Answer: a) $778.67  b) 19 years

Step-by-step explanation:

The formula you would use is

[tex]a_{n}=P(1-r)^{n}[/tex]

where a is the amount

n is the length of time

P is the principle

and r is the rate in decimal form

a)

[tex]a^{12} =34,000(1-.27)^{12} \\a_{12}=34,000(.73)^{12}\\a_{12} =778.67[/tex]

b)

put your initial equation into a graphing calculator and  use the table function to find that after 18 years it is worth 117 and in 19 years 86-

Answer:

0.4629

Step-by-step explanation:

Using the binomial probability relation :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Number of trials, n = 25

Probability of having defective tablet greater than 3 p(x ≥ 3) ;

p = 0.10 ;

1 - p = 1 - 0.10 = 0.90

P(x ≥ 3) = P(x = 3) + p(x = 4) +.... + p(x = 25)

Using a binomial probability calculator :

P(x ≥ 3) = 0.4629

Therefore, the probability that shipment would be sent back to the vendor is 0.4629

Answer: a is 4 mm, c is 8 mm

Step-by-step explanation:

the 30-60-90 triangle rule: in a right triangle with 30, 60 and 90 degree angles, the adjacent side  is [tex]\sqrt{3}[/tex] the opposite side, while the hypotenuse is 2 times the opposite.

the adjacent side in this case would be 4[tex]\sqrt{3}[/tex], a is opposite, and c is the hypotenuse

divide the adjacent side by [tex]\sqrt{3}[/tex]  and we have the opposite side: 4

the hypotenuse is twice the opposite side, which has a value of 4. 4 times 2 is 8, which means the value of the hypotenuse is 8 mm

Answer:

C. 6(104)=624

Step-by-step explanation:

edge quiz

The equivalent expression of [tex]\sum \limits^{104}_{n = 1} {6}[/tex] is 6(104) = 24

The sigma notation is given as:

[tex]\sum \limits^{104}_{n = 1} {6}[/tex]

The above means that we add 6 in 104 places.

i.e. 6₁ + 6₂ + ................ + 6₁₀₄

The expression can be expressed using the following product

[tex]\sum \limits^{104}_{n = 1} {6} = 6 * 104[/tex]

Evaluate the product

[tex]\sum \limits^{104}_{n = 1} {6} = 624[/tex]

Hence, the equivalent expression of [tex]\sum \limits^{104}_{n = 1} {6}[/tex] is 6(104) = 24

Answer:

176.4m²

Step-by-step explanation:

scale factor = 7/5 = 1.4

area scale factor = 1.4² =1.96

90*1.96 =176.4m²

Answer: 176.4

Step-by-step explanation: (5/7)^2, cross multiply wit 90/SA, 90*49/25 = 176.4

Answer:

The area decreased by 329.7 square meters.

Step-by-step explanation:

For a circle of diameter D, the area is:

A = pi*(D/2)^2

with pi = 3.14

In this case, we start with a circle of D = 106m

Then the initial area is:

A = 3.14*(106m/2)^2 = 8,820.26 m^2

After, the diameter is decreased by two meters, then the new diameter is:

D' = 106m - 2m = 104m

And the new area will be:

A' = 3.14*(104m/2)^2 = 8,490.56 m^2

The change in the area is A - A' = 8,820.26 m^2 - 8,490.56 m^2 = 329.7m^2

The area decreased by 329.7 square meters.

The image of the labeled spinner isn't attached

Answer:

Kindly check explanation

Step-by-step explanation:

Answering hypothetically ;

First create a sample space using the label of the two spinners ;

Each space will be the sum of the possible number that shows up on each turn of the spinner.

From the sample space, count the number of spaces where, the sun is greater than 4, that is the required outcome ; = x

Then the total number of samples in the sole space = total possible outcomes = y

Hence,

P(obtaining a sum greater than 4) = required outcome / Total possible outcomes

= x / y

Step-by-step explanation:

Triangles ABC and DEF specified are similar triangles by Angle-Angle Similarity.

Two triangles are similar if two corresponding angles of them are of same measure. It is because when two pairs of angles are similar, then as the third angle is fixed if two angles are fixed, thus, third angle pair also gets proved to be of same measure. This makes all three angles same and thus, those two triangles are scaled copies of each other. Thus, they're called similar.

Sum of all angles of a triangle is 180 degrees.

For the triangle ABC, two of its angles are of 80 and 60 degrees, let its third angle be of D degrees, then:

[tex]80 + 60 + D= 180\\D = 180 - 60 - 80 = 40\text{\: \: (in degrees)}[/tex]

Since, triangle DEF also has two of its angles as 80 degrees and 40 degrees, thus, both the triangles ABC and DEF similar.

Answer:

C

Step-by-step explanation:

The equation for the dotted line is y=(-1/2)x, so therefore y<(-1/2)x must be the area under the dotted line.

The equation for the solid line is y=2x+3, so therefore y≥2x+3 must be the area above the solid line.

The section that is both under the dotted line and above the solid line is C.
