Answer:
180 degrees in a triangle keep that in mind it will help a lot
Step-by-step explanation:
a=180-(56+94)=30 so a=30
b=a so it is 30
c=180-(30+44)= 106
for d we go back to the small triangle with a and we know the left angle now because it it equal to c so we find the last angle of that triangle which is 44 and 180-44=d=136

Answer:
−35.713332 ; 0.313332
Step-by-step explanation:
Given that:
Sample size, n1 = 11
Sample mean, x1 = 79
Standard deviation, s1 = 18.25
Sample size, n2 = 18
Sample mean, x2 = 96.70
Standard deviation, s2 = 20.25
df = n1 + n2 - 2 ; 11 + 18 - 2 = 27
Tcritical = T0.01, 27 = 2.473
S = sqrt[(s1²/n1) + (s2²/n2)]
S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]
S = 7.284
(μ1 - μ2) = (x1 - x2) ± Tcritical * S
(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284
(μ1 - μ2) = - 17.7 ± 18.013332
-17.7 - 18.013332 ; - 17.7 + 18.013332
−35.713332 ; 0.313332
Answer:
a) 5s + 10a = 4500
s+a = 700
b) $2500
c) $1000
Step-by-step explanation:
a) Let students = s and adult = a
5s + 10a = 4500 -------1
s+a = 700 -------2
Using elimination metthod
Multiply eqn 2 by 5
5s + 10a = 4500
5s + 5a = 3500
Subtracting
5a = 1000
a =200
s = 700- 300= 500
b) if both tickets sell for $10 each
200*10 + 500*10 = $7000
Extra money that would have been made = 7000- 4500 =$2500
c) if s is $5 and a is $15
Tickets sold = 200*15 + 500*5 =$5500
Extra money made = $5500- $4500
= $1000
