9514 1404 393

Answer:

  316 lumens/m²

Step-by-step explanation:

We assume your intensity function is ...

  f(x) = 50,000(0.975^x) . . . . x meters below the surface

__

Use 200 for x and do the arithmetic.

  f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²

Luke’s dad need 165 for a new suitcase. If he saves an equal amount for 3 weeks, how much does save each week?
goldenfox [79]
This is easy the answers 55 you just need to divide

165 ÷ 3 = ?

Step 1: Look at the multiplications of three can you make a group with an answer close to one? if not look at 16 and the multiplications of three is there a number close to 16 or exact?

Step 2: In this case 5 × 3 = 15, so 15 is close to 16.


Step 3: Now you need to subtract 16 and 15, 16 - 15 = 1.


Step 4: Like there's no number that has 1 as a answer, you need to lower the 5.


Step 5: Once you lower the five it makes 15 in the in the multiplications of three is there something close to 15 or exact? Yes there is a number that can make 15, it's 5 × 3 so 15 take away 15 makes zero so your answer will be simple, 55.

So Luke's dad needs to save $55 each week.

(sorry if their is spelling errors)

You could work backwards. -9+5 = -4. Then, -4-2 = -6.
It was -6°C at 3 p.m.
Hope that helped you.

On the basis of data provided by a salary survey, the variance in annual salaries for seniors in public accounting firms is appr
iogann1982 [59]

Answer:

We conclude that there is a significant difference between the variances of salaries for seniors and managers.

Step-by-step explanation:

We are given the following in the question:

s_1^2 = 2.3, n_1 = 25\\s_2^2 = 12.3, n_2 = 26

Alpha, α = 0.05

First, we design the null and the alternate hypothesis

H_{0}: \sigma_1^2 = \sigma_2^2\\H_A: \sigma_1^2 \neq \sigma_2^2  

We use F-test to determine the difference in variation between the two samples.

Formula:

F_{stat} = \displaystyle\frac{s_2^2}{s_1^2}\\\\(As ~s_2 > s_1)

Putting all the values, we have

F_{stat} = \displaystyle\frac{12.3}{2.3} = 5.3478  

Now we calculate the p-value at degree of freedom(26-1 = 25, 25-1 = 24)

P-value = 0.000053

Since the p value is less than the significance level, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.

Thus, we conclude that there is a significant difference between the variances of salaries for seniors and managers.
