Which is the equation of a hyperbola with directrices at x = ±2 and foci at (5, 0) and (−5, 0)?
Answers
The required equation of the hyperbola is expressed as
[tex]\frac{x^2}{10}- \frac{y^2}{15}=1 \\[/tex]
The standard form for calculating the equation of a parabola along the x-axis is expressed as:
[tex]\frac{(x-k)^2}{a^2}-\frac{(y-h)^2}{b^2} = 1 \ ............. 1[/tex] where:
(h, k) is the center
(k±c, h) are the foci
[tex]x=h\pm\frac{a^2}{c}[/tex] is the directrix
From the question given, we can see that foci = (±5, 0)
k±c, h = ±5, 0
k = 0
h = 0
c = 5
From the directrix,
[tex]x=h\pm\frac{a^2}{c}\\x =0\pm\frac{a^2}{5}\\\pm2 = \pm\frac{a^2}{5}\\a^2 = 10\\[/tex]
Also, we need to know that;
a²+b² = c²
10 + b² = 5²
b² = 25 - 10
b² = 15
Substituting the gotten values into the equation of a hyperbola;
[tex]\frac{(x-0)^2}{10}- \frac{(y-0)^2}{15} =1\\\frac{x^2}{10}- \frac{y^2}{15} =1\\[/tex]
This gives the required equation of the hyperbola

Lu has 13 apples. He tries to put them into 2 equal piles. One pile is bigger. How many apples does the big pile have?
Answers
Answer:
7 apples
Step-by-step explanation:
You can divide the apples by 2, but you will have a decimal. The closest you can get it without having a decimal is 7 in one pile, and 6 in the other. The pile with 7 apples is bigger.
The big pile has 7 apples because 13÷2 will leave you with a remainder so if you split 13 apples, 1 apple would be left, so then you add it to one of the piles to get 7 in one pile and 6 in the other.
You choose a tile at random from a bag containing 4 A’s, 3 B’s, and 5 C’s. You replace the first tile in the bad and then choose again. Find P(B and B)
Answers
Answer:
P(B and B) = 1/9
Step-by-step explanation:
There are 4+3+5 = 12 tiles in total
The probability of selecting a B would be 4/12=1/3
When you are replacing a B tile, planning to pick a B tile again, the total tile count doesn't change. Therefore, because the two events are independent, their probabilities are multiplied and so P(B and B) = P(B) * P(B) = 1/3 * 1/3 = 1/9

Two pizza delivery drivers compared the mean numbers of

Mean number of deliveries Mean Absolute Deviation (MAD)
Driver A

2
Driver B 20
2
Which statement about the data is true?
A. On average, driver A delivers more pizzas in one day than driver B.
O B. The mean number of deliveries for driver A is less than the mean
for driver B by 2 MADS.
OC. The MAD for driver A is less than the MAD for driver B.
O D. The mean number of deliveries for driver A is less than the mean
for driver B by 5 MADs.
Answers
Answer:
D.
Step-by-step explanation:
The difference in pizza delivered between driver A and driver B is 10 pizzas.
We can find this by doing 20-10 which is 10.
The MAD is 2.
D says that Driver A has less pizzas delivered than Driver B by 5 MADs. Since 1 MAD is 2, 5 MADs is 10.
Meaning D says that driver A delivered 10 less pizzas than Driver B, which is correct.

Marcia sells bracelets. She sells each one for $1.50. This year she spent $32.76 on supplies. At the end of the year, she made $292.74 in profit. Write an equation to represent this situation.
Answers
Answer:
$1.5b - $32.76 = $292.74
Step-by-step explanation:
Profit = total revenue - total cost
total revenue = price per unit x total unit of bracelet sold
total revenue = $1.50 x b = $1.50b
b = total units of bracelets sold
total cost = $32.76
$1.5b - $32.76 = $292.74
Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?
Answers
Answer:
There are 25 students in the class.
Step-by-step explanation:
Let the total number of students in the class= x
No. of students who passed the test = 18 = 72% of x = 72x/100
Therefore, 72x/100=18
=72x=18*100=1800
=x=1800/72= 25 students.
Hence, total number of students in the class= 25 students
