Final answer:
To find out how many weights the personal trainer can purchase, subtract the cost of the weight bench from the budget and divide the remaining amount by the cost of each weight. The personal trainer can purchase 15 weights within the given budget.
Explanation:
To find out how many weights the personal trainer can purchase, we need to subtract the cost of the weight bench from the budget and divide the remaining amount by the cost of each weight.
Step 1: Subtract the cost of the weight bench ($500) from the budget ($860): $860 - $500 = $360.
Step 2: Divide the remaining amount ($360) by the cost of each weight ($24): $360 ÷ $24 = 15.
The personal trainer can purchase 15 weights within the given budget.
This budgeting approach demonstrates a systematic way for the personal trainer to allocate funds effectively, ensuring that both essential equipment and a sufficient quantity of weights can be acquired. By following these steps, the trainer maximizes the utility of the available budget, making informed decisions to support an efficient and well-equipped training environment.

It is the morning of the sandcastle-building competition at the beach. Dory has been looking forward to this event for months. According to her weather app, there is an 80% probability of high winds in her area today. Which of the following BEST describes the MOST likely way the probability was determined?
Answer:
B) Historically, in this area, high winds occur 80% of the time on days with similar meteorological conditions as today.
Explanation:
Meteorologists calculate the probability of certain weather conditions by dividing specific outcomes by the total number of possible outcomes. For example, to find out the probability of raining on a certain date, meteorologists use a large database which contains information about how many times it rained when the meteorological conditions were similar. If historically it rained during 5,000 days out of 8,000 total days that had a similar meteorological condition, then the probability of rain will be 5,000 / 8,000 = 62.5%

a group of 150 students were asked to identify 55 flowers. the relative frequency table shows the results. about how many students identified at least 35 flowers?
Answer:
55 Students identified at least 35 flowers.
Step-by-step explanation:
Here we have to ask at least 35 flowers, so there are only 3 classes. i.e. 35 - 41, 42 - 48, 49 - 55.
Thus, Number of Students identified at least 35 flowers is: 5 + 31 + 19 = 55
Further, Frequency is the number of repetitions of particular observation or class.
Relative frequency is the proportion of frequency. For finding the Relative Frequency divide the frequency of that observation or class to the total frequencies.

Louisa's savings change by -$9 each time she goes bowling.in all it changed by -$99 during the summer.how many times did she go bowling in the summer?
Answer:
She went 11 times.
Step-by-step explanation:
Given,
The change in saving in each time she goes bowling = -$ 9,
If she goes t times,
The change in saving for going t times = t × change in saving in each time
= t × -9
= -9t dollars,
According to the question,
-9t = -99
[tex]\implies t=\frac{-99}{-9}=11[/tex]
Hence, she went 11 times to bowling.

Using n = 4 equal-width rectangles, approximate the integral from negative 2 to 2 of the quantity x cubed plus 8, dx. Use the mid-point of each sub-interval to determine the height of each rectangle.
Answer:
32
Step-by-step explanation:
To solve this, you need to start by finding the width of the rectangles and the midpoints. If n=4, b=2, a=-2, and the width of each triangle is delta x = b-a / n, then each width is equal to 1 and there will be four midpoints (you can also tell the amount of midpoints by n=4). These midpoints are -1.5, -0.5, 0.5, and 1.5. The height of each of the rectangles is going to be equal to f(x*k), where x*k is the specific mid point. This means that you need to find f(-1.5), f(-0.5), f(0.5), and f(1.5). When putting these into the function you will get 4.625, 7.875, 8.125, and 11.375. Seeing as the Riemann Sum formula says the summation of f(x*k) * delta x, multiply each of the heights by the width of 1 and then add all of the values together. When you do this you will get 4.625 + 7.875 + 8.125 +11.375 which all totals to 32. This means that the approximation of the given integral is 32.

Which statement is always true for any parallelogram?
a. all four angles are right angles
b. the diagonals bisect each other
c. all four sides are congruent
d. the diagonals are congruent
The statement that is always true for any parallelogram is that the diagonals bisect each other.
Explanation:The statement that is always true for any parallelogram is b. "the diagonals bisect each other". To bisect means to divide into two equal parts. In a parallelogram, the diagonals (the line segments connecting opposite corners) will always divide each other into two equal parts. This can be proven by using properties of parallel lines and alternate interior angles.

For the following true conditional statement, write the converse. If the converse is also true, combine the statements as a biconditional.
If x = 7, then x2 = 49.
a. If x2 = 49, then x = 7. True; x^2 = 49 if and only if x = 7.
b. If x2 = 49, then x = 7. True; x = 7 if and only if x^2 = 49.
c. If x2 = 49, then x = 7. False
d. If x2 = 7, then x = 49. False
The converse of 'If x = 7, then x^2 = 49' is 'If x^2 = 49, then x = 7' which is considered true in the real number system. So, these can be combined as a biconditional: 'x = 7 if and only if x^2 = 49.'
The problem involves understanding the conditional, converse, and biconditional statements in mathematics logic. The initial conditional statement is 'If x = 7, then x^2 = 49.' We then need to assess the converse of this, which would be 'If x^2 = 49, then x = 7.' This converse statement is actually true, though it’s implied that we are dealing with real numbers. That’s because, in the real number system, when x^2 = 49, then x could technically be either 7 or -7.
However, because the original statement specified that x = 7 directly, we can say that both the conditional and converse are true. Therefore, these two statements can be combined as a biconditional. The biconditional statement, which is a statement that is accurate if both the conditional and converse are true, would be: 'x = 7 if and only if x^2 = 49.'

Deangelo has $7 worth of dimes and quarters in a jar. He has 7 more quarters than dimes. How many of each coin does he have? Enter your answers in the boxes. _dimes and _ quarters
Answer:
There are 15 dimes and 22 quarters in the jar.
Step-by-step explanation:
Deangelo has $7 worth of dimes and quarters in a jar.
Let he has d number of dimes and q number of quarters in a jar.
0.10d + 0.25q = 7 -------(1)
He has 7 more quarters than dimes.
q = d + 7 -------(2)
We replace the value of y from equation 2 in the equation 1
0.10d + 0.25(d + 7) = 7
0.10d + 0.25d + 1.75 = 7
0.35d = 7 - 1.75
0.35d = 5.25
d = [tex]\frac{5.25}{0.35}=15[/tex] dimes
Now we put this value in the equation number 2
q = 15 + 7 = 22
Therefore, number of dimes and quarters are 15 and 22 respectively.

Figure JKLM is a kite. What is the measure of angle K?
118 + 78 + 46 = 242
3 inside angles should equal 360 degrees
so angle K = 360 - 242 = 118 degrees
Answer:
(B) the measure of angle K=118°
Step-by-step explanation:
From the given figure, ∠KJM=78°, ∠JML=118°,∠MLK=46°
Now,since JKLM is a quadrilateral and we know that sum of all the angles of a quadrilateral is =360°, thus
∠KJM+∠JML+∠MLK+∠JKL=360°
⇒78°+118°+46°+∠JKL=360°
⇒242°+∠JKL=360°
⇒∠JKL=360°-242°
⇒∠JKL=118°
Thus, the measure of angle K=118°
