The number of two-points and three points shot The Cruisers scored are 24 and 19 points respectively.
How to find the number of two and three points made?The Cruisers scored a total of 105 points in a basketball game. They also had a total of 43 baskets, of which some were two-point shots and some of were three-point shots.
Therefore, the number of two-points and three-points the cruiser scored is as follows:
x = number of two-points
y = number of three-points
So;
x + y = 43 -------1
Also;
2x + 3y = 105 -----2
Multiplying equation(1) by 2
2x + 2y = 86
2x + 3y = 105
Subtract equation(i) from equation(ii)
y = 19
To find x:
x = 43 - 19
x = 24
Therefore,
number of two-points = 24
number of three-points = 19

Let L{x(t)} = U(s) & Lfy(t)} = V(s).
Evaluate: U(2)
Round-off answer to 2 decimal places.... Show more
To find U(2), we need to solve the given system of equations using Laplace transforms, find the inverse Laplace transforms of X(s) and Y(s) to obtain x(t) and y(t), respectively, and then substitute t=2 into x(t).
To solve the given system of equations, we will use Laplace transforms. First, let's find the Laplace transforms of the given equations:
1) Taking the Laplace transform of the first equation, we get:
s^2X(s) - s + 5Y(s) = 1/s^2
2) Taking the Laplace transform of the second equation, we get:
s^2Y(s) - 4Y(s) - 2sX(0) = -2/s
Using the initial conditions, we can simplify the second equation:
s^2Y(s) - 4Y(s) = -2/s
Now, let's solve the above equations for X(s) and Y(s). Rearranging the first equation, we have:
X(s) = (1 + s - 5Y(s)) / s^2
Substituting this into the second equation, we get:
s^2Y(s) - 4Y(s) = -2/s + 2(1 + s - 5Y(s)) / s^3
Simplifying, we have:
s^3Y(s) - 4sY(s) = -2 + 2/s + 2s - 10Y(s)
Combining like terms, we obtain:
s^3Y(s) - 10Y(s) - 4sY(s) + 10Y(s) = -2 + 2/s + 2s
Simplifying further, we get:
s^3Y(s) - 4sY(s) = -2 + 2/s + 2s
Now, we can solve for Y(s):
Y(s)(s^3 - 4s - 10) = -2 + 2/s + 2s
Finally, we can find the inverse Laplace transform of Y(s) to obtain y(t). From the equation above, we see that Y(s) is a function of s, which means we can use partial fraction decomposition to simplify it. Once we find Y(s), we can find x(t) using the equation x(t) = L^(-1)[X(s)]. Once we have x(t) and y(t), we can evaluate U(2) by substituting t=2 into x(t).
In conclusion, to find U(2), we need to solve the given system of equations using Laplace transforms, find the inverse Laplace transforms of X(s) and Y(s) to obtain x(t) and y(t), respectively, and then substitute t=2 into x(t).

