Answer:

x = 6

Step-by-step explanation:

<u>GIVEN :-</u>

  • AD ║ BC
  • AE = 16 units
  • AB = 5x + 2 units
  • DE = 12 units
  • DC = 24 units

<u>TO FIND :-</u>

  • Value of x

<u>GENERAL CONCEPT TO BE USED IN THIS QUESTION :-</u>

<em>Basic Proportionality Theorem -</em>

If a line drawn parallel to one side of a triangle and intersects the other two sides at distinct points , it divides the other two sides in equal proportion.

<u>SOLUTION :-</u>

AD is the line drawn parallel to BC and intersects EB & EC at A & D respectively. By using Basic Proportionality Theorem , it can be stated that -

\frac{AE}{AB} = \frac{DE}{DC}

=> \frac{16}{5x + 2} = \frac{12}{24}

=> \frac{16}{5x + 2} = \frac{1}{2}

=> 5x + 2 = 16 \times 2 = 32

=> 5x = 32 - 2 = 30

=> x = \frac{30}{5} = 6

John and Abel each had a cup of ice cream. John ate 1/4 of the cup of ice-cream and Abel left just 1/4 cup of ice-cream from his
PSYCHO15rus [73]

Abel ate 1/4 more than John.

If it started with 4/4 then John ate 1/4 and Abel ate 2/4 so 1/4 would be left.

Hope this helps

Need help please with this question. Thank you:)
adell [148]

Answer:

\hat y = 2*10 -4= 16

And the real value for this case is y=14. The residual is defined as:

e= y -\hat y

Replacing we got:

e = 14 -16 = -2

And the best answer would be:

-2

Step-by-step explanation:

For this case we know that the best fit line for the relationship between x and y is given by:

\hat y = 2x-4

And we know that an  individual in the dataset has a score of 10 on the x-variable and a score of  14 on the y-variable. So then we can find the estimated value like this:

\hat y = 2*10 -4= 16

And the real value for this case is y=14. The residual is defined as:

e= y -\hat y

Replacing we got:

e = 14 -16 = -2

And the best answer would be:

-2
