In The Diagram Below Chords AB And CD Intersects At E. If MAC=72 And MAEC=58. How Many Degrees Are In

Answers

Answer 1

Answer:

44°

Step-by-step explanation:

∠ DEB and ∠ AEC are vertical and congruent

Thus ∠ DEB = 58°

The measure of the chord- chord angle DEB is half the sum of the measures of the arcs intersected by the angle and its vertical angle, that is

[tex]\frac{1}{2}[/tex] (DB + AC ) = 58° ( multiply both sides by 2 )

DB + AC = 116°, that is

DB + 72° = 116° ( subtract 72° from both sides )

DB = 44°

Answer 2

Answer:

Hey, and also, The Answer to Your question is 44 Degrees.

Step-by-step explanation:

∠ DEB and ∠ AEC are vertical and congruent

Thus ∠ DEB = 58°

The measure of the chord- chord angle DEB is half the sum of the measures of the arcs intersected by the angle and its vertical angle, that is

(DB + AC ) = 58° ( multiply both sides by 2 )

DB + AC = 116°, that is

DB + 72° = 116° ( subtract 72° from both sides )

DB = 44°...... Stay safe Guys.

Using the line c = 2t - 89, how many more cups of lemonade should Lin expect to sell on Sunday than

Answers

Answer:

Lin should expect to sell 10 cups more

Step-by-step explanation:

The line c = 2t − 89 relates the cups Lin expect to sale (c) with the high temperature of the day (t)

If high temperature on Saturday is t1, then high temperature on Sunday is (t1+5)

Cups sold on Saturday are: 2t1 − 89

Cups sold on Sunday are:  2(t1+5) − 89 = 2t1 + 10 - 89

Cups sold on Sunday - Cups sold on Saturday:

2t1 + 10 - 89 - (2t1 − 89) = 2t1 + 10 - 89 - 2t1 + 89 = 10

What is the probability of picking a 7 and then picking a number greater than 7?

Write your answer as a fraction or whole number.

Answers

The probability of you picking 7 is 1/4 because there are 4 cards, and the probability of getting a card greater than 7 would be 2/3 (if you already picked 7) if not it would be 2/4, but I’m assuming it mean that you picked seven and now you’re trying to pick a higher card so i would go with 2/3

The probability of picking a 7 and then picking a number greater than 7 is 1/6.

What is probability?

Probability is the likelihood of the occurrence of an event.

Sample space = {6 or 7 or 8 or 9}

So, favorable outcomes =1( we need 7)

Total outcomes =  {6, 7, 8, 9} i.e. 4

So, the probability of picking a 7 in the first pick = 1/4

After the first pick, Sample space =  {6 or 8 or 9}

So, favorable outcomes =2( we need 8>7 or 9>7)

Total outcomes =  {6, 8, 9} i.e. 3

So, the probability of picking an 8 or 9 in the second pick = 2/3

Total probability = 1/4 * 2/3

Total probability = 1/6

Hence, the probability of picking a 7 and then picking a number greater than 7 is 1/6.

The graph below shows the hours students spent studying and their science test scores.

Hours Spent Studying vs. Science Test Scores
A graph has hours spent studying on the x-axis and test score on the y-axis. A line has a regression equation of y = 3.1 x + 40.5.

A student gets a score of 70 on the test. Based on the trend line in the scatter plot, how much time did the student spend studying?
3.1 hours
4.5 hours
9.5 hours
40.5 hours

Answers

Answer:

  (c)  9.5 hours

Step-by-step explanation:

The equation of the trend line predicts a score based on study hours. Here, we're asked for the inverse relation: finding a number of study hours based on a given score.

Inverse relation

We can solve the equation for x in terms of y:

  y = 3.1x +40.5

  y -40.5 = 3.1x . . . . subtract 40.5

  (y -40.5)/3.1 = x . . . . divide by the coefficient of x

This tells us the number of hours spent studying for a particular score.

Application

Using y=70, we find the number of study hours to be ...

  x = (70 -40.5)/3.1 = 29.5/3.1 ≈ 9.516 ≈ 9.5

The student spent about 9.5 hours studying.

If AC = 20 and BC = 17 what is the radius

Answers

The radius of the circle is 10.5.

What is the Pythagorean theorem?

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

AC = 20 and BC = 17

From the figure,

We apply the Pythagorean theorem.

So,

AC² = BC² + AB²

Substituting,

20² = 17² + AB²

AB² = 400 - 289

AB² = 111

Now,

Radius = AB

So,

AB = √111

AB = 10.535

Rounding to the nearest tenth.

AB = 10.5

Thus,

The radius of the circle is 10.5.

  10. Expanded vertically by 3, shifted left 2 and up 4.

  11. Shifted right 6 and up 7.

Step-by-step explanation:

This sort of question involves matching patterns. You need to know what the various transformations look like, and what that means for a specific parent function.

Here are the transformations used in this problem:

f(x -a)  . . . .  shift f(x) to the right by "a" unitsf(x) +a  . . . .  shift f(x) up by "a" unitsa·f(x)  . . . . .  vertically scale f(x) by a factor of "a"

For these problems, the parent function is f(x) = 1/x.

__

10. The multiplier of 3 in the numerator (3/x) means the function has been scaled vertically (expanded) by a factor of 3.

The replacement of x with x+2 means the function has been shifted to the right by -2 units. That is the same as shifted left 2 units.

The addition of 4 to the function value means the function has been shifted up by 4 units.

__

11. We note the numerator is still 1, so there is no vertical expansion. The replacement of x with x-6 means a right shift by 6 units. The addition of 7 to the function value means a shift up by 7 units.

Bailey tossed a coin 10 times. the results were 7 heads and 3 tails. What is the best comparison between the theoretical and experimental probability of tossing heads?

Answers

Answer:

The theoretical probability is greater than the experimental probability.

The best comparison between the theoretical and experimental probability of tossing heads: The theoretical probability is equal to the experimental probability.

The theoretical probability of tossing heads can be calculated as the ratio of the number of favorable outcomes (heads) to the total number of possible outcomes (heads or tails). In a fair coin, this probability is 0.5 or 50%.

The experimental probability is determined by the outcomes observed in the experiment. In this case, Bailey observed 7 heads out of 10 tosses, which gives an experimental probability of 7/10 =0.7 or 70%.

Comparing the theoretical probability (0.5 or 50%) with the experimental probability (0.7 or 70%), we find that they are not exactly the same but quite close.

Given that the experimental probability is based on a limited number of trials (10 tosses), it may not perfectly match the theoretical probability. However, with more trials, the experimental probability tends to approach the theoretical probability.

Hence, the best comparison between the theoretical and experimental probability of tossing heads is that they are approximately equal.
