Answer:

500

Step-by-step explanation:

If 1% is 2.5 then 100% is 250. Since 250 is half of a number, you went then multiply by 2 to double that number which is 500.

Help me if you understand thanks sm

First, find the slope of the line using the formula for slope:

m = (y2 - y1) / (x2 - x1)

m = (4 - (-2)) / (-3 - 2) = -6/5

Then, use the point-slope formula using a point that you were given and the slope that you calculated.

y - y1 = m(x - x1)

y - 4 = (-6/5)(x + 3)

Then, simply get y alone.

y = (-6/5)x + 2/5

He rain caused the river to ride a total of 6 2/3 inches. The river was rising at an average of 2/3 of an inch each hour. How ma

Kobotan [32]

To find out how many hours it rained, divide the total rise in the river by the amount it rose every hour.

$\sf 6\dfrac{2}{3}\div\dfrac{2}{3}$

First convert the mixed number into an improper fraction. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes our new numerator, and we keep the denominator the same:

$\sf\dfrac{20}{3}\div\dfrac{2}{3}$

When dividing fractions we flip(the reciprocal) the one we're dividing by and multiply:

$\sf\dfrac{20}{3}\times\dfrac{3}{2}$

Multiply the numerators and denominators together:

$\sf\dfrac{60}{6}$

Simplify by dividing:

$\boxed{\sf 10}$

So it rained for 10 hours.

3. Calvin has a bucket of marbles. The table shows the number of marbles of each color Color Amount Red Blue 3 Yellow 4 Green Ca

dalvyx [7]

The false statement is (c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

<h3>What are probabilities?</h3>

Probabilities are used to determine the chances of events

The table entry is given as:

Red - 2
Blue - 3
Yellow - 4
Green - 3

From the list of options, the false statement is

(c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

This is so because:

Blue or Yellow = 3 + 4 = 7
Red or Green = 2 + 3 = 5

Notice the count of blue or yellow marbles (7) is greater than the number of red or green marbles (5)

This means that, the probability of selecting a blue or yellow marble is greater than the probability of selecting a red or green marble.
