Answer:

11.6

Step-by-step explanation:

<u>Solving with steps as below:</u>

31*r+1.1*(35−31)*r = 410.64
31r + 1.1*4r = 410.64
31r + 4.4r = 410.64
35.4r = 410.64
r = 410.64/35.4
r = 11.6

<u>Answer is:</u> r =11.6

Solve 10 ^(2x+9)=290 Express in terms of natura logarithms

GenaCL600 [577]

Use following log property:
$ln( a^n) = n ln (a)$

Take log of both sides
$ln (10^{2x+9}) = ln (290) \\ \\ (2x+9) ln (10) = ln (290)$

Distribute left side, isolate 'x'
$2 ln (10) x + 9 ln(10) = ln (290) \\ \\ x = \frac{ln (290) - 9 ln(10)}{2 ln(10)}$

Suppose that the commuting time on a particular train is uniformly distributed between 42 and 52 minutes. Bold a. What is the pr

nikdorinn [45]

Answer: 0.2

Step-by-step explanation:

Given: The commuting time on a particular train is uniformly distributed over the interval (42,52).

∴ The probability density function of X will be :-

$f(x)=\dfrac{1}{b-a}\\\\=\dfrac{1}{52-42}=\dfrac{1}{10}, 42$
