Your answer is A because You have the equation P=3275+125t The populations of the town is 5,900 so then add that into the equation which would be 5900=3275 + 125t Solvay and your answer is 21 which would be the year 1921 which your is A
Her hand is 7 inches and her foot is 11, 11-7=4.
4 inches ⭐️
Speed = Distance/Time
Runner Speed = 200/21.3 = 9.4 m/s
Swimmer Speed = 1.8 m/s
9.4 - 1.8 = 7.6 m/s
C
Answer:
a) T test
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
Step-by-step explanation:
Construction of hypothesis
H₀ : p = 75
H₁ : p ≠ 75
Here Standard deviation = 7
sample = n = 50
Average = x-bar = 78
Level of significance:
∝ = 5% = 0.05
Degree of freedom:
df = n-1
= 50 -1 = 49
Critical value :
± 1.96
a) T test
test t is used as average X mean is used
Test Statistic:
t = X₂ - X₁ / Sd /√n
= 78 - 75 / 7/√50
=3.0304
Critical region :
We take two tail T test
test statistic is in reject interval. Reject H₀
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
Step-by-step explanation:
- 3x-12>-6
- 3x-12+12>-6+12
- 3x>6
- x<6/3
- x<2
