Answer:
Step 1. The answer is no.
Step 2. The answer is b.
Step-by-step explanation:
I think Step 2 already sort of explains the reasoning behind the answer for step 1.
Hope this helps!
If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
Answer:
Y=mx+b, m= slope, b= y intercept, plug in. Y=3x+5
Step-by-step explanation:
Answer: The value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500 is $417
Profit=372.6+17.2 (advertising dollars)
Advertising dollars=$1,020
Predicted Profit=372.6+17.2 (1,020)→
Predicted Profit=372.6+17,544→
Predicted Profit=$17,916.6
Residual=Predicted Profit-Profit→
Residual=$17,916.6-$17,500→
Residual=$416.6
Rounded to the nearest integer:
Residual=$417
Answer: The value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500 is $417
Answer:
r = 2.5
Step-by-step explanation:
U= π(r+h)
Where,
U = 16 1/2
h = 2 3/4
π = 3 1/7
U= π(r+h)
16 1/2 = 3 1/7(r + 2 3/4)
33/2 = 22/7(r + 11/4)
33/2 = 22/7r + (22/7 * 11/4)
33/2 = 22/7r + 242/28
33/2 - 242/28 = 22/7r
(462-242) / 28 = 22/7r
220/28 = 22/7r
r = 220/28 ÷ 22/7
= 220/28 × 7/22
= (220 * 7) / (28 * 22)
= 1540/616
= 2.5
r = 2.5
