, in 2, the constant term is 36. Which of them cannot be a perfect square and why, based only on the constant term?
Polynomials with a negative constant term are not perfect squares, hence polynomial 4, with constant term of -121, is not a perfect square.
What are perfect square expressions?Perfect square expressions are formed in two ways, either with the square of the sum or the square of the subtraction, as follows:
Square of the sum: (a + b)² = a² + 2ab + b².Square of the subtraction: (a - b)² = a² - 2ab + b².The constant term is the final term. Since this term is squared, it will always be positive for perfect squares, hence if the constant term is negative, it will guarantee that the polynomial is not a perfect square.
For the expressions in this problem, we have that:
The expression with a constant term of 36 can be a perfect square, as 36 is a positive number.The expression with a constant term of -121 cannot be a perfect square, as -121 is a negative number.More can be learned about perfect squares at https://brainly.com/question/14584348
