Answer:
Option D
Step-by-step explanation:
<h2>Distance between two points</h2>
The y-value of the two points is unchanged. So, the line is parralel to x-axis.
The distance will be the diffrence between the x-co ordinates.

Exercer:
En face, [MH] est une hauteur du triangle MAT.
a.Calculer MH, puis HT.
b. Eva dit: "".
A-t-elle raison? Expliquer.
MA = 7,8cm
MT = 7,5cm
AH = 3cm
Answer:
La réponse d'Eva est incorrecte
Step-by-step explanation:
Nous résolvons les questions abive en utilisant le théorème de Pythagore
c² = a² + b²
a) Application de la formule ci-dessus:
Étape 1
Trouver MH
MA² = MH² + HA²
7,8² = MH² + 3²
MH² = 60,84-9
MH² = 51,84
MH = √51,84
MH = 7,2 cm
Étape 2
Résoudre pour HT
MT² = MH² + HT²
7,5² = 7,2² + HT²
HT² = 56,25 à 51,84
HT = √4,41
HT = 2,1 cm
b) La formule pour le périmètre du triangle MAT =
MA + MT + AH + HT
= 7,8 + 7,5 + 2,1 + 3 = 20,4 cm
Le périmètre du triangle MAT est de 20,4 cm
Donc, la réponse d'Eva est incorrecte

Answer:
The probability of getting a pair of red socks is 0.322
Step-by-step explanation:
According to the given data we have that A drawer contains 11 identical red socks and 8 identical black socks, hence, the total number of socks is 19, therefore, in order to calculate the probability of getting a pair of red socks we would have to use the following formula:
probability of getting a pair of red socks=11C2/19C2
probability of getting a pair of red socks=55/171
probability of getting a pair of red socks=0.322
The probability of getting a pair of red socks is 0.322
