An algebraic expression that represent the worded expression would be (x is representing the unknown number) 3x-4, since the worded expression asks for "four less than three times a number" meaning you subtract 4 from the product of 3 and the unknown number.
Answer:
There are 40 outcomes in the sample space for the compound event.
Step-by-step explanation:
The total number of possible outcomes is equal to the product between the number of outcomes for each event.
The coin has 2 possible outcomes.
A twenty-part spinner has 20 possible outcomes (we assume that each part of the spinner corresponds to a unique outcome).
Then the total number of outcomes in the compound event is:
C = 2*20 = 40
There are 40 outcomes in the sample space for the compound event.
Answer:
A is better, you pay 0.015 less than option B.
Step-by-step explanation:
1 gallon = 128 oz so:
3 x 128 = 384 oz
9.60 / 384 = $0.025 per oz
16.00 / 400 = $0.04 per OZ
Answer:
h = 14.49 feet.
Step-by-step explanation:
From the attached figure,
Base = 14 ft
Height = h
Angle = 46°
We need to find the height of the main sail. To find it we can use trigonometry.
The relation between height, base and angle is given by :
So, the height of the main sail is 14.49 feet.
