1 hour is 550 miles how many miles would 1 hour and 42 minutes be

1 answer:

5 0

935 miles. This is because it takes 1 minute to travel 9.16667 miles. There is 102 minutes in 1 hour and 42 minutes, so you take 9.16667 * 102, this gets you 935 miles. Hope this helps.

Answer:

$P(X\geq 2)=1- P(X$

And using the probability mass function we can find the individual probabilities:

$P(X=0)=(8C0)(0.18)^0 (1-0.18)^{8-0}=0.2044$

$P(X=1)=(8C1)(0.18)^1 (1-0.18)^{0-1}=0.3590$

And replacing we got:

$P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366$

Then the probability that at least 2 disapprove of daily pot smoking is 0.4366

Step-by-step explanation:

Let X the random variable of interest "number of seniors who disapprove of daily smoking ", on this case we now that:

$X \sim Binom(n=8, p=0.18)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(X\geq 2)=1- P(X$

And using the probability mass function we can find the individual probabilities:

$P(X=0)=(8C0)(0.18)^0 (1-0.18)^{8-0}=0.2044$

$P(X=1)=(8C1)(0.18)^1 (1-0.18)^{0-1}=0.3590$

And replacing we got:

$P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366$

Then the probability that at least 2 disapprove of daily pot smoking is 0.4366

If a formula of a triangle is 18 = (h - 1) x 6 x .5 how would you get your answer?

V125BC [204]

Answer:

h = 7

Step-by-step explanation:

18 = (h - 1) × 6 × 0.5

simplify:

18 = 3(h - 1)

distribute the 3:

18 = 3h - 3

add 3 to both sides:

3h = 21

divide by 3:

h = 7

In two or more complete sentences, explain how to solve the cube root equation, .^3√x-1+2=0

Strike441 [17]

Answer:

$x= -7$

Step-by-step explanation:

We need to solve the following root equation:

$\sqrt[3]{x-1} + 2 = 0$

1. First, we need to add minus two to both sides of the equation:

$\sqrt[3]{x-1}= -2$

2. Elevate each side of the equation to the power of 3:

$x-1= -8$

3. Solve for 'x':

$x= -8 + 1$

$x= -7$

Therefore, the result is:

$x= -7$ ✔️
