Answer 1
Answer: first one

20cm=diameter
perimiter of this one is (pi times radius^2)divided by 2+ 20

diameter=2radius
radius=diameter times 1/2
diameter=20
20/10=radius=10

3.14 times 10^2=314
314 times 1/2=157
157+20=177 cm
perimiter=177 cm

james buys a video game for his xbox for 49.99 a controller for 34.95 and a walk through manual for 19.99 the sales tax in his area is 8.25% what will be the total cost of his purchase

Answers

Cost of the video game bought by James = 49.99
Cost of the controller bought by James = 34.95
Cost of the walk through manual bought by James = 19.99
Percentage of sales tax in the area of James = 8.25%
Total amount spent by James for buying the goods = 49.99 + 34.95 + 19.99
                                                                                  = 104.93
Amount of sales tax = (8.25/100) * 104.93
                                 = 865.67/100
                                 = 8.66
So the total amount paid by James including tax = 104.93 + 8.66
                                                                              = 113.59
So the total cost of the purchase made by James is 113.59. I hope the procedure is clear enough for you to understand.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the value of A = 2,983,785

Let the tens place be represented as a

Let the ten thousands place be represented as b

Now , the first number 8 is in the tens place , so a = 8 x 10 = 80

The second number 8 is in the ten thousands place , so b = 8 x 10000 = 80,000

Hence , the value of number 8 is in tens and ten thousands place

PLEASE HELPResults of a blood test are normally distributed with a mean of 6.2 and a standard deviation of 1.5. What is the probability that a patient has a blood test result less than or equal to 8.3?

Answers

Answer:

91.92%

Step-by-step explanation:

Given that:

Mean (μ) = 6.2, standard deviation (σ) = 1.5

Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:

z=(x-\mu)/(\sigma)

To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3

For x = 8.3, the z score is:

z=(x-\mu)/(\sigma)=(8.3-6.2)/(1.5) =1.4

From the probability distribution table:

P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%
