First find what x is equal to
x - 3 = 10
add 3
x = 13
Plug 13 for x
8 * 13 + 7 = 111
Answer: 0.790
Step-by-step explanation:
Given : The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.
The sample size : n= 2004
The number of students read above the eighth grade level = 1584
Then , the proportion of students read above the eighth grade level is given by :-
Hence, the estimate proportion of tenth graders reading at or below the eighth grade level =0.790
Answer:
ans: 37/ 32
Step-by-step explanation:
(33/8 + 1/2 ) / ( 4/5 ×2)
= { ( 33 + 4) / 8} / ( 8 / 2)
= 37/ (4×8)
= 37 / 32
Answer:
120
Step-by-step explanation:
First, you have to calculate the money that Seth would spent if he goes to 30 movies if his father gets the summer movie pass by adding up the cost of the pass plus the result of multiplying the cost per movie with the pass for the number of movies:
30+(3*30)=30+90=120
Second, you need to calculate the money that Seth would spent if he goes to 30 movies without the pass by multiplying the normal price per movie for the number of movies:
8*30=240
Third, you need to find the difference between both costs:
240-120=120
According to this, the answer is that if Seth plans to go to 30 movies this summer, he would save 120.
Answer:
Giả sử hàm số y = f(x) có đạo hàm f'(x)
Đạo hàm của hàm số f'(x), nếu có, được gọi là đạo hàm cấp hai của hàm số f(x), kí hiệu là y'' hay f''(x).
Đạo hàm của hàm số f''(x), nếu có, được gọi là đạo hàm cấp ba của hàm số f(x), kí hiệu là y''' hay f'''(x).
Tương tự, đạo hàm của đạo hàm cấp (n-1) được gọi là đạo hàm cấp n của hàm số y = f(x), kí hiệu là y(n) hay f(n)(x).
