Answer:

238 times

Step-by-step explanation:

Given

[tex]a = 175[/tex] -- first week

[tex]r = 16.5\%[/tex]--- growth per week

[tex]t = 2[/tex] --- time

Required

The number of times it was downloaded in 2 weeks

An exponential growth is represented as:

[tex]y = a(1 + r)^t[/tex]

So, we have:

[tex]y = 175 * (1 + 16.5\%)^2[/tex]

[tex]y = 175 * (1.165)^2[/tex]

[tex]y = 175 * 1.357225[/tex]

[tex]y = 237.514375[/tex]

[tex]y = 238[/tex] -- approximated

1/2*1/2*1/2*1/2= [tex]\frac{1}{2} ^{4}[/tex]  Which is apparently none of these answers since it’ll be 1/16.

(Did you make a mistake with 5/16?)

☆☆●◉✿Step-by-step explanation:✿◉●☆☆

I know it is not 4/48 because that’ll be 1/12.

I know it would not be 1/20736 because the number is too small.

I know it would not be 4/12 beacuse that’ll be 1/3

And Iast but now Ieast I know it wouldn’t be 5/16 because that cannot be simplified.

Answer:

the answer is A on Edge

A) The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9.

Step-by-step explanation:

took the quiz :)

The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9 is the correct statement.

We have given that,

lim g(x)

X-3

The application of results concerning partial limit laws of normed sums of independent and identically distributed random variables will be obtained.

Therefore from the graph, we can say that option A is correct.

Answer:

c

Step-by-step explanation:

The test which scores are better than the percentage of all scores will be tested 2 and the percentage is 3. Hence, option B is correct.

A probability distribution that is symmetric around the mean and demonstrates that data close to the mean are more likely to occur than data distant from the mean.

As per the given information in the question,

1.

x = 65

Mean,  μ = 70

Standard deviation, σ = 3

Use the equation given below to find the percentage,

Z = (x - Mean)/Standard deviation,

Z = (64 - 70)/3

= -6/3

Z = -2

2.

x = 80

Mean,  μ = 50

Standard deviation, σ = 10

Use the equation given below to find the percentage,

Z = (x - Mean)/Standard deviation,

Z = (80 - 50)/10

= 30/10

Z = 3

Compare the values obtained, and it is clear that Test 2 got height score.

Answer:

D. (4,3)

Step-by-step explanation:

I calculated it logically

Solution :

Mean time for an automobile to run a 5000 mile check and service = 1.4 hours

Standard deviation = 0.7 hours

Maximum average service time = 1.6 hours for one automobile

The z - score for 1.6 hours = [tex]$\frac{1.6-1.4}{0.7 / \sqrt{50}}$[/tex]

                                           = 2.02

Now checking a normal curve table the percentage of z score over 2.02 is 0.0217

Therefore the overtime that will have to be worked on only 0.217 or 2.017% of all days.

Answer:

It is 40 degrees

Step-by-step explanation:

The 2 lines, x and y are forming 90 degrees, and since we know that part of that complementary angle is 50 degrees, we would do:

50+x=90

-50    -50

-------------

x=40

Answer:

38°

Step-by-step explanation:

90= (8+3x) + 52

38= 8 +3x

30= 3x

10= x

Answer:

Option A, Shannon paid $ 7 per hour to labor than Joni

Step-by-step explanation:

Total amount paid by Shannon = $339.50

Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)

Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5

Total cost of 1 hours of labor paid by Shannon  $65 per hour

Total amount paid by Joni = $455

Total cost of 2.5 hours of labor paid by Joni =  $455- $$310

Total cost of 1 hours of labor paid by Joni = $145/2.5

Total cost of 1 hours of labor paid by Joni = $ 58

Hence, Shannon paid $ 7 per hour to labor than Joni

Option A is correct

Answer:

B. x = 0.14

Step-by-step explanation:

Inx = -2

x = e^(-2)

x = 0.135

x = 0.14 (to two d.p)

The solution of the equation ln x =-2 is 0.14

The correct option is (D)

Logarithms are the inverse of exponents.

Given that:

ln x =-2

Shifting the log on the right side, it will become exponential

x = [tex]e^{-2}[/tex]

x = 0.135

x = 0.14 (two decimal places)

Answer:

Step-by-step explanation:

190 is half of 380

190 x 2 = 380

First get the average passing yards:

(3,832 + 3,779 + 3,655 + 3,642 + 3,579) / 5 = 3,697.4

Now get the squared residuals for each quarterback's passing yards. That is, compute the difference between each data and the average, then square the result. For example,

(3,832 - 3,697.4)^2 = 134.6^2 = 18,117.2

For the others, you should get squared residuals of

6,658.56

1,797.76

3,069.16

14,018.6

Take the sum of the squared residuals, then - since this is a sample, and not a population of all quarterbacks - divide the sum by 5 - 1 = 4 to get the variance:

(18,117.2 + 6,658.56 + 1,797.76 + 3,069.16 + 14,018.6)/4 = 10,915.3

The standard deviation is just the square root of the variance:

√(10,915.3) ≈ 104.48

Answer:

-525 feet

Step-by-step explanation:

If a submarine was below sea level, that would mean that it would be at an elevation of negative feet down, so if it's 800 feet below sea level, it's elevation would be -800.

to ascend means to rise, so the submarine would be moving +275 feet (going higher, closer to sea level)

so you can make out this equation: -800 + 275

this would equal: -525
