Answer: 416, 622

Step-by-step explanation:

First, let's look at the hundred thousands place.

We have 4 hundred thousand, which can be rewritten as 400,000.

Then, we have our ten thousand place in which we have sixteen thousand, which can be rewritten as 16,000.

Next, we have our hundreds place. Here, we have four-hundred, or 400.

After that, we have 21 tens, which can be rewritten as 210.

Lastly, we have 12 ones.

Now, if we add all of these together, we get:

400,000 + 16,000 + 400 + 210 + 12 = <em>416,622</em>

(Hope this helps!)

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard d
MatroZZZ [7]

The correct option is ''The value of 135 because it is not greater than 136.5 values is outside the 99% confidence interval for the population mean''

<h2>Given that,</h2>

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard deviation of 34.

<h3>We have to find,</h3>

Which of the following values is outside the 99% confidence interval for the population mean?

<h3>According to the question,</h3>

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard deviation of 34.

Sample space n = 85,

Mean = 146

And standard deviation = 34

Then, The standard error of the sample is,

= \dfrac{\sigma}{n}\\\\= \dfrac{34}{\sqrt{85}}\\\\= \dfrac{34}{9.21}\\\\= 3.6

Then, z-critical value for 99% is 2.58,

Margin of error = ±9.515

Confidence interval for lower bound is,

= 146 - 9.515 = 136.485

And confidence interval upper bound is,

= 146 + 9.515 = 155.515

Here, 135 is less than the lower bound,

Therefore, 135 does not lie within a 99% confidence interval.

For more details about Lower bound refer to the link given below.

Find the perimeter of a circle whose radius is 3.5cm. (Take pi = 22/7)
mrs_skeptik [129]

Answer:

P = 44

Step-by-step explanation:

The formula for the perimeter (circumference) of a circle is;

C = πd

C = 2πr

C = 2π (3.5)2

C = 2π7

C = 2 * 22/7 * 7

C = 2 * 22

C = 44

Question 1<br> Find the area of the shaded region.<br> 18 ft<br> 15 ft<br> 8 ft<br> A = ft?
qwelly [4]

Answer:

<h2>135 ft²</h2><h2 />

Step-by-step explanation:

see attached image

<u>shaded area = total area (1)  - unshaded triangular area (2)</u>

1.  area of a trapezoid = (a + b) * h/2

   where a = 8,  b = 18,  h = 15

   Area of trapezoid = (8 + 18) * 15/2 = 195 ft²

2.  Area of unshaded triangle = 1/2 (8) 15 = 60 ft²

shaded area =  195 - 60 = 135 ft²
