Answer:
A.) x=90°
Step-by-step explanation:
Note:
The triangle shown is an isosceles triangle, which means that it has 2 congruent sides (as shown by the small intersecting lines), and this also means that it has two congruent angles.
We are given an angle measure adjacent to one of the missing angles. These two form supplementary angles, which means that they're sum is equal to 180°, or a straight line. So, to find:
y is the unknown angle. Solve for y:
y is 45°. Since this and the other angle are congruent, add:
Note:
Triangles angles will always add up to a total of 180°.
To find the missing angle x°, use:
These are the angles in a triangle. Substitute any known values and solve:
The missing angle x° is 90°.

Answer:
m(x) = (8 oz/day)x oz
Step-by-step explanation:
Since x measures time, in days, start your x-axis at (0,0).
The rate at which you drink milk is 8 oz/ day.
If x represents the number of days you drink milk (same amount daily), the desired equation is
m(x) = (8 oz/day)x oz
Answer:
0.0139
Step-by-step explanation:
Given that in a test for extrasensory perception, the experimenter looks at cards containing either a star, circle, wave, or square. (The subject cannot see the cards.)
Probability for guessing a correct shape out of 4 shapes = 0.25
Each trial is independent of the other
Hence X no of correct guesses is binomial with n = number of cards = 20 and p = constant probability =0.25
the probability a subject correctly guesses at least 10 of the 20 shapes
=
, where F represents the cumulative probability upto 9
= 0.0139
Answer:
You'd think its 34% but apparently it's 16%.
I hope this is right. If its not then it must be 34%.
(A) -- or maybe (B). 80% confident it is A.

Answer: 4 tiles
Explanation: if the square has a width of one foot then the length is also one foot since all sides are equal. Therefore 4 squares can fit along a 4 foot wall
