You have 65% of your homework left to complete. What decimal and fraction represent the amount of homework you have finished?

1 answer:

7 0

Percentage of homework that is left to be completed = 65%
Then
The percentage of homework that is already done = (100 - 65) percent
   = 35 percent
   = (35/100)
   = 7/20
   = 0.35
So the amount of homework that has already been completed can be represented as 7/20 or o.35. Hope this is the answer you were looking for and i have helped you in this matter. Also i hope the procedure is easy enough for you to understand.

Thirty percent (30%) of the bulbs in a large box are defective. If 12 bulbs are selected randomly from the box, calculate the pr

AleksandrR [38]

The probability that exactly 6 are defective is 0.0792.

Given:

30% of the bulbs in a large box are defective.

If 12 bulbs are selected randomly from the box.

To find:

The probability that exactly 6 are defective.

Solution:

Probability of defective bulbs is:

$p=30\%$

$p=\dfrac{30}{100}$

$p=0.3$

Probability of non-defective bulbs is:

$q=1-p$

$q=1-0.3$

$q=0.7$

The probability that exactly 6 are defective is:

$P(x=r)=^nC_rp^rq^{n-r}$

$P(x=6)=^{12}C_6(0.3)^6(0.7)^{12-6}$

$P(x=6)=924(0.3)^6(0.7)^{6}$

$P(x=6)=0.0792478958$

$P(x=6)\approx 0.0792$

Therefore, the probability that exactly 6 are defective is 0.0792.

If a 6 mile race is divided into 1 3 of a mile sections, how many sections are there in the race?

arlik [135]

Hey there!

Here is your answer:

The proper answer to this question is "18 sections".

Reason:

Divide 6 and 1/3

6×3=18
1×1=1

18/1=18

Therefore it would be divided into 18 different sections.

If you need anymore help feel free to ask me!

Hope this helps!

Write a quadratic equation in standard form that has roots of -12 and 2

djyliett [7]

Answer:

x² + 10x - 24

Step-by-step explanation:

Given the roots are x = - 12 and x = 2 then the corresponding factors are

(x + 12) and (x - 2) and their product equals zero , that is

(x + 12)(x - 2) = 0 ← expand using FOIL

X² + 10X - 24 = 0
