Answer:
The equation are:
1) h + s = 20
2) 4h = 1s
Step-by-step explanation:
Number of hats Elliott made = h
Number of scarfs Elliott made = s
total number of items Elliott made = 20
h + s = 20 ..[1]
1 hat uses 0.2 kilograms of yarn
1 hat = 0.2 kg of yarn
Then h hats will use = 0.2h kg of yarn
1 scarf uses 0.1 kilograms of yarn
1 scarf= 0.1 kg of yarn
Then s scarfs will use = 0.1s kg of yarn
She wants to twice as much as yarn for scarves for hats:
2 × (0.2h kg of yarn) = 0.1s kg of yarn
0.4h = 0.1s
4h = 1s...[2]
The equation are:
1) h + s = 20
2) 4h = 1s

Answer:
4x +14 . . . feet
Step-by-step explanation:
The perimeter is given by ...
P = 2(L+W)
P = 2((x +4) +(x +3)) = 2(2x +7)
P = 4x +14
The perimeter of the garden is 4x +14 feet.
Answer:
The 95% confidence interval is (29.54 - 53.46}
Step-by-step explanation:
given data:

Se = 6.1
n = 755
a) best estimate 
b) at 95% confidence interval



at 95% confidence interval for [/tex]\mu[/tex]



The 95% confidence interval is (29.54 - 53.46}
A=p(1+i/m)^mn
A=3,500×(1+0.0229÷12)^(12×6)
A=4,014.98
