Answer:
x = 4, -1.5
Step-by-step explanation:
2x² - 5x - 12 = 0
2x² - 8x + 3x - 12 = 0
2x(x - 4) + 3(x - 4) = 0
(x - 4)(2x + 3) = 0
x = 4, -1.5
The graph cuts the x-axis at x = 4 and x = -1.5
The two triangles are similar.
40/x = 32/4
x = 5
Answer:
a) Expected value of the mean = 0.793 percent
b) Standard error = 0.019 percent.
Step-by-step explanation:
Given
mean = μ = 0.793 percent
Standard deviation = σ = 0.114 percent
a) The sample mean is related to the population mean through
μₓ = μ = 0.793 percent
Hence, the expected value of the sample mean = 0.793 percent.
b) The standard error is given as
Standard error = σ/√n
where n = sample size = 36
Standard error = (0.114/√36)
Standard Error = 0.019 percent.
Hope this Helps!!!
Answer:
<h2>9498.5 m</h2>
Step-by-step explanation:
We know that the Circumference = 3454 cm
And we also know that the formula for the Circumference of Circle is,
So we can put the equation this way,
So we can solve for 'r'
Now we have radius and we can solve for the area of the circle,
We can convert this to meter,
9498.5 m
I am not sure if this is correct just let me know thanks :)
D: the basketballs.
Since there are 4 times as many students then basketballs, Basketballs are the variable (x) and the amount of students per basketball is 4.
