A z-score is used to measure how many standard deviations an individual value is from the mean of a given set of data.
Whose performance was better, relatively speaking?Terry Bradshaw's performance in 1979 had a z-score of 1.21, which means his performance was 1.21 standard deviations above the mean for all quarterbacks in the NFL that year.Ben Roethlisberger's performance in 2014 had a z-score of 1.31, which means his performance was 1.31 standard deviations above the mean for all quarterbacks in the NFL that year.Terry Bradshaw's performance in 1979 had a z-score of 0.98, which indicates that his performance was slightly above average. This indicates that, while his performance was impressive in 1979, it was still slightly below what other quarterbacks in the league were doing at the time. Ben Roethlisberger's performance in 2014 had a z-score of 1.51, which indicates that his performance was significantly above average. This indicates that his performance was significantly better than what other quarterbacks in the league were doing in 2014. This is a testament to the increased emphasis on the passing game in the modern NFL.To calculate the z-score for Terry Bradshaw's performance in 1979, we subtract the mean of 2789 yards from his performance of 3724 yards and divide by the standard deviation of 752 yards. This yields a z-score of 1.95. This means that his performance was 1.95 standard deviations higher than the average of other quarterbacks in the same year. Similarly, to calculate the z-score for Ben Roethlisberger's performance in 2014, we subtract the mean of 3447 yards from his performance of 4952 yards and divide by the standard deviation of 970 yards. This yields a z-score of 1.63. This means that his performance was 1.63 standard deviations higher than the average of other quarterbacks in the same year. Therefore, while both performances were impressive, Roethlisberger's performance was slightly less impressive than Bradshaw's.To learn more about numerical value refer to:

in 10 years time a father Will be twice as old as his daughter.10 years ago he was six time as old as his daughter.How old is each now
Answer:
Step-by-step explanation:
let fathers age now be x
daughters age now be y
10 years hence
(x+10)= 2(y+10)
x+10 = 2y+20
x-2y=10
10 years ago
(x-10)= 6(y-10)
x-10 = 6y-60
x-6y=-50
x-2y=10
x-6y=-50
subtract the equations
4y=60
y=15 daughter's age now
substitute y in x-2y=10
so x=40 present father's age
pls mark brainliest
Answer:
Let the age 10 years ago of daughter be ( x years ) and age of father would be ( 6x years )
After 10 years, age of father = ( 6x + 10 + 10 )
= ( 6x + 20 ) years
And Age of daughter will be = ( x + 10 + 10 )
= ( x + 20 ) years
ATQ,
6x + 20 = 2( x + 20 )
=> 6x + 20 = 2x + 40
=> 6x - 2x = 40 - 20
=> 4x = 20
=> x = 5
Hence, Present age of daughter = ( x + 10 )
= ( 5 + 10 )
= 15 years
Present age of father = ( 6x + 10 )
= 6( 5 ) + 10
= 30 + 10
= 40 years

The interest after 8 years is $240 and the balance after 8 years is $540.
What is Simple interest?Simple interest is calculated by multiplying the daily interest rate by the principal, by the number of days that elapse between payments.
Given that, You deposit $300 in a savings account. The account earns 10% simple interest per year.
SI = P*R*T/10
Where P = principal
R = rate
T = time
a) The interest earned after 8 years:-
SI = 300*10*8/100 = $240
b) The balance after 8 years:-
Amount = 300+240 = $540

The ratio of two number is 4:9.When 5 is subtracted from each of them,the new ratio becomes 3:8. Find the numbers.
Answer:
The numbers are 20 and 45
Step-by-step explanation:
Let the two numbers be a and b
The ratio of the two is 4:9
That means;
a/b = 4/9
9a = 4b •••••(i)
secondly;
Subtracting 5 from each gives a ratio of 3:8
(a-5)/(b-5) = 3/8
8(a-5) = 3(b-5)
8a - 40 = 3b - 15
3b - 15 + 40 = 8a
3b + 25 = 8a
a = (3b + 25)/8 •••(ii)
Insert this into 1
9(3b + 25)/8 = 4b
27b + 225 = 32b
32b - 27b = 225
5b = 225
b = 225/5
b = 45
From i;
9a = 4b
9a = 4 * 45
a = 4 * 45/9
a = 20

Enter an equation in the form y = mx + b that represents the function
Answer: no answer c
Step-by-step explanation:
2x-y+8z=13
3x+4y+52=18
5x-2y-72=20
Answer:
Answer is above (In the image).
Step-by-step explanation:
I am not sure if that is what you were looking for. To convert it to decimals, just input the figures into your calculator.
In my opinion the best way to solve these equations are elimination, therefore I will be giving my answer in this way!
2x-y+8z=13 1️⃣
3x+4y+52=182️⃣
5x-2y-72=203️⃣
We first combine liked terms in equation 2 and 3.
2️⃣turns into 3x+4y=-34 let's call it 2️⃣'
3️⃣turns into 5x-2y=92 let's call it 3️⃣'
Then solve for x
3️⃣'*2
10x-4y=184
3️⃣+2️⃣
13x=150
x=150/13
Now substitute the x back into equation 2️⃣'
3*150/13+4y=-34
450/13+4y=-442/13
4y=-892/13
2y=-446/13
y=-223/13
Now we can substitute this back into 1️⃣ to solve for z
2*150/13- - 223/13+8z=169/13
523/13+8z=169/13
8z=-354/13
4z=-177/13
z=-177/52
This problem is kind of messy so let me restate my answer!
x=150/13
y=-223/13
z=-177/52
I really hoped this is correct and it helped, and would appreciate it if you give me brainlliest! If you have any more questions about my solution please ask me in the comments!
