0.35 x 1.5 = 0.35(1 + 0.5) courtesy of the distributive property of multiplication over division.
0.35(1) + 0.35(0.5) = 0.35 + 0.175 = 0.525
You know how to arrange these in columnar form, as though you were doing it by hand?
So if there are 5 choices and only one is correct, there is a 1/5 chance of being correct. since there was 2 questions, you need to multiply 1/5 by 1/5 to get 2/25 of getting both questions correct.
i hope this helps!!
. In short is song/song = hour/hour that gives 15/2.5 = 18/h
This proportion also could be written as : 2.5/15 = h/18
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
4XZ = 144 ( divide both sides by 4 )
XZ = 36 cm
-------------------------------------------------------
Also
=
, substitute values
=
( cross- multiply )
16BC = 192 ( divide both sides by 16 )
BC = 12 cm
Answer:
14/55
Step-by-step explanation:
The word "replacement" has a total of 11 letters: 4 vowels and 7 consonants.
The probability that the first card is a vowel is 4/11.
Since the card is not replaced, the probability that the second card is a consonant is 7/10.
The probability of both is the product:
P = 4/11 × 7/10
P = 14/55
