if the probability of picking a pink jelly bean out of a bag is 4/15, what is the probability of not picking a pink jelly bean
Answers
Answer:
The probability of not picking a pink jelly bean: 11/15
Step-by-step explanation:
As we know that the maximum value of the probability of an event would always be 1.
The reason is that '1' is certain that something would happen.Given that the probability of picking a pink jelly bean out of a bag is 4/15.
Thus, the probability of not picking a pink jelly bean can be calculated by subtracting 4/15 from the maximum probability '1'.
i.e.
Probability of not picking a pink jelly bean = max probability - 4/15
= 1 - 4/15
= 11/15
Therefore, the probability of not picking a pink jelly bean: 11/15

what is the maximum number of cubes with side lengths of 1/2 cm that can fit into a right rectangular prism with base dimensions of 12 1/2 cm by 8 1/2cm and a height of 9 1/2cm?
Answers
Answer:
8075.
Step-by-step explanation:
Volume of the prism
= 12 1/2 * 8 1/2 * 9 1/2
= 25/2 * 17 / 2 * 19/2
= 8075/8 cm^3
The volume of the small cubes = (1/2)^3 = 1/8 cm^3
So the number required = 8075 / 8 / 1/8
= 8075*8 / 8
= 8075.

Solve for n in the following equation. A=P(1+n) show all your work
Answers
Answer:
A-1/P=n
Step-by-step explanation:
step 1. look at the parentheses and use inverse operations on both sides
A=P(1+n)
-1 -1
step 2. divide both sides by P
A-1=P(n)
/P /P
n= A-1/P
The value of n on solving the equation A = P (1 + n) is A / P - 1.
What is equation?An assertion that two mathematical expressions have equal values is known as an equation. An equation simply states that two things are equal. The equal to sign, or "=," is used to indicate it.
Given:
A = P (1 + n),
Here we can solve the parentheses by using the distributive property as shown below,
A = P × 1 + P × n
A = P + nP
Transform as shown below,
nP = A - P
n = (A - P) / P
n = A / P - 1
Thus, the value of n is A / P - 1.

plz help asap i will do brainliest!!! A car takes 4 hours to reach a destination travelling at the speed of 63 km/h. How long will it take to cover the same distance if the car travells at the speed of 56 km/h? Do these quantities (time and speed) vary directly or inversely? Find the constant of variation.
Answers
Answer:
A car takes 4 hours to reach a destination travelling at the speed of 63 km/h.
Speed = distance / time
Distance = speed × time
Distance it took the car, travelling for 4 hours to a destination at a speed of 63 kilometers per hour would be
4 × 63 = 252 kilometers.
if the car travels at a different speed of 56 kilometers per hour and the distance remains 252 kilometers, the time it takes will be
Time = distance / speed
= 252/56 = 4.5 hours
The time varies inversely with the speed. The more the speed, the lesser the time and the lesser the speed, the more the time.
Let speed = s and let time = t
s varies inversely with t
Introducing constant of inverse variation k, it becomes
s = k/t
When s = 56, t = 4.5
56 = k/4.5
k = 4.5 × 56 =252
This is the distance

A local restaurant only sells burgers and cokes. 3 burgers and 5 comes cost $17, while 6 burgers and 9 cokes cost $33. What’s the price of a burger?
Answers
Answer:
The price of a burger is $4 and that of cone is $1.
Step-by-step explanation:
Let the cost of burger is x and that of cone is y.
ATQ,
3x+5y = 17 ....(1)
And
6x + 9y = 33 ...(2)
Multiply equation (1) by 2.
6x + 10 y = 34 ...(3)
Subtract equation (2) from (3)
6x + 10 y-(6x + 9y) = 34 - 33
6x + 10 y-6x- 9y = 1
y = 1
Put the value of y in equation (1)
3x+5 = 17
3x = 12
x = 4
So, the price of a burger is $4 and that of the cone is $1.
