Answer:
Lowest grade is 70.
Step-by-step explanation:
To have an average of 80 the total score is 4 * 80 = 320.
So the score for the next test must be 320 - (85 + 74 + 91)
= 70.
To solve this, take a look at the images provided and first find out the number of polygons out of the total number of cards given which would be 3 polygons out of 5 cards, which would be better represented as the fraction 3/5. Now, the question asks to find the probability of Julie picking a card that shows a polygon, and since 3 out of 5 of the cards are polygons, your answer would be 3/5.
Answer:
yes it can be scaline triangle
I’m pretty sure B because 1/4 divided by 1/2 equals 1/2 and that the only one that has a model that has 1/2 but don’t take my word for it
