We need an equation for this, theres no 'formula' for doing this (ignoring the quadratic formula, as that is a long-winded way of factorising a quadratic equation)
Answer:
1/5
Step-by-step explanation:
Slope formula = (y2-y1)/(x2-x1)
((-6)- (-9))/ ((9)-(-6)
(-6 + 9)/ (9 + 6)
3/15
1/5
Answer:
4x
Step-by-step explanation:
Answer: there are 8 quarters in the jar
Step-by-step explanation:
Let x represent the number of nickels that is inside the jar.
The total number of coins inside the jar is 20.
Probability is expressed as
Number of possible or favorable outcomes/total number of outcomes.
The probability of selecting a nickel is 0.6. This is expressed as
0.6 = x/20
Cross multiplying, it becomes
x = 20 × 0.6
x = 12
Since there are 12 nickels inside the jar, then the number of quarters would be
20 - 12 = 8
Answer:
Step-by-step explanation:
Given that,
The company makes 4 different sweat shirts
Each year they make 60,000 of each kind.
So, if they will make 60,000 sweat shirt for each brand and the company design 4 different brand.
So, number of brand is 4
n = 4.
Then,
1 brand = 60,000
Therefore, 4 brand = 60,000 × 4
4brand = 240,000 sweat shirts.
So, in a year the company will make 240,000 sweat shirts.
