A sports analyst determines that the number of points
scored in a basketball game is related to the number of
shots taken during the game. The least-squares
regression line is V = 5.0 + 1.2x, where y is the predicted
number of points scored and x is the number of shots
taken.
In one game, a team takes 50 shots and the residual is
10. How many points were scored by this team in this
game?

Step-by-step explanation:
The half-life of gold-195m is approximately 30.5 seconds.
Step 2 of 3: How much of a 12 gram sample of gold-195m would remain after 41 seconds? Round to three decimal places.
The amount of the 12 grams sample of gold-195m having a half-life of 30.5 s that would remain after 41 s is 4.726 g
How to determine the number of half-lives Half-life (t½) = 30.5 sTime (t) = 41 sNumber of half-lives (n) =?n = t / t½
n = 41 / 30.5
n = 82/61
How to determine the amount remaining Original amount (N₀) = 12 gNumber of half-lives (n) = 82/61Amount remaining (N) =?N = N₀ / 2ⁿ
N = 12 / 2^(82/61)
N = 4.726 g

Step-by-step explanation:
Assume a corporate bond pays a 5 percent coupon and matures in ten years. What will be the change in the current price of this bond if market interest rates increase from 5 to 5.5 percent?
The change in the current price of the bond when the market interest rates increase from 5% to 5.5% is a fall in the price of the bond.
What happens to bond prices with increased market interest rates?The attractiveness of bonds occurs when the interest rates fall. This fall drives up demand for bonds with fixed interest rates and the increasing demand causes bond prices to rise.
This implies that when interest rates rise, investors do not prefer the lower fixed interest rate paid by a bond. The reduced demand for bonds results in their declining prices.
Thus, when interest rates rise, bond prices fall and when interest rates fall, bond prices rise.

What is p(A)?
The probability model shows the distribution of people of age 20 to 39 years
The value of the probability P(A) is 0.631
How to determine the probability, P(A)From the question, the notation P(A) represents the probability that a person is either 20-24 years old or is married
From the table, we have the following parameters:
P(20-24) = 0.227 + 0.027 + 0.006 = 0.26P(Married) = 0.027 + 0.086 + 0.137 + 0.148 = 0.398P(20-24 and Married) = 0.027The probability, P(A) is then calculated as:
P(A) = P(20-24) + P(Married) - P(20-24 and Married)
Substitute known values
P(A) = 0.26 + 0.398 - 0.027
Evaluate the expression
P(A) = 0.631
Hence, the value of the probability P(A) is 0.631

4 flower bunches require 48 roses. how many bunches can be made with 84 roses?
Answer:
7 flower bunches
Step-by-step explanation:
One flower bunch requires 12 roses since 48/4 is 12
then to find out how many flower bunches can be made by 84 roses you would have to divide 84 by 12 which gives you 7.
Answer:
7
Step-by-step explanation:
48 roses divided by 4 roses is 12 roses per bunch.
84/12=7

The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
A graph titled Motion of a Dragonfly shows Time in hours on the x axis and Distance in miles on the y axis. The scale on the x axis shows number from 0 to 10 at increments of 2, and on the y axis, the numbers are shown from 0 to 330 at increments of 66. A straight line joins the ordered pairs 0, 0 and 2, 66 and 4, 132 and 6, 198
Based on the graph, what is the dependent variable, what is the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed?
The dependent variable is distance, the equation is y = 33x, and the dragonfly will travel 792 miles.
The dependent variable is distance, the equation is x = 33y, and the dragonfly will travel 1,056 miles.
The dependent variable is time, the equation is y = 33x, and the dragonfly will travel 792 miles.
The dependent variable is time, the equation is x = 33y, and the dragonfly will travel 1,056 miles.
Answer:
The dependent variable is distance, the equation is y = 33x, and the dragonfly will travel 792 miles
Step-by-step explanation:
ordered pairs: (0, 0) (2, 66) (4, 132) (6, 198)
slope of linear equation = change in y ÷ change in x
⇒ slope = (132 - 66) ÷ (4 - 2) = 33
Therefore, equation of the line: y = 33x
When x = 24, y = 33 × 24 = 792 miles
Distance is dependent on time, therefore distance is the dependent variable and time is the independent variable.

Incorrect answer:
8.3
Answer:
x + 2.6 = 10.4
x = 7.8
Step-by-step explanation:
If 2.6 liters are added to x liters with the result that 10.4 liters then exist, the model is ...
2.6 +x = 10.4 . . . . . . . 2.6 added to x gives 10.4
The commutative property of addition lets you rewrite this to ...
x +2.6 = 10.4

Subtracting 2.6 from both sides of the equation gives its solution:
x +2.6 -2.6 = 10.4 -2.6

Subtract six times the quantity 3a + 12b - 4c from eight times the sum of the quantities 14a +
70 and 5b - 12c
Answer:
94a - 32b - 72c + 560
Step-by-step explanation:
First get the product of 6(3a + 12b - 4c) = 18a + 72b - 24c.
Second get the sum of 14a + 70 and 5b - 12c = 14a + 5b - 12c + 70 then multiply by 8 and the product is 112a + 40b - 96c + 560. Subtract the first product from the 2nd product to get the final answer
