Answer:
A) A two-sample z -test for a difference in population proportions
Step-by-step explanation:
To determine whether a difference in proportions is significant, the two-sample z-test for a difference in population proportions is the most appropriate method for the analysis.
The most appropriate method for analyzing the results is A. A two-sample z-test for a difference in population proportions.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter.
In this scenario, we have two different treatments (medication R and S) applied to two separate samples (150 cat owners each) and we want to determine if there is a significant difference in the proportion of cats with no fleas between the two groups.
This is a classic scenario for a two-sample z-test for a difference in population proportions, which tests the hypothesis that the difference in proportions between two independent populations is equal to zero.
Thus, a two-sample z-test for a difference in population proportions.
Hence, the correct answer would be option (A)

Talia has a daily budget of $94 for a car rental. Write and solve an inequality to find the greatest distance Talia can drive each day while staying in her budget
Answer:
Step-by-step explanation:
Distance traveled by Talia = x
Cost for travelling 'x' miles = x * 0.20 = 0.2x
Daily budget = $94
Inequality,
30 + 0.2x ≤ 94
Solution:
0.2x ≤ 94 - 30
0.2x ≤ 64 {Divide both sides by 0.2
x ≤ 64/0.2
x ≤ 320
Answer:
x ≤ 320

The height, h, in feet of a golf ball above the ground after being hit into the air is given by the equation, h = -16t 2 + 64t, where t is the number of seconds elapsed since the ball was hit. How many seconds does it take for the golf ball to hit the ground?
It will take ---------
seconds for the ball to hit the ground??
Answer:
Step-by-step explanation:
It will hit the ground when height is equal to zero.
-16t^2+64t=0
-16t(t-4)=0
t=4 seconds
The other persons right,
it will take 4 seconds for the ball to hit the ground.

x=10 y=15
x= 30 y=25
x=16 y=21
x= 32 y= 26
Answer:
the last one
Step-by-step explanation:
32+26=58
32-26=6
Answer:
The first number is 32 and the second is 26
Step-by-step explanation:
Let the two numbers be represented by x and y
1) x + y = 58
2) x - y = 6
x = 6 + y, we'll use put this in the first equation.
x + y = 58
6 + y + y = 58
6 + 2y = 58
2y = 58 - 6
2y = 52
2. 2
y=26, now let's find x, again use the first equation
x + y = 58
x + 26 = 58
x = 58 - 26
x = 32

Answer:
3
Step-by-step explanation:
150-94=56
this means we have 56 dollars remaining
each game is 15 dollars and if you bought 3 games that would add up to 45
56-45=11 which isn't enough for another game but will cover tax

If a ball has a rebound ratio of 0, what does that mean?
Answer: The test is conducted with an electromagnetic or vacuum release mechanism which releases a soccer ball from a height of 2 meters. From that the height of the rebound is measured by recording the sound of the first and second bounce. The time between the first and second bounce is measured. Also During a collision, some of the ball's energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height. ... It reaches way higher than from the height it was released.

the sum of a number n and 3 is 9
Answer:
n is 6
Step-by-step explanation:
because sum means addition and if you subtract 9 by 3, you get 6, so we now know that the missing number is 6 because when you add 6 and 3, you get 9. :)
The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.
The sum of a number n and 3 is 9. Then the equation is given below.
n + 3 = 9
Simplify the equation, then we have
n + 3 = 9
n = 9 - 3
n = 6
The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.

Calculate the side lengths a and b to two decimal places.
Answer:
Below in bold.
Step-by-step explanation:
m < C = 180 - 43 - 115 = 22 degrees.
Using the Sine Rule:
6 / sin 22 = a / sin 43
a sin 22 = 6 sin 43
a = 6 sin 43 / sin 22
a = 10.92 to 2 DP's.
Applying the same rule to calculate b:
6 / sin 22 = b / sin 115
b = 6 sin 115 / sin 22
b = 14.52 to 2 DP's.
