Gabriel earns $146.25 for working 15 hours. Maria earns $205.00 for working 20 hours. Who earns the most money per hour and how much more?
Please help have to turn in tomorrow
you get 15 points!!!!
Answers
Answer: Maria makes $0.50 more per hour
Step-by-step explanation: Doing $146.25/15 and $205/20 you can find that Gabriel makes $9.75/hr and Maria makes $10.25/hr
Answer: Maria makes more, 50 cents more per hour.
Step-by-step explanation:
To solve divide the number of money they made by the amount of hours they worked. 146.25/15=9.75. Gabriel made 9.75 an hour,
205/20=10.25 Maria made 10.25 an hour.
Maria earned the most money per hour.
To find how much more she made subtract the person who made more money by the person who made less money per hour. 10.25-9.75=0.5 Maria earned an extra 50 cents per hour compared to Gabriel.

Step-by-step explanation:
Given :
1 answer from 4 options
p = 1/4 = 0.25 ; q = 1 - 0.25 = 0.75
n = 20
P(x ≤ 3) = p(x =0) +p(x=1) + p(x=2) +p(x=3)
P(x = x) = nCr * p^x * q^(n-r)
p(x =0) = 20C0 * 0.25^0 * 0.75^20 = 0.00317
p(x =1) = 20C1 * 0.25^1 * 0.75^19 = 0.02114
p(x =2) = 20C2 * 0.25^2 * 0.75^18 = 0.06694
p(x =3) = 20C3 * 0.25^3 * 0.75^17 = 0.13389
P(x ≤ 3) = 0.00317+0.02114+0.06694+0.13389 = 0.22514

Michelle throws a ball vertically upward from the top of a cliff. The height of the ball above the base of
the cliff is approximated by the model H=65+10t – 5t, where H is the height in metres and t is the
time in seconds. How long does it take the ball to reach a height of 50 m above the base of the cliff?
Answers
Answer:
1/2 seconds
Step-by-step explanation:
h(t) = 65 + 10t - 5t^2
h(t) = -5t^2 + 10t + 65
the max height is reached at the vertex.
the value of t at the vertex is:
t = -b/(2a)
t = -10/(2(-10))
t = -10/(-20)
t = 10/(20)
t = 1/2 seconds

X does not repeat if it is a function.
So, if you are finding the function it is one where x is different every time
Step-by-step explanation:
Based on the given graph, we can infer and logically conclude that the values of x for which this function is continuous is equal to zero (0).
What is a continuous function?A continuous function can be defined as a type of function in which there is no discontinuities or breaks between the intervals for the points plotted on a graph.
By critically observing the graph, we can infer and logically conclude that the values of x for which the function is continuous is zero (0) because it marks the point of continuity.

2. True or false:
The ordered pair (0, 4) is a solution for the equation:

Answers
1) true
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23

23=23
thus, (3,4) is solution for 5x + 2y = 23

thus, (0,4) is not solution for 5x + 2y = 23

A reproductive clinic had a success rate of 25% of patients with live births in 2008. They want to update their success rate (the proportion of live births) for 2020. If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval? Round your answer up to the nearest integer.
Answers
Answer:
They should sample the results of 1990 patient results.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
A reproductive clinic had a success rate of 25% of patients with live births in 2008.
This means that [tex]\pi = 0.25[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval?
They should sample n patients.
n is found for [tex]M = 0.025[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.025 = 2.575\sqrt{\frac{0.25*0.75}{n}}[/tex]
[tex]0.025\sqrt{n} = 2.575\sqrt{0.25*0.75}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.25*0.75}}{0.025}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575\sqrt{0.25*0.75}}{0.025})^2[/tex]
[tex]n = 1989.2[/tex]
Rounding up:
They should sample the results of 1990 patient results.
