Answer:
6.1-10.3
Step-by-step explanation:
Multiply standard deviation times 3 = 2.1
Subtract and add to mean.
To find f(4) ( which means ' the value of f(x) when x = 4) we replace x by 4 then simplify:-
f(4) = 4*4 + 7
= 16 + 7
= 23 (answer).
Answer:
y = (3/8)x - 1.5
Step-by-step explanation:
Use the slope-intercept form y = mx + b. Substitute -1.5 for b, 4 for x and 0 for y. Then: 0 = m(4) - 1.5, or
4m = 1.5, or
The slope is m = 1.5/4, or m = 0.375, or m = 3/8.
Note that the x-intercept can be treated just like any other point: (4, 0)
Then the desired equation is y = (3/8)x - 1.5
Answer: $27.50
Step-by-step explanation:
45% = 0.45
$50 × 0.45 = $22.50
$50 - $22.50 = $27.50
Don't worry because I be the dumb too. Me could have been using 0.55 as multiplier but am too dumb so made meself get extra step
Lol
You could have also done:
$50 × 0.55 = $27.50
Answer:
A
Step-by-step explanation:
x2 = -98
x =+-√-98
x = +-√49 • 2 • -1
x = +-7√2 • -1
x = +-7i√2
(Note: i = √-1 and i^2 = -1, so you can interchange the values)
