6+8+5=19
Probability= 8/19=0.42= 42% of picking green.
The answer:
first of all, we should know that the expression of a vector V (a, b) can be written as follow:
V = r (Vx i + Vyj), where r is the length of the vector, it is r = sqrt(V²x + V²y)
Vx is the component lying on the x-axis and Vy on the y-axis
<span>v ⃗ lies in Quadrant II, means Vx is less than 0 (negative)
</span>
so Vx= -r sin30° and Vy= rcos30°
r= <span>‖v ⃗ ‖=4√3
</span>
so we have v = - 4√3sin30° i + 4√3 cos30° j
the components are
v(- 4√3sin30°, 4√3 cos30°) = (-2√3, 4√3 cos30°)
Answer:
10
Step-by-step explanation:
h(x)=4x-2 h(x)=3
h(3)=4(3)-2 substitute
h(3)=12-2 multiply
=10 subtract
Is 243 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 243 is about 15.588. Thus, the square root of 243 is not an integer, and therefore 243 is not a square number.
Investment made in one of the account is $1000 and investment made in other account is $3000.
Further, it is given that interest rate in both the accounts is same and the period for which the amount is invested is also same.
Interest = Principal * Rate * Time /100
So in case of 1st account,
Interest = 1000 * Rate * Time/100
and for the second account,
Interest = 3000* Rate * Time /100
So, comparing above two interest, it is evident that $3000 account will earn three times the amount of interest.
Hope it helps.
Thank you ..!!
