3 0

we know that

1) Lily swims a 100-meter race

2) She swims the first half in 27.8 seconds

3) She swims the second half in 30.12 seconds

so

To find the total time to swim the whole race sum the time in the first half plus the time in second half

(27.8+30.12)=57.92\ seconds

therefore

<u>the answer is</u>

57.92\ seconds

How many positive integers less than 1000 (a) are divisible by 7? justify your answer?
mote1985 [20]
142. 

You can get this by seeing what number you have to multiply 7 by to get as close to 1000 as you can. 7*142 = 994. Thus each one of the multiplications up to that point will give you a positive integer than can be divided by 7. <span />

The height of the parallelogram is 6.4 m.

<h3>What is a parallelogram?</h3>

A parallelogram is a quadrilateral. Let us recall that a quadrilateral is a four sided figure. It is also important to recall that the opposite sides of a parallelogram are equal.

Let us now try to find the height of the parallelogram;

Given that;

/DE/ = /AC/

10 = /BC/ + /AB/

/AB/ = 10 -  /BC/

/AB/ = 10 - 6

/AB/ = 4 cm

Then;

/AE/= /CD/ = 5 cm

Using the Pythagoras theorem;

/EB/^2 = /AE/^2 + /AB/^2

/EB/ = √/AE/^2 + /AB/^2

/EB/ = √(5)^2 + (4)^2

/EB/ = √ 25 + 16

/EB/ = 6.4 m

Answer:

0.0045248 ;

0.1312218 ;

0.0001809 ;

0.1659729

Step-by-step explanation:

Number of Kings in deck = 4

Total number of cards in deck = 52

Picking without replacement :

A = King on first draw :

P(A) = 4 / 52

A = King on 2nd draw :

P(B) = 3 / 51

A = King on 3rd draw :

P(C) = 2 / 50

1.) P(A n B) = P(A) * P(B)

P(A n B) = 4/52 * 3/51 = 12 / 2652 = 0.0045248

2.) P(A u B) = P(A) + P(B) - P(AnB)

P(AuB) = 4/52 + 3/51 - 0.0045248 = 0.1312218

3.) P(A ∩ B ∩ C) = P(A) * P(B) * P(C)

P(A ∩ B ∩ C) = 4/52 * 3/51 * 2/50 = 0.0001809

4.) P(A U B U C) =

P(A) + P(B) + P(C) - P(AnB) - P(AnC) - P(BnC) - P(AnBnC)

P(AnC) = P(A) * P(C) = 4/52 * 2/50 = 0.0030769

P(BnC) = P(B) * P(C) = 3/51 * 2/50 = 0.0023529

4/52 + 3/51 + 2/50 - 0.0045248 - 0.0030769 - 0.0023529 + 0.0001809 = 0.1659729
