Answer:
The fraction of the rebounds the rest of the team get was 13/72 (13 out of the 72 total)
Step-by-step explanation:
Jacob gets 4/9
Adam gets 3/8
Since the given fraction provided doesn't have common denominator we would need to do thos first...
4/9 x 8/8 = 32/72
3/8 x 9/9 = 27/72
combining Adam and Jacob rebounds...
32/72 + 27/72 = 59/72
so the remaining, uncounted rebounds are...
72 - 59 = 13

if a rhombus has an area of 264 square units. If DB=12 units, find AC
Using the formula for calculating the area of a rhombus, the length of /AC/ is 44 units
Calculating the area of a RhombusFrom the question, we are to determine the length of AC
The area of a rhombus is given by
[tex]A = \frac{pq}{2}[/tex]
Where A is the area
p and q are the diagonals
Then, for the given diagram,
[tex]A = \frac{/DB/ \times /AC/}{2}[/tex]
From the given information,
A = 264 square units
/DB/ = 12 units
∴ [tex]264 = \frac{12\times /AC/}{2}[/tex]
[tex]264 = 6\times /AC/[/tex]
[tex]/AC/ = \frac{264}{6}[/tex]
/AC/ = 44 units
Hence, the length of /AC/ is 44 units

NO LINKS!!! Exponential Growth and Decay Part 1
Problem 1
a = 2500 = starting amount
b = 1 + r = 1 + 0.035 = 1.035 = growth factor
The equation is [tex]y = 2500*1.035^x[/tex] as it is in the form [tex]y = a*b^x[/tex]
Plug in y = 5000 and solve for x.
[tex]y = 2500*1.035^x\\\\5000 = 2500*1.035^x\\\\1.035^x = 5000/2500\\\\1.035^x = 2\\\\\log(1.035^x) = \log(2)\\\\x\log(1.035) = \log(2)\\\\x = \log(2)/\log(1.035)\\\\x \approx 20.148792\\\\x \approx 21\\\\[/tex]
I rounded up to get over the hurdle. This is because plugging x = 20 will lead to y being smaller than $5000, so we must use x = 21.

The equation goes from [tex]y = a*b^x[/tex] to [tex]y = 4.22*1.031^x[/tex]
Plug in y = 9.33 and solve for x.
[tex]y = 4.22*1.031^x\\\\9.33 = 4.22*1.031^x\\\\1.031^x = 9.33/4.22\\\\1.031^x \approx 2.21090047393365\\\\\log(1.031^x) \approx \log(2.21090047393365)\\\\x\log(1.031) \approx \log(2.21090047393365)\\\\x \approx \log(2.21090047393365)/\log(1.031)\\\\x \approx 25.9882262216245\\\\x \approx 26\\\\[/tex]

Problem 3
a = 400 = initial value
b = 1 + r = 1 + 0.25 = 1.25 = growth factor
The template [tex]y = a*b^x[/tex] updates to [tex]y = 400*1.25^x[/tex]
Plug in y = 3000 and isolate x.
[tex]y = 400*1.25^x\\\\3000 = 400*1.25^x\\\\1.25^x = 3000/400\\\\1.25^x = 7.5\\\\\log(1.25^x) = \log(7.5)\\\\x\log(1.25) = \log(7.5)\\\\x = \log(7.5)/\log(1.25)\\\\x \approx 9.029627\\\\x \approx 10\\\\[/tex]
Like with the first problem, I rounded up to the nearest whole number. If you tried out x = 9, then y = 2980 approximately which is short of the goal of 3000. Trying x = 10 leads to y = 3725 approximately, which is now over the goal we're after.

a local pizzaria offers 15 toppings for their pizzas you can choose any 4 of them for a fixed price how many different types of pizzas can you order with 4 toppings
Since we can choose 4 of the 15 toppings, we can order 1365 different types of pizzas with 4 toppings
Since the question says 'choose', it is a combination question and order is not important.
What is combination?This is the number of ways in which x objects can be selected from n objects.
It is given mathematically as ⁿCₓ = n!/[r!(n - r)!]
Number of different types of pizzasNow given that we have 15 toppings for pizza and we want to choose any 4, So, we are choosing 15 toppings in 4 ways. So,
n = 15 and r = 4So, ¹⁵C₄ = 15!/4!(15 - 4)!
= 15!/4!11!
= 15 × 14 × 13 × 12 × 11!/4!11!
= 15 × 14 × 13 × 12/24
= 15 × 7 × 13
= 1365 ways

