Find X using the given information
aleksley [76]

Answer:

Just so you hear, Whirlybot,  these circle problems are always "tricks"  and they are tough.  You have to remember a bunch of implied things

Step-by-step explanation:

One thing to recall is that the angle from the tangent point to O at the center is also a 90° angle.  so you now know, that the line from the point where the circle touches the tangent line to the center is a right angle and you have part of that 90° already.  the 50 is one part and there for the next part is 40 °  Since we now know that the line from the tangent to the center is forming an internal angle with that line going to X of 40 °  we know that X is also 40 ° b/c the triangle formed by the line to the center is going to be the same length as the line from the center to the X.  That's an Isosceles triangle.  they have the same angles at the two same length legs.  

I know, I went thur a whole pile of logic, but that's what makes this kind of problem tough.   you just have to keep thinking about things you know.

X = 40 °

5x-3y-2(4x-y) Can someone help
Lisa [10]

Answer:

-3x-1y

Step-by-step explanation:

5x - 3y⇒ -2(4x-y)

             ⇒-2(4x - y) = -8x +2y

5x - 3y -8x + 2y

<u>Combine like terms:</u>

5x- 8x= -3x

-3y +2y = -1x

<u>-3x - 1y</u>

Helppppp! please show your work!
Shtirlitz [24]

Answer:

90 - 37 will give a solid 53

Step-by-step explanation:

the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)

and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37

now we add angle degrees and sum and subtract one another,

90 - 37

The final exam scores in a statistics class were normally distributed with a mean of 70 and a standard deviation of five. What i
sp2606 [1]

The probability that a student scored less than 55% on the exam is 0.134%.

<h3>What is a normal distribution?</h3>

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have:

Mean of the sample = 70

Standard deviation = 5

= P(X<55%)

Z = (55-70)/5

Z = -3

P(X < -3)

From the Z table:

P(x<-3) = 0.0013499

or

P(x<-3) = 0.134%  

Thus, the probability that a student scored less than 55% on the exam is 0.134%.
