Answer 1

Answer:

theoretical- what is expected to happen, 1/2

experimental- what actually happened, 1/10

Step-by-step explanation:

theoretical does not always mean that it will happen, such as flipping a coin.

it will say there is a 1/2 chance to get heads or tail.

experimental is what actually happens when you test it out. say you flip a coin 10 times and only get heads 3 times. if it was the theoretical possibility then it would say 5 heads and 5 tails.

The sum of the interior angles of a quadrilateral is 360°.

55+55+125+125=360

Answer:

D. 55, 55, 125, 125

Step-by-step explanation:

To solve this problem we first need to know what the total degrees of a 4 angle quadrilateral is. The answer to this is 360°. Knowing this, we need to figure out which combination of numbers adds up to 360. To do this, I go through the list and check all of the options.

A.) 10+10+125+125=270

B.) 15+15+25+125=180

C.) 15+15+115+125=270

D.) 55+55+125+125=360

Describe the angle relationship and solve for the x.

​

Answers

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

Part A: Explain why x = 5 makes 4x − 1 ≤ 19 true but not 4x − 1 < 19. (5 points) Part B: What value from the set {6, 7, 8, 9, 10} makes the equation 5x + 2 = 47 true? Show your work.

Answers

A) because 4 times 5 minus one equals 19 the second equation is telling me 19 is greater than 19

Answer:

M1= 35°   M2=30°

Step-by-step explanation:

At the point where the two triangle meet, the north angle is 115°, so the south one will be 115°, because they're alternate angles. This means that to get the other two angles left, you must subtract the two angles that weren't in the triangles on that point = 360° - (115 x 2) = 130°. 130° is the total of the two angles on the point in the two triangles. Then you just subtract the two angles you have for each triangle from 180° to get the last two angles

Answer: M1= 35 M2= 30
