Answer:

Answer:

  2. ASA can be used with the definition of an isosceles triangle

  3. x = 5 5/6

Step-by-step explanation:

2.

Using the given information, the definition of an isosceles triangle tells us, ...

  ∠A = ∠C and ∠A = ∠ABM and ∠C = ∠CBN

By substitution, ∠ABM = ∠CBN. This lets us declare ΔAMB ≅ ΔCNB by ASA, where the sides between the angles are AB and CB.

__

3.

If the angles of interest are the same, then the triangles are similar. That means corresponding sides have the same ratio:

  AB/AD = CB/CE

  x/7 = (10-x)/5

  5x = 7(10 -x) = 70 -7x . . . . . multiply by 35, simplify

  12x = 70 . . . . . . . . . . . add 7x

  x = 70/12 = 35/6

  x = 5 5/6

Which two numbers on the number line have an absolute value of 1.75?Select the location of both numbers on the number line.

Answers

Answer:

The absolute value of a number is the distance of the number from zero on the line. The line has always values increasing from left to right. Right side is greater than the left side.

Every absolute value has two numbers on the line like absolute value of 1 has two points, one is 1 and the other is -1. Hence the absolute value of 1.75 also has two numbers on the line one is 1.75 and other is -1.75.

So the point 1.75 can be found on the right side of zero at a distance of 1.75 and in the middle of point 1.5 and 2. Again -1.75 point can be found at the left side of zero at a distance of 1.75 and in the middle of -1.5 and -2.

Note: Refer the image attached. The Red colour marks in the image attached shows the location of both numbers on the number line.

Answer:

-1.75 and 1.75

Step-by-step explanation:

The absolute value is the distance that certain number has from it's position to the number 0.

There are only two numbers that have a distance of 1.75 to the number 0: -1.75 and 1.75.

The location on the graph must be marked on the line that is between -1.5 and -2, and between 1.5 and 2.

If the probability that a bird will lay an egg is 75%, the probability that the egg will hatch is 50%, and the probability that the chick will be eaten by a snake before it fledges is 20%, what is the probability that a parent will have progeny that survive to adulthood?(A) 30%
(B) 14.5%
(C) 7.5%
(D) 2%

Answers

Answer: (A) 30%

Step-by-step explanation:

Given : The probability that a bird will lay an egg =0.75

The probability that the egg will hatch  =0.50

Now, the probability that the egg will lay an egg and hatch = 0.75*0.50

Also,The probability that the chick will be eaten by a snake before it fledges =0.20

Then, the probability that the chick will not  be eaten by a snake before it fledges : 1-0.20=0.80

Now, the probability that a parent will have progeny that survive to adulthood will be :-

0.75*0.50*0.80=0.30=30\%

Hence, the probability that a parent will have progeny that survive to adulthood =  30%

A number is selected atrandom from each of the sets
£2,3,4} and {1, 3, 5}. Find the
Probability that the sum of the two numbers is greater than 3 but less than 7?
​

Answers

Answer:

0.4444 = 44.44% probability that the sum of the two numbers is greater than 3 but less than 7.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

A number is selected at random from each of the sets {2,3,4} and {1, 3, 5}.

The possible values for the sum are:

2 + 1 = 3

2 + 3 = 5

2 + 5 = 7

3 + 1 = 4

3 + 3 = 6

3 + 5 = 8

4 + 1 = 5

4 + 3 = 7

4 + 5 = 9

Find the probability that the sum of the two numbers is greater than 3 but less than 7?

​4 of the 9 sums are greater than 3 but less than 7. So

p = (4)/(9) = 0.4444

0.4444 = 44.44% probability that the sum of the two numbers is greater than 3 but less than 7.
