This hyperbola is centered at the
origin. Find its equation.
Foci: (-4,0) and (4,0)
Vertices: (-3,0) and (3,0)
Answer:
The equation is ( x² / 9 ) - ( y² / 7 ) = 1
Step-by-step explanation:
Given the data in question;
hyperbola is centered at the origin, this means h and k are all equals to 0.
Vertices: (-3,0) and (3,0)
Since y-coordinates are constant, this implies it is a hyperbola with horizontal transverse axis.
h - a = -3
0 - a = -3
a = 3
Foci: (-4,0) and (4,0)
h - c = -4
0 - c = -4
c = 4
we know that, for a hyperbola
c² = a² + b²
so
⇒ ( 4 )² = ( 3 )² + b²
16 = 9 + b²
b² = 16 - 9
b² = 7
So the equation for the hyperbola will be;
⇒ ( (x-h)² / a² ) - ( (y-k)² / b² ) = 1
so we substitute
⇒ ( (x-0)² / 3² ) - ( (y-0)² / 7 ) = 1
⇒ ( x² / 3² ) - ( y² / 7 ) = 1
⇒ ( x² / 9 ) - ( y² / 7 ) = 1
Therefore, The equation is ( x² / 9 ) - ( y² / 7 ) = 1

X - 3y – Z=-9
-2x + y + 2z = 3
2x + y + 3z = 8
Answer:
x = 1 y = 3 z = 1
Step-by-step explanation:
(1) x - 3y - z = -9 (2) -2x + y + 2z = 3 (3) 2x + y + 3z = 8
2x(1) 2x - 6y - 2z = -18 (2) -2x + y + 2z = 3
- 5y = -15 2y + 5z = 11
y = 3 2(3) + 5z = 11
6 + 5z = 11
5z = 5
z = 1
x - 3(3) - 1 = -9
x - 9 - 1 = -9
x - 10 = -9
x = 1

What is P(Foreign Language n Sport)?
Answer:
[tex]P(Foreign\ Language\ n\ Sport) = \frac{7}{25}[/tex]
Step-by-step explanation:
Given
See attachment for Venn diagram
Required
Determine [tex]P(Foreign\ Language\ n\ Sport)[/tex]
First, we calculate the population of the set.
This is calculated as:
[tex]Total = Sport + Foreign\ Language + None + Both[/tex]
This gives
[tex]Total = 23 + 10 + 3+14[/tex]
[tex]Total = 50[/tex]
So, the required probability is:
[tex]P(Foreign\ Language\ n\ Sport) = \frac{n(Foreign\ Language\ n\ Sport)}{Total}[/tex]
[tex]P(Foreign\ Language\ n\ Sport) = \frac{14}{50}[/tex]
14 represents the intersection between Foreign and Sport i.e. n(Foreign n Sport)
So, we have:
[tex]P(Foreign\ Language\ n\ Sport) = \frac{7}{25}[/tex]

A bottler of drinking water fills plastic bottles with a mean volume of 993 milliliters (mL) and standard deviation of 4 mL. The fill volumes are normally distributed. What proportion of bottles have volumes between 991 mL and 997 mL?
Answer:
52.38%
Step-by-step explanation:
P(991<X<997) = normalcdf(991,997,993,4) = 0.5328, therefore, about 52.38% of the bottles have volumes between 991 mL and 997 mL
The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%
Given that,
A bottler of drinking water fills plastic bottles with a mean volume of 993 milliliters (mL),
And standard deviation of 4 ml. The fill volumes are normally distributed.
We have to determine,
What proportion of bottles have volumes between 991 mL and 997 mL.
According to the question,
Mean of the drinking bottle = 993ml
[tex]\mu = 993[/tex]
And standard deviation of = 4 mL
[tex]\sigma = 4[/tex]
The proportion of bottles have volumes between 991 mL and 997 mL is,
[tex]= P (991<X<997) \\\\= P ( \dfrac{991-993}{4} <X < \dfrac{997-993}{4}) \\\\P( -0.5 < X < 1) = 0.5328 = 53.28\ percent[/tex]
Hence, The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%.

A bag of M&Ms contains 7 blue, 4 brown, 4 orange, 2 yellow, 3 red, and 3
green. Reaching into the bag, a person grabs 5 M&Ms.
What is the probability of getting 3 blues?
Answer:
0.1248 = 12.48% probability of getting 3 blues.
Step-by-step explanation:
The M&Ms are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
7 + 4 + 4 + 2 + 3 + 3 = 23 total M&Ms, which means that [tex]N = 23[/tex]
Sample of 5 means that [tex]n = 5[/tex]
7 blue means that [tex]k = 7[/tex]
What is the probability of getting 3 blues?
This is P(X = 3).
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 3) = h(3,23,5,7) = \frac{C_{7,3}*C_{16,2}}{C_{23,5}} = 0.1248[/tex]
0.1248 = 12.48% probability of getting 3 blues.

Answer:
A. 55°
Step-by-step explanation:
Complementary angles are angles that add up to give us 90°.
Since <A and <B are complementary angles, it implies that:
m<A + m<B = 90°
If m<A = 35°, therefore:
35° + m<B = 90°
Subtract 35° from each side
m<B = 90° - 35°
m<B = 55°

A researcher reported the results from a particular experiment to the scientist who conducted it. The report states that on one specific part of the experiment, a statistical test result yielded a p-value of 0.18. Based on this p-value, what should the scientist conclude?
The test was not statistically significant because 2 × 0.18 = 0.36, which is less than 0.5.
The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 18% of the time.
The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 82% of the time.
The test was statistically significant because a p-value of 0.18 is greater than a significance level of 0.05.
The test was statistically significant because p = 1 − 0.18 = 0.82, which is greater than a significance level of 0.05.

Assuming there are no leap years, what would the total 3-year cost be for a laptop that has an average lifespan of 10 years, when you purchased it for $780 and the daily cost to use it is $0.36
A $394.20
B$565.92
C$78.00
D$S1174 20
Answer:
Step-by-step explanation:
The total cost for the laptop for 3 years is $1174.20.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
Cost of the laptop when purchased = $780
Daily cost = $0.36
Number of days in 3 years = 3 × 365 = 1095 days
Cost for the laptop for 3 years = 1095 × $0.36
= $394.20
Total 3 year cost = $394.20 + $780
= $1174.20
Hence the total cost for the laptop is $1174.20.
