7.25 until 8.00 = 35 minutes
8.00 until 3.00 PM = 7 hours
3.00 until 3.15 = 15 minutes
Answer is 7 hours 50 minutes
The answer is maybe a or b
Answer:
y = 147.56 - 10.78x
Step-by-step explanation:
Given :
x = 10.2 ; y = 37.6 ; Sx = 2.8 ; Sy = 30.8 ; r = - 0.98
The regression equation :
y = mx + c
Where ;
m = slope ; c = intercept
Slope = r * (Sy/Sx)
Slope = - 0.98 * (30.8 / 2.8)
Slope = - 0.98 * 11 = - 10.78
To obtain c :
y = mx + c
y - mx = c
37.6 - (-10.78)(10.2) = c
37.6 + 109.956 = c
147.556 = c
Hence, equation becomes :
y = 147.556 - 10.78x
y = 147.56 - 10.78x
Answer:
c
Step-by-step explanation:
answer would be c
you should divide the two the two sides of the equation by 1/2b
so u get h alone in one of the sides.
Answer:
p(2) = -9
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
p(x) = -2x³ + 4x - 1
p(2) is x = 2
<u>Step 2: Solve</u>
- Substitute: p(2) = -2(2)³ + 4(2) - 1
- Evaluate: p(2) = -2(8) + 4(2) - 1
- Multiply: p(2) = -16 + 8 - 1
- Add: p(2) = -8 - 1
- Subtract: p(2) = -9
