Answer:
( x+1, y+5 )
Step-by-step explanation:
x+1 because adding 1 to the x coordinate would shift it over 1
y+5 because adding 5 to the y coordinate would shift it up 5
Formula for g(x) is g(f(x)) = ( x+1, y+5 )
What is graph?
A graph can be defined as a pictorial representation or a diagram that represents data or values.
Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.
For example, If shift up by 1 unit, add 1 to function
If shift down by 4 units, subtract 4 from function
x+1 because adding 1 to the x coordinate would shift it over 1
y+5 because adding 5 to the y coordinate would shift it up 5
g(f(x)) = ( x+1, y+5 )
Hence, formula for g(x) is g(f(x)) = ( x+1, y+5 )

Step-by-step explanation:
On discovering that his family has a 75% risk of heart attack, James took a treadmill test to check his own potential of having a heart attack. The doctors told him that the reliability of the stress test is 70%. What is the probability that James will not have a heart attack and that the test predicts he will?
Answer: The required probability is 0.4375.
Step-by-step explanation:
Since we have given that
Probability of having risk of heart attack = 75%= 0.75
Probability of having reliability of the stress test = 70%
Probability of not having risk of heart attack =1-0.75 = 0.25
Probability of not having reliability of the stress test = 1-0.70 = 0.30
So, the probability that James will not have a heart attack and that the test predicts he will would be :
P(not having heart attack | correct test) is given by :
[tex]=\dfrac{0.25\times 0.7}{0.25\times 0.7+0.75\times 0.3}\\\\=\dfrac{0.175}{0.175+0.225}\\\\=\dfrac{0.175}{0.4}\\\\=0.4375[/tex]
Hence, the required probability is 0.4375.
What are the zeros of f(x) = x2 + x - 12?
O A. x= -4 and x = 3
O B. x=-6 and x = 2
O c. x=-2 and x = 6
D. x = -3 and x = 4
Answer:
Ans- A
Step-by-step explanation:
When you have a quadratic like this, f(x) = [tex]x^{2}[/tex] + x - 12,
factorize it first.
Then you'll get f(x)= (x-3)*(x+4)
Finally, you set:
0= (x-3)*(x+4)
Just use the null factor law, and there you go.
x= 3 or x=-4
Have a nice day :)
The zeros of the given quadratic equation is equivalent to 3 and -4. Option A
Determining the zeros of a quadratic equationGiven the quadratic equation below:
f(x) = x² + x - 12
Factorising the expression, we will have:
f(x) = x² + 4x - 3x - 12
Factor
f(x) = (x² + 4x) - (3x + 12)
f(x) = x(x+4) - 3(x + 4)
f(x) = (x - 3)(x+4)
If f(x) = 0
(x - 3)(x+4) = 0
x = 3 and -4
Hence the zeros of f(x) = x^2 + x - 12 are 3 and -4.

1. A magazine reported 66% of all dog owners usually greet their dog before greeting their
spouse or children when they return home at the end of the workday. Researchers select 40
dog owners at random and ask them whom they greet first when returning home. The 95%
confidence interval for the proportion of owners who greet their dog first is 0.475 to 0.775.
a) Interpret the confidence interval,
b) Calculate the point estimate and margin of error used to create this confidence interval,
c) Based on the confidence interval, is it plausible that the true proportion of all owners whi
greet their dog first is 66%? Explain.
Answer:
(a) There is 95% confidence that the true proportion of dog owners who greet their dogs first is between 0.475 and 0.775.
(b) The point estimate is 0.625. The margin of error is 0.15.
(c) It is plausible that the true proportion of all owners who greet their dog first is 66%.
Step-by-step explanation:
The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval. Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.
In statistic, point estimation comprises of the use of sample data to estimate a distinct data value (known as a point estimate) which is to function as a "best guess" or "best estimate" of an unidentified population parameter. The point estimate of the population mean (µ) is the sample mean ([tex]\bar x[/tex]).
The (1 - α)% confidence interval for population proportion is:
[tex]CI=\hat p\pm z_{\alpha/2}\times \sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
The margin of error for this interval is:
[tex]MOE=\frac{UL-LL}{2}[/tex]
For the hypothesis test, if the confidence interval consist of the null value of the parameter then the null hypothesis is accepted or else rejected.
The 95% confidence interval for the population proportion of owners who greet their dog first is,
CI = (0.475, 0.775)
(a)
The 95% confidence interval for the population proportion, (0.475, 0.775), implies that there is a 0.95 probability that the true proportion of dog owners who greet their dogs first is between 0.475 and 0.775.
Or, there is 95% confidence that the true proportion of dog owners who greet their dogs first is between 0.475 and 0.775.
(b)
The point estimate of the population proportion (p) is the sample mean ([tex]\hat p[/tex]).
Compute the point estimate from the 95% confidence interval as follows:
Point estimate = (UL + LL)/2
[tex]=\frac{0.775+0.475}{2}\\=0.625[/tex]
The point estimate is 0.625.
Compute the margin of error as follows:
[tex]MOE=\frac{UL-LL}{2}=\frac{0.775-0.475}{2}=0.15[/tex]
The margin of error is 0.15.
(c)
The hypothesis to test whether the proportion of all owners who greet their dog first is 66% is:
H₀: The proportion of all owners who greet their dog first is 66%, i.e. p = 0.66
Hₐ: The proportion of all owners who greet their dog first is not 66%, i.e. p ≠ 0.66.
The 95% confidence interval for the population proportion of owners who greet their dog first is,
CI = (0.475, 0.775)
The 95% confidence interval consists of the null value, i.e. p = 0.66.
The null hypothesis was failed to rejected.
Thus, it is plausible that the true proportion of all owners who greet their dog first is 66%.

