Answer:
4.5
Step-by-step explanation:
Answer:
28
Step-by-step explanation:
The ratio of the triangles is 12:15 which is equal to 4:5
Then you can use that ratio to find the ?
35 would be the 5 so 4 would be multiplyed by 7
Which is equal to 28
In the question, the given expression is

And we have to find the equivalent expression to the given expression .
First we remove the parenthesis

Now we combine the like terms, and here like terms are z and z, therefore on combining , we will get

And that's the required equivalent expression .
A conditional statement is any statement in the "If..., then..." form. The converse switches the hypothesis and the conclusion. It's easiest to demonstrate this in an example:
Our statement will be "If an animal is a dog, then it has four legs." Now to switch the hypothesis and conclusion, we take the "an animal is a dog" part, and switch it with the "it has four legs" part". I will change the wording slightly so the sentence still makes grammatical sense: "If an animal has four legs, then it is a dog".
Now the final statement from the previous example serves as the perfect false conditional statement with a true converse:
Statement: "If an animal has four legs, then it is a dog", clearly false.
Converse: "If an animal is a dog, then it has four legs", a true statement.
Answer:
a) 0.145
b) 0.013
c) 0.783
d) 0.586
Step-by-step explanation:
a) there are always 52 cards in total, 13 hearts
Pa = 39/52 × 38/51 × 13/50 = 19266/132600 = 257/1700 =0.145
b) there are always 13 diamonds in a complete card
Pb = 13/52 × 12/51× 11/50 = 11/850 = 0.013
c) there are always 4 aces, and 48 that are not aces
Pc = 48/52 × 47/51 × 46/50 = 4324/5525 = 0.783
d) there are 13 hearts,to get at least one heart we have.
Pd = 1 - p
Where p is the probability of no hearts
p = 39/52 × 38/51 × 37/50 = 703/1700 = 0.414
Pd = 1 - 0.414
Pd = 0.586
