Answer:

41.18% probability of drawing a white counter or a green counter

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

There are 3+10+4 = 17 counters.

Of those, 3+4 = 7 are white or green

7/17 = 0.4118

41.18% probability of drawing a white counter or a green counter

Sidana [21]

Answer:

1\frac{7}{20}

Step-by-step explanation:

1. Convert the mixed number to an improper fraction to match the rest of the problem (this just makes it easier for now, the answer will still be a mixed number)

-1\frac{4}{5} becomes \frac{9}{5}

2. Re-write the new equation. When there is a "+" in front of a set of parentheses the expression doesn't change aside from removing the plus signs.

The new equation becomes

\frac{9}{5} - \frac{1}{4} -\frac{1}{5}

3. Calculate. Just work out the new expression.

The answer is \frac{27}{20}

4. Convert to a simplified mixed decimal.

27 goes into 20 once with seven left over, making the answer 1\frac{7}{20}

Isabell is thinking of a even number between 234 and 250 the sum of the digits is double the digit in the ones place what is Isa
Lelu [443]

Answer:

246.

Step-by-step explanation:

Let the number be 2xy, then

2 + x + y = 2y    and y must be even because the whole number is even.

y = 2 + x .

Now x must be even because y is even.

The only 2 numbers which fit are x = 4 and y = 6 so the number is 246.

Checking: 2+4+6 = 12 and 12 = 2*6.

HELP ASAP, DUE AT 11:59<br><br> g(-5)=
Dovator [93]

Answer:

g(-5) = -6

Step-by-step explanation:

We need to find value of g(-5)

Looking at the graph in figure when g = -5, the value on the graph is -6 as it is highlighted with blue point.

because we have x = -5 so, we will look at graph that passes through x and y when x= -5, so we get y=-6

So, g(-5) = -6
