Answer:
The correct answer would be [tex]a=\sqrt{c^2-b^2}[/tex]
Step-by-step explanation:
given [tex]a^2+b^2=c^2[/tex] we want to solve for a
How?
We can do this by using basic algebra ( isolating the variable (a ))
Step 1 subtract [tex]b^2[/tex] from each side
[tex]a^2+b^2-b^2=a^2\\c^2-b^2=c^2-b^2[/tex]
now we have [tex]a^2=c^2-b^2[/tex]
step 2 take the square root of each side
[tex]\sqrt{a^2} =a\\\sqrt{c^2-b^2} =\sqrt{c^2-b^2}[/tex]
we're left with [tex]a=\sqrt{c^2-b^2}[/tex]
Hence your answer is A

A density graph for all of the possible temperatures from 60 degrees to 160 degrees can be used to find which of the following?
A.The probability of a temperature from 30 degrees to 120 degrees
B.The probability of a temperature from 90 degrees to 180 degrees
C.The probability of a temperature from 30 degrees to 90 degrees
D.The probability of a temperature from 90 degrees to 120 degrees
Answers
Answer: 90 degrees to 120
Step-by-step explanation:
The probability of a temperature from 90 degrees to 120 degrees.
What is Probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Experiment: A trial or an operation conducted to produce an outcome is called an experiment.
Sample Space: All the possible outcomes of an experiment together constitute a sample space. For example, the sample space of tossing a coin is head and tail.
Favorable Outcome: An event that has produced the desired result or expected event is called a favorable outcome. For example, when we roll two dice, the possible/favorable outcomes of getting the sum of numbers on the two dice as 4 are (1,3), (2,2), and (3,1).
Trial: A trial denotes doing a random experiment.
Given:
Temperatures from 60 degrees to 160 degrees.
As, per the situation the probability will lie between 60 degree to 160 degree.
Hence, The probability of a temperature from 90 degrees to 120 degrees.

Answer:
Area of Grass = 6 m²
Area of Cement = 24 m²
Area of Grass and Cement Together = 30 m²
Step-by-step explanation:
Area of Grass = 3m × 2m = 6m²
Area of Cement = (6m × 5m) - 6m² = 30m² - 6m² = 24m²
Area of Grass and Cement Together = 6m² + 24m² = 30m²

Determine another point on the line given two points on the line. (-2, 9), (2, -1)
Answers
Answer:
(4,-6)
Step-by-step explanation:
1) First, let's find the slope of the line between the two points. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], substitute the x and y values of (-2,9) and (2,-1) into it, then solve:
[tex]m = \frac{(-1)-(9)}{(2)-(-2)}\\m = \frac{-1-9}{2+2} \\m =\frac{-10}{4} \\m = -\frac{5}{2}[/tex]
So, the slope of the line is [tex]-\frac{5}{2}[/tex].
2) Now, using that slope, let's find another point on the line. You can do this by drawing the two points on a graph (picture below). Now, remember that the slope is [tex]\frac{rise}{run}[/tex]. So, starting from any of the two points (I chose (2,-1), as seen below) count 5 units down, then 2 units to the right. This gives an answer, (4,-6).

There are 10 red apples and 12 green apples in a basket. If Vinta randomly selects 3 apples from
the basket, what is the probability they will all be green apples?
Answers
Answer: 1/7
Step-by-step explanation: 12/22 • 11/21 • 10/20
The probability they will all be green apples is 0.142 if there are 10 red apples and 12 green apples in a basket.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
As we know,
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
It is given that:
There are 10 red apples and 12 green apples in a basket. If Vinta randomly selects 3 apples from the basket.
Total outcomes = number of ways of selecting fruits in the basket
Total fruits = 10 + 12 = 22
Total number of outcomes = C(22, 3) = 1540
Total number of favourable outcomes = C(12, 3) = 220
Probability = 220/1540
Probability = 0.142
Thus, the probability they will all be green apples is 0.142 if there are 10 red apples and 12 green apples in a basket.

Step-by-step explanation:
Answer:
Step-by-step explanation:
First put the numbers from least to greatest: 1, 2, 2, 2, 3 2 is the mean.
Then you determine the distance each data value is from the mean.
1, 2, 2, 2, 3
1, 0, 0, 0, 1
Calculate the mean of the distances: 1 + 0 + 0 + 0 + 1 = 2
Then divide: 2 divided by 5 = 0.4
So your answer is 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds

3² + b² = 5²
9 + b² = 25
b² = 25 - 9
b² = 16
b = 4m
∴ The distance between the ladder and the bottom of the slide is 4m.

Answer:

Step-by-step explanation:
In the equation, 8.5 will represent how much money Oscar earns per hour, and the x represents how many hours he works. The inequality sign shows that the sum of 8.5x and 100 has to be at least 397.50 (397.50 and up), so H and J are automatically wrong. If Oscar had given his brother 100 dollars, there would be a subtraction sign, but there is an addition sign instead, meaning he gained 100 dollars that did not come from his job. It would be the most logical to say that his brother had given it to him, so G is the correct answer.