How many places does the decimal point move when you divide a number by 10? In which direction?
If we divide an 8 by 10 for example, the answer is 0.8, So, when you divide a number by 10, you should move 1 place the decimal point to the left direction.
For example:
\(\begin{gathered} \frac{0.5}{10}=0.005 \\ \frac{78.0}{10}=7.8 \\ \frac{34.5}{10}=3.45 \end{gathered}\)andrea and lauren are 20 kilometers apart. they bike toward one another with andrea traveling three times as fast as lauren, and the distance between them decreasing at a rate of 1 kilometer per minute. after 5 minutes, andrea stops biking because of a flat tire and waits for lauren. after how many minutes from the time they started to bike does lauren reach andrea? (a) 20 (b) 30 (c) 55 (d) 65 (e) 80
The correct answer is option (C) 55 minutes.
Let's break down the information given in the problem:
Distance between Andrea and Lauren at the start: 20 kilometersRate at which the distance between them is decreasing: 1 kilometer per minuteAfter 5 minutes, Andrea stops biking and waits for LaurenTo find out how long it takes for Lauren to reach Andrea, we need to determine the time it takes for Andrea to cover half the distance between them. Once Andrea reaches the halfway point, Lauren will also have traveled the same distance.
Let's denote the time it takes for Andrea to reach the halfway point as "t" minutes. Since the distance decreases at a rate of 1 kilometer per minute, after "t" minutes, the distance between Andrea and Lauren will be reduced by "t" kilometers.
Now, let's calculate the distance traveled by Andrea in "t" minutes:
Distance = Rate × Time
Since Andrea is traveling three times as fast as Lauren, her rate is 3 times the rate of Lauren.
Distance traveled by Andrea in "t" minutes = (3 × 1) × t = 3t kilometers
The total distance between Andrea and Lauren at that time will be:
Distance between Andrea and Lauren = 20 - t kilometers
Since they meet at the halfway point, the distance traveled by Andrea (3t) will be equal to half the total distance (20 - t)/2:
3t = (20 - t)/2
To solve this equation, we can multiply both sides by 2:
6t = 20 - t
Now, solve for "t":
6t + t = 20
7t = 20
t = 20/7
Therefore, it will take Andrea 20/7 minutes to reach the halfway point.
Since Lauren continues biking for 5 more minutes after Andrea stops, the total time it takes for Lauren to reach Andrea is:
Total time = t + 5 = 20/7 + 5
To calculate this, we can convert 5 minutes to a fraction with a denominator of 7:
5 minutes = 35/7 minutes
Total time = 20/7 + 35/7 = (20 + 35)/7 = 55/7
So, Lauren will reach Andrea after 55/7 minutes.
To find the answer option that matches this time, we can calculate 55/7 and compare it to the answer choices:
55/7 ≈ 7.86
Among the given answer choices, the closest option to 7.86 is (C) 55. Therefore, the answer is (C) 55 minutes.

Find the measure of
=======================================================
Explanation:
The angles SPT and TPU marked in red are congruent. They are congruent because of the similar arc markings.
Those angles add to the other angles to form a full 360 degree circle.
Let x be the measure of angle SPT and angle TPU.
86 + 154 + 60 + x + x = 360
300 + 2x = 360
2x = 360-300
2x = 60
x = 60/2
x = 30
Each red angle is 30 degrees.
Then,
angle SPQ = (angle SPT) + (angle TPU) + (angle UPQ)
angle SPQ = (30) + (30) + (86)
angle SPQ = 146 degrees
--------------
Another approach:
Notice that angles QPR and RPS add to 154+60 = 214 degrees, which is the piece just next to angle SPQ. Subtract from 360 to get:
360 - 214 = 146 degrees

to run a test for which the alternative hypothesis is Hj: p1 > p2- Find the appropriate test statistic for the
test. Enter the test statistic - round to 4 decimal places. Z =
The appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).
To find the appropriate test statistic for a 2-sample z-test for two proportions, we need to calculate the standard error and then use it to compute the z-score. The formula for the standard error is:
SE = sqrt[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]
Where p1 and p2 are the sample proportions, and n1 and n2 are the sample sizes.
In this case, we have the following values:
X1 = 24 (number of successes in sample 1)
n1 = 200 (sample size 1)
X2 = 17 (number of successes in sample 2)
n2 = 150 (sample size 2)
To calculate the sample proportions, we divide the number of successes by the respective sample sizes:
p1 = X1 / n1 = 24 / 200 = 0.12
p2 = X2 / n2 = 17 / 150 = 0.1133
Now, we can plug these values into the formula to calculate the standard error:
SE = sqrt[(0.12 * (1 - 0.12) / 200) + (0.1133 * (1 - 0.1133) / 150)]
SE ≈ 0.0319
Finally, the test statistic (z-score) is calculated by subtracting the two sample proportions and dividing by the standard error:
Z = (p1 - p2) / SE
Z = (0.12 - 0.1133) / 0.0319
Z ≈ 0.2103
Therefore, the appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).

For how long will Zack have to make payments of $302.00 at the end of every year to repay a loan of $2355,00 i interest is 4% compounded annually? State your answer in years and months (from 0 to 11 month) Zack will have to make payments for year(s) and month(s)
Zack will have to make payments for approximately 6 years and 0 months (or 6 years if we round down).
To calculate the number of years and months Zack will have to make payments, we can use the formula for the present value of an annuity:
PV = PMT x [(1 - (1 + r)^-n) / r]
where PV is the present value of the loan, PMT is the payment made at the end of each year, r is the annual interest rate, and n is the total number of payments.
In this case, PV = $2355.00, PMT = $302.00, r = 4%, and we want to find n.
Substituting these values into the formula and solving for n, we get:
2355 = 302 x [(1 - (1 + 0.04)^-n) / 0.04]
7.796 = (1 - (1 + 0.04)^-n) / 0.04
(1 + 0.04)^-n = 1 - (0.04 x 7.796)
(1 + 0.04)^-n = 0.68304
-n x log(1.04) = log(0.68304)
n = -log(0.68304) / log(1.04)
n = 6.005
Therefore, Zack will have to make payments for approximately 6 years and 0 months (or 6 years if we round down).

