The school carnival committee sold a total of 200 tickets for the grand prize drawing. Sue bought enough tickets so that she had a 20 percent chance of winning the grand prize. How many tickets did Sue buy?
Answer:
40 tickets
Step-by-step explanation:
Given that:
Total tickets sold = 200
Sue's chances of winning = 20% = 0.2
Number of tickets bought by Sue :
P(winning) = 20%
P(winning) = required outcome / Total possible outcomes
Required outcome = number of tickets bought by Sue
Total possible outcomes = total number of tickets sold
0.2 = x / 200
x = 0.2 * 200
x = 40

2 hope that helps!!!! don´t forget to thank and BrainliestDoes (3,6) make the equation y = 2x true? ves
Answer:
Yes.
Step-by-step explanation:
In order to check if an equation is true, plug in the corresponding values for x and y.
Coordinates are written as (x, y). So, x = 3 and y = 6.
Plug in these values to the equation.
6 = 2 * 3
Multiply 2 and 3 to simplify:
6 = 6
This shows that the equation is true when given (3, 6)
Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years. Vince incorrectly calculates the amount he will pay back using the expression below. 900 + 900(1.015 • 2) What is the correct amount Vince will pay back altogether? Explain the error in Vince's expression. A. 00:00 $903; Vince should have subtracted the first 900 from the amount he will pay. B. 00:00 $913.50; Vince multiplied by the wrong number of years. C. 00:00 $927; Vince wrote the wrong number to represent the interest rate. D. 00:00 $1,813.50; Vince forgot to add the initial $900 to the amount he will pay.
Answer: C. 00:00 $927; Vince wrote the wrong number to represent the interest rate.
Step-by-step explanation:
Given that:
Amount borrowed (p) = 900
Simple interest (r) = 1.5% = 0.015
Time (t) = 2 years
Amount he'll pay back (A) :
A = P(1 + rt)
A = 900(1 + 0.015(2))
A = 900(1 + 0.03)
A = 900(1.03)
A = $927

What is the vertex of the quadratic function f(x)=x2+6x+16? Write your answer
as an ordered pair, (x,y).
Answer:
The vertex of the quadratic function is:
[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=x^2+6x+16[/tex]
As the vertex of the form [tex]y=ax^2+bx+c[/tex] is defined as:
[tex]x_v=-\frac{b}{2a}[/tex]
As the quadratic function of parabola params are
[tex]a=1,\:b=6,\:c=16[/tex]
so
[tex]x_v=-\frac{b}{2a}[/tex]
[tex]x_v=-\frac{6}{2\cdot \:1}[/tex]
[tex]x_v=-3[/tex]
Putting [tex]x_v=-3[/tex] to determine [tex]y_v[/tex]
[tex]y_v=\left(-3\right)^2+6\left(-3\right)+16[/tex]
[tex]y_v=3^2-18+16[/tex]
[tex]y_v=9-2[/tex]
[tex]y_v=7[/tex]
Therefore, the vertex of the quadratic function is:
[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]

A trade magazine routinely checks the drive-through service times of fast-food restaurants. Upper A 95% confidence interval that results from examining 771 customers in one fast-food chain's drive-through has a lower bound of 175.2 seconds and an upper bound of 178.2 seconds. What does this mean?
Answer:
Step-by-step explanation:
The confidence interval is an interval that determines an unknown population parameter. It showcases the probability that a particular population parameter will fall within this interval. As the sample size reduces, the width of the confidence interval usually increases.
What the given question mean is that one can still be 95% confident that the mean drive-through service times of this fast-food chain is between 175.2 seconds and 178.2 seconds.

Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6 pounds of ground turkey? Complete the explanation. When entering the equation, use y to represent how many servings he can make and x to represent how many pounds of ground turkey he has.
Answer:
12 servings
Step-by-step explanation:
Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6 pounds of ground turkey?
From above question:
2.5 pounds of ground turkey = 5 servings
6 pounds of ground turkey = x
Cross Multiply
2.5 × x = 6 × 5
x = 6 × 5/2.5
x = 12 servings
Hence, 6 pounds of ground turkey can make 12 servings.
Completing the explanation.
The equation is
5x = 2.5y
where:
x = represent how many pounds of ground turkey he has = 6 pounds
y = to represent how many servings he can make
Hence,
5 × 6 = 2.5y
y = 5 × 6/2.5
y = 12 servings

HELPPPPP!! A juggler tosses a ball into the air. The ball leaves the juggler's hand 5 feet above the ground and has an initial velocity of 30 feet per second. The juggler catches the ball when it falls back to a height of 2 feet. How long is the ball in the air? Use the model h(t)=−16t2 +v0t +h0, where v0 is the initial velocity (in feet per second), h is the height (in feet), t is the time in motion (in seconds) and h0 is the initial height (in feet).
Remember to round your answer to the nearest hundredth.
Answer:
t = 2.525 seconds
Step-by-step explanation:
h(t) = -16t^2 + v*t + h0 h(t) = the height above the ground after t seconds v = 40 ft/s initial velocity h0 = 4 ft the initial height of the object (the ball) t = the time of the motion h(t) = -16t^2 + 40*t + 4 we need to find t such that h(t) = 3 ft 3 = -16t^2 + 40*t + 4 -16t^2 + 40*t + 4 = 3 by solving we find
t = 2.525 seconds
You can round on your own.
Solving the quadratic equation, it is found that the ball was in the air for 1.97 seconds.
The height of the ball, in feet, after t seconds is given by:
[tex]h(t) = -16t^2 + v(0)t + h(0)[/tex]
In this problem:
The initial velocity is [tex]v(0) = 30[/tex].The initial height is [tex]h(0) = 5[/tex].Thus, the equation is:
[tex]h(t) = -16t^2 + 30t + 5[/tex]
The juggler catches the ball when it falls back to a height of 2 feet, thus it stays in the air until t for which:
[tex]h(t) = 2[/tex]
Then:
[tex]2 = -16t^2 + 30t + 5[/tex]
[tex]-16t^2 + 30t + 3 = 0[/tex]
[tex]16t^2 - 30t - 3 = 0[/tex]
Which is a quadratic equation with coefficients [tex]a = 16, b = -30,c = -3[/tex]. Then:
[tex]\Delta = b^2 - 4ac = (-30)^2 - 4(16)(-3) = 1092[/tex]
[tex]x_{1} = \frac{30 + \sqrt{1092}}{2(16)} = 1.97[/tex]
[tex]x_{2} = \frac{30 - \sqrt{1092}}{2(16)} = -0.1[/tex]
The ball stays in the air for 1.97 seconds.

The triangles are similar. Find
the missing side length x.
Answer:
x = 66
Step-by-step explanation:
The similarity ratio is DO/PA = 27/18 ➡3/2
So DT/PN ➡ x/44 = 3/2
132 = 2x divide both sides by 2
x = 66
The point A (−5,4) is reflected over the point (−2,5) and its image is point B. What are the coordinates of point B?
Answer:
The coordinates of B are (1,6)
Step-by-step explanation:
Point Reflection
Given the point P(x,y) and its reflection P'(x',y') with respect to the point C(xc,yc), C is the midpoint of the segment PP'.
This means the coordinates of C are:
[tex]\displaystyle x_c=\frac{x+x'}{2}[/tex]
[tex]\displaystyle y_c=\frac{y+y'}{2}[/tex]
If the coordinates of the midpoint are given, then the endpoint P' can be found solving for x' and y':
[tex]x'=2x_c-x[/tex]
[tex]y'=2y_c-y[/tex]
The point P' is the reflection of P over C.
We are given the coordinates of A(-5,4) and the point (-2,5). We need to find the coordinates of point B(x',y'). Let's use the formulas as if A was point P and C=(-2,5):
[tex]x'=2(-2)-(-5)=-4+5=1[/tex]
[tex]y'=2(5)-4=10-4=6[/tex]
The coordinates of B are (1,6)
