picking a purple marble from a jar with 10 green and 10 purple marbles

Answer: the total number is 1

Step-by-step explanation:

Counting by 1's from any integer involves enumerating individual units, making use of discrete data in our powers-of-ten notation system. Counting is a precise method of measurement, yielding an exact number. However, not all quantities derived from measurements are exact.

When you count by 1's from any integer, you are essentially enumerating individual units. This is related to the concept of quantitative discrete data in mathematics. Discrete data take on only certain numerical values. For example, if you count the number of fingers on your hand, you get integer values such as one, two, three, up to five.

In our powers-of-ten notation system, each place in our numbering is ten times greater than the place to its right. This system got started because we humans have ten fingers and began counting with them. So when you count by 1's, you are in fact moving from one place to another in this system, starting from the given integer.

Also, counting is a precise method of measurement. The number of items being counted does not change while the process is underway, producing an exact number. Even with counting, however, some quantities can be derived from measurements, which are not exact due to practical limitations.

Answer:

3 pallets

Step-by-step explanation:

Divide to find the amount of pallets:

Subtract Exponents to divide

15^13 / 15^5 = 13 - 5 = 8 - 5 = 4 (subtracted 2 times)

You need three to store ALL the water

The stock room will need [tex]15^8[/tex] pallets to store the received [tex]15^13[/tex] water bottles since each pallet can store [tex]15^5[/tex] water bottles and we divide the total number by the pallet capacity.

To calculate the number of pallets needed to store all the water bottles the stock room received, we need to divide the total number of water bottles by the number of bottles a single pallet can hold.

The pallet can store 155 water bottles, and the stock room receives 1513 water bottles. By dividing the total number of bottles by the capacity of a pallet, the calculation is:

1513 ÷ 155 = 1513-5 = 158

Therefore, the stock room will need 158 pallets to store all the received water bottles.

Chuck can afford both the convertible and sports car APEX

Step-by-step explanation:

Answer:

We can say that Chuck can afford both the cars.

Step-by-step explanation:

The EMI formula is :

[tex]\frac{p*r*(1+r)^{n} }{(1+r)^{n}-1 }[/tex]

p = 28700

r = 6/12/100=0.005

n = 6*12=72

Putting the values in the above formula, we get:

[tex]\frac{28700*0.005*(1.005)^{72} }{(1.005)^{72}-1 }[/tex]

Monthly payment is = $475.67

p = 29200

r = 6/12/100=0.005

n = 6*12=72

Putting the values in the above formula, we get:

[tex]\frac{29200*0.005*(1.005)^{72} }{(1.005)^{72}-1 }[/tex]

Monthly payment is = $483.96

We can see that in both the cases, the monthly payments or EMI's are less than $490.

Therefore, we can say that Chuck can afford both the cars.

Answer:

M<FDE = 360 degrees

Step-by-step explanation:

120 degrees is supplementary to x which makes it 120. 120+120=240 degrees. angle x and angle d = 120+120 which makes it 360 degrees.

M<ADE however, is 110+120=280, 360-280=80 degrees which is 110+120+80=360 degrees. So, M<ADE is 360 degrees and it is equal to M<FDE which is also 360 degrees.

All of them are equal. The sum of the figure is 720 Degrees.

Answer:

∠FDE = 130°

Step-by-step explanation:

Since BC and DE are parallel lines, then

∠BDE = ∠ABC = 110° ( corresponding angles are congruent )

The sum of the angles round a point = 360°, thus

∠BDE + ∠BDF + ∠FDE = 360 , hence

110 + 120 + x = 360

230 + x = 360 ( subtract 230 from both sides )

x = 130

Hence x = ∠FDE = 130°

Answer:

Angle A measures 180° - (24° + 55°) = 180° - 79° = 101°.

Angle x measures 360° - 101° = 259°.

Answer:

89.0°

Step-by-step explanation:

The measure of arc CD is the same degree measure as the central angle.

To find the central angle use the right triangle.

The segment from the centre to the chord is a perpendicular bisector, thus

the third side of the triangle = 12.7 ÷ 2 = 6.35

Calculate one half of the central angle using the sine ratio and multiply by 2 for the whole central angle

sin( one- half ) =[tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{6.35}{9.06}[/tex], hence

central angle = 2 × [tex]sin^{-1}[/tex] ([tex]\frac{6.35}{9.06}[/tex] ) ≈ 89.0°

Hence measure of CD ≈ 89.0°

Set u a ratio of height over shadow:

Lance = 5 feet tall / 8 foot shadow

Tree = X feet tall / 32 foot shadow.

