5 hours on Monday, 4.5 hours on Tuesday, and 2.5 hours on Wednesday. What is the mean number of hours she worked over the three-day period?
Answer:
Mean = 4
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers there are)
There are 3 numbers
Mean = (5 + 4.5 + 2.5)/3
Mean = 12/3
Mean = 4
Answer:
[tex] \frac{5 + 4.5 + 2.5}{3 } = \frac{5 + 7}{3} = \frac{12}{3} = 4[/tex]
Please help! I need this to pass. If you are trying to get points please just chose a different question and don't mess with mine. I am in a state of trouble and I just need a helping hand.
The answer is 41
Step-by-step explanation:
To solve this we must use the formula a^2+b^2=c^2. if we substitute in the values we get 9^2+40^2=c^2. The first variable is 81, then the b variable is 1600. The hypotenuse is the c value. 81+1600 is 1681, now we must find the square root of 1681. The answer is 41. Tell me if I'm wrong :)
the point V(2,5) is rotated 180 degrees clockwise around the origin what are the coordinates of the resulting plot
Answer:
(-2,-5)
Step-by-step explanation:
When we rotate a figure of 180 degrees about the origin either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y)
Answer:
(-2 , -5)
Step-by-step explanation:
rotated 180 degrees clockwise around the origin: (x , y) -> (-x , -y)
An uber charges a flat rate of $6 plus $1.25 per mile. Kayla can spend no more than $27.50. If she wants to tip her driver $4, what is the greatest number of miles she can uber? Define the Variable for situation #1 and write an equation or inequality that represents this situation using the variable
Answer:
The cost of the uber is a $6 flat rate plus $1.25 per mile.
Then if you take an uber for x miles, the cost will be:
c(x) = $1.25*x + $6
Now, in this case Kayla also wants to add a tip of $4, then the total cost will be:
c(x) = $1.25*x + $6 + $4 = $1.25*x + $10
And we have the restriction that Kalya can't spend more than $27.50
Then the cost must be equal or smaller than $27.50, we can write this as:
c(x) ≤ $27.50
$1.25*x + $10 ≤ $27.50
Whit the above equation we can find the maximum value of x if we isolate x in one side of the inequality.
$1.25*x + $10 ≤ $27.50
$1.25*x ≤ $27.50 - $10
$1.25*x ≤ $17.50
x ≤ ($17.50/$1.50)
x ≤ 11.67
So the maximum number of miles that she can travel on that uber is 11.67 miles, but in this cases we only work with whole numbers, so we should round it to the next whole number that meets the condition, which is 11.
x = 11
The maximum number of miles that she can travel on that uber is 11 miles.
- 4/9 times - 5/8 in fractions.
Answer:
5/8 x 4/9 = 20/72 as simplified as 5/18 in fraction form. 5/8 x 4/9 = 0.2778 in decimal form.
Step-by-step explanation:
The product of -4/9 and -5/8 is 5/18.
Given are two negative fractions -4/9 and -5/8, we need to find their product,
To find the product of two negative fractions, you can multiply their numerators together and their denominators together, while keeping the negative sign.
Let's find the product of -4/9 and -5/8:
Product = (-4/9) x (-5/8)
To calculate the product, multiply the numerators and denominators:
Product = (-4 x -5) / (9 x 8)
Simplifying the multiplication:
Product = 20 / 72
Now, you can simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which in this case is 4:
Product = (20/4) / (72/4)
= 5/18
Therefore, the product of -4/9 and -5/8 is 5/18.

Linear functions have a constant rate. l, domain of all real numbers, and doesn't have a vertex.
Step-by-step explanation:
linear functions are a straight line. domain numbers can be but not limited to: -999 or 999, positive and negative numbers are included but not those with π or √ do not count because they are not real numbers. It doesn't have a vertex because it is a straight line, so therefore there is no vertex.

Answer:
9.304
Step-by-step explanation:
company wishes to estimate the mean monthly electric bill. If the standard
deviation is $400, how large a sample is required to estimate the mean electric bill to within $100
with 98% confidence?
Sample size, n = (Zcritical * σ) ÷ ME
σ = standard deviation ;
ME ≥ margin of error
α = 98% ; At 98% confidence level ;Zcritical = 2.326
n ≥ (2.326 * 400) / 100
n ≥ 930.4 / 100
n ≥ 9.304
n = 10
16. A radioactive isotope has a half-life of 13 hours. Find the amount of the isotope left from a 400-milligram
sample after 65 hours. If necessary, round your answer to the nearest thousandth.
a. 25 mg
c. 0.049 mg
b. 7.692 mg
d. 12.5 mg
Please help. I only see answers for 52 hours
Answer:
Without the math: 65 hours is 5 half-lives
13 hrs = 1/2
26 hrs = 1/4
39 hrs = 1/8
65 hrs = 1/32
(1/2)^5 = 1/32
400 mg / 32 = 12.5 mg that is, after 5 half-lives

The axis of symmetry is a vertical line passing through the vertex of the parabola with equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 3, - 6), (- 3, 4 ) with x- coordinates - 3
Then equation of axis of symmetry is x = - 3
