Answer:

There are four different possible outcomes: both coins are heads, the red coin is heads and the blue coin is tails, the red coin is tails and the blue coin is heads, or both coins are tails. Each outcome has equal probability. So the probability of both being heads is 1/4.

Please and thank you to whoever helps
Zepler [3.9K]

Answer:

  1131.0 m³

Step-by-step explanation:

Using the formula for the volume of a cylinder, fill in the appropriate values and do the arithmetic.

  V = πr²h

Since this formula needs the radius of the cylinder and you are given the diameter, you must divide the diameter by 2 to get the radius:

  r = d/2 = (12 m)/2 = 6 m

Then the volume is ...

  V = π(6 m)²(10 m) = 360π m³ ≈ 1131.0 m³ . . . . . rounded to tenths

Nina [5.8K]

Answer:

There are 28 dolls, 32 balls,  20 cars   for 80 total toys

Step-by-step explanation:

dolls : balls: cars: total

7           8          5    (7+8+5)

7           8           5        20

We have a total of  80  

80/20 = 4

We need to multiply each number by 4

dolls : balls: cars: total

7*4     8*4     5*4      20*4

28       32      20       80


There are 28 dolls, 32 balls,  20 cars   for 80 total toys

faltersainse [42]

Answer with explanation:

It is given that, there is positive correlation between drinking coconut milk and eating potato chips.

→Correlation coefficient is denoted by r.

→The value of r lies between , -1 and 1 which is represented as , -1 ≤r≤1.

→Correlation that is relation between two variables is said to be strongly positive, if r is equal to 1, and it is said to be strongly weak, if it is equal to -1 , and said to have no association if r=0.

→ The meaning of positive correlation is that value of r, is greater than >0.8 but less than 1.

The two variables which are positively correlated ,can have following relationship.

1. With increase in one other increases.

2.With decrease in one other decreases.

3. Slope will be a linear that is a straight line not passing through origin.
