When Mrs Munyai wanted to swim in her new pool, the temperature of the wate 19 °C and she said she would only swim if the temperature of the water was 25 °C temperature must increase by 6 °C. Calculate what the temperature change would be in °F. You may use the following formula: (°F-32) ÷ 1,8 = °C +
The temperature needs to be increased by \(10.8 ^{\circ}F\) for Mrs. Munyai to swim in the pool.
The formula to convert the temperature from Celcius to Fahrenheit is:
\(\textdegree F = (\textdegree C * 1.8) + 32\)
We need to calculate the temperature change of \(6 \textdegree C\) in Fahrenheit:
\(\Delta \textdegree C = 6\\\Delta \textdegree F = \Delta \textdegree C * 1.8 = 10.8\)
The temperature needs to be increased by \(10.8 ^{\circ}F\) for Mrs. Munyai to swim in the pool.
We can calculate the Fahrenheit temperature of the water and the desired temperature in Fahrenheit:
\(^{\circ}C = 19\\^{\circ}F = (19 * 1.8) + 32 = 66.2\)
\(^{\circ}C = 25\\^{\circ}F = (25 * 1.8) + 32 = 77\)
The current temperature of the pool is \(66.2 ^{\circ} F\) and the desired temperature is \(77 ^{\circ} F\).
Therefore the temperature needs to be increased by:
\(\Delta ^{\circ}F = 77 - 66.2 = 10.8 ^{\circ}F\)
which is the same temperature change we calculated earlier in Fahrenheit.
Therefore, the temperature needs to be increased by \(10.8 ^{\circ}F\) for Mrs. Munyai to swim in the pool.

y-3x=3 and x-2y=4 using elimination method
Answer:
x = -2, y = -3
Step-by-step explanation:
y - 3x = 3
x - 2y = 4
-3x + y = 3
x - 2y = 4
-6x + 2y = 6
x - 2y = 4
Add the equations.

A bag contains 4 red, 6 blue, 4 yellow and 2 green marbles. Once a marble is selected, it is not replaced. What is the probability that in 3 successive draws you will get exactly one blue, one red and no green
Answer:
0.0857
Step-by-step explanation:
What we need is, B R -G, successively. We do not add each probability, but multiply them.
P(1st marble is B) = 6 / 16
P(2nd marble is R) = 4 / 15
*your sample space decreases because you took one marble already before, the Blue one
P(3rd marble is not Green) = 12/14
** it's 12 because you took 2 non-Green marbles before
*** it's 14 because you took 2 marbles before
To arrive at the final answer, just multiply all probability.

5.6.8 let f be a uniformly continuous function on a set e. show that if {xn} is a cauchy sequence in e then {f(xn)} is a cauchy sequence in f(e). show that this need not be true if f is continuous but not uniformly continuous.
Proof. (1): To prove {f(xn)} is a Cauchy sequence just need to prove ∀ > 0, ∃N, s.t.,∀n, m > N,
have |f(xn) − f(xm)| < . Since f is uniformly continuous on set E, thus ∀ > 0, ∃δ > 0, s.t.,
∀x, y ∈ E, if |x − y| < δ,then |f(x) − f(y)| < .as {xn} is a Cauchy sequence, then ∃N, s.t.,
∀n, m > N, |xn − xm| < δ, thus |f(xn) − f(xm)| < which proves {f(xn)} is a Cauchy sequence.
(2): for example f(x) = 1

} is
a Cauchy sequence, however, {f(xn)} does not converge which proves that it is not a Cauchy
sequence.
Showing that this need not be true if f is continuous but not uniformly continuous.
Given :
let f be a uniformly continuous function on a set e. show that if {xn} is a cauchy sequence in e then {f(xn)} is a cauchy sequence in f(e).
( 1 )
If f is uniformly continuous on E, then given ε > 0 there is δ > 0 such that if x, y are in E and |x−y| < δ,
then |f(x) − f(y)| < ε. Let (xn) be a Cauchy sequence in E. Then given δ > 0 there is N such that if p, q > N,
then |xp − xq| < δ, and thus |f(xp) − f(xq)| < ε, implying that (f(xn)) is a Cauchy sequence.
( 2 )
Let E = {1, 1/2, 1/3, · · } and f(1/n) = 1 is n is odd, f(1/n) = −1 if
n is even. Then f is continuous but not uniformly continuous. The sequence (xn) = (1/n) in E is Cauchy but the
sequence (f(xn)) = (1, −1, 1, −1, · · ·) is not Cauchy.

