Answer:

Step-by-step explanation:

For this problem you would first round everything. 9.03 becomes 9, 19.87 becomes 20, 3.11 becomes 3 and 4.97 becomes 5. You then just do the problem. 9 + 20 = 29, multiplied by 3 makes 87, 87 - 5 = 82.

Use the spinner to find each probability. If the spinner lands on a line it is spun again.

BlackZzzverrR [31]

Answer:

110 / 3.6 = 30.555

Chance for yellow is about 31%

Orange is 70/3.6= 19.4444444

Orange is about 19%

Red is 40/3.6=11.11

Red is about 11

We divide by 3.6 because 360 degrees /100 percent = 3.6

The decimals are repeating so it is infinite decimal places

Yellow is about 31% (30.555555 for exact)

Orange is 19%(19.4444444 for exact)

Red is 11%(11.11111 for exact)

Answer:

$P(x > 1\ and\ x < 2) = \frac{4}{25}$

Step-by-step explanation:

Given

$S = \{1,2,3,4,5\}$

$n(S) = 5$

Required

$P(x > 1\ and\ x < 2)$

$P(x > 1\ and\ x < 2)$ is calculated as:

$P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)$

Since it is a probability with replacement, we have:

$P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}$

For x > 1, we have:

$x > 1 = \{2,3,4,5\}\\$

$n(x > 1) = 4$

For x < 2, we have:

$x < 2 = \{1\}$

$n(x < 2) = 1$

$P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}$

becomes

$P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}$

$P(x > 1\ and\ x < 2) = \frac{4}{25}$

Slope = difference in y / difference in x
slope = 5 - 0 / 4 - 10
slope = 5 / -6
