Answer:
Step-by-step explanation:
Connecting points O and E and points O and J, we get triangle EOJ. This triangle is equilateral triangle, because OJ=OE=JE=r=10 cm.
Since EP⊥IJ, then segment JP is the height of the triangle EOJ.
The height of the equilateral triangle can be found using formula
where a is the side length.
So,
Therefore JP is 5√3 cm
The first one is a maximum and the a.s. is x=1
The second one is a minimum and the a.s. is x=-2
Answer:
1 yard=94.44 cm
Step-by-step explanation:
-3 = x/-9
To make this easier, I'll put it in normal numbers
(-3 = x/-9) -1
3 = x/9
Multiply both sides by nine to take out the division.
27 = x
Hope that this helped!
Answer:
B
Step-by-step explanation:
Here, we are to give the reason why we would reject the null hypothesis during the hypothesis testing.
In considering whether to accept the null hypothesis or reject the null hypothesis, we have to take into consideration two things.
The p-value and the alpha value. The p-value refers to the probability which is directly obtainable from the standard score which is referred to as the z-score while the alpha refers to the level of significance.
Now, when the p-value is less than alpha, we simply reject the null hypothesis and accept the alternative hypothesis. In a case however, we have the value of p greater than or equal to the significance level alpha, we simply accept the null hypothesis in this case.
The question asks for a rejection case and this can happen only when the p-value is less than the level of significance alpha
