5x is a short term for 5x X, so u just need to do 30/5 and that is what x equals.
Answer:
The geometric mean of the measures of the line segments AD and DC is 60/13
Step-by-step explanation:
Geometric mean: BD² = AD×DC
BD = √(AD×DC)
hypotenuse/leg = leg/part
ΔADB: AC/12 = 12/AD
AC×AD = 12×12 = 144
AD = 144/AC
ΔBDC: AC/5 = 5/DC
AC×DC = 5×5 = 25
DC = 25/AC
BD = √[(144/AC)(25/AC)]
BD = (12×5)/AC
BD= 60/AC
Apply Pythagoras theorem in ΔABC
AC² = 12² + 5²
AC² = 144+ 25 = 169
AC = √169 = 13
BD = 60/13
The geometric mean of the measures of the line segments AD and DC is BD = 60/13
Answer: 0.595
Step-by-step explanation:
Independently expriment:
P(A n B) = p(A) × p(B)
Therefore
P(E1 n E2) = P(E1) × P(E2)
P(E1 n E2) = 0.85 × 0.70 = 0.595
So the probabilty that both experiment succeed is : 0.595
product means multiplication
88 is the product of 8 multiplied by a number
so 88/8 =11
jenny's score is 11
