Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve
Answer:
15 equations
Step-by-step explanation:
Let
Number of equations in the homework = x
There is only a one-word problem
y = amount of time used to solve the word problem
She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,
Total = 3x + y
52 = 3x + 7
Subtract 7 from both sides
52 - 7 = 3x + 7 - 7
45 = 3x
Divide both sides by 3
x = 45 / 3
= 15
x = 15 equations
Therefore, she solved 15 equations

probability that 450 or fewer heads come up when flipping a coin 500 times?
A. binomcdf(450, 0.5, 500)
B. binomcdf(500, 0.5, 450)
C. binomcdf(500, 450, 0.5)
D. binomcdf(450, 500, 0.5)
The expression for the situation is binomcdf(500, 0.5, 450).
The correct option is B.
What is a cumulative distribution function?The probability distribution of random variables is described using the cumulative distribution function. The probability for a discrete, continuous, or mixed variable may be described using it. The cumulative probability for a random variable is calculated by adding the probability density function.
Given:
A coin is flipped 500 times.
The probability when the coin is flipped once,
= 1/2
= 0.5
we want P (X ≤ 450), and this will use a binomial cumulative distributive function,
the parameters of a binomial cumulative distributive function are,
binomcdf (total trials, probability, up to some number)
That means,
binomcdf(500, 0.5, 450)
Therefore, binomcdf(500, 0.5, 450) is the required expression.

Answer:
y = 14
x = 10
Step-by-step explanation:
Here, we want to get the value of x and y
Since all sides are equal, then the measure of each angle is 60 degrees
Since AC = 14
y is also 14
Also;
Since each angle is 60
Then;
6x = 60
x = 60/6
x = 10

There were 239 people at Travis Scott concert.Admission to get the drive in concert was $15 for adults and $5.50 for children the total cost was 2759.50 how many adults attended and how many children attended
Answer: There are 152 adults and 87 children.
Step-by-step explanation:
Let x= Number of adults
y= Number of children
As per given, we have
x+y = 239 (i)
15x+5.50y= 2758.50 (ii)
Multiply 5.50 on both sides of (i) , we get
5.50x+5.50y=1314.5 (iii)
Subtract (iii) from (ii), we get
9.5x = 1444
⇒ x = 152
Put value of x in (i) , we get
152+y=239
⇒ y= 239-152
⇒ y= 87
Hence, there are 152 adults and 87 children.

you flip a coin twice what is the probability of getting tails then getting heads
HELP ASAP
Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.
Step-by-step explanation:
Five less than twice the value of a number is equal to three times the quantity of four more than one-half the number. What is the number?
Answer:
2x - 5 = (1/2)
4x - 10 [multiply by 2]
x - 10 = -13 [subtract 3x from both sides]
x = -3 [add 10 to both sides]
Step-by-step explanation:
The required number would be 34 which is determined by the phrase "five less than twice the value of a number is equal to three times the quantity of four more than one-half the number"
What is algebra?Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.
When broken down, these sorts of statements are not intimidating. First, consider "five less than twice the value of a number."
"Twice the value of a number" is simply 2x.
"Five less" is simply -5, so for the first part we have (2x-5)
Examine the second section next. "Three times four times more than one half the number."
"Three times the quantity" simply indicates "three times something."
4 + "one half the number" or 4 + (1/2)x is "the quantity of four more than one half the number."
So the second part is simply 3(4+x/2).
Finally, we complete the equation, (2x-5) = 3(4+x/2) and solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x = 34
Therefore, the required number would be 34.

The employer offered to pay you $20 an hour. The employer has also offered a daily commuter allowance of $20 per day to help for you transportation costs. You will be working 8 hours per day , 5 days a week. How much is it?
Answer:
$900
Step-by-step explanation:
Wages paid = $20 per hour
Transport allowance paid = $20 per day
Number of hours worked each day = 8 hours
Number of days worked each week = 5 days
To find:
Total amount paid in one week = ?
Solution:
First of all, let us find the total number of hours worked in one week.
8 hours a day and 5 number of days.
Therefore, total number of hours worked in one week = 8 [tex]\times[/tex] 5 = 40 hours
Total wages paid as per 40 hours = 40 [tex]\times[/tex] 20 = $800
Now, for these 5 days, transport allowances are paid $20 for each day.
Therefore total transport allowance = $20 [tex]\times[/tex] 5 = $100
Total wages paid = Wages as per 40 hours + Transport allowance = $800 + $100 = $900

180 = 6x + 6x + 8x
Now substituting 9 in for the x values;
180 = 6(9) + 6(9) + 8(9)
180 = 54 + 54 + 72
180 = 180
