A line passes through the points (1, -6) and (4,3). - 1

Answers

Answer 1
Answer: After plugging in the points into the formula y2-y1/x2-x1, you’ll find that the slope is 3 or 3/1. Slope is written as rise over run. Using this information, you’ll see that the y-intercept is (0,-9). Hopefully I’m right and hopefully this helps!

Answer: -9

Answers

1 and 1/3 of them are.
well 1 ÷ 3/4 = 0.08 so only 1 and 1/3 because if there is 2 you would have 6/4 which equals 1 1/2 which isn't one

A scale model of a building is 2.3 feet high. The ratio of the height of the model to the height of the building is 11:56. How tall is the building, in feet?

Answers

2.3 ------------ 11
x    ------------ 56
then x= (2.3x56)/11

also easier would be just to multiply by 56/11.

Divide 7/24 by 35/48 and reduce the quotient to the lowest fraction. A. 245/1152

C. 4/10
D. 42/48

Answers

well first you have to flip one of the fractions, so for example 7/24 x 48/35 which should give you an answer of 336/840. If you simplify this down you should get 4/10. Another way of double-checking or simplifying is by dividing 336 by 840 (which should give you 0.4) and dividing 4 by 10 (which should also give you 0.4). Hope this helps!

Determine whether the following probability experiment represents a binomial experiment and explain the reason for your answer. Three cards are selected from a standard​ 52-card deck without replacement. The number of acesaces selected is recorded. Does the probability experiment represent a binomial​ experiment?

Answers

Answer:

No. See explanation below.

Step-by-step explanation:

Since the cards are being selected without replacement, every time we select a card, the probability varies (since there is one less card) and therefore, the probability doesn't remain the same for every trial and therefore, the probability of success changes for every trial.

It is because of this that this probability experiment doesn't represent a binomial experiment.

If any two sides and any angle are congruent in two triangles, then the triangles must be congruent. is it true or false?

Answers

Answer:

FALSE

Step-by-step explanation:

To Find: True or False

If any two sides and any angle are congruent in two triangles, then the triangles must be congruent.

It is not always true according to rule of congruence. If two sides are equal then angle between them must be equal for SAS property.

It is false

Total possible congruence for two sides and one angle :  SSA , A-SS,    SAS  

Only three possible property.

SAS is only true for concurrency of triangle.

SSA and A-SS are false for any two side and any one angle.

Please find the attachment for difference in three property.

Hence, The given statement is false.

Well,  It is False. The sides must form the angle, i.e. /_ <- the angle formed, and the two sides must be in this position. its the ASA postulate.


I hope this helps!
