Pythagorean Theorem: How many yards will the players have to run?
Answer:
≈ 125.3
Step-by-step explanation:
If we're using the Pythagorean Theorem to solve this, then the formula is:
[tex]a^{2}+ b^{2} =c^{2}[/tex]
So basically, by using this formula, you're finding the length that the soccer players will run diagonally. Plug in the numbers:
[tex]110^2 + 60^2 = c^2[/tex]
12100 + 3600 = [tex]c^2[/tex]
15700 = [tex]c^2[/tex]
Take the square root:
15700 = [tex]c^2[/tex]
[tex]\sqrt{15700} = \sqrt{c^2}[/tex]
125.3 ≈ c

The table shows the number of mobile cellular subscriptions per 100 people in Australia for different years.
Year | Cellular subscriptions / 100 people
1993 | 4 12 25 33 57 72 90 101 101 108
1995 | 12
1997 | 25
1999 | 33

The quadratic regression equation using the years since 1990 for the input variable and the number of cellular subscriptions for the output variable is y=−0.107x^2+9.008x−28.851
What is the predicted number of cellular subscriptions per 100 people in Australia in 2030?
Round your answer to the nearest whole number. Enter your answer in the box.
Nvm its 160
Answer:
160
Step-by-step explanation:
x represents the years since 1990, so at 2030, x = 2030 - 1990 = 40. Replacing this value into the quadratic regression equation, we get:
y = -0.107(40)^2 + 9.008(40) - 28.851 = 160
which is the predicted number of cellular subscriptions per 100 people in Australia in 2030

1. Jayden spent $46.20 on 12 gallons of gasoline. What was the price per gallon?
2. Jayla buys 1.2 pounds of bananas. The bananas cost $1.29 per pound. To the nearest cent, how much does Jayla pay for the bananas?
3.Billy ate 1/4 of a pizza, and Wi ate 1/3 of the same pizza. How much of the Pizza did they eat in all?
plz show the work
Answer: 1. $3.85
2. $1.55
3. 7/12
Step-by-step explanation:
1. Since you are finding out price PER gallon, you would divide $46.20 by 12 because Jayden bought 12 gallons.
2. Since they give you the price per gallon and the amount bought in this problem, you will multiply 1.2 and $1.29. Think of this as if you were buying 5 apples and each cost $1, you would do 5 x 1 to find the total cost. The same concept applies here.
3. To add 1/4 and 1/3 you would find a common denominator. The common denominator would be 12. 1/4 = 3/12 and 1/3 = 4/12. Now you can add them together, 3/12 + 4/12 = 7/12
What are the points of discontinuity?
Answer:
x = 9, x = 3
Step-by-step explanation:
Given
y = [tex]\frac{x-3}{x^2-12x+27}[/tex]
The denominator of the rational function cannot be zero as this would make y undefined.
Equating the denominator to zero and solving gives the values that x cannot be, that is
x² - 12x + 27 = 0
(x - 9)(x - 3) = 0
Equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x - 3 = 0 ⇒ x = 3
Thus x = 9, x = 3 are excluded values and the points of discontinuity

Sabrina has a rug with a perimeter of 18 feet. She decides to place a border around the rug so that the new length of the rug is 8 feet and the width is 4 feet. The border is the same width all the way around. A rectangle has a length of 8 feet and width of 4 feet. The equation which represents x, the width of the border is 2 (8 minus 2 x) + 2 (4 minus 2 x) = 18. What is the width of the border? Three-fourths ft 1 and one-half ft 1 ft 3 ft
Answer:
3/4 ft.
Step-by-step explanation:
2(8-2x)+2(4-2x)=18
16-4x+8-4x=18
-8x=18-24
-8x=-6
x=-6/-8
x= 3/4
The width of the border is 3/4.
What is perimeter of rectangle?The perimeter of rectangle is, P= 2(l + b).
Given:
length= 8 feet, width = 4 feet
2(8-2x)+2(4-2x)=18
16-4x+8-4x=18
-8x=18-24
-8x=-6
x=-6/-8
x= 3/4
Hence, the width of the border is 3/4.

