Hello! I can help!
10:
a. 4-5 magazines interval contains the fewest data values.
b. There are 20 students in the class. 15 + 3 + 2 is 20.
c. Ignore the 6-7 interval and count the students from the others. 17/20 students read less than 6 magazines. 85% of students read less than 6 magazines.
d. You can’t exactly find the mean of the data, because you don’t know the exact number of how many each student read. The median would be in the range of 2-3, but you can’t find that either. You can’t find any of them without the exact numbers.
11. There were way more than 12% of songs that took 5-8 seconds to download. The error was getting the number of songs that took that long to download and putting it as a percentage. 12/36 songs took 5-8 seconds to download. 12/36 equals 1/3 (0.333) or simply 33%. The real answer is that 33% of the songs took 5-8 seconds to download.
Hi there! :)
Answer:
y = -2x + 3
Step-by-step explanation:
We can write an equation in slope-intercept form. Use the slope formula to find the rate of change in the table:
Plug in values from the table:
Simplify:
m = -2 (rate of change)
Use a point from the table (-2, 7) and the slope to solve for the equation for the linear function:
7 = -2(-2) + b
7 = 4 + b
7 -4 = b
b = 3
Rewrite:
y = -2x + 3 is the equation for the linear function.
Answer:
Step-by-step explanation:
I think the missing equation in your question is: h(t) = -16 
+ 16t + 480
Here is my answer:
As we know that the vertex form of a parabola, y=a
+ k where(h,k) is the vertex
h(t) = -16 + 16t + 480
= -16 (
+ 480
= -16 
+ 484
So the vertex is (
, 484)
a. It take for Joseph second to reach his maximum height
b. The highest point that Joseph reached is the vertex of the function, it is 484 ft
c. Joseph hit the water after how many seconds?
<=> h(t) = 0
<=> -16 + 16t + 480 = 0
<=> t = 
second = 6 sec
Hope it will find you well
Yes because they have two sides that are parallel
Answer:
Step-by-step explanation:
y= a*b x (a is initial value b= growth rate)
y=8000(-1)^1 x= 1.018^ 1* 1.8
x=0.1527= time* 12
f(x)=x. f ( x )= x. = 0.1527 * 12
or we can square so that x^2=1.8 and x= 1.34164 note this can only be used for the first 5 decimal place.
This shows the exponential growth we expand and introduce y=8000 (-1)^12 to find one year.
one year y-1^ 12 this represents 144 the 1.8% of the y=144 the starting point of 1/12 on axis
f(x)=2x. f (x )= 2x add y (1)^1 would sh9ow year 2 at athe same rate
