Answer:
x^2-6x+17.23
Step-by-step explanation:
y= -1.02(x-3)^2+9.25
multiply (x-3)(x-3)
you get -1.02+x^2-3x-3x+9+9.25
solve x^2-6x+18.25
-1.02
answer x^2-6x+17.23

Step-by-step explanation:
Answer:
510
Step-by-step explanation:
It's assumed 0 is not an integer.
M is obviously 2. The area of a square is the square of its side length. If this area must be an integer, then it must be the fourth integer, which is 4. The side length,
A prime number is a positive integer which can be divided exactly by only itself and 1. In fact, it has only those two factors. The last statement excludes 1 as a prime number. Hence, the prime numbers less than 10 are 2, 3, 5 and 7. Their sum is .
To evaluate ,
Answer:
0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 114.8 mm Hg
Standard Deviation, σ = 13.1 mm Hg
Sample size = 23
We are given that the distribution of systolic blood pressures is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
P(blood pressure is between 119 and 122 mm Hg)
0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
We know that, the sum of measures of supplementary angles is 180°
So, the Correct choice is :
because, 65° + 115° = 180°
