Trọng lượng sản phẩm do một máy sản xuất tự động là biến ngẫu nhiên X (tính theo gam) có phân phối chuẩn X ∼ N(450; 9). Sản phẩm được coi là đạt tiêu chuẩn nếu trọng lượng của nó sai lệch so với trọng lượng trung bình không quá 1 gam. Tính tỉ lệ sản phẩm đạt tiêu chuẩn. Biết Φ0(0, 11) = 0, 0438; Φ0(0, 33) = 0, 1293; Φ0(+∞) = 0, 5

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
