The options to the questions are:
A. Taking on a job can cut into study time
B. Paying with credit cards can end up conting more money
C. Paying with additional loans can lead to connections and opportunities
D. Taking on a job can make connections that lead to opportunities
Answer:
C. Paying with additional loans can lead to connections and opportunities
Step-by-step explanation:
When faced with needing additional money during college, an individual may chose to take on job so to get extra money to finance his or her needs. However, such venture often leads to redcution in study time, as working on jobs will also needs it own time of execution.
Also, paying for financial needs during college days with credit card can lead to counting more money on the card. This implies that one can accumulate credit card rewards which can be in form of cashback, or points from certain purchases when using credit card.
More so, taking a job during college days, will definitely brings connections with different people, and thereby leads to opportunities.
However, paying with additional loans will never lead to connections and opportunities, but rather more debt, that the debtor will have to pay, which may take months or years. And it can only be a burden on the debtor.
Hence, when faced with needing additional money during college the option that is NOT true is Paying with additional loans can lead to connections and opportunities
Tom plants 3 seeds.
The probability that a seed will germinate is 4/5.
A) Calculate the probability that all 3 seeds will germinate.
B) Calculate the probability that at least one of the seeds will germinate.
Answer:
A. 64/125
B. 124/125.
Step-by-step explanation:
A). As the events ( germinate or not germinate) are independent we multiply the probabilities.
Prob(All seeds germinate) = 4/5*4/5*4/5 = 64/125.
B). Probability of at least one germinating = 1 - probability that none germinate
Probability of 1 seed not germinating = 1 -45 = 1/5.
So Prob(at least one germinating)
= 1 - (1/5 * 1/5 * 1/5)
= 1 - 1/125
= 124/125.
The probability that all 3 seeds will germinate is 64/125 and the probability that at least one of the seeds will germinate is 124/125.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
(A)
The probability of all seeds will germinate will be the product of individual probability since all events are independent.
4/5 × 4/5 × 4/5 = 64/125.
B)
Probability of at least one germinating = 1 - the probability that none germinate
The probability of 1 seed not germinating will be given as,
1 -4/5 = 1/5
Thus, the probability of all three seeds not germinating = 1/5 × 1/5 × 1/5
Thus, the probability that at least 1 of the seeds will germinate.
⇒ 1 - (1/5 × 1/5 × 1/5)
⇒ 1 - 1/125
⇒ 124/125
Hence "The probability that all 3 seeds will germinate is 64/125 and the probability that at least one of the seeds will germinate is 124/125".

Super Dave Osborne stands at the bottom of a canyon elevation 256 feet below sea level, he throws a piano up at a velocity of 320 feet per second the piano lands on the edge of the cliff at zero elevation . The flight of the piano is modeled by the equation f( x ) = −16t2 2 + 320t − 256. The piano was in the air for exactly how many seconds
Answer:
The piano was in the air for 18.34 seconds.
Step-by-step explanation:
The height of the piano after t seconds is given by the following equation:
[tex]f(t) = -16t^{2} + 320t - 256[/tex]
Initially, the piano is below the ground level. At the first root of the equation, it will go into the air, and then some time after that it will fall down again, which is at the second root of the equation.
Roots of a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:
[tex]f(t) = -16t^{2} + 320t - 256[/tex]
So
[tex]a = -16, b = 320, c = -256[/tex]
[tex]\bigtriangleup = (320)^{2} - 4*(-16)*(-256) = 86016[/tex]
[tex]t_{1} = \frac{-320 + \sqrt{86016}}{2*(-16)} = 0.8348[/tex]
[tex]t_{2} = \frac{-320 - \sqrt{86016}}{2*(-16)} = 19.17[/tex]
Subtracting:
19.17 - 0.8348 = 18.34
The piano was in the air for 18.34 seconds.

h(t)=-5t^2+10t+3 is the height of a diver above the water, t seconds after the diver leaves the springboard. How high above the water is the springboard?
Answer:
3 units
Step-by-step explanation:
So if we want to know how high the spring board is, this will need to be the time at which the diver is still at the top of the board, in this case t = 0 seconds.
So we will need to find h(0)
h(0) = 5(0)² + 10(0) + 3 = 0 + 0 + 3 = 3April’s garden has 42 plants in each row. She has 2 rows of yellow corn and 20 rows of white corn.
SHOW how much yellow corn and white corn has been planted in the garden.
Please answer using complete sentences. Use of diagrams, tables, or charts will increase grade. Be sure to show your expressions and or equations in your explanation.
Answer:
There are a total of 84 yellow corns and
840 white corns planted in the garden.
Step-by-step explanation:
Number of plants in each row = 42
Number of rows of yellow corn = 2
Number of rows of white corn = 20
To find the total number of yellow corns planted in the garden, we need to add the number of plants in each row 2 times.
i.e. 42 + 42 = 84
OR
we can say the following:
Total number of yellow corns planted in the garden = Number of rows of yellow corn [tex]\times[/tex] Number of plants in each row
[tex]\Rightarrow 2 \times 42\\\Rightarrow 84[/tex]
To find the total number of white corns planted in the garden, we need to add the number of plants in each row 20 times.
i.e. 42 + 42 + 42 + ....... + 20 times
OR
we can say the following:
Total number of white corns planted in the garden = Number of rows of white corn [tex]\times[/tex] Number of plants in each row
[tex]\Rightarrow 20 \times 42\\\Rightarrow 840[/tex]
Hence, there are a total of 84 yellow corns and 840 white corns planted in the garden.

