Answer:
C) P (X2 ≤ 8.2) = 0.96
Step-by-step explanation:
P value for the test is the probability of obtaining results that have been observed in the null hypothesis statement. A very small value of p indicates that there is unlikely chance of null hypothesis being true which means that we cannot accept null hypothesis based on the small p value.
<h2>
Answer:</h2>

<h2>
Step-by-step explanation:</h2>
For a better understanding of this problem, see the figure below. Our goal is to find
. Since:

and
is a common side both for ΔMRN and ΔMQN, then by SAS postulate, these two triangles are congruent and:

By Pythagorean theorem, for triangle NQP:

Applying Pythagorean theorem again, but for triangle MQN:

Answer:
4
a=k/b squared when a=1,b=4 k=16
When b=4 a=1
Answer:
0.2
Step-by-step explanation:
θ =
arctan( ΔY ) + 180°
ΔX
= 168.69006752598°
ΔX = -2 – 3 = -5
ΔY = 6 – 5 = 1
Distance (d) = √ΔX2 + ΔY2 = √26 = 5.0990195135928
Equation of the line:
y = -0.2x + 5.6
or
y =
- 1 x
5
+ 28
5
When x=0, y = 5.6
When y=0, x = 28
Answer:
1,584
Step-by-step explanation:
6,600 multiplied by 24%(or 0.24) is 1,584
