Answers

Answer 1

Answer:

Answer: The answer is provided below

Step-by-step explanation:

From the question, a box contains 20 miniature golf putt-putt balls out of which 10 are yellow, 6 are red, and the remaining 4 are pink.

The probability of picking a red golf ball will be:

= 6/20 × 100

= 600/20

= 30%

If the red ball is replaced, the probability of picking a yellow golf ball will be:

= 10/20 × 100%

= 50%

The solution is, Actual distance between point C and D is 900m.

What is ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

here, we have,

given that,

The distance between City A and City B is 500 miles.

A length of 1.9 feet represents this distance on a certain wall map.

City C and City D are 3.42 feet apart on this map.

Let, x be the actual distance between point C and D

Using ratio method,

1.9 : 500

3.42 : x

Now, we get,

1.9/500= 3.42/x

i.e. 3.42/x = 0.0038

or, x = 3.42/ 0.0038

or, x = 900

so, we get,

x=900

Actual distance between point C and D is 900m.

Suppose that a population begins at a size of 100 and grows continuously at a rate of 200% per year. Give the formula for calculating the size of that population after t years.

Answers

Answer:

y = 100(3)^t

Step-by-step explanation:

Use the formula y = P(1 + r)^t where y is the new amount, P is the starting amount, r is the rate as a decimal, and t is the time.

Plug in the values given:

y = 100(1 + 2)^t

y = 100(3)^t

Answer:

Step-by-step explanation:

y = 100(3)^t

Write an equation of the form y=mx for the pairs (0,0) and (1,4)

Answers

(0,0)(1,4)
slope = (4 - 0) / (1 - 0) = 4/1 = 4

y = mx + b
slope(m) = 4
(1,4)...x = 1 and y = 4
now sub and find b, the y int
4 = 4(1) + b
4 = 4 + b
4 - 4 = b
0 = b

ur equation is : y = 4x + 0 or just y = 4x
