An arithmetic sequence has a common difference.
143 - 130 = 13
156 - 143 = 13
169 - 156 = 13
The common difference is 13.
a1 = 130
a2 = 130 + 13
a3 = 130 + 2 * 13
a4 = 130 + 3 * 13
...
an = 130 + (n - 1) * 13
an = 130 + 13(n - 1)
an = 130 + 13n - 13
an = 117 + 13n
an = 13n + 117
Answer:
14.2857% decrease
≈ 14.3% decrease
Step-by-step explanation:
nearest tenths : 14.3%
nearest hundredths : 14.29%
nearest thousandths : 14.286%
I hope my answer is correct, I provided more options because I wasn't sure what nearest percent wanted.
Hope this helps!
Answer:
Y = 2x + 7
Step-by-step explanation:
We know that the slope is 2 so it is 2x
To get the y - intercept of 7 we draw the graph.
if we start at point (-1,-4) and use a slope of 2 the point that lands on the y axis is the y intercept. In this case the y intercept is 7.
Answer:
The chance of getting exactly 3 hits is = 0.20
Step-by-step explanation:
P.S - The exact question is -
As given,
F(x) = 0 , x < 1
0.30 , 1 ≤ x < 2
0.56 , 2 ≤ x < 3
0.76 , 3 ≤ x < 4
0.9 , 4 ≤ x < 5
1 , 5 ≤ x
Now,
f(x) = 0.30 , x = 1
0.56 - 0.30 = 0.26 , x = 2
0.76 - 0.56 = 0.20 , x=3
0.9 - 0.76 = 0.14 , x = 4
1 - 0.9 = 0.1 , x = 5
0, otherwise
Now,
The chance of getting exactly 3 hits is = f(x = 3) = 0.20
Answer:
Step-by-step explanation:
Here you go mate
Use PEMDAS
Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction
Step 1
3(x-4)=12 Equation/Question
Step 2
3(x-4)=12 Remove parenthesis
3x-12=12
Step 3
3x-12=12 Add 12 to sides
3x=24
Step 4
3x=24 Divide sides by 3
answer
x=8
