Step-by-step explanation:
A product is composed of four parts. In order for the product to function properly in a given situation, each of the parts must function. Two of the parts have a 0.79 probability of functioning, and two have a probability of 0.83. What is the overall probability that the product will function properly?
Answer:
0.430
Step-by-step explanation:
Product has four parts :
For proper functioning, each part must function :
Let the 4 parts be:
A, B, C and D
Proper functioning probability :
A and B = 0.79
C and D = 0.83
For proper functioning :
P(A) * P(B) * P(C) * P(D)
0.79 * 0.79 * 0.83 * 0.83
= 0.42994249
= 0.430

The distance from Agnew Middle School to Baylor University is 180 kilometers. There are approximately 8 kilometers in 5 miles. Which measurement is closest to the number of miles between these schools? * 22 mi 113 mi 288 mi 175 mi
Answer:
113 miles
Step-by-step explanation:
Distance = 180 km
Number of km per mile = (8/5) = 1.6 miles
Number of miles between the schools:
Distance / Number of kilometers per mile
180km / 1.6
= 112.5 miles
= 113 miles
Distance between the schools is approximately 113 miles
Find the total surface area of a cylinder whose diameter is 28 cm and height is 11 cm.
Answer:
2199.11 (with pi)
2198 (with 3.14)
Step-by-step explanation:
A=2πrh+2πr²
A=2π(14)(11)+2π(14)²
A=2π(154)+2π(196)
A=2(483.56)+2(615.44)
A=967.12+1230.88

The radius r of the base of a cone is given by the equation r=(3V/piH)
, where V is the volume of the cone and h is the height of the cone. Find the radius of the paper cup to the nearest inch. Use 3.14 for pi .
Answer:
1 inStep-by-step explanation:
Given the expression to calculate the radius r of the base of a cone is given by the equation
r=(3V/piH)
v is the volume = 5in^3
H = 4in
pi = 3.14
Substitute
r = 3(5)/3.14(4)
r = 15/12.56
r = 1.19
r = 1in to the nearest inch

Each figure is composed of large squares and small squares. The side length of the
large square is x. Write an expression for the area of the shaded part of each figure.
Figure A
Figure B
** Please help!!
Hey, did you get the expressions for both figure A and B? If so could you pls write them down below.
9514 1404 393
Answer:
A. x² -4
B. 2x² +8
Step-by-step explanation:
The area of the larger square is the square of its side length, so is x².
A. The area of each of the smaller squares is 1² = 1. There are 4 of them, so their total area is 4×1 = 4. The shaded area is that much less than the area of the larger square, so is ...
x² - 4
__
B. The smaller squares have side length 2, so their area is 2² = 4. There are two of them, so the total area of the smaller squares is 2×4 = 8.
The two large squares have a total area of ...
2 · x² = 2x²
So, the total shaded area is ...
2x² + 8
A box is filled with 9 brown cards, 2 yellow cards, and 3 blue cards. A card is chosen at random from the box. What is the probability that it is a brown or a blue
card?
Answer:
9 / 14 for a brown , 3 / 14 for a blue
Step-by-step explanation:
1) summarize all cards 9 (brown) + 2 (yellow) + 3 (blue)= 14 cards.
2) probability depends on how many cards of a particular color, how more cards, then more probability.
3) 9 brown cards, so probability = 9 brown cards to divide all cards 14.
Shelter A has 500 beds and is 90% occupied. Shelter B is 60% occupied, the ratio of beds in Shelter A to Shelter B is 15:16
Answer:
800 bedsStep-by-step explanation:
Shelter A has 500 beds and is 90% occupied.
Number of occupied beds:
500*0.9 = 450The ratio of beds occupied in Shelter A to Shelter B is 15:16
450/x = 15/16x = 450*16/15x = 480Number of occupied beds in Shelter B is 480 which is 60% of total. Total number of beds is:
480/0.6 = 800Answer:
Answer:there are 900 beds in shelter B
Step-by-step explanation:
Shelter A has a capacity of 300 beds and is 80% occupied. This means that the number of beds in Shelter A that would be
80/100 × 300 = 0.8 × 300 = 240 beds.
Let x represent the capacity of Shelter B. Shelter B is 45% occupied. It means that number of beds in Shelter B that would be occupied is
45/100 × x = 0.45 × x = 0.45x beds.
Total occupancy of shelter A and shelter B would be
240 + 0.45x
The ratio of the occupancy of shelter A to shelter B is 16:27
Total ratio of occupancy = 16 + 27 = 43
Therefore
27/43 × (240 + 0.45x) = 0.45x
27(240 + 0.45x) = 0.45x × 43 = 19.35x
6480 + 12.15x = 19.35x
6480 = 19.35x - 12.15x = 7.2x
x = 6480/7.2 = 900

