I did 2-
d) Square root of 16 plus 3 to the second power (exponent)
3 to the 2nd power = 9
square root of 16 is 4 so 9+4=13
g) Square root of 25 to the power of 2 + (2+3)
2+3= 5 then square root of 25 = 5 to the second power is 25 = 30
Answer:
Step-by-step explanation:
To Test :-
H0 :- P = 0.12
H1 :- P ≠ 0.12
P = X / n = 156/800 = 0.195
Test Statistic :-
Z = ( P - P0 ) / ( √((P0 * q0)/n)
Z = ( 0.195 - 0.12 ) / ( √(( 0.12 * 0.88) /800))
Z = 6.5279
Test Criteria :-
Reject null hypothesis if Z > Z(α/2)
Z(α/2) = Z(0.05/2) = 1.96
Z > Z(α/2) = 6.5279 > 1.96, hence we reject the null hypothesis
Conclusion :- We Reject H0
There is sufficient evidence to support the claim that there is a difference.
Proportional:
82.8 / 92 = 0.9
73.8 / 82 = 0.9
so
FG / 47 = 0.9
FG = 47 * 0.9
FG = 42.3
answer
The distance between 2 campsites is 42.3 m.
Answer:
15.68$
Step-by-step explanation:
You calculate the price of one lollipop:
4.48/2= 2.24
The multiply that by 7.
2.24*7= 15.68$
So the sum of 4 times a number (4 times x or 4x) and 7 (+7) is (=) 19 (19)
4x+7=19
subtract 7 from both sdies
4x=12
divide by 4
x=3
the number is 3
