Answer:
48.9%, and 489/1000
Step-by-step explanation:
It is currently written as a decimal. To convert to a percent, simply move the decimal place over to the right by 2 places. For the fraction, calculate the place value of the last digit, which in this case, is the thousandths. So, the fraction would be 489/1000

What is the 9th term in a geometric sequence with a common ratio of 2 and a first term of 3
Answer: 768
Step-by-step explanation:
Just multiply 2 by the first term (3) until u get to the 9th term
So 1.. 3*2= 6
2.. 6*2=12
3.. 12*2= 24
& so forth
So the 9th term is 768
8x + 5y = 35 solve for y
Answer:
y = -8/5x + 7
Step-by-step explanation:
Step 1: Write equation
8x + 5y = 35
Step 2: Solve for y
Subtract 8x on both sides: 5y = 35 - 8xDivide both sides by 5: y = 7 - 8/5xRewrite: y = -8/5x + 7Maddie loves bananas! So, Maddie bought 15 boxes of bananas. In each box of bananas, there are 32 bananas. How many total bananas did Maddie buy?

A football coach needs to divide 48 players into two groups. He wants the ratio of the players in group 1 to players in group 2 to be 3. How many players in group 2?
Answer:
45
Step-by-step explanation:
A ratio shows us the number of times a number contains another number. The number of players in group 2 is 12.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the coach wants the ratio of the players in group 1 to players in group 2 to be 3. Therefore, the ratio can be written as,
Number of players in group1/Number of players in group2 = 3/1
Multiply the numerator and the denominator of the ratio by x,
Number of players in group1/Number of players in group2 = 3x /1x
Now, the total number of players can be written as,
3x + x = 48
4x = 48
x = 48/4
x = 12
Further, the number of players in group 2 can be written as,
Number of players in group2 = x = 12
Hence, the number of players in group 2 is 12.

Step-by-step explanation:
According to the Alternating Series Estimation Theorem:
│aₙ₊₁│≤ ε
1 / (4 (n + 1)⁴) ≤ 0.00005
4 (n + 1)⁴ ≥ 20000

Three times a number, increased by one, is between negative eleven and seven. Find all the numbers
Answer:
7 < 3N+1 < 11
6 < 3n < 10
2 < n < 10/3
Step-by-step explanation:
The required number is -3, -2, -1, 0, and 1 which is three times a number, increased by one, is between negative eleven and seven.
Given that,
Three times a number, increased by one, is between negative eleven and seven. the number is to be determined.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
here,
Accoding to the condition let the number be x,
and
-11 < 3x + 1 < 7
-12 < 3x < 6
-4 < x < 2
So the number are -3, -2, -1, 0, anb 1
Thus, the required number is -3, -2, -1, 0, and 1 which is three times a number, increased by one, is between negative eleven and seven.

The solution to the radical expression √36 is 6.
What is a radical expression?A radical expression is a mathematical expression that contains a radical symbol (√), which represents the square root (or nth root) of a number or variable. The radical symbol is typically followed by a number or expression inside a set of parentheses, which indicates what is being rooted.
The square root of 36 is a number that, when multiplied by itself, equals 36. In this case, we know that the number is 6, because 6 x 6 = 36.
The square root of 36 is simply:

1.) A pipe bursts in your house and you call 2 plumbers for estimates. Plumber A says he
charges $40 to check the problem and $ 55 an hour to repair. Plumber B says he
charges $ 60 to check the problem and $ 40 an hour. If the repair takes 4 hours to
complete, which plumber would be a better option.
Answer: Plumber B
Step-by-step explanation:
Plumber A: First, multiply $55 times 4, then add the fee of $40. This will give you $260 as total. This is how much it would cost for Plumber A.
Plumber B: Multiply $40 by 4 and then add $60. This gives you $220, showing that Plumber B is a better option.
Answer:
Plumber B
Step-by-step explanation:
We could set up 2 expressions, and set the time to be 4 hours, and see which plumber costs less:
Plumber A: 40+55*4 = $260
Plumber B: 60+40*4 = $220
Plumber B is cheaper, so therefore he/she is the better option.

