Answer: A. only II
Step-by-step explanation:
Mathematics calculus differentiates things into discrete and continuous. Discrete things have indivisible units, the example will be how many dogs in a village. There is no half dog, it's either one, two, etc. But the distance covered by train can be written as half miles, it's the divisible unit.
The number of books and bracelets also discrete, thus the answer is A.

Alfonso made a scale drawing of a tower. The actaul height of a tower is 25 feet. The scale Alfonso used in his drawing is 1 in.:10 ft. What is the height of the tower in Alfonso's drawing?
Answers
Answer:
2.5 inches
Step-by-step explanation:
Using Alfonso's scale of the drawing, which is 1in=10 ft, we can conclude the height of the tower to be 2.5 inches because
the actual height of the tower is 25 feet
10+10=20, which by following the scale, is 2 inches
we then have 5 left, 5 being half of 10, and .5 being half an inch.
Therefore the height of the tower using Alfonso's scale is 2.5 inches.
Hope this helps and take care
Suppose the class sizes in high schools in a major public school district are normally distributed with an unknown population mean and standard deviation. If a random sample of 28 high school classes is taken to estimate the mean class size, use a calculator to find the t-score that should be used to find a 90% confidence interval estimate for the population mean.
Answers
Answer:
1.703
Step-by-step explanation:
The reason we try to find t score is because the sample size is below 30, meaning the sample size is small
Hence:
Step 1
We find the degree of freedom
The Degrees of freedom = Number of samples - 1
The random number of samples = 28
= 28 - 1
= 27
Step 2
Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27
90% confidence interval =
10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail
Hence: t90 = 1.703

For a standard normal distribution, find:______. P(z < -0.34) Express the probability as a decimal rounded to 4 decimal places.
Answers
Answer:
36.69%
Step-by-step explanation:
Given a standard normal distribution :
P(Z < - 0.34) :
Using the Z distribution table :
Look up the value - 0.3 down the row and 0.04 a cross the column. The value at the intersection of the two points gives the required proportion:
P(Z < - 0.34) = 0.3669
0.3669 as a percentage = 0.3669 * 100% = 36.69%
The value can also be obtained using the Z probability calculator.

If ABC is reflected across the y-axis, what are the coordinates of C?
Answers
Answer:
C
Step-by-step explanation:
The y axis is vertical so you only change the x value.
The coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have a triangle shown on the coordinate plane.
If ABC is reflected across the y-axis,
Then the coordinate of C
From the figure, the coordinate of C is(before reflection)
C = (6, 3)
The rule for transformation if reflected across the y-axis:
(x, y) → (-x, y)
(6, 3) → (-6, 3)
Thus, the coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.

A local grocery store received a new shipment of apples. The apples arrived in 8 crates with 20 apples in each crate. If the store pays $0.21 per apple and sells each apple for $0.79, what would the profit be after selling all of the apples?
A.
$16.24
B.
$22.12
C.
$92.80
D.
$126.40
Answers
The correct answer is C. $92.80
Explanation:
The first step is to calculate the profit for each apple, this can be found by subtracting the cost the store pays from the selling price.
$0.79 - $0.21 = $0.58
This means for each apple the store sold, the profit (amount of money earned) is $0.58. Now, let's find the total apples the store received, and therefore the total of apples the store can sell.
8 creates each with 20 apples
8 x 20 = 160 apples
Finally, multiply the profit for selling one unit by the total apples
160 x 0.58 = $92.8

Find the total amount given the original price, tax rate and tip rate. Round to the nearest hundredth if necessary.
Original price: $101.33
Tax rate: 6.7%
Tip: 18%
Answers
Answer:
The total cost would be $126.36
Step-by-step explanation:
18% plus 6.7% is 24.7%. 24.7% of 101.33 is 25.028. Add $101.33 and $25.03
The total amount including tax rate and tip rate is $127.58.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The original price is $101.33.
Now, Tax rate is 6.7%.
Price with tax is,
= (106.7/100)×101.33.
= $108.12.
The price with tip is,
= (118/100)×108.12.
= $127.58.
So, The total price is $127.58.

1+n/7=3
A. Do the reciprocal of 1/7
B. Divide both sides by 7
C. Multiply both sides by 7 for the inverse
D. Subtract 1 on both sides for the inverse
Answers
Answer:
C.
Step-by-step explanation:
I'm assuming that the equation is (1+n) / 7 = 3, where 1+n is the numerator and 7 is the denominator.
In this case, to isolate for n, you have to multiply both sides by 7.
then you get 1+n = 3/7, and then you can get n = 3/7 - 1

Step-by-step explanation:
The annuity and amortization formulas are used for problems like this.
sum of monthly payments = P((1 +r/12)^(12t) -1)/(r/12)
monthly amount available = P(r/12)/(1 -(1 +r/12)^(-12t))
__
12. The sum of monthly payments of 74, accumulated at 9% compounded monthly for 52 years is ...
A = ($74)((1 +.09/12)^(12·52) -1)/(.09/12) = $1,035,057.23
__
13. The total of payments is ...
$74×12×52 = $46,176
So, the interest earned is ...
$1,035,057.23 -46,176 = $988,881.23
__
14. The amount available in perpetuity is the monthly interest on this account balance.
$1,035,057.23 × .09/12 = $7,762.93
__
15. The monthly amount available for 25 years is found from the amortization formula:
A = $1,035,057.23(.09/12)/(1 -(1 +.09/12)^(-12·25)) = $8686.16
__
16. The amortization formula is used for this, too.
8066 = P(.094/12)/(1 -(1 +.094/12)^(-12·30)) = 0.00833568P
P = $8066/0.00833568 = $967,647.66
