P(A)=0.4 and P(B)=0.6. What is the probability of observing event B three times in a row? Question 10 options:

0.240


0.360


0.064


0.216

Answers

Answer 1
Answer:

Answer:

0.216

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

The probability that an event will happen added to the probability that the event will not happen gives 1. In other words, the outcome of a probability cannot exceed 1.

The probability that an event a will happen or that another independent event  b will happen is the sum of the probability that a will happen to the probability that b will happen.

The probability that the event B will occur 3 times in a row may be interpreted as BBB and in probability, "and" is interpreted as multiplication while "or" is addition.

Pr(BBB)

= 0.6 * 0.6 * 0.6

= 0.216

the product of 8 and a number x is equal to 32. write an algebraic expression, an equation, or an inequality

Answers

The product of 8 and a number x is equal to 32 is 4.

What is product?

A product is the result of multiplication or an expression that identifies the objects (numbers or variables) to be multiplied, called factors.

The order of multiplication of real or complex numbers does not affect the product. this is called the commutative law of multiplication. When multiplying matrices or terms of several other associative algebras, the product usually depends on the order of the factors. For example, matrix multiplication is noncommutative, as is multiplication in other algebras in general.

Given:

so the  product of the two numbers (8 and x) IS equal to 32,

8x=32

x = (32)/(8)

x = 4

To learn more about product, refer;

#SPJ2
The product means multiply, so the PRODUCT of the two numbers (8 and x) IS equal to 32, so...
8x=32
(-Divide 8 on both sides to isolate the variable)
x=4
(Your result is x=4) :-)

varies directly means
if y varies directly as x that means
y=kx where k is a constant


so
y=kx
y=2 and 2/3 when y=1/4 then find k
convert 2 and 2/3 to imporoper fraction for ease
2 and 2/3=6/3+2/3=8/3

8/3=k(1/4)
multiply both sides by 4/1 to clear fraction
32/3=k

so now we have
y=(32/3)x

when x=1 and 1/8
find y
convert 1 and 1/8 to imporopor=9/8

y=(32/3)(9/8)
y=(288)/(24)
y=12

wyatt can husk at least 12 dozen ears of corn per hour and at most 18 dozen ears of corn per hour. Based on this information. what is a possible amount of time, in hours, that it could take wyatt to husk 72 dozen ears of corn?

Answers

If Wyatt can husk at least 12 an hour, then to work out how much 72 takes, we do 72 ÷ 12 to find out the time. The answer is 6.

If Wyatt can husk 18 at most, then we do 72 ÷ 18 = 4 hours.

Wyatt can husk 72 dozen ears in anywhere between 4 and 6 hours, but if you were to average it, you would get 5 hours. ((4 + 6) ÷ 2 = 5).
so a possible amount of time
find the range of highest and lowest
equation is
(number of corns per hour) times (number of hours)=72
so
12 times x=72 would be longest and
18 times y=72 would be shortest

solve
12 times x=72
divid 12
x=6
6 hours at most

18 times x=72
divide 18
x=4

at most 6 hours an at least 4 hours so
6>hours>4
any number of hours from 4 to 6 including 4 and 6

There are 250 students in a senior. of the 250 students, 102 are boys. there are 20 senior girls and 18 senior boys on the track team. What is the probablity a randomly chosen student from the senior class is a girl who does not run track?

Answers

If 102 are boys then 250 - 102 = 148 are girls.
If 20 girls run track, then 148 - 20 = 128 girls do not run track
probability a randomly chosen student from the senior class is a girl who does not run track = (probability the student chosen is a girl) * (probability the student does not run track)
= (148/250) * (128/250) = 128/250 = 62/125