Miguel has to take two quizzes tomorrow. He has only enough time to study
for one of them.
• The history quiz has 4 true-or-false questions.
• The science quiz has 3 multiple-choice questions.
Miguel calculates the probability that he will get all the questions correct by
guessing.
To get 100% correct:
P(guess is correct)
History
Answer 4 of 4 correctly.
0.5
Science
Answer 3 of 3 correctly.
0.2
Miguel will study for the quiz on which he is likely to do worse by guessing.
Which quiz should he study for?
O
A. History, because he must get more questions correct.
B. Science,
C.History,
Answer:
Option B is correct.
Miguel should study for the Science quiz as he will do worse in that quiz by guessing.
Step-by-step explanation:
Miguel has to take two quizzes
1) 4 true or false questions on History with a 0.5 chance of acing the quiz
Expected number of correct questions = np
n = number of questions
p = probability of acing the test
Expected number of correct questions = 4 × 0.5 = 2
2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.
Expected number of correct questions = 0.2 × 3 = 0.6
It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.

What is the value of x?
Answer:
5 sqrt(3)
Step-by-step explanation:
Since this is a right triangle
sin theta = opposite side/ hypotenuse
sin 60 = x /10
10 sin 60 = x
10 sqrt(3) /2 =x
5 sqrt(3) =x
Answer:
5√3
Step-by-step explanation:
The sine function ties together the information at hypotenuse = 10, opposite side = x and angle of elevation = 60 degrees:
sin 60 degrees = opp side / hypotenuse = x/10.
Therefore, x = 10 sin 60 degrees = √3/2, and so x = 10√3/2 = 5√3 (equal to the third answer choice).
A plant can manufacture 100 golf clubs per day for a total daily cost of $7,800 and 120 golf clubs per day for a total daily cost of $8,400. Assuming that the daily cost and production are linearly related, find the number of golf clubs manufactured if the total daily cost is $12,300. * A. 167 B. 250 C. 410 D. 4,800
Answer:
The correct option is (B) 250.
Step-by-step explanation:
A plant can manufacture 100 golf clubs per day for a total daily cost of $7,800.
And 120 golf clubs per day for a total daily cost of $8,400.
Let X = number of golf clubs manufactured per day.
Let Y = total cost of manufacturing golf clubs per day
It is provided that:
(x₁, y₁) = (100, 7800)
(x₂, y₂) = (120, 8400)
Form the least square regression line using two-point form as follows:
[tex](y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\ (x-x_{1})[/tex]
[tex](y-7800)=\frac{8400-7800}{120-100}\ (x-100)\\\\(y-7800)=30\times (x-100)\\\\y-7800=30x-3000\\\\y=30x+4800[/tex]
The least square regression line to estimate the total daily cost of x golf clubs manufactured daily is:
y = 30 x + 4800
Compute the number of golf clubs manufactured if the total daily cost is $12,300 as follows:
[tex]y = 30 x + 4800\\12300=30x+4800\\30x=7500\\x=250[/tex]
Thus, the correct option is (B).

The surface area of the rectangular pyramid is the sum of the whole areas.
The total surface area is the sum of the whole area.
A rectangular pyramid has 4 triangular faces and a rectangular base.
Therefore,
total surface area = 7.8 cm² + 7.8 cm² + 16.5 cm² + 16.5 cm² + 60 cm²
total surface area = 108.6 cm²

What is the probability of rolling a die 6 times and getting the numbers 1, 2, 3, 4, 5, 6 in that order? Select the best answer from the choices provided.
A. 0.001389
B. 0.000129
C. 0.000021
D. 0.0000038
Answer:
C. 0.000021
Step-by-step explanation:
Each roll of the die is an independent event.
The probability of rolling a 1, then a 2, then a 3, then a 4, then a 5, then a 6 is the product of the 6 individual probabilities.
Probability of rolling a 1:
There are 6 possible outcomes, rolling 1, 2, 3, 4, 5, or 6.
There is one desired outcome, rolling a 1.
p(1) = 1/6
Probability of rolling a 2:
Similar to rolling a 1, there is 1 desired outcome,rolling a 2, out of 6 possible outcomes.
p(2) = 1/6
The same is true for rolling a 3, 4, 5, or 6. Each one has a probability of 1/6.
p(1, 2, 3, 4, 5, 6, in that order) = p(1) * p(2) * p(3) * p(4) * p(5) * p(6)
= (1/6)^6
