Answer:

The independent probability is P(1st and 2nd spin) = 2.78 %

Step-by-step explanation:

A spinner has an equal chance of landing on each of its six numbered regions so each spin has 6 possible outcomes.

Recall that the probability is given by

P = number of outcomes we are interested in/total number of possible outcomes

The number of interest outcomes = 1 ( landing in region one or three)

These two spins are mutually exclusive meaning that they are independent of each other, the probability of landing in region one doesn't affect the probability of landing in region three.

First spin:

The Probability of landing in region one is = P(1st spin) = 1/6

Second spin:

The Probability of landing in region three is = P(2nd spin) = 1/6

P(1st and 2nd spin) = P(1st spin)*P(2nd spin)

P(1st and 2nd spin) = 1/6*1/6

P(1st and 2nd spin) = 1/36

P(1st and 2nd spin) = 2.78 %

Which set of rational numbers is arranged from least to greatest? 1 over 5, −1.4, negative 1 over 2, 3 3, negative 1 over 2, −1.

Mars2501 [29]

Answer:

Option 4 - $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Step-by-step explanation:

To find : Which set of rational numbers is arranged from least to greatest?

Solution :

The set of rational numbers are

$3,\ \frac{1}{5},\ -1.4,\ -\frac{1}{2}$

Writing all number in one form,

$\frac{1}{5}=0.2$

$-\frac{1}{2}=-0.5$

Now, -1.4<-0.5<0.2<3

From least to greatest the set of natural numbers are

$-1.4$

So, $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Therefore, option 4 is correct.

Answer:

Option A = 7.5 cups

Step-by-step explanation:

Given : Suppose you're making a soup that uses 5 cups of chicken broth and $\frac{3}{4}$ teaspoons of corn starch for 8 servings. You need to make 12 servings of the soup, so you'll need $1\frac{1}{8}$ teaspoons of corn starch.
