Answer:
Two solutions:
Adding 7 to the left and 0 to the right: 7920
Adding 2 to the left and 5 to the right: 2925
Step-by-step explanation:
The multiples of 45 always have as last digit 0 or 5, so the digit to the right of 92 has to be 0 or 5.
If we use 0 as the last digit, our options of multiples will be just 7920 (7920 = 45 * 176)
If we use 5 as the last digit, our option of multiples will be just 2925 (2925 = 45 * 65)
So we have just two solutions for this problem:
Adding 7 to the left and 0 to the right: 7920
Adding 2 to the left and 5 to the right: 2925

Zoya asked the students of her class their baseball scores and recorded the scores in the table shown below:
Baseball Scores
Based on the table, what is the mean baseball score?
Answer:
Correct answer is 4.1
Step-by-step explanation:
You have to list all scores, total them and then divide by the total count:
0,1,1,2,2,2,2,2,3,3,3,4,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,6,6,6,6,6
The sum is 134 divided by the total values in the data set, 33 = 4.1
To calculate the mean baseball score, add up all the scores and then divide by the number of scores. The example provided demonstrates this process with hypothetical scores.
Explanation:The mean is calculated by adding up all the scores and then dividing by the number of scores. Let's say the scores are 10, 20, 30, and 40. Here's how you calculate it:
Add up the scores: 10 + 20 + 30 + 40 = 100Count the number of scores. In this case, there are 4 scores.Divide the total by the number of scores: 100 ÷ 4 = 25. Therefore, the mean baseball score is 25.This method applies to any group of numbers, whether they are baseball scores or other data sets.

Students are selling pies for a school fundraiser. Customers can buy cherry pies and apple pies. Jennifer sold 12 cherry pies and 3 apple pies for a total of 144. Jacob sold 2 cherry pies and 9 apple pies for a total for 126
Answer: A cherry pie costs 9 and an apple pie cost 12
Step-by-step explanation:
Let an apple pie be represented by a
Let an cherry pie be represented by c
Jennifer sold 12 cherry pies and 3 apple pies for a total of 144. This can be written as:
12c + 3a= 144
Jacob sold 2 cherry pies and 9 apple pies for a total for 126. This can be written as:
2c + 9a = 126
12c + 3a= 144 ............. i
2c + 9a = 126 ........... ii
Multiply equation i by 2
Multiply equation ii by 12
24c + 6a = 288 ........ iii
24c + 108a = 1512 ...... iv
Subtract iv from iii
-102a = -1224
a = 1224/102
a = 12
An apple pie costs 12
From equation i
12c + 3a= 144
12c + (3×12) = 144
12c + 36 = 144
12c = 144 - 36
12c = 108
c = 108/12
c = 9
A cherry pie costs 9
The problem is about solving a system of linear equations. By assigning C to represent the price of a cherry pie and A to represent the price of an apple pie, we created two equations to reflect Jennifer and Jacob's pie sales. Then solve the equations.
Explanation:The subject of the school fundraiser problem is systems of linear equations. Applying the method of simultaneous equations, we can represent this problem with two equations. Let's represent the cost of a cherry pie as C and an apple pie as A.
For Jennifer's sales, we form the equation 12C + 3A = 144. For Jacob's sales, we form the equation 2C + 9A = 126. To solve this system of equations, we can use substitution or elimination. These equations are a representation of the fact that each pie type has a consistent price, irrespective of who is selling it or how many of each are sold.

[tex]f(x)=x^4+2x^3-9x^2+18x[/tex]
Step-by-step explanation:
Use grouping.
f(x) = x⁴ + 2x³ − 9x² + 18x
f(x) = x³ (x + 2) − 9x (x + 2)
f(x) = (x³ − 9x) (x + 2)
f(x) = x (x² − 9) (x + 2)

] Mr. Santiago received a job with an annual salary of $51,000. He will receive a 1.5% increase every year. How much will Mr. Santiago make in 3 years?
Answer:
He will make $53,330
Step-by-step explanation:
In this question, we are tasked with calculating how much Mr Santiago will make in three years.
To calculate the future value of his earnings, we can use the formula for the future value of the salary
Mathematically, the FV = I(1 + r)^t
Where I is the initial amount of $51,000
r is the interest rate which is 1.5% = 1.5/100 = 0.015
t is the time in years which is 3 years
We plug these values into the equation above;
FV = 51,000(1+0.015)^3
FV = 51000(1.015)^3
FV = 53,329.59 which is $53,330 to the nearest whole dollars

twice a number decreased by 20 is 50.
Answer:
The number is 35.
Step-by-step explanation:
Let the number be x
Twice the number: 2*x = 2x
Twice the number decreased by 20: 2x - 20
2x - 20 = 50
Add 20 to both sides
2x - 20 +20 = 50 + 20
2x = 70
Divide both sides by 2
2x/2 = 70/2
x = 35

