A jar contains 7 blue cubes, 4 blue spheres, 5 green cubes, and 6 green spheres. If you select an object at random, what is the

tia_tia [17]

The answer is A. 23/22.

The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens (there is OR in a sentence), you will use the addition rule. So, let's just add the probability that the object is green and the probability that the object is a cube.
There are in total 22 objects:
<span>7 blue cubes + 4 blue spheres + 5 green cubes + 6 green spheres = 22 objects.
</span>The probability that the object is green is 11/22 (because there are 11 objects
that are green (5 cubes and 6 spheres) of in total 22 objects).
The probability that the object is a cube is 12/22 (because there are 12 objects that are a cube (7 blue and 5 green) of in total 22 objects).

Thus, the probability that the object is green or a cube is:
$\frac{11}{12} + \frac{12}{12} = \frac{11+12}{12} = \frac{23}{12}$

1.) p^2+14p-38=0<br> what the vertex?

Lelu [443]

Answer:

vertex = (- 7, - 87)

Step-by-step explanation:

given a parabola in standard form : ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

p² + 14p - 38 is in standard form

with a = 1, b = 14, c = - 38, hence

$x_{vertex }$ = - $\frac{14}{2}$ = -7

substitute x = - 7 into the equation for corresponding value of y

y = (- 7)² + 14(- 7) - 38 = 49 - 98 - 38 - - 87

vertex = (- 7, - 87)

Maria has a portfolio consisting of 7 shares of stock A (purchased for $70 per share) and 4 shares of stock B (purchased for $10

Vlad [161]

Answer:

Hence, the expected rate of return after 1 year for Mary's portfolio is $0.17751$

Step-by-step explanation:

We have,

Purchase 7 shares of stock A for $70 per share and 4 shares of stock B for $100 per share then The expected rate of return after 1 year for Mary's portfolio.

Weight invested in stock A is $W_x=\frac{7\times 70}{7\times 70+4\times 100}$

$\Rightarrow W_x=\frac{490}{490+400}\\\Rightarrow W_x=\frac{490}{890}\\\Rightarrow W_x=\frac{49}{89}\\\Rightarrow W_x=0.5505$

Weight invested in stock B is $W_y=\frac{4\times 100}{7\times 70+4\times 100}$

$\Rightarrow W_y=\frac{400}{490+400} \\\Rightarrow W_y=\frac{400}{890} \\\Rightarrow W_y=\frac{40}{89} \\\Rightarrow W_y=0.4494$

The expected value of the rate of return $=W_x\times\;\text{expected rates of stock A}+W_y\times\;\text{expected rates of stock B}$

$=0.5505\times0.02+0.4494\times0.15$

$=0.01101+0.06741$

$=0.17751$
