Answer:
The number is even and prime.
Step-by-step explanation:
The symbol ^ represents AND, meaning that the number is true for both <em>p</em> and <em>q</em>.
Answer: the value for the associated test statistic is 1.2653
Step-by-step explanation:
Given that;
sample size one n₁ = 10
mean one x"₁ = 6.4
standard deviation one S₁ = 1.1
sample size two n₁ = 11
mean two x"₂ = 5.6
standard deviation one S₁ = 1.7
H₀ : μ₁ = μ₂
H₁ : μ₁ ≠ μ₂
Pooled Variance
sp = √( { [(n₁ - 1) × s₁² + (n₂ - 1) × s₂²] / (n₁ + n₂ - 2)} × (1/n₁ + 1/n₂))
we substitute
= √( { [(10 - 1) × (1.1)² + (11 - 1) × (1.7)²] / (10 + 11 - 2)} × (1/10 + 1/11))
= √( { [(9) × 1.21 + (10) × 2.89] / (19) } × (0.1909))
= √({[ 39.79 ] / 19} × (0.1909))
= √( 2.0942 × 0.1909)
= √( 0.39978 )
= 0.63228
Now Test Statistics will be;
t = ( x"₁ - x"₂) / sp
we substitute
t = ( 6.4 - 5.6) / 0.63228
t = 0.8 / 0.63228
t = 1.2653
Therefore the value for the associated test statistic is 1.2653
25 because -50 is negative
Answer:
20(3m-2)
Step-by-step explanation:
In order to factor, you have to look for the greatest common factor, or what the biggest number could the two numbers be divided by.
In this case, both numbers can be divided by 20, and so we put the 20 outside of the parentheses.
This leaves with 3m and -2, which are left inside the parentheses.
Hope this helps :)
Here is your answer:
Need to divide the amount he wants to the amount he gets every hour:
116.25÷7.50=15.5 hours
Which mean he has to work 15 and a half hours
Your answer is...
15.5 or if rounded 16 hours!
Hope this Helps!
