Angle BEC is the unmarked angle in the middle of the figure. Its value is the difference between straight angle AED (180°) and the two marked angles, 57° and 33°. That difference is ...

... 180° - 57° -33° = 90°

∠BEC is a right angle.

Answer:

Right angle

Step-by-step explanation:

We are given that

Angle AEB=57^{\circ}

Angle CED=33^{\circ}

We have to find  the classification of angle BEC

We know linear sum =180^{\circ]

Angle AEB +Angle BEC+Angle CED=180

Substitute the values then we get

57+33+\angle BEC=180^{\circ}

90+\angle BEC=180

\angle BEC=180-90

\angle BEC=90^{\circ}

Hence, the angle BEC is right angle

Suppose there are 6 runners in the finals of a 100 m sprint, Abbie, Becca, Clarice, Danna, Emma, and Francine. Answer each of th
riadik2000 [5.3K]

Step-by-step explanation:

1. Abbie's chance to place first is 12÷100 = 0.12              12÷100 = 0.12

and Becca's chance to place second is 8÷100= 0.08     8÷100= 0.08

We can determine the probability that Abbie will place first and Becca will place second because ., Abbie gets more chance than Becca                             (0.12 -0.08 =0.04) to get first place

2. Danna's chance to place first is P(A) = 48÷100 = 0.48   48÷100 = 0.48

Francine's chance to place second is P(B) = 32 ÷100 = 0.38    32 ÷100 = 0.38

The probability that Danna or Francine wins the race is

=  P(A or B) = P(A) +P(B) - P(A and B)

= 0.48 +0.32 - (0.48× 0.32)  0.48 +0.32 - (0.48× 0.32)

= 0.8 - 0.15 = 0.65       0.8 - 0.15 = 0.65

3. Yes .,that Grace's probabilities were wrong  Because Grace only informs about the winning chance of  Abbie, Becca ,Danna,and Francine.

Grace gives 12% to Abbie and 48% to Danna ., in real Abbie won the first place ., so ., Grace's probabilities were wrong

Slope = 4, point (3,-2) is on the line
Leni [432]

Answer:

y = 4x + b

Step-by-step explanation:

We know that (3, -2) is on this line. So 3 = m(-2)+b.

This leaves us with two variables the slope (m) and the y intercept (b).

But wait a minute, the slope is given to us since it says slope = 4.

Our equation is now, 3 = 4(-2)+b

3 = -8 + b

b = 11.

Our final equation is now y = 4x + b.

(y,x) is a point on this line.

Hope this helped!

How to write a slope equation using y intercept as 6 and the slope as -2
Bingel [31]
The slope equation is y=mx+b where m is the slope and b is the y intercept. After plugging the numbers into the equation you should get y=-2x+6. Hope this helps!
