temperatures on bacteria. She cools one sample of bacteria to a temperature of
-51°C and another.to -76°C. What was the temperature difference in the two

A candy distributor needs to mix a 10% fat-content chocolate with a 60% fat-content chocolate to create
100 kilograms of a 25% fat-content chocolate. How many kilograms of each kind of chocolate must they
use?
Answer: They must mix
Kilograms of the 10% chocolate and
Kilograms of the 60% chocolate.

Answers

Answer:

They must mix 70 kilograms of the 10% chocolate and 30 kilograms of the 60% chocolate.

Step-by-step explanation:

Given that a candy distributor needs to mix a 10% fat-content chocolate with a 60% fat-content chocolate to create 100 kilograms of a 25% fat-content chocolate, to determine how many kilograms of each kind of chocolate must they use, the following calculations must be performed:

10 x 0.5 + 60 x 0.5 = 35

10 x 0.6 + 60 x 0.4 = 30

10 x 0.7 + 60 x 0.3 = 25

100 x 0.7 = 70

Thus, they must mix 70 kilograms of the 10% chocolate and 30 kilograms of the 60% chocolate.

left 2 units, horizontal stretch by a factor of 2, down 9 units

left 2 units, down 9 units, vertical compression by a factor of 0.5

left 2 units, down 9 units, horizontal stretch by a factor of 2

Answers

Answer:

C) left 2 units, down 9 units, vertical compression by a factor of 0.5.

Step-by-step explanation:

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis and if there is a vertical stretch.

Parent Function:  

g ( x ) = x 2

Horizontal Shift: Left  2  Units

Down: 9 Units

Vertical Shift: Down  0.5  Units

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: Compressed

A game has 28 white balls and 12 red balls in a bag, and you will randomly select one ball from the bag. If
the selected ball is white, you lose $5. And, if the ball is red, you win $10. What is the expected value of
the game?

Answers

Answer:

There are 40 balls in the bag. The probability of selecting a white ball is 28/40, simplified to 7/10. The probability of selecting a red ball is 12/40, simplified to 3/10. You are more likely to get a white ball so you will most likely lose $5.
