The lifetime of a certain brand of battery is normally distributed with a mean value of 8 hr and a standard deviation of 0.8 hr when it is used in a particular cassette player.Suppose that two new batteries are independently selected and put into the player. The player ceases to function as soon as one of the batteries fails.
(a) What is the probability that the player functions for at least 6 hr?
(b) What is the probability that the cassette player works for at most 9 hr?

The temperature fell by 15 degrees Fahrenheit today.
Write a signed number to represent this temperature change.
We read this out as "negative 15" or you could write "negative fifteen".
The negative indicates the temperature went down. It doesn't necessarily mean that the final temperature is -15 degrees.
For example, if it starts being 50 degrees F, and drops by 15 degrees, then 50+(-15) = 50-15 = 35 degrees is the temperature after that drop. It might help to use a vertical number line.

Given that R= 9x + 8y
Find y when x = 3 and R= 27
Answer:
1/3 or 0.3 (recurring)
Step-by-step explanation:
Let's substitute our numbers into the equation.
27 = 9x + 24 I multipled 8 by 3 in order to get 24, because x equals 3.
Now take away 24 leaving 9x on its own.
3 = 9x
Divide 9 to separate it from x.
3/9 = x
Simplify the fraction.
1/3 = x
A single card is drawn from a standard 52 card deck.
Work out the probability of choosing the "4 of spades".
Give your answer in its simplest form.
Answer:
1/52
Step-by-step explanation:
We are given that
Total number of cards=52
Number of cards of 4 of spade=1
We have to find the probability of choosing the "4 of spades".
We know that
Probability, P(E)=[tex]\frac{number\;of\;favorable\;cases}{total\;number\;of\;cases}[/tex]
Using the formula
The probability of getting 4 of spade=[tex]\frac{1}{52}[/tex]
Hence, the probability of choosing the "4 of spades"=1/52

What is 1.905 written as a mixed number in simplest form?
Answer:
1 9/10
Step-by-step explanation:
If you need this as a fraction then the answer is probably 1 9/10
The required mixed number for 1.905 is 1 905/1000 or 1 9 / 10.
Given that,
To determine the mixed fraction of 1.905.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is the fraction?Fraction is defined as the number of compositions that constitutes the Whole.
Here,
A mixed number is a number consisting of a whole number and a proper fraction.
The given number,
= 1.905
= 1 + 0.905
= 1 + 905 / 1000
= 1 905 /1000
Thus, the required mixed number for 1.905 is 1 905/1000 or 1 9 / 10.

If a+b=8, b+c=10 and c+a=12, what is the value of a+b+c?
The puzzle is solved by defining each variable in terms of another variable & a number & then making substitutions. Begin by taking each sum to define one of the variables in terms of the other. (Different combinations are available, but I’ll follow the a,b,c order.)
a+b=8 becomes a=8-b
b+c=10 becomes b=10-c
c+a=12 becomes c=12-a
Now subtract two of the equations that contain the same variable. I’ll pick two that contain an a: c+a =12 & a+b=8. Subtracting the latter from the former eliminates the “a”s, leaving c-b=4. Adding b to both sides to isolate c gives c=b+4. From above we can take b=10-c to substitute for b in c=b+4, giving us c=(10-c) + 4). Simplify the right side to c=14-c, add c to both sides, giving 2c=14, & then divide both sides by 2 to obtain c=7.
Replace the c in b=10-c with 7 to

If A = B and B = C, does A = C?
In mathematics = is assumed to be a transitive relationship. Transitivity means precisely what you stated: A = B and B = C implies A = C.
While it’s possible to use = to represent a non-transitive relationship this would be considered an abuse of notation. A ~ B or R(A, B) would be a better way to express the relation in this case.
Similar assumptions are made about operators like + and *. + is generally assumed to be commutative, whereas * can be used for noncommutative operations like matrix multiplication. E.g. A * B != B * A.
Equality in programming is another story entirely.
In many languages = is the assignment operator and == is the equality operator. Assignment is not transitive - it’s not even a relation.There are cases where the equality operator doesn’t define a transitive relation.

Hi there!
b=3·b=3b
This means:
1=3, 2=6, 3=9, 4=12, 5=15, 6=18, 7=21, 8=24, and 9=27.
Multiply by 3 everytime...
if b is 3, then the expression is is 3·b or 3b.
Final Result: 3b
As, we are given :
Minutes taken to fill Sylvia's bathtub with water = b minutes
Therefore,
Minutes taken to fill 3 bathtubs like Sylvia's bathtub = 3 × b minutes = 3b minutes
Hence, Minutes taken to fill 3 bathtubs like Sylvia's bathtub are 3b minutes.

take a look at this image, because ac=25 you set dc as x and ad as 25-x, then after that, you can form the equation root of 25^2-(x5-x)^2=root of 30^2-(x)^2 using the pythaeogrem theorem. After that you would get that x=18, then after that you just apply the theorem. 30^2-18^2 root which you would then get 24.

Answer:
29 degrees.
Step-by-step explanation:
The total of a triangle is 180 degrees.
If R = 27, that means that P and Q must make up 153 degrees.
The exterior and interior angle of Q will equal 180 degrees, as that is a straight line. Therefore, do 180 - 56 = 124, which is the degree measure of Q.
Lastly, do 153 - 124 to get 29 degrees for P.
