To describe the temperatures for the week, we can apply the following statistical tools:
a) Find the mean, median, mode, and range.
c) Construct a line graph.
d) Construct a stem and leaf plot.
What are the statistical tools for describing temperatures?We can describe temperatures using measures of central tendencies (especially the mean, median, and mode).
The mean temperature is the average, which shows the overall trend in temperature changes. It is computed by adding up the temperatures for the period and diving by the number of data values.
In addition, the median gives the middle value when the data set is ordered in ascending or descending orders. Similarly, the mode gives the highest temperature occurrence within the period. It may not be useful here.
We can estimate the difference between the highest and lowest temperature for the week with the range.
A line graph (showing connecting lines) and a stem-and-leaf plot (like a bar graph) can graphically describe the temperatures for the week.
Thus, we can use Options A, C, and D to describe the temperature.

A Chevrolet Sonic Hatchback costs $14,800.00. With a 12 % down payment, you can have an amortized loan for 6 years at a rate of 4.5%. What will the monthly payment be? car cost in total, money paid in interest
Based on the loan amount and the number of years, the monthly payment, total cost of the car, and amount of interest to be paid are as follows:
Payment each month: $206.74Total cost of the car was $14, 885.$1, 861.52 must be paid in interest.How do I calculate the required interest?Find the loan amount first:
= Car expense x ( 1 - down payment percent)
= 14, 800 x ( 1 - 12%)
= $13024
the monthly rate and the total number of periods, then:
Daily rate calculation:
= Annual Rate / Twelve-Month Period
= 4.5% / 12
= 0.375%
Counting periods:
= Years multiplied by Months per year
6 years times 12
72 months
These enable the following formula to determine the monthly payment:
= Loan Amount / 72-period Annuity Present Value Interest Factor of 0.375%
13024 / 62.995976235992
= $206.74
Total amount repaid on the auto loan:
= Amount Due Each Month x The Number of Months
= 206. 74 x 72
= $14, 885. 52
Accordingly, the total amount of interest paid was:
= Amount borrowed - Amount paid toward the car's cost
= 14, 885.52 - 13, 024
= $1, 861.52

Thomas has $1,300 to paint the figure below. If it costs $5 for every square unit of paint, will Thomas have enough money to paint the entire surface area (outside only) of the figure?
Using the dimensions of the figure, Thomas will have enough money to paint the surface area.
What are the dimensions of a figure?The dimensions of a two-dimensional figure are its lengths and widths.
The product of the length and width results in the surface area, which is stated in square units.
How is the conclusion reached?Since Thomas has $1,300, and the squared surface of the figure is equal to 260 square units, when $5 is multiplied into 260, the product is $1,300.
This amount is equal to the money available to Thomas for the painting.
If the dimensions produced a surface area of more or less than 260 square units, we can calculate Thomas' ability to complete the painting based on the information.
The length of the figure is given as 20 units.
The width of the figure is given as 13 units.
The surface area of the figure = 260 square units
The cost of paint per square unit = $5
The total cost for painting the figure = $1,300 ($5 x 260)
The amount available to Thomas for the painting = $1,300
Difference between the total cost and the available amount = $0.
Thus, we can assert that, given the dimensions of the figure, Thomas can complete the painting with the available funds.

The diameters of cherry tomatoes produced by a large farm have an approximately Normal distribution, with a

greater than 25 mm?
Find the z-table here.
O 0.1151
O 0.1539
0.8461
0.8849
Hi, that would be option 3 if I am correct.
Hope this helps.
Answer:
0.8461
To find the proportion of cherry tomatoes that have a diameter greater than 25 mm, we need to determine the proportion of the distribution that falls above this value. We can do this by converting the diameter of 25 mm to a z-score using the formula:
z-score = (value - mean) / standard deviation
For a diameter of 25 mm, the z-score is (3 - 22) / 2.5 = -2.8.
We can then use a z-table to find the proportion of the distribution that falls above this value. The z-table gives the area under the standard Normal curve to the left of a given z-score. To find the proportion of the distribution above the diameter of 25 mm, we need to find the area to the right of -2.8. From the z-table, we find that the area to the right of -2.8 is 0.8461. Therefore, approximately 84.61% of cherry tomatoes produced by the farm have a diameter greater than 25 mm.

What is a function?A function is a relation where every input is connected to only one possible output from a set of available inputs.
The given function is C(x) = x² - 18x + 67.
To find the number of units manufactured at a cost of $8450, substitute C(x) = 8450 into the given equation and solve for x:
8450 = x² - 18x + 67
x² - 18x + 67 - 8450 = 0
x² - 18x - 8383 = 0
x² - 101x + 83x - 8383 = 0
x(x - 101) + 83(x - 101) =0
(x + 83)(x - 101) = 0
(x + 83) = 0 or (x -101) = 0

Solve for x and y 4x + 3y = -10 9x + 2y =6
Step-by-step explanation:
4x + 3y = -10
9x + 2y = 6
we have 2 general options :
substitution or elimination.
in substitution we use one equation to express one variable by the other, then use that equality in the second equation and solve for the remaining variable.
like in our case
4x = -10 - 3y
x = (-10 - 3y)/4
in elimination we multiply one or both equations by some factors and then subtract one equation from the other resulting in one equation in one remaining variable.
this is the better method, if substitution leads to more complex fractions.
like in our case.
so, I would multiply equation 1 by 2 and equation 2 by 3, and then subtract e.g. equation 2 from 1 (we could also do it the other direction, it gives the same solutions) :
8x + 6y = -20
- 27x + 6y = 18
------------------------
-19x 0 = -38
-19x = -38
19x = 38
x = 2
and then we pick any of the original equations to get the other variable :
e.g.
4x + 3y = -10
4×2 + 3y = -10
8 + 3y = -10
3y = -18
y = -6

Families at home = 10
So the ratio of the required families
= Families at home/total number of families
= 10/25
= 2/5
To convert the fraction into decimal form, we have to divide and we get
= 0.4
Hence, the number of families in decimal to which magazines got delivered are 0.4

When solving: 1,175 ÷ 5, using partial quotients, how would you decide which power of 10, when multiplied by 5, should be subtracted first?
I need a step by step example please
Using partial quotient, the place value while subtracting is determined by the dividend.
The place value should never be more than the dividend not up to a tens place value less than the dividend's place valueHow to perform division using partial quotientsdivisor dividend quotient multiplication subtraction new dividend
5 1175 200 200 * 5 = 1000 1175 - 1000 = 175
5 175 30 30 * 5 = 150 175 - 150 = 25
5 25 5 5 * 5 = 25 25 - 25 = 0
The quotient is then added as
= 200 + 30 + 5
= 235
Assuming the quotient was written 2. While subtracting, the dividend for the first value (1175) is in thousands. placing the the 2 in thousands makes it more than the dividend hence the 2 should be in hundreds
1175 - 2000 incorrect
1175 - 200 correct
for the second stage
175 - 150 correct (since 150 < 175)
last stage
