Answer:
[tex]a = 8.5t[/tex]
[tex]y = 32.55[/tex]
Step-by-step explanation:
Solving (9): The equation of the table
We start by calculating the slope (m)
[tex]m = \frac{a_2 - a_1}{t_2 - t_1}[/tex]
Where:
[tex](t_1,a_1) = (15,127.5)[/tex]
[tex](t_2,a_2) = (16.5,140.25)[/tex]
[tex]m = \frac{140.25 - 127.5}{16.5 - 15}[/tex]
[tex]m = \frac{12.75}{1.5}[/tex]
[tex]m = 8.5[/tex]
The equation is then calculated using:
[tex]a = m(t - t_2) + a_2[/tex]
So, we have:
[tex]a = 8.5(t - 16.5) + 140.25[/tex]
Open bracket
[tex]a = 8.5t - 140.25 + 140.25[/tex]
[tex]a = 8.5t[/tex]
Solving (10):
[tex]4.8y = 156.24[/tex]
Required
Find x
Divide both sides by 4.8
[tex]y = 32.55[/tex]
habitantes de dos pequenas comunidades harán una obra de drenaje que
beneficia a todos. El costo de los materiales necesarios asciende a 360,000.00
Se decidió que las aportaciones sean proporcionales al numero de habitantes de
da comunidad. En la comunidad A hay 120 habitantes; en la comunidad B 240
y en la comunidad C 360
¿Con cuánto debe cooperar cada comunidad?
¿Cuál es la aportación por persona en las tres comunidades?
Answer:
La Comunidad A deberá aportar $60,000, la Comunidad B deberá aportar $120,000 y la Comunidad C deberá aportar $180,000. Cada Comunidad aportará $500 por persona.
Step-by-step explanation:
Dado que la obra de drenaje tiene un costo de materiales de $360,000, y que dicho costo será soportado por cada comunidad en proporción a sus habitantes, sabiendo que en la comunidad A hay 120 habitantes; en la comunidad B 240 y en la comunidad C 360, para determinar con cuánto dinero debe cooperar cada una se debe realizar el siguiente cálculo:
120 + 240 + 360 = 720
C = 1/2 x 360,000 = 180,000
B = 1/3 x 360,000 = 120,000
A = 1/6 x 360,000 = 60,000
Así, la Comunidad A deberá aportar $60,000, la Comunidad B deberá aportar $120,000 y la Comunidad C deberá aportar $180,000.
A su vez, la aportación por persona en las tres comunidades surge del siguiente cálculo:
360,000 / 720 = 500
Así, cada comunidad aportará $500 por persona.

If (X + A) is multiplied times (X + B), the final term of the resulting trinomial will be:
Answer:
AB
Step-by-step explanation:
Using FOIL (first outer inner last) u can determine that the final term will be produced by multiplying the last terms in each bracket. These are A and B, so the final term of the resulting trinomial is AB.
You can check this by fully expanding (x + A)(x + B):
[tex](x + A)(x + B)\\= x^{2} + Bx + Ax + AB[/tex]
the terms B and A are usually numbers, so Bx and Ax tend to get added together to form a middle term. hope this helps!
I WILL MARK BRAINLIEST :) Determine which segment is shortest in the diagram.
Answer:
C.
Step-by-step explanation:
Answer:
C. Segment AC
Step-by-step explanation:
I am going to figure all the angles first. Triangles always add up to 180 degrees so I am going to use that.
50 + 49 = 99
180 - 99 = 81
<C = 81°
99 + 37 = 136
180 - 136 = 44
<A = 44°
The shortest segment is always going to be opposite the smallest angle. The smallest angle is 37°. Therefore, Segment AC is the shortest.

