Four biased coins, A, B, C and D are thrown.
The probability that each coin will land on Heads is shown in the table.
Coin Probability a) (i) Which coin is least likely to land on Heads?
А
0.66
(1)
0.066
(ii) Which coin is most likely to land on Heads?
С
(1)
60%
b) What is the probability that D will land on Tails?
(1)
B
D
Coin B is going to be thrown 4000 times.
c) Work out an estimate for the number of times
coin B will land on Heads.
(2)
Total marks: 5
Answer:
Please check explanations for answer
Step-by-step explanation:
Firstly, we need all the probability in the same decimal form
P(A) = 0.66
P(B) = 0.067
P(C) = 2/3 = 0.67
P(D) = 60/100 = 0.6
a) The least likely is the smallest value of decimal
This is 0.067 which is for coin B
most likely is the highest probability; this is C which is 2/3
b. Probability that D will land on tail is 1 - probability that it lands on head
= 1 - 0.6 = 0.4
c. Mathematically that is the product of the probability and the number of times it was thrown
That will be;
0.066 * 4000
= 264 times

You use Pythagorean theorem. Since the normal equation is [tex]a^{2} + b^{2} =c^{2}[/tex], you already have the [tex]c^{2}[/tex] and another side which can be [tex]a^{2}[/tex] or [tex]b^{2}[/tex].
Because you have the hypotenuse and a side , your equation looks like this now: [tex]7^{2} +b^{2} = 25^{2}[/tex]
and when you solve for be you just subtract [tex]25^{2} -7^{2}[/tex] to get 24.

a sphere has a volume of 905cm. what is the radius of the sphere rounded to the nearest whole number ?
Answer:
r = 6
Step-by-step explanation:
The value of radius of the sphere rounded to the nearest whole number is,
⇒ r = 6 cm
We have to given that,
Volume of a sphere = 905 cm
Since, We know that,
Volume of sphere = 4/3 (πr³)
Where, 'r' is radius of sphere.
Now, Substitute the given value, we get;
⇒ 905 = 4/3 (πr³)
⇒ 905 × 3 = 4 × 3.14 × r³
⇒ 2,715 = 12.56 × r³
⇒ r³ = 216.16
⇒ r = ∛216.16
⇒ r = 6 cm
Thus, The value of radius of the sphere rounded to the nearest whole number is,
⇒ r = 6 cm

9 ounces = how many pounds? in fraction form
Answer:
9/16 pounds
Step-by-step explanation:
1 pound = 16 ounces
With this information, we have make a proportion to find the number of pounds 9 ounces is
Let p = the number of pounds
16/1 = 9/p
Multiply both sides by 1 to get
16 = 9/p
Multiply both sides by p
16p = 9
Divide both sides by 16
p = 9/16
This fraction is in its simplest form and can't be simplified any more.
Answer:
9/16 is the answer brainliests
