Isabel and Khalil buy peaches and apricots. At the fruit stand, peaches cost $0.85 each, and apricots cost $0.55 each. Tax is included in the cost of each fruit. The friends have $5 to spend. Which is a possible combination of the number of peaches and apricots they can get for $5? Responses 1 peach, 8 apricots 1 peach, 8 apricots 2 peaches, 5 apricots 2 peaches, 5 apricots 3 peaches, 7 apricots 3 peaches, 7 apricots 4 peaches, 3 apricots 4 peaches, 3 apricots
The possible combination of the number of peaches and apricots they can get for $5 is 2 peaches and 5 apricots.
What is the possible combination?The equation that represents the total cost of peaches and apricots is:
Total cost = (number of peaches x cost of one peach) + (number of apricots x number of apricots)
$5 = ($0.85 x p) + ($0.55 x a)
Total cost of buying 1 peach and 8 apricots:
($0.85 x 1) + ($0.55 x 8) = $5.25
Total cost of buying 2 peaches and 5 apricots:
($0.85 x 2) + ($0.55 x 5) = $4.45
Total cost of buying 3 peaches and 7 apricots:
($0.85 x 3) + ($0.55 x 7) = $6.40
Total cost of buying 4 peaches and 3 apricots:
($0.85 x 4) + ($0.55 x 3) = $5.05

Part A: Using computer software, a correlation coefficient of r= 0. 01 was calculated. Based on the scatter plot, is that an accurate value for this data? Why
or why not? (5 points)
Part B. Instead of comparing the number of strawberries picked and the day in February, write a scenario that would be a causal relationship for
strawberries picked on the farm. (5 points)
Part A:because the data points are far away from each other.
Part B: A casual relationship would be: the number of strawberries picked and the amount of fertilizers used.
What is Correlation Coefficient?
Correlation coefficient, r, is quantitative measure that measures the extent to which two variables are associated.
The closer the data points are on a scatter plot, the closer the value of r is to 1 or -1.
Part A:
The data points in the scatter plot are farther apart and the trend slopes upwards to the right, this means that the correlation coefficient, r, would be positive but very low.
Thus, based on the scatter plot given, the correlation coefficient of r = 0.01 is most likely accurate because the data points are far away from each other.

Two of the exterior angles of an n-sided polygon are 25° and 26°, three of its interior angles are 161° each and the remaining interior angles are 159° each. Calculate the value of n.
The required value of the number of sides ( n ) is 17.
What is polygon?
A closed, two-dimensional object composed of straight lines is called a polygon. In most cases, we can quickly determine the polygon's number of sides from its name.
Given, two of the exterior angles of an n-sided polygon are 25° & 26°
So, the sum of exterior angle = 25° + 26° = 51°
three of its interior angles are 161º each
So, each exterior angle = 180° - 161° = 19° .
sum of three exterior angles = 19*3 = 57° .
Then,
Remaining total angles = n - (2 + 3) = (n - 5).
And, the remaining interior angles are 159° each.
So, each exterior angle of the remaining angles = 180° - 159° = 21°.
sum of all (n -5) exterior angles remaining = 21(n - 5) = (21n - 105°) .
Now,
Sum of all exterior angles = 360°
or, 51° + 57° + (21n - 105°) = 360°
or, 21n + 108° - 105° = 360°
or, 21n + 3° = 360°
or, 21n = 360° - 3°
or, 21n = 357°
or, n = 357/21 = 17
Hence, The required value of n is 17.

Answer :
9 girls and 18 boys don't have a voucher
Step-by-step explanation :
There are 38 boys and 22 girls. The total number of children is 60. We know that 33 children have a voucher. 27 children don't have a voucher. ( 60 - 33 = 27 ) .
"Twice as many boys as girls do not have a voucher."
We can now make an equation.
The girls who do not have a voucher will be x, boys who don't have a voucher will be 2x, since it says twice as many boys.
We can now make our equation.
x + 2x = 27
Add x and 2x
3x = 27
Divide both sides by 3
x = 9
We know now that girls who don't have a voucher is 9.
The boys who don't have a voucher is 2x, so we plug 9 instead of x.
2(9) = 18.
18 boys do not have a voucher.

