Answer:
The expected number of pizza servings is 270.
Step-by-step explanation:
Food Item Preferred Number of Students
pizza 27
cheeseburger 14
salad bar 9
Now we have been given that Fifty students were randomly selected to take part in a survey about their favorite school lunch. The school will be serving 500 lunches;
This means 10% of the total lunches or students were selected. So, if 27 students prefer pizza this means its 10 times will be needed for the whole lot making it pizzas.
Similarly, 140 cheeseburgers and 90 salad bars will be served making a tital of = lunches.
Answer:
4.5, -27, 162,-972, 5832
Step-by-step explanation:
The given recursive definition is,
This will form a geometric sequence with first term 4.5 and common ratio r=-6.
When n=2, we have:
When n=3, we get:
When n=4, we get:
When n=5, we get:
Therefore the first five terms are:
4.5, -27, 162,-972, 5832
Answer:
A. 31/100
Step-by-step explanation:
Change 3/10 to hundreds:
3/10 × 10/10 = 30/100
The denominator (the bottom number) must be 100.
61 - 30 is 31.
The missing number is 31/100. See image.