Baby weights: The weight of male babies less than 2 months old in the United States is normally distributed with mean 11.8 pounds and standard deviation 3.1 pounds. Use the TI-84 Plus calculator to answer the following. (a) What proportion of babies weigh more than 13 pounds? (b) What proportion of babies weigh less than 14 pounds? (c) What proportion of babies weigh between 11 and 15.8 pounds? (d) Is it unusual for a baby to weigh more than 18 pounds? Round the answers to four decimal places.
Answer:
(a)0.3493
(b) 0.7611
(c) 0.5034
(d) No it is not unusual
Step-by-step explanation:
Using the TI-84 Plus calculator to answer the following
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean 11.8 pounds and Standard deviation 3.1 pounds.
(a) What proportion of babies weigh more than 13 pounds?
z = (x-μ)/σ
= 13 - 11.8/3.1
= 0.3871
Probability value from Z-Table:
P(x<13) = 0.65066
P(x>13) = 1 - P(x<13) = 0.34934
The proportion of babies weigh more than 13 pounds is 0.3493
(b) What proportion of babies weigh less than 14 pounds?
z = (x-μ)/σ
= 14 - 11.8/3.1
= 0.70968
Probability value from Z-Table:
P(x<14) = 0.76105
The proportion of babies weigh less than 14 pounds is 0.7611
(c) What proportion of babies weigh between 11 and 15.8 pounds?
For x = 11
z = (x-μ)/σ
= 11 - 11.8/3.1
= -0.25806
Probability value from Z-Table:
P(x = 11) = 0.39818
For x = 15.8
z = (x-μ)/σ
= 15.8 - 11.8/3.1
= 1.29032
Probability value from Z-Table:
P(x = 15.8) = 0.90153
The proportion of babies weigh between 11 and 15.8 pounds
P(x = 15.8) - P(x = 11)
= 0.90153 - 0.39818
= 0.50335
≈ 4 decimal places = 0.5034
(d) Is it unusual for a baby to weigh more than 18 pounds?
z = (x-μ)/σ
= 18 - 11.8/3.1
= 2
Probability value from Z-Table:
P(x≤ 18) = P(x = 18) =
0.97725
No it is not unusual to have a Weight of 18 pounds
Round the answers to four decimal places.
(a) The proportion of babies weigh more than 13 pounds is 0.3493.
(b) The proportion of babies weigh less than 14 pounds is 0.7611.
(c) The proportion of babies weigh between 11 and 15.8 pounds is 0.5034.
(d) No, it is not unusual.
"To understand the calculation, check below."
ProbabilityFormula:
z = (x-μ)/σ,
x is the raw score.
μ is the population mean.
σ is the population standard deviation.
Mean = 11.8 pounds
Standard deviation =3.1 pounds.
Part (a) :
The proportion of babies weigh more than 13 pounds is :
z = (x-μ)/σ
z = 13 - 11.8/3.1
z = 0.3871
Probability value from Z-Table:
P(x<13) = 0.65066
P(x>13) = 1 - P(x<13) = 0.34934
The proportion of babies weigh more than 13 pounds is 0.3493
Part (b):
The proportion of babies weigh less than 14 pounds is :
z = (x-μ)/σ
z= 14 - 11.8/3.1
z= 0.70968
Probability value from Z-Table:
P(x<14) = 0.76105
The proportion of babies weigh less than 14 pounds is 0.7611.
Part (c):
The proportion of babies weigh between 11 and 15.8 pounds is :
For x = 11
z = (x-μ)/σ
z= 11 - 11.8/3.1
z= -0.25806
Probability value from Z-Table:
P(x = 11) = 0.39818
For x = 15.8
z = (x-μ)/σ
z= 15.8 - 11.8/3.1
z= 1.29032
Probability value from Z-Table:
P(x = 15.8) = 0.90153
The proportion of babies weigh between 11 and 15.8 pounds:
P(x = 15.8) - P(x = 11)
= 0.90153 - 0.39818
= 0.50335
≈ 4 decimal places = 0.5034
Part (d) :
Is it unusual for a baby to weigh more than 18 pounds :
z = (x-μ)/σ
z = 18 - 11.8/3.1
z = 2
Probability value from Z-Table:
P(x≤ 18) = P(x = 18) =0.97725
No, it is not unusual to have a Weight of 18 pounds.
