uppose that you live in a community that has 1,250 households. Among these households, 500 have traditional landline telephones while the remaining 750 only use cellular and / or VOIP telephones. We are going to select 100 households from your community at random without replacement. The first household selected does not have a traditional landline telephone. What is the probability that the second household selected will have a traditional landline telephone
Answer:
0.4003 = 40.03% probability that the second household selected will have a traditional landline telephone.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The first household selected does not have a traditional landline telephone.
This means that of 1250-1 = 1249 households, 500 have traditional landline telephones.
What is the probability that the second household selected will have a traditional landline telephone
500/1249 = 0.4003
0.4003 = 40.03% probability that the second household selected will have a traditional landline telephone.
In southern California, a growing number of individuals pursuing teaching credentials are choosing paid internships over traditional student teaching programs. A group of thirteen candidates for six local teaching positions consisted of seven who had enrolled in paid internships and six who enrolled in traditional student teaching programs. All thirteen candidates appear to be equally qualified, so six are randomly selected to fill the open positions. Let Y be the number of internship trained candidates who are hired.
Find the probability that two or more internship trained candidates are hired.
Answer:
0.9225 = 92.25% probability that two or more internship trained candidates are hired.
Step-by-step explanation:
Candidates are chosen without replacement, which means that we use the hypergeometric distribution to solve this question.
Hypergeometric distribution:
The probability of x sucesses 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 sucesses.
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]
Group of 13 individuals:
This means that [tex]N = 13[/tex]
6 candidates are selected:
This means that [tex]n = 6[/tex]
6 in trained internships:
This means that [tex]k = 6[/tex]
Find the probability that two or more internship trained candidates are hired.
This is:
[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]
In which
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
So
[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 = 0) = h(0,13,6,6) = \frac{C_{6,0}*C_{7,6}}{C_{13,6}} = 0.0041[/tex]
[tex]P(X = 1) = h(1,13,6,6) = \frac{C_{6,1}*C_{7,5}}{C_{13,6}} = 0.0734[/tex]
[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.0041 + 0.0734 = 0.0775[/tex]
[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.0775 = 0.9225[/tex]
0.9225 = 92.25% probability that two or more internship trained candidates are hired.
Banu will build a fence around a rectangular
30-foot-by-25-foot play area. Given that fencing costs
$4.05 per foot, how much will the fencing cost for
Banu to completely surround the play area?
Answer:
A
Step-by-step explanation:
Dimension of the rectangular fence:
Length = 30 ft
Width = 25 ft
Perimeter of the rectangular fence = 2(L + W)
= 2(30 + 25) = 2(55)
Perimeter = 110 ft
Fencing cost per foot = $4.05
Fencing cost for 110 ft = 110 × 4.05 = $445.50

Solve 6/10 times 1.7 =
Answer:
1.02 or 51/50
Step-by-step explanation:
First we convert the fraction 6/10, as a decimal
6/10 = 0.6
Then we simply multiply
1.7 × 0.6 = 1.02
Lastly we reduce
1.02 = 1 2/100 or 51/50

Dmitri wants to cover the top and sides of this box with glass tiles that are 1 cm square. How many tiles
will he need?
7 cm
14 cm
Dmitri will need
23 cm
glass tiles.
Answer:
372
Step-by-step explanation:
We are given that the dimensions of the box are,
Length = 15 cm, Width = 20 cm and Height = 9 cm.
We know that the box represents a cuboid.
Since, surface area of a cuboid = L×W + 2×L×H + 2×W×H
Thus, the surface area of the box = 15×20 + 2×15×9 + 2×20×9
i.e. Surface area = 300 + 270 + 360
i.e. Surface area = 930.
Thus, the surface area of the box is 930 cm² i.e. 9300 mm².
Further, the sides of the tiles are 5 mm and the tile represents a square.
So, the surface area of the tile = 5 × 5 = 25 mm².
This gives us that,
Number of tiles required to cover the box = = 372.
Hence, Dmitri requires 372 tiles to cover the box.

A. 95
B. 85
C. 750
D. 105
Answer:
B. 85
Step-by-step explanation:
A triangle has a total of 180 degrees.
85 + 55 = 140
140 + 40 = 180
Your answer is B. 85
The value of x is 85°
What is sum of angles of triangle ?
The sum of interior angles of a triangle are 180°
If ∠A, ∠B, ∠C are three interior angles of a triangle,
Then ∠A+∠B+∠C = 180°
What is the required angle ?Given that, Two angles of the triangle are 40° & 55°
Let, the third angle be x.
Then, Sum of angles = 180°
⇒ 40°+55°+x = 180°
⇒ x+95° = 180°
⇒ x = 180°-95°
⇒ x = 85°
The value of x = 85°

In a right triangle when a = 8 and b = 15, what is the measure of c? ill give brainlist asap HELP!!!!!
Answer: 17
Step-by-step explanation:
To answer this question you can use the Pythagorean theorem which is a^2 + b^2=c^2. Plugging in the values you get 8^2 + 15^2=c^2. 8 times 8 is 64 and 15 times 15 is 225. 64+225=289. That leaves 289=c^2. Then find the square root of both numbers which leaves you with 17=c
Answer:
[tex]\boxed {\boxed {\sf c=17}}[/tex]
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
We know that a is 8 and b is 15. We don't know the measure of c.
[tex]a=8 \\b=15[/tex]
Substitute the values into the formula.
[tex](8)^2+(15)^2=c^2[/tex]
Solve the exponents.
(8)²= 8*8=64 (15)²= 15*15=225[tex]64+225=c^2[/tex]
Add on the left side.
[tex]289=c^2[/tex]
Take the square root of both sides. This "cancels out" the exponent of 2 and isolates the variable.
[tex]\sqrt {289}=\sqrt{c^2}\\\sqrt{289}=c\\17=c[/tex]
The measure of c is 17.

X = 49
Step-by-step explanation:
The top angle that measures 126° is a mirrored version of the angle measuring (x + 77)°. The means the angle, (x + 77)°, has to measure 126°. So, to get x you have to subtract 126 by 77 and that gives you 49.
