17. See below
18. 750
Step-by-step explanation:
17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.
18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:
[tex]y=0.5x+125[/tex]
Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:
[tex]500=0.5x+125[/tex]
[tex]500-125=0.5x[/tex]
[tex]375=0.5x[/tex]
[tex]\frac{375}{0.5} =x[/tex]
[tex]375*2=x[/tex]
[tex]750=x[/tex]
Thus, 750 lollipops must be sold.

Answer: 358,002,479
Step-by-step explanation:
First, you have 358 million, or 358,000,000.
Next, you have 2,000. You can add that to 358,000,000 and you get 358,002,000.
Finally, you have 479. You can add that to 358,002,000, and get 358,002,479.

Step-by-step explanation:
Given
4 - [tex]\frac{6}{9}[/tex] = [tex]\frac{1}{3}[/tex] + x ( multiply through by 9 to clear the fractions )
36 - 6 = 3 + 9x
30 = 3 + 9x ( subtract 3 from both sides )

3 = x
A trade magazine routinely checks the drive-through service times of fast-food restaurants. Upper AA 9595% confidence interval that results from examining 773773 customers in one fast-food chain's drive-through has a lower bound of 169.0169.0 seconds and an upper bound of 172.2172.2 seconds. What does this mean?
Answers
Answer:
One can be 95% confident that the drive-through service times of fast-food chain is between 169 seconds and 172 seconds.
Step-by-step explanation:
The confidence interval gives a range of value for the population mean or parameter, which is calculated from the statistic value of the data (that is sample statistic). This range gives the interval which is associated with a certain level of confidence for which the interval will contain the true value of the unknown parameter (true value). In the scenario above, the associated confidence level is 95%.Hence, we can be 95% confident that the true value will be continued with the interval (169 ; 172)

You throw a ball at a height of 5 feet above the ground. The height h (in feet)
of the ball after t seconds can be modeled by the equation h=-16tsqaured +44t +5
A. After how many seconds does the ball reach a height of 15 feet?
B. After how many seconds does the ball hit the ground? Round your answer
to two decimal places.
Answers
Answer:
A. After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. 2.86 sec is the time it takes to hit the ground
Step-by-step explanation:
A. let h = 15
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = .25
After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t. (I will let you do that)
t = 2.85929... or t = -.10929...
t cannot be negative, so 2.86 sec is the time it takes to hit the ground
The answer of A is After 2.5 sec and 0.25 sec the ball was at a height of 15 ft and the answer of B is 2.86 sec is the time it takes to hit the ground.
A. let h = 15
What is the quadratic equation?
[tex]ax^2+bx+c=0[/tex]
a, b, c=known numbers, where a ≠ 0
x=the unknown
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = 0.25
After 2.5 sec and 0.25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t.
t = 2.85929... or t = -.10929...
t cannot be negative, So 2.86 sec is the time it takes to hit the ground.

B: More than half of the scores were 90% or greater.
C: There were no scores less than 85%
D: There were no scores less than 90%
E: At least one score was exactly 85%
F: At least one score was exactly 90%
Answers
Answer:
A: More than half of the scores were 85% or greater.
E: At least one score was exactly 85%
Step-by-step explanation:
Here the 5 test would be taken in science so 85% would be the result of one of the test
Also 85% represent the median so it means there are 2 values more and 2 values less
So there are 3 results with 85% or greater
Hence, the option A and Option E is correc

Step-by-step explanation:
right triangles: c^2 = a^2 + b^2
c is the largest side
for A: c = 5, a = 3, b = 4
5^2 = 3^2 + 4^2
25 = 25, so A is a right triangle
for B, c = 13, a = 5, b = 12
13^2 = 5^2 + 12^2
169 = 169, so B is a right triangle
for C, c = 4, a = 2, b = 3
4^2 = 2^2 + 3^2
16 ≠ 13, so C is not a right triangle
So, A and B are right triangles.
