Answer: Andrew texted more words in 1 minute.
Step-by-step explanation:
Your question isn't well written and I could not get the exact same question online but let's reframe this:
Andrew texted 15 words in 5/12 minute. Jennifer texted 24 words in 3/4 minute. Who texted more words in 1 minute?
Since Andrew texted 15 words in 5/12 minute. The number if words texted per minute will be:
= 15 ÷ 5/12
= 15 × 12/5
= 36 words
Andrew texted 36 words per minute
Jennifer texted 24 words in 3/4 minute. The number if words texted per minute will be:
= 24 ÷ 3/4
= 24 × 4/3
= 32 words
Jennifer texted 32 words per minute.
Therefore, Andrew texted more words.
ASAP! find the inverse of the function y=2x^2+2
a.y=√x-2
b.y=√1/2x-1
c.y=√2x^2-4
d.y=√1/2x-1
Answer:
[tex]\displaystyle y=\sqrt{\frac{1}{2}x -1}[/tex]
Step-by-step explanation:
We want to find the inverse of the function:
[tex]y=2x^2+2[/tex]
To find the inverse of a function, we will flip the variables and solve for y. So:
[tex]x=2y^2+2[/tex]
Solve for y. Subtract two from both sides:
[tex]x-2=2y^2[/tex]
Divide both sides by two:
[tex]\displaystyle y^2=\frac{1}{2}x-1[/tex]
And take the principal square root of both sides. Therefore:
[tex]\displaystyle y=\sqrt{\frac{1}{2}x -1}[/tex]

The points (-6, r)
and
(6,3) lie on a line with slope 3/4. Find the missing coordinate r.
Answer:
r = -6
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
Slope 3/4
This means that [tex]m = \frac{3}{4}[/tex], and thus:
[tex]y = \frac{3}{4}x + b[/tex]
(6,3)
This means that when [tex]x = 6, y = 3[/tex]. We use this to find b. So
[tex]y = \frac{3}{4}x + b[/tex]
[tex]3 = \frac{3}{4}(6) + b[/tex]
[tex]b = 3 - \frac{18}{4} = \frac{12}{4} - \frac{18}{4} = -\frac{6}{4}[/tex]
So
[tex]y = \frac{3}{4}x - \frac{6}{4} = \frac{3x - 6}{4}[/tex]
(-6, r)
r is y when [tex]x = -6[/tex]. So
[tex]y = \frac{3(-6) - 6}{4} = -6[/tex]
So r = -6.

Solve the equation by factoring. X^2+2x-63=0
Answer:
x = -9 ; x = 7
Step-by-step explanation:
We have to find two numbers whose product is -63 and whose sum is 2
the two numbers are 9 and -7
(x+9)(x-7) = 0
x = -9
x = 7

The ratio of the numbers of students in Mr. Moore’s class compared to the number of students in Miss Henry’s class is 5:4. The ratio of the number of students in Miss Henry’s class compared to the number of students in Mr. Wilson’s class is 8:9. What is the ratio of number of students in Mr. Moore’s class to Mr. Wilson’s class.
Answer:
10:9
Step-by-step explanation:
First ratio is 5:4. 4 is equal to Henry class
If you múltiply the ratio by 2 you get
10:8, This ratio can be compared because now Henry class has 8
2(5:4)
10:8
8:9
Meaning that the answer is 10:9
6(8 - 2n) = 2n + 6
Select One:
3
0
-4
-7
Answer:
what I think it is it's -4
Answer:
n = 3
Step-by-step explanation:
6(8 - 2n) = 2n + 6
48 - 12n = 2n + 6
-12n - 2n = 6 - 48
-14n = -42
n = -42/-14
n = 3
Can someone help me please I need the mode, median, range and the mean.?
Answer:
First the mode. Since 5 popped up the most, 5 is the mode.
Next is the median. I crossed 1 dot from each side until it shows the last dot, and 5 was the last one.
After that the range. 9-2=7
Finally the worst, the mean... 2+2+3+3+3+4+5+5+5+5+5+6+6+6+8+9+9+9+9
=104/19=5.47
SO, Mode=5 Median=5 Range=7, and the mean is 5.47 (rounded nearest hundred)

If the diameter of Nicole's bike wheel is 90 cm, what is the approximate distance the wheel travels in one revolution?
Answer:
The distance traveled in one revolution is 282.6 cm.
Step-by-step explanation:
Diameter of wheel, d = 90 cm
The distance traveled by the wheel in one revolution is circumference.
The circumference of the wheel is
[tex]C = \pi\times d\\C =3.14\times 90\\C = 282.6cm[/tex]
What does it mean to have a skewed distribution? What causes
a skew in statistical terms? And how does one deal with skewed
data when conducting research? Are there specific types of
research questions and types of data where one would expect
the data to be skewed?
Answer:
Explained below.
Step-by-step explanation:
A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.
B) If in a data set, there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.
Also, if the curve is inclined to the left, it means there are few extreme values to the left and is is negatively skewed.
Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.
C) Example of a research question is;
If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data to is positively skewed.

Little’s Law Firm has just one lawyer. Customers arrive randomly at an average rate of 6 per 8 hour workday. Service times have a mean of 50 minutes and a standard deviation of 20 minutes. How long does a customer spend at Little’s Law Firm on average?
Answer:
On average, customer spends approximately 98 min at Little’s Law Firm
Step-by-step explanation:
Given the data in the question;
Arrival rate λ = 6 per 8 hours = 6 / ( 8 × 60 )min = 6 / 480 = 0.0125 per minute
Service rate δ = 1 / 50 min = 0.02 per minute
Standard deviation σ = 20 min
Now,
Utilization rate U = Arrival rate / Service rate
U = 0.0125 / 0.02
Utilization rate = 0.625
Number of people in Queue will be;
⇒ ( (λ² × σ²) + U² ) / ( 2 × ( 1 - U )
we substitute
⇒ ( (0.0125² × 20²) + 0.625² ) / ( 2 × ( 1 - 0.625 )
⇒ ( 0.0625 + 0.390625 ) / ( 2 × 0.375 )
⇒ 0.453125 / 0.75
Number of people in Queue = 0.6042
Now
Wait in the Queue = Number of people in Queue / λ
= 0.6042 / 0.0125 = 48.336
Wait Time in Office = Wait in the Queue + ( 1 / δ )
= 48.336 + ( 1 / 0.02 )
= 48.336 + 50
Wait Time in Office = 98.336 ≈ 98 min
Therefore, On average, customer spends approximately 98 min at Little’s Law Firm
