14>7
Answer:
There must be 35 red marbles.
Step-by-step explanation:
This question can be solved using a rule of three.
A probability is the number of desired outcomes divided by the number of total outcomes.
The probability of randomly choosing a red marble is 7/9.
This means that for each set of 9 marbles, 7 must be red.
There are 45 marbles in total in the bag and each is equally likely to be chosen. Work out how many red marbles there must be.
How many red marbles out of 45?
7 red - 9 marbles
x red - 45 marbles

Simplifying by 9


There must be 35 red marbles.
Answer:
Probabilty of first component drawn defective= 0.1161
Probability of second component drawn defective= 0.1560
Step-by-step explanation:
Total component = 9
Defective component= 3
Non-defective component= 6
Probability of defective= 3/9
= 0.3333
Probabilty of non defective= 1-0.3333
= 0.6666
Probabilty of first component drawn is defective
= 9C1(0.333)¹(0.6666)^8
= 9(0.3333)(0.0387)
= 0.1161
Probabilty of second component is defective
= 8C1(0.3333)¹(0.6666)^7
= 8(0.3333)(0.0585)
= 0.1560
Answer:
6
Step-by-step explanation:
1+3=4
8÷4=2
Kindergarten = 2×1 =2
Other class = 2×3=6
Ratio of kindergarten classes to other classes is 2:6
Answer:
The equation is true when x = <u>4</u> because <u>6(4) = 24 </u>that is x=4 satisfies the given equation.
Step-by-step explanation:
Given: 
To find: x
Solution:
A equation is a statement that defines the equality of two expressions or numbers.

Divides both sides by 6

Therefore,
The equation is true when x = <u>4</u> because <u>6(4) = 24 </u>that is x=4 satisfies the given equation.
