Answer:
2.0%
Step-by-step explanation:
The probability of two events happening in the sequence is calculated by multiplying the probability of each event happening separately by one another. Since there are a total of 7 letters in this word then the probability of choosing one letter correctly is [tex]\frac{1}{7}[/tex] . Since the first letter is replaced before choosing the second letter the probability remains the same. Therefore, the sequence would be the following...
[tex]\frac{1}{7} * \frac{1}{7}[/tex] = 0.020164 or 2.0%
This is an independent scenario because it does not depend on any external factors and under these circumstances the percentage will remain the same.

A recipe for chicken marinade says, ''Mix 3 parts oil with 2 parts soy sauce and 1 part orange juice. ''if you need 42 cups of marinade in all,how much of each ingredient should you see?
Answer:
Parts of oil in 42 cups of marinade = 21 cups
Parts of soy sauce in 42 cups of marinade = 14 cups
Parts of orange juice in 42 cups of marinade = 7 cups
Step-by-step explanation:
Given that:
Parts of oil = 3
Parts of soy sauce = 2
Part of orange juice = 1
Total cups of marinade = 42
To find:
How much of each ingredient should be there ?
Solution:
This problem can be solved by taking the ratio of ingredients into account.
The ratio is:
Oil : Soy Sauce : Orange Juice = 3 : 2 : 1
So, we can let the parts of oil = [tex]3x[/tex]
Parts of soy sauce = [tex]2x[/tex]
Parts of orange juice = [tex]x[/tex]
As per the question statement:
[tex]3x+2x+x=42\\\Rightarrow 6x=42\\\Rightarrow x =7[/tex]
So, parts of oil in 42 cups of marinade = 3 [tex]\times[/tex] 7 = 21 cups
Parts of soy sauce in 42 cups of marinade = 2 [tex]\times[/tex] 7 = 14 cups
Parts of orange juice in 42 cups of marinade = 7 cups

What is the simple Intrest to 1,250 at 4.5% for 2 years
Answer:
1,362.50 Dollars
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.5%/100 = 0.045 per year.
Solving our equation:
A = 1250(1 + (0.045 × 2)) = 1362.5
A = $1,362.50
Then You Get 1362.50 Dollars

Tasks: Find the price per pound of each turkey. Stater Bros.: Ralphs: Food for Less: Which store has the best price? Store name:
Answer: See explanation
Step-by-step explanation:
At Stater Bros., she found an 18 lb turkey for $21.42. The cost per pound will be:
= $21.42 / 18
= $1.19 / lb
At Ralphs, she found a 20 lb turkey for $24.20. The cost per pound will be:
= $24.20 / 20
= $1.21 / lb
At Food for Less, she found a 17 lb turkey for $18.36. The price per pound will be:
= $18.36 / 17
= $1.08 / lb
Based on the explanation, Food for Less has the best price as it's cheaper than others.

Ruben brought 2 large popcorn buckets and 4 small drins for 20. Lucia bought 2 large popcorn buckets and 2 small drinks for 14.What was the cost of the large popcorn and the small drinks
Answer:
Cost of large popcorn = 4
Cost of small drinks = 3
Step-by-step explanation:
Given that :
Let cost of large popcorn = x
Cost of small drinks = y
Cost of 2 large popcorn and 4 small drinks
2x + 4y = 20
2x + 2y = 14
x + 2y = 10 - - - (1)
x + y = 7 - - - (2)
Subtract :
2y - y = 10 - 7
y = 3
Substitute y = 3 into (2)
x + 3 = 7
x = 7 - 3
x = 4
Hence,
Cost of large popcorn = 4
Cost of small drinks = 3

Engineering=120+22x; Business=105-4x;Biology=98+6x; how many years will it be before Engineering has twice as many students as Business; how many years will it be before Engineering has twice as many students as Biology.
Answer:
Step-by-step explanation:
Given
Engineering=120+22x;
Business=105-4x;
Biology=98+6x;
If Engineering has twice as many student as biology then,;
120+22x = 2(98+6x)
Expand
120+22x = 196+12x
Collect like terms
120-196 = 12x-22x
-76 = -10x
x = -76/-10
x = 7.6
Hence it will take like 7 and a half years before engineering has twice as many student as biology

Tammy, Kelley, and Jim love reading books. Tammy read 7.75 hours last month. Kelley read 7.69 hours. Jim read 7.075 hours. Who spent the most time reading
Answer:
Tammy
Step-by-step explanation:
Tammy read 7.75 hours last month. Kelley read 7.69 hours
Jim read 7.075 hours.
We would arrange the hours of reading from smallest to the highest
7.075, 7.69, 7.75
The person who spent the most time reading is the person with the highest number of hours that was spent reading. This person is Tammy.
Therefore, person who spent the most time reading is Tammy because she read for 7.75 hours.
The person who spent the most time reading is Tammy.
Tammy read 7.75 hours last month reading.Kelley read 7.69 hours reading.Jim read for 7.075 hours.Therefore, from the decimals given, we can see that the highest is 7.75 hours that was used by Tammy.

Glen is making accessories for the soccer team. He uses 536.25 inches of fabric on headbands for 37 players and 2 coaches. He also uses 325.97 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
For Headband
Each player used 13.75 inches of fabric
For Wristband
Each player used 8.81 inches of fabric
Step-by-step explanation:
Glen is making accessories for the soccer team.
For head bands :
He uses 536.25 inches of fabric on headbands for 37 players and 2 coaches.
Let the inches of fabric used be represented by x
536.25 = 37 x + 2x
536.25 inches = 39x
x = 536.25 inches/39
x = 13.75 inches of fabric.
For Wristbands
He also uses 325.97 inches of fabric on wristbands for just the players.
Let y represent the inches of fabric used for players
We have 37 players
Hence:
325.97 = 37y
y = 325.97 inches/37
y = 8.81 inches
Therefore:
For Headbands
Each player used 13.75 inches of fabric
For Wristbands
Each player used 8.81 inches of fabric
Car Survey In a survey of 1.700 people who owned a certain type of car, 680 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car? % of the people surveyed were satisfied with the car . (Type a whole number)
Answer:
40%
Step-by-step explanation:
Total number of people who took the car survey = 1700
Number of people satisfied with a certain type of car = 680
Percent of satisfied people with the car
= [tex]\frac{\text{Total number of satisfied people with the car}}{\text{Total number of people surveyed}}\times 100[/tex]
= [tex]\frac{680}{1700}\times 100[/tex]
= 40%

Como se resuelve un circuito en serie matemáticamente?
Answer:
Step-by-step explanation:
En un circuito en serie, toda la corriente pasa a través de cada uno de los resistores, uno a la vez. Esto significa que cada resistor contribuye su resistencia completa al circuito. Si conoces el valor individual de cada resistencia, solo súmalos para encontrar la resistencia total del circuito.
In a series circuit , all of the current passes through each of the resistors, one at a time. This means that each resistor contributes its full resistance to the circuit . If you know the individual value of each resistor, just add them together to find the total resistance of the circuit .