Ruth has 12 feet of ribbon.
She uses 7 feet of it for a craft project and gives 28 inches of it to her sister.
How many inches of ribbon does she have left?
Enter your answer in the box.
Answer:
See I don't know the answer but I did another one like this if it doesn't help you can report it no problem
Step-by-step explanation:
There are 2 different ways you can solve this problem and you'll get the same answer.
To help you visualize what you have to do, it might be easiest to translate your problem to a unit that easier to use.
Since you only have a ribbon 5 feet long, but you must cut it into 6 pieces, you know it won't even be 1 foot long.
One way to solve the problem would be to translate your 5-foot ribbon into a ribbon divided into inches.
1 foot = 12 inches
To find out how many inches long your ribbon is, you'll need to multiply the number of feet by 12.
Once you know that, then you can more easily divide it by 6. This will tell you how many inches each ribbon is.
Careful! the answer is to be put into feet so once you know how many inches long the ribbon is, you must then divide by 12 to get the correct answer in feet. Don't forget to round to the nearest tenth.
Another way to solve the problem is to simply divide the 5 feet by the number 6 and then round your number to the nearest tenth. It may be harder to visualize the answer this way, but you will get the same answer as if you translated your ribbon into inches and then divided by 12.
Good luck! I hope this helps!
32 inches of ribbon does she have left.
What is Unit Conversion?Unit conversion is a multi-step process that includes rounding, selecting the appropriate number of significant digits, and multiplying or dividing by a numerical factor.
We have,
Total length of Ribbon = 12 feet
After using 7 feet the remaining left
= 12 - 7
= 5 feet
Now, She gave 28 inches to her sister then the ribbon left
= 5 feet - 28 inches
= 60 inches - 28 inches
= 32 inches
= 2.66667 feet

How many quarts of peanut oil worth 19 cents a quart must be mixed with 100 quarts worth 25 cents a quart to produce a mixture which will be worth 24 cents a quart?
Answer: 20 quarts of peanut oil worth 19 cents a quart must be mixed.
Step-by-step explanation:
Let x represent the number of quarts of peanut oil worth 19 cents a quart that would be in the mixture.
The total number of quarts in the mixture would be x + 100
The cost of the x quarts would be x × 19 = 19x cents
The cost of 100 quarts of the other peanut oil would be 25 × 100 = 2500 cents
The cost of the mixture would be
24(x + 100) = 24x + 2400
Therefore, the equation would be
19x + 2500 = 24x + 2400
24x - 19x = 2500 - 2400
5x = 100
x = 100/5

The base is 6x = 35.8
The side is 3x = 17.9
Step-by-step explanation:
We can use the pythagorean theorem
a^2 + b^2 = c^2
(6x)^2 +(3x)^2 = 40^2
36x^2 + 9x^2 = 1600
Combine like terms
45x^2 = 1600
Divide each side by 45
45x^2 /45 =1600/45
x^2 =35.555555555
Take the square root of each side
sqrt(x^2) = sqrt(35.555555555)
x =5.96284794 = 6.0
The base is 6x = 6*5.9628479 =35.77708 = 35.8
The side is 3x = 3*5.9628479 =17.88854382= 17.9
Answer:
x = 6.0
3x = 17.9
6x = 35.8
Step-by-step explanation:
Using pythagoras theorem
40² = (3x)² + (6x)²
1600 = 9x² + 36x²
1600 = 45x²
x² = 320/9
x = 5.96284794
3x = 17.88854382

A fish bowl contains blue, green and red plastic fish. When a fish is picked out at random, the probability of it being blue is 0.7 and the probability of it being green is 0.2. A prize is given if a red fish is picked out. What is the probability of Matt picking a red fish? (Give your answer as a decimal.) There are 60 fish in the fish bowl. How many of the fish are red?
Answer:
0.1 probability of Matt picking a red fish
6 of the fish are red.
Step-by-step explanation:
We have these following probabilities:
70% = 0.7 probability that the fish is blue.
20% = 0.2 probability that the fish is green.
p probability that the fish is red.
The sum of all these probabilities is 100% = 1. So
0.7 + 0.2 + p = 1.
p = 0.1
0.1 probability of Matt picking a red fish
There are 60 fish in the fish bowl. How many of the fish are red?
n trials with p probability of sucess. The expected value is
[tex]E(X) = np[/tex]
Here we have [tex]n = 60, p = 0.1[/tex]. So
[tex]E(X) = np = 60*0.1 = 6[/tex]
6 of the fish are red.
The probability of Matt at the time of picking a red fish is 0.1.
And, The number of fish that should be red is 6.
Calculation of the probability:Since
There is a 70% probability when the fish is blue
And, 20% probability when the fish is green.
Now
Here we assume p be the probability in the case when the fish is red.
So,
Here the sum of probabilities should be 100% i.e. equal to 1.
Now
The following calculation is to be done
0.7 + 0.2 + p = 1
0.9 + p = 1
So,
p = 0.1
Now for the red one it should be
= 60 (0.1)
= 6
Hence, The probability of Matt at the time of picking a red fish is 0.1.
And, The number of fish that should be red is 6.