Answer:
0.30 of a book / hour or 3/10 of a book per hour.
Step-by-step explanation:
Usually I tell people to put the numbers into decimals. Unfortunately for this question, it won't work. So we have any choice but to do it with fractions.
r = amount / time
amount = 1/4
time = 5/6
r = [tex]\frac{\frac{1}{4} }{\frac{5}{6} }[/tex]
Invert the denominator and multiply
r = [tex]\frac{1}{4} * \frac{6}{5}[/tex]
r = 6 * 1 / (5*4) = 6/20 = 3/10
The answer is 3/10 of a book per hour
5/6 of an hour is almost an hour.
1/4 of a book is 0.25 of a book.
3/10 of a book is 0.30 of a book. So it looks like it is just about right.

De 40 estudiantes de undécimo grado, 14 toman clase de piano y 29 clases se violín.
a. Si cinco estudiantes toman ambas clases,¿ cuántos estudiantes no asisten a ninguna de las dos?
b. ¿cuántos estudiantes toman clase de piano o de violín?
c. cuántos estudiantes toman únicamente clases de violín?
Puedes separar los grupos en:
los que solo toman clases de piano; p
los que solo toman clases de violin: v
los que toman clases de piano y violin; 5
A) para determinar cuántos estudiantes no toman ni piano ni violin, podemos hallar el número total de estudiantes que toman clases solo de piano y los que toman solo de violín y los que toman ambas clases, de la siguiente forma:
Estudian solo piano, p = 14 - 5= 9
Estudian solo violín, v = 29 - 5 = 24
Estudian ambos: 5
Total de estudiantes que toman clases de esos instrumentos : 9 + 24 + 5 = 38
Por tanto, hay 40 - 38 = 2 estudiantes que no toman clases de piano ni violín.
B) ¿cuántos estudiantes toman clases de piano o violín?
Son los que tocan solo piano, o solo violín o ambos y los hallamos arriba: 9 + 24 + 5 = 38.
Respuesta: 38
C) ¿Cuántos estudiantes tocan solo violín?
También lo encontramos arriba: son 29 - 5 = 24
Respuesta: 24

Tickets to the play on Saturday were $40.00. On Sunday they went on sale for 15% off. How much were the discounted tickets?
a.) $32.00 a ticket
b.) $39.00 a ticket
c.) $34.00 a ticket
Answer:
C
Step-by-step explanation:
40× 15 out of 100 =6
40-6=34
Answer:
c.) $34.00 a ticket
Step-by-step explanation:
Since you're trying to figure out how much a discounted ticket is you have to take the 15% off. So 15% of 40 is 6. Now take the 6 off of 40 (40-6) you will get 34. So the answer is $34.

Find the first five terms of the recursive sequence.
Answer:
The first five terms of the recursive sequence are;
5, 12, 19, 26, 33
Step-by-step explanation:
The given sequence is presented as follows;
aₓ = a₍ₓ ₋ ₁₎ + 7
The first term of the sequence, a₁ = 5
Therefore, we have;
a₂ = a₍₂ ₋ ₁₎ + 7 = a₁ + 7 = 5 + 7 = 12
a₃ = a₍₃ ₋ ₁₎ + 7 = a₂ + 7 = 12 + 7 = 19
a₄ = a₍₄ ₋ ₁₎ + 7 = a₃ + 7 = 19 + 7 = 26
a₅ = a₍₅ ₋ ₁₎ + 7 = a₄ + 7 = 26 + 7 = 33
The first five terms of the recursive sequence are therefore;
5, 12, 19, 26, 33.
