Answer:
11x^2+5x−19
Step-by-step explanation:
Class Frequency Mid-point
13-15 7 13+15/2=20.516-18 4 16+18/2=1719-21 3 19+21/2=2022-24 5 22+24/2=2325-27 7 25+27/2=2628-30 7 28+30/2=29
(16+18)/2 = 17
So, the answer is A (17).
Answer:
a. should not be rejected
Step-by-step explanation:
H0 : σ² = 0.003
H1 : σ² > 0.003
We obtain the test statistic :
χ² = [(n - 1) * s²] ÷ σ²
s = sample standard deviation = 0.06
n = sample size = 26
σ² = 0.003
χ² = [(26 - 1) * 0.06²] ÷ 0.003
χ² = (25 * 0.06²) / 0.003
χ² = 30
Using the Pvalue from χ² calculator :
Pvalue = 0.2242
Using α = 0.05
Pvalue > α; we fail to reject the Null
<u>Answer:</u>
The correct answer option is C. .
<u>Step-by-step explanation:</u>
We are given that two line segments AB and CD are formed from the points A (, B (, C ( and D (.
We are to determine which condition needs to be met in order to prove that AB is perpendicular to CD.
When slopes of two perpendicular lines are multiplied, they give a product of -1.
Hence option C. is the correct answer.
