Answer:
The probability of selecting a family with exactly one male child is 1/4 or 0.25.
Step-by-step explanation:
Given in the question,
possible outcomes for the children's genders
{FFFF, FFFM, FFMF, FMFF, MFFF, MFFM, MFMF, MMFF, FFMM, FMFM, FMMF, FMMM, MFMM, MMFM, MMMF, MMMM}
= 16
To find,
the probability of selecting a family with exactly one male child
<h3>Probability = favourable outcomes / possible outcomes</h3>
favourable outcomes = {FFFM, FFMF, FMFF, MFFF}
= 4
Probability = 4 / 16
= 1 / 4
= 0.25
X - 7 > 10
x > 10 + 7
x > 17
3x < = 21
x < = 21/3
x < = 7
5a - 2 < 18
5a < 18 + 2
5a < 20
a < 20/5
a < 4

t > = -2
Answer:
line mo
Step-by-step explanation:
Because the triangle are congrument
RST and MNO are the triangle
RT is a line in the RST triqangle
it is equal to the MO line in MNO
Answer:it’s going to be b
Step-by-step explanation:
Answer:
21. ΔUYZ <u>Obtuse</u>
22. ΔBCD <u>Right or Rectangle</u>
23. ΔADB <u>Acute</u>
24. ΔUXZ <u>Acute</u>
25. ΔUWZ <u>Right or Rectangle</u>
26. ΔUXY <u>Equiangular and acute</u>
Step-by-step explanation:
We need to classify each triangle by its angles.
Acute: They have 3 acute angles (less than 90 degrees).
Rectangle: The inner angle A is straight (90 degrees) and the other 2 angles are sharp. The sides that form the right angle are called legs (c and b), the other side hypotenuse.
Obtuse: The inner angle A is obtuse (more than 90 degrees). The other 2 angles are acute.
ΔUYZ Obtuse The inner angle Y is obtuse (more than 90°).
ΔBCD Right or Rectangle The inner angle C is straight (90°).
ΔADB Acute It has 3 acute angles (less than 90°).
ΔUXZ Acute It has 3 acute angles (less than 90°).
ΔUWZ Right or Rectangle The inner angle W is straight (90°).
ΔUXY Equiangular and acute Which means all the inner angles are equal (60°).
