Answer:
No, he is wrong
Step-by-step explanation:
To find that probability, the first thing we need to know is the total number of coins present.
Mathematically, that would be 3 + 2 + 3 = 8
Since there are 8 coins, the probability of selecting a dime is number of dimes/total number of coins = 2/8 = 1/4
The probability we want to work with is that the two selections are dimes, let’s say with replacement.
That means; first selection is a dime and second selection is also a dime
Mathematically in probability, the term and means that we have to multiply our results.
So the probability that both are dimes would be 1/4 * 1/4 = 1/16
And this makes his answer wrong
To find unit rate you divide the numerator and the denominatorof the given rate.
Given:
bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.
Let us use the Pythagorean theorem.
a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft
The height of the wall is 40 ft.
