Expanded form is just each place value split into addition.
so 1,852 is
1000 + 800 + 50 + 2
that's all
Answer:
slope of line ax + by = c is -a/b
so, slope of 7x +2y =5 is -7/2
Answer:
300+ 12h=450
12h=150
h=12.5
Step-by-step explanation:
Properly formula based step solved
Answer:
Test statistic = - 0.851063
- 2.520463
Step-by-step explanation:
H0 : μ ≥ 15
H1 : μ < 15
Sample mean, xbar = 14.5
Sample standard deviation, s = 4.7
Sample size = 64
Teat statistic :
(xbar - μ) ÷ (s/√(n))
(14.5 - 15) ÷ (4.7/√(64))
= - 0.851063
The critical value at α = 0.05
Using the T - distribution :
Degree of freedom, df = 64 - 1 = 63
Tcritical(0.05, 63) = 1.6694
Test statistic - critical value
-0.851063 - 1.6694
= - 2.520463
