Coach De Leon purchases sports equipment. Basketballs cost $20.00 each, and soccer balls cost $18.00 each. He had a budget of $150.00.
Answers
Answer:
18s+20b<_150
Step-by-step explanation:
He can buy 5 basketballs and 2 soccer balls. This equation is correct because 18x2 is 36 and 20x5 is 100. So that will be a total of $100. This makes the equation 100<_150. You can infer that this equation is true.
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.
Answers
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

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?
Answers
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.

Have a great day y'all :)
(–4 + i) + 4i = –4 + (i + 4i) is the associative property of addition. Thus, option A is correct.
What is the associative property of addition?According to the associative property of additionally, whenever at least three figures are added together, the outcome is unaffected by the sequence in which the individual numbers are added.
In the first given condition is is stated:
(–4 + i) + 4i = –4 + (i + 4i)
-4 + i + 4i = -4 + i + 4i
5i - 4 = 5i - 4
As the LHS = RHS, the property is said to be valid for the associative property of addition.
Therefore, option A is the correct option.

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?
Answers
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
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.
Answers
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.
