In how many ways can carlos draw a blue or a green marble from a jar containing 30 blue marbles and 6 green marbles?

2 answers:

Total outcome = 30 + 6 = 36 [ 'cause it's a simple case when observer takes 1 object at a time]

So, option C is your final answer.

Hope this helps!

What is 6 kg 650g to the nearest 1/2kg

zysi [14]

Given:
6kg 650g
1/2 kg

1/2 kg is equal to 500 grams

1 kg = 1000 grams

We need to convert these figures from kg to g.

6 kg * 1000g/kg = 6*1000g = 6,000 g

6,000 g + 650 g = 6,650 g

6,650 g ÷ 500 g = 13.3 round off to 13

13 * 500 g = 6,500

6 kg 650 g is nearest to 6,500 g.

Allies plant has a height of 6meters. Radon’s plant grows 3/10 meters higher. How high does radon’s plant grow

kow [346]

The height of Radon plant is 6.3 meters

Solution:

Given that, Allies plant has a height of 6 meters

Radon’s plant grows $\frac{3}{10}$ meters higher

To find: Height of Radon plant

From given information,

Height of Allies plant = 6 meters

Height of radon plant = $\frac{3}{10}$ + Height of Allies plant

Substituting the known value,

$\text{ Height of radon plant} = \frac{3}{10} + 6\\\\\text{ Height of radon plant} = \frac{3+60}{10}\\\\\text{ Height of radon plant} = \frac{63}{10}\\\\\text{ Height of radon plant} = 6.3$

Thus Radon plant grows to height of 6.3 meters

Function g can be thought as scaled version of f(x)=x^2

Genrish500 [490]

Answer:

$g(x)=-\frac{1}{4} x^2$

Step-by-step explanation:

The graph is reflected against the x-axis, meaning it is negative

Next, we see that the graph is stretched out, therefor we have a fraction

The fraction is -1/4

You can check by inputting the x values into the x variable.

Four students wrote sequences during math class. Andre mc011-1.jpg Brenda mc011-2.jpg Camille mc011-3.jpg Doug mc011-4.jpg Which

maks197457 [2]

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

The common ration is obtained by dividing the a term by the preceding term.

Given that four students wrote sequences during math class with
Andre writing $-\frac{3}{4} ,\frac{3}{8} ,-\frac{3}{16} ,-\frac{3}{32} , . . .$
Brenda writing $\frac{3}{4} ,-\frac{3}{8} ,\frac{3}{16} ,\frac{3}{32} , . . .$
Camille writing $\frac{3}{4} ,\frac{3}{8} ,-\frac{3}{16} ,-\frac{3}{32} , . . .$
Doug writing $\frac{3}{4} ,-\frac{3}{8} ,\frac{3}{16} ,-\frac{3}{32} , . . .$

Notice that the common ratio for the four students is $- \frac{1}{2}$ .

For Andre, the last term is wrong and hence his sequence is not a geometric sequence.
For Brenda, the last term is wrong and hence her sequence is not a geometric sequence.
For Camille, her sequence is not a geometric sequence.
For Doug, his sequence is a geometric sequence with a common ratio of $- \frac{1}{2}$ .

Therefore, Doug wrote a geometric sequence.