Set the ratios equal to each other and solve for X:

5/8 = x/32

Cross multiply:

8x = 160

Divide both sides by 8:

x = 160/8

x = 20

The tree is 20 feet tall.

7 Hours on Average

add up all the hours and you get 35

then divide 35 by the number of given hours which is 5

35/5 = 7

so the average amount of hours slept was 7

Answer:

7 hours

Step-by-step explanation:

To find this average, add up the five data points given and divide your result by five (5):

(7 + 9 + 5 + 6 + 8) / 5 = 35 / 5 = 7

This group of students averaged 7 hours of sleep per night.

Answer: 26in

s=r*theta

r=s/theta

d=r*2

136ft=r*40pi

r=136/40pi=1.082ft

d=1.082*2=2.1645ft*(12in/1ft)=25.97in

Rounded to nearest in is 26in diameter

The diameter of the bike's tire is calculated by dividing the total distance traveled by the number of revolutions to find the circumference and then dividing the circumference by pi (π) to find the diameter, which is approximately 26 inches.

To find the diameter of the bike’s tire, given that it completes 20 revolutions and travels 136 feet, we can use the relationship between the circumference of a circle (in this case, the tire) and its diameter.

First, we calculate the circumference of the tire by dividing the total distance traveled by the number of revolutions:

Circumference = Total Distance ÷ Number of Revolutions

Total Distance = 136 feet (1 foot = 12 inches, so convert feet to inches for precision)

Total Distance in inches = 136 feet × 12 inches/foot = 1632 inches

Circumference = 1632 inches ÷ 20 = 81.6 inches

Now, we use the circumference to find the diameter:

Circumference = π × Diameter

Diameter = Circumference ÷ π

Diameter ≈ 81.6 inches ÷ π ≈ 26 inches

Therefore, the diameter of the bike’s tire, rounded to the nearest inch, is approximately 26 inches.

Answer:

A

Step-by-step explanation:

First, put this equation in slope intercept form.

[tex]y=mx+b[/tex]

Where m is the slope and b is the y intercept.

[tex]y+1>2(x-1) \\ \\ y+1>2x-2 \\ \\ y>2x-3[/tex]

Since it's greater than, the solution set is above the line, effectively eliminating graph D.

Now we should graph it.

We can see that the point [tex](2,1)[/tex] is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.

Answer:

A

Step-by-step explanation:

We can simply treat the inequality like an equation because the numbers are on the line. That is y + 1 = 2(x - 1).

Then, we can plug in some numbers:

If x = 2: y + 1 = 2(2 - 1)

y + 1 = 2

y = 1

So one point on the line is (2, 1). B, C, and D don't work because it is impossible for this point to be on the line; the x coordinate corresponds to another y-coordinate, or vise-versa ((3, 1), (2, 0) and (3, 1), respectively) . Therefore, the correct answer is A.

Answer:

D

Step-by-step explanation:

A is wrong because on the point -4, the function is equal to -12 and a states the local minimum on [-4, -2] is equal to zero. Since -12 < 0, A is wrong.

B is wrong because the function never even reaches 25 on the interval [-2, -2]

C is wrong because we can see that 3.9 is zero and the function is decreasing there. fro this we can determine the functions value at x = 4 is less than 0, meaning the minimum value is also less than 0.

Lastly, we can see that the lowest point fro 4 to 7 is at -7, meaning that D is correct.

Answer:

$29.02.

Step-by-step explanation:

We have been given that you save 3 ,260.00 in a savings account earning a 3.55% APR compounded monthly. We are asked to find the total interest earned by the end of the third month.

We will use compound interest formula to solve our given problem.

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,

A = Amount of interest after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of periods interest is compounded per year,

t = Time in years.

[tex]3.55\%=\frac{3.55}{100}=0.0355[/tex]

[tex]\text{3 months}=\frac{3}{12}\text{ year}=\frac{1}{4}\text{ year}[/tex]

Upon substituting our given values in above formula, we will get:

[tex]A=3,260(1+\frac{0.0355}{12})^{12\times \frac{1}{4}}[/tex]

[tex]A=3,260(1+0.002958333)^{3}[/tex]

[tex]A=3,260(1.002958333)^{3}[/tex]

[tex]A=3,260*1.00890128109888[/tex]

[tex]A=3289.0181763823\approx 3289.02[/tex]

Now, we will subtract principal amount from final amount to find amount of interest.

