2/3b+5=20-b can someone help me out plz because i keep getting this wrong

1) Find the circumference and area of each circle:

MA_775_DIABLO [31]

Answer:

a] Radius of circle = 10 feet

Circumference of circle = 94.2 feet (Approx.)

Area of circle = 314 feet² (Approx.)

b] Radius of circle = 6 cm

Circumference of circle = 37.68 cm (Approx.)

Area of circle = 113.04 cm² (Approx.)

Step-by-step explanation:

Given:

a] Radius of circle = 10 feet

b] Radius of circle = 6 cm

Find:

Circumference an area for both circle

Computation:

Circumference of circle = 2πr

Area of circle = πr²

a] Radius of circle = 10 feet

Circumference of circle = 2(3.14)(10)

Circumference of circle = 94.2 feet (Approx.)

Area of circle = (3.14)(10)²

Area of circle = 314 feet² (Approx.)

b] Radius of circle = 6 cm

Circumference of circle = 2(3.14)(6)

Circumference of circle = 37.68 cm (Approx.)

Area of circle = (3.14)(6)²

Area of circle = 113.04 cm² (Approx.)

Find the mean, median, and mode of the data set. Round to the hundredths, if necessary. 29,300 24,350 32,400 15,100 14,200 21,95

Sav [38]

The mean of the data is 20038.24, the median is 16050 while the number with the highest frequency is 11500

<h3>Mean, median, and mode of a dataset</h3>

Mean are known as averages, median is the middle value after rearrangement while the mode is the value with the highest frequency

Calculate the mean

Mean = sum of data/sample size

Given the data

29300, 24350, 32400, 15100, 14200, 21950, 27450, 29400, 15200, 35050, 16050, 11500, 13050, 11500, 11600, 11100, 21450

The mean of the data is 20038.24

For the median being the value at the middle, the median is 16050 while the number with the highest frequency is 11500

Write or draw to explain two ways you can find the sum of 3+4+5

Hitman42 [59]

3+4+5=7+5=12
4+5+3=9+3=12
In addition the order of the numbers don't matter.

It is known that only 1% of U.S citizens living on East Coast will be exposed to Lyme disease. There is a blood test they can de

aniked [119]

We need to find the probability that a randomly selected US citizen living on the East Cost will be exposed to Lyme disease and test positive.

We know that 1% of U.S citizens living on the East Coast will be exposed to Lyme disease. And only 95% of them will test positive.

Thus, the probability that this person will be exposed to Lyme disease and test positive is given by:

$95\%\cdot1\%=\frac{95}{100}\cdot\frac{1}{100}=\frac{95}{10000}=0.0095$

Answer: 0.0095
