Answer:
A.) 1
Step-by-step explanation:
First change the equation to 2 + ( - 8x ) = -6 so it’s easier to read
Take away 2 from both sides
So now you have -8x = -8
Divide both sides by -8 so you get positive x and 1
x = 1
95% have a systolic blood pressure between 109 and 141
Empirical rule states that for a normal distribution, 68% are within one standard deviation from the mean, 95% are within two standard deviation from the mean and 99.7% are within three standard deviation from the mean.
Given that mean (μ) = 125, standard deviation (σ) = 8.
68% are within one standard deviation = μ ± σ = 125 ± 8 = (117, 133)
95% are within two standard deviation = μ ± 2σ = 125 ± 2*8 = (109, 141)
95% have a systolic blood pressure between 109 and 141

Answer:
12
Step-by-step explanation:
Split into 2 shapes, the to find the area of the triangle you multiply base×height divided by 2.
4×3=12
12/2=6
after that find the area of the rectangle
2×3=6
add the area's together
6+6=12
Answer:
option B
Step-by-step explanation:
F(x)= 5 x-7
That notation means "translate x units to the right and y units up". If x is negative, then you move to the left, otherwise you move to the right. If y is negative, then you move down instead of up.
Translation is a geometric way of saying "shifting".
