3. Anna has a large bag of coins. After counting the coins, she recorded the counts in the table below. She then decided to draw

Sergio [31]

Answer:

(a) P = 0.2821

(b) P = 0.3718

(c) P = 0.7179

(d) P = 0.6538

(e) P = 0.4231

Explanation:

There is a total of 78 coins in the bag because:

22 + 27 + 11 + 18 = 78

From those 78 coins, 22 are quarters, so the probability that Anna obtains a quarter on the first draw is:

P = 22/78 = 0.2821

Since Anna replaces each coin before the next draw, the probability for each draw is independent. Therefore, the probability that Anna obtains a penny or a dime on the second draw is calculated as:

P = (18 + 11)/78 = 0.3718

Because there are 18 pennies and 11 dimes in the bag.

In the same way, Anna will obtain at most 10 cents worth of money if she obtains a penny, a dime, or a nickel. So, the probability is equal to:

P = (27 + 11 + 18)/78 = 0.7179

The probability that Anna does not get a nickel on the fourth draw is:

P = (22 + 11 + 18)/78 = 0.6538

Finally, Anna obtains at least 10 cents if he obtains a dime or a quarter, so the probability is:

P = (22 + 11)/78 = 0.4231

Therefore, the answers are:

(a) P = 0.2821

(b) P = 0.3718

(d) P = 0.6538

(e) P = 0.4231

Question

vazorg [7]

Slope-intercept form: y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

John gets a new job and receives a $800 signing bonus. After that, he makes $400 a day. [x = the number of days y = total earnings]

y = 400x + 800

[John earns $400 per day(x) plus a signing bonus(initial payment before working) of $800 = total amount of money he earns]

The slope is 400 or $\frac{400}{1}$

The y-intercept is 800

Estimate then find the product 5x4257

Dimas [21]

Well, to estimate we round to a simple number to work with, so we keep 5 the same. But, 4,257 is less simple, so it becomes 4,000.

5×4,000= 20,000
