Answer: hope this helps

Step-by-step explanation:

5 (x + 8)

Root:

x = -8

Derivative:

d/dx(2 x + 46 + 3 x - 6) = 5

Indefinite integral:

integral(40 + 5 x) dx = (5 x^2)/2 + 40 x + constant

Can someone help? If b/a=c/b=d/c=2/3, find a:b:c:d.

blagie [28]

Answer: a:b:c:d = 16:24:30:40

You can also divide the ratio by 2 because all terms have 2 in common. Which would be a:b:c:d = 8:12:15:20

A sociologist randomly selects single adults for different groups of three, and the random variable x is the number in the group

Bas_tet [7]

Answer:

This data is not a probability distribution

The reason sum of the probabilities is not equal

∑ P(X=x) ≠ 1

Step-by-step explanation:

Explanation:-

Given data

x 0 1 2 3

p(x) 0.091 0.334 0.408 0.166

Discrete distribution :-

Probability distribution of a random variable is the set of its possible values together with their respective probabilities. Suppose X is a discrete random variable with possible outcomes (values) x₁ , x₂ , x₃ ,......... The probability of each possible outcome

$p_{i} = P(x=x_{i}) = p(x_{i}) for I= 1,2,3......$

If the numbers $p(x_{i}) , I =1 ,2,3,.....$ satisfy the two conditions

i) $p(x_{i}) \geq 0 for all values of i$

ii) ∑P(X=x) =1

Given data condition(i) satisfied $p(x_{i}) \geq 0 for all values of i$

but the condition (ii) is not satisfied

0.091+0.334+ 0.408+ 0.166 = 0.999

sum off all probabilities is not equal to one

Conclusion:-

The given data is not probability distribution

Which expressions are equivalent to 3x + 2(x − 1) − 4? A.) 3x + 2x - 2 - 4 B.) 5x - 6 C.) 3(x - 4) D.) 3(x + 2) - 6 E.) 6(x - 1)

sasho [114]

Multiplication takes precedence
Execute the command multiplication bracket

3x + 2* (x - 1) - 4 =
3x + 2* x + 2* (-1 ) - 4 =
3x + 2x - 2 - 4 =

We reduce similar words

3x + 2x - 2 - 4 =
5x - 6
