Answer:
When the survey was initially conducted, the average sales of smartphones was 1.7 million units.
Step-by-step explanation:
The exponential equation is P ( n ) = 1.7 ( b )ⁿ , where n is the number of years and P ( n ) is the annual sales of smartphones and the initial sales of smartphones was 1.7 million units
What is exponential growth factor?The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
P ( n ) = 1.7 ( b )ⁿ
where , n is the number of years
And , P ( n ) is the annual sales of smartphones
Now , the value of b is the exponential growth factor
At the initial year , the number of smartphones sold is when n = 0
So , when n = 0
P ( 0 ) = 1.7 ( b )⁰
P ( 0 ) = 1.7 million units
Hence , the number of smartphones sold in initial year is 1.7 million units

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up the Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century.

A rectangular fish tank is 22 inches tall. The base edge lengths are 20 inches and 18 inches. What is the total surface area of the fish tank?
Answer:
2392in^2
Step-by-step explanation:
Given data
Dimension
Height 22 inches
Lenght= 20inches
Width= 18inches
The expression for the total surface area is
TSA=2(lw + lh + wh)
Substitute
TSA=2(20*18+20*22+18*22)
TSA=2(360+440+396)
TSA=2*1196
TSA=2392 in^2
Hence the total surface area is 2392in^2
Juan decided to start savings for college. He deposited $500 into an account which earns 4% simple annual interest. At the end of each year, he will add $250 to this account. How much will he have in his account after the end of three years?
a
$550
b
$770
c
$1,050.80
d
$1,342.83
Answer
I am getting a different answer The reason being the first year we calculating the 4% of the initial amount of the $500 towards the end of the year if he deposits the 250 the second year he gets to have a 4% interest of the 750 in total If he deposits the 250 in the 3rd he gets to have a 4% of 1000 So if you actually calculate that and get the total of all the amount which is 1,000 plus the percentages of all that you get what I've shared
9514 1404 393
Answer:
d $1342.83
Step-by-step explanation:
At the end of the first year, the account balance will be $500 plus 4% interest on that amount, plus the $250 deposited at the end of the year:
$500(1.04) +250 = $770
At the end of the second year, the account balance will be $770 plus 4% interest on that amount, plus the $250 deposited at the end of the year:
$770(1.04) +250 = $1050.80
At the end of the third year, the account balance will be $1050.80 plus 4% interest on that amount, plus the $250 deposited at the end of the year:
$1050.80(1.04) +250 = $1342.83
_____
Additional comment
You can make an appropriate guess by realizing the total of the deposits is ...
$500 + 3×250 = $1250
Adding interest to that will increase the amount. The only answer choice greater than $1250 is $1342.83.

∠A and \angle B∠B are complementary angles. If m\angle A=(6x+22)^{\circ}∠A=(6x+22) ∘ and m\angle B=(7x+16)^{\circ}∠B=(7x+16) ∘ , then find the measure of \angle B∠B.
Answer: B = 44
Step-by-step explanation:
The measure of ∠B = 44°.
We have two angles ∠A and ∠B which are complementary of each other.
We have to find the measure of ∠B.
What are Complementary angles?Two angles are said to be complementary if their sum is equal to 90°.
Mathematically - x + y = 90°
According to the question -
∠A = (6x+22)°
∠B = (7x+16)°
Now, ∠A and ∠B are Complementary angles. Therefore -
∠A + ∠B = 90°
(6x + 22) + (7x + 16) = 90
13x + 38 = 90
13x = 52
x = 4
Therefore -
∠B = 7x + 16 = 7 x 4 + 16 = 44°.
Hence, the measure of ∠B = 44°.

Answer:
a. x = 22
b. Perimeter = 100
Step-by-step explanation:
a. Based on the proportionality theorem, we have the following:
(2x - 4)/8 = (36 - 6)/6
(2x - 4)/8 = 30/6
(2x - 4)/8 = 5
Cross multiply
2x - 4 = 8*5
2x - 4 = 40
2x = 40 + 4
2x = 44
x = 44/2
x = 22
b. Perimeter of ∆JKL = KJ + KL + JL
KJ = 2x - 4 + 8
Plug in the value of x
KJ = 2(22) - 4 + 8
KJ = 44 - 4 + 8 = 48
KL = 36
JL = 16
Perimeter = 48 + 36 + 16
Perimeter = 100
A number cube has 6 different faces, numbered 1 to 6. All faces have an equal probability of being rolled. What is the probability of rolling a 5?
please no links or weird pictures!
Answer:
its a 1/6 chance
Step-by-step explanation:
each face has a 1/6 chance of being rolled since there are 6 faces
Answer:
Answer:
40.2 % to the nearest tenth.
Step-by-step explanation:
Probability( 6 on one roll = 1/6).
Probability (6 on first roll and NOT 6 on the next 5 rolls) = 1/6 * (5/6)^6
= 3125/46656
= 0.06698
Only 1 six rolled can happen in 6 different ways ( where the 6 is on the second, third roll etc.)
So the required probability is 0.06698 * 6 = 0.40188.

Option 3
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
x² = (9.5)² + (10.5)²
x² = 200.5
x = √(200.5)
x = 14.16
x ≈ 14.2
Therefore, measure of the unknown side is 14.2 in.

Jarvis a 41-year old male, bought a $115,000, 20yr life insurance policy thru his employer. Jarvis is paid weekly. How much is deducted from each of his paychecks for life insurance?
Answer: $30.25
Step-by-step explanation:
Amount of insurance policy bought = $115,000
Number of years for the life insurance = 20 years.
From the chart, the Annual premium per $1000 of coverage for 20 years for a male of 40-44 years is $13.68. Therefore, the annual premium will be:
= (115,000 / 1,000) × $13.68
= 115 × $13.68 =
= $1,573.20
Note that 52 weeks make a year. Therefore, the weekly deductions will be:
= $1,573.20 / 52
= $30.25
Therefore, the correct option is D.
