Answer:
Step-by-step explanation:
3) ΔABC ≅ ΔDEF
AB = ED {Corresponding parts of corresponding triangles are equal}
6y - 4 = 4y +2
add 4 to both sides
6y - 4 + 4 = 4y + 2 + 4
6y = 4y + 6
subtract 4y from both sides
6y - 4y = 4y + 6 - 4y
2y = 6
Divide by 2
y = 3
AB = 6y - 4 = 6*3 - 4 = 18 - 4 =14
AB = 14
ΔABC ≅ ΔDEF
∠A = ∠D {Corresponding parts of corresponding triangles are equal}
5x + 2 =87
5x = 87 - 2
5x = 85
x = 85/5
x = 17
In ΔDEF,
∠D + ∠E + ∠F = 180° {SUM OF ALL ANGLES OF TRIANGLES}
87 + 42 + ∠F = 180
129 + ∠F = 180°
∠F = 180 - 129
∠F = 51°
ΔABC ≅ ΔDEF
∠C = ∠F {Corresponding parts of corresponding triangles are equal}
3y = 51
y= 51/3
y = 17
The answer is because precision refers to the closeness of the measured data with each other. Having a low range means that the data are not widely distributed. Range is the difference of the largest value to the smallest value. When the least data is very close to the largest data, then the range will be low or close to zero.

Answer: The probability that both cards that are drawn are hearts is
1
17
.
Explanation:
First off, know that there are 13 heart cards in the deck of 52 cards. Therefore, the chance of pulling a single heart card is
13
52
. Let's say we do pull a heart card. Since there is no replacement for the heart card taken out of the deck, we now have 12 heart cards out a deck of 51 cards. The chance of pulling out a heart card in now
12
51
. To find the probability that both cards drawn out are hearts, multiply the two fractions together:

13
52
)
