P(A) = 0.7
P(B) = 0.8
P(A∩B) ⇒ When both event happens
P(A∩B) = 0.7 x 0.8 = 0.56
Answer: 0.56
Answer:
Step-by-step explanation:
Sin80° = opp/hyp
Sin80° = 21/y
ysin80° = 21
y = 21/sin80°
y = 21.3
Answer:
John's mother has the present age that is four less than the 8 times the present age of John.
If his mother has the age of 28 years now, then find John's present age.
Step-by-step explanation:
We have to write a word problem that would have the equation 8x - 4 = 28.
John's mother has the present age that is four less than the 8 times the present age of John.
If his mother has the age of 28 years now, then find John's present age.
So, if we consider the age of John as x years, then we will get the equation as 8x - 4 = 28. (Answer)
It is the commutative property since you can switch 5 and 4 around but still get the same answer (9).
Answer:
16.5mm to. 1 decimal place
Step-by-step explanation:
Please check attachment for diagrammatic representation of the triangle.
Since one of the angles of the triangle is 90, this means that we are dealing with a right angled triangle
To find the length of AC, we make use of pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the other two sides. The hypotenuse is the longest side of the triangle which we have as 17.88 mm
Mathematically therefore
17.8^2 = 6.6^2 + AC^2
AC^2 = 17.8^2 - 6.6^2
AC^2 = 283.28
AC = √(273.28)
AC = 16.53 mm
This is 16.5 to 1 decimal place
