Answer:
c. 12%
Step-by-step explanation:
40% of the beads are spears, you can convert it to 0.4
30% of the spheres are blue, you can convert it to 0.3
=> probability choosing blue sphere = (0.4 * 0.3)*100(%) = 12%
My explaination may not really clear but the answer is correct. Hope this help!
f(x)= -2x-3
Step-by-step explanation:
Step 1:
Let the sequence given here is -5, -7, -9, -11, -13 ......
Here the first term (a₁) of sequence is -5
And the common difference between the numbers in the sequence is
d= (-7-(-5)) = -7+5 = -2
Let the number of terms be x
Step 2;
To find the sequence function basic arithmetic sequence formula is
aₙ = a₁ + d( x-1)
Applying the values we get
f(X) = -5 + ((-2)(X-1))
on simplification
f(X) = -5 + (-2X+2)
f(X)= -5+2-2X
f(X)= -3-2X
Answer:
15
Step-by-step explanation:
5+5+5=15
For this case we must find the quotient of the following expression:

We can rewrite the expression as:

By definition of division of powers of the same base, we place the same base and subtract the exponents:

So:

Answer:

Answer: = £135
Step-by-step explanation:
Original price = 100%
Percentage increase = 20%
New price = 100% + 20% = 120%
If 120% = £162
What about 100% = ?
= (100 x 162) ÷ 120
= 16200 ÷ 120
= £135.
