Step-by-step explanation:
118 is the answer 238-120 = 118
They probably want 880 pesos, since they asked you do intermediate rounding
but a more accurate answer would be
883.20 pesos
To combine the functions, you'd substitute in 2.76r for y in 0.16y. This would give you 0.16(2.76r), which simplifies to 0.4416r, but they want you round this to the nearest hundredth, so its really 0.44r. Substitute in the 2000 for r and you get 0.44 * 2000 which is 880 pesos
They met 480 meters from the house.
<h3><u>Calculus</u></h3>
Given that Noah and his grandfather were returning home from a walk, and when they were 800 m away from the house, the grandfather said that he was thirsty, so Noah immediately ran home, got a bottle of water, and ran back to meet his grandfather who never stopped walking at a steady pace, to determine how many meters from the house did they meet if noah ran four times as fast as his grandfather walked, the following calculation must be made:
- 200 x 4 = 800 - 200 = 600
- 300 x 4 = 1200 - 800 - (800 - 300) = 100
- 325 x 4 = 1300 - 800 - (800 - 325) = -25
- 320 x 4 = 1280 - 800 - (800 - 320) = 480 - 480 = 0
Therefore, they met 480 meters from the house.

Answer:
a. B. Frequency is the number of times a particular distinct value occurs. Relative frequency is the ratio of the frequency of a value to the total number of observations.
b. A. A relative frequency is the same as a percentage expressed as a decimal.
Step-by-step explanation:
Frequency is the number of repetitions of a particular observation.
Relative Frequency is the ratio of the frequency of particular observation to the sum of frequencies of all the observations.
The percentage is the proportion of the whole.
Thus, In question (a)
Option B is the only correct answer.
and in question (b)
Option A is the only correct answer.
Answer:
5x² - 10x - 15
Step-by-step explanation:
Given
(5x + 5)(x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(x - 3) + 5(x - 3) ← distribute both parenthesis
= 5x² - 15x + 5x - 15 ← collect like terms
= 5x² - 10x - 15
