A cyclist rides her bike at a rate of 10 kilometers per hour what is this rate in miles per hour? How many miles will the cyclist travel in 3 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers l. Do not round your answers
Answers
Answer:
cyclist will travel 64 kilometres in 4 hours
Step-by-step explanation:
speed of cyclist = 10 miles per hour
given 1 mile is equal to 1.6 kilometres.
1*10 miles will be equal to 1.6*10 kilometres
thus , 10 mile is equal to 16 kilometres
using 16 km in place of 10 miles in 10 miles per hour
we have
speed of cyclist = 16 kilometres per hour
we know that distance = speed * time
speed is 16 kilometres per hour
time 4 hours
thus , distance = 16*4 kilometres= 64 kilometres.
cyclist will travel 64 kilometres in 4 hours.

A local school board wants to determine if the proportion of households in the district that would support starting the school year a week earlier has changed from the previous year. Last year, the school board determined that 65% of households supported starting school earlier. They ask a random sample of 100 households this year, and 70% state they would support starting the school year earlier. The P-value for the test of the hypotheses, H0 p = 0.65 and H, p *0.65, is 0.29. What is the correct interpretation of this value?
A. Only 29% of households in this sample approve of starting school earlier.
B. Assuming 65% of households would support starting school earlier, there is a 0.29 probability of getting a sample proportion of 0.70 or more different from 0.65.
C. Assuming 65% or more households would support starting school earlier, there is a 0.29 probability of getting a sample proportion of 0.70 or more different from 0.65.
D.Assuming this sample was collected correctly, the probability of getting 70 households out of 100 that would support starting school earlier is 0.29 if 65% of households truly support starting school earlier.

State the domain and range for the following relation. Then determine whether the relation represents a function.{(8,-7)}, (9,7), (10,-7),(11,-7)}
Answers
Domain: 8, 9, 10, 11.Range: -7, 7 This relation does not represent a function because the same x-value (8, 10, 11) is associated with more than one y-value (-7, 7).
Domain: 8, 9, 10, 11
Range: -7, 7
A function is a relation between a set of inputs and a set of outputs such that each input is associated with exactly one output. This particular relation fails to meet this condition because the domain value 8 is associated with two different range values (-7 and 7). In other words, the same input (8) is associated with two different outputs, which means the relation does not represent a function. The domain of the relation is 8, 9, 10, 11 and the range is -7 and 7. Therefore, this relation does not represent a function because it violates the condition that each input must have one and only one associated output.

Explain how you know that (3, 5) is not a solution to the given inequality by looking at the graph.
Answers
The reason that the point (3, 5) is not a solution to the given inequality is given below.
We are given that;
y > 2x + 1
Now,
The inequality y > 2x + 1 can be graphed by first graphing the boundary line y = 2x + 1. Since the inequality is strict (y >), we draw a dashed line to indicate that points on the line are not solutions to the inequality. Then, we shade the region above the line to indicate all points that satisfy the inequality.
If we have (3,5) as a point, we can see that it lies on the boundary line
y = 2x + 1.
Since the inequality is strict (y >), points on this line are not solutions to the inequality
Therefore, by the inequality the answer will be given above.

Two friends Rohan and Sam started a business together. They decided to share their profit
based on their expenditure. The profit of the two partners together is given by the polynomial
6x
2 + 11x – 35, which is the product of their individual share factors.
On the basis of the above information, answer the following questions.
Q.11 The total profit, when x = 10 is
A 375 B 475 C 575 D 675
Q.12 The possible expressions for the individual share are
A 2x + 5, 3x - 7 B 3x – 5, 2x + 7 C 2x – 7, 3x + 5 D 2x – 5, 3x + 7
Q.13 The value of x, when their shares are equal is
A 12 B 10 C 8 D 6
Q.14 The sum of their shares is given by
A 5x - 2 B 5x + 2 C x - 2 D x + 12
Answers
Profit function is the difference between the revenue function, and the cost function
The polynomial that represents their share factor is given as:
\(P(x) = 6x^2 + 11 x - 35\)
Q1. The total profitThis means that we calculate P(10).
So, we have:
\(P(10) = 6(10)^2 + 11(10) - 35\)
\(P(10) = 675\)
Hence, the total profit when x = 10 is (d) 675
Q2. The possible expressionsWe have:
\(P(x) = 6x^2 + 11 x - 35\)
Factorize the above expression
\(P(x) = (2x + 7)(3x - 5)\)
Hence, the possible expressions for the individual shares are (b) 3x - 5 and 2x + 7
Q3. Equal sharesWhen their shares are equal, we have:
\(2x + 7 = 3x - 5\)
Collect like terms
\(3x - 2x = 7 + 5\)
\(x =12\)
Hence, the value of x when their shares are equal is (a) 12
Q4. The Sum of their sharesThe sum of their shares is represented as:
\(Sum = 2x + 7 +3x - 5\)
Collect like terms
\(Sum = 2x +3x + 7 - 5\)
\(Sum = 5x+ 2\)
Hence, the sum of their shares is (b) 5x + 2

Answers
The joint relative frequency for school children who plan to attend camp and have swimming lesson is 44%.
The correct option to the given question is option d.
We are required to find the joint relative frequency for school children who plan to attend camp and have swimming lessons, rounded to the nearest percent.
To find the joint relative frequency, we use the formula as follows:
Joint relative frequency = frequency of interest / total frequency
Joint relative frequency for school children who plan to attend camp and have swimming lessons = 42 / 96
(As we are looking for the students who plan to attend camp and have swimming lessons, we are interested in the first column of the table and the entry at the intersection of the first row and second column.)
Joint relative frequency for school children who plan to attend camp and have swimming lessons = 0.4375
Joint relative frequency for school children who plan to attend camp and have swimming lessons (rounded to the nearest percent) = 44%(option d).

Admission to a baseball game is $4.00 for general admission and $6.50 for reserved seats. The receipts were $4589.50 for 988 paid admissions. How many of each ticket were sold?
Answers
There were 733 general tickets sold and 255 reserved tickets.
How to calculate the values?Let the general admission = g
Let the reserved seats = r
Therefore, the appropriate equation will be:
g + r = 988
4g + 6.5r = 4589.50
From equation i r = 988 - g
4g + 6.5r = 4589.50
4g + 6.5(988 - g) = 4589.50
4g + 6422 - 6.5g = 4589.50
6.5g - 4g = 6422 - 4589.50
2.5g = 1832.50
g = 1832.50/2.5
g = 733
Since g + r = 988
r = 988 - 733
r = 255
Therefore, there were 733 general tickets sold and 255 reserved tickets.

In the triangle, we have the opposite side and the hypothenuse. We can find the adjacent side using Pythagoras theorem.
Substituting the values into the formula;
w² = v² + x²
(√71)² = (√7)² + x²
71 = 7 + x²
x² = 71 - 7