[tex]\text{Amount of interest}=3289.02-3260[/tex]

[tex]\text{Amount of interest}=29.02[/tex]

Therefore, you will earn am amount of $29.02 by the end of the third month.

Its used for the domain and it means "the members of all REAL numbers" which refers to their being no imaginary number, for instance in inequalities that have square roots, it cant be a negative number otherwise you will get a imaginary number.

Step-by-step explanation:

The 'z€ R' notation means 'z is an element of R' or 'z belongs to R', which signifies that the variable z is a part of the set of real numbers. This indicates the domain for the variable in an inequality. Also, the principle of the z-score in statistics describes how many standard deviations above or below the mean a certain value lies.

The notation z€ R in mathematical terms is used to indicate that the variable z belongs to the set of real numbers. Real numbers (often denoted by R) include all the numbers that can be shown on the number line; this set comprises rational (e.g., integers, fractions) and irrational numbers (like roots of numbers that are not perfect squares). When related to an inequality, this statement provides a domain of numbers that can satisfy said inequality, helping solve problems or equations.

A related concept is the z-score in statistics. The z-score tells you how many standard deviations a value is above or below the mean. Values larger than the mean have positive z-scores, but smaller values have z-scores that are negative. The absolute value of the z-score indicates the distance from the mean, irrespective of direction.

An example: a variable x in an equation can be represented in terms of z-score as x₁ = µ + zơ, which would mean that x is greater than the mean µ when z is positive, and less when z is negative.

The surface area of Figure 1 is 10.2 square centimeters Less than the surface area of Figure 2.

Step-by-step explanation:

Figure 1

area of a square = s2

=9squared

=81 sq cm

area of triangle = 1/2 bh

=1/2 (9cm) (14cm)

=63 sq. cm

find surface area

SA = 81 sq. cm + 4(63 sq. cm)

SA = 81 sq. cm + 252 sq. cm

SA = 333 sq. cm

Figure 2 Calculation

area of rectangle = lw

a = (12cm) (8 cm)

a = 96 sq. cm

area of triangle = 1/2 bh

=1/2 (8 cm) (6.9 cm)

= 27.6 sq. cm

total surface are of figure 2

SA = 3 (96 sq.cm) + 2 (27.6 sq. cm)

SA = 288 sq. cm + 55.2 sq. cm

SA = 343.2 sq. cm

find the difference between figure 1 and figure 2

343.2 sq. cm - 333 sq. cm = 10.2 sq. cm

Final answer:

We cannot complete the statement definitively about the surface area comparison between the square pyramid and the triangular prism without specific measurements. However, if we knew the dimensions, we could use the principle that surface area scales with the square of the linear dimensions to compare the two.

Explanation:

To complete the statement about the surface areas of Figure 1 (a square pyramid) and Figure 2 (a right triangular prism), we need to consider how areas scale with the dimensions of the shapes. Salviati's example illustrates that surface areas scale with the square of the linear dimensions, which is an important concept in geometry. Applying this concept to two triangles where one is larger than the other with linear dimensions twice as long, the larger triangle will have an area four times greater (area scales with the square of the linear dimensions).

Correct solution #1: Since the larger triangle's sides are twice as long, its area is 22 = 4 times more than the smaller triangle. If we applied similar reasoning and knew the dimensions of Figure 1 and Figure 2, we could compare their surface areas. However, with the provided information, we cannot definitively complete the given statement about the surface area of the pyramid relative to the prism without the specific measurements of each figure.

By understanding that the surface area of shapes scales with the square of their dimensions and using examples like cutting the larger triangle into four smaller ones (correct solution #2), we can tackle the surface area comparison confidently, provided we have the necessary dimensions.

70º

It's a supplementary angle so 180º - 110º

Answer:

a = 70

b=60

Step-by-step explanation:

Angle a and 110 are supplementary, which means they add to 180 degrees

a+ 110 = 180

Subtract 110 from each side

a+110-100=180-110

a = 70

The three angles of a triangle add to 180

a+ b+ 50 = 180

We know a = 70

70 + b + 50 = 180

120 + b = 180

Subtract 120 from each side

120-120 + b = 180-120

b = 60