find all local maximum and minimum points by the second derivative test when possible y=x^4-2×^2+3
Answer:
y = x^4 - 2x^2 + 3
y' = 4x^3 - 4x
y'' = 12x^2 - 4
To find local minimum and local maximum, we find solution of y' = 0
=> 4x^3 - 4x = 0
<=>4x(x - 1)(x + 1) = 0
<=> x = 0,
substitute into y => y(0) = 0 - 0 + 3 = 3 => A(0, 3)
substitute into y'' => y''(0) = 0 - 4 = -4 < 0 => A(0, 3) is a maximal
<=> x = 1,
substitute into y => y(1) = 1 - 2 + 3 = 2 => B(1, 2)
substitute into y'' => y''(1) = 12 - 4 = 8 > 0 => B(1, 2) is a minimal
<=> x = -1,
substitute into y => y(-1) = 1 - 2 + 3 = 2 => C(-1, 2)
substitute into y'' => y''(-1) = 12 - 4 = 8 > 0 => C(-1, 2) is a minimal

Avoiding an accident while driving can depend on reaction time. Suppose that reaction time, measured from the time the driver first sees the danger until the driver gets his/her foot on the brake pedal, is approximately symmetric and mound-shaped with mean 1.9 seconds and standard deviation 0.12seconds. Use the 68-95-99.7 rule to answer the following questions.What percentage of drivers have a reaction time more than 2.14 seconds?%What percentage of drivers have a reaction time less than 1.78 seconds?%What percentage of drivers have a reaction time less than 2.02 seconds?%
Answer:
2.5% of drivers have a reaction time more than 2.14 seconds
16% of drivers have a reaction time less than 1.78 seconds
84% of drivers have a reaction time less than 2.02 seconds
Step-by-step explanation:
The Empirical Rule(68-95-99.7 rule) states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.
In this problem, we have that:
Mean = 1.9s
Standard deviation = 0.12
What percentage of drivers have a reaction time more than 2.14 seconds?
2.14 = 1.9 + 2*0.12
So 2.14 is two standard deviations above the mean.
Of the 50% of the measures above the mean, 95% are within 2 standard deviations of the mean, so, below 2.14. The other 5% is above.
0.05*0.5 = 0.025
2.5% of drivers have a reaction time more than 2.14 seconds
What percentage of drivers have a reaction time less than 1.78 seconds?
1.78 = 1.9 - 0.12
So 1.78 is one standard deviation below the mean.
Of the 50% of the measures that are below the mean, 68% are within one standard deviation of the mean, that is, greater than 1.78.
100 - 68 = 32
0.32*50 = 0.16
16% of drivers have a reaction time less than 1.78 seconds
What percentage of drivers have a reaction time less than 2.02 seconds?
2.02 = 1.9 + 0.12
So 2.02 is one standard deviation above the mean.
Of the measures that are below the mean, all are below 2.02.
Of those that are above, 68% are below 2.02.
0.5 + 0.68*0.5 = 0.84
84% of drivers have a reaction time less than 2.02 seconds
The percentage of drivers have a reaction is :
-2.5% of drivers have a reaction time more than 2.14 seconds
-16% of drivers have a reaction time less than 1.78 seconds
-84% of drivers have a reaction time less than 2.02 seconds
"68-95-99.7 rule"Answer 1:
The percentage of drivers have a reaction time more than 2.14 seconds is :2.14 = 1.9 + 2*0.12
So 2.14 is two standard deviations above the mean.Of the 50% of the measures above the mean, 95% are within 2 standard deviations of the mean, so, below 2.14. The other 5% is above.0.05*0.5 = 0.0252.5% of drivers have a reaction time more than 2.14 seconds
Answer 2:
The percentage of drivers have a reaction time less than 1.78 seconds is :1.78 = 1.9 - 0.12
So, 1.78 is one standard deviation below the mean.Of the 50% of the measures that are below the mean, 68% are within one standard deviation of the mean, that is, greater than 1.78.100 - 68 = 320.32*50 = 0.1616% of drivers have a reaction time less than 1.78 seconds.
Answer 3:
The percentage of drivers have a reaction time less than 2.02 seconds :2.02 = 1.9 + 0.12
So, 2.02 is one standard deviation above the mean.Of the measures that are below the mean, all are below 2.02.Of those that are above, 68% are below 2.02.0.5 + 0.68*0.5 = 0.8484% of drivers have a reaction time less than 2.02 seconds
