Tyee answered 126 questions correctly on his multiple choice history final that had a total of 200 problems. What percentage of questions did Tyee answer correctly on the final exam?
Answer:
63%
Step-by-step explanation:
To convert fractions to decimals:
Divide the top of the fraction by the bottom
he got [tex]\frac{126}{200}[/tex] so
[tex]126[/tex]÷[tex]200=0.63[/tex]
To convert decimals to percentages:
multiply by 100 and add a "%" sign.
[tex]0.63[/tex]×[tex]100[/tex]=[tex]63[/tex]%
The percentage of questions Tyee answered correctly is P = 63 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage of questions Tyee answered correctly be P
Now , the total number of questions = 200
The number of questions Tyee answered correctly = 126
So , P = number of questions Tyee answered correctly / total number of questions
On simplifying , we get
P = 126 / 200
P = 0.63
Therefore , the value of P is 0.63
Hence , the percentage is 63 %

an event that has probability 1
is said to be
Answer:
guaranteed to occur
Step-by-step explanation:
An event that has a probability of 1 or in other terms P(E) = 1 is said to be guaranteed to occur. This is basically stating that the event has a 100% chance of happening, meaning that no matter what the external factors turn out to be in the scenario, the event will occur regardless. 1 basically represents 100%, while lower values such as 0.5 represent 50% when dealing with these probabilities.
A candle maker is ordering wax. Each small candle uses 12 ounces of wax. Each large candle uses 18 ounces of wax. The candle maker wants to make 42 small candles and 38 large candles.
Which answer is the most reasonable estimate of the total amount of wax needed?
700 ounces because 10 × 40 + 10 × 30 = 700
800 ouces because 10 × 20 + 20 × 30 = 800
1,200 ounces because 10 × 40 + 20 × 40 = 1,200
1,800 ounces because 10 × 20 + 40 × 40 = 1,800
Answer:
1200 Oz because 10 * 40 + 20 * 40 = 1200
Step-by-step explanation:
round 12 to 10 round 18 to 20 round 42 to 40 and 38 to 40

Answer:
ASA Congruence Theorem
Step-by-step explanation:
Already,it has been stated and proved that two angles (<ABC and <CAB) and an included side (AB) in ∆ABC are congruent to corresponding two angles (<ABD and <DAB) and an included side (AB) in ∆ABD.
Therefore, based on the ASA Congruence Theorem, ∆ABC is congruent to ∆ABD.
The missing reason is "ASA Congruence Theorem"

Sarah jumps rope to keep in shape. she jumps and average of 20 times in 15 sec. which of these describes her jump rate
60 min per jump
80 jumps per min
80 min per jump
60 jumps per min
Answer:
80 jumps per minute
Step-by-step explanation:
15 seconds is 1/4 of a minute, so to find out how many jumps she does in a minute, we multiply how many jumps she does in 15 seconds (20) by 4
20 x 4 = 80
So Sarah jumps 80 times per minute

PLease help !!!!
a is correct
Step-by-step explanation:
Area of Bigger rectangle = 4x2 + 5x - 2
Area of Smaller rectangle = x2 + 3× + 5
diff. = ( 4x2 + 5x - 2) - (x2 + 3x - 5)
= 4x2 + 5x -2-x2 - 3x - 5

HELP ASAP! I’m very confused and need help! Thanks!
Answer:
Step-by-step explanation:
Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27. So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

London and her children went into a grocery store and will buy apples and
bananas. Each apple costs $2 and each banana costs $0.80. London has a
total of $20 to spend on apples and bananas. Write an inequality that would
represent the possible values for the number of apples purchased, a, and the
number of bananas purchased, b.
Answer:
10a < 25b
Step-by-step explanation:
The required inequality, which represents the possible values for the number of apples and bananas purchased is 2a + 0.8b ≤20.
What is inequality?Inequality can be defined as the relation of the expression containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let, the number of apples purchased, a, and the number of bananas purchased, b.
According to the question, Each apple costs $2 and each banana costs $0.80. London has a total of $20 to spend on apples and bananas.
So,
2a + 0.8b ≤20
Thus, the required inequality, that represents the possible values for the number of apples and bananas purchased is 2a + 0.8b ≤20.