A construction worker dropped a hammer while building the Grand Canyon skywalk, 4000 feet above the Colorado River. Use the formula, t = h 4 , to find how many seconds it took for the hammer to reach the river. Round your answer to the nearest second.
Answer: Hammer reaches river after 15.8 seconds.
Step-by-step explanation:
Use formula: t = square root of h divided by 4. In this problem h = 4,000.
Therefore,
T = square root of 4,000 divided by 4.
T = 15.8 seconds

A study shows that unemployment has not impacted white-collar and blue-collar workers equally (Newsweek, April 20, 2009). According to the Bureau of Labor Statistics report, while the national unemployment rate is 8.5%, it is only 4.3% for those with a college degree. It is fair to assume that 27% of people in the labor force are college educated. You have just heard that another worker in a large firm has been laid off. What is the probability that the worker is college educated
Answer:
0.137
Step-by-step explanation:
The computation is shown below:
Educated = 0.27
And, unemployed to educated is 0.043
Now probability of educated and unemployed is
= 0.043 × 0.27
= 0.1161
So, the educated would be
= 0.01161 ÷ 0.085
= 0.137
is 1.75 greater than 1.5
Yes, the fraction 1.75 is greater than the 1.5.
What are fraction numbers?In mathematics, a fraction is a numerical value that expresses a portion of a total. The term "whole" can refer to any number, a certain value, or an object. The fraction symbol is written as p/q. For instance, 1/4, 1/2, 3/4, and so forth.
Two whole numbers (the fraction terms) separated by a horizontal line are used to calculate the fractional numbers (the fraction line).
In this Question, the fraction is represented as a decimal number. Since
the number before the decimal is the same. Thus we will compare the value of the number that is after the decimal. here we can see 75 is greater than 50.
Therefore, It is true that the fraction 1.75 is larger than 1.5.

What is the distance between the points (-2, 1) and(1,3) ?Round your answer to the nearest tenth
To answer this question we're going to need to use the distance formula, which is
d = √((x2 - x1)2 + (y2 - y1)2)
We are given two points:
(x1, y1) = (-2, 1)
(x2, y2) = (-5, 3)
d = √((-5 - (-2))2 + (3 - 1)2)
= √((-3)2 + (2)2)
= √(9 + 4)
= √(13)
≈ 3.6056
Since it says to round to the nearest tenth, the distance between the 2 points is
3.6 units

Assume you are planning a picnic for lunch, but when you woke up there were rain clouds in the sky. If 50% of rainy days start with rain clouds in the air, 20% of all days start with clouds in the air, and rain only typically occurs on 1 out of every 10 days, what is the probability that it will rain today and ruin your picnic
Answer:
0.25 = 25% probability that it will rain today and ruin your picnic
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Cloudy skies
Event B: Rain
20% of all days start with clouds in the air
This means that [tex]P(A) = 0.2[/tex]
50% of rainy days start with rain clouds in the air
50% of 10%. So
[tex]P(A \cap B) = 0.5*0.1 = 0.05[/tex]
What is the probability that it will rain today and ruin your picnic
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.2} = 0.25[/tex]
0.25 = 25% probability that it will rain today and ruin your picnic

Dennis is getting balloons for his grandmother's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Dennis wants to get 56 balloons, how many yards of string will he need?
1 foot = 1/3 yard
Answer:
168 yards
Step-by-step explanation:
3 feet = 1 yard
9 (ft for each balloon) x 56 (# of balloons.) = 504 (ft of string needed in total)
504 (ft in total) divided by 3 (three feet = 1 yard) = 168 (yards of string needed)

14 16 12 12 11 5 11 4
Answer:
See explanation and attached file
Step-by-step explanation:
A dot plot is a chart that is created using data points. It is one of the easiest ways of plotting the distribution of data and they make it a lot easier to see data. It is like a bar chart but instead of bars, you have dots.
It is created by counting the number of data that a particular variable has and drawing the corresponding number of dots above it.

The population of a community is known to increase at a rate proportional to the number of people present at time t. If an initial population P0 has doubled in 3 years, how long will it take to triple? (Round your answer to one decimal place.)
Answer:
4.75 years are required to triple the population
Step-by-step explanation:
As we know
[tex]\frac{dP}{dt} = P\\[/tex]
Integrating both the side with respect to t we get
[tex]ln P = kt + c_1\\P = e^{kt + c_1}\\P = Ce^{kt}[/tex]
At t = 0, P = P0
[tex]2 P_0 = P_0 * e ^{3k}\\2 = e ^{3k}\\ln 2 = 3k\\k = 0.231\\[/tex]
substituting K value in main equation, we get -
[tex]P = P_0 * e^{0.231 * t}\\3P_0 = P_0 * e^{0.231 * t}\\3 = e^{0.231 * t}\\ln 3 = 0.231 * t\\t = 4.75[/tex]
4.75 years are required to triple the population
