On any day, the probability of rain is 0.3. The occurrence of rain on any day is independent of the occurrence of rain on any ot

Sunny_sXe [5.5K]

Answer:

0.47178 = 47.178%

Step-by-step explanation:

Put simply, this question is asking the probability of having rain atleast twice in the next 5 days. The easiest way that comes to mind is reverse count - find the probability of it not happening. There are two cases for this:

Raining only once:

This has a .7^4 * 0.3 * 5 chance

Raining no times:

This has a .7^5 chance

Adding these together you get 0.52822

This is the inverse probability, so to find the actual probability, subtract it from 1.

P = 0.47178

Black_prince [1.1K]

Answer:

Tristan has a 17/24 lb fraction of a pound of grapes now.

Step-by-step explanation:

Given

The number of grapes Tristan had at home = 1/3 lb

The number of grapes Tristan had at the store = 3/8 lb

To determine

What fraction of a pound of grapes does Tristan have now?

In order to get the total fraction of a pound of grapes, all we need is to add the number of grapes Tristan had at home and the number of grapes Tristan had at the store.

i.e.

Current number grapes = 1/3 + 3/8

Least Common Multiple of 3, 8: 24

Adjust fractions based on L.C.M

= 8/24 + 9/24

Apply the fraction rule: $\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$

= (8 + 9) / 24

= 17/24 lb

Therefore, Tristan has a 17/24 lb fraction of a pound of grapes now.

Solve the inequality. use interval notion to state the solution (x+3)^2>2(x^2+7)

OleMash [197]

Answer:

we conclude that:

$x^2+6x+9>2x^2+14\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:1$

Hence, (1, 5) is the solution in interval notation.

Please also check the attached graph.

Step-by-step explanation:

Given the inequality expression

$\left(x+3\right)^2>\:2\left(x^2+7\right)$

as

(x + 3)² = x² + 6x + 9

2(x² + 7) = 2x² + 14

so

$\:x^2+6x+9\:>\:2x^2+14$

rewriting in the standard form

$-x^2+6x-5>0$

Factor -x² + 6x - 5: - (x - 1) (x - 5)

$-\left(x-1\right)\left(x-5\right)>0$

Multiply both sides by -1 (reverse the inequality)

$\left(-\left(x-1\right)\left(x-5\right)\right)\left(-1\right)$

Simplify

$\left(x-1\right)\left(x-5\right)$

so

$1$

Therefore, we conclude that:

$x^2+6x+9>2x^2+14\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:1$

Hence, (1, 5) is the solution in interval notation.