Answer:
[tex]\boxed{\sf distance \: between \: the \: objects \: \: is \: 2.5 \: cm}[/tex]
Step-by-step explanation:
According to universal law of gravitation every object in the universe attracts every other particles that surrounds it with a force which is inversely proportional to the square of their distance of separation & directly proportional to
the product of their masses, given by standard formula.
[tex]A = G \cdot \frac{m_1.m_2}{ {d}^{2} } [/tex]
where A,d & G are force of attraction, distance of separation & proportionality constant respectively.
Given:
A1 = 2 units
d1= 5 cm
A2 = 8 units
To find:
Distance of separation when the force of attraction is 8 units d2 = ?
Solution:
Substituting the given values in above at each point,
[tex]A_1 = G \cdot \frac{m_1.m_2}{ {d_1}^{2} } \\ 2 = G \cdot \frac{m_1.m_2}{ {5}^{2} } \\ \sf similarly \: at \: second \: point \: of \: attraction \\ A_2 = G \cdot \frac{m_1.m_2}{ {d_2}^{2} } \\ 8 = G \cdot \frac{m_1.m_2}{ {d_2}^{2} } \\ \sf \: \: dividing \: both \: of \: the \: equation \\ \frac{2}{8} = \frac{G \cdot \frac{m_1.m_2}{ {5}^{2} }}{G \cdot \frac{m_1.m_2}{ {d_2}^{2} } } \\ \sf \: G \: m_1 and \: m_2 \: are \: \: constant \: hence \\ \sf they \: can \: be \: cancelled \: out \\ \frac{2}{8} = \frac{ \frac{1}{ {5}^{2} } }{ \frac{1}{ {d_2}^{2} } } \\ \sf rearranging \: above \: equation \\ \frac{1}{4} = \frac{{d_2}^{2} }{ {5}^{2} } \\ {d_2}^{2} = \frac{ {5}^{2} }{4 } \\ {d_2}^{2} = \frac{25}{4} \\ {d_2}^{2} = 6.25 \\ \sqrt{{d_2}^{2} } = \sqrt{6.25} \\ \boxed{ \sf{d_2} = 2.5 \: cm}[/tex]

32 - 4= 28.28 is your answer.A company is started by four friends. The company was Erica’s idea, so she wants to fill 70% of the orders. Jen, Heather, and Tonya each agree to fill 10% of the orders. After a successful first year, Erica wants to determine if the distribution of the number of orders filled is adhering to the agreed-upon percentages. She decides to test:
To do so, she selects a random sample of 100 orders from the large number of orders that were filled and determines who filled the order. She finds that Erica filled 56 orders, Jen filled 18, Heather filled 14, and Tonya filled 12. The chi-square test statistic for goodness of fit is χ2 = 11.20 and the P-value is between 0.01 and 0.02.
Because the P-value is less than 0.05, Erica rejects the null hypothesis. Because the null hypothesis is rejected, she would like to know which term contributed the significance of the test. Complete a follow-up analysis. Which term contributed the most to the significance of this test? Were there more or fewer orders being filled by this person than expected?
Erica, more than expected
Erica, fewer than expected
Jen, more than expected
Jen, fewer than expected
The appropriate hypotheses for this test are
Erica filled 70
Jen filled 10
Heather filled 10
Tonya filled 10
A company is started by four friends.
The company was Erica’s idea,
So she wants to fill 70% of the orders. Jen, Heather, and Tonya each agree to fill 10% of the orders.
What is the meaning of the hypothesis?A hypothesis is a statement that proposes a result that will be tested to get a verified result.
A hypothesis is not hundred percent true, that is why it is always put to test.
The hypothesis is singular while the hypothesis is plural.
Making a hypothesis in this case is an attempt to predict an answer or result that will be verified by doing the experiment.
We can conclude by saying that a hypothesis is not hundred percent true.

When Josiah buys a ticket at the local movie theater, he receives 100 reward points to use toward future purchases. He is offered a scratch-off card instead of the points, which will allow him to try for a higher point value. The three possible point awards on the scratch-off card are 25, 100, and 120. There is an equal number of cards for each point award in the stack he chooses the card from.
Which statement is true?
A
The best option is to take the 100 points because the expected value of the points from the scratch-off card is less than 100 points.
B
The best option is to take the scratch-off card because two of the three possible point values on the card are the same or greater than the 100 points.
C
The best option is to take the scratch-off card because the 120-point value that is on the card is greater than 100 points.
D
The best option is to take the 100 points because the probability of being awarded more than 100 points on the scratch-off card is zero.
The best option is to take the 100 points because the expected value of the points from the scratch-off card is less than 100 points option (A) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Since, there is an equal number of cards of point 25, 100, and 120
P(x =25) = P(x =100) = P(x =200) = 1/3
x: 25 100 120
P(x): 1/3 1/3 1/3
The expected value is:
E(x) = 25×(1/3) + 100×(1/3) + 125×(1/3)
E(x) = 245/3 < 300/3 = 100
Thus, the best option is to take the 100 points because the expected value of the points from the scratch-off card is less than 100 points option (A) is correct.
