Kazeer [188]3 years ago
4 0

Step-by-step explanation:

To do this we need to calculate the slope of each side. If we can show that the slopes of the opposite sides are the same, then the opposite sides are parallel. The slopes of the opposites were the same, so ABCD is a parallelogram.

At an ice cream shop, there are 3 different flavors of ice cream and 10 different toppings. What is the probability of the next
ANTONII [103]

Answer:

1/ 30

Step-by-step explanation:

probability of selecting one thing out of n different thing is 1/n

There are three flavors of ice cream

Therefore the number of of ways to select a ice cream is 3(sample space).

one of the flavor is strawberry

probability of selecting strawberry = 1/3

*****************************************************************

There are 10 flavors of toppings

Therefore the number of of ways to select a toppings is 10(sample space)..

one of the flavor is sprinkles

probability of selecting sprinkles = 1/10

*******************************************************************

probability of occurrence of two mutually independent event P(A) and P(B) simultaneously is P(A) * P(B) .

Mutually independent events are those event in which occurrence of one event does not affect the occurrence of other event.

In the problem stated selection of flavor and toppings are independent events .

Now probability of selecting strawberry ice cream with sprinkles = probability of selecting sprinkles*probability of selecting strawberry

= 1/3 *1/10

= 1/30

Hence probability of the next customer ordering strawberry ice cream with sprinkles is 1/30.

Find the midpoint of the line segment joining the two points.<br> (1.8, -3.4) and (-0.4, 1.4)
murzikaleks [220]

Answer:

(0.7, -1)

Step-by-step explanation:

To find the coordinates for the midpoint you add each coordinate together and divide by 2.

M = (\frac{1.8 - 0.4}{2},  \frac{-3.4 + 1.4}{2})

M = (\frac{1.4}{2}, \frac{-2}{2})

M = (0.7, -1)

Two cars leave the same location traveling in opposite directions. One car leaves at 3:00 p.m. traveling at an average rate of 5
Len [333]

x = hours

car 1 left an hour before car 2 so you have 55(x+1)

car 2 = 75x

 add them together to equal miles driven:

55(x+1) + 75x = 380

55x+55 + 75x = 380

 combine like terms:

130x+55 = 380

 subtract 55 from each side:

130x = 325

divide both sides by 130

x = 325 /130 = 2.5

x = 2.5 hours

 so 2.5 hours