Jerome invested 260000 for 2 years at a rate of 8%p.a. 1)calculate the simple interest 2)calculate the investment at compound interim interest 3)amount at the end of the simple interest 4)amount at the end of compound 5)difference between the amount at simple interest and compound interest
1) Simple interest is $41600, 2) compound interest is $ 43264, 3) Amount at the end of Simple interest is $301600, 4) Amount at the end of Compound interest is $303264, 5) Difference in the amount of simple and compound interest is $ 1664.
Here it is given:
Principle (P) =$ 260000
Time(t) = 2 years
Rate (R) = 8%
1) We have to find the simple interest:
Simple interest(SI) = P× t × R/ 100
= 260000× 2× 8/ 100
= $41600
2) We have to find Compound Interest
Compound interest(CI) =P( 1 + R/100[tex])^{t}[/tex]- P
= 260000( 1 + 8/100[tex])^{2}[/tex]- 260000
= 260000( 27/25[tex])^{2}[/tex] - 260000
= 303264 - 260000
= $43264
3) Amount at the end of simple interest
Amount = P + SI
= 260000 + 41600
=$301600
4) Amount at the end of compound interest
Amount = P + CI
= 260000+ 43264
= $303264
5) Difference between the amount at simple interest and compound interest
Difference = 303264 - 301600
= $1664
Therefore the simple interest is $41600, the compound interest is $43264, the Amount at the end of simple interest is $ 301600, the amount at the end of the compound interest is $303264, and the difference in the amount of simple interest and compound interest is $1664.

How long would the minute hand of a clock have to be if its end were to move at 100km/hour?
To move at 100 km/hour at its end, the length of the minute hand that has an angular velocity of 2·π radians per hour, has to be approximately 15.92 kilometers
What is angular velocity?Angular velocity is the rate and direction of rotation of a body about an axis.
The required linear speed of the minute hand = 100 km/hour
The formula to convert angular speed to linear speed is presented as follows;
[tex]\omega = \dfrac{v}{r}[/tex]Which gives;
[tex]r = \dfrac{v}{\omega}[/tex]The angular speed of the minute hand = 2·π rad/hour
The required length of the minute hand is therefore;
[tex]r = \dfrac{100 \ km/hour}{2\cdot \pi/hour} = \dfrac{50}{\pi}\, km \approx 15.92 \, km[/tex]

Determine whether each statement is always, sometimes, or never true.
13. For a 0, the value of a¹ is positive. ●
14. If n is an integer, then 3" 3" equals 1.
15. If 6P 0, then p > 0. 16. 4* equals 1. 4*
17. If m is an integer, then the value of 2m is negative
Problem 13
Answer: Sometimes trueReason:
If a > 0, then the statement would always be true. However, if 'a' was negative, then the statement is false.
For example, if a = -2 then:
[tex]a^{-1} = (-2)^{-1} = \frac{1}{(-2)^1} = -\frac{1}{2} = -0.5[/tex]
In short,
[tex]a^{-1} = -0.5 \ \ \text{ when } a = -2[/tex]
This is one of infinitely many counter-examples to prove the original statement isn't always true.
===================================================
Problem 14
Answer: Always trueReason:
The rule to use here is [tex]a^b*a^c = a^{b+c}[/tex]
We add exponents b and c, while the base 'a' stays the same the whole time.
In this problem we have: [tex]3^n*3^{-n} = 3^{n+(-n)} = 3^{n-n} = 3^0 = 1[/tex]
Therefore [tex]3^n*3^{-n} = 1[/tex] is always true regardless of what you replace n with. The variable n doesn't have to be an integer.
===================================================
Problem 15
Answer: Sometimes trueReason:
Let's say p = -1 is plugged into the expression
[tex]6^p = 6^{-1} = \frac{1}{6^1} = \frac{1}{6} \approx 0.1667[/tex]
which is a positive outcome showing that [tex]6^p > 0[/tex] doesn't automatically guarantee that p > 0. Feel free to try other negative values as counter-examples. Also p = 0 works as well. It turns out that [tex]6^p[/tex] is always positive regardless of what real number you use for p.
===================================================
Problem 16
Answer: Always trueReason:
The rule used here is [tex]a^{-b} = \frac{1}{a^b}[/tex]
An equivalent rule is [tex]\left(\frac{a}{b}\right)^{-c} = \left(\frac{b}{a}\right)^c[/tex]
The idea is to flip the fraction to turn the exponent positive.
Examples: [tex]2^{-5} = \frac{1}{2^5} \ \ \text{ and } \ \ \left(\frac{7}{9}\right)^{-3} = \left(\frac{9}{7}\right)^{3}[/tex]
===================================================
Problem 17
Answer: Never trueReason:
This is similar to problem 15 in that [tex]2^m[/tex] is always positive regardless if m is negative, zero, or positive. It might help to graph out [tex]y = 2^x[/tex] and see that the curve never dips below the x axis.
