Maximum height:
__ meters
Time:
__ seconds
Answers
Answer:
Maximum height: 33.7 meters
Time: 1.7 seconds
Step-by-step explanation:
Suppose we have a quadratic equation in the following format:
[tex]f(t) = at^{2} + bt + c[/tex]
In a is negative, the maximum point of the function happens at the time of
[tex]t_{v} = -\frac{b}{2a}[/tex]
And it's value is: [tex]f(t_{v})[/tex]
In this question:
[tex]f(t) = -4.9t^{2} + 17t + 19[/tex]
So [tex]a = -4.9, b = 17, c = 19[/tex]
The time of the maximum height is:
[tex]t_{v} = -\frac{b}{2a} = -\frac{17}{2*(-4.9)} = 1.7[/tex]

c) What was Jim's height above the ground after 40 minutes?
d) How many minutes did it take to reach the ground?
Answers
Answer:
Step-by-step explanation:
A) y = -20x + 2500
The above equation is written in slope intercept form - y=mx+b - the y int. is 2500, while the rate of change, aka the slope, is -20 feet per minute.
B) (0,2500) (1,2480) (2,2460) (3,2440) (4,2420)
For this question just plug in the x values 0 to 4 into the equation above. For example -20(0) +2500 = 2500
C) 1700 feet above the ground
Plug the number 40 into the equation above. -20(40) + 2500 = 1700
D) 125 minutes
The y-int. represents the time it takes him to reach the ground, this means you can set the equation equal to zero and solve to find the answer.
0 = -20x + 2500
subtract 2500 from both sides
-2500 = -20x
divide -20 from both sides
125 = x

A random sample of 20 inhabitants was selected from the community and each person was asked he/she will vote for party A in an impending election. This follows a Binomial distribution, what is the probability that:
(i) exactly two persons will vote for party A?
(ii) at least three persons will vote for party A?
(iii) fewer than two persons will vote for party A?
Answers
Answer:
i) [tex]P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669[/tex]
ii) [tex]P(X=0)=(20C0)(0.25)^0 (1-0.25)^{20-0}=0.00317[/tex]
[tex]P(X=1)=(20C1)(0.25)^1 (1-0.25)^{20-1}=0.0211[/tex]
[tex]P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669[/tex]

iii) [tex]P(X <2)= 0.00317+ 0.0211= 0.02427[/tex]
Step-by-step explanation:
Let X the random variable of interest "number of inhabitants of a community favour a political party', on this case we now that:
[tex]X \sim Binom(n=20, p=0.25)[/tex]
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]
Part i
We want this probability:
[tex]P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669[/tex]
Part ii
We want this probability:
[tex]P(X\geq 3)[/tex]
And we can use the complement rule and we have:
[tex]P(X\geq 3) = 1-P(X<3)= 1-P(X \leq 2) =1- [P(X=0) +P(X=1) +P(X=2)][/tex]
And if we find the individual probabilites we got:
[tex]P(X=0)=(20C0)(0.25)^0 (1-0.25)^{20-0}=0.00317[/tex]
[tex]P(X=1)=(20C1)(0.25)^1 (1-0.25)^{20-1}=0.0211[/tex]
[tex]P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669[/tex]
And replacing we got:
[tex] P(X \geq 3) = 1- [0.00317+0.0211+0.0669]= 0.90883[/tex]
Part iii
We want this probability:
[tex] P(X <2)= P(X=0) +P(X=1)[/tex]
And replacing we got:

what number is to be multiplied with 1/3 to get 1/21
Answers
Answer:
1/7
Step-by-step explanation:
Since we do not know the number let us use the alphabet A to represent the unknown number
A × 1/3= 1/21
A/3= 1/21
Cross multiply both sides
A×21= 3×1
21A= 3
Divide both sides by the coefficient of A which is 21
21A/21=3/21
A=1/7
Hence the unknown number is 1/7
Answer:
The number to multiply with 1/3 to get 1/21 is 1/7.
Step-by-step explanation:
The question wants us to find the number you can multiply with 1/3 to get 1/21. The number is unknown but when you multiply that unknown number by 1/3 your answer should be 1/21.
Let
the number to be multiplied with = a
Therefore,
1/3 × a = 1/21
a/3 = 1/21
cross multiply
21a = 3
divide both sides by 21
a = 3/21
a = 1/7
The number to multiply with 1/3 to get 1/21 is 1/7.

$1,780.75?
Answers
Answer:
Average income of Eric for the remaining 8 months = [tex]\$1946[/tex]
Step-by-step explanation:
Given: Average income of Eric for the first 4 months of the year is equal to $1,450.25
To find: average income for the remaining 8 months so that his average income for the year is $1,780.75
Solution:
Average income = Total income for the year/Total number of months
Average income of Eric for the first 4 months = $1,450.25
So,
Total income of Eric for the first 4 months = 1,450.25 × 4 = 5801
Let x denotes total income of Eric for the remaining 8 months
Total income for the year = 5801 + x
Therefore,
Average income for the year = [tex]\frac{5801+x}{12}[/tex]
Also, average income for the year is $1,780.75
[tex]1780.75=\frac{5801+x}{12}\\1780.75\times 12=5801+x\\21369=5801+x\\21369-5801=x\\15568=x[/tex]
Total income of Eric for the remaining 8 months = $15568
Average income of Eric for the remaining 8 months = [tex]\frac{15568}{8}=\$1946[/tex]

fouthers (out the coutlier)
Answers
Answer:
102
Step-by-step explanation:
We must calculate the value of z for each value and then compare each one and thus manage to see what is an outlier, we know that z is equal to:
z = (x - m) / sd
where x is the value to evaluate, m the mean and sd the standard deviation. Now we have to:
For x = 148:
z = (148 - 128.5) /8.2
z = 2.37
For x = 102:
z = (102 - 128.5) /8.2
z = -3.23
For x = 152:
z = (152 - 128.5) /8.2
z = 2.86
The value of this is generally between -3.09 and 3.09, so when x is 102, it goes out of range of the value of z, which means that this is the outlier.