At the gym, Ava swims every 10 days, runs every 4 days and cycles every 5 days. If she did all three activities today, in how many days will she do all three activities again on the same day?
Answer: After 20 days
Step-by-step explanation: you have to find the greatest common multiple so that the number is a multiple for each of them
since 10 is multiple of 5 you have to find the lcm of 10 and 4 or 5 and 4 which is still 20
so just multiply them and if she swims and does cycles every 10 days then you know that if she is swimming she is cycling, but if she is cycling she might not be swimming. So if running is 4 days then just multiply 4*5 = 20
Which inequality is true if p= 3.4?
A. 3p < 10.2
B. 13.6 < 3.9p
C. 5p > 17.1
D. 8.5 > 2.5p
The correct inequality is B. 13.6 < 3.9p.
Explanation:To determine which inequality is true if p = 3.4, we can substitute the value of p into each inequality and see which one is satisfied. Let's do this for each option:
A. 3p < 10.2:
Substituting p = 3.4, we get 3(3.4) = 10.2 < 10.2, which is not true.
B. 13.6 < 3.9p:
Substituting p = 3.4, we get 13.6 < 3.9(3.4) = 13.26, which is true.
C. 5p > 17.1:
Substituting p = 3.4, we get 5(3.4) = 17 < 17.1, which is not true.
D. 8.5 > 2.5p:
Substituting p = 3.4, we get 8.5 > 2.5(3.4) = 8.5 > 8.5, which is not true.
Therefore, the correct inequality is B. 13.6 < 3.9p.
5 less than 18 times the number x, is less than of equal to -45. write and inequality for this statement
Answer:
18x-5≤-45
Step-by-step explanation:
The statement '5 less than 18 times the number x is less than or equal to -45' translates to the inequality '18x - 5 ≤ -45'. This can be solved to yield 'x ≤ -20/9'.
Explanation:The phrase '5 less than 18 times the number x' can be written as an expression '18x - 5'. The complete inequality saying this is less than or equal to -45 can thus be written as '18x - 5 ≤ -45'.
To clarify, this means that if you were to multiply a number 'x' by 18, and then subtract 5, the resulting number should be less than or equal to -45.
This is a type of linear inequality and can be solved in a similar way to a linear equation. Subtracting 5 from both sides yields '18x ≤ -40', and then dividing by 18 gives the solution 'x ≤ -40/18' or 'x ≤ -20/9' in simplified form.

If ABCD is a rhombus AD=4x+2 DC=7x-13 and BD=34 find AE (E is in the middle)
Answer: Line AE equals 14 units (approximately)
Step-by-step explanation: If you have a rhombus given, it is important to begin by highlighting the properties of a rhombus. A rhombus first of all is four-sided shape with all sides congruent, then the two opposite sides are parallel and congruent. Also, the diagonals bisect each other into two equal halves each.
Therefore, we shall examine a rhombus labelled ABCD, with side AD measuring 4x + 2, and side DC measuring 7x - 13. Then BD is a diagonal from point B to point D, and it measures 34 units. Also a diagonal is drawn halfway from point A and stops at point E (E is in the middle), where it bisects diagonal BD into two halves. Remembering that all sides of a rhombus are equal, then note that AD equals DC, that is;
4x + 2 = 7x - 13
2 + 13 = 7x - 4x
15 = 3x
Divide both sides of the equation by 3
5 = x
If AD = 4x + 2, then when x = 5
AD = 4(5) + 2
AD = 20 + 2
AD = 22
Therefore triangle ADE can now be isolated with side AD measuring 22 units and side ED measuring 17 units (midpoint between points B and D). Line AE can be calculated using the Pythagoras theorem which states as follows;
AC² = AB² + BC²
Where AC is the hypotenuse, and AB and BC are the two other sides
Substituting for values as given in the question, we now have;
AD² = ED² + AE²
22² = 17² + AE²
484 = 289 + AE²
484 - 289 = AE²
195 = AE²
Add the square root sign to both sides of the equation
√195 = √AE²
13.96 = AE
Therefore line AE ≈ 14 units (to the nearest whole number)

LaTasha was presented with the following data set and argued that there was no correlation between x and y. Is LaTasha correct? Use the regression equation to explain your reasoning.
Answer:
LaTasha is correct. There is no correlation between x and y. The slope of the line of best fit is zero, which shows that there is no negative or positive correlation.
No, LaTasha is not correct. To determine whether there is a correlation between x and y, we need to use the regression equation and calculate the correlation coefficient.
Explanation:No, LaTasha is not correct. To determine whether there is a correlation between x and y, we need to use the regression equation. If the regression equation is significant and the correlation coefficient is significantly different from zero, then there is a linear relationship between x and y. If the correlation coefficient is not significantly different from zero, then there is no significant linear relationship. In this case, we need to calculate the correlation coefficient and see if it is significant.
To calculate the correlation coefficient, we use the formula r = √(SSR / SST), where SSR is the sum of squared residuals and SST is the total sum of squares. If the correlation coefficient is significantly different from zero, then there is a linear relationship between x and y.
In conclusion, we cannot determine if there is a linear correlation between x and y without calculating the correlation coefficient.

The function checks if the weight is less than or equal to 40 pounds and returns $20 in that case. If the weight is between 40 and 80 pounds, it calculates the additional cost by multiplying the excess weight (weight - 40) by $0.25 and adds it to the base cost of $20. If the weight exceeds 80 pounds, it returns a message indicating that the maximum weight limit has been exceeded.
