Answer:

4.5 > 4.420

0.67 < 0.8

0.82 = 0.820

62.4 > 6.24

0.13, 0.3, 0.303, 0.32

0.08, 0.8, 0.82, 8.2

24.54, 24.4, 24.304, 24.24

6.5, 6.25, 6.05, 6.007

Step-by-step explanation:

The most useful way to compare fractions is to add extra zeros at the end.

For example, 0.67 ___ 0.80.

0.80 is obviously bigger than 0.67.

In 24.4, 24.54, 24.304, 24.24, you can add extra zeros as well.

24.400, 24.540, 24.304, 24.240 (This makes it much easier to group the numbers, whether from largest to smallest or smallest to larger).

**REMEMBER TO REMOVE THOSE ZEROS AFTER FINDING YOUR FINAL ANSWER**

One number exceeds another by 26. the sum of the numbers is 58. what are the numbers

Gnom [1K]

First number = X

second number = x +26 ( exceeds means higher so add 26)

x + x+26 = 58

combine like terms:

2x + 26 = 58
subtract 26 from each side:

2x = 58-26

2x = 32

divide both sides by 2:
x = 32/2
x = 16

first number is 16
second number = 16+26 = 42

Find the measure of each interior angle of a regular octagon. (A regular polygon is one that has all the same sides and angles).

NemiM [27]

The interior angle of a regular octagon is 135 degrees.

<h3>What is an octagon?</h3>

An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.

Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.

Therefore,

n = number of sides = 8

Hence,

interior angle = (n - 2)180 / n

interior angle = (8 - 2)180 / 8

interior angle = 6 × 180 / 8

interior angle = 1080 / 8 = 135°

Use the standard norml distribution or the t-distribution to construct a 99% confidence interval for the population mean. Justif

dalvyx [7]

Answer:

E) we will use t- distribution because is un-known,n<30

the confidence interval is (0.0338,0.0392)

Step-by-step explanation:

Given sample size is n = 23<30 mortgage institutions

The mean interest rate 'x' = 0.0365

The standard deviation 'S' = 0.0046

the degree of freedom = n-1 = 23-1=22

99% of confidence intervals $t_{0.01} =2.82$ (from tabulated value).

$The mean value = 0.0365$

$x±t_{0.01} \frac{S}{\sqrt{n-1} }$

$0.0365±2.82 \frac{0.0046}{\sqrt{23-1} }$

$0.0365±2.82 \frac{0.0046}{\sqrt{22} }$

$0.0365±2.82 \frac{0.0046}{4.690 }$

using calculator

$0.0365±0.00276$

Confidence interval is

$(0.0365-0.00276,0.0365+0.00276)$

$(0.0338,0.0392)$

the mean value is lies between in this confidence interval

(0.0338,0.0392).

<u>Answer:-</u>

<u>using t- distribution because is unknown,n<30,and the interest rates are not normally distributed.</u>

The change of rate is

irakobra [83]

ROC is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another; graphically, the rate of change is represented by the slope of a line. The ROC is often illustrated by the Greek letter delta.

Find the volume r:7 h:7

sweet-ann [11.9K]

Answer:

V = 1077.566 units²

Step-by-step explanation:

Assuming this is a cylinder, the formula is (area of base) × (height)

or (πr²)(h), simply plug-in the given values:

= (π(7)²)(7)

= (153.938)(7)

V = 1077.566 units²
