Answer:

Step-by-step explanation:

To get probability of AT MOST 4 responses means all the probabilities Equal to or Less Than 4.

From the table, that is probability of 0, 1, 2, 3 or 4. (OR in probability means adding)

Hence, we add the number of editorials for P=0,1,2,3, and 4 and then divide by total number of editorials.

$P(\leq4)= \frac{20+30+56+38+34}{200}\\P(\leq4)=\frac{178}{200}\\P(\leq4)=0.89$

Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = $\frac{h}{c}$

c = $\frac{h}{\text{tan}47}$

c = $\frac{4.8}{\text{tan}47}$

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = $\frac{h}{b}$

b = $\frac{h}{\text{tan}37}$

b = $\frac{4.8}{1.0724}$

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = $\frac{h}{a}$

a = $\frac{h}{\text{tan}27}$

a = $\frac{4.8}{0.5095}$

a = 9.42 m

Which measure is of an angle that is conterminal with a 95 degree angle

timofeeve [1]

Answer: Choice B

95 - 1080n for any integer n

=================================================

Explanation:

Notice how 1080 is a multiple of 360 since 360*3 = 1080. The other values 1450, 780 and 340 are not multiples of 360. For example 1450/360 = 4.02777 approximately. We need a whole number result to show it is a multiple.

Therefore, choice B shows subtracting off a multiple of 360 from the original angle 95. In my opinion, it would be better to write 95+360n or 95-360n to make it more clear we are adding or subtracting multiples of 360.

Choice B will find coterminal angles, but there will be missing gaps. One missing coterminal angle is 95-360 = -265 degrees. So again, 95-360n is a more complete picture. I can see what your teacher is going for though.

Answer:

I believe the answer is D, but I'm not entirely sure.

Step-by-step explanation:

The Pythagorean theorem is A squared times B squared equals C squared. So your closest statement is D.
