Value of side length is 3 cm
Give that;
Area of square = 9 cm²
FInd:
Value of side length
Computation:
We know that,
⇒Area of square = Side²
BY putting value into formula
⇒ Side² = 9
⇒ Side² = 3²
⇒ Side = 3
So,
Value of side length = 3 cm

Answer:
see below
Step-by-step explanation:
a) If random variables X and Y are simple, then their linear combination aX + bY is also simple.
b) If X₁ and X₂ are simple, then X₁ + X₂ and X₁ ∧ X₂ are also simple.
c) The representation of a simple random variable X is not unique. There can be different sets of {Aᵢ} and corresponding scalars {bᵢ} that represent the same X.
d) If the sets Aᵢ are known to be disjoint, then X can take as many unique values as there are disjoint sets {Aᵢ}.
e) A random variable X is simple if and only if it takes a finite number of values.
f) The expected value E[X] is well-defined for a simple random variable X, regardless of its representation. It can be calculated using the formula E[X] = ∑ᵢ bᵢ P(Aᵢ) or E[X] = ∑ᵢ cᵢ P(Bᵢ), where {Aᵢ} and {Bᵢ} are sets and {bᵢ} and {cᵢ} are scalars representing X.
Answer:
2
Step-by-step explanation:
Take any 2 points on the graph,
(50, 10) & (90, 90)
Use the slope formula:
= (90-10)/(90-50)
= (80)/(40)
= 2
Hence, the slope is 2.
Feel free to mark this as brainliest! :D
Step-by-step explanation:
You have given a point (1, -5), a slope of 5, and the line passes through the point (-1, -3). You can use this information to find the equation of the line.
The equation of a line in point-slope form is:
y - y1 = m(x - x1)
Where (x1, y1) is a point on the line, and m is the slope.
Using the given point (1, -5) and the slope m = 5, you can plug these values into the equation:
y - (-5) = 5(x - 1)
Now, simplify:
y + 5 = 5(x - 1)
To put it in slope-intercept form (y = mx + b), expand and solve for y:
y + 5 = 5x - 5
Subtract 5 from both sides:
y = 5x - 5 - 5
y = 5x - 10
So, the equation of the line with a slope of 5 that passes through the point (1, -5) is:
y = 5x - 10
B. what is the probability a randomly selected score is less than 32.8?
C. What is the probability a randomly selected score is Between 25.6 and 32.8?
Answer:
a. 0.1587
b. 0.8849
c. 0.1814
Step-by-step explanation:
a. Given that
-The probability a randomly selected score is greater than 30.4 is calculated as:
Hence, the probability of a score greater than 30.4 is 0.1587
b. Given that
The probability a randomly selected score is less than 32.8 is calculated as:
Hence, the probability that a randomly selected score is less than 32.8 is 0.8849
c. The probability that a score is between 25.6 and 32.8 is calculated as follows:
Hence, the probability is 0.1814
I think the answer is 24/80 because you have multiplied the denominator by 8 to get to ?/80 from 3/10. Therefore, you need to multiply 3 by 8 also, which when you do, you get 24/80
Answer:
-0.3 Or 3.3
Step-by-step explanation:
-2y^2 + 6y + 2 = 0
X = -6 + 7.21/-4 or -7 - 7.21/-4
X = -0.3 or X = 3.3