there are 25 acres of land on a farm. the owners planted corn on 68 percent of the land. on how many acres did they not plant corn?
Answer:
8 acres of land they did not plant the corn.
Step-by-step explanation:
GIven:
There are 25 acres of land on a farm.
The owners planted corn on 68 percent of the land.
Now, to find the acres they did not plant the corn.
Total acres of land on the farm = 25 acres.
Rate of land owners planted the corn = 68%.
Now, to get the acres of land owners planted the corn:
[tex]68\%\ of\ 25\\\\=\frac{68}{100} \times 25\\\\=0.68\times 25\\\\=17\ acres.[/tex]
Thus, 3.4 acres of land owners planted the corn.
Now, to get the acres land owners did not planted the corn we subtract the acres of land owners planted the corn from the total acres of land:
[tex]25\ acres-17\ acres\\\\=8\ acres.[/tex]
Therefore, 8 acres of land they did not plant the corn.

Which graph represents the compound inequality?
n < –2 or n ≥ 4
The third number line represents the compound inequality n < –2 or n ≥ 4.
What is Number system?A number system is defined as a system of writing to express numbers.
The given compound inequality is n < –2 or n ≥ 4
We can use a combination of a less than (<) symbol and a greater than or equal to (≥) symbol to represent the inequality.
The third number line represents the inequality n < –2 or n ≥ 4.
The less than symbol indicates that n must be less than -2, while the greater than or equal to symbol indicates that n must be greater than or equal to 4.
The open circle at -2 indicates that n is not included in the solution set for n < -2,
The closed circle at 4 indicates that n is included in the solution set for n ≥ 4.
Hence, third number line represents the compound inequality n < –2 or n ≥ 4.

2.34 x 10^65 + 9.2 x10^66
Answer:
9.434 X 10^66
Step-by-step explanation:
2.34 X 10^65 + 9.2 X 10^66 (First, you have to manipulate the exponents to bring them to the same index, i.e. the same power)
We can say that 2.34 X 10^65 = 0.234 X 10^66
Now that the indexes are equivalent, we can proceed to add the two bases together.
0.234 X 10^66 + 9.2 X 10^66
= (0.234 + 9.2) X 10^66
= 9.434 X 10^66
The sum of [tex]\(2.34 \times 10^{65}\)[/tex]and [tex]\(9.2 \times 10^{66}\)[/tex] is[tex]\(9.434 \times 10^{66}\)[/tex]
When adding numbers in scientific notation, it's crucial to align their exponents. In the case of[tex]\(2.34 \times 10^{65}\)[/tex] and [tex]\(9.2 \times 10^{66}\),[/tex] they don't initially share the same exponent. To rectify this, we need to adjust the first number.
First, express[tex]\(2.34 \times 10^{65}\)[/tex]as [tex]\(0.234 \times 10^{66}\)[/tex], moving the decimal point one place to the left. Now, both numbers are in the form[tex]\(A \times 10^{66}\),[/tex]making them compatible for addition.
Next, add the coefficients:[tex]\(0.234 + 9.2 = 9.434\).[/tex]
So, the result is[tex]\(9.434 \times 10^{66}\).[/tex] This number is significantly larger than either of the original numbers. In essence, we're combining a quantity in the tens (0.234) with one in the tens of billions (9.2), resulting in a massive number in the tens of billions of billions (9.434) times 10 raised to the power of 66.
In practical terms, this means that if you were to multiply[tex]\(2.34 \times 10^{65}\)[/tex]by 10 and then add[tex]\(9.2 \times 10^{66}\)[/tex]to it, you would have [tex]\(9.434 \times 10^{66}\)[/tex] as your final answer. This demonstrates the remarkable flexibility and ease of handling extremely large numbers using scientific notation.

