Answer:
The coordinates of the center of the hyperbola are (1,-3)
Step-by-step explanation:
Equation of a hyperbola:
The equation of a hyperbola with center [tex](x_0,y_0)[/tex] is given by:
[tex]\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1[/tex]
In this question, we have that:
[tex]-x_0 = -1 \rightarrow x_0 = 1[/tex]
[tex]-y_0 = 3 \rightarrow y_0 = -3[/tex]
The coordinates of the center of the hyperbola are (1,-3)

G and H are mutually exclusive events. • P(G) = 0.5 • P(H) = 0.2
Answer:
[tex]P(G\ or\ H) = 0.7[/tex]
Step-by-step explanation:
Given
[tex]P(G) = 0.5[/tex]
[tex]P(H) = 0.2[/tex]
Required [Missing from the question]
[tex]P(G\ or\ H)[/tex]
Because the events are mutually exclusive, we use:
[tex]P(G\ or\ H) = P(G) + P(H)[/tex]
So, we have:
[tex]P(G\ or\ H) = 0.5 + 0.2[/tex]
[tex]P(G\ or\ H) = 0.7[/tex]

When you see average rate of change what should you automatically think of
Answer:
Steady rate
Step-by-step explanation:
It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
Jamie buys a new fish tank, which is 55 cm long, 25 cm wide and 40 cm high. He needs
to fill the tank with water that has to be 35 cm deep. How much water does he need to fill
the tank, if 1000 cm = 1 litre? Give your answer rounded to the nearest litre.
Answer:
0.155litre
Step-by-step explanation:
55+25+40+35=155cm
100Cm=1litre
155cm_ ?
155cm×1litre/1000cm
0.155Litre

Answer:
(a)
[tex]\begin{array}{cccccccc}x & {0} & {1} & {2} & {3} & {4}& {5} & {6} \ \\ {P(x)} & {0} & {4} & {8} & {12} & {16}& {20} & {24} \ \end{array}[/tex]
(b)
[tex]P(x) = 4x[/tex]
(c)
See attachment for graph
Step-by-step explanation:
Given
P(x) = Perimeter of square
Solving (a): Complete the table
The perimeter of a square is:
[tex]P =4x[/tex]
so, the table will be completed by multiplying each value of x by 4.
So, we have:
[tex]\begin{array}{cccccccc}x & {0} & {1} & {2} & {3} & {4}& {5} & {6} \ \\ {P(x)} & {0} & {4} & {8} & {12} & {16}& {20} & {24} \ \end{array}[/tex]
Solving (b): The equation
This has already been stated in (a)
[tex]P(x) = 4x[/tex]
Solving (c): The graph

If the given figure is rotated 180° around the origin, what are the new coordinates of point Z?
please I really need help with this.
Answer:
New coordinates of the point Z are (-6, 9)
Step-by-step explanation:
If a point (x, y) is rotated 180° about the origin, coordinates of the image point is given by the rule,
(x, y) → (-x, -y)
Coordinates of the vertex Z → (6, -9)
Following the same rule,
Z(6, -9) → Z'(-6, 9)
Therefore, coordinates of the new (image) point will be (-6, 9).
Melanie invested $9,800 in an account paying an interest rate of 4 1 2 4 2 1 % compounded quarterly. Amelia invested $9,800 in an account paying an interest rate of 4 3 4 4 4 3 % compounded continuously. After 20 years, how much more money would Amelia have in her account than Melanie, to the nearest dollar?
After 20 years, the amount of Money Amelia would have more than Melanie would be $181,551.37.
What is the future value of Melanie's account?The formula for calculating future value:
FV = P (1 + r) nm
FV = Future value P = Present value R = interest rate = 4 1/2 ÷ 4 = 1.125%m = number of compounding = 4N = number of years9800(1 + 0.0125)^80 = 23,983.29
What is the future value of the amount in Amelia's account?the formula for calculating future value when there is continuous compounding is : A x e^r x N
Where:
A= amount e = 2.7182818 N = number of years r = interest rate9800 e^0.0475 x 20 = 205,534.66
Difference = 205,534.66 - 23,983.29 = $181,551.37

Henry runs business
preparing peoples taxes.
He has monthly expenses
off $25.30 for printer ink
and $52 for advertising.
So far his revenue for the
month has been $3,456,
what is the profit that he
had made?
Answer:
3,378.70
Step-by-step explanation:
First, find the total amount Henry spends a month. 25.30 for printer ink and 52 for advertising. 25.30+52=$77.30.
Subtract what he has spent from what he has made.
3,456-77.30=3,378.70
That is his profit.