Explain how to find the relationship between two quantities, x and y, in a table. How can you use the relationship to calculate the missing values in the table?
Answers
Explanation:
In general, for arbitrary (x, y) pairs, the problem is called an "interpolation" problem. There are a variety of methods of creating interpolation polynomials, or using other functions (not polynomials) to fit a function to a set of points. Much has been written on this subject. We suspect this general case is not what you're interested in.
__
For the usual sorts of tables we see in algebra problems, the relationships are usually polynomial of low degree (linear, quadratic, cubic), or exponential. There may be scale factors and/or translation involved relative to some parent function. Often, the values of x are evenly spaced, which makes the problem simpler.
Polynomial relations
If the x-values are evenly-spaced. then you can determine the nature of the relationship (of those listed in the previous paragraph) by looking at the differences of y-values.
"First differences" are the differences of y-values corresponding to adjacent sequential x-values. For x = 1, 2, 3, 4 and corresponding y = 3, 6, 11, 18 the "first differences" would be 6-3=3, 11-6=5, and 18-11=7. These first differences are not constant. If they were, they would indicate the relation is linear and could be described by a polynomial of first degree.
"Second differences" are the differences of the first differences. In our example, they are 5-3=2 and 7-5=2. These second differences are constant, indicating the relation can be described by a second-degree polynomial, a quadratic.
In general, if the the N-th differences are constant, the relation can be described by a polynomial of N-th degree.
You can always find the polynomial by using the given values to find its coefficients. In our example, we know the polynomial is a quadratic, so we can write it as ...
y = ax^2 +bx +c
and we can fill in values of x and y to get three equations in a, b, c:
3 = a(1^2) +b(1) +c
6 = a(2^2) +b(2) +c
11 = a(3^2) +b(3) +c
These can be solved by any of the usual methods to find (a, b, c) = (1, 0, 2), so the relation is ...
y = x^2 +2

Exponential relations
If the first differences have a common ratio, that is an indication the relation is exponential. Again, you can write a general form equation for the relation, then fill in x- and y-values to find the specific coefficients. A form that may work for this is ...
y = a·b^x +c
"c" will represent the horizontal asymptote of the function. Then the initial value (for x=0) will be a+c. If the y-values have a common ratio, then c=0.

Finding missing table values
Once you have found the relation, you use it to find missing table values (or any other values of interest). You do this by filling in the information that you know, then solve for the values you don't know.
Using the above example, if we want to find the y-value that corresponds to x=6, we can put 6 where x is:
y = x^2 +2
y = 6^2 +2 = 36 +2 = 38 . . . . (6, 38) is the (x, y) pair
If we want to find the x-value that corresponds to y=27, we can put 27 where y is:
27 = x^2 +2
25 = x^2 . . . . subtract 2
5 = x . . . . . . . take the square root*
_____
* In this example, x = -5 also corresponds to y = 27. In this example, our table uses positive values for x. In other cases, the domain of the relation may include negative values of x. You need to evaluate how the table is constructed to see if that suggests one solution or the other. In this example problem, we have the table ...
(x, y) = (1, 3), (2, 6), (3, 11), (4, 18), (__, 27), (6, __)
so it seems likely that the first blank (x) will be between 4 and 6, and the second blank (y) will be more than 27.
Here is your answer | To determine the relationship between quantities, you must determine what to do to the x-values to make them into y-values. The correct operation must turn every x-value into the corresponding y- value in the table. Once you know the relationship, you can use the same operation on all of the x-values that have unknown y-values.

Answer:
volume = 75 cubic yards
Step-by-step explanation:
Base is 3×5 or 15 yd²
110-15-15=b×3×2+b×5×2
80=6b+10b
80=16b
Divide both sides by 16
b=5
The height of the rectangular prism is 5 yards
Now the volume is l×w×h
3×5×5=
75 yd³ or 75 cubic yards
Answer:
Volume = 75 yards³
Step-by-step explanation:
Surface Area = 110 yards²
But
Surface area = 2(wl+lb+bw) --(1)
Where w is the width , l is length and b is height
L = 5 yards, w = 3 yards
Putting in (1)
110 = 2{(3)(5)+(5)b+3b}
110 = 2(15+5b+3b)
110 = 2(15+8b)
110 = 30+16b
16b = 110-30
16b = 80
Dividing both sides by 18
b = 5
Now
Volume of rectangular prism = wlb
Where w is width, l is length and b is height
= (5)(3)(5)
= 75 yards³
a bucket that holds 5 1/4 gallons of water is being used to fill a tub that can hold 34 1/8 gallons. How many buckets will be needed to fill the tub?
Answers
The answer is 6 1/2 buckets.
What is did was turn the fractions into decimals to make it easier.
So the ratio is 5.25 gallons per bucket. I divided 34 1/8 by 5 1/4 in decimal form (34.125/5.25) and got 6.5
So therefore, the answer is 6 1/2 buckets of water is needed ti fill up the tub.