can someone help me on this i’m stuck pleasee
Answer:
Data Set A = 6.5
Data Set B = 4
Step-by-step explanation:
The mean is just the average. It's calculated by adding up the scores and dividing the total by the number of scores in the group altogether.
For Data set A, you add 4 + 4 + 5 + 6 + 7 + 8 + 9 + 9 = 52
Then divide the total by how many numbers are in the set.
In this case, 52 ÷ 8 = 6.5
For Data set B, do the same. 3 + 3 + 3 + 4 + 4 + 5 + 5 + 5 = 32 32 ÷ 8 = 4

True or false? In a two-column proof, the left column states your reasons.
A. True
B. False
A. True.
In a two-column proof, the left column consists of statements, which are the facts or assumptions that lead to the proof of the theorem, while the right column consists of the reasons or justifications that explain how each statement logically follows from the previous one. Therefore, the left column states your reasons is a true statement.
The answer to the student's question is True. In a two-column proof, the left column contains the statements (steps) and the right column contains the corresponding reasons (justifications).
Explanation:The answer to the question, 'True or false? In a two-column proof, the left column states your reasons', is A. True.
A two-column proof is organized into two columns. The left column contains the 'Statements' and the right column contains the corresponding 'Reasons'. The 'Statements' are the steps that lead to the conclusion of the proof, while the 'Reasons' justify each of those steps according to rules or laws of mathematics.
For example, if we want to prove that the opposite angles of a parallelogram are equal. The left column (Statements) could contain the first step 'ABCD is a parallelogram' and the right column (Reasons) would give the explanation 'Given'. Therefore, in a two-column proof, the left column does represent statements, not reasons.

k) v=u+ax make x the subject
Answer:
x = (v - u) / a
Step-by-step explanation:
v = u + ax.
subtract u from both sides:
v - u = ax.
divide both sides by a:
(v - u) / a = x.
so x = (v - u) / a.
this can also be written v/a - u/a

<CED = 58°
Step-by-step explanation:
Let <CED = x
We can obtain the value of x as illustrated below:
<CED + 122 = 180 (angles on a straight line)
x + 122 = 180
Collect like terms
x = 180 – 122
x = 58°
<CED = x
x = 58°
Thus,
<CED = 58°
A one batch recipe of muffins makes a dozen muffins. it requires 2 eggs, two
cups of flour, and a 1\4 pound of sugar. There are 454 grams of sugar in a pound.
How many grams of sugar are in a muffin? **
Answer: 9.46 grams
Step-by-step explanation:
Given: Number of muffins made in one batch = 1 dozen =12 ]
[ as 1 dozen = 12]
Also, in one batch the quantity of sugar = \(\dfrac14\) pound
As there are 454 grams of sugar in a pound.
So, in one batch the quantity of sugar = \(\dfrac14\times454=113.5\ grams\)
i.e. in 12 muffins , there is 113.5 grams of sugar.
Then, in one muffin the quantity of sugar = (113.5 grams) ÷ 12
≈9.46 grams
Hence, there are 9.46 grams of sugar in 1 muffin.
Economists predict that Americans will spend $1,180 on Summer Vacation in 2015, this is up 3.4% from 2014. What did Americans spend in 2014?
With the help of percentage increase information, we conclude that, Americans spent approximately $1,141.31 on summer vacation in 2014.
What is percenatge increase?
Percentage increase is a measure of how much a value has increased in comparison to the original value, expressed as a percentage.
To find what Americans spent in 2014, we need to use the percentage increase and the 2015 amount.
Let X be the amount spent in 2014.
We know that the increase from 2014 to 2015 is 3.4%, which can be expressed as:
3.4% = 0.034 (as a decimal)
We also know that the amount spent in 2015 is $1,180.
Using this information, we can set up an equation:
X + 0.034X = 1180
Simplifying the left side:
1.034X = 1180
Dividing both sides by 1.034:
X = 1141.31
So Americans spent approximately $1,141.31 on summer vacation in 2014.

Identify the algebraic rule that would translate a figure 3 units left and 2 units up.
The algebraic rule for translating the figure 3 units left and 2 units up is (x-3, y+2). Option B.
To translate a figure 3 units to the left and 2 units up, we need to adjust the coordinates of the figure accordingly. The algebraic rule that represents this translation can be determined by examining the changes in the x and y coordinates.
When we move a figure to the left, we subtract a certain value from the x coordinates. In this case, we want to move the figure 3 units to the left, so we subtract 3 from the x coordinates.
Similarly, when we move a figure up, we add a certain value to the y coordinates. In this case, we want to move the figure 2 units up, so we add 2 to the y coordinates.
Taking these changes into account, we can conclude that the algebraic rule for translating the figure 3 units left and 2 units up is (x-3, y+2). The x coordinates are shifted by subtracting 3, and the y coordinates are shifted by adding 2. SO Option B is correct.
