P(3 or 6)
10/401/40.25Answer:
[tex]\sf \dfrac{1}{4}[/tex]
Step-by-step explanation:
Experimental probability
Calculated by dividing the number of times an event happens by the total number of trials in an actual experiment.
[tex]\textsf{Experimental Probability} = \dfrac{\textsf{Number of times an event happens}}{\textsf{Total number of trials}}[/tex]
Total number of trials = 10 + 6 + 4 + 8 + 6 + 6 = 40
Total number of times rolling a 3 or a 6 = 4 + 6 = 10
[tex]\textsf{Experimental Probability of rolling 3 or 6} = \sf \dfrac{10}{4}=\dfrac{1}{4}[/tex]

13 less than the product of 4 and a number n is 5
Answer:
(5 × 4) - 13 = 7
Step-by-step explanation:
Given that,
→ n = 5
Let's solve the problem,
→ x = n × 4
→ x = 5 × 4
→ [ x = 20 ]
Then 13 less than the product will be,
→ x - 13
→ 20 - 13 = 7
Therefore, the solution is 7.

Problem 6
It's not clear what the instructions are, but I'm assuming your teacher wants you to rationalize the denominator.
If so, then we could have these steps
[tex]\sqrt{\frac{3\text{x}}{7}}\\\\\frac{\sqrt{3\text{x}}}{\sqrt{7}}\\\\\frac{\sqrt{3\text{x}}*\sqrt{7}}{\sqrt{7}*\sqrt{7}}\\\\\frac{\sqrt{3\text{x}*7}}{(\sqrt{7})^2}\\\\\frac{\sqrt{21\text{x}}}{7}\\\\[/tex]
In the third step, I multiplied top and bottom by [tex]\sqrt{7}[/tex] so that the denominator can get rid of the square root.
Answer: [tex]\frac{\sqrt{21\text{x}}}{7}\\\\[/tex]======================================================
Problem 7
We'll follow the same idea for this problem.

Where m is nonnegative.
In the second to last step, I split up the root so I could use the rule [tex]\sqrt{x^2} = x \text{ when } x \ge 0[/tex]

3. The radioactive element carbon-14 has a half-life of 5750 years. A scientist determined that the bones from a mastodon had lost 70.3% of their carbon-14. How old were the bones at the time they were discovered?
Answer:
10,071 years
Step-by-step explanation:
If 'a' is the fraction remaining, it satisfies the equation ...
a = (1/2)^(t/5750)
Solving for t, we get ...
log(a) = log(1/2)×t/5750
t = 5750×log(a)/log(1/2) ≈ -19,101.09×log(a) . . . years
__
If 70.3% is lost, then 1 -0.703 = 0.297 is the fraction remaining. The age is estimated to be ...
-19,101.09×log(0.297) ≈ 10,071 . . . years
The bones were about 10,071 years old.

Answer:
£15.10
x + 20
64 counters in the bag
Total money = £21.30
Step-by-step explanation:
20p = £0.20
50p = £0.50
100p = £1.00
Total value:
⇒ 8 × 20p + 5 × 50p + 11 × £1 = 8 × 20p + 5 × 50p + 11 × 100p
= 160p + 250p + 1100p
= 1510p
= £15.10
-----------------------------------------------------------------------------------------------------
20 more than x: x + 20
-----------------------------------------------------------------------------------------------------
If one quarter of the counters in a bag are yellow, and there are 16 yellow counters in the bag:
⇒ total number of counters in the bag = 16 × 4 = 64
-----------------------------------------------------------------------------------------------------
Let x = number of 20p coins
Let y = number of 50p coins
Let z = number pf £1.00 coins
Given:
20p coins are worth £2.80⇒ 0.20x = 2.80
⇒ x = 2.80 0.20
⇒ x = 14
Therefore, there are 14 twenty pence coins.
Given:
One third of the coins are 20p coinsWe have calculated that there are 14 twenty pence coins, therefore:
⇒ total number of coins = number of 20p × 3
= 14 × 3
= 42
As the total number of coins is 42:
⇒ x + y + z = 42
⇒ 14 + y + z = 42
⇒ y + z = 42 - 14
⇒ y + z = 28
Therefore, the total number of 50p and £1 coins is 28.
Given:
10 more 50p coins than £1 coins⇒ y = z + 10
Substitute y = z + 10 into y + z = 28 and solve for z:
⇒ (z + 10) + z = 28
⇒ 2z + 10 = 28
⇒ 2z = 18
⇒ z = 9
Therefore, there are 9 one pound coins
total number of coins:
⇒ x + y + z = 42
substituting the found values of x and z:
⇒ 14 + y + 9 = 42
⇒ 23 + y = 42
⇒ y = 19
Therefore, there are 19 fifty pence coins
20p coins = 14
50p coins = 19
£1 coins = 9
Therefore, total money:
= 14 × 20p + 19 × 50p + 9 × 100p
= 280p + 950p + 900p
= 2130p
= £21.30
