Plus means addition and square root means √
3 plus the square root of negative 16: 3 + √-16
Minus means subtraction and square root means √
6 minus the square root of negative 64: 6 - √-64
Its asking you to multiply both quantities.
(3 + √-16) * (6 - √-64)
Best of Luck!
Answer:
V=-1
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
the formula to find slope is y1-y2/x1-x2.
The ordered pairs are (10,8) and (1,1)
(x, y). (x, y)
So it would be: 8-1 OVER 10-1
=6/9 which simplifies to 2/3
so your slope would be 2/3
Answer:
109.33
Step-by-step explanation:
given that the population has a distribution with a mean of 110 and a standard deviation of 8
Sample size n = 40
Std error of sample mean = std dev/square root of sample size
= 
From std normal distribution table we find that 30th percentile for Z is
-0.5244
Corresponding x score =
30th percentile = 109.33663
=109.33
Answer:
{x | x < - 35 / 2}
Step-by-step explanation:
-4x / 7 > 10
Multiply both sides by 7
-4x /7 * 7 > 10 * 7
-4x > 70
Divide both sides by - 4
-4x / - 4 > 70 / - 4
x < - 35 / 2 (inequality sign changes)
