Answer: $ 400
Step-by-step explanation:
Amount collected for new library = $ 3,200 and there are 8 classes and they collected the same amount. This means that each class will collect
3200/ 8 = $400
We are given one angle that is 3 times less than others. Let us assume one angle measure is x degrees and another is 4x. Because x is 3x less than 4x. ( We can check 4x-x= 3x) Sum of complementary angles is 90 degrees. So, we can set up an equation, First angle measure + first angle = 90 degrees. x+4x = 90. Adding x and 4x, we get 5x. So, 5x = 90. Dividing both sides by 5, we get 5x/5 = 90. x= 18. So, one angle is 18 degrees. Another angle = 4x = 4 times 18 = 72 degrees. So, the required angles are of 18 degrees and 72 degrees.
Answer:
4
Step-by-step explanation:
A normally distributed result means that when the data is
plotted on a graph, we can actually see a bell shaped curve. That highest
frequency or peak is centered on the average value. Because it is shaped like
this, we can say that:
most scores are around the average with some scores being
lower or higher
This is combinations
exg. lets say you have 2 hats and 1 pair of shoes, the answe ris 2 options, if 2 hats and 2 pairs of shoes, the answer is 4 because 2 times 2=4
3 options for sandwitch
3 soup
4 salad
2 drink
we multiply all together
3 times 3 times 4 times 2=72 options