Mary Jo spends $2,300 to buy stock in two companies. She pays $19 a share to one of the companies and $24 a share to the other. If she ends up with a total of 100 shares, how many shares did she buy at $19 a share and how many did she buy at $24 a share?
She bought ____ shares at $19 and ___ shares at $24.
Answer:
She bought _20___ shares at $19 and _80__ shares at $24.
Step-by-step explanation:
x + y = 100
19x + 24y = 2300
-19x - 19y = -1900
5y = 400
y = 80
x + 80 = 100
x = 20
She bought _20___ shares at $19 and _80__ shares at $24.

An agricultural researcher wishes to see if a kelp extract prevents frost damage on tomato plants. two similar small plots are going to be planted with the same variety of tomato. plants in both plots are treated identically, expect the plants on plot 1 are going to be sprayed weekly with a kelp extract while the the plants in a plot 2 are not. let p1 and p2 be the actual proportion of all tomatoes of this variety that would experience crop damage under the kelp and no kelp treatments, respectively, when grown under conditions similar to those in the experiment. which of the following results would indicate that a difference exists between the two treatments?
(a) the 95% confidence interval for p1-p2 is (-0.279, -0.035).
(b) the 95% confidence interval for p1-p2 is (-0.279, 0.035)
(c) the 95% confidence interval for p1-p2 is (0.0279, 0.350)
(d) all of the above
(e) only (a) and (c)
Answer:
(E). only (a) and (c)
Step-by-step explanation:
H0 : p1 - p2 = 0
H1 : p1 - p2 ≠ 0
To indicate that difference exists between the two treatments, then we must reject the null and confidence interval must show that the difference between the two treatment is significant.
In other to use confidence interval to test for significance ; Intervals which do not contain 0 implies that difference exists and hence, the difference is significant.
The interval Given by : (-0.279, -0.035) is significant as the interval does not contain 0.
The interval Given by : (0.279, 0.035) is significant as the interval does not contain 0.
The interval Given by : (-0.279, 0.035) is not significant as the interval contains 0.
A survey was run by a high school student in order to determine what proportion of mortgage-holders in his town expect to own their house within 10 years. He surveyed 35 mortgage holders and found that the proportion of these that did expect to own their house within 10 years is 0.51. The student decides to construct a 95% confidence interval for the population proportion. a)Calculate the margin of error that the high school student will have. Give your answer as a decimal to 2 decimal places. Margin of error
Answer:
The margin of error is of 0.17.
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 zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
He surveyed 35 mortgage holders and found that the proportion of these that did expect to own their house within 10 years is 0.51.
This means that [tex]n = 35, \pi = 0.51[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
a)Calculate the margin of error that the high school student will have.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 1.96\sqrt{\frac{0.51*0.49}{35}}[/tex]
[tex]M = 0.1656[/tex]
Rounding to 2 decimal places, the margin of error is of 0.17.

Answer:
[tex]\frac{1}{4} * 3 = \frac{3}{4}[/tex]
Because:
[tex]\frac{1}{4} * 3 = \frac{1}{4} +\frac{1}{4} + \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{4} * 3 = [\ ][/tex]
Because
[tex]\frac{1}{4} * 3 = [\ ] + [\ ] + [\ ][/tex]
Required
Fill in the box
[tex]\frac{1}{4} * 3 = [\ ][/tex]
This can be written as:
[tex]\frac{1}{4} * 3 = \frac{1* 3 }{4}[/tex]
Solve the numerator
[tex]\frac{1}{4} * 3 = \frac{3}{4}[/tex]
(b) Because
[tex]\frac{1}{4} * 3 = [\ ] + [\ ] + [\ ][/tex]
The above implies that
[tex]\frac{1}{4}[/tex] be added in 3 places
i.e.
[tex]\frac{1}{4} * 3 = \frac{1}{4} +\frac{1}{4} + \frac{1}{4}[/tex]