Charlotte buys a ticket to go to a baseball game. The total includes a charge of 7% of the original price for extra fees. If Charlotte pays a total of $44.94, how much was the original price of the ticket?
Answer:
$41.7942
Step-by-step explanation:
First you need to change 7% into a decimal (you do this by dividing it by 100)
7÷100=0.07
Then, you multiply 0.07 with 44.94
0.07×44.94=3.1458
3.1458 is the amount for the extra fees.
After that, you subtract 44.94 with 3.1458
44.94-3.1458=41.7942
This gives us the original price, so, the original price is $41.7942.

The remaining 60 people get a lift in a car.
Calculate the number of pupils who get the bus and who walk to the cinema.
Answer: 48 pupils get the bus to the cinema and 36 pupils walk to the cinema.
Step-by-step explanation:
Let's suppose that there are a total of N pupils.
We know that N/4 walk to the cinema.
We know that N/3 get the bus to the cinema.
And the remainder is equal to 60 people.
Then:
N - N/4 - N/3 = 60
N*(1 - 1/4 - 1/3) = 60
N( 12/12 - 3/12 - 4/12) = 60
N*( 5/12) = 60
N = (12/5)*60 = 144
Then the number of pupils that walk to the cinema is N/4, or:
144/4 = 36

The value of the upper limit of the 4th class in the Frequency Distribution would be 66.
To determine the upper limit of the 4th class in the Frequency Distribution, we need to divide the range of the data into equal intervals. The range is the difference between the largest and smallest values in the data set, which in this case is 101 - 3 = 98.
Since we want to create 6 classes, we divide the range by the number of classes: 98 / 6 = 16.33 (approx).
To find the upper limit of the 4th class, we start with the lower limit of the first class, which is the smallest value in the data set, 3. Then, we add the interval width to the lower limit successively for each class.
The upper limit of the 1st class: 3 + 16.33 = 19.33 (approx)
The upper limit of the 2nd class: 19.33 + 16.33 = 35.66 (approx)
The upper limit of the 3rd class: 35.66 + 16.33 = 51.99 (approx)
The upper limit of the 4th class: 51.99 + 16.33 = 68.32 (approx)
Since we want the value of the upper limit of the 4th class, rounded to the nearest whole number, it would be 66.

Function 1 is defined by the equation y = \(\frac{5}{4}\)r - 1.
Function 2 is defined by line p, shown on the graph.
Which function has a greater slope.
Function 1 has a greater slope than Function 2, and the answer is Function 1.
Function 1 is defined by the equation y = \(\frac{5}{4}r - 1\).
Function 2 is defined by line p, which is shown on the graph.
The problem asks which function has a greater slope.
The slope of a line is calculated by the ratio of the difference between the vertical axis values and the difference between the horizontal axis values.
This is shown in the formula:
slope = rise/run.
Here, rise refers to the vertical difference and run refers to the horizontal difference.
This means that the slope of a line measures how steeply the line is increasing or decreasing.
Function 1: y = \(\frac{5}{4}r - 1\)
Here, the equation of Function 1 is given as y = \(\frac{5}{4}\)r - 1.
From this equation, we can see that the slope of Function 1 is equal to \(\frac{5}{4}\).
Therefore, the slope of Function 1 is 1.25.Function 2: Line pNext, we need to determine the slope of line p, which represents Function 2.
To do this, we can use two points on the line.
From the graph, we can see that the line passes through the point (0, -2) and the point (4, 1).
The rise of this line is equal to 1 - (-2) = 3, while the run is equal to 4 - 0 = 4.
Thus, the slope of line p is equal to 3/4.
Therefore, the slope of Function 2 is 0.75.
Comparing the slopes, we can see that Function 1 has a greater slope than Function 2.
Specifically, the slope of Function 1 is 1.25, while the slope of Function 2 is 0.75.
