Step-by-step explanation:

Total marbles = 12 + 30 + 20 + 10 + 8 = 80

Probability = 12 + 30 + 8 = 50

= 50 / 80 = 5 / 8

michelle and rosa are researching the deepest lakes in the united states for a school project. lake tahoe has a depth of 1,644 f
Hatshy [7]

Answer:

Rosa is closer to the correct depth.  

Step-by-step explanation:

To show that two measurements are nearly equivalent, we must convert one of the measurements to the other unit.

1 m = 3.281 ft

\text{Depth } = \text{1644 ft} \times \dfrac{\text{1 m}}{\text{3.281 ft}} = \textbf{501.1 m}

Neither is correct but Rosa is closer to the correct depth.

What are the restrictions on the domain of g o h?
umka21 [38]

g(x) = \sqrt{x-4} and h(x)= 2x-8

g o h is a composition function

First we find g o h

g o h is g(h(x))

We plug in h(x) in g(x)

We replace x  with 2x-8 in g(x)

g(h(x)) = g (2x-8) = \sqrt{2x-8-4} = \sqrt{2x-12}

g(h(x)) = \sqrt{2x-12}

To find domain we look at the domain of h(x) first

Domain of h(x) is set of all real numbers

now we look at the domain of g(h(x))

Negative number inside the square root is imaginary. so we ignore negative number inside the square root

So to find domain we set 2x - 12 >=0   and solve for x

2x - 12 >=0

add both sides by 12

2x >= 12

divide both sides by 2

x > = 6

Answer:

C  \frac{48}{70}

Step-by-step explanation:

Option C - \frac{48}{70} is incorrect because when multiplying the numerator and denominator of the fraction \frac{7}{10} by 7, you’re suppose to get \frac{49}{70}.