Write a polynomial f (x) that satisfies the given conditions. Polynomial of lowest degree with zeros of -3 (multiplicity 3) 2(multiplicity 1)and with f(0)=270 .
Final answer:
To write a polynomial f(x) with specified zeros and a value for f(0), we first express the polynomial in its factored form, then solve for the coefficient using the given f(0) value. The resulting polynomial is f(x) = -5(x + 3)^3(x - 2).
Explanation:
To write a polynomial f(x) of the lowest degree with zeros of -3 (multiplicity 3) and 2 (multiplicity 1), we use the fact that zero of multiplicity m means the factor corresponding to that zero will appear m times in the factored form of the polynomial. Given these zeros, the polynomial in its factored form is:
f(x) = a(x + 3)^3(x - 2)
We are also given that f(0) = 270. We can use this information to find the value of a:
f(0) = a(0 + 3)^3(0 - 2) = 270
a = 270 / [(-2)(3)^3]
a = 270 / (-54)
a = -5
Now we can write the polynomial with the determined value of a:
f(x) = -5(x + 3)^3(x - 2)
This is the polynomial of the lowest degree that meets the given conditions.

Peter bought 4 1/ 2 ft of cable wire. The cable wire cost $1.80 a foot. How much did Peter pay for the cable wire? A student solved the problem this way. 41 2 feet =4.5 feet Let n represent the amount Peter paid for the cable wire. n=4.5×$1.80 n=$8.10 Peter paid $8.10 for the cable wire. Use a similar strategy to solve this problem. Bobby bought 35 12 ft of red ribbon and 51 12 ft of yellow ribbon. Ribbon costs $1.20 a foot. How much did Bobby spend on ribbon?
he payed 8.10$
bobby wasted 14.4 on the red ribbon
bobby wasted 6134.4 on yellow ribbon
together he wasted 6148.8
Answer:
$ 8.1
Step-by-step explanation:
To find 4 1/2 ft of cable wire you need to find what one foot of cable wire is which is $1.80.
So now add $1.80 four times:
1.80 + 1.80 + 1.80 + 1.80 = 7.20
It will cost $7.20 for four feet of cable wire
Now you have to do a half of $ 1.80
1.8 / 2 = 0.90
Now add 7.2 and 0.90 together
7.2 + 0.9 = 8.10
So Peter would need to buy $ 8.10 of cable wire for 4 1/2 ft.

Here are three systems of equations. Which method (graphing, substitution, elimination) would you choose to solve and why. Use each method only once.
System #1 System #2 System #3
2x + 3y = 12 y = 2x +1 x = 2y + 5
4x + 3y = 18 y =-3x -2 x + 3y = 25
System #1
2x + 3y = 12 and 4x + 3y = 18
I'd use elimination on this one; we subtract equations and the 3y disappears,
2x = 6
x = 3
3y = 18-4x = 18 - 4(3) = 18 = 12 = 6
y = 2
System #2
y = 2x +1 and y =-3x -2
Here I'd use elimination; we have two things equal to y, we eliminate y by setting the right sides equal to each other,
2x + 1 = -3x - 2
5x = -3
x = -3/5
y = 2x+1 = -1/5
check y=-3x -2 = 9/5 - 10/5 = -1/5, good
System #3
x = 2y + 5 and x + 3y = 25
Here I'd use substitution. The first equation is for x in terms of y; if we substitute it into the second equation we'll just have an equation in y.
(2y + 5) +3y = 25
5y + 5 =25
5y = 20
y = 4
x = 2y+5 = 13
